ABSTRACT:
A glassware mold bottom plate mounting arrangement in a glassware forming machine includes a floating ring captured by a cap plate on a base for limited lateral movement with respect to the base and the cap plate. A hollow spud is rigidly secured to and extends from the ring. A cooling wind passage in the base opens through the hollow spud, and a vacuum passage in the base opens through the ring at a position spaced from the spud. A glassware mold bottom plate is removably telescopically received over the ring and the spud. The bottom plate has a central air passage received over the spud, an annular recess received over the ring, and a peripheral air passage that opens into the annular recess such that the central and peripheral air passages open to the cooling wind and vacuum passages in the base through the spud and the ring respectively. The spud and the ring preferably have external seals in respective sliding sealing engagement with the central air passage and the annular recess in the bottom plate. There preferably are face seals between the base and the floating ring, and between the ring and an undersurface of the cap plate.
