Abstract

PURPOSE:To prevent development of gap caused by difference in heat expansions by forming projecting part at a closing valve side of one side of a die and arranging a valve chamber communicating with exhaust introducing passage for venting gas in there. CONSTITUTION:The projecting part 5 projected toward a core 1 in a core 2 at a movable die 4 side in the cores 1, 2 fixed by pushing in a part of partition line PL of a fixed die 3 and the movable die 4 is arranged. In the projecting part 5, the valve chamber 8 communicating with the exhaust introducing passage for gas is arranged. Just before pouring molten metal into a cavity 6, valve body 17 in the valve chamber 8 is retreated, so that the molten metal is prevented from insertion into a cylinder seal 15, even if a part of the molten metal filled up in the cavity 6 is invaded into the exhaust introducing passage 7. By this die, even if the difference in heat expansions between the cores 1, 2 caused by sequential casting operations is developed, the gap between the valve chamber 8 and the valve body 17 is not developed, and the invasion of the molten metal is prevented.
