With the fixed mold plate 7 closed, the resin flows into the molding section 2 from the submarine gate 3 to perform injection molding. After the injection molding, the movable mold plate 1 is operated to release the mold. However, even when the movable mold plate 1 is moved, although the movable mold plate 1 slides relatively to the movable mold plate 1 due to the bias of the spring 6, the cavity 4 remains stopped. In this state, the submarine gate 3 is exposed as shown in FIG. Further, when the movable mold plate 1 is moved, the flange 4a is attached to the bottom end of the sliding groove 5.
Abuts and also moves the cavity 4. As the cavity 4 moves, the gate is moved between the fixed mold plate and the movable mold plate.
