られたことを特徴とする射出成形金型構造。 In an injection molding die for injection molding a molded product consisting of a substantially plate-shaped main body and a protrusion protruding from the lower surface of the main body and having an undercut discontinuous with the main body. In order to release the molded product from the mold after completion of injection molding, a protrusion molding part for forming an upper protrusion is provided on the side of the base core, which is disposed on the lower side of the main body of the molded product. While forming, a guide pin connecting the base core and an ejector member for moving the base core in the mold release direction is fixed in a state perpendicular to the ejector member, and a gap between the base core and the guide pin is fixed. An injection mold structure characterized in that the injection mold structure is provided with a moving means for moving the base core in a direction in which the protrusion molding portion of the base core is separated from the protrusion of the molded product when the molded product is released from the mold.
