PROBLEM TO BE SOLVED: To provide a resin molding method capable of making it hard to damage the thin-walled part of a molded product in spite of a simple structure to demold the molded product. SOLUTION: After a mold 1 is opened, a movable core 4 is pressed and driven by the movable core plate 3 allowed to cooperate with the driving of a knockout pin plate 2 to demold the molded product 6 molded in the cavity 5 of the mold 1 by the movable core 4. A knockout pin 7 is pressed and driven by further driving the knockout pin plate 2 to press the molded product 6 demolded by the movable core 4 to detach the same from the movable core 4. After the molded product 6 molded in the cavity 5 of the mold 1 is demolded by the movable core 4, the molded product 6 is pressed by the knockout pin 7 to be detached from the movable mold 4 to eliminate the friction of the molded product 6 with the inner surface of the cavity 5 when the molded product 6 is pressed by the knockout pin 7 to reduce the resistance of the molded product 6.
