Abstract

L'invention appartient au domaine de la fabrication d'articles par coulée et notamment au domaine de la coulée sous pression de métaux et d'alliages; elle peut s'utiliser dans la fabrication de plastiques. La machine de coulée sous pression comprend des plaques mobile et immobile, reliées entre elles par des colonnes, et un dispositif d'orientation à rotor. Le dispositif d'orientation à rotor comprend un cadre à plaque (5) monté sur les colonnes de la machine et relié à la plaque mobile au moyen par des tringles réglables, et un mécanisme de direction. La machine comprend un moule à pression, constitué d'une partie mobile détachable, d'une partie médiane orientable (14) et d'une partie fixe. La partie médiane orientable (14) est montée dans le cadre à plaque (5) réalisé démontable. Le mécanisme d'orientation se présente comme une table orientable (7) disposée sur un axe vertical (6) monté à demeure dans le cadre à plaque. La partie médiane du moule à pression est montée sur la table orientable (7) de façon à pouvoir pivoter autour de l'axe vertical (6). La table orientable est actionnée par un entraînement (8). L'invention permet de simplifier la structure du dispositif et de rendre plus aisé la maintenance de celui-ci.
