Car wheels are an important part of a car. The material can be divided into aluminum alloy, steel and composite materials. Composite material mainly refers to carbon fiber, which has high price, low promotion rate and complex manufacturing process. Common household car wheel materials are steel and aluminum alloys. Aluminium alloy wheels have long been widely used in the automotive industry because of their lightweight appearance and heat dissipation characteristics. At the same time, the appearance of steel wheels is not as beautiful as aluminum alloy wheels. Aluminum alloy wheels can release more heat so they have a wide range of applications.

Aluminum alloy wheels have many characteristics unmatched by steel wheels, so aluminum alloy wheels have been widely used in cars, motorcycles and other vehicles.
Low pressure casting can achieve a high degree of mechanization and automation, which can not only improve productivity (10-15 types/h), but also reduce many human factors that are not conducive to the production process, improve the yield, and greatly reduce the labor intensity of workers. However, the quality of low-pressure castings is affected by factors such as process plan, process parameters, mold structure and manual operation, as well as their mutual influence. Unreasonable design or improper operation of any link may lead to defects in low-pressure castings.
Among them, the occurrence of aluminum alloy wheel hub cracks is an important factor affecting the production cost and production efficiency of enterprises, and wheel hub cracks are a major hidden danger to automobile safety. Therefore, it is particularly important to discuss the causes of cracks in low-pressure cast aluminum alloy wheels.
Improvement measures
Reasonable design of the lift system. Due to the long pressure holding time or the long riser pipe, the liquid in the riser tube solidifies, so that the wheel hub casting will bear a certain tension when it is ejected, resulting in cold cracking of the wheel hub.
The hydraulic system is very important to reduce the tendency of cracking. The liquid rising system refers to the channel through which the liquid metal enters the cavity from the crucible during pouring, including the liquid riser, the thermal insulation jacket and the casting pouring system. The size of these parts directly affects the distance between the liquid level in the crucible and the gate in the casting. The longer this distance is, the faster the liquid metal cools down when pouring through this distance, which is very likely to cause early condensation of the riser channel.
It should therefore be noted that:
Shorten the distance between the liquid level in the crucible and the gate in the casting. This distance involves several aspects such as equipment, technology, mold, etc., so it is necessary to comprehensively consider it, and it is appropriate to shorten this distance.
Improve the thermal insulation cover. Appropriately increase the business diameter of the thermal insulation jacket to expand the thickness of the thermal insulation layer; use materials with good thermal insulation performance as the thermal insulation jacket, such as aluminum silicate fiber felt.
Properly increase the diameter of the riser pipe. To prevent the early solidification of the riser, the diameter of the riser should be appropriately increased.
Reasonably designed hub structure When designing the hub structure, the sharp corner structure and the sudden change of the cross section should be avoided, and the rounded corner or the structure with uniform thickness should be adopted.
Appropriately increase the mold temperature without casting defects.
