ABSTRACT:
The present invention is directed to an apparatus for pressing a glass article. The apparatus includes a frame. A mold having first and second mold halves are mounted on the frame. The mold halves define a cavity for receiving a glass gob. The mold halves are movable between open and closed positions. The apparatus includes a device for opening and closing the mold halves. A plunger is movably mounted on the frame adjacent the cavity. The plunger presses the glass gob into the cavity to form the glass article. The apparatus further includes a device for moving the plunger. An alternative embodiment of the invention is directed to a machine for pressing a plurality of glass articles at a high cavity rate. In this embodiment, the machine includes at least two apparatus as described above mounted on a device for moving the apparatus. The method of the present invention for using apparatus for pressing a plurality of glass articles at a high cavity rate includes the steps of: (a) rotating a carriage to which at least two apparatus as described above are attached; (b) actuating the device for opening and closing the mold to close the mold; (c) placing the glass gob adjacent the cavity; (d) actuating the device for moving the plunger to move the plunger to press the glass gob into the cavity to form the glass article; (e) withdrawing the plunger; (f) actuating the device for opening and closing the mold to open the mold a predetermined distance to cool the mold; and (g) actuating the device for opening and closing the mold to open the mold to remove the glass article from the cavity.
