Beschreibung
Zusammenfassung:	A pressure receiving pin includes a fitting portion that fits in a through hole provided in a fixed mold and communicating with a portion of an exhaust passage on an inlet side, a distal end portion that is located coaxially with the fitting portion at a position closer to the exhaust passage than the fitting portion, that slides with respect to the through hole upon reception of molten metal, and that has a columnar shape, and an intermediate portion that is located coaxially with the fitting portion and the distal end portion at a position between the fitting portion and the distal end portion and that has a diameter smaller than a diameter of the distal end portion. An air supply device is provided that supplies air at a time of opening a movable mold such that the air passes through a gap formed between an outer peripheral surface of the intermediate portion and an inner peripheral surface of the through hole and a gap formed between the distal end portion and the fixed mold and flows out to the movable mold.
