ABSTRACT:
An injection molding machine for processing plastifiable materials includes a positioning element, a stationary mold carrier fixedly connected therewith, a movable mold carrier defining a mold tentering space with the stationary mold carrier, a closing device for shifting the movable mold carrier in a closing direction into a closed position with the stationary mold carrier, a supporting element for the closing device movably carried by the positioning element, and a clamping unit jointed to the stationary mold carrier and the supporting element at coupling points and adapted to essentially take up occurring forces and deformations and to deviate them around said mold tentering space. The clamping unit is formed of several pieces jointed to the stationary mold carrier or the supporting element at the coupling points and are coupled with each other at at least one first connecting point spaced from the coupling points.
