PROBLEM TO BE SOLVED: To simultaneously perform split molding of a hollow molding and integration of split moldings by combination of a rotary mold and a fixed mold by split molds. SOLUTION: A rotary mold 13 having two molding recesses 11, 12 aligned on both opposed surfaces of a fixed plate and a movable plate 2, and a fixed mold 16 having one molding protrusion 14 are alternately disposed so that the one recess 12 of the mold 13 is superposed to be disposed at a center and the other recess 11 is superposed to be disposed at the protrusion 14 to generate a pair of cavities 17, 18 for split molding a hollow molding 30. Resin is injection charged in the cavities 17, 18, and split moldings are molded. After the mold is opened, both the rotary molds are rotated, the split moldings are moved to the center. They are superposed by closing the mold, the resin is injection charged in a cavity 19 of superposed periphery, and a connecting part for integrating the split moldings with the molding 30 is formed. |
