Claims

[Scope of Claim for Utility Model Registration] (1) A fixed mold, a movable mold, and a space between the fixed mold and the movable mold that slides on the outer periphery of the fixed mold or the movable mold in the mold clamping direction of the movable mold by means of a telescoping device. It consists of a sliding mold to be installed and a slide core that slides on the side opposite to the side where the expansion and contraction device of this sliding mold is installed and is inserted into the undercut part of the molded product. A compression molding mold having a shape that is inserted into a cavity constituting an undercut portion of a molded product by a moving mechanism when the mold is clamped, and retreated outward from the undercut portion of the molded product when the mold is separated. (2) Utility model registration claim 1, characterized in that the moving mechanism consists of an inclined hole provided in the slide core and an inclined pin provided in the movable mold, and the inclined pin engages in the inclined hole. The compression molding mold described.
