Abstract

The invention relates to a five-spoke barrel casting mold. The five-spoke barrel casting mold comprises an upper box sand mold, a lower box sand mold, a casting cavity, a mud core and a chiller, wherein the upper box sand mold and the lower box sand mold are oppositely arranged, the casting cavity is positioned in a lower box, the mud core is arranged in the lower box, and the periphery of the mudcore is connected with the upper box sand mold, the lower box sand mold to form the casting cavity of a hub; a straight runner is arranged in the upper box sand mold, the straight runner communicateswith the inner cavity of the mud core, the inner cavity of the mud core is a riser-shaped cavity, a riser neck is arranged below the riser-shaped cavity, and the riser neck communicates with the casting cavity; and the chiller comprises an inner chiller and an outer chiller which are arranged up and down, and the inner chiller is arranged in a boss part of the casting cavity. According to the five-spoke barrel casting mold, the defect of shrinkage porosity of the heat joint of the casting is overcome, the cost is saved, the labor intensity of the modeling is reduced, and meanwhile, the quality of the casting is improved.

Description

technical field [0001] The invention relates to the technical field of casting of auto parts, in particular to a five-spoke wheel hub casting mold and a five-spoke wheel hub manufacturing method. Background technique [0002] With the development of the automobile industry, trailers and semi-trailers have become important transport vehicles. Therefore, people have put forward higher requirements for the performance of automobiles such as light weight and safety. Among them, the wheel hub is one of the important parts of the car, and the optimization of the performance of the wheel hub plays an important role in the optimization of the performance of the car. [0003] Such as figure 1 As shown, the existing five-spoke hub product is a ductile iron auto parts. The five-spoke hub includes a hollow wheel portion 10, five spokes 11 are evenly distributed on the outer side of the wheel portion 10, and the middle of the five spokes 11 is a cavity. structure, and the outer end of ...
