Problems solved by technology

However, since the hub has no central hub and the filling of the spokes, for the rim of the three-piece hub, it is obviously impossible to fundamentally install the cooling ring at the junction of the upper mold, the lower mold, and the side mold. Solve the shrinkage problem

Abstract

The invention discloses a rim gating system, wherein a lower mould, an upper mould and a side mould define a rim gating cavity, a sprue is formed in the middle of the right side of the side mould, risers are formed between the upper part of the side mould and the upper die, a blind riser is formed in the middle of the left side of the side mould, a water-cooling structure is arranged between the lower side of the bottom of the upper mould and the lower die, and an air-cooling structure is arranged at a position which is at the upper side of the bottom of the upper die and above the blind riser of the upper part of the side mould. The air-cooling structure comprises a first air-cooling structure, a second air-cooling structure and a third air-cooling structure, wherein a wind board is arranged between the first air-cooling structure and the second air-cooling structure. The rim gating system adopts the gating system, the cooling system and the blind riser system which are reasonable integrally, so the shrinkage porosity problem of a thin-wall casting during the production process is solved thoroughly.

Description

technical field [0001] The invention relates to wheel rim casting technology. Background technique [0002] Thin-walled castings are prone to shrinkage during the production process, especially for three-piece hubs. The central hub and rim are processed separately. Since the rim is relatively thin-walled casting, there is no central hub and spokes. Therefore, shrinkage and porosity are prone to occur during the pouring production process. Chinese Utility Model Patent (Application No. 201020120558.0, published on December 12, 2010) discloses a low-pressure casting hub mold, including an upper mold, a lower mold and a side mold. After the upper mold, lower mold and side mold are combined Form the casting cavity of the hub to be cast, the lower mold is provided with a sprue, the area formed by the junction of the upper mold, the lower mold, and the side mold is the hot node of the cast hub, and the inner side of the side mold A cooling ring is inlaid at the hot node, and a co...
