Abstract

PURPOSE: To contrive to improve the strength of a baffle plate, preventing the root portion of the baffle plate from the thinning thereof by projecting a baffle molding member, after a parison has been caused to lie parallel with the inner surface of a mold.
CONSTITUTION: First, a baffle molding plate 4 is retracted, shortening a driving cylinder 5, and at this state, a parison 6 is pushed out. The parison 6 is caused to lie parallel with the inner surface of a mold 3, and before its solidification by cooling, when the baffle molding plate 4 is projected into the mold, extending the driving cylinder 5, the parison 6 is stretched in the internal direction of the mold, and a baffle plate 6c is molded. Thus, after the parison 6 has been caused to lie parallel with the inner surface of the mold 3, the baffle molding plate 4 is projected, whereby the root portion 6d of the baffle plate 6c may be prevented from the thinning of its wall thickness, and the strength of the baffle plate 6c is improved.
