Description

Technical Field

[0001] The utility model relates to the technical field of die casting moulds, in particular to an anti-sticking die casting mould for a shell. Background Art

[0002] Die casting mold is a mold used for pressure casting. Pressure casting is a metal forming process that obtains metal parts with specific shapes and sizes by quickly injecting molten or semi-molten metal into a precision-made mold cavity under high pressure and solidifying it under high pressure.

[0003] The existing die-casting mold device is not convenient for pressing the upper and lower mold seats, which easily leads to poor quality of die-casting of metal parts, resulting in errors in the size of metal parts, causing certain economic losses, and is not convenient for buffering and shock absorbing the lower mold seat, reducing the practicality of the device; therefore, we propose an anti-sticking die-casting mold for the shell to solve this problem.
