[0002] A casting mold is a material that is made of other easily formed materials in advance in order to obtain the structural shape of a part. The mold is then placed in a sand mold, forming a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed. The casting mold is an important part of the casting process.

[0003] The existing aluminum alloy casting mold is made by first heating the aluminum alloy ingot into a liquid state inside a large heating barrel. At this time, the heating barrel can be tilted to inject the liquid aluminum alloy into the nearly sealed transmission box along the injection port. At this time, the filling port is sealed by electronic control, and then inert gas can be injected into the transmission box through a pressure bottle, thereby squeezing the liquid aluminum alloy inside the transmission box and injecting the liquid aluminum alloy into the mold to form it. After the aluminum alloy is formed, the operator knocks on the surface of the aluminum alloy part to demold the part. Utility Model Content
