PROBLEM TO BE SOLVED: To provide the plasticizing moving device of an electromotive injection molding machine capable of controlling the nozzle touch pressure with high precision and high response by a simple constitution using a hydraulic actuator, and a nozzle touch method. SOLUTION: An injection device 2 is moved by a hydraulic cylinder 20 and a hydraulic pump 24 is driven by a servomotor 28. The driving of the servomotor 28 is controlled by a controller 26 and the oil pressure supplied to the hydraulic cylinder 20 from the hydraulic pump 24 is controlled and the movement of the injection device 2 and nozzle touch pressure are also controlled.
