ABSTRACT:
An injection stretch-blow molding machine for producing hollow articles such as bottles by simultaneously performing the formation of a parison by injection molding and sharping of the parison by stretch-blow molding. The machine has an injection mold constituted by a male mold part and a female mold part and a stretch-blow mold constituted by a male mold part and a female mold part. The machine further has four neck molds capable of opening and closing to release and clamp the neck of the parison and arranged on a rotary body at a 90.degree. interval. The rotary body is rotatable to bring the neck molds successively through an injection position, heating position, blow position and a discharge position which are arranged at a 90.degree. interval. As the rotary body makes the 90.degree. intermittent rotation, the parison formed by injection in the injection position is brought by the neck mold to the heating position, and the preceding parison heated in the heating position is conveyed by another neck mold to the blow position to be finished by stretch-blow molding. At the same time, the finished article is conveyed by still another neck mold to the discharge position where the neck mold is opened to release the finished article.
