ABSTRACT:
An injection molding machine includes an actuator supplied oil so as to actuate, an accumulator in which the oil, supplied to the actuator and having an accumulating hydraulic pressure set in a range of designated values, is accumulated, an accumulating hydraulic pressure determining part configured to determine whether or not the accumulating hydraulic pressure is sufficiently higher than an actuating hydraulic pressure that is a hydraulic pressure for actuating the actuator, and an accumulating hydraulic pressure change part configured to reduce a set value of the accumulating hydraulic pressure in a case where the accumulating hydraulic pressure is sufficiently higher than the actuating hydraulic pressure.
