The electrolytic cleaning apparatus 1 performs electrolytic cleaning of the mold W by energizing the cathode 3 and the anode 4 while the cathode 3 and the anode 4 are immersed in the electrolytic solution L. Thus, the electrolytic cleaning is performed in a state where the anode 4 is located at the facing position X facing the cathode 3 in the depth direction.

  As shown by a two-dot chain line in FIGS. 3 and 4, at the facing position X, when the electrolytic cleaning apparatus 1 is viewed in plan, the anode 4 and the cathode 3 overlap each other in the depth direction. Specifically, at the facing position X, the anode body 41 of the anode 4 and the mounting body 21 of the cathode 3 overlap in the depth direction. In addition, the anode 4 is arranged so that the support rod 421 is in an upright posture at the facing position X. Specifically, the anode 4 is disposed at the facing position X so that the axial direction of the support bar 421 is along the depth direction.

  Next, a procedure for moving the anode 4 will be described.

  After the completion of the electrolytic cleaning, the operator holds both ends of the mounting bar 43 of the anode 4 and lifts the anode 4 to such an extent that the anode 4 floats lightly from the hook portion 22b. Subsequently, as shown in FIG. 3, the operator moves the anode 4 in the lateral direction so that the anode 4 is positioned above the anode retracting region P (in the direction of the arrow in FIG. 3). The operator moves the anode 4 so that the anode body 41 is immersed in the electrolyte L. At that time, since the anode 4 passes through the opening R formed in the side surface portion 20 of the cathode 3, the operator can easily move the anode 4 by slightly lifting the anode 4. There is no risk of contact with the cathode 3. The operator locks both ends of the mounting bar 43 of the anode 4 to the edge 51 of the cleaning tank 5, and positions the anode 4 in the anode retracting area P. Specifically, the operator locks both ends of the mounting bar 43 of the anode 4 to the mounting table 8 and positions the anode 4 in the anode retracting area P. The operation of moving the anode 4 may be performed in either a state where power is supplied to the anode 4 or a state where power supply to the anode 4 is stopped. In addition, when the lead wire is connected to the anode 4, the operation of moving the anode 4 is performed in a state where the lead wire is connected. For the cordless type anode 4, the anode 4 and the anode power feeding portion are connected. After releasing the lock.

  In order to prevent the anode 4 from coming into contact with the cathode 3 during the movement of the anode 4, for example, a portion other than a contact portion with the cathode power feeding portion (a portion exposed to the anode 4) in the cathode 3 is covered. Alternatively, the operator moves the anode 4 on the locking edge 9 made of resin.

  Next, the positional relationship between the cathode 3 and the anode 4 when the cathode 3 is taken out from the cleaning tank 5 will be described.

  As shown by the solid lines in FIGS. 3 and 4, the anode 4 is located in the anode retracting region P and thus is located in the retracted position Y that is not opposed to the cathode 3 in the depth direction. At the retracted position Y, the anode 4 and the cathode 3 are separated in the lateral direction when the electrolytic cleaning apparatus 1 is viewed in plan. Specifically, at the retracted position Y, the anode body 41 of the anode 4 faces the bottom of the cleaning tank 5 without the cathode 3 interposed therebetween. The anode 4 is disposed in the retracted position Y so that the support bar 421 is in an upright posture. Specifically, the anode 4 is disposed at the retracted position Y so that the axial direction of the support bar 421 is along the depth direction.

  The explanation of the electrolytic cleaning apparatus 1 according to the first embodiment is as described above. Next, the electrolytic cleaning apparatus 1 according to the second embodiment will be described with reference to the drawings. Note that the description common to the first embodiment will not be repeated.

  As shown in FIGS. 5 to 7, in the second embodiment, two anodes 4 are provided. The two anodes 4 are installed in the cleaning tank 5 so as to be adjacent in the horizontal direction. The anode retreat area P has a space for positioning the two anodes 4. In the present embodiment, the anode retracting area P is formed on both sides of the cathode 3 in the lateral direction. That is, the anode retreat area P includes a first anode retreat area P1 formed on one side face 20 side of the side faces 20 of the cathode 3 in the horizontal direction and a second anode retreat area P1 formed on the other side face 20 side. And an anode retracting region P2. The electrolytic cleaning apparatus 1 of the present embodiment is configured such that one of the two anodes 4 is positioned in the first anode retracting region P1 close to the one anode 4 and the other anode 4 is the other anode. 4 is configured to be positioned in the second anode retreat area P2 close to 4. That is, in this embodiment, as shown in FIG. 6, the two anodes 4 are moved in the opposite direction in the lateral direction (the direction of the arrow in FIG. 6).

