An injection molding machine includes: a fixed side member; and a movable side member fixed to the fixed side member, the movable side member being driven by a motor in order to perform injection molding of a molded product. The injection molding machine further includes a power feeding apparatus, one or more motors, and at least one servo amplifier. The power feeding apparatus converts a three-phase AC voltage into a DC voltage. The one or more of the motors are provided in the movable side member and drive the movable side member. The at least one servo amplifier is provided in the movable side member and drives one of the one or more of the motors by the DC voltage being supplied thereto through a DC power supply line.

An apparatus for taking out a molded product is provided, the apparatus being capable of suppressing displacement vibration of an attachment mounted at a leading end of each of one or more approach frames by active control using one or more electromagnetic actuators. The apparatus includes an active vibration suppressing system. One or more electromagnetic actuators are mounted to the attachment of each approach frame or each approach frame.

An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller performs active control in conjunction with the positioning, control by the servomotor. At the beginning of the active control, the positioning control is primarily performed by the servomotor, and then the active control is positively performed by the active controller using an electric actuator. Compared with when only the active control is performed for vibration suppression, a lighter and smaller electric actuator can be employed.

An apparatus for taking out a molded product that is capable of suppressing displacement vibration of an attachment in a shorter time than ever without using a large-scaled electric actuator. An active controller starts active control after the amplitude of displacement vibration of the take-out head as an attachment has been attenuated to a predetermined setting by means of positioning control by a servomotor or when the amplitude can be considered as having been attenuated to the predetermined setting. The positioning control is first performed by the servomotor, and then the active control is performed by the active controller using an electric actuator which is light in weight and small in size.
