Problems solved by technology
Although there will not be too many problems in the forming of this aluminum alloy wheel low-pressure casting mold during the casting process, due to some convex ribs on the mounting plate in the middle of the hub and the inner ring surface of the rim during the thermoforming process, Partly limited by the structure of the mold itself, it cannot be cooled well, so the mounting plate and rim after casting are more likely to be deformed, and the overall quality and performance of the wheel hub will be reduced in the subsequent process

The invention discloses a low-pressure air cooling hub mold. The low-pressure air cooling hub mold comprises a bottom plate, a mold body and a plurality of air cooling devices, wherein the mold body is mounted on the upper end face of the bottom plate and comprises a top mold, a bottom mold, a left edge mold and a right edge mold which are matched mutually, and a sprue gate is formed in the bottommold; and the multiple air cooling devices are distributed in the top mold, the bottom mold, the left edge mold and the right edge mold and comprise air cooling devices, air exhaust grooves and air cooling pipes, the air exhaust grooves are formed in the mold body, the air cooling pipes are mounted in the air exhaust grooves, the air cooling pipes are provided with air inlets and air outlets, theair outlets of the air cooling devices communicate with the air inlets of the air cooling pipes, and a plurality of flow-dividing holes are formed in the air cooling pipes. According to the low-pressure air cooling hub mold, elastic cushions are arranged on fixing bolts in a sleeving mode, the precision of an injection molded part is ensured, and the product quality is ensured; and through a heatpreservation device arranged at the sprue gate, it can be ensured that the sprue gate is kept at the high temperature, and injection molding liquid enters a mold cavity stably.
Description
technical field [0001] The invention relates to the technical field of mechanical casting, in particular to a low-pressure air-cooled hub mold. Background technique [0002] As one of the most important moving parts of a car, the wheel hub has high requirements on its performance, weight and service life. Wheels are generally produced by casting, and mold cooling is an important part of the production process. Aluminum alloy wheel hub low-pressure casting molds are extremely common molds in the wheel hub manufacturing industry and are also widely used. At present, the traditional aluminum alloy wheel hub low-pressure casting mold includes an upper mold and a lower mold. The upper mold is provided with a glue injection hole, and the lower mold is provided with a sprue sleeve at a position corresponding to the glue injection hole. The liquid suction pipe in the mold is provided with a liquid riser extending to the lower side of the lower mold on the liquid suction pipe. Alt...
