Abstract

A multi-position parallel pressurized casting device for large aluminum alloy castings and method thereof are provided. The device includes a platform, a top surface of the platform is a working surface, and a bottom of the platform is provided with a holding furnace. A number of the holding furnace is two or more, and each holding furnace is connected to a liquid filling port corresponding to the working surface by a separate lift device, and the holding furnaces can achieve independent liquid level pressure control or synchronization liquid level pressure control in any combination by a lift control system; and a cover body is also provided on the working surface, the cover body and the working surface form a sealed working chamber. A vacuum-pumping system and an inert gas replacement system for the working chamber and/or the holding furnace are further provided.
