Spoke casting mould

Abstract

The invention discloses a spoke casting mould which comprises an upper mould body connected to an upper mould mounting plate and a lower mould body connected to a lower mould mounting plate. An upper mould ring is arranged on the periphery of the upper mould body, the upper end face of the upper mould ring is fixedly connected with the upper mould mounting plate, and the lower end face formed by combining the upper mould ring and the upper mould body is matched with the upper end face of the lower mould body. According to the spoke casting mould, the upper mould ring and the upper mould body are tightly matched, the sealing face between the upper mould body and the lower mould body is reduced, the phenomena of aluminum flowing and flange generating are effectively avoided, raw materials are saved, the manufacturing cost of a spoke is reduced, the difficulty of follow-up cleaning work is reduced, and the manufacturing period of the spoke is shortened. The upper mould body is surrounded by the upper mould ring, the temperature maintaining effect is obviously improved, the time for repeatedly heating the mould is greatly shortened, energy consumption is reduced, and the manufacturing cost of the spoke is reduced.

Description

technical field [0001] The invention relates to the field of casting molds, in particular to a mold for casting wheel spokes. Background technique [0002] In the manufacturing process of the straight-through wheel hub, the rim and the spokes need to be manufactured separately, and then composited and welded to form the hub. The spokes are manufactured by casting process. The spoke casting mold in the prior art includes an upper mold, a lower mold and a middle mold. The middle mold includes several The sections are combined to form the arc-shaped modules of the ring. After the upper and lower molds are connected, the arc-shaped modules of the middle mold are respectively pressed on the outer walls of the upper and lower molds through hydraulic cylinders. When the spokes are formed, the middle molds are reset, and the upper and lower molds The mold is separated, the spokes rise with the upper mold, and the operator sends the tray to the bottom of the upper mold, and the spoke...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a spoke casting mold, which can solve the problems of the prior art that there are many sealing surfaces between the molds, aluminum running and flashing are serious, and the mold is completely opened when the mold is demoulded, and the temperature diverges quickly The problem
