ABSTRACT:
A mounting arrangement for a die closing unit on the machine base of an injection molding machine, where the machine base has two guide rails with parallel horizontal and vertical guide faces welded to the upper edges of its U-shaped base member, the stationary die carrier plate and the stationary cylinder head plate of the die closing unit being positioned and positively centered by the guide faces of the guide rails, and the movable die carrier frame being adjustably guided on the same guide faces. The cylinder head plate is free to execute small displacements along the guide rails, in compensation for the periodic elongation of the tie rods, when the closing pressure is applied to the injection molding die.
