An injection molding machine in which injection units are arranged at any selected surface of a mold to perform an injection molding operation. The machine comprises a main injection unit, which has a main NC unit for controlling servomotors for thrusting and rotating a screw and moving an injection cylinder for each injection unit and for controlling servomotors for clamping the mold and ejecting the molded product, and a sub-injection unit, which has a sub NC unit for controlling only the servomotors for thrusting and rotating the injection screw and moving the injection cylinder for the respective injection unit. The main injection unit and the sub-injection unit is movable toward and away from a mold clamping unit. The main NC unit of the main injection unit controls the timing of operation of the sub-injection unit and controls the servomotors of the main injection unit and the mold clamping unit via a connector.
