BACKGROUND OF THE INVENTION
The present invention relates to a window molding attached to a fixed window such as a rear window of a vehicle, and a manufacturing method and a manufacturing apparatus therefor.
[0002]
[Prior art]
As a window molding attached to a fixed window such as a rear window of a vehicle, there is one in which a water collecting groove is formed in an upper portion and a cover portion is formed in a lower portion.
[0003]
  FIG. 11 is a perspective view showing a conventional window molding disclosed in, for example, Japanese Patent Laid-Open No. 4-56627. Figure11In the figure, reference numeral 1 denotes a vehicle window, which is formed by assembling a window assembly in which a window molding 3 is attached to an outer peripheral edge of a window plate 2 made of glass or the like to a vehicle body panel 5.
[0004]
In the window molding 3, the groove forming lip 12a extends from the vehicle interior side to the side flange side of the vehicle body panel in the upper portion 3u and the side portion 3s from the main body portion 11 attached to the window plate 2, thereby forming a water collecting groove. In 3l, the cover lip 12b extends from the vehicle exterior side to the vehicle body panel 5 to cover the gap between the window plate 2 and the vehicle body panel 5.
[0005]
In the above configuration, since the water collecting groove is formed by the groove forming lip 12a in the upper portion 3u and the side portion 3s, the water droplets flowing down the vehicle body panel 5 are collected in the water collecting groove and flow down to the window plate 2. The flow is prevented and the visibility is prevented. Further, in the lower part 31, the cover lip 12 b covers the gap 15 between the window plate 2 and the vehicle body panel 5 and enhances the decorativeness. The window molding 3 thus manufactured is attached to the outer peripheral edge of the window plate 2 to form a window assembly, and a liquid adhesive is applied to the outer peripheral portion of the back surface of the window assembly and is fitted into the window opening of the vehicle body panel 5. Use to cure the adhesive.
[0006]
In the conventional window molding 3, an extruded material having a groove forming lip 12a and a cover lip 12b having the same cross-sectional shape is formed over the entire length by resin extrusion, and then the upper portion 3u and the side portion 3s have groove forming lips. 12a was cut off, and the lower part 3l was manufactured by cutting off the cover lip 12b.
[0007]
As described above, the conventional window molding 3 is formed as a lip having a different shape from the groove-forming lip 12a and the cover lip 12b, and is formed by cutting out different parts, so that the lip ends near the lower corner. There was a problem that a certain cut face was exposed and the appearance was deteriorated, the decorativeness was deteriorated and the sealing property was lowered, the manufacturing process was complicated and the material loss was large. In addition, when assembling, there is a problem that a separate fixing means is required to prevent the window assembly from falling to the lower portion 3l side by its own weight until the adhesive is cured. .
[0008]
[Problems to be solved by the invention]
The problem of the present invention is that the groove-forming lip and the cover lip have a continuous and excellent appearance, are excellent in decorativeness and sealing properties, are easy to manufacture, and use no special fixing means for assembly. Also, it is to obtain a window molding that can be easily assembled by curing the adhesive in a state of being temporarily fixed by the dead weight of the window assembly.

[0011]
The window molding of the present invention is a molding that is attached to the outer peripheral edge of a window plate of a vehicle window such as a rear window, particularly a rear window, and is made of a resin extrusion molding material. This window molding is attached to the outer peripheral edge of the window plate to constitute a window assembly, and is used to construct a vehicle window by assembling it into a window opening of a vehicle body panel.
[0012]
The window molding of the present invention has a main body portion formed of a long body that engages with the outer peripheral edge of the window plate, and first and second lips made of synthetic resin that project from the main body portion toward the vehicle body panel along the longitudinal direction. Are made of an extruded material of resin integrally formed by extrusion molding. The main body portion is formed continuously and integrally so as to have a predetermined cross-sectional shape through the upper portion, both side portions, and the lower portion, and is configured to engage with the outer peripheral edge of the window plate. As the engagement structure, a structure in which a sandwiching portion is formed in the main body portion and the outer peripheral edge of the window plate is sandwiched from both the front and back sides is preferable, but other structures can be adopted for engaging the outer peripheral edge of the window plate.
