PROBLEM TO BE SOLVED: To provide a continuous plasticizing type injection molding machine capable of preventing the occurrence of trouble such as the back flow of a plasticized resin or the like by discharging the plasticized resin in an accumulator device by detecting an abnormal rise in the resin pressure in the accumulator device. SOLUTION: This continuous plasticizing type injection molding machine is equipped with a continuous plasticizer 11 for plasticizing a synthetic resin material, the accumulator device 12 comprising the cylinder 30 communicating with the outflow passage 19 of the continuous plasticizer and the piston 31 provided in the cylinder and temporarily storing the plasticized resin supplied from the continuous plasticizer, an injection device 13 for metering the plasticized resin supplied from the accumulator device to inject the same, a pressure sensor 48 as a measuring means for measuring the resin pressure in the accumulator device and a discharge valve 47 as a discharge means for discharging the plasticized resin in the accumulator device when the resin of a set value or above is detected by the pressure sensor 48.
