<P>PROBLEM TO BE SOLVED: To suppress deterioration in quality of molded articles and early deterioration of a mold 21, comprising a plurality of split molds (a fixed mold 21a, a movable mold 21b), by minimizing the temperature difference between the split molds of the mold. <P>SOLUTION: A mold temperature control device is configured to make the following temperature control part of a plurality of temperature control parts as a main control part, that is, a temperature control part which has the worst rising characteristics of the detected temperature of a split mold resulting from execution of temperature control when the target temperature is changed step-by-step or a temperature control part which has the largest fluctuation range of the detected temperature resulting from the execution of the temperature control when the target temperature is constant, while using the other temperature control part as a follow-up control part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
