Abstract
An apparatus for controlling a heating temperature which does not need to memorize compensation data preliminary but promptly corresponds to the temperature fluctuation in accordance with the running condition to thereby control the temperature accurately and stably. The control device 10 controls a heating state of the heater 4 corresponding to setting and a running state of the injection mold machine 1 heated by the heater 4. The injection mold machine 1 is adapted to run as expected and the temperature of which is maintained at a predetermined value by the heater 4. The mean value calculation and memory portion 20 functions to calculate a mean value of control inputs throughout a certain operating state. When the setting of the control device 10 is altered, the injection mold machine 1 requires another heating condition due to a change of operating state thereof. Two of the mean values corresponding to the alteration are selected and used in a certain calculation, so that the calculated result as compensating input is added to the control input.
