摘要：
A die casting mold includes a resistance member (17) disposed in a vent passage (16) to reduce a flow velocity of molten metal as the molten metal advances along the vent passage. The resistant member comprises a plurality of discrete protrusions (24) arranged in staggered relation to one another in both a longitudinal direction and a transverse direction of the vent passage so as to define therebetween a labyrinthine part (34) extending between an inlet side and an outlet side of the vent passage.
