ABSTRACT:
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.
