PROBLEM TO BE SOLVED: To solve a problem of insufficient cooling by rapidly cooling moldings. SOLUTION: An injection molding die 1 is configured of a fixed part 2, a movable part 3 which can be clamped and opened with the fixed part 2 and an ejector mechanism 4 provided on the movable part 3. The fixed part 2 without the ejector mechanism 4 has an air introduction path 22 for making the outside of the die 1 communicate with a molding face. Consequently, it is possible to open the die 1 by a set interval by supplying compressed air into the path 22 under such a state that the movable part 3 is opened by a set interval and thereby guide the compressed air into a space formed between the movable part 3 and the fixed part 2. Thus the surface of moldings S can be directly cooled by the compressed air.