[0013]
The first and second lips are integrally formed with the main body so as to protrude from the main body toward the body panel side, that is, the side opposite to the window plate. The first lip is formed by moving its position by extrusion so that its protruding position is different from that of the main body, so that the groove-forming lip and cover lip protruding from different positions of the main body have different positions. It is formed to be continuous in the direction. The second lip is formed so as to be integrated with the main body portion in the lower portion and not to exist in the upper portion.
[0014]
That is, the first lip forms a groove-forming lip that extends from the vehicle interior of the main body to the side flange of the vehicle body panel to form a water collecting groove at the upper portion, and the lower portion from the vehicle exterior to the outer surface side of the vehicle body panel. A cover lip is formed so as to cover the gap between the window plate and the vehicle body panel, and these are formed so as to continuously change in a region from the upper corner side of the upper portion to the lower corner side of the lower portion. The second lip is formed so as to be in contact with the side flange of the vehicle body panel from the vehicle inner side of the main body portion in the lower portion so as to press the window plate toward the upper side and not to exist in the upper portion. .
[0015]
Like the upper part, the side lip is preferably a groove-forming lip. In this case, the protruding position changes near the lower corner part and the lower part changes to a cover lip. The protruding position may change near the upper corner portion, and a cover lip may be formed on the side portion. The second lip is not formed when the first lip is a groove-forming lip at the side portion, but the second lip is preferably formed when the first lip is a cover lip at the side portion.
[0016]
The window molding is made of an extruded product of resin (including rubber), but may be combined with other materials. In particular, when the core part is integrated with a stretch-resistant core material in the longitudinal direction, it is excellent in dimensional stability during use, and the extrusion amount of the extrusion molding material or the core material in a state in which the longitudinal stretch is prevented during production. This is preferable because the delivery amount can be accurately detected and the movable type operation can be accurately controlled based on the detected value so that the lip can be accurately formed. Such a core material is preferably a linear or plate-like material, but a hard material such as a metal deformed material can also be used. In the case of this metal deformed material, the core material is exposed on the surface to provide a decorative surface. Can be formed.
[0017]
The main body portion is preferably formed to have the same cross-sectional shape throughout the entire length, but in some cases, shaping may be performed in a subsequent process so that the cross-sectional shape changes in part. Similarly, the groove lip and cover lip of the first lip, or these and the second lip can be formed in substantially the same cross-sectional shape, but the cross-sectional shape can be changed in a subsequent shaping step. You can also. In this case, it is preferable to shape the first lip so that the groove-forming lip of the first lip and the tip of the second lip are curved outward in the shaping step.
[0018]
The window molding as described above has a fixed mold having a fixed orifice for extruding the main body, and first and second movable orifices for extruding the first and second lips to be integrated with the main body. It can be manufactured by an extrusion mold including a movable mold and a drive device that moves the movable mold to integrate the first and second lips at a predetermined position of the main body.
[0019]
In the drive device, the first lip extends from the vehicle interior of the main body to the side flange of the vehicle body panel at the upper portion to form a groove-forming lip, and the lower portion extends from the vehicle exterior to the outer surface of the vehicle body panel. A cover lip is formed, and the second lip is integrated with the inner side of the main body at the lower portion, and the movable mold can be moved so as not to be integrated with the upper portion. In this case, it is preferable to have a control device that detects the feed amount of the core material into the extrusion mold or the extrusion amount and movement amount of the extrusion molding material as a substitute value of the extrusion length, and controls the driving device based on this detection. .
[0020]
The movable type is configured to be movable adjacent to the fixed type, and is preferably configured to rotate about the resin connection ports for forming the first and second lips. In this case, the driving device Is configured to move the movable orifice by rotating the movable mold, but the movable mold may be configured to reciprocate linearly, for example.
