Cooling structure for a large area of a spoke of a wheel hub
By fixing cooling blocks at the bottom module of the wheel hub and forming heat-conducting protrusions with different cross-sectional areas, the shrinkage problem caused by uneven cooling during the wheel hub casting process was solved, achieving uniform cooling and high-quality forming over a large area of the wheel spokes.

Abstract
The utility model discloses a cooling structure of spoke large area place of wheel hub, including wheel hub bottom module, the bottom surface fixed cooling block of wheel hub bottom module part in the forming spoke large area place, and the inside forming cooling channel of cooling block, the bottom surface forming a plurality of heat conduction convex post of wheel hub bottom module part in the forming spoke large area place, and the bottom end surface of heat conduction convex post is pressed on the top surface of cooling block. It fixes cooling block through the bottom surface of wheel hub bottom module part in the forming spoke large area place, and it forms the heat conduction convex post of different cross -section area according to the distance of cooling channel's distance's near and far and the different forming thickness of spoke, so that its bottom surface is pressed on the top surface of cooling block, realizes the cooling of guide, thereby guarantees the cooling solidification speed even of spoke's large area place part, guarantees the forming quality, and basically does not have the problem such as shrinkage.
