  • Device for controlling operation of injection molder
    Patent number: 4833616
    Abstract: A device for controlling the operation of an injection molder is disclosed. A fall detection signal is produced when a product falls from the mold. If the full detection signal is generated before the lapse of a fixed time preset in a timer from the instant of appearance of a mold-opening signal from a mold-opening signal generator, the next molding cycle is started. If no fall detection signal is generated within the preset time of the timer, an alarm is generated.
