Abstract

PURPOSE:To provide the titled device capable of stretching and blowing uniformly by a method wherein male molds for injection molding and male mold for blow molding are provided alternately on four side surfaces of a rotary body, and a heater for heating parisons on the male molds for blow molding is provided so that it can be advanced and retracted in a direction perpendicular to a mold opening-closing device. CONSTITUTION:A female mold 4 for blow molding and a support 7 are provided so that they can be advanced and retracted relative to a female mold 2 for injection molding, the rotary body 9 is supported on the support 7 so that it can be intermittently rotated by 90 deg., and the male molds 12 for injection molding and the male molds 14 for blow molding are provided alternately on the four side surfaces of the rotary body 9. The male mold 14 for blow molding is composed of a core member 17 and a core rod 18 for blowing, and the heater 15 for heating the parison on the male molds 14 is provided so that it can be advanced and retracted in the direction perpendicular to the opening-closing direction of the mold.
