Description

Technical Field

[0001] The invention mainly relates to the technical field of metal casting, and in particular to an automatic casting cooling and demoulding device. Background Art

[0002] Metal casting is a widely used process for manufacturing various parts and components. It uses the plasticity of molten metal to precisely inject it into a preset mold to shape parts with specific shapes and precise dimensions. During the casting process, a casting cavity is first constructed, and then the molten casting liquid is slowly injected into it. After it cools and solidifies, the mold is opened and the delicate component cast by metal is taken out.

[0003] Currently, the casting process generally relies on manual operations, including manual cooling, mold closing, mold separation, demoulding, transportation and handling, etc. However, due to the extremely high temperature of the casting, these manual operations are not only inefficient, but also pose great safety hazards, and dangerous accidents are very likely to occur during demoulding and handling.
