Hot chamber casting machine for aluminum alloy and hot chamber casting method using aluminum alloy as metal material

摘要

PROBLEM TO BE SOLVED: To provide a hot chamber casting machine for aluminum alloy which has a high casting speed and does not cause a problem of melting of an internal mechanism even when a molten aluminum alloy is used. A melt injection main cylinder 120 made of ceramic is provided in a melting furnace 110. A valve body 150 is provided in a position lower than the injection path 130 in the molten metal injection main cylinder 120, and a gas pressure of a predetermined pressure is applied to the internal space 123 of the molten metal injection main cylinder 120 by the pressurizing unit 160. Controlled removal. When the pressurizing unit 160 applies a gas pressure, the valve body 150 works in a closing direction, and the molten metal inside the molten metal injection main cylinder 120 is die-cast from the injection path 130 to the mold 200. When the pressurizing unit 160 removes the gas pressure, the valve element 150 is opened, and a required amount of molten metal is supplied to the internal space 123 for the next die casting.
