Technical Field

[0001] The utility model relates to the technical field of low-pressure casting of aluminum alloys, in particular to a composite pouring riser for a metal mold for low-pressure casting of aluminum alloys. Background Art

[0002] Low-pressure aluminum alloy casting is a casting method that allows liquid aluminum alloy to complete the filling of the aluminum casting mold cavity and solidification process under relatively low pressure, thereby obtaining high-quality and high-precision castings.

[0003] A pouring riser is an inevitable "excess" portion of metal produced during the casting process. It consists of two parts: the sprue, which is the entrance for molten metal from the gating system into the casting cavity, and the riser, a supplementary component specifically designed to compensate for shrinkage. Their primary function is to ensure casting quality during the casting process. However, traditional pouring risers are open at the top during static operation, which can easily allow foreign matter to enter the device, affecting stable casting. Utility Model Content
