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: An injection unit for a moulding machine includes an injection cylinder, and an injection piston is provided in the injection cylinder. During an injection process, the injection piston is configured to push out a plasticized mass—in particular plasticized plastic—from the injection cylinder and to feed it to a moulding tool via an injection nozzle. At least two plasticizing units and two supply channels are provided, and the at least two plasticizing units can be fluidically connected with the injection nozzle by the supply channels. The at least two plasticizing units are configured to supply the injection cylinder with the plasticized mass via the supply channels and the injection nozzle prior to the injection process.

Abstract: A plasticizing device includes a plasticizing cylinder and a plasticizing screw arranged in the plasticizing cylinder. The plasticizing screw is rotatable about, and linearly movable along, a longitudinal axis. The plasticizing screw comprises a functioning section. A sensor is arranged in or on the plasticizing cylinder, and a distance to the surface of the functioning section of the plasticizing screw can be measured by the sensor. A detecting device can detect a type of the functioning section and/or an operating state of the functioning section, can detect a distance signal progression by a movement of the functioning section relative to the sensor, can compare the detected distance signal progression with a stored distance signal progression, and can issue a signal representing the type of functioning section and/or the operating state of the functioning section depending on a matching of the detected distance signal progression with a stored distance signal progression.

Abstract: A pull or push rod or locking nut for a molding machine has an undercut, and the undercut has an undercut cross-section, a side wall, and an undercut ramp. The side wall transitions via a first transition curvature into an undercut base, and the undercut base transitions via a second transition curvature into the undercut ramp. The undercut base, viewed in the undercut cross-section, is at least partially designed as a curvature, and the curvature of the undercut base differs from the first and/or the second transition curvature.

Abstract: A pull or push rod for a molding machine having a groove. The groove is suitable for forming a positive-locking connection with a locking nut, by which positive-locking connection forces are transmittable between the locking nut and the pull or push rod. The groove has a groove cross-section, has at least two groove flanks, and has a groove base. The at least two groove flanks, viewed in the groove cross-section, each transition with at least one transition curvature into the groove base. The groove base in the groove cross-section is at least partially formed as a curvature, and the curvature of the groove base differs from the transition curvatures of the groove flanks.

Abstract: A method of manufacturing a molded part includes inserting melt into a cavity of a first tool part, and the first tool part and a second tool part are moved away from one another during or after the insertion of the melt by moving a mold clamping plate relative to a mold clamping plate such that in the first tool part or in a second tool part an at least partial clearance of a first or second zone of the cavity takes place, and a gap is formed between the first tool part and the second tool part. Melt is further inserted into the cleared area of the cavity, and the gap is bridged by an at least already partially solidified section of the melt. A holding force is transmitted from the second tool part through the partially solidified section of the melt bridging the gap to the first tool part.

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.

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 restraint device locks the moveable mold mounting plate to the at least one frame bar.
