ABSTRACT:
Opposed mold supports of a mold opening and closing mechanism are driven by electronic motors between retracted and advanced positions. The motors are electronically geared together and follow a feed program which initially advances the associated mold supports a set distance which is half the separation distance. When the displacement of both supports stops, both motors are operated at a slow velocity. When it is determined again that both supports have stopped, the location of each is verified to be within an acceptable range and each motor is then operated to apply a desired clamping load.
