Operating mechanism for a glassware forming machine

A mold operating mechanism to open and close molds of a glassware forming machine. The mechanism includes a drivetrain assembly including a frame, a gearset carried by the frame and configured to be driven by a powertrain assembly, at least one operating shaft carried by the frame and driven by the gearset, and at least one linkage operatively coupled to the operating shaft and configured to be operatively coupled to a mold carrier carrying at least a portion of one or more molds. The mechanism includes further a fluid cylinder disposed proximate the linkage and including at least one piston rod operatively coupled to the linkage, wherein as the linkage rotates, the piston rod is pulled outward from the cylinder, and the cylinder is dragged outwardly, and whereafter the cylinder is pressurized with fluid to push the piston rod further outward to apply clamping pressure to the linkage.