  Next, the electrolytic cleaning apparatus 1 according to the third embodiment will be described with reference to the drawings. In addition, description is not repeated about the part which is common in 1st Embodiment and 2nd Embodiment.

Further, the driving unit 100 moves the anode 4 from the facing position X to the retracted position Y, and then positions the mounting unit 2 at the non-cleaning position F. The drive unit 100 of the present embodiment moves the anode 4 and the placement unit 2 with separate drive units 100. Therefore, the drive unit 100 includes a first drive unit (not shown) that moves the anode 4 and a second drive unit 300 that moves the placement unit 2. However, the anode 4 and the mounting unit 2 can be moved by one driving unit 100 by a control device such as shifting the timing of movement of the anode 4 and the mounting unit 2. In this case, the number of driving units 100 can be reduced, which is advantageous in terms of cost.

  At the cleaning position C, the mold W is immersed in the electrolytic solution L. At the cleaning position C, the mounting body 21 is immersed in the electrolyte L, and the anode 4 is positioned at the facing position X without interfering with (without contacting with) the mounting portion 2. In the non-cleaning position F, the mold W is located above the liquid surface of the electrolytic solution L (not immersed in the electrolytic solution L). In the non-cleaning position F, the mounting body 21 is in a state of protruding from the liquid surface of the electrolytic solution L, and is positioned at substantially the same height as the locking edge 9.

Specifically, the anode 4 is configured such that both ends of the mounting bar 43 are placed on each of the pair of vertical locking edges 91 of the locking edges 9 and slide on the upper surface of the locking edges 9. It has become. Therefore, the vertical locking edge 91 is a rail for sliding the end of the mounting bar 43. The locking edge 9 of this embodiment is formed of Duracon (registered trademark).

  The second driving unit 300 is connected to the mounting unit 2, and the mounting unit 2 moves between the cleaning position C and the non-cleaning position F as the second driving unit 300 moves up and down in the depth direction. The second driving unit 300 includes a second connecting unit 310 connected to the placement unit 2 and a motor 320 for moving the second connecting unit 310 up and down. A pair of second driving units 300 are provided in the vertical direction via the cleaning tank 5, and each second driving unit 300 is connected to the extending portion 22 of the mounting unit 2. The pair of second drive units 300 moves up and down at the same timing and the same speed while being positioned at the same height in the depth direction, so that the horizontal posture of the mounting unit 2 is maintained (the mounting main body 21 is The mounting part 2 is moved up and down (while being kept horizontal). The second drive unit 300 is installed outside the cleaning tank 5. Specifically, the second connecting portion 310 is installed between the outer side surface of the cleaning tank 5 and the inner side surface of the apparatus main body 10. Further, the motor 320 is installed below the bottom surface of the cleaning tank 5.

  The second connecting portion 310 is connected to the placement portion 2 by the placement portion 2 being hooked. The second connecting portion 310 includes a hooking portion 311 on which the hooking portion 22b of the mounting portion 2 is hooked, and a motor 320 converted into a linear moving force so as to move the hooking portion 311 up and down in the depth direction. A moving portion 312 that moves up and down by the rotational force of the first portion, and an intermediate portion 313 that connects the latching portion 311 and the moving portion 312.

  The latching portion 311 is a rod-like member that extends in the lateral direction. The moving part 312 is a rod-like member extending in the depth direction. In the moving unit 312, the rotational force of the motor 320 is converted into a vertical moving force by a power transmission means using a gear such as a rack and pinion, and moves in the depth direction in response to the moving force. . The intermediate portion 313 includes a first portion 313 a that extends in the depth direction and is connected to the latch portion 311, and a second portion 313 b that extends in the lateral direction and is connected to the moving portion 312.

Further, the first portion 313a penetrates the second portion 313b in the depth direction, and extends downward from the second portion 313b.

