PURPOSE:To enhance the degree of accuracy of monitoring by loading molten resin in the mold cavity, sensing the energy consumption during dwelling to judge if the value is within the specified range. CONSTITUTION:The value sensed by the sensor 6 for detecting injection ram pressure is converted to voltage by the voltage converter 8 for injection ram pressure, and the value sensed by the sensor 7 for detecting injection speed is converted to voltage by the voltage converter 9 for injection speed. The said two voltages are multiplied by the multiplier 10. Then, together with the start of injection, the integration starting trigger transmitter 12 starts, and the time integral of the product of the two voltages is started by the integrator 11. When the dwelling process is completed, the integration finishing trigger transmitter 16 starts to complete the integral action of the integrator 11 and the integration value is transmitted to the comparator 13. The comparator 13 compares the same with the range of value set by the reference range setting device 14, and the signal 15 is issued in case the value is out of the said set range. |
