Abstract:
1. Process for producing pressing force of an injection unit of an injection molding machine on a mold, the process including: a) actuating a linear drive unit to bring the injection unit to rest on a mold, a working cylinder unit being supplied with a fluid via a store during the axial displacement of the injection device until the required rest position on the mold is reached, after reaching the rest position on the mold, a blocking element is closed to block passage of the fluid into the store during further actuating and a connection element within a connection unit is opened to release a supporting element of the connection unit thereby allowing for displacement of the fluid during further actuating; and b) further actuating the linear drive unit to displace a displacement piston relative to a hydraulic element to produce an increased pressure in the working cylinder unit via a fluid connection in the hydraulic element to increase the contact pressure of the injection unit on the mold.
