摘要： White noise is applied to a servocontrol system of a servomotor in order to measure a frequency characteristic of a mechanical component in an electric injection molding machine, and a signal from an encoder is applied to a fast Fourier converter. Data from the fast Fourier converter is applied to a memory unit, and the content of the memory unit is displayed on a display unit in the form of a board diagram. Repair announcement is issued when a deviation of the resonant frequency of each mechanical component with respect to data at an initial setting time exceeds a predetermined value.

Behind the intermediate plate, two linear motor units are connected in parallel and arranged around the shaft of the screw to form axial symmetry. The output shafts of the linear motor units are connected to the tail end of a driving shaft through a common connecting arm, and the leading end of the driving shaft is fixed to the rear surface of the intermediate plate. Each of the liner motor units is constituted by a plurality of voice coil linear motors connected in parallel. Each of the linear motor units can be independently controlled. Voice-coil linear motors to be used are selected according to the type of product to be manufactured.

摘要： A mold fastening device has a fixed die plate, a rear plate, a movable die plate that can move back and forth, a toggle mechanism, and a drive motor that drives a cross-head. The position where the cross-head should be stopped is associated with the rate at which to accelerate the cross-head from that position or the rate at which to decelerate the cross-head to that position. The cross-head is operated at an acceleration that corresponds to that position. The drive motor is thereby driven at a constant output torque, regardless of the position of the movable die plate. Further, the time for opening and closing metal molds can be shortened.
