ABSTRACT:
Each mold half is held by means of a mold half holding mechanism which can be driven so as to pivot in a reciprocating manner about a common vertical hinge column by means of a vertical shaft (6; 7), which is mounted in a rotatable manner in a frame (2) of the glass forming machine (1), and by means of first intermediate members. Each shaft (6; 7) is connected via a lever mechanism (8; 9) to a common drive shaft which can be pivoted in a reciprocating manner by means of a drive element (19), which can be moved linearly in a reciprocating manner, of a drive (20) and by means of second intermediate members (18). The drive element (19) can be mounted on a nut (26) and secured against rotating about a longitudinal axis (39) of the drive element (19) by means of a guide device (32). The nut (26) is in engagement with a spindle (33). The spindle (33) is mounted in an axially fixed, rotatable manner and can be driven rotationally in a reciprocating manner by means of the drive (20).
