DIE CASTING MACHINE ABSTRACT OF THE DISCLOSURE Die casting apparatus for casting parts such as rotors or the like comprises a three tie bar horizontally dis- posed die casting machine, with an indexing mechanism mounted on one of the tie bars for rotating the parts through six separate radially spaced work stations. The work stations include loading, casting, cooling, skew pin ejection, and unloading stations. The casting station includes a four plate die assembly comprising a runner plate, cover die,carrier plate, and ejector die. The die assembly employs pin-point gating and is formed such that the cast part is removed from the die and the runner system,and the runner system is ejected from the apparatus,while the part is at the casting station. A movable runner ejector plate having ejector pins ejects the runner from the runner plate. A compensating cylinder is provided for adjustment for variance in stack height. An ejector mechanism employing ejector pins removes the cast part from the ejector die so as to permit the cast part to be rotated to the next work station. Toggle linkages open and close the die assembly, with the toggle linkages being inclined inwardly at an angle of 10° with respect to the tie bars between the back plate and the traveling plate.