  The anode power feeding unit 110 feeds power to the mounting bar 43 of the anode 4. The anode power supply unit 110 is connected to the connection means 120. The anode power feeding unit 110 feeds power to the mounting bar 43 connected to the connecting means 120. The anode power feeding part 110 is connected to the lower surface of a contact part 121 described later.

  The connection means 120 connects the contact portion 121 that is an electrical contact with the anode 4, a detection portion (not shown) that detects that the anode 4 is located at the facing position X, and the anode 4 and the contact portion 121. Connecting portion 122 for the purpose. The connection means 120 of this embodiment is formed of a U-shaped metal member, and has a pair of pieces separated in the depth direction. A lower piece on the lower side in the depth direction functions as a contact portion 121, and a connecting portion 122 is provided on the upper surface of the upper piece on the upper side. The pair of pieces opens toward the retracted position Y, and the end of the attachment bar 43 of the anode 4 that moves from the retracted position Y to the facing position X is received between the pair of pieces.

  The detection unit is a sensor that can detect that the anode 4 is located at the facing position X, such as a limit switch or a line sensor that can detect the position of the anode 4. The connection part 122 connects the anode 4 and the contact part 121 by pressing the anode 4 located at the facing position X against the contact part 121. The connection part 122 is an air cylinder, for example.

  Hereinafter, the operation of the electrolytic cleaning apparatus 1 of the present embodiment will be described.

  Before the electrolytic cleaning apparatus 1 is activated, the mounting portion 2 is positioned at the cleaning position C, and the anode 4 is positioned at the facing position X. An operator starts the electrolytic cleaning apparatus 1 through input means such as a switch provided on the control panel after predetermined preparation such as pouring the electrolytic solution L into the cleaning tank 5. The operator raises the placement unit 2 to the non-cleaning position F. FIG. 9 shows an external view of the cleaning target W after cleaning, but is also an external view of the state before cleaning. As shown in FIG. 9, the mold W is placed on the placing body 21 in a state where the placing portion 2 is located at the non-cleaning position F and the anode 4 is located at the retracted position Y.

  When the operator performs an operation for starting cleaning (for example, pressing a start button), the placement unit 2 starts to descend. When the mounting portion 2 is lowered to the cleaning position C (see FIG. 8), the anode 4 starts to move from the retracted position Y to the facing position X and stops at the facing position X. In the present embodiment, the movement of the anode 4 starts after the placement unit 2 is completely located at the cleaning position C. However, if the placement unit 2 and the anode 4 do not interfere with each other (if they do not contact), the placement is performed. It is also possible to start the movement of the anode 4 while the part 2 is descending, and to shorten the time until the start of cleaning.

  When the detection unit detects that the anode 4 is located at the facing position X, the control unit supplies air to the connection unit 122 and causes the anode 4 to contact the contact unit 121. When the anode 4 comes into contact with the contact part 121, power supply from the anode power supply unit 110 to the anode 4 is started. If it does so, it will be in the state which can be washed and washing will be started automatically.

  When the predetermined time has elapsed and cleaning is completed, the control unit stops power supply from the anode power supply unit 110 to the anode 4. The control unit stops supplying air to the connection unit 122 and releases the connection between the anode 4 and the contact unit 121. When the anode 4 becomes free with respect to the contact portion 121, the control unit moves the anode 4 from the facing position X to the retracted position Y. When the anode 4 moves to the retreat position Y, the placement unit 2 starts to rise from the cleaning position C. In the present embodiment, the placement unit 2 starts to rise after the anode 4 is completely located at the retracted position Y. However, if the placement unit 2 and the anode 4 do not interfere (if they do not contact), the anode 4 It is also possible to start the ascent of the mounting portion 2 during the movement of the movement and to shorten the time after cleaning.

  Hereinafter, the operation of the present embodiment will be summarized. According to the electrolytic cleaning apparatus 1 of the present embodiment, the cleaning tank 5 is formed with the anode retracting region P for retracting the anode 4 around the cathode 3 as the mounting portion 2. The position can be changed between a facing position X facing the cleaning tank 5 in the depth direction of the cleaning tank 5 and a retracting position Y not facing the cathode 3 in the depth direction by being positioned in the anode retracting area P. It is configured. Therefore, the position of the anode 4 is changed inside the cleaning tank 5 from the state facing the cathode 3 in the depth direction of the cleaning tank 5 to the state not facing the cathode 3 in the depth direction. Can do. Therefore, according to such a configuration, the cathode 3 can be easily taken out without taking the electrolyte L in the cleaning tank 5 out of the cleaning tank 5 by changing the position of the anode 4 from the facing position X to the retracted position Y. be able to.

