ABSTRACT:
A mold opening and closing mechanism for an I.S. machine including a pair of mold support mechanisms supported for displacement between a retracted position and an advanced position where they will engage. A mold support mechanism is displaced by a transmission including a lead screw which is supported by a housing, left hand and right hand nuts operatively associated with the lead screw, and links interconnecting the left hand and right hand nuts and the mold support mechanism. The housing has a rear wall defining a flat surface, and the left hand and right hand nuts have a flat rear bearing surface, the rear wall flat surface and each of the bearing surfaces has a selected spacing therebetween when the mold support mechanism is at the retracted position, and the lead screw has a rigidity selectively chosen so that when the mold support 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 bearing surfaces and the rear wall flat surface, whereby the mold support mechanism will be positively maintained at the advanced position. A motor coupled to the lead screw drives the transmission.
