PROBLEM TO BE SOLVED: To provide a high precision product with a restrained cost by making a mold to allow primary and secondary moldings simultaneously in one mold in a production process of a secondary molding. SOLUTION: In a first operation, a movable molding die 10 comes to a product shaped section 7 in a primary fixed side and a primary molding 12 is molded, and a movable molding die 11 comes to a product shaped section 8 in a secondary fixed side after inserting an insert member 9, mold clamped and a secondary molding 13 is molded. In a second operation, a movable side mold 2 is rotary moved 180°around a rotation axis 6 by a driving device 5 prepared beforehand in the movable side mold 2 after mold opening; thereafter the movable molding die 11 comes to the product shaped section 7 in the primary fixed side and the primary molding 12 is molded, while the movable molding die 10 comes to the product shaped section 8 in the secondary fixed side after inserting the insert member 9, mold clamped and the secondary molding 13 is molded. The first and second operations are repeated alternately by a reciprocal 180°rotation move of the driving device 5. COPYRIGHT: (C)2011,JPO&INPIT
