There is a sprue and riser part (not shown) in the split surface of mold A, and the mold at the bottom can be removed so that the molten metal just flows into the sprue and riser part according to the reversal operation of the bathtub. It is provided in Therefore, after pouring an amount of molten metal corresponding to the casting of the product into the bath, the motor 60 is driven to drive the chain 63 via the sprocket 61, chain 62, sprocket 59, shaft 57, and sprocket 56. 52 in Figure 6b
When rotated 90 degrees clockwise from the state, mold A
Molten metal can be poured into the mold from a bathtub.

After pouring the metal into the mold A, the motor 60 is reversed to reverse the wheel 52 and return it to its original position. I'll keep it. When the wheel body 52 returns to its original position, the embossing plate 79 is moved to the cylinder 78.
The mold A is raised by the above operation, and the mold A can be transferred.

The mold A that has been poured is transferred to the first line L ₁ of the first conveying device E by the first extrusion device B described above.

When moving on _L1 , the mold A placed on the roller 100 of the first conveying device E is received while being damped by the damper 138 provided on the mold setup frame F, and the positioning claw 108 is moved onto the cylinder 1.
07, the mold A is pushed out and held at a predetermined position on the roller 64.

Furthermore, the mold A transferred from the separating device C to the reversing device D is transferred to the slope 68 of the rod 68 provided at the entrance side of the reversing device D, as shown in FIGS. 7a and 8.
The lower mold master plate 9 is applied to a, and by pushing down the rod 68 against the spring 72, the reversing device D is moved from above the roller 27 of the separating device C.
However, if the trailing edge of the master plate 9 passes over the mountain of the rod 68, the rod 68
8 is immediately raised by the action of the spring 72, and supports the rear edge of the master plate 9 by the stepped portion 68b. Therefore, there is no risk that the mold A will move backward. Also, the front edge of the master plate 9 is the first
It is positioned by the positioning claw 119 of the transport device E.

The mold A positioned on the roller 64 is fixed by the mold holding plate 79, which is lowered by the operation of the cylinder 78 provided on the upper part of the wheel 52, and pouring is performed as described above. The mold casting method of the present invention involves repeating the above-described operations.

As described above, the present invention is formed by dividing the mold casting device into parts according to each function, and by arranging these devices in a circle via a conveying device, it is possible to use a large number of molds to achieve extremely efficient multicasting. It has the excellent effect of being able to cast various types of products.

In other words, conventional mold casting equipment is a one-piece,
Since the process from pouring the molten metal to taking out the product was performed using the same machine, production efficiency was poor due to the long solidification time of the molten metal and the waiting time required to take the product out of the mold. Since each work is performed concurrently using separate molds, the above-mentioned waiting time is no longer necessary.

In addition, with conventional mold casting machines, the applicable molds were determined, so when casting many types of castings,
There was a problem that a number of mold casting machines had to be installed according to the type of mold, which increased the cost accordingly, but according to the present invention, the external shape of the master plate provided above and below the mold It is extremely convenient because different types of products can be cast if the dimensions are kept constant.

Since the present invention is as described above, it has excellent effects contributing to the development of this type of industry.
