置。 A fixed plate that holds a fixed mold, a movable plate that holds a movable mold, a hydraulic cylinder that moves the movable plate back and forth with respect to the fixed plate, and when the movable plate approaches the fixed plate, the movable plate holds the movable mold. After the mold and the movable mold close the mold, the tie bar is fixed to the fixed plate to clamp the mold.The tie bar is fixed to the movable plate or the fixed plate, and the fixed plate and the movable plate are connected. The connection and fixation of the mold is carried out by a mold clamping device using a half nut that opens and closes almost perpendicular to the tie bar located on the opposite side of the mold mounting surface of the movable or fixed platen, and a mold clamping device installed on the movable or fixed platen. In an injection compression molding device that molds a molded product using a clamping cylinder, the stroke amount of the clamping cylinder is 100 to 300 mm, and the mold fitting of the fixed side mold and the movable side mold is performed by a hydraulic cylinder that moves the movable platen back and forth. Once this is done, the pressure oil on the mold-closing side of the hydraulic cylinder is switched to the mold-clamping side of the mold-clamping cylinder, and the mold is opened by a predetermined gap necessary for injection compression molding using a position detector on the movable platen. An injection compression molding apparatus comprising a servo valve that controls pressure oil so that it is compressed by the mold clamping cylinder after the injection operation is performed.