[0021]
In the case of a rotary type, it is preferable that the rotary mold is rotated and reciprocated around the communication port of the resin flow path. In the case of the linear reciprocating motion type, it is preferable to provide a long hole-like communication port in the fixed mold so as to communicate in a region where the movable first and second movable orifices move. In any case, both the first and second lips are integrated with the main body portion in the lower portion, but the second lip is extruded so that only the first lip is integrated with the upper portion. It is preferable that the movable orifice moves so as to deviate from the opening position of the fixed orifice that pushes out the main body.
[0022]
When the core material is integrated with the main body, a core material supply device that supplies a stretch-resistant core material to the fixed orifice of the fixed mold is provided upstream of the extrusion mold. In order to deform the extruded first and second lips, a shaping device is provided downstream of the extrusion mold.
[0023]
In order to manufacture the window molding by the manufacturing apparatus as described above, the main body portion having a predetermined cross-sectional shape is extruded from the fixed orifice provided in the fixed mold of the extrusion mold, and the first provided in the movable mold. The first and second lips having a predetermined cross-sectional shape are extruded from the second movable orifice, and the position of the first lip with respect to the main body is determined by the drive device from the vehicle interior side of the main body to the side of the vehicle body panel. It extends to the flange side to form a groove-forming lip, the lower part extends from the outside of the vehicle to the outer surface of the vehicle body panel to form a cover lip, and the second lip is integrated with the inner side of the main body at the lower part. By moving the movable mold so that it is not integrated in the upper part, and integrating the extruded first and second lips with the main body part, The production of packaging.
[0024]
When a linear core material having stretch resistance is integrated, the core material is continuously supplied from the core material supply device and the main body portion is extruded. When a metal profile is used as the core material, the profile is supplied to the fixed mold to form the main body, and the first and second lips are integrated therewith. When the movable type is a rotary type, the first and second lips are integrated by rotating the first movable orifice and the second movable orifice by the driving device.
[0025]
The resin that forms the main body and the resin that forms the first and second lips may be the same or different. However, if they are different, they may have different physical properties such as hardness, creep resistance, and elastic modulus. It is preferable to use a resin having solubility. As such a synthetic resin, generally, the main body portion is preferably a semi-rigid resin, for example, a semi-rigid PVC resin, in order to increase the mounting stability, and the first and second lips are buffering, sealing, In order to increase the resistance to damage to the vehicle body panel, a soft and highly creep-resistant resin such as a flexible PVC resin or TPE resin (thermoplastic elastomer resin) having elasticity is preferable.
[0026]
In order to deform the first and second lips, after the first and second lips are extruded, the front end of the first lip is formed at the upper portion and the second lip is formed at the lower portion by the shaping device. Is shaped to curve toward the outside of the car. About a main-body part and a 1st lip, you may shape so that a cross-sectional shape may change partially by cutting etc. with a lip.
[0027]
The above window molding attaches the body part to the outer periphery of the window plate to form a window assembly, applies a liquid adhesive to the outer periphery of the back surface of the window assembly, and fits it into the window opening of the body panel. When the window assembly is assembled, the second lip formed on the lower part presses the side flange of the vehicle body panel and presses the window plate upward as a reaction. Thus, the adhesive can be cured by temporarily fixing the window assembly in place, so that no special means for temporarily fixing the window assembly is required. Further, when the groove forming lip and the second lip are curved, the assembly and the groove formation and pressing by this are facilitated.
[0028]
【The invention's effect】
  The window molding of the present invention isIn the window molding attached to the window plate of the window assembly to be assembled in the window assembly fitting recess formed in the window opening of the vehicle body panel,The first lip protruding from the main body isForm a catchment ditchIt becomes a groove forming lip,By changing the protruding position and shape continuously in the region from the upper corner side of the upper part to the lower corner side of the lower part,In the lower partExtends from the vehicle exterior of the main body to the outer surface of the vehicle body panel to cover the gap between the window plate and the vehicle body panelWith cover lipBecomeIn this way, the upper part is extruded integrally, so that the upper part can form a water collecting groove to prevent water droplets on the vehicle body panel (roof panel) from flowing to the window plate and cover the gap in the lower part. In this case, the groove forming lip and the cover lip have a continuously excellent appearance, and a window molding that is excellent in decoration and sealing properties and easy to manufacture can be obtained. Also, the second lip is the lower part of the body partThan the cover lip formed by the first lipIt is formed on the inside of the car and elastically contacts the side flange of the vehicle body panel. It is not formed on the upper part, so it is easy to harden the adhesive by temporarily fixing it while preventing the window assembly from slipping off during assembly. become.
