PROBLEM TO BE SOLVED: To provide a device for manufacturing an injection-molded polyamide resin product with such advantages that the temperature adjustment and the temperature control of a molding die are easy and a plate-like molding can be easily released from the molding die, and a method for manufacturing the injection-molded polyamide resin molding. SOLUTION: This device for manufacturing injection-molded polyamide resin molding is a device for manufacturing the polyamide resin molding by anionic polymerization of a polymerizable lactam liquid in a molding die. In addition, the device consists of a fixed molded body 2 equipped with a plate-like molding 4 having an internally provided oil passage for flowing a heat medium oil, a movable molded body 3 equipped with plate-like molding 4 having a likewise internally formed oil passage for flowing the heat medium oil, a spacer 5 which forms a space area for injection-molding the polymerizable lactam liquid, interposed between the fixed molded body 2 and the movable molded body 3, and a device for circulating the heat medium oil which adjusts the temperatures of the heat medium oil and at the same time, feeds the heat medium oil to the plate-like molding. |
