るゲートピン駆動機構。[Scope of Claim for Utility Model Registration] (1) A gate pipe is connected to the manifold pipe, a gate pin is placed inside this gate pipe, and the gate opening provided at a predetermined position of the mold is opened and closed by this gate pin. By detaching the gate pin from the gate port, the molten resin that has passed through the manifold pipe and the gate pipe is supplied from the gate port into a mold device consisting of an upper mold and a lower mold. A gate pin drive mechanism in a molten resin pressure molding apparatus configured to perform pressure molding, wherein a hydraulic cylinder for vertically moving the gate pin is installed on the lower surface of the tip of the manifold pipe. (2) The gate pin is arranged so as to pass through the center of the hydraulic cylinder in the vertical direction and be driven to move up and down, and the lower end of the hydraulic cylinder is operated by the downward movement of the gate pin and is connected to a molten resin supply drive source. 2. A gate pin drive mechanism in a molten resin pressure molding apparatus according to claim 1, further comprising a limit switch.
