PROBLEM TO BE SOLVED: To provide an injection molding machine which effectively uses heat dissipated in a large quantity when an injection material which absorbs a large amount of energy and becomes in a molten state is solidified.SOLUTION: In an injection molding machine, molds (15, 16) are connected to a mold temperature regulating machine (30) by means of thermal medium supplying pipes (15a, 16a) and thermal medium returning pipes (15b, 16b). A heat exchanger (35) is interposed between the thermal medium returning pipes (15b, 16b). The air which is heated by the heat exchanger is supplied to a hopper (3) through a hot air supplying pipe (40) so as to preheat and dry injection material in the hopper. |
