Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pouring device for casting.

BACKGROUND ART Conventionally, continuous pouring devices for relatively small ingots, such as ingot casting, have been known. In this method, molds with flat tops and open upwards are continuously arranged, the bottom of a pouring block is brought into close contact with the top of the molds, and the molds are moved while pouring the metal. Therefore, this conventional method could only be used for molds that had a shape that made it easy to remove the ingot and were made of a material that could withstand the close sliding of blocks.

The present invention was made in view of these points,
The purpose is to enable continuous and efficient pouring of molten metal from a ladle or the like into molds of various shapes and materials while flowing down.

Next, one embodiment of the present invention will be described based on FIGS. 1 to 4.

Two rows of endless chains 1 are arranged at parallel intervals, both ends of the two rows of chains 1 are supported by sprocket foils 2, and one of the sprocket wheels 2 is connected to a drive shaft 3. The other is supported by the driven shaft 4.

The inner link pieces of the two rows of endless chains 1 are formed by alternately attaching the convex pieces 6 on both sides of the funnel attachment base 5 and the distribution part attachment pieces 7, and are integrally attached to the two rows of endless chains 1. A funnel 8 serving as a molten metal collector is fixed to the center of the funnel attachment base 5 incorporated in the funnel, and the funnel 8 as a molten metal collector is bridged over the distribution part attachment pieces 7 on both sides to distribute the lower parts of both sides of the mountain-shaped molten metal distribution part 9. An endless moving body 11 is formed by fixing the portion 9 so as to protrude inside the endless circuit.

The molten metal distribution section 9 has V-shaped grooves 12 and 13 as concave portions formed on the slopes on both front and rear sides in the direction of movement, and a V-shaped branch portion 14 as a concave notch at the upper end of the V-shaped grooves 12 and 13. Each distribution part 9 is fixed to the distribution part attachment piece 7 so that a substantially diamond-shaped molten metal outlet 15 is provided between the lower ends of the V-shaped grooves 12 and 13 of the front and rear distribution parts 9. The molten metal dropping part 15 is located directly below the funnel 8.

Also, each tooth 21 of the sprocket foil 2
are inserted one after another between the connecting pins 22 at both ends of the distribution part attachment piece 7, and the pressed part 23 is inserted from both sides of the funnel attachment base 5.
is integrally provided in a protruding manner, and a presser rail 24 provided along the lower moving portion of the endless moving body 11 is brought into contact with the upper surface of this pressed portion 23 . This presser rail 24 is fixedly provided at a certain level by supporting parts 25 and mounting screws 26 on both sides, and the above-mentioned mounting base 5 and funnel 8 are fixedly provided by this presser rail 24.
The lower end of the funnel 8 prevents the core inside the mold from lifting up during pouring.

Further, the endless moving body 1 is formed by the endless chain 1 and the endlessly arranged molten metal distribution section 9.
A ladle 31 is provided at a fixed position above the lower moving part 1. This ladle 31 is supported so as to be tiltable about a support shaft (not shown), and the molten metal inside is distributed from the tap port 32 by tilting the tap port 32, which is the molten metal outflow portion, downward at a constant speed. Part 9
let it flow upwards.

Further, a mold conveyance line 41 is provided below the endless moving body 11 and moves in synchronization with the molten metal dropping port 15. That is, a plurality of transport bases 43 are movably provided with respect to fixed rails 42 at a certain level,
A plurality of molds 44 are arranged and fixed at equal intervals on this conveyance base 43, an elevator mechanism 45 for carrying in or out the conveyance base 43 of the molds 44 is provided at both ends of the fixed rail 42, and the endless moving body The eleven drive shafts 3 and the conveyance base 43 are driven synchronously by the same drive source. Note that each transfer base 43 is continuously driven to transfer using a fluid pressure cylinder, a chain, or the like.

Then, when the ladle 31 is gradually tilted while the endless moving body 11 and the mold conveyance line 41 are driven synchronously, the molten metal flowing out from the ladle 31 in the fixed position to the fixed position is transferred to the molten metal distribution section 9. moves, so the falling position of the molten metal is determined by the molten metal distribution section 9.
The molten metal moves from the V-shaped groove 12 at the front to the V-shaped groove 13 at the rear via the branch part 14, and the molten metal that falls into the V-shaped groove 12 at the front passes through the molten metal drop opening 15 at the front and the funnel 8, and then flows below the funnel 8. The molten metal is poured into the mold 44 which is moving synchronously, and the molten metal is instantly cut by the branch part 14 and falls into the V-shaped groove 13 at the rear, passes through the molten metal drop port 15 at the rear and the funnel 8, and then flows into the funnel. 8
The metal is poured into the mold 44 below. Furthermore, the molten metal falls directly into the drop port 15 at the lower end of the V-shaped groove 13, and then falls into the opposing V-shaped groove 12, and then drops into the same drop port 1.
5 into the funnel 8 above.

In this way, from the branch part 14 of the molten metal distribution part 9 at the front to the branch part 14 of the molten metal distribution part 9 at the rear.
When the ladle 31 passes directly below the tap 32 of the ladle 31, the molten metal is poured into the mold 44 below through the molten metal drop 15 and the funnel 8 between the branch parts 14. In order to adjust the amount of molten metal poured, it is necessary to change the moving speed of the endless moving body 11 and the mold conveyance line 41, change the tilting speed of the ladle 31, or change the interval between each molten metal distribution section 9. Just do it. In particular, by adjusting the interval of the final molten metal distribution section 9, it is possible to continuously pour molten metal into molds of various capacities.

