ABSTRACT:
A die casting apparatus for forming rotors for electric motors. The apparatus includes a frame having at least two opposed stationary pressure plates and a rotating turret rotatively mounted betewen these stationary plates. The turret includes three apertures at three equally spaced locations around the turret. Tooling is arranged at each of the respective locations for forming a rotor. Compensating and casting tooling is located at a first station, pin pressing and trimming tooling is located at the second station and unloading and loading tooling is located at the third station. The operations at the respective stations proceed simultaneously. The operations are selected so that the combined operations of each of the stations will take approximately equal amounts of time.
