Description

Technical Field

[0001] The utility model belongs to the field of low-pressure casting mold design, in particular to an improved water-cooled side mold of an aluminum alloy wheel hub mold. Background Art

[0002] In order to improve the casting quality, production efficiency and energy saving of the wheel hub, the cooling method of the casting mold is gradually changing from air cooling to water cooling. The compressed air used in the air cooling method cannot be recycled, while the cooling water used in the water cooling method can be directly recycled and reused, thereby achieving the purpose of energy saving. The traditional mold water-cooled side mold structure is usually composed of a water-cooled insert. This design can effectively reduce the temperature of the mold and meet the cooling requirements during the casting process. However, at the position of the corresponding hot node, the cooling process is not easy to control, which may cause casting defects at the rim position, such as insufficient pouring, looseness and other defects. If two upper and lower water-cooled inserts are set, each water-cooled insert will have two more joints, and the equipment needs to be modified to meet the water cooling requirements of the mold. These problems not only affect the quality of the wheel hub, but may also increase production costs and reduce production efficiency. Therefore, how to improve the cooling system of the low-pressure casting mold of the aluminum alloy wheel hub and improve the casting quality and casting efficiency is a problem that needs to be solved urgently.

Then, the bolts pass through the bolt stepped holes on the side mold body and the threaded holes 1 and 2 of the upper insert respectively to fix the insert assembly on the side mold body. Then, the sealing ring and the threaded joint are connected to the threaded stepped water outlet hole of the upper insert and the threaded stepped water inlet hole of the lower insert respectively. Finally, the connecting pipe is connected to the threaded joint.

[0006] Preferably, the upper insert groove and the lower insert groove of the side mold body are clearance-matched with the upper insert and the lower insert, and the clearance range is 0.05-0.2mm.

[0007] Preferably, the bolt stepped holes of the side mold body correspond to threaded hole 1 of the upper insert and threaded hole 2 of the lower insert respectively.

[0008] Preferably, the locating pin holes of the side mold body correspond to the locating pin hole 1 of the upper insert and the locating pin hole 2 of the lower insert respectively.
