Problems solved by technology
The disadvantages are: in order to meet the requirements of internal quality, the mold temperature is high, the mold life is low, the product appearance guarantee ability is poor, common mold corrosion and aluminum sticking problems
At the same time, the mechanical properties of the product are low, especially the elongation rate is low, and the yield strength and tensile strength are also slightly low
The cooling effect is slow, and the purpose of strong cooling and grain refinement cannot be achieved
Compressed air costs more

Description
technical field [0001] The invention relates to a cooling system, in particular to a water cooling device for a casting aluminum alloy wheel hub mold. Background technique [0002] There are generally two cooling methods for the molds of the existing low-pressure casting molding technology: compressed air cooling and compressed air and local water cooling. The disadvantages are: in order to meet the requirements of internal quality, the mold temperature is high, the mold life is low, the product appearance guarantee ability is poor, and the mold corrosion and aluminum sticking problems are common. At the same time, the mechanical properties of the product are low, especially the elongation, and the yield strength and tensile strength are also slightly low. The cooling effect is slow, and the purpose of strong cooling and grain refinement cannot be achieved. Compressed air is expensive. Contents of the invention [0003] The technical problem to be solved by the present ...
