PURPOSE:To conduct stretching blow molding continuously by a method wherein necked molds are linearly moved concurrently and sequentially through an injection molding part, a temperature regulating part, a stretching blow forming part and a mold releasing part, and the necked mold passed through the mold releasing part is circulated to the injection molding part. CONSTITUTION:The neck molds 2 are placed in each of the injection molding part A for a parison, the temperature regulating part B for the parison, the stretching blow forming part C for the parison and the mold releasing part D for a hollow molded article, and are linearly moved concurrently and sequentially through the parts. Molding, forming, mold releasing and the like are conducted at each of the parts when the necked mold is stopped at the part, and the necked mold having undergone the mold releasing operation is circulated to the injection molding part A side through a transfer passage 3 during a molding and forming period. |
