Description
Technical Field
The utility model relates to an injection mold field especially relates to a disconnected runner structure of injection mold gear.
Background
An injection mold is a tool for producing plastic products; the injection molding is a processing method used for batch production of parts with complex shapes, and particularly relates to a method for injecting heated and molten plastic into a mold cavity from an injection molding machine at high pressure, and obtaining a formed product after cooling and solidification.
When an injection mold is injected by an injection molding machine, after a plastic part is molded, a sprue is usually formed by waste materials, and the plastic part is easy to damage by adopting forced demolding.
SUMMERY OF THE UTILITY MODEL
