Description

A rotary stripping injection mold

Technical Field

The utility model relates to the technical field of injection molds, in particular to a rotary stripping injection mold.

Background Art

Injection molds are tools in the plastic processing industry that can give plastic products complete configurations and precise dimensions. Injection molds usually include a movable mold and a fixed mold. The movable mold and the fixed mold form a cavity after the molds are closed. Molten plastic is injected into the cavity through the gate and fills the cavity with plastic. Under the cooling effect of the cooling water channel in the mold, the molten plastic is solidified into the shape of the cavity, and then the mold is opened to take out the mold.
