Description

Technical Field

[0001] The invention belongs to the technical field of aluminum alloy wheel hub processing molds, and particularly relates to a lower mold with an adjustable water cooling structure and an adjustment method thereof. Background Art

[0002] Aluminum alloy automobile wheels have gradually replaced steel wheels due to their light weight, high thermal conductivity, good formability and beautiful appearance, and low-pressure casting is the main production method of aluminum alloy wheels today. Low-pressure casting is to pour molten aluminum into the mold through equipment under pressure, and the entire solidification process of the molten aluminum is under a certain pressure.

[0003] At present, most processes in wheel hub casting use water cooling or a combination of water cooling and air cooling. The water cooling method is to set a water cooling pipe inside the mold for cooling. After long-term processing, the water cooling pipe is prone to heat deformation or loss, making the distance from each position of the water cooling pipe to the mold wall different, resulting in uneven heating of the wheel hub during molding, making it impossible to ensure the molding quality. At this time, the water cooling pipe needs to be replaced.

[0004] At the same time, in the prior art, due to the different shapes of the cast products, the wall thickness of the casting area is different, and it is necessary to configure annular grooves of different sizes to install water cooling pipes of different diameters to ensure the cooling effect.
