Abstract: An injection molding apparatus includes an electric motor, a torque variable mechanism that changes an output torque of the electric motor, and a screw driving unit that transmits the output torque of the torque variable mechanism to a feed screw, whereby the feed screw is turned by the electric motor, the torque variable mechanism and the screw driving unit. The torque variable mechanism applies, to the feed screw, a torque equivalent to a hydraulic drive. The electric motor is interchangeable with a hydraulic motor to enable the injection molding apparatus to change between electric and hydraulic drive of the feed screw.

Abstract: A method for operating a hydraulic drive apparatus in which flows of oil discharged from a plurality of hydraulic drive sources each using a hydraulic pump are merged in order to drive an actuator. At least in a pressure control mode, one of the hydraulic drive sources (main hydraulic drive source) is operated in a regular manner, and the other hydraulic drive source (auxiliary hydraulic drive source) is operated such that at A merge point where the oil flows merge, the pressure of oil from the auxiliary hydraulic drive source becomes lower than the pressure of oil from the main hydraulic drive by a predetermined amount. Thus, an ordinary pressure control signal is applied to the main hydraulic drive to perform an ordinary pressure control.

Abstract: An electric injection apparatus comprising a hydraulic cylinder for back pressure control. The electric injection apparatus includes rear and front supports integrally coupled to each other by a tie bar with a predetermined spacing therebetween. A heating barrel having an injection screw arranged therein is attached to the front support. Between the supports, a screw thrust member having an injection screw rotatably coupled to its front center is movably arranged so that the tie bar penetrates therethrough. Besides, the cylinder in the hydraulic cylinder is isolated from the heating barrel. This eliminates thermal effects and allows stable back pressure control in long-hour use.
