Definitions

  • blow molding machines for producing hollow plastic articles include at least one mold having a mold cavity with the shape of the article to be produced, the mold being adapted to be opened and closed.
  • the mold is opened to receive a preform or parison and then closed.
  • compressed air is introduced into the parison contained within the mold through a compressed air feed inlet and a corresponding feed nozzle to carry out the blowing of the parison which is expanded and conformed to the inner wall of the mold cavity to acquire the desired shape.
  • the blow molding machine includes at least one nest or dolly, divided in two sections, that holds the article after being blown and when it has been released by the mold.
  • the machine further includes trim tooling for removing the flash from the article.
  • the machine includes several feed lines for supplying cooling water to the mold and lines for supplying compressed air to the nozzles.
  • the advantages are represented by the very easy and fast replacement of molds and associated tooling due to the fact that the number of operations and adjustment to be carried out is drastically reduced; to the fact that such a replacement can be also performed by nonspecialized personnel, resulting in significant reduction in the operative costs of the working station; and by the fact that automation of the mold replacement is possible especially in the case of machine for high capacity production.
  • FIG. 1 is a perspective view of a modular tooling assembly for quick change of molds, including a mold having a single air feed inlet, with the mold shown in the closed condition;
  • FIG. 2 a perspective view of the modular tooling assembly for quick change of molds of FIG. 1, but with the mold shown in the open condition;
  • such a support 40 is made up with a frame including a removably mounted plate 41 which is connected at the top to a fixed part or section 100 of the machine, and at the bottom to four vertical rods 44 for guiding another plate 42 on whose back 410 there is the head of the stem of a corresponding operating cylinder 110 having a vertical axis, the lower side 420 of which is in contact with the base of the nozzle 4 so as to allow the actuation, that is the insertion into and the withdrawal from, the compressed air feed inlet 20 of the mold 2.
  • a third plate 43 equipped with a guide boss 45 for the stem of the nozzle 4 is fixed to the lower ends of the above- mentioned vertical rods 44.
  • the position of the nozzle 4 with respect to the compressed air feed inlet 20 of the corresponding mold 2 is preset. In other words, it is adjusted before the modular assembly 1 and the support 40 are assembled on the machine.
  • the number of compressed air inlets 20 of a mold 2 and associated blowing nozzles 4 may vary according to the size and shape of the item being manufactured.
  • the plates 10 which support the mold 2, the nest 5 and the trim tooling 6 are equipped with two connectors 21 for the quick connection of the water lines to the cooling water system.
  • the plates are also equipped with several parallel, transversely extending plugs or guide rods 11 which represent elements of guidance and linkage to corresponding drive means 70 that moves the plates 10 apart and together.

Abstract

L'invention concerne un outillage permettant le serrage rapide de moules ainsi que les accessoires associés utilisés dans une machine pour l'extrusion-soufflage d'articles en plastique creux ou d'articles tels qu'un moule (2) qui peut être ouvert. Ledit outillage comprend un orifice d'alimentation (20) servant à introduire de l'air comprimé, un injecteur d'air (4) dans lequel passe l'air comprimé, une poche (5) servant à tenir l'article (31) après qu'il ait été produit et libéré par le moule, un dispositif d'ébarbage (6) destiné à enlever les bavures (32), le moule, la poche et le dispositif d'ébarbage étant supportés par deux plaques de support (10) opposées parallèles et formant un ensemble modulaire (I) déplaçable longitudinalement par un chariot correspondant (50). De plus, l'injecteur d'air permettant d'introduire de l'air comprimé dans le moule est monté sur un support mobile autoporteur (40).
