However, in the production process, in this method of aluminum alloy casting and forming the wheel hub, the hub casting in the mold is placed horizontally, in other words, the radial plane of the hub is placed horizontally, so the mold of the hub consists of the upper mold, The lower mold and the side mold are composed. One end of the wheel hub with a web is located at the lower part of the mold, and the free end of the other end is located at the upper part of the mold, and a side riser should be set at the edge of the free end. Since the thickness of the edge is relatively thin, it is the last Cool the solidified part, therefore, the fast water cooling is easy to produce casting defects such as air bubbles and shrinkage porosity at the edge of the hub; and, in this case, the casting is easy to become oval at the free end of the rim after demolding

The invention discloses an aluminum alloy hub casting mold. The aluminum alloy hub casting mold comprises a top mold, a bottom mold and multiple side molds; the top mold, the bottom mold and the multiple side molds form a molding cavity for forming a hub; and a cooling water way is formed in the bottom mold. The aluminum alloy hub casting mold is characterized in that a guide rail is arranged at the bottom of each side mold; each side mold is connected with a slide cylinder; slide pieces are slidingly arranged at the upper ends of the side surfaces, for forming the hub, on the side molds; the slide pieces are seamlessly bonded with the side surfaces, for forming the hub, on the side molds; mounting grooves are formed in the back parts of the side molds; the positions of the mounting grooves are corresponding to the positions of the slide pieces; pushing cylinders are arranged in the mounting grooves; output shafts of the pushing cylinders are connected with the slide pieces; multiple nozzles are arranged at the bottoms of the mounting grooves; and the nozzles are connected with a spraying system.
Description
technical field [0001] The invention relates to a mold, in particular to an aluminum alloy wheel hub casting mold. Background technique [0002] At present, most wheels are made of aluminum alloy wheels. There are three manufacturing methods: gravity casting, forging and low-pressure precision casting. Among them, gravity casting is to use gravity to pour aluminum alloy solution into the mold. After forming, it can be finished by lathe treatment and grinding. Production. Because of its simple manufacturing process, no precision casting process, low cost and high production efficiency, it is adopted by most manufacturers. However, in the production process, in this method of aluminum alloy casting and forming the wheel hub, the hub casting in the mold is placed horizontally, in other words, the radial plane of the hub is placed horizontally, so the mold of the hub consists of the upper mold, The lower mold and the side mold are composed. One end of the wheel hub with a web ...
