PURPOSE:To heighten degree of freedom of a shape of a product, improve appearance quality, shorten a molding cycle, and apply to upsizing by letting slide cores approach and separate in a direction different from a mold clamping direction of a mold so as to form a cavity for secondary molding. CONSTITUTION:A primary cavity 33a comprises a primary core 35 of a primary molded piece and a die face of the primary molded piece and forms a primary molding space having the same shape as that of the primary core 35 and the primary molded piece. A primary driving means 45 is provided for moving the primary core 35 and the primary cavity 33a in approaching and separating directions so as to perform mold clamping and mold opening. A secondary cavity which corresponds to a secondary molded piece is provided being divided. Secondary slide cores 87 and 89 have the same shape as the entire shape of the secondary molded piece as a whole and form a secondary molding space to be connected to the primary molding space. Secondary driving means 91 and 95 perform mold clamping and mold opening by moving the slide cores in a direction different from the moving direction of the primary core 35 and the primary cavity 33a. |