  Further, in the above embodiment, the anode 4 is arranged so that the support bar 421 is in an upright position at the retracted position Y. Therefore, the support bar 421 is inclined at the retracted position Y or is in a sleeping position. Compared with the case where it has become, the electrolyte solution L adhering to the anode 4 can be dropped to the narrow range in the washing tank 5. In addition, since the support rod 421 is arranged so as to stand upright at the retracted position Y, the electrolyte L can easily travel along the support rod 421, so that the electrolyte L can be dropped in a narrow range. . Furthermore, since the support bar 421 is arranged in an upright position at the retreat position Y, the support bar 421 hardly protrudes from the cleaning tank 5, and liquid dripping hardly occurs outside the cleaning tank 5.

  Further, in the above embodiment, the cathode 3 is the mounting main body 21 for mounting the cleaning object W and the extending portion 22 extending from the mounting main body 21, and the edge 51 of the cleaning tank 5. And the extending portion 22 having the hooking portion 22b for hooking to the cleaning tank 5, the mounting body 21 can be moved to the cleaning tank 5 via the extending portion 22 simply by hooking the hooking portion 22b to the edge 51 of the cleaning tank 5. Installed inside. Further, both ends of the mounting bar 43 are configured to be able to be engaged with the hook portion 22b of the cathode 3 at the facing position X, and are configured to be able to be engaged with the edge 51 of the cleaning tank 5 at the retracted position Y. ing. Therefore, the operator can install the anode 4 in the cleaning tank 5 simply by locking the anode 4 to the hook portion 22 b of the cathode 3 or the edge 51 of the cleaning tank 5. As described above, according to such a configuration, the cathode 3 can be easily installed in the cleaning tank 5, and the anode 4 can be easily moved between the facing position X and the retracted position Y.

  Further, in the above embodiment, when the anode 4 is changed between the facing position X and the retracted position Y, the anode 4 can pass through the opening R formed in the side surface portion 20 of the cathode 3. The position of the anode 4 can be easily changed without interference between the anode 3 and the anode 4.

  Further, in the above embodiment, the anode retracting area P is formed on the outer side in the lateral direction perpendicular to the depth direction of the cleaning tank 5 with respect to the cathode 3 installed in the cleaning tank 5. Is moved to the opposite position X and the retracted position Y, the anode 4 is moved in the lateral direction of the cleaning tank 5. Here, the cathode 3 is hooked by the pair of vertically opposed edges 511 facing each other in the vertical direction perpendicular to the depth direction and the horizontal direction of the edge 51 of the cleaning tank 5 in the cleaning tank 5. Is installed. Therefore, according to the above configuration, since the hook portion 22b is not positioned in the moving direction of the anode 4, the hook portion 22b is not easily obstructed when the anode 4 is moved, and the anode 4 is easily moved. Moreover, since the hook part 22b is hooked by a pair of opposing vertical opposing edges 511, the cathode 3 can be stably installed with respect to the washing tank 5. Furthermore, since the handle portion 22b is provided with the handle portion 22c, the operator can easily take out the cathode 3 by holding the handle portion 22c.

  For example, with respect to the large cathode 3 used when cleaning the large mold W, the cathode 3 is taken out from the cleaning tank 5 while being suspended by a lifting means such as a hoist. An electrolytic cleaning apparatus 1 in which an anode 4 is fixed to a lid for closing the cleaning tank 5, and a large amount of gold is used by using the type of electrolytic cleaning apparatus 1 in which the anode 4 is removed from the cleaning tank 5 when the cover is opened. When cleaning the mold W, since the anode 4 is exposed on the cleaning tank 5, there is a problem that when the cathode 3 is lifted, the cathode 3 is shaken and hits the anode 4. In the above embodiment, since the anode main body 41 and the support bar 421 are located in the cleaning tank 5 at the retracted position Y, when the cathode 3 is taken out, it is difficult to collide with the anode 4 even if the cathode 3 is shaken. 3 can be taken out safely. Similarly, when the large mold W is directly removed, the mold W can be safely removed.

