Abstract (en)
[origin: EP0274183A2] A die casting apparatus (10) for forming rotors for electric motors includes a frame (12) having two opposed stationary pressure plates (16,18) and a rotating turret (22) rotatably mounted between these stationary plates for movement between three stations. The turret includes three apertures at three equally spaced locations around the turret. Tooling is arranged at each of the three stations for forming a rotor. Compensating and casting tooling (42, 30, 36) is located at a first station, pin pressing and trimming tooling is located at the second station and unloading tooling (52, 54) 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.
