Abstract: An apparatus for injection molding comprises an injection unit comprising a plunger, the plunger being translated with accumulation of plasticized material in preparation for injection and being advanced to inject the accumulated plasticized material into mold cavities. At least one electric motor is engaged with the plunger to resist translation as melt is accumulated and to inject plasticized material into the mold cavities. At least one hydraulic actuator selectably operates the plunger during a pack and hold interval to supply supplemental force when force supplied by the electric motors is limited to maintain the operation of the motors within the applicable continuous duty rating thereof. The electric motors are advantageously selectably operatively engaged with the plunger to inject plasticized material into the mold cavities and the hydraulic actuators are operated to inject plasticized material into the mold cavities when the motors are not engaged therefore.

Abstract: What is disclosed is an injection unit for an injection molding machine, comprising a screw which may be driven by means of a spindle drive. Driving of the spindle drive is effected by means of an electric motor. In addition, through the intermediary of a hydraulic cylinder a force acting in the axial direction is transmitted to the screw of the injection unit. In accordance with the invention, the electric motor drives a pump whereby a pressure chamber of the cylinder may be supplied with more pressure medium than is required in an axial displacement of the cylinder.

Abstract: An energy efficient drive system is provided for use on typical injection molding machines whereby a single electric motor drives both the extruder screw and a hydraulic motor that continuously charges a hydraulic accumulator during the extrusion process. During the injection cycle, the charge in the accumulator is directed to stroke the extruder screw and inject melt into the mold cavities. Another embodiment utilizes a similar arrangement on the clamp mechanism of the injection molding machine whereby the charge in the accumulator is directed to hold the mold closed during the injection cycle.

Abstract: A hybrid drive includes an electric motor coupled to a hydraulic drive having a double-acting hydraulic piston and a piston rod, and a substantially throttle-less valve for actuating the hydraulic drive, and a control unit for actuating the electric machine. To avoid unnecessary energy consumption, an actuating direction requested by the hybrid drive and a desired actuating force are determined, the valve is switched to a position such that the hydraulic drive is effective in the actuating direction, at least when the actuating force cannot be generated by the electric motor alone, the difference between the force generated by the hydraulic drive and the actuating force is determined, and the electric motor is operated such that the desired actuating force is achieved by adding the force generated by the motor to the force generated by the hydraulic drive, or subtracting the first from the latter.

Abstract: A hybrid injection unit for an injection molding machine includes a plasticizing screw having a shaft and constructed for rotation and axial displacement. Operatively connected to the shaft is a first electric motor for rotating the plasticizing screw, and a second electric motor for axial displacement of the plasticizing screw. A cost-efficient construction of the second electric motor and reduced stress of the linkage between this electric motor and the shaft is realized by providing at least one piston and cylinder unit in fluid communication with a pressure source for support of the second electric motor in injection direction, and a traverse acted upon by one end of the piston and cylinder unit and rotatably supporting the shaft of the plasticizing shaft. The traverse acts upon the shaft between a force introduction point of the second electric motor into the shaft, on one hand, and the plasticizing screw, on the other hand.

Abstract: A drive device which is intended for displacing two linearly movable components of a plastics injection-molding machine at least partly at successive times, in particular for displacing the injection unit for bringing the injection nozzle into contact with a mold and for displacing the injection mechanism for injecting polymer into the mold. With a known drive device, arranged downstream of an electric rotating motor are two clutches, by which rotational movements are transmitted on the basis of frictional engagement, and with which wear accordingly occurs. Each clutch is followed by a threaded drive, by which the rotational movement of the output element of a clutch is transformed into the linear movement of the machine component to be displaced. To make the known drive device for a plastics injection-molding machine less susceptible to wear and less costly in a first way the threaded drive is arranged between the electric motor and the two clutches and, for displacing the one movable component, the linearly movable drive output element of the threaded drive is able to be moved beyond the displacement distance necessary for displacing the other movable component. In a second way the electric motor is an electric linear motor with a linearly movable drive output element, arranged downstream of which in the force chains are the two clutches, and for displacing the one movable component, the drive output element is movable beyond the displacement distance necessary for displacing the other movable component.
