Abstract:
A mold opening and closing mechanism for an individual section of an I.S. machine having a pair of opposed mold support mechanisms displaceable between a separated retracted position whereat each mold support mechanism is located at a start position and an advanced position whereat molds carried by the mold support mechanisms will forcefully engage, comprisingan electronic motor operatively associated with each of the mold support mechanisms to displace the mold support mechanisms between the retracted and advanced positions, andcontroller means for controlling the operation of said electronic motors includingmeans for operating each of said electronic motors to displace its associated mold support mechanism to a center location where it will engage the other mold support mechanism, andmeans for driving at least one of said electronic motors to apply a predetermined torque for a selected period of time when the mold support mechanisms are engaged at the center location.