  In the above-described embodiment, since the through hole H is formed in the base portion 211, the electrolytic solution L can freely come out from the lower side of the mounting body 21 or from the upper side to the lower side. The electrolytic solution L is prevented from staying between the mounting main body 21 and the mold W, the lower surface side of the mounting main body 21 or the like. In addition, since the through hole H is formed in the base portion 211, the liquid can be drained when the cathode 3 is lifted, so that the cathode cleaning can be performed without taking the electrolyte L out of the cleaning tank 5. The cathode 3 can be moved to a washing tank or the like. Moreover, since the electrolytic solution L can be returned into the cleaning tank 5 by being able to drain the liquid, it is possible to prevent the electrolytic solution L in the cleaning tank 5 from being reduced.

  In the said embodiment, the connection part 222 is connected to this 1st elongate part 221a so that it may protrude upwards with respect to the 1st elongate part 221a. Therefore, even if the cathode 3 is placed on the edge 51 of the cleaning tank 5, an opening is formed between the edge 51 of the cleaning tank 5 and the connecting portion 222, so that an operator can easily hold the connecting portion 222. ing.

  In the mounting table 8 of the above-described embodiment, the height of the body portion 82 is adjusted so that the bottom of the recess 81 is substantially the same height as the upper surface of the connecting portion 222. By adjusting the height of the body 82 in this way, the height of the anode 4 is made substantially equal at the facing position X and the retracted position Y, and the anode 4 is immersed in the electrolyte L at the retracted position Y. At the same time, the anode main body 41 is prevented from hitting the bottom of the cleaning tank 5.

  In the above embodiment, since the anode retracting area P is formed on the work table 7 side, the anode 4 does not get in the way when the cathode washing water tank is installed on the opposite side of the work table 7. It is easy to move 3 to the washing tank.

  In the above embodiment, the electrolytic cleaning apparatus 1 includes the drive unit 100 that moves at least one of the anode 4 and the mounting unit 2, and thus at least one of the anode 4 and the mounting unit 2 is automatically operated. Can be moved. This eliminates the need for the operator to manually move at least one of the anode 4 and the placement unit 2, thereby reducing the operator's workload.

  In the above-described embodiment, the driving unit 100 is configured to move the anode 4 and the mounting unit 2. After the mounting unit 2 is lowered from the non-cleaning position F to the cleaning position C, the anode 4 is opposed to the driving unit 100. Position at position X. According to such a configuration, after the placement unit 2 is lowered from the non-cleaning position F to the cleaning position C, the operation of positioning the anode 4 at the facing position X can be automatically performed.

  Further, in the above embodiment, after the anode 4 is moved from the facing position X to the retracted position Y, the placement unit 2 is positioned at the non-cleaning position F. According to such a configuration, after the anode 4 is moved from the facing position X to the retracted position Y, the operation of positioning the mounting portion 2 at the non-cleaning position F can be automatically performed.

  In the above embodiment, the electrolytic cleaning apparatus 1 includes the anode power feeding unit 110 that feeds power to the anode 4 and the connection means 120 that electrically connects the anode 4 located at the facing position X and the anode power feeding unit 110. Yes. According to such a configuration, the anode 4 positioned at the facing position X and the anode power feeding unit 110 can be reliably electrically connected by the connecting means 120.

  In addition, the electrolytic cleaning apparatus 1 of the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

  In the above embodiment, the case where the anode 4 is moved to the retracted position Y by the movement of the anode 4 has been described. However, the present invention is not limited to this. That is, the placement unit 2 may be positioned at the retracted position Y by moving the placement unit 2.

  Specifically, the electrolytic cleaning apparatus 1 includes a mounting unit 2 for mounting the cleaning object W, a cathode 3 electrically connected to the mounting unit 2, an anode 4, and an electrolytic solution L. In the state where the anode 4 is installed on the mounting portion 2 so as to face the mounting portion 2 in the depth direction of the cleaning tank 5. In the electrolytic cleaning apparatus 1 for electrolytically cleaning the object to be cleaned W by energizing between the cathode 3 and the anode 4, the mounting portion 2 is retracted around the anode 4 in the cleaning tank 5. A placement portion retreat area is formed, and the placement portion 2 is positioned in the placement portion retraction region, the facing position facing the anode 4 in the depth direction, and the anode 4. However, the position may be changed to a retreat position that is not opposed to the depth direction.

  According to such a configuration, in the cleaning tank 5, a placement portion retreat area for retracting the placement portion 2 is formed around the anode 4, and the placement portion 2 has a cleaning tank 5 with respect to the anode 4. It is possible to change the position between an opposing position facing in the depth direction and a retracting position that is located in the placement portion retracting area and is not facing the anode 4 in the depth direction. Therefore, the position of the mounting portion 2 is changed inside the cleaning tank 5 from the state facing the anode 4 in the depth direction of the cleaning tank 5 to the state not facing the anode 4 in the depth direction. can do. Therefore, according to such a configuration, the placement unit 2 can be easily moved without taking the electrolyte L in the cleaning tank 5 out of the cleaning tank 5 by changing the position of the mounting part 2 from the facing position to the retracted position. Can be taken out.

  Moreover, you may make the mounting part 2 and the anode 4 a non-opposing state by moving both the anode 4 and the mounting part 2. FIG.

  Specifically, the electrolytic cleaning apparatus 1 includes a mounting unit 2 for mounting the cleaning object W, a cathode 3 electrically connected to the mounting unit 2, an anode 4, and an electrolytic solution L. In the state where the anode 4 is installed on the mounting portion 2 so as to face the mounting portion 2 in the depth direction of the cleaning tank 5. In the electrolytic cleaning apparatus 1 for electrically cleaning the object to be cleaned W by energizing between the cathode 3 and the anode 4, the anode 4 and the mounting portion 2 face each other in the depth direction. And the position of the anode 4 and the mounting part 2 is the position of the cleaning tank 5 so that the anode 4 and the mounting part 2 are switched to a non-opposing state where they are not facing each other in the depth direction. It may be configured to be changeable inward.

  According to such a configuration, the electrolytic cleaning apparatus 1 includes the facing state in which the anode 4 and the mounting portion 2 face each other in the depth direction of the cleaning tank 5, and the anode 4 and the mounting portion 2 in the depth direction. The positions of the anode 4 and the mounting portion 2 are configured to be changeable inside the cleaning tank 5 so as to switch to a non-opposing state where they are not facing each other. Therefore, the position of the anode 4 and the mounting portion 2 can be changed inside the cleaning tank 5 from a state where they face each other in the depth direction of the cleaning tank 5 to a state where they do not face each other in the depth direction. Therefore, according to such a configuration, the mounting portion 2 can be easily taken out without taking the electrolytic solution L in the cleaning tank 5 out of the cleaning tank 5.

  As described above, when the mounting unit 2 is moved and when the anode 4 and the mounting unit 2 are moved, the mounting unit 2 itself may be the cathode 3.

  Although not particularly mentioned in the above embodiment, as shown in FIG. 10, a partition V for partitioning the cleaning tank 5 may be provided in the cleaning tank 5. FIG. 10 shows a state in which the partition V is provided in the cleaning tank 5 of the first embodiment. FIG. 11 shows a state in which the partition V is provided in the cleaning tank 5 of the second embodiment.

  The partition V partitions the cleaning tank 5 into a cathode installation area Q in which the cathode 3 is installed and an anode withdrawal area P. The partition V of this embodiment is provided along the vertical direction. The partition V may be a partition that completely partitions the cleaning tank 5 into the cathode installation region Q and the anode retracting region P, or the anode retracting region P is clarified so as to be a guide for the position where the anode 4 is retracted. For the purpose, the cleaning tank 5 may be partially partitioned. The partition V may be, for example, a metal material or a resin material.

