Abstract
Die casting mould has gas vent defined by mutually crossing inclined grooves to prevent eruption of molten material. A die cavity is defined between the projecting portion (3) of a movable die (1) and a corresponding recessed portion in a fixed die. The movable die vertical wall above the die cavity defines parallel semicircular grooves (5) inclined at 5-85 deg. to the vertical and the surface of the fixed die opposite this portion defines similar grooves (6) that are also at 5-85 deg. to the vertical but are inclined so that they cross the grooves in the movable die. Some of the grooves in the movable die communicate with an upper, horizontal vent hole and some with a vacuum source. Molten material is stopped at the intersections of the grooves in the two dies.
