Description

A demoulding device for casting

technical field

The utility model relates to the technical field of demoulding production, in particular to a demoulding device for casting.

Background technique

Casting is a method in which liquid metal is poured into a casting cavity adapted to the shape of the part, and after it is cooled and solidified, the part or blank is obtained. The material to be cast is mostly a metal that was originally solid but heated to a liquid state (for example: copper, iron, aluminum, tin, lead, etc.), and the material of the mold can be sand, metal or even ceramics. Depending on the requirements, the methods used will vary.

During casting, two molds are used to close the mold to form the casting. After the mold is formed, a demoulding device is needed to separate the two molds. Existing demoulding devices usually use one mold as a fixed mold and the other mold as a movable mold to complete mold closing and demoulding. This method is slow in demoulding speed, and the efficiency needs to be improved.

Utility model content

The utility model provides a demoulding device for casting, which has the beneficial effect of completing the demoulding and clamping through the simultaneous reverse movement of two molds, greatly improving the demoulding efficiency, and solving the problems mentioned in the above-mentioned background technology.
