摘要： A system and process for producing pressing force of an injection unit of an injection molding machine on a mold, which comprises the steps: a) actuating a linear drive unit to bring an injection device to rest on a mold; a working cylinder unit being supplied with fluid via a store during the axial displacement of the injection device until the required rest position on the mold is reached. Provision is made according to one aspect of the invention in that after reaching the rest position on the mold, a blocking element is closed and the connection within a connection unit is opened, and b) the linear drive unit is further actuated, c) a displacement piston is displaced relative to the hydraulic element, and d) increased pressure is produced 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.

摘要： Injection unit for an injection molding machine to process material, comprising a plasticizing cylinder, a screw, and a screw drive including two electric motors, such that the two motors have an electrically controlled connection to one another, to implement an injection and metering process, such that the two motors can be operated in the same or opposite direction of rotation and with the same or different rotational speed. A space is formed by at least two sleeves which can move relative to one another, and by respectively adjoining plate members, so as to take up lubricating oil, such that the sleeves can slide into one another, and the junctions of the parts which form the space are constructed tight against the environment, at least for lubricants.
