PURPOSE:To reduce the cost of whole device by a method wherein a driving power source is connected through a simple amplifier to degating units provided with an ultrasonic oscillator adapted to each of a plurality of extractors and those are switched and driven. CONSTITUTION:When molded parts extracted sequentially by a plurality of injection molded part automatic extractors R1...Rn are pressed against the horns of degating parts Rb1...Rbn instruction signals is for instructing the supply of a driving power source are outputted by a detector to distribution control circuits DIS. A distribution control circuit DIS outputs a drive signal DS to a drive circuit DC on the basis of an inputted instruction signal IS and simultaneously an output indicating signal is outputted to the amplifier AMP, the amplified driving power source VD is supplied to a corresponding converter COV, the timer converter set by a timer circuit T is operated to act an ultrasonic oscillation on a molded part through the phone. After the course of a preset time a finish signal FS is outputted to the distribution control circuit DIS. |
