Claims

[Scope of utility model registration request]

The core pin 14 of the mold, which forms the hole of an injection molded product made of synthetic resin or the like with an undercut on the outer diameter, is pulled out of the molded product before it is projected from the template, and the molded product is removed from the template. This injection mold is characterized by being configured so that when ejecting, elastic deformation occurs inward and the undercut portion is ejected without being deformed.
