Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and more specifically, to an arc core-pulling mechanism for an injection mold of an automotive charging port cover. Background Technology

[0002] In the injection molding process of automotive charging port covers, due to the structural characteristics of the covers, there are often undercuts or protrusions with arc shapes. For these injection molded parts with arc features, a special core-pulling action is required during mold demolding. Traditional linear core-pulling mechanisms cannot meet the core-pulling requirements of arc shapes. If a forced demolding method is used, it can easily lead to product damage, affecting product quality and yield. Therefore, we designed an arc-shaped core-pulling mechanism for automotive charging port cover injection molds. Utility Model Content
