APPARATUS FOR DIE CASTING AN INTERNAL PASSAGEWAY AND A PRODUCT MANUFACTURED THEREWITH

摘要

A die casting apparatus (30) comprises a pair of mold assemblies (32, 34) which include molding surfaces cooperating to define a first mold cavity (35) therebetween for casting a first portion of a cast object in the first mold cavity. One of the mold assemblies comprises a fixed mold core (36, 38), and a movable mold core (40) movable with respect to the fixed mold core along a core axis between a closed position and an open position. The mold cores include casting surfaces (36a, 38a) disposed such that in the closed position the casting surfaces cooperate to define a second mold cavity therebetween extending transversely to the core axis and in communication with the first mold cavity for casting a remaining portion of the object integral with the first portion, while in the released position the object is substantially released from the one mold assembly.
