Title (EN) PRESSURE GENERATING DEVICE AND USE THEREOF
(FR) DISPOSITIF GENERATEUR DE PRESSION ET SON UTILISATION
Abstract: front page image
(EN)A pressure generating device for use in injection moulding at a high pressure or normal pressure where the pressure generating device is attached to the mould, the platens, the tie bars or other suitable parts of the injection moulding machine which device operates separately from the normal pressure generating mechanism and acts on the content of the mould cavity only, said device comprising a pressure generating part, e.g. a hydraulic cylinder (1) connected with a plunger (2) which can bring the pressure inside the cavity to the desired level during an injection cycle and a non-return flow valve (3) or any other element closing the mold cavity from the injection side, and the use of said device in injection moulding at high pressure or normal pressure.
(FR)Un dispositif generateur de pression utilise dans le moulage par injection a haute pression ou a pression normale ou le dispositif generateur de pression est assujetti aux moules, aux plateaux, aux tirants ou autres pieces appropriees de la machine de moulage par injection, lequel dispositif fonctionne separement du mecanisme generateur de pression normal et agit sur le contenu de la cavite du moule seulement, ledit dispositif comprenant une partie generatrice de pression, p.ex. un cylindre hydraulique (1) cooperant avec un piston (2) qui peut amener la pression a l"interieur de la cavite a un niveau desire pendant un cycle d"injection et une soupape de retenue du debit (3) ou tout autre element fermant la cavite du moule du cote injection, et l"utilisation dudit dispositif dans le moulage par injection a haute pression ou pression normale.
