ABSTRACT:
A mold opening and closing mechanism for an I.S. machine which has a pair of mold support mechanisms supported for horizontal displacement between a retracted position and an advanced position. These support mechanisms are linearly displaced by a drive assembly which includes a lead screw, a housing secured to the section frame for supporting the lead screw, a motor coupled to the lead screw, nuts operatively associated with the lead screw, and links interconnecting the nuts with their associated mold support mechanism. The housing has a rear wall defining a flat surface, and the nuts have flat rear bearing surfaces with a selected spacing therebetween when the mold support mechanism is fully retracted. The lead screw has a rigidity selectively chosen so that when the mold mechanism is displaced to the advanced position into engagement with the other mold support mechanism, with a predetermined force, the lead screw will deflect to establish engagement between the flat bearing surfaces and the rear flat wall surface of the housing which is secured to the frame, whereby the mold support mechanism will be part of a continuous solid structure extending from the section frame, up the housing of each of the drive assemblies, across the nuts and the links of each drive assemblies, and across mold support mechanisms thereby positively preventing the vertical or horizontal displacement of the engaged mold support mechanisms from forces applied thereto.
