Abstract

PURPOSE:To cut simply and easily a sprue by taking products which are cast in plural cavities out of a metallic mold prior to thorough solidification and cutting the sprue connecting the products by a hammer member. CONSTITUTION:A conveying member 6 provided with clamping members 5 for respective products along side a metallic mold 4 for casting and a hammer member 13 for the sprue alongside the same are provided. The casting 1 of products 2, 2 connected to each other by, for example, a sprue 3 is cast by the mold 4. The member 6 prepared by being swiveled to the position A is moved downward prior to thorough solidification of the casting 1 and at the same time the members 5 are actuated to clamp the products 2, then the member 6 is moved upward and is swiveled to the position B. If a machine frame 11 in front of said member is advanced and the member 13 is driven, the member 13 hammers the sprue 3 and cuts the sprue.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sprue cutting device used to subsequently divide a product to be cast into two-cavity or other multi-cavity moldings into single pieces.

Hitherto, aluminum alloy pistons and other products, as well as two-cavity and other multi-cavity casting types, are known.
The pieces are connected to each other via an intermediate sprue, and are then cut at the sprue 119i L.
It requires dividing into each product.

Does the present invention involve such work? : The purpose is to obtain a device that is simple and easy to perform, and each product is placed on the side of a mold for casting a casting product consisting of at least two products connected to each other through a sprue. A conveyance member having respective clamp members corresponding to the sprue and a hammer portion side corresponding to the sprue portion are provided on the side thereof, and the cast product is removed from the mold by the conveyor member prior to its complete solidification. When the sprue is taken out and guided to the side, the hammer member is applied to the sprue to completely cut off the sprue.

An attached drawing showing an example of implementing the present invention! I will visit and explain.

In the drawing, (1) is a 2-cavity casting product and other multi-cavity casting products, and the casting product (1) is, for example, a 2-cavity (M-cavity type), and as shown in the diagram, the two products F2J and t2J are the intermediate sprues. Department (
3) are connected to each other via.

In the drawing, (4) indicates a mold for casting the cast product tlJ.
On the side, each product (2), each clamp member (5) that completely clamps each product, and a transport member (5) consisting of a rotating arm at the tip.
6) is prepared so as to be rotatable and vertically movable with a shaft (7) at the base, and the rotation of the shaft (7) causes the first device A to face above the mold (4) and the outside thereof. The second device B can be freely switched between the second device B and the sixth device C in the middle.

As a means for fully rotating the shaft (7), for example, a hydraulic cylinder (9) is provided on its side via a rack and pinion mechanism (8), and furthermore, the shaft (7) can be moved vertically. As means for this, a fluid pressure cylinder α0) extending vertically is provided below the cylinder.

In front of the second position tB and facing it, a machine frame (IIJ) is provided so as to be movable back and forth by a hydraulic cylinder (12I), and a hammer member (
The shaft I31 (141 is installed as a shaft and can be freely driven by a motor or other drive source at the end thereof. In the drawing, 00 indicates the conveyance path below the third position 0 described above.

To explain its operation, the cast product (1) is taken out from the mold (4) prior to complete solidification, guided to the side, and is acted upon by the hammer member (13) prior to solidification. To explain this in detail, the conveying member (6) is prepared in advance by being rotated by the first device A, and then the member (6) is fully moved down and each clamp member (5) is fully moved. Activate it,
Clamp each product (2) completely, and then clamp the corresponding part side (6).
It is moved completely upward and rotated to the second device B. Next, move forward the machine frame 0υ in front of it to bring the hammer member 03) close to the sprue (13), and then move the shaft of the member 031 (1
When driven by the drive source (15) via 41', the member (
I3) strikes the sprue (3) and cuts it. The working area of the hammer member α3) is, for example, indicated by hatching in FIG. 5, and the cutting location E thereof is, for example, indicated by hatching in FIG. 6. The cut pieces of the insect repellent are processed by a chute on the lower side (not shown), and then the conveying member (6) is rotated to the b6 position and is cut downward with the swing A, and in this state, each clamp Member (51'; r: When the operation is released, each product (2) is separated from the other and moves along the conveyance path (le
W1 is placed on top, thus preparing for the next processing. That is, each product (2) is then cut by a cutter at the remaining portion of the sprue (3) to complete the processing.

The member (6) is then moved upward to prepare for the next operation.

The hammer member (131) described above is of the type that is driven by the drive source a!19 to rotate and strike, but the hammer member 03 is of a fixed type, and the conveying member (6) is of the type described above. ) is used to collide the sprue part (3), or the fluid pressure cylinder (I2 is moved forward to collide with the sprue part (3) in front of it) via the hammer member (131 is the former part of the machine frame). Part (3) It is optional, such as making the ball hit all the way.

As described above, according to the present invention, a cast product consisting of a plurality of products prepared in two molds or in a large number of molds is taken out from the mold prior to its complete solidification, and its sprue is inserted into the hammer member. It is possible to separate each product into one piece with high efficiency, and the device as a whole has a conveying member and one side of the mold. and a hammer member, and has the advantage of being relatively simple and compact.
