Abstract
The invention provides a method for cooling a die of a low-pressure cast aluminum alloy hub in a water-mist mode. The method comprises the following steps that atomizing nozzles are arranged on the portions, correspondingly needing cooling, of the die of the low-pressure cast aluminum alloy hub, wherein switches of the atomizing nozzles are controlled by an electromagnetic valve; the pure water with specific conductance smaller than or equal to 20 microsecond/cm is produced through a reverse osmosis type water purification machine, and the obtained pure water is supplied to the atomizing nozzles by a variable frequency constant pressure water supplying device through a pipeline; after the casting process is completed, the atomizing nozzles are controlled to be opened through the electromagnetic valve, and the pure water mist is sprayed to the corresponding portions, needing cooling, of the die to conduct cooling; after the cooling process is completed, the accumulated water below the die is drained. The method for cooling the die of the low-pressure cast aluminum alloy hub in the water-mist mode is low in cost, large in cooling strength, moderate in cooling speed and easy to control, the production cycle of the hub is shortened by more than 15%, and the ductility of a spoke is also improved.
Description
Technical field
The present invention relates to a kind of water smoke cooling means of mould of low pressure casting aluminum alloy wheel hub, belong to wheel hub and make the field.
Background technology
At present, aluminium alloy wheel hub is widely used at passenger car, and about 90% aluminium alloy wheel hub is produced with low-pressure casting process.
In the production process of low pressure casting aluminum alloy wheel hub, the cooling of casting mould not only influences the inherent quality of foundry goods, and has influence on production efficiency and manufacturing cost.
The method of present air-cooled technology-namely adopt compressed air to cool off is very ripe at the aluminium alloy wheel hub casting industry, also is domestic the technology that generally adopts.But this technology has following weak point: the one, and the cost height is produced a large amount of electric energy of compressed air consumption, and this also is the project of each aluminium alloy wheel hub manufacturing company consumed power maximum; The 2nd, intensity of cooling is little, and is very slow because compressed air is taken away the speed of heat, therefore, can not satisfy the local needs of cooling fast in the aluminium alloy wheel hub casting process, also limited the further raising of production efficiency.
In addition, the direct water-cooling mode is a kind of method that improves cooling velocity, but the cooling velocity of water-cooled is too fast, is difficult to obtain control, and is also bigger to the infringement of mould.So water-cooling process is not applied in aluminium alloy wheel hub production.
Adopt the method for recirculated water cooling also to obtain certain application in the industry in low pressure casting aluminum alloy wheel hub industry in recent years; It is characterized in that remedying so as to the increase intensity of cooling at the corresponding site design cycle aquaporin of mould the deficiency of air cooling way, but owing to adopt the mould structure of recirculated water cooling method and the complexity of manufacturing to improve greatly, and because structural limitations, a lot of positions can not be used, so this cooling means is not widely used equally.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defective, and a kind of water smoke cooling means of mould of low pressure casting aluminum alloy wheel hub is provided, and cost is low, and intensity of cooling is big, cooling velocity moderate and be easy to control.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
A kind of water smoke cooling means of mould of low pressure casting aluminum alloy wheel hub may further comprise the steps:
A. arrange atomizer at the position in requisition for cooling of the mould of low pressure casting aluminum alloy wheel hub, the switch of atomizer is by solenoid control;
B. make the pure water of electrical conductivity≤20 μ S/cm with the reverse osmosis type water purification machine, and use the constant pressure water supply device that the gained pure water is supplied to atomizer by pipeline;
C. after foundry work is finished, open by the solenoid control atomizer, the position ejection pure water water smoke in requisition for cooling of mould is cooled off;
D. after cooling is finished, discharge the ponding of mould bottom.
Further, atomizer is adjustable nozzles.
Further, be provided with backing plate below the mould.
Further, be provided with drip tray between mould and the backing plate.
The water smoke cooling means of the mould of a kind of low pressure casting aluminum alloy wheel hub of the present invention, cost is low, and intensity of cooling is big, and cooling velocity is moderate and be easy to control, and the production cycle with wheel hub has shortened more than 15% simultaneously, and the percentage elongation of spoke also is improved.
