Abstract
The invention relates to a mold closing device without cross-beam for an injection molding machine having a C-shaped machine frame, a fixed tool mounting plate supported therein and an end plate, as well as a movable tool mounting plate longitudinally movable on antifriction guideways and guide bars. It is the object of the invention to provide an inexpensive and simple adjustment which assures the concentricity between the fixed tool mounting plate and the end plate during deformation of the machine frame as a result of the closing force and which eliminates the machining tolerances among the hinge points on the guide bars. The solution provides that the guide bars are horizontally frictionally attached to the machine frame, are vertically biasable via springs against the fixed tool mounting plate and against the end plate, and are supportable via springs between the end plate and the fixed tool mounting plate.
