射出成形機
Document Type and Number:
Japanese Patent JP6791948
Kind Code:
B2
Abstract:
An injection molding machine provided with: a nozzle that touches a metal molding device and injects a molding material inside of the metal molding device; a heater that heats the nozzle; a temperature detector that detects the temperature of the nozzle; a control device that calculates the output of the heater on the basis of the detected temperature of the nozzle and the set temperature of the nozzle, and controls the heater using the obtained output; and a moving device that deploys and retracts the nozzle with respect to the metal molding device. The control device estimates the change in temperature of the nozzle resulting from the displacement of the nozzle, and, in order to suppress the change in temperature, corrects the output on the basis of the estimated change in temperature, and controls the heater using the corrected output.
