Claims

[Scope of utility model registration request]

An extrusion block having a molded part of the undercut part is provided in one mold so as to be slidable in a direction inclined with respect to the direction of the other mold, and the extrusion block has a molded part of the undercut part in a different direction and the mold. A slide block having a contact surface facing outward and inclined with respect to the direction of the other mold is provided so as to be slidable toward the outside of the mold, and the other mold has an inclined surface on which the contact surface of the slide block slides. In the injection molding die, the extrusion block and the slide block are slid in respective directions to separate the molded parts from the respective undercut parts when the molded product is released. An injection molding mold characterized in that the opposing portions of the other mold are provided with an engaging portion and a guide portion that engage with each other and guide the slide block in the direction of inclination of the abutment surface.
