Abstract: An arrangement with a first clamping unit including a first fixed platen and a first movable platen movable relative thereto, a first clamping force mechanism to apply a clamping force to the first movable platen, and a control or regulating unit for controlling or regulating the first clamping force mechanism. Arranged next to and/or above the first clamping unit is a second clamping unit including a second fixed platen or the first fixed platen and a second movable platen movable relative thereto and which are suitable for carrying at least one mold, and a second clamping force mechanism to apply a clamping force to the second movable platen. The control or regulating unit can actuate the first clamping force mechanism and the second clamping force mechanism to apply a clamping force synchronously when all platens present jointly carry a mold.

Abstract: Method for improving a cycle time of a molding system operating in cycles, wherein the molding system is set up to produce molded parts in cycles, wherein the cycles include partial phases, for at least one partial phase or at least one group of partial phases a partial phase duration is measured or ascertained with reference to settings of the molding system, an optimum partial phase duration is calculated for the at least one partial phase or the at least one group of partial phases on the basis of a machine configuration, if the measured or ascertained partial phase duration deviates from the optimum partial phase duration by more than a predefined amount, an indication that the setting of the molding system is improvable with respect to the at least one partial phase or the at least one group of partial phases is issued.

Abstract: A hydraulic drive apparatus includes a first hydraulic pump, a drive motor connected to the first hydraulic pump, a hydraulic line system connecting the first hydraulic pump to the consumer, and a closed-loop control unit. The closed-loop control unit has a first switching element to change a displacement volume of the first hydraulic pump between a predetermined minimum value and a maximum value. A second hydraulic pump is connected to the drive motor, and the hydraulic line system connects the second hydraulic pump to a consumer and has a first branch line connected to the first hydraulic pump, a second branch line connected to a second hydraulic pump, and a main line. The two branch lines open into the main line, and the closed-loop control unit has a second switching element for changing a displacement volume of the second hydraulic pump between a predetermined minimum value and a maximum value.

Abstract: A closing unit for a shaping machine includes mutually moveable mold mounting plates suitable for carrying mold tool portions, a first hydraulic cylinder adapted to apply a closing force to the mold mounting plates, a second hydraulic cylinder, and a pressure storage device connected to the first hydraulic cylinder and adapted to store a pressure prevailing in the first hydraulic cylinder upon pressure relief at a storage device pressure. A hydraulic interconnection of the pressure storage device with the second hydraulic cylinder allows the storage pressure stored in the pressure storage device to be used for locking and/or unlocking the locking device.

Abstract: A closing unit for a shaping machine includes mutually moveable mold mounting plates suitable for carrying mold tool portions, a first hydraulic cylinder adapted to apply a closing force to the mold mounting plates, a second hydraulic cylinder, and a pressure storage means connected to the first hydraulic cylinder and adapted to store a pressure prevailing in the at least one first hydraulic cylinder upon pressure relief as a storage means pressure. A hydraulic interconnection of the pressure storage means with the second hydraulic cylinder allows the storage pressure stored in the pressure storage means to be used for locking and/or unlocking the locking device.

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 device for a molding machine includes a first pump for a hydraulic fluid, a second pump for the hydraulic fluid, and a drive device for the first pump and the second pump. A first main conduit leads away from the first pump, and a second main conduit leads away from the second pump. A first consumer is connected with the first main conduit via a first opening and a first sub-conduit, and the first consumer is connected with the second main conduit via a second opening and a second sub-conduit. A second consumer is also connected with one of the main conduits via a third opening and a third sub-conduit. The second consumer is connected with the first main conduit via the third opening and the third sub-conduit, and is connected with the second main conduit via a fourth opening and a fourth sub-conduit.

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.

Abstract: A vertically closing closure unit for an injection molding machine includes a moveable mold mounting plate, and at least one frame bar for guiding the moveable mold mounting plate. A vertical restraint device holds and locks the moveable mold mounting plate to the at least one frame bar.
