<p>A mold opening and closing mechanism for an I.S. machine has a plurality of individual sections, each having a pair of opposed mold support mechanisms (16) displaceable between a separated retracted position and an advanced position where molds carried by the mold support mechanisms will forcefully engage. A drive (19) is operatively associated with each mold support mechanism, and includes an electronic motor. A predetermined torque is applied to the motors for a period of time when the opposed pair of mold support mechanisms are at the advanced position. To return the mold support mechanisms to the start position the electronic motors are operated at a slow velocity for a period of time and then operated to rapidly displace the mold support mechanisms to the start position.</p> |
