イキヤスト用ガス抜き装置。 A recess opening facing the mating surfaces of the fixed mold and the movable mold is formed, and a valve body having a valve portion that slides within this recess is provided, and a valve body is provided along the mating surface from the cavity. An inflow groove that communicates with the dynamic pressure working space on the open end side of the recess, a detour groove that extends from the dynamic pressure working space to a detour point remote from the recess, and a communication groove that communicates the detour point with the side surface of the recess. At the same time, an exhaust flow path is formed that communicates the bottom side of the recess with the outside, and further, the valve portion is located closer to the bottom of the recess than the bottom of the communication groove, so that the communication groove and the bottom of the recess are connected to each other. A communication blocking block is provided within the communication groove to block direct communication of the dynamic pressure working space with the communication groove without going through the detour groove until the communication with the side is cut off. A degassing device for die casting characterized by the following.
