The barrel temperature control apparatus for an injection molding machine can execute the barrel temperature control in such a way as to optimize the disturbance suppression characteristics. The temperature control section 7 comprises the manipulated variable addition and subtraction section 14 at the rear stage of the PiD control section 12 in such a way that the barrel temperature of the injection molding machine 1 can be controlled under both feedback and feed-forward. Further, when the same products are molded continuously, the barrel temperature is feed-forward controlled on the basis of the learned change manipulated variable.
