Claims

[Claims for Utility Model Registration] A pair of center core portions 8 and 9 having abutment surfaces 8a and 9a that abut each other to form the inner shape of the cylindrical rubber molded product 1, and each center core portion 8, One of the pair of mold members 6 and 7 consisting of a pair of mold support parts 10 and 11 that support the mold member 9 and are in contact with each other is used as the movable mold member 6, and the rubber is placed on both the central core parts 8 and 9. In a state where the molded product 1 is covered, while separating the mold support part 10 of the movable mold member 6 from the other mold support part 11, the center part 8 of the movable mold member 6 is moved toward the mold support part 10 side. By rotating the entire movable mold member 6 so as to move it, both mold support parts 10,
11, in a molding die in which the center core 8 of the movable mold member 6 can be extracted from the die cut slit 4 of the rubber molded product 1 formed at a position corresponding to the base end portion, both the center cores 8, 9. When the abutment surfaces 8a, 9a are viewed from the dorsal side of the central core portions 8, 9 and from above the extension line L of the abutment surfaces 8a, 9a, the dorsal edges 15 of the abutment surfaces 8a, 9a are A molding die characterized in that it is formed on the same plane P as the width direction of the punching slit 4 of the rubber molded product 1 so as to diagonally intersect with the length direction of the slit 4.
