Abstract

To eliminate the need for a riser and for reduction in tilt speed and to enable molten metal contained in a mold to be pressurized by gas appropriately, a tilt type gravity molding device including a mold which can tilt between a fallen position and a standing position raised approximately 90 degrees from the fallen position, a pouring gate mold in which a pouring gate guiding the molten metal to a cavity of a molded article is formed, and a bowl-like member which stores the molten metal and pours the molten metal into the pouring gate in accordance with tilt of the mold includes closing means which is provided between the pouring gate and the cavity and can open and close the pouring gate, a gas inlet 9 which is provided at an upper portion of the mold at the standing position, prevents the molten metal from flowing out of the mold, and allows only gas to pass therethrough, and gas supplying means which allows high-pressure gas to be supplied to the gas inlet.
