Title:
CASTING METHOD AND CASTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/151701
Kind Code:
A1
Abstract:
After molten metal (M) is raised close to a gate (11) of a cavity (9C) by pressurizing the interior of a holding furnace (5) with gas, the pressure in the cavity (9C) is reduced by suction, the interior of the holding surface (5) is further pressurized, and the molten metal (M) is filled into the cavity (9C). Thereafter, minimum necessary suction is performed by stopping the reduction of the pressure in the cavity (9C) after a lapse of a preset filling time, and stopping the pressurization of the interior of the holding furnace (5) with the completion of solidification of the molten metal (M), thereby simplifying a pressure reducing means (14), and achieving reduced equipment cost and manufacturing cost, and a shortened casting cycle time.
