Abstract
L'addition concerne un dispositif de fermeture de moule de machine de moulage par injection dont le demi-moule mobile 30-31 est serré contre le demi-moule fixe 28-29 par des cylindres hydrauliques 64-66 entre une plaque de serrage mobile 31 portée par les tiges de pistons 50 des cylindres hydrauliques et une plaque de serrage fixe 52 portée par le pied de la machine et munie de paliers d'appui 63 pour lesdites tiges de pistons, prolongés de la profondeur du demi-moule fixe, la plaque de serrage mobile 31 étant constituée par la plaque d'éjection, afin de diminuer les contraintes de flexion sur les tiges de pistons, et épaulée à des éléments 60 joints amoviblement à l'extrémité libre de chaque tige de piston Le dispositif réduit le poids de la partie mobile et facilite l'accès au moule.