[0029]
When the main body has a stretch-resistant core material, the dimensional stability during use is enhanced, and the amount of extrusion molding material or the amount of core material supplied is accurately measured during production to operate the movable mold. It becomes easy to accurately control and form the protruding positions of the first and second lips at an accurate position, and a molding in which the first and second lips accurately change at a predetermined position can be obtained. A groove-forming lip and a cover lip having substantially the same cross-sectional shape can be easily manufactured by simply changing the protruding position of the lip from the main body. Further, the groove-forming lip and the tip of the second lip shaped so as to bend toward the outer surface side are easy to form a groove, press and attach the vehicle body panel to a predetermined position. The groove can be formed and the window assembly can be temporarily fixed at a predetermined position.
[0030]
In the method of manufacturing a window molding according to the present invention, the first and second lips can be moved by moving the movable mold by the driving device while extruding the main body portion from the extrusion shaping fixed mold and extruding the first and second lips from the movable mold. Therefore, the above-mentioned window molding in which the projecting positions of the first and second lips continuously change can be easily manufactured by a simple device and operation.
[0031]
In this case, by integrating the stretch-resistant core material and extruding the main body, the extrusion amount of the extrusion molding material or the feeding amount of the core material can be accurately measured in a state where the expansion and contraction of the extrusion molding material is prevented. It is possible to accurately control the operation of the movable mold to accurately form the protruding positions of the first and second lips, and to manufacture a molding having high dimensional stability during use. When a metal profile is used as the core material, the metal profile can be formed from the metal profile to obtain a highly decorative molding.
[0032]
When a resin that is compatible with the resin that forms the main body and the resin that forms the first and second lips is used, the two are welded together, so the adhesiveness is high, and molding is possible even without special bonding treatment. Can be manufactured.
When shaping is performed after the first and second lips are extruded, a molding in which the tips of the groove-forming lip and the second lip curve outward can be easily manufactured by shaping.
[0033]
Since the manufacturing apparatus of the present invention includes the extrusion mold having the fixed mold and the movable mold and the driving apparatus, the window molding can be efficiently manufactured with a simple structure and operation.
[0034]
In the case of using a rotary reciprocating type as the movable type, it can be rotated around the resin flow paths for forming the first and second lips, so that the movable type slide is compared with the case of the linear reciprocating type. It is possible to facilitate the manufacture by reducing the resin leakage at the moving part and moving the movable mold smoothly. On the other hand, in the case of the linear reciprocating motion type, for example, it is possible to move in the moving direction which is difficult with the rotary movable type, such as the linear direction, and the restriction on the formation of the main body portion is reduced.
[0035]
When a core material supply device is provided, a stretch-resistant core material can be supplied to the fixed orifice and integrated. In this case, the supply amount of the core material is measured, and the substitute value of the extrusion amount of the extrusion molding material. As a result, the manufacturing process can be controlled.

Although the end portion (joining portion) 3e in the longitudinal direction is arranged at 3l, an end portion 3e ′ may be provided in the upper portion 3u instead of this position. This window molding 3 is preferably used through the upper part 3u, the side part 3s, and the lower part 3l. However, the other part, for example, a corner part is notched so that the axis can be bent easily. May be.
[0039]
The window molding 3 is made of an extrusion molding material of resin, and engages so that the outer peripheral edge of the window plate 2 is sandwiched from both the front and back sides, and first and second extending from the main body 11 to the vehicle body panel 5 side. The lips 12 and 13 are integrally formed, and are integrally formed continuously by extrusion through the upper portion 3u, the side portion 3s, and the lower portion 3l.
