PURPOSE:To make it possible to reduce the wall thickness of the neck of a hollow molded article, such as a bottle or the like, by previously blow-molding the neck of an injection-molded parison with bottom using a split die while regulating the temperature, and then moving the parison to an orientation blowing mold to form a body. CONSTITUTION:An injection-molded bottled parison 4 is housed in a temperature- regulating pot 2. Split die halves 3, 3 are closed, and air is blown thereinto to mold a neck 4a of the parison 4. Then, the parison 4 is moved to a blowing mold 10. While the molded neck 4a is airtightly maintained, an orientation rod 13 is inserted into the blowing mold 10, and air is blown thereinto to form a main body part of a hollow molded article. |
