Abstract
A blow molding apparatus for the production of articles of thermoplastic material, characterized by an extrusion die to form said tubular mass of thermoplastic material, blow mold sections, adapted to be brought into contact with the tubular mass, forming said mold sections to said pair of blow molding cavities, when they enter into each other, one of the molding cavities having the configuration of one of said parts of the article and the other mold cavity having the configuration of the other part of the article, taking said mold sections with the tubular mass on opposite sides thereof to tighten or compress and weld said tubular mass between said cavities, and means for introducing fluid into the hollow compartments of the tubular mass that they are found in each molding cavity, to expand them and bring them into agreement with the respective cavities.