[0040]
  The main body 11 is embedded with a deformable elongated core material 14 which is stretch-resistant in the longitudinal direction at a fixed position of the main body 11 over the entire length, and is substantially in the same U-shaped cross section through the upper portion 3u, the side portion 3s and the lower portion 3l. It has an insertion groove 15 and a guide surface 16 which are formed in a shape and into which the outer peripheral edge of the window plate 2 is inserted, and an arcuate surface 17 is formed on the vehicle body panel side.

Further, such a core material is preferably provided at or near the neutral line of bending when the window molding is bent and attached with a predetermined radius of curvature later.
[0041]
The first and second lips 12 and 13 are integrally formed with the main body 11 so as to protrude from the arcuate surface 17 of the main body 11 along the longitudinal direction toward the body panel 5 side, that is, toward the side opposite to the window plate 2. Has been. The first lip 12 is formed by moving the position of the first lip 12 by extrusion molding so that the protruding position thereof differs from the main body portion 11, so that the groove forming lip 12 a and the cover lip 12 b protruding from different positions are long. It is formed so as to be continuous along the direction. The second lip 13 is integrated with the inner side of the vehicle body 11 in the lower portion 3l and is formed so as not to exist in the upper portion 3u.
[0042]
That is, the first lip 12 is formed at the upper portion 3u and the side portion 3s to form a water collecting groove 19 extending from the position on the inner side of the arcuate surface 17 of the main body portion 11 toward the side flange 5a of the vehicle body panel 5. A lip 12a is formed, and a lower portion 3l is formed with a cover lip 12b extending from the outer side position of the arcuate surface 17 to the outer surface side of the vehicle body panel 5 and covering the gap 20 between the window plate 2 and the vehicle body panel 5. The groove forming lip 12a and the cover lip 12b are formed so as to continuously and smoothly change in the vicinity of the lower corner portion 3cl. The second lip 13 extends in parallel with the cover lip 12b so as to abut against and press against the side flange 5a of the vehicle body panel 5 from the vehicle inner side of the main body 11 at the lower part 3l, and exists at the upper part 3u and the side part 3s. It ’s gone.
[0043]
The main body 11 is formed in the same cross-sectional shape over the entire length, but the cross-sectional shape may be changed depending on circumstances. The first lip 12 has substantially the same basic cross-sectional shape, but the tip of the groove forming lip 12a of the upper portion 3u and the side portion 3s is on the outside of the vehicle as shown by a chain line 12a '. It is deformed so as to curve toward The second lip 13 is formed only in the lower portion 3l and is deformed so that the tip thereof is curved toward the vehicle outer side as indicated by 13 'in a free state.
[0044]
The window molding is formed in an annular shape by joining the end portions 3e in advance, and the annular window molding 3 is attached to the outer peripheral edge of the window plate 2 on which the opaque print layer 9 is previously formed and the dam rubber 10 is fixed. An assembly 4 is formed. In this case, it is preferable that an adhesive or a double-sided adhesive tape is interposed in the insertion groove 15 of the window molding 3 and the outer peripheral edge of the window plate 2 is inserted and fixed, but this is not always necessary. At this time, the opening-shaped guide surface 16 facilitates the insertion and engagement of the window plate 2 and the window plate 2.
[0045]
With the window assembly 4 thus manufactured, the liquid adhesive 7 is continuously discharged in a string shape between the dam rubber 10 and the main body 11 of the window molding 3, the window opening 6 of the vehicle body panel 5 is opened. The vehicle is fitted into the window assembly insertion recess 8 so as to be shielded, and the adhesive 7 interposed between the window assembly 4 and the side flange 5a and the bottom flange 5b of the vehicle body panel 5 is cured and fixed. The window 1 for manufacture is manufactured.

In the lower part 31, the cover lip 12 b is brought into contact with the outer surface of the vehicle body panel 5 to cover the gap 20. Since the tip of the groove forming lip 12a is curved outward, it is easy to form the water collecting groove 19, and the water collecting groove once formed easily maintains its groove shape.
