PURPOSE:To maintain the energy consumption always constant and stabilize the quality of molded part by sensing the energy consumption required for filling molten resin in the mold cavity and issuing a signal when the value of consumption reaches the reference value. CONSTITUTION:The value sensed by the sensor 6 for detecting the injection ram pressure is converted to voltage by the voltage converter 8, while the value sensed by the sensor 7 for detecting injection speed is converted to voltage by the voltage converter 9 for injection speed, and both are multiplied by the multiplier 10. Together with the signal issued by the integration starting trigger transmitter 12, the time integral of the product for the said multiplied value is started by the integrator 11. At the same time, the integral value is compared with the value, presetted by the reference value setting device 14 by the comparator 13, and the signal 15 is issued at the time the said two values coincide. by the said signal 15, switchover to the dwelling process, or change-over of injection speed, one of the controls of injection process, can be carried out. |
