[0002] Cold extrusion is an important part of precision plastic bulk forming technology. Cold extrusion dies are dies that place metal blanks in a cold state. Under strong pressure and a certain speed in the cavity, the metal is forced to extrude from the cavity, thereby obtaining an extruded part with the desired shape, size and certain mechanical properties. Obviously, cold extrusion processing relies on the die to control the flow of metal and the large transfer of metal volume to form parts.

[0004] However, after the actual use of extrusion molding, the molded workpiece is not easy to remove quickly, and the mold lacks a rapid discharge and pushing mechanism for the molded part. There are certain limitations in its use. In addition, debris will remain inside the mold during extrusion molding, and the retention of debris will affect subsequent extrusion operations.
