Abstract

La présente invention concerne une machine à couler sous pression à tambour entièrement automatique utilisant une alimentation fermée et une fonte sous vide. Un élément de moteur (18), un moule mobile rotatif (1) et un moule mobile fixe sont montés sur un support. Un évidemment concave-convexe (22) du moule mobile rotatif et un évidemment concave-convexe du moule mobile fixe sont combinés afin de former une cavité de coulée. Un four de fusion sous vide (3), un réservoir d'huile à température constante (14), une extrudeuse de matériau en fusion (8), un réservoir hydraulique (12), une pompe hydraulique (21) et une tige de poussée sont placés à côté du support. Un appareil chauffant (9) est monté sur l'extrudeuse de matériau en fusion. Une entrée de matériau en fusion (7), un tuyau de sortie d'alliage liquide (4) et un tuyau d'entrée de gaz inerte (6) sont montés sur le four de fusion sous vide. Le tuyau de sortie d'alliage liquide est relié à une tête d'injection de métal liquide (27). Un tuyau de sortie d'huile à température constante du réservoir d'huile à température constante est en communication avec une chambre interne du moule mobile rotatif et une chambre interne du moule mobile fixe. La machine à couler sous pression entièrement automatique empêche l'oxydation de l'alliage liquide et la pollution de l'air par l'alliage liquide, ce qui permet d'améliorer l'efficacité de production et la qualité de produit tout en réduisant les coûts de production et la consommation énergétique.
