Abstract
A plunger assembly for a glass forming machine comprises an assembly housing (), at which a drive () is in contact with a drive spindle, which is supported in an axially non-displaceable manner, via an angular gear, which drive spindle, in turn, engages with a spindle nut, the spindle nut housing () of which is set up via an assembly () by interpositioning pressing force limiters for transferring the pressing force required for a forming process to two plungers (). The assembly () can be displaced in a non-rotatable manner along two guide columns (), which are arranged parallel to one another in a housing-fixed manner, and the spindle nut housing () engages with two lateral linear guides, which are also arranged in a housing-fixed manner. The connection between the assembly () and the spindle nut housing () is designed in such a way that only forces in the direction of the pressing force are transferred, so that any other forces and moments originating from the forming process are transferred to the housing, so that in particular the drive spindle is only axially stressed.
