Description

Technical Field

[0002] New energy battery shell demoulding mold refers to the mold used to manufacture new battery shells. It is a special mold with specific design and function to meet the manufacturing needs of new energy battery shells. The mold is usually made of high-strength and wear-resistant materials to ensure the life and stability of the mold.

[0003] As disclosed in a Chinese utility model patent, a demoulding mechanism for a new energy vehicle power battery protective shell mold (publication number: CN217370074U) includes: an upper mold is arranged above the lower mold, a convex mold is arranged on the surface of the lower mold, and a guide ring groove is opened on the surface of the lower mold; a guide column is arranged inside the guide ring groove; and a guide ring sleeve is arranged on the surface of the guide column.

[0004] As the carrier of the battery module, the battery casing plays a key role in the safety protection of the battery module. Most of the existing battery casings are compression molded by extrusion of a concave mold plate and a convex mold plate. After molding, the mold plates are separated to take out the protective shell. In the actual production process, demolding failure often occurs. The battery casing will be buckled on the surface of the convex mold plate. When manually removing the battery casing from one side, the battery casing may be stuck or even damaged due to some special shapes, which makes the operation inconvenient. Summary of the invention
