<p>The invention provides a control method of an injection moulding machine and the injection moulding machine, which can prevent molten resins from leaking between a nozzle and a nozzle contact part even though the forward instruction of the nozzle of a nozzle pressing mechanism is stopped. In the control method of the injection moulding machine (11) which is provided with a screw rod (32) or a plunger capable of moving forward and backward in a heating cylinder (31) of an injecting device (14), a nozzle (33) arranged in front of the heating cylinder (31) to injecting the molten resins, and a nozzle pressing mechanism (43) enabling the nozzle (33) to move forward and backward and being capable of abutting against and detaching from a nozzle contact part (36), the screwing up and off of the screw rod (32) can be realized when the forward instruction of the injecting device (14) stops or is stopped, or before the backward instruction starts under the state that the nozzle (33) abuts against the nozzle contact part (36).</p> |