[0048]
In the window molding 3, the first lip 12 protruding from the main body 11 is a groove-forming lip 12a in the upper part 3u and the side part 3s, and a cover lip 12b in the lower part 3l, which changes continuously and smoothly. Since the main body 11 is integrally formed with the extrusion, the water collecting groove 19 is formed in the upper portion 3u and the side portion 3s so that water droplets on the vehicle body panel (loop panel) 5 flow to the window plate 2. It can be prevented and disappears smoothly before the water collecting groove 19 reaches the lower portion 31, and the lower portion 3 l can cover the gap 20 and enhance the decorativeness. In this case, since the groove-forming lip 12a and the cover lip 12b are continuous, a window molding having an excellent appearance, excellent decorativeness and sealing property, and easy to manufacture can be obtained.
[0049]
In addition, since the main body 11 has the stretch-resistant core material 14, the dimensional stability during use is increased, and the amount of the core material supplied is measured as an alternative to the measurement and detection of the extrusion amount at the time of manufacture. It is easy to accurately control the position of the lips 12 and 13 so that the protruding positions of the lips 12 and 13 can be accurately formed, and the molding 3 in which the first and second lips 12 and 13 change at a predetermined position is obtained. Since the groove-forming lip 12a and the cover lip 12b are formed in substantially the same cross-sectional shape, they can be easily manufactured only by changing the protruding positions of the first and second lips 12,13. Moreover, since the tip portions of the groove forming lip 12a and the second lip 13 are shaped so as to bend toward the vehicle exterior, groove formation and assembly are easy, and the window assembly is assembled at a predetermined position. Thus, the water collecting groove 19 having a predetermined shape can be formed.
[0050]
In the above-described embodiment, the example in which the window molding is attached in advance to the outer peripheral edge of the window plate and then attached to a predetermined position of the vehicle body panel has been described, but instead of this, it can be engaged by elastic deformation by insertion. It is also possible to use a window molding having a hook-shaped engaging portion, and attach the window molding by inserting the window molding into the gap between the outer peripheral edge of the window plate and the vehicle body panel after the window plate is attached to the vehicle body panel.

A convex rotary joint 35a is formed around the communication port 34a of the fixed mold 24a. The resin flow path 32cContactIt is preferable from the viewpoint of preventing resin leakage that the flow path is closed in a pipe shape between 34b and the movable orifice 33b.
[0054]
The movable mold 24b is formed in a disk shape, and a concave rotary joint portion 35b is formed around the communication port 34b to engage with the fixed convex rotary joint portion 35a. The rotary shaft 35b is reciprocally rotated along the guides 36a and 36b with the rotation axis 35b as a rotation axis. 34c is a sealing material for preventing resin leakage, and heat-resistant polyimide resin or the like is used. First and second movable orifices 33b and 33c for extruding the first and second lips 12 and 13 are provided at positions on the circumferential portion of the movable mold 24b facing the fixed orifice 33a, respectively. The resin in the resin flow paths 32 d and 32 e branched from the resin is extruded and integrated with the main body 11. A worm wheel gear 37 is formed on the opposite circumferential portion of the movable die 24b and meshes with a worm 38. The worm 38 is supported by a bearing 39a, and is preferably an AC servo motor or the like in terms of ease of control and accuracy. The drive device 40 is connected so as to rotate via a drive shaft 40a.
[0055]

And it has the shaping cutting part 26b which cut | disconnects the 2nd lip | rip 13, and the discharge port 26c which discharges | emits the cut | disconnected 2nd lip | rip 13.
[0056]
As shown in FIG. 5, the manufacturing method of the window molding 3 continuously feeds the core material 14 from the uncoiler 21 through the pinch roll 22, and the amount of delivery is detected by the detection device 23 of a delivery amount detection sensor such as a rotary encoder. It supplies to the core material holder 24c of the extrusion mold 24, detecting. When integrating the decorative strip 18, the decorative strip 18 is fed from the uncoiler 21 a and supplied to the extrusion mold 25. The detection signal 42 of the detection device 23 is input to the control device 31. Instead of detecting the delivery amount of the core material 14 as in this embodiment, the detection is performed by directly detecting the extrusion amount of the extrusion molding material 41 described later at the position of the extrusion mold 24 or downstream of the take-up machine 28. A device 23a or 23b may be provided.
