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, further reducing a cooling time of the molded article, and enhancing efficiency of the injectio molding cycle, 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, and stops application of the voltage among the conductive parts, before the conductive material is fully filled in the cavity.SELECTED DRAWING: Figure 1 |
