スタンピング成形装置。[Claims for Utility Model Registration] Stamping on a thermoplastic resin sheet comprising a male mold and a female mold, by pressing a preheated and softened thermoplastic resin sheet with the male mold and the female mold. The stamping molding device is of a type that forms a through hole at the same time as performing molding, and the stamping molding device is provided with a molding surface of the male mold and a molding surface of the female mold protruding in the pressing direction of the male mold and the female mold, a protrusion having a protrusion height larger than the thickness dimension of the thermoplastic resin sheet after stamping molding; a bottomed fitting hole filled with a plastic resin sheet and into which the protrusion is fitted by a predetermined amount; a hole provided at the bottom of the fitting hole; and a hole movable toward and away from the protrusion. a movable member that is fitted into the hole and prevented from moving beyond a certain limit in the direction approaching the protrusion; and the movable member is constantly biased in the direction approaching the protrusion during stamping forming. Until the protrusion starts fitting into the fitting hole, it is not elastically compressed and deformed via the movable member due to the pressure of the thermoplastic resin sheet filled in the fitting hole. a spring that is elastically compressed and deformed via the movable member as the pressure of the thermoplastic resin sheet filled in the fitting hole increases after the protrusion starts fitting into the fitting hole; A stamping molding device for a thermoplastic resin sheet, comprising:
