Abstract
An injection molding apparatus is on the basis of a hydraulic injection molding device, and the apparatus includes an electric motor, a torque variable mechanism that changes output torque by the electric motor, and a screw driving unit that transmits the output torque by the torque variable mechanism to a screw. The screw is turned by the electric motor, the torque variable mechanism, and the screw driving unit. The torque variable mechanism applies, to the screw, torque equivalent to a hydraulic drive.
