Description

Technical Field

[0001] The utility model belongs to the technical field of injection mold equipment, and particularly relates to an injection molding structure in which an insert is placed in a mold. Background Art

[0002] Injection molds are tools used to produce plastic products and give them their complete structure and precise dimensions. The metal insert injection molding process involves pre-fixing the metal insert in the mold before injecting the plastic to form the part. After the mold is opened, the insert is tightly encased by the cooled and solidified plastic to create the part. Existing metal insert injection molding processes often involve inserting copper parts into the product. However, the copper parts' structural design creates an undercut that prevents them from being ejected using conventional mechanisms, hindering their proper function. Summary of the Invention
