ABSTRACT:
Machine for making pressed glass parts, and particularly cups and stems. A rotatable machine table (4) has several work stations (1) which have one bottom plate (31) each with a means (37) for centering an exchangeably mountable glass mold (3). Each work station (1) has a lift drive for a rod (25) coacting with the glass mold (3). The lift drive contains a first vertical guidance element (8) mounted in the machine table (4). The rod (25) has a second vertical guidance element (20) mounted in the bottom plate (31). Finally, a means for setting the vertical distance between rod (25) and lift drive is provided. To achieve the object of reducing the overall height and weight of the machine, the first vertical guidance element (8) is over its entire length mounted underneath an upper boundary surface (5) of the machine table (4) inside the latter, and the bottom plate (31) is mounted directly on the machine table (4). By designing the machine in accordance with the invention the hitherto used mold table is dispensed with.
