成形用金型の樹脂ゲート構造。[Claims for Utility Model Registration] (1) A resin gate structure provided in a mold for synthetic resin molding, which gate structure is connected from a molten resin supply section and has an end on the inner surface of the mold. It consists of a gate pipe that serves as a facing gate hole, and a gate pin that can freely reciprocate in the longitudinal direction within this gate pipe and opens and closes the gate hole. A resin gate structure for a synthetic resin molding mold, characterized in that an introduction path is formed. (2) A resin gate structure provided in a mold for synthetic resin molding, the gate structure comprising a gate pipe connected from a molten resin supply section and having a gate hole whose upper end faces the inner surface of the mold. The gate pin is reciprocally movable in the longitudinal direction within the gate pipe and opens and closes the gate hole, and a hole for an introduction path continuous from the supply section is opened at a predetermined location on the inner surface of the gate pipe. Features a resin gate structure for synthetic resin molding molds. (3) The resin gate structure of a synthetic resin molding die according to (2), wherein the hole is opened and closed as the gate hole is opened and closed by the gate pin.
