Claims

[Scope of Claim for Utility Model Registration] A cylindrical insert 4 is arranged in a cavity C for molding a resin molded product 1, and the cavity C is
The insert 4 is inserted during molding of the resin molded product 1.
insert 4 into the resin molded product 1.
In a molding die provided with a set pin 8 that is supported in an inclined position so as to intersect with the mold release direction A of the resin molded product 1 and can be detached from the insert 4 when the resin molded product 1 is released from the mold, the mold is inserted into the insert 4. The insertion portion 10 of the set pin 8 extends in the mold release direction A of the resin molded product 1, and the insertion portion 10 is formed to have a smaller diameter than the inner diameter D of the insert 4. A molding die characterized in that urging means 13, 15, and 17 are provided for holding the insert 4 in an inclined state by urging the end portion of the inner circumferential surface of the insert 4 when the insert 4 is inserted.
