    摘要： An electric injection molding machine capable of maintaining a quality of molded articles and capable of suppressing a variation of weight of articles molded by a mold having a plurality of cavities when transferring molding conditions in a hydraulic injection molding machine as they are to the electric injection molding machine. This electric injection molding machine has an electric injection mechanism for injecting a molding material into a mold by a drive force of an electric motor, an injection control unit and a servo driver for controlling the injection motor so as to follow the injection speed reference, and an reference compensation unit for compensating the injection speed reference based on the characteristics of the hydraulic drive system so that fluctuation characteristics of the injection speed with respect to the injection pressure when controlling the electric injection mechanism approximate the fluctuation characteristics of the injection speed with respect to the injection pressure in the hydraulic injection mechanism performing the injection of the molding material to the mold by the hydraulic drive system.

    摘要： The retreat completion position of the screw in the charging step in actual production is controlled based on the result in pilot production as follows. In pilot production, the measurement value Ts of the screw driving torque is integrated with respect to the screw position P from the forward limit to the retreat completion position Ps. When conforming item is produced in the pilot production, the value &Sgr;Ts·dP obtained as a result of the integration is stored as a reference value. After actual production begins, the measurement value Tx of the screw driving torque is integrated in real time with respect to the screw position P from the forward limit to the screw position at each time. The obtained value &Sgr;Tx·dP is monitored. When this value &Sgr;Tx·dP coincides with the reference value &Sgr;Ts·dP, it is determined that the charging step has been completed, and the retreat operation of the screw is stopped.

    摘要： The duty of a current to be supplied to an injection motor is calculated on the basis of the ratio between set injection time for which the injection motor operates and molding cycle time, a shaft torque of the injection motor is calculated on the basis of a set maximum injection force of the injection molding condition, a maximum current for the injection motor is determined on the basis of the calculated shaft torque, and it is decided that the injection motor is overloaded, an alarm is given, a duty for a current that enables continuous molding is retrieved for the maximum current, a state that enables continuous molding is displayed and the molding cycle time determining the duty of the current that enables continuous molding is corrected when the current having the calculated desired duty is smaller than the maximum current.
