PROBLEM TO BE SOLVED: To shorten the time of one cycle of molding from the heating to cooling of a die. SOLUTION: When cooling a die (1a, 1b) with a cooling unit (20a, 20b), a heating unit (10a, 10b) is evacuated from the rear surface of the die (1a, 1b), and a cooling unit (20a, 20b) is arranged at the rear surface of the die (1a, 1b). When heating the die (1a, 1b) by the heating unit (10a, 10b), the cooling unit (20a, 20b) is evacuated from the rear surface of the die (1a, 1b), and heating unit (10a, 10b) is arranged at the rear surface of the die (1a, 1b). Since the die can be efficiently heated to a required temperature in a short time while being able to cool the die to a required temperature efficiently in a short time, the time of one cycle of molding from the heating to cooling of the die can be shortened.
