Abstract: An injection unit for a shaping machine includes an injection piston arranged displaceably in an injection cylinder and at least two drive units for displacement of the injection piston. Each of the at least two drive units is lubricated by an oil chamber which is oil-tightly sealed off in relation to the surroundings, and each oil chamber holds an oil volume, above which is arranged an air volume. The air volumes of the oil chambers are connected together in air-conducting relationship by a connecting conduit.

Abstract: A power supply device for a molding machine with an intermediate circuit, which can be connected with at least one drive of the molding machine and is suitable for supplying the at least one drive with electrical energy; a supply module connected to the intermediate circuit; an energy storage device connected to the intermediate circuit; and a closed loop control device for closed loop controlling an energy content of the energy storage device. The energy storage device can be closed loop controlled by means of the closed loop control device so that the energy content of the energy storage device does not go outside a range, in which a power input and/or a power output of the energy storage device is essentially constant.

Abstract: An operating unit has an operating program and a touch-sensitive display screen on which display fields and/or navigation fields can be represented. Upon actuation of the operating fields, operating signals can be sent by a control or regulating device to injection molding machine elements. Upon actuation of the navigation fields, pages of the operating program can be called up. At least one operating group contains the operating fields but no navigation fields, and/or navigation groups contain the navigation fields but no operating fields. At least one passive field in the form of rows and/or columns contains neither operating fields nor navigational fields. The least one operating group and/or the navigation groups is arranged in rows and/or columns, and the at least one passive field is arranged between the navigation groups and/or the at least one operating group.

Abstract: An operating unit includes a touch-sensitive display screen for displaying an operating program, a control or regulating unit for communicating operating signals to injection molding machine elements, and the operating program is stored in the control or regulating unit, and at least one operating button, upon the actuation of which the control or regulating unit triggers an action of an injection molding machine element. The operating program has a hierarchical system architecture with at least one upper installation-specific level and an upper task-specific level. A selection can be made between different installation regions in the installation-specific central level, between different task regions in the task-specific central level, and a plurality of sublevels. Process-relevant program pages associated only with the selected installation region or only with the selected task region can be displayed in each selected sublevel.
