In a two plate closing unit of an injection molding machine the stationary and the movable mold mounting plates are connected by columns, wherein the columns that traverse the fixed mold mounting plate are fixedly connected to a clamping cylinder in which the columns configured at their ends as pressure plungers configured for generating a clamping pressure reciprocate, and while some of the clamping plungers are dual action plungers, the clamping plungers are coupled to a spindle drive and drive unit, such that the spindle drive is at the same time the control drive for a stepped plunger and the closing force and the closing and opening motion is realized by a single drive which operates the spindle and the plunger cylinder unit.
