Abstract

Machine for manufacturing hollow articles of synthetic thermoplastic material by an extrusion and blowing process, which is characterized by comprising an extrusion nozzle extended downwards and adapted to extrude a tubular body of said material in a state of softening by heat; a blower tube extended downwardly from the extrusion die coaxially thereto and which is made of a rigid, heat conducting material, and has a diameter markedly smaller than the diameter of the nozzle, so that the extruded body has no contact with the nozzle. The tube; at least one split mold, terminated at one end by a pair of jaws adapted to tightly grip a region of the body located below the lower end of the tube, while at its opposite end it has a pair of rubber pads adapted to hold another region of the body. body on the tube, by virtue of which the body section between the two regions can be expanded within the mold by means of compressed air supplied through the tube, said rubber pads being adapted to fully grip the other mentioned area of the body. body in the absence of the tube in said region; means for moving the mold along the tube and beyond the lower end of the latter on a closed path including a demoulding station; a stationary cam disposed over part of the trajectory beyond the demolding station; and perforating means incorporated in the divided mold and driven by said cam to pierce the wall of the expanded body within the mold in a region adjacent to said pair of rubber pads, thereby reducing the pressure inside the raw body before demolding it.
