Abstract: A method of controlling an injection molding machine by use of nozzle resin pressures in which resin is directly controlled to thereby enable highly accurate control, and a conventional mold can be utilized as it is. After metering a dose of resin, a resin pressure at the upstream side of a nozzle switching valve (12) is detected while the nozzle switching valve (12) is kept closed, and a pre-load is applied on the resin by controlling an injection cylinder (19). Subsequently, the nozzle switching valve (12) is opened, and injection of the resin is performed, then applying a dwell pressure on the resin in the mold. During the injection and dwell pressure application steps, a resin pressure at the downstream side of the nozzle switching valve (12) is detected, and the injection cylinder (19) and the nozzle switching valve (12) are controlled. In these steps, the resin to be filled is directly controlled, and therefore, the control can be carried out highly accurately. After the dwell pressure application step, the nozzle switching valve (12) is closed. Then, the resin pressure at the upstream side of the nozzle switching valve (12) is detected, and a back pressure is applied on the resin at the front end of a screw feeder (2) by controlling the injection cylinder (19).
