置。 A die casting device that injects molten metal under pressure into a cavity that is formed when a first mold and a second mold that can move toward and away from the first mold are brought together. A gas vent groove is formed in at least one of the first mold and the second mold to communicate the cavity with the outside of the mold, and the groove extends along the flow direction of the gas in the groove. A fixed block provided with a plurality of concave and convex portions is provided on one of the first mold and the second mold, and a movable mold is formed with a concave and convex portion that fits with the concave and convex portions of the fixed block with a predetermined gap therebetween. a block is attached to the other of the first mold and the second mold so as to be movable in a direction perpendicular to the direction of the approaching and separating movement and also perpendicular to the flow direction of the gas; A degassing device for die casting, wherein a positioning pin is provided on one side of the movable block, and a positioning hole into which the pin fits is formed on the other side.
