Copper bush casting mold

Abstract

The invention relates to the technical field of casting molds, in particular to a copper bush casting mold. The copper bush casting mold comprises an upper mold body, a lower mold body and a sand core, wherein the bottom face of the upper mold body is attached to the top face of the lower mold body, and part grooves and sand core grooves are formed in the central positions of the bottom face of the upper mold body and the top face of the lower mold body; and the inner wall outline of the part grooves is half of the outer outline of a part, and the inner wall outline of the sand core grooves ishalf of the outer wall outline of the sand core. According to the copper bush casting mold, through the arrangement of an upper cooling channel and a lower cooling channel, the upper mold body and the lower mold body are cooled at the same time, so that consolidation molding and cooling of the part are accelerated, meanwhile, the cooling process is conveniently controlled, cooling water is conveniently collected, and secondary utilization of the cooling water is facilitated; through the arrangement of a threaded rod, the upper mold body is conveniently moved out; and through the arrangement of an extrusion sliding block and a jacking sliding block, the lower mold body is conveniently separated from the part, so that demolding of the part is facilitated.

Description

technical field [0001] The invention relates to the technical field of casting molds, in particular to a copper sleeve casting mold. Background technique [0002] Casting is the process of smelting metal into a liquid that meets certain requirements and pouring it into a mold, cooling and solidifying, and cleaning to obtain a casting with a predetermined shape, size and performance. Because the casting blank is almost formed, the purpose of free machining or a small amount of processing reduces the cost and reduces the production time to a certain extent. Casting is a relatively economical blank forming method, and it can show its economy for parts with complex shapes. sex.

Problems solved by technology

[0003] Existing copper-sheathed casting molds generally wait for the parts to solidify and cool naturally, or spray cooling water on the surface of the mold, which takes a long time for natural solidification and cooling. Different degrees of shrinkage from top to bottom lead to part deformation, and it is not conducive to the secondary utilization of cooling water, which is not conducive to improving production efficiency. During the part demoulding process, due to the adhesion between the part and the mold, it is difficult to demould the part
