Abstract
A pressure casting machine can be configured to mold a molten material into a workpiece. The pressure casting machine can include a vacuum chamber and a pressure casting mechanism coupled to the vacuum chamber. The vacuum chamber can include a processing section having a top wall and a bottom wall opposite to the top wall, a first gate configured to seal the processing section, and a first vacuum pump coupled to the processing section. The pressure casting mechanism can include a first driver positioned adjacent to the top wall, a first core received in the processing section and coupled to the first driver, a second core received in the processing section, and a plurality of pushing members received in the processing section. The second core can be coupled to the bottom wall and opposite to the first core. The pushing members can be coupled to the top wall.
