Wheel casting apparatus and method based on multi-gating with tire bead seat

Abstract

The present application relates to the technical field of counter-gravity casting, and discloses a wheel casting forming equipment and method based on an outer bead seat and multiple sprue filling, which comprises a holding furnace, a liquid lifting pipe, a mold and a pressure system; the metal liquid is made to rise through the liquid lifting pipe and enter the mold by controlling the pressure system; the liquid lifting pipe is connected with a sprue cup at the top, the metal liquid is poured into a horizontal sprue through a pouring structure, the horizontal sprue is located at the position of the outer bead seat, surrounds the wheel for one round, and is connected with the mold cavity, the metal liquid is horizontally poured, the pouring structure comprises four pouring channels of three structures, and the included angles between the four pouring channels are all 90 degrees; the large-size aluminum alloy wheel is cast by adopting the present application, the filling is stable, the feeding distance is greatly shortened, the shrinkage cavity and shrinkage porosity and other casting defects are controlled, and the casting forming quality and mechanical properties of the large-size aluminum alloy wheel are significantly improved.