[0057]
In the extrusion mold 24, a relatively hard resin, for example, a semi-rigid polyvinyl chloride resin, is supplied from the resin supply path 25a as the resin 42a for forming the main body portion 11, and the fixed orifice 33a is passed through the resin flow path 32a of the fixed mold 24a. The body part 11 is formed integrally with the core member 14 by extrusion. Further, the resin 42b for forming the first and second lips 12 and 13 from the resin supply path 25b is an elastomer such as a chlorinated ethylene copolymer which is rich in elasticity, has high clip resistance and is relatively soft and compatible with the resin. Resin is supplied and extruded from the first and second movable orifices 33b, 33c of the movable mold 24b through the resin flow path 32b of the fixed mold 24a and the resin flow paths 32c, 32d, 32e of the movable mold 24b, and the first and second 6 are formed and fused and integrated with the main body 11, and the extruded material 41 having a cross-sectional shape shown in FIG.
[0058]
In this case, the detection signal 42 of the detection device 23 is sent to the control device 31, the drive signal 43 is sent from the control device 31 to the drive device 40, and the drive device 40 is moved at a predetermined rotation speed for a predetermined time for a predetermined rotation speed. The worm 38 is rotated to rotate, and thereby the extrusion is performed while the movable die 24b is reciprocally rotated in the R and S directions via the worm wheel gear 37. When forming the lower part 3l of the window molding 3, the movable mold 24b is rotated in the R direction and stopped at the position indicated by the solid line in FIG. 6, and extrusion molding is performed in this state. As a result, the first lip 12 pushed out from the first movable orifice 33b of the movable mold 24b is integrated so as to protrude from the vehicle exterior side of the main body portion 11 to form the cover lip 12b. Further, after the second lip 13 is pushed out from the second movable orifice 33c, the tip end portion is curved outward by the shaping / cutting portion 26b while passing through the shaping device 26.
[0059]
In the case of forming the upper portion 3u and the side portion 3s, the drive signal 43 is sent from the control device 31 to the drive device 40 at the time when the extrusion of the extruded material 41 proceeds and the lower corner portion 3cl is formed. And thereby the movable mold 24b is rotated in the S direction to move the movable orifice 33b to the position 33c. As a result, when the second movable orifice 33c reaches a position 33d that intersects the shaped cutting portion 26b, the second movable orifice 33c starts to be gradually cut from the tip of the second lip 13 to be extruded, and is discharged as the discharged resin 43 from the discharge port 26c. When rotated, the entire second lip 13 is disengaged from the position facing the main body 11 and is discharged from the discharge port 26c as the discharged resin 43, and the second lip 13 does not exist. Finally, the resin flow path 32c moves to the position of the chain line 32f, and the second movable orifice 33c moves to the position of the chain line 33e.
[0060]
The first lip 12 pushed out from the first movable orifice 33b moves to the position of the second lip 13 in FIG. As a result, the protruding position of the first lip 12 that is pushed out from the main body portion 11 changes, and a groove-forming lip 12 a that protrudes from the vehicle inner side of the main body portion 11 is formed.
The groove-forming lip 12a thus formed passes through the shaping device 26 as the upper portion 3u and the side portion 3s are pushed out. At this time, since the main body 11 is sent out over the support 26a, the cross-sectional shape does not change, but the lip 12b passes over the shaped cutting part 26b having a curved concave surface, so that the tip is directed to the outside of the vehicle. And deform.
[0061]
When the extrusion of the extruded material 41 further proceeds and the next lower corner portion 3cl is formed, the drive signal 43 is sent again from the control device 31 to the drive device 40, and the drive device 40 is rotated to move the extrusion molding material 41. The mold 24b is rotated in the R direction to form the side portion 3s and the upper portion 3u. In this way, the extruded material 41 in which the molding 3 shown in FIG. 4 is continuous is formed. A broken line 12c in FIG. 4 shows an example in which the position of the lip 12 is changed near the upper portions on both sides.
