Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold connection structure. Background Art

[0002] Moulds are indispensable tools in industrial production. They are used to manufacture products of precise shapes and sizes through various molding processes. In industrial production, moulds are used for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain various moulds and tools for the required products. The most common ones are injection moulds and stamping moulds.

[0003] The mold is generally composed of an upper mold, a lower mold and a positioning structure. The upper mold and the lower mold include an upper mold frame, a lower mold frame, an upper mold core and a lower mold core.
