Pressure casting machine

A pressure casting machine comprising:

• a vacuum chamber comprising:
• 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;
• and
• a pressure casting mechanism comprising:
• a first core received in the processing section;
• a second core received in the processing section, and coupled to the bottom wall and opposite to the first core;
• a plurality of pushing members received in the processing section and coupled to the top wall, and positioned between the top wall and the first core;
• and
• a first driver positioned adjacent to the top wall and coupled to the first core, configured to move the first core to engage with the second core.

A pressure casting machine configured to mold a molten material into a workpiece, the pressure casting machine comprising:

• a processing section:
• a first gate configured to seal the processing section;
• a first vacuum pump coupled to the processing section;
• a first driver positioned adjacent a top of the processing section;
• a first core located in the processing section and coupled to the first driver;
• a second core located in the processing section, coupled to a bottom of the processing section, and opposite to the first core;
• and
• at least one pushing member between the top and the first core;
• wherein the first driver is configured to move the first core toward and into engagement with the second core to define a mold, and to move the first core away from the second core and into engagement with the pushing members, whereby the pushing members insert through the first core and dislodge the workpiece out of the first core.