  Moreover, although the said embodiment demonstrated the case where the height of the trunk | drum 82 was adjusted so that the bottom part of the recessed part 81 might become substantially the same height as the upper surface of the connection part 222, it is not limited to this. Absent. As shown in FIG. 12, the height of the body portion 82 may be adjusted so that the bottom of the recess 81 is positioned higher than the upper surface of the connecting portion 222. In this case, as shown in FIG. 13, the anode body 41 comes out of the electrolyte L by moving the anode 4 to the retracted position Y. In this case, since the current can be stopped simultaneously with the movement of the anode 4 to the retracted position Y, it is effective when it is desired to stop the electrolytic cleaning simultaneously with the movement of the anode 4. Alternatively, the anode main body 41 may be immersed in the electrolytic solution L at the retracted position Y. In this case, the height of the body portion 82 may be adjusted so that the anode body 41 is immersed in the electrolytic solution L in a state where the anode 4 is mounted on the mounting table 8.

  Although not particularly mentioned in the above embodiment, as shown in FIG. 14, when a plurality of anodes 4 are provided, the anode 4 is provided with a gripping portion 40 that connects the adjacent anodes 4 to each other. Also good. By providing the grip portion 40 on the anode 4, the plurality of anodes 4 can be moved at a time, and the work burden on the operator can be reduced. In this case, the anode retracting region P is formed on one side surface portion 20 of the side surface portions 20 in the lateral direction of the cathode 3 as in the first embodiment.

  Although the case where the metal mold | die W was wash | cleaned as the washing | cleaning target object W was demonstrated in the said embodiment, it is not limited to this. The object to be cleaned W may be formed of a metal that does not elute by electrolysis, and may be a metal plate, a metal pipe, or the like.

  In the above embodiment, the case where the placement unit 2 itself is the cathode 3 has been described. However, the present invention is not limited to this. The placement unit 2 and the cathode 3 may be configured separately. In this case, in order to perform electrolytic cleaning, a connecting unit that electrically connects the mounting portion 2 and the cathode 3 may be provided.

  In the above embodiment, the case where the operator lifts the anode 4 and moves the anode 4 has been described, but the present invention is not limited to this. The operator may slide the anode 4 while bringing the anode 4 into contact with the edge 51 of the cleaning tank 5.

  In the first embodiment, a case where one anode 4 is provided and a case where two anodes 4 are provided in the second embodiment has been described. However, three or more anodes 4 may be provided. . Moreover, although the case where the anode retreat area | region P was formed in the horizontal direction outward with respect to the cathode 3 was demonstrated, it is not limited to this. The anode retracting region P may be formed outside the cathode 3 in the vertical direction, or may be formed so as to surround the cathode 3.

  Although not particularly mentioned in the above embodiment, the anode 4 is preferably in a state in which the anode body 41 is immersed in the electrolytic solution L at the retracted position Y. Since the temperature of the anode body 41 rises from 50 ° C. to 60 ° C. along with the electrolytic cleaning, if the anode body 41 is left in a state where it is taken out from the electrolytic solution L, the surface of the anode body 41 is cooled. Along with this, crystals of the electrolytic solution L are deposited. In addition, if the anode body 41 contains an iron component, the anode body 41 is rusted. Therefore, for example, the body portion 82 of the mounting table 8 is configured to be adjustable in height according to the immersion depth of the anode body 41 so that the anode body 41 is immersed in the electrolyte L at the retracted position Y. Good. By doing in this way, even if the position of the support bar 421 is adjusted according to the size of the mold W, the height of the body portion 82 is adjusted to a height at which the anode body 41 is immersed in the electrolyte L. Since it is good, it is not necessary to adjust the position of all the support bars 421, and the work burden on the operator can be reduced.

  In the above embodiment, the case where the extending portion 22 is formed in a frame shape and the opening R is formed in the side surface portion 20 of the cathode 3 has been described. However, the shape of the cathode 3 is not limited to the above embodiment. Absent. The cathode 3 may be, for example, one in which the extending portion 22 is formed in a plate shape or one in which four sides are closed.

  In the above embodiment, the drive unit 100 has been described with respect to the case where the anode 4 and the placement unit 2 are moved, but the present invention is not limited to this. The drive unit 100 may move only one of the anode 4 and the placement unit 2.

