PROBLEM TO BE SOLVED: To provide a method for molding an injection-molded synthetic resin article which can simply and correctly mold the injection-molded synthetic resin article duplicated/integrated with a primary injection molding part by molding a secondary injection molding part of a large projected area by using one injection molding mold device and especially can correctly mold the article without making the primary injection molding part fall in a secondary molding cavity part even when the mold opening direction of the mold device is the transverse direction and the injection molding mold device. SOLUTION: A primary molding cavity part 12 is formed by advancing a slide core 4 in the transverse direction simultaneously with mold opening. Next, a first resin 13 is injected into the primary injection molding cavity part 12 to mold the primary injection molding part 11. Next, in such a state that the primary injection molding part 11 is held by a holding means 5, the slide core 4 is made to retreat to form the secondary injection molding cavity part 22. In the projected surface of the secondary injection molding cavity part 22 projected in the moving direction of the slide core 4, the size of the secondary injection molding cavity part 22 is set up to make the projected surface of the primary injection molding part 11 smaller than the projected surface be completely duplicate. Then, in such a state that the primary molding part 11 is held, a second resin 23 is injected into the secondary injection molding cavity part 22 to form the secondary injection molding part 21.
