Patent ID: 7017374

Claim:
A device for closing and opening mold halves of at least one mold of a glass forming machine, comprising: a mold half holding mechanism for each of said mold halves; a glass forming machine frame; a drive for effecting the opening and closing of said mold halves; a spindle mounted in an axially fixed manner, said spindle being drivable rotatably in a reciprocal manner by said drive; a nut mounted for linear reciprocal movement in response to rotational movement of said spindle; a drive element having a longitudinal axis, said drive element being mounted for reciprocal linear movement in response to movement of said nut; a guide device disposed to prevent rotational movement of said drive element; a drive shaft mounted for reciprocal pivotal movement in response to movement of said drive element; and each of said mold halves being associated with a vertical shaft connected via a lever mechanism to said drive shaft, said vertical shafts being mounted in said frame for rotational movement in response to movement by said drive shaft, each of said mold half holding mechanisms being pivotal in a reciprocal manner in response to movement of said vertical shaft associated therewith.
