ASPIRED PIPE AND PINCEE AND METHOD OF MANUFACTURING THE SAME

摘要

The invention relates to the manufacture of liquid transfer lines used in the field of motor vehicles and trucks. In particular, the invention relates to the manufacture of supply chutes for liquid transfer, and in particular filling troughs for windshield washer reservoir. The object of the invention is a method of manufacturing a chute (3) in a mold having an upstream opening (701) and a downstream opening (702), the method of extruding a tubular parison (740) into the molded by the upstream opening (701), to blow gas through an opening to allow the parison to attach to the wall of the mold and to draw the gas through the other opening (702), the mold comprising at least two trolleys (722, 723) each being provided with an imprint corresponding to a portion of the pipe and at least one protuberance (4) and that when the gas is blown into the mold, the trolleys are separated from each other. other so that a bubble of parison material is formed between the carriages, and that once the bubble is formed, the carriages are brought together to mold the portion of the tube and the protuberance the mold being closed during blowing / suctioning and molding of the protuberance (4).