[0062]
The extrusion molding material 41 thus molded is cooled and cured by the cooling device 27, taken by the take-up machine 28, and then cut by the cutting machine 29 to manufacture the window molding 3. The cutting position is 3e shown in FIGS. 1 and 4, that is, a position corresponding to the middle part of the lower part 3l, but may be a position corresponding to 3e ', that is, a middle part of the upper part 3u depending on circumstances.
[0063]
Cutting of the extrusion molding material 41 is performed by inputting a cutting signal 44 from the control device 31 to the cutting machine 29 based on the detection signal 42 of the detection device 23 (or 23a, 23b). In this case, the movable die 24b is calculated from the distance of the cutting machine 29 and the extrusion speed of the core material 14 or the extrusion molding material 41 to calculate the time point when the scheduled cutting position reaches the position of the cutting blade of the cutting machine 29, and the cutting signal 44 is output. When the position and speed of the extrusion molding material 41 are detected by the detection device 23b, the cutting time point is calculated from the distance between the detection device 23b and the cutting machine 29 and the speed of the extrusion molding material 41. As the detection devices 23a and 23b, an infrared sensor or the like that detects the position of the lip 11 is used. As the cutting machine 29, a traveling cutting machine that travels and cuts at the same speed as the extrusion speed of the extrusion molding material 41 is used.
[0064]
In the above-described embodiment, the case where the resin discharge ports 26c and 33d are provided has been described. However, the resin discharge port is not always necessary, and the orifice 33c that forms the second lip 13 is blocked. You may do it. In this case, the amount of resin supplied to the orifice 33c that forms the second lip 13 is controlled to increase or decrease in accordance with the opening and closing of the orifice. Such control can be achieved by increasing / decreasing the number of rotations of an extruder (not shown).
[0065]
8 and 9 show an extrusion mold in a different state of another embodiment, in which (a) is a view taken along the line E-E of FIG. 5 and (b) is a cross-sectional view thereof taken along HH. In this embodiment, the fixed mold 24a of the extrusion mold 24 is configured in substantially the same manner as in the previous embodiment, but the movable mold 24b is configured to reciprocate linearly.

  The basic operation of the window molding manufacturing method by this apparatus is the same as that of the above embodiment, but the first and second by the movable mold 24b.NoThe tops 12 and 13 are formed by causing the drive unit 40 to reciprocate the movable die 24b via the drive shaft 40a. At this time, when the resin 42b is supplied from the resin flow path 32b with the movable mold 24b moved in the X direction as shown in FIG. 8, a part of the resin 42b is pushed out from the first movable orifice 33b through the resin flow path 32d. One lip 12 (cover lip 12b) is formed, and another part of the resin is extruded from the movable orifice 33c through the resin flow path 32e to form the second lip 13, which is formed by the shaping portion 26d of the shaping die 26. The tip is curved.
[0068]
When the extrusion of the extrusion molding material 41 proceeds and the lower corner portion 3cl is molded, when the movable mold 24b starts to move in the Y direction by the driving device 40, the resin flow path 32e extends from the front end side of the resin flow path 32b. The second lip 13 that moves outward and is pushed out from the second movable orifice 33 is gradually not formed. Instead, the discharge port 33d starts to coincide with the resin flow path 32b, and excess resin is discharged as the discharged resin 43. The state in which the movable mold 24b is moved in the Y direction is shown in FIG. 9, and a part of the resin in the resin flow path 32b is extruded by the resin flow path 32d to form the first lip 12 (groove forming lip 12a). The tip is bent by the shaping mold 26. The other resin is discharged from the discharge port 33d as the discharged resin 43.
[0069]
FIG. 10 shows still another embodiment. The window molding 3 uses a metal profile 11a as the core material 14, and supplies the metal profile 11a to a fixed mold of an extrusion mold to extrude the resin portion 11b. The main body 11 is formed by molding, and the first and second lips 12 and 13 are extruded from the movable mold. The first lip 12 forms a groove-forming lip 12a and a cover lip 12b. It manufactures by integrating with 11 metal profile 11a. Further, the end portions in the longitudinal direction are attached to the window plate and then connected by a separate cover and connecting member.
[0070]
