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.

Abstract: A hydraulic drive unit for a shaping machine comprising a pump driven by a motor, a closed-loop or open-loop control unit for closed-loop and/or open-loop control of the drive unit to a reference operating point of the drive unit, and a memory connected to the closed-loop or open-loop control unit, wherein a relationship between a parameter characteristic of a sound directly or indirectly caused by the drive unit and a data set representing various operating points of the drive unit is stored in the memory and the closed-loop or open-loop control unit is adapted to select the reference operating point on the basis of the relationship.

Abstract: A hydraulic drive device for a molding machine includes at least one motor, such as an electric motor, at least one first hydraulic pump which can be driven by the at least one motor, and at least one flywheel. At least one second hydraulic pump is connected, or can be connected, with the at least one flywheel, and a hydraulic connection conduct is provided between the first hydraulic pump and the second hydraulic pump.
