Casting cooling system, casting mold and casting method for aluminum hubs

Abstract

The invention relates to the field of automobile part casting and discloses a casting cooling system for aluminum hubs. The casting cooling system comprises an upper mold cooling subsystem and a bottom mold cooling subsystem, wherein the bottom mold cooling subsystem comprises a bottom mold feed head air duct, a bottom mold front-hung water-cooling disc and a bottom mold middle-circle water-cooling disc; and the bottom mold front-hung water-cooling disc and the bottom mold middle-circle water-cooling disc are located in positions, which are close to the outer end and the air duct, of the lower part of a bottom mold respectively. The invention further discloses a low-pressure mold for the aluminum hubs. The mold comprises the casting cooling system for the hubs. The invention further discloses a casting method for the aluminum hubs. The casting cooling system, the mold and the casting method have the benefits as follows: a traditional air-cooling system is improved into an air and water mixed cooling system by the aid of the upper mold cooling subsystem, the bottom mold cooling subsystem and a side mold cooling subsystem; and meanwhile, the cooling efficiency and the cooling quality are improved, the production time is shortened, and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of casting of automobile parts, in particular to an aluminum hub casting cooling system, a casting mold and a casting method. Background technique [0002] The cooling system of the existing aluminum wheel hub casting mold is mostly air-cooled, such as figure 1 As shown, it mainly includes the upper mold slope air cooling 41 on the upper mold, the upper mold PCD air cooling 42, the upper mold PCD internal air cooling 43, the upper mold splitter cone air cooling 44, and the lower mold outer ring on the lower mold Air cooling 51, bottom mold outer ring air cooling 51, bottom mold inner ring air cooling 52, bottom mold riser air cooling 53, the cooling efficiency is low, reducing production efficiency and product quality, while maintaining pressure when producing aluminum wheels The time is longer, prolonging the production cycle of aluminum wheels.
