ABSTRACT:
A screw-type resin injection apparatus for injection molding which includes a cylinder element having a cylinder chamber for receiving resin therein, and having, at an end portion, a nozzle for injecting the resin. A screw element is arranged within the cylinder chamber in a manner allowing rotation and axial movement. A rotary drive shaft is connected to the screw element telescopically so as to be capable of transmitting a torque. The rotary drive shaft is rotatively driven by a motor. A fluid pressure cylinder unit is arranged laterally of the cylinder element in parallel relation thereto. The fluid pressure cylinder unit is rotatably engaged with the screw element to drive the screw axially. Preferably, the screw element is provided with a mixing screw portion which has a screw groove small in pitch and large in lead angle and an axial groove extending axially.
