Title:
TILT TYPE GRAVITY MOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/089711
Kind Code:
A1
Abstract:
A tilt type gravity molding device comprises: a mold (3) which can tilt between a fallen position and a standing position raised approximately 90 degrees from the fallen position; a pouring mold (7) in which a pouring gate (71) for guiding molten metal to the cavity (2) for forming a molded article is formed; and a bowl-like member (4) which contains the molten metal and pours the molten metal into the pouring gate (71) as the mold (3) tilts. In order to eliminate the need for a feeder head and for a reduction in the tilt speed and to enable the molten metal within the mold to be appropriately pressurized by gas, the tilt type gravity molding device also comprises: a blocking means (8) which is provided between the pouring gate (71) and the cavity (2) and which can open and close the pouring gate (71); a gas opening (9) which is provided at the upper part of the mold (3) in the standing position, prevents the molten metal from flowing to the outside of the mold (3), and permits only gas to pass therethough; and a gas supply means (91) which can supply a high-pressure gas to the gas opening (9).
