Abstract
DISPOSITIF DE FERMETURE HYDRAULIQUE POUR MACHINES DE MOULAGE PAR INJECTION, PRESSES, ETC., QUI COMPREND UNE OU DEUX PLAQUES DE MONTAGE 4-7 SUR LESQUELLES ON FIXE LES DEUX MOITIES 8, 8 D'UNE FORME OU D'UN MOULE, ET QU'ON DEPLACE POUR FERMER ET POUR OUVRIR CE DERNIER. LE DISPOSITIF COMPREND UN PISTON DE FERMETURE 5 SE DEPLACANT DANS UN CYLINDRE HYDRAULIQUE 1, ET QUI EST RELIE A UN PLATEAU DE SERRAGE 7 PAR DES TIRANTS 6. UN CONDUIT DANS LEQUEL SONT INTERCALES UN CLAPET DE NON-RETOUR ET UN ORGANE D'ETRANGLEMENT 24-25, 24-25 RELIE CHACUNE DES DEUX CHAMBRES DU CYLINDRE SITUEES DE PART ET D'AUTRE DU PISTON DE FERMETURE A UNE VALVE DE COMMUTATION 20 OU D'INVERSION QUI EST RELIEE AUSSI A UNE POMPE ET A UN RESERVOIR. EN OUTRE, SUR LE COTE DU PISTON DE FERMETURE 5 SUR LEQUEL S'EXERCE LA PRESSION DE FERMETURE EST FIXE UN PISTON-PLONGEUR 13 SOUS LA FORME D'UN PROLONGEMENT INTERIEUR DANS LEQUEL PEUT ETRE INTRODUIT UN FLUIDE SOUS PRESSION. LA VALVE DE COMMUTATION 20 PERMET D'INTRODUIRE OU D'EVACUER ALTERNATIVEMENT LE FLUIDE SOUS PRESSION DES DEUX CHAMBRES DU CYLINDRE.
