Claims

[Scope of utility model registration request]

A recess that communicates with the resin flow path of the parting surface is formed on the parting surface of the fixed mold of a molding die consisting of a fixed mold and a movable mold, and the mold is opened by being compressed by the injection pressure of the resin material in the recess. A protruding member urged by an elastic member that sometimes expands is inserted, and when the material is injected, the resin material flows into the recess, and when the mold is opened, the resin part is pushed out of the recess by the protruding member. A mold for injection molding characterized by being ejected and released from a fixed mold integrally with a molded product.
