Abstract

SUMMARY OF THE INVENTION The present invention relates to an apparatus for the manufacture of hollow articles made of plastics and having an internal lowering device, the apparatus having at least one pressing unit having a molded upper tool portion and a negative lower die part adapted to the vertical axis of the upper mold part, and furthermore, for making the product press, the two tool parts are open, i.e. wherein the amount of plastic required to compress a product is added to the negative lower tool portion, and mutually to operate between the closed position, and in the open position of the press tools to remove the pressed finished article, the upper tool portion is provided with a movable member in the sleeve forming the peeling tool to remove the pressed product in the open position of the press tools. The device according to the invention is characterized in that the piston (34) has a movable tube (30) and a pin (3) located within its annular axis within the tube (30), wherein the tube (30) is provided with an end (32) provided with annular nozzles. , the oscillating elements (41) on the periphery of the elements are provided with radial planes in the form of radial planes, which have additional grooves (45) for the underside of the elements, the oscillating elements (41) of the sleeve (3) in the closed state of the extruder (41) and the tube (30). ), together with the end of the die, the elastic member necessary for pressing the articles, and the openings in the open position, the elements being held in position, and the product being removed from the grooves (45) to remove the product by the peeling tool (30).
