Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, specifically to an injection mold for a cardiac pacemaker connector. Background Technology

[0002] Injection molds are tools used to produce plastic products, and they also give plastic products a complete structure and precise dimensions. Injection molding is a processing method used in the mass production of parts.
