Abstract

PURPOSE:To ensure mold releasing by the operation of a knockout pin, by a method wherein a temporary holding pin for piercing forming is arranged at and projected from the top end of a neck flash portion of a recessed inside surface of one half of a split mold, in a rotary blow molding machine. CONSTITUTION:A split mold 70 is placed in each of mold stations 28 arranged at regular intervals along the outside peripheral surface of a rotor 24 of a rotary blow molding machine A. The mold 70 consists of right and left halves 66, 68, with an inside knockout pin 72 placed in a knockout pin hole 74 is such a manner that it can be projected and retracted. A temporary holding pin 80 for piercing forming directed perpendicularly to the pin 72 is arranged at the head end 76a of a neck flash portion beta.
