A B S T R A C T A compact die closing unit for injection molding machines with four pull-type hydraulic linear actuators and an oversize multi-plate injection molding die whose station- ary die plates engage the piston rods with centering bores, thereby extending the piston rod support to the die separa- tion plane, and whose movable die plates similarly engage the piston rods with centering bores, so as to be carried by the piston rods directly, without the need for a movable die car- rier plate and a stationary cantilever frame supporting the latter. The hydraulic supply lines for the power piston by- pass control valve are arranged in the auxiliary cylinders.
