Description

Shell casting box

Technical Field

The utility model relates to the technical field of casting, in particular to a shell casting box.

Background

Casting is a metal hot working process in which liquid metal is cast into a casting cavity conforming to the shape of a part, and after it has cooled to solidify, the part or blank is obtained. Shell casting is a casting method in which a mold is formed by a mold. Specifically, the wax pattern or the mud pattern is manufactured into a shell through a plurality of processes, casting alloy is injected into the shell, the shell and the casting are taken out after cooling, and finally the rest of the shell is removed. This method can produce castings having complex shapes and good surface quality. The existing casting box is usually provided with a fixing device by directly placing the core into the box body, when the box cover is covered, the core is easily pushed away from the original position, the thickness of the cast shell is uneven, the quality of the cast shell is not up to standard, and the cast shell is easy to discard, so that the shell casting box is provided.