In addition, although the above embodiment has explained the vertical endless moving body 11, another embodiment of the present invention will be explained in the fifth embodiment.
This will be explained based on FIGS. 7 to 7.

A ladle 51 is provided at a fixed position, and a plurality of mountain-shaped molten metal distribution parts 52 with scalene triangular cross sections are arranged in an endless manner below the ladle 51 via a molten metal drop port 53. The body 54 is provided horizontally,
The molten metal dropping port 53 is located below this endless moving body 54.
A mold conveyance line 55 that moves in synchronization with the mold transport line 55 is provided in a folded manner along the semicircular portion of the endless moving body 54.

The ladle 51 is placed in a fixed position facing in the direction opposite to the moving direction of the endless moving body 54, and the tap hole 55, which is the molten metal outlet, is connected to the molten metal distribution part 52.
Each of the molten metal distributing parts 52 has a recess 61 having a gentle slope 57 and steep slopes 58 and 59 on both sides of the gentle slope 57 and opposite sides of the endless moving body 54. A branch 62 as a recessed notch is formed between the upper end of the gentle slope 57 and the upper end of the steep slope 59 by continuously drilling inside.

Further, the mold conveyance line 55 is connected to the support frames 6 on both sides.
Each conveyance base 65 is movably supported by rollers 64 provided at 3, and each conveyance base 65 is
are sequentially connected with pins 66 and forcibly transferred through a part of the line 55, and two molds 6 are connected with one transfer base 65.
I support 7. The spacing between the molds 67 is set to the spacing between the molten metal drop ports 53, and both are connected to the endless moving body 5.
Match at the semicircular part of 4. Note that below each of the molten metal drop ports 53, a funnel 68 as a molten metal collector is provided integrally with the endless moving body 54.

Then, when the endless moving body 54 and the mold conveying line 55 are driven at the same speed in synchronization and the ladle 51 in the fixed position is tilted, the molten metal flowing down from the outlet 56 of the ladle 51 is It sequentially falls from the steep slope 59 to the gentle slope 57 via the branch 62. The molten metal that has fallen onto the steep slope 59 in front passes from the droplet 53 in the front, through the funnel 68 in the front, and into the mold 6 in the front.
The molten metal poured into the ladle 7 and then flowing down from the ladle 51 is cut by the branch part 62 and instantly switched to the rear gentle slope 57, passes through the rear drop opening 53 and the funnel 68, and then flows into the rear mold 67. The hot water is poured into the water.
The molten metal is then supplied to the recess 61 on the rear drop port 53 until it is cut by the next branch 62.

Note that if the volume of each of the recesses 61 is formed in accordance with the corresponding mold 67, continuous pouring of mixed molds of different sizes can be performed.

Also, as shown in FIG. 8, rollers 7 on both sides
1 to support the conveyance base 65, and a mold conveyance line 74 in which a roller 72 rotatably provided on the lower surface of the conveyance base 65 is guided by fixed guides 73 on both sides of the roller 72 may be used.

As described above, according to the present invention, an endless moving body in which mountain-shaped molten metal distribution parts and molten metal collectors are arranged alternately is provided below the molten metal outflow part, and the molten metal collecting unit is arranged below the endless moving body. Since a mold conveyance line that moves in synchronization with the mold is provided, it is possible to switch and pour molten metal, which is continuously flowing down from a ladle, etc., into each mold conveyed by this line one after another. The ladle can continue discharging molten metal until it is empty, which is extremely efficient compared to the conventional method of pouring molten metal into each mold by tilting the ladle each time, and this reduces the temperature of the molten metal in the ladle. There are few
There is no deterioration in quality of castings due to temperature drop. Furthermore, unlike the conventional continuous pouring device in which a plurality of molds are arranged in succession and the bottom of the pouring block is brought into close contact with the top surface of the mold and the pouring is carried out while moving, the present invention uses a plurality of ridge-shaped molds. The molten metal collector, which is an endless moving body having a molten metal distribution section, is moved in synchronization with the mold conveyance line, eliminating the risk of interference such as rubbing from other members to the mold conveyed by the line. The mold can be of any type, including metal molds, sand molds, shell molds, etc., and the material of the mold is not limited, and each mold can be provided separately and independently, so it is not possible to use conventional continuous pouring. It is not necessary to have a flat upper surface and to arrange the molds continuously, as in a hot water device, and it can be used for molds of various shapes. In addition, the amount of molten metal poured into the mold can be determined by the interval between the molten metal distribution parts of the endless moving body and the moving speed of the endless moving body without having to tilt the ladle for each mold. It is easy to make accurate and is effective for pouring into molds of medium size or smaller. Furthermore, since the endless moving body can be circulated and used repeatedly, the installation area of the device can be used effectively.

In particular, in the present invention, since the concave notch is provided at the upper end of the molten metal distribution part, the molten metal can be instantly switched from one side slope to the other side slope by this notch, and the molten metal at the upper end of the slope can be This prevents the leakage from spreading to areas other than the slopes on both sides. Also,
The concave part provided on the slope allows the molten metal that flows down the slope to be kept in the center of the slope, and also to prevent the molten metal from being poured into the wrong position due to sudden changes in the molten metal flow angle when distributing the molten metal.
The molten metal collecting device allows the molten metal to be guided to the correct pouring position. Therefore, the top surface of the mold is not flat,
And it doesn't have to be wide open, and
There is no need to seal or shield the gaps between mold joints. For this reason, the pouring device of the present invention has the excellent effect of being able to easily pour metal into foundry molds other than ingot molds.
