PROBLEM TO BE SOLVED: To provide an injection molding device and an injection molding method, capable of suppressing extension of an injection molding cycle, suppressing occurrence of appearance defect of a molded article, and in addition, determining easily an insulation property deterioration state of the molded article, when a conductive material is injection molded.SOLUTION: A molding die comprises plural conductive parts which are insulated each other on at least a part of a cavity formation plane. The injection molding device comprises: energization means for applying predetermined voltage among the conductive parts; and energization control means for controlling the voltage applied by the energization means. The energization control means applies the voltage among the conductive parts by the energization means so that, the injected conductive material is energized and heated when it contacts the conductive parts of the molding die. The injection molding device further comprises: measurement means for, measuring a parameter value related to electric resistance among the conductive parts in a state in which, the conductive material is not filled in the molding die; and insulation property determination means for determining an insulation state among the conductive parts, based on the parameter value.SELECTED DRAWING: Figure 1 |
