A die casting machine has obliquely slidable die core pieces in an ejector holder block. The ejector holder block may be drawn away from the stationary die half into abutment with an ejection box by linear actuators; complementary male and female surfaces on the ejector holder block and ejection box precisely locate the ejector holder block with respect to the ejection box when the two are in abutment. The ejection box and mated ejector holder block may then be moved into abutment with the stationary die half to complete a die cavity.

[ What is claimed is:] [1.] A mold for a die casting machine comprising:a stationary die half;an ejector holder block mounted for movement forwardly toward and rearwardly away from said stationary die half such that said ejector holder block may be moved forwardly to a closed position forming, with said stationary die half, a die cavity;at least one die core piece slidably mounted in the ejector holder block for movement in a direction making an acute angle to the direction of movement of the ejector holder block between an extended position and a retracted position such that when said ejector holder block is in said closed position and said at least one die core piece is in said extended position, said die cavity is further defined;a moveable ejection box mounted rearwardly of said ejector holder block for movement forwardly toward and rearwardly away from said stationary die half;a rearward face of said ejector holder block and a forward face of said ejection box having complementary male and female locating surfaces for precisely locating said ejector holder block with respect to said ejection box when said ejector holder block is in abutment with said ejection box;an actuator for moving said ejector holder block rearwardly into abutment with said ejection box prior to movement of said ejection box forwardly toward said stationary die half.
