ABSTRACT:
A mechanism for operating the molds of a glass molding machine. The glass molding machine includes a base and a table rotatably mounted on the base. The glass forming molds are operatively mounted on the rotary table. A plurality of work stations are provided on the base and cooperate to define glass molding cycle for each of the molds. The table is indexed by a drive through a preselected angle by a drive mechanism so that the molds are each moved to each of the work stations. An over the center linkage is provided for normally holding the molds in a closed position. An operating cylinder is at one of the work stations for selectively opening each mold for removal of the formed glass product during the cycle. The indexing drive moves each of the molds past the opening means at least one time during each cycle, each cycle generally being 720.degree., without opening the mold. The linkage also holds each of the molds in the open position for a selected interval for removal of the formed glass product. A cam is provided at another of the work stations for closing each of the molds, with the linkage holding each of the molds in the closed position for a selected time interval during the molding cycle.