  Although not particularly mentioned in the above embodiment, as shown in FIG. 9, the electrolytic cleaning apparatus 1 electrically connects the mounting unit 2 as the cathode 3 located at the cleaning position C and the cathode power feeding unit. The placement unit connection unit 140 may be further provided. The configuration of the mounting portion connecting means 140 is the same as the configuration of the connecting means 120. For example, a contact portion that is an electrical contact with the mounting portion 2 and that the mounting portion 2 is located at the cleaning position C. You may have the detection part (not shown) to detect, and the connection part for connecting the mounting part 2 and a contact part. The mounting portion connecting means 140 is formed of a U-shaped metal member and has a pair of pieces 141 that are spaced apart in the lateral direction. The piece 141a on one side in the lateral direction may function as a contact portion, and a connection portion may be provided on the side surface of the piece 141b on the other side. The pair of pieces 141 are open toward the upper side, and when the mounting portion 2 is lowered to the cleaning position C, for example, a part of the hook portion 22b may be received between the pair of pieces.

  Further, as shown in FIGS. 15A and 15B, the placement unit connecting means 140 is installed between a pair of pieces 141 facing each other with a space therebetween and the pair of pieces 141. 2, a plate-like contact piece 142 that contacts 2, an urging means 143 that urges the contact piece 142 inwardly between the pair of pieces 141, and the contact piece 142 in contact with the mounting portion 2. The fixing portion 144 may be provided. The pair of pieces 141 are each formed in a plate shape, and one end portions are connected to each other. The pair of pieces 141 has a substantially V shape in which the interval between the other end portions is wider than the interval between the one end portions. In a state where the mounting portion 2 is not inserted between the pair of pieces 141, the contact piece 142 is directed inwardly of the pair of pieces 141 (in the direction of the arrow in FIG. 15A) by the urging means 143. It is energized. As shown in FIG. 15A, when the mounting portion 2, for example, a part of the hook portion 22b is inserted between the pair of pieces 141 from the other end side, the corner portion S of the hook portion 22b comes into contact. One piece 141a of the piece 142 and the pair of pieces 141 comes into contact. In this state, since the contact piece 142 is urged toward the placement unit 2 by the urging means 143, the contact piece 142 is pressed against the placement unit 2. The urging means 143 is a spring.

  The contact piece 142 is urged toward the mounting portion 2 by the urging means 143, and the distance between the pair of pieces 141 is narrowed toward the one end portion due to the V shape. Therefore, when the mounting portion 2 is further pushed in with a part of the hook portion 22b being inserted between the pair of pieces 141, the mounting portion 2 causes the corner portion S to contact the contact piece 142 and the pair of pieces 141. It advances toward the one end side between a pair of pieces 141, making it slide with respect to one piece 141a. At this time, for example, when the placement portion 2, the contact piece 142, and the one piece 141a are formed of stainless steel, the placement portion 2 and the contact piece 142 slide, and the placement portion 2 and the one piece 141a. The passive film formed on the surface of the stainless steel is peeled off (scraped) by the sliding movement, and the mounting portion 2, the contact piece 142, and the one piece 141a are reliably electrically connected. In this case, dirt and crystals of the electrolytic solution L adhering to the sliding portion can be removed when sliding, so that the mounting portion 2 and the contact piece 142 and the one piece 141a are more reliably electrically connected. .

  As shown in FIG. 15 (b), the operator sufficiently pushes the mounting portion 2 against the pair of pieces 141, and then presses the fixing portion 144 against the contact piece 142 automatically or manually. And placing part 2 are brought into surface contact. By the fixing operation by the fixing portion 144, the contact piece 142 and the one piece 141a and the placement portion 2 come into contact with each other at the portions where the passive film is removed by sliding, and are surely electrically contacted. The above-described connection structure by sliding between the mounting portion 2 and the mounting portion connecting means 140 can also be adopted as a connecting structure between the anode 4 and the connecting means 120.

  Although not particularly mentioned in the above embodiment, the anode 4 may include a grip 40 as shown in FIGS. 8 and 9. Since the anode 4 includes the grip portion 40, the operator can appropriately select whether to move the anode 4 automatically or manually according to the situation.

  Although not particularly mentioned in the above embodiment, the mounting body 21 may be configured to be removable with respect to the extending portion 22. Then, the operator may fix the mounting body 21 on which the mold W is placed with respect to the extending part 22 when the mounting part 2 is raised to the non-cleaning position F. In this case, the mounting unit 2 may have an installation table for installing the mounting main body 21.
