PROBLEM TO BE SOLVED: To maximally lead out the maximum capacity possessed by the electromotor of an arm mechanism in consideration of the operational characteristics of the arm mechanism in a molded product ejector. SOLUTION: The control part 5 provided to the molded product ejector 1 is constituted so that a torque allowable width B having a definite width within a range not exceeding the rated torque X prescribed to the electromotor M3 is set, the torque of the load applied to the electromotor M3 during the automatic operation of the molded product ejector 1 is always monitored to operate the average torque value A within a definite time including the drive time and stop time of the electromotor M3, the torque at the time of acceleration and deceleration is reduced when the electromotor M3 is driven at the time of next ejecting operation in a case that the average torque value A exceeds the upper limit value B1 of the torque allowable width B and the torque of the electromotor M is controlled so as to increase the torque at acceleration and deceleration when the electromotor M is driven in next ejecting operation in a case that the average torque value A is less than the lower limit value B2 of the torque allowable width B.
