Problems solved by technology

At this time, since the temperature of the sliding transverse mold is lower than that of the lower mold, the thermal expansion is small, and the sliding transverse mold may not come into contact with the adjacent sliding transverse mold.
In this case, there is a possibility that the sliding transverse mold pushed by the actuator will take an inclined posture of falling toward the center of the mold

Embodiment Construction

[0023] refer to Figure 1 to Figure 3 , a casting mold according to an embodiment of the present invention will be described.

[0024] refer to figure 1 , the casting mold 1 of the present embodiment constitutes a main part of the casting machine 2 . The casting machine 2 casts a cylinder head of an automobile engine by a low pressure casting method.

[0025] The casting machine 2 includes a base 3 on which the mold 1 is arranged. The mold 1 includes a lower mold 4 that is fixed to the base 3 , and first to fourth sliding transverse molds 5 to 8 , which are arranged to surround the base 3 in four directions from the side surface of the lower mold 4 . Lower die 4; and upper die 9 (refer to figure 2 ), which is arranged so as to cover the space from above the space defined by the lower mold 4 and the first to fourth sliding transverse molds 5 to 8 . The first to fourth sliding transverse molds 5 to 8 are slidable from the mold opening position to the mold closing position ...

Abstract

The present invention is a casting mold provided with a lower mold 4 fixed on a base 3, multiple sliding side molds 5-8 that slide freely on the base 3 between a mold-opening position and a mold-closing position, an upper mold 9, and sliding mechanisms 12, 25 for sliding the sliding side molds 5-8 in the sliding directions. When sliding the sliding side molds from the mold-opening position to the mold-closing position, the sliding mechanisms 12, 25 cause forces to act on the lower section of the sliding side molds 5-8 and prevent the action of forces on the upper section of the sliding side molds 5-8.

Description

technical field [0001] The present invention relates to a casting mold including a lower mold fixed to a base and a sliding transverse mold slidably on the base. Background technique [0002] Conventionally, a technique of casting a cylinder head of an automobile engine by a low pressure casting method has been known. As a casting machine of this low pressure casting method, there is known a casting machine having a structure in which a melting furnace is arranged below a mold, the mold is composed of an upper mold and a lower mold having a gate, and a melting furnace stored in the melting furnace is known. The molten metal is pressurized to push up the molten metal, and the molten metal is supplied into the mold through the gate of the lower mold through the runner (feed pipe). [0003] In addition, in this type of casting machine, when casting a product having a complex shape that cannot be cast only with the upper and lower molds, a sliding transverse mold is further use...
