[Problem] To obtain good quality molded articles by preventing defective molding that results from bending of a mold plate that mounts a stationary mold on a stationary die plate. [Solution] An injection molding machine 1 in which a stationary mold 5 is mounted on a stationary die plate 4 via a relatively thin-walled mold plate 18, wherein: an injection unit 2 is advanced by rotating nut bodies 13 using the driving of a nozzle touch motor 16 to advance the nut bodies 13, which are screwed together with ball screw shafts 12; and, in order to make an injection nozzle 8 configured on the injection unit 2 to touch the stationary mold 5 with a strong nozzle touch force when a movable mold 7 is clamped to the stationary mold 5 and the injection nozzle 8 is nozzle-touched to the stationary mold 5 and to make the injection nozzle 8 to touch the stationary mold 5 with a weaker nozzle touch force than the nozzle touch force during mold-clamping when the movable mold 7 is retracted and the mold is opened, a control mean
