Title:
METHOD FOR POURING MOLTEN METAL IN VERTICAL SQUEEZE CASTER AND SLEEVE FOR PRESSURIZING FEED OF MOLTEN METAL
Document Type and Number:
Japanese Patent JP3096157
Kind Code:
B2
Abstract:
PURPOSE: To shorten a time from pouring molten metal into a sleeve until starting pressing of the molten metal into a mold by arranging a bottom plug at the lower end of the sleeve for pressing and executing the pouring of the molten metal into the sleeve for pressing at the position apart from a pressurizing plunger.
CONSTITUTION: The sleeve for pressing composed of a cylindrical body 1 and the bottom plug 2 is arranged below a crucible 3, and by operating a nozzle stopper 4, the molten metal 5 in the crucible 3 is poured into the sleeve. The sleeve is shifted onto a hydraulic cylinder 8 and assembled. By a hydraulic jack 7, the sleeve is connected to the mold 10, and by working the hydraulic cylinder 8, the molten metal 6 in the sleeve is pressed and fed by the bottom plug 2 into the cavity 11 in the mold 10 to execute the pressurized casting. A good casting product can be obtd. and the productivity is improved.
