Abstract
The utility model provides an aluminum alloy wheel hub side die provided with radiating fins, comprising a side die body, the side die body is provided with radiating fins, the radiating fins are disposed at a region with highest heat during casting of the side die, increasing heat transmission capability of the die, and making the side die balance the die temperature of each part of a cast via natural heat radiation, and shorten the casting forming time difference of parts of the aluminum alloy wheel hub cast.
Description
Technical field
The utility model belongs to the die casting field, is specifically related to a kind of aluminum alloy wheel hub flange mould with fin.
Background technology
In the casting aluminium alloy wheel hub process, the quality of wheel hub depends on the quality of wheel hub blank foundry goods.Low Pressure Casting Technology has been widely used as making the method for aluminum alloy hub blank foundry goods because of himself advantage.Casting mould is the key processing equipment of wheel hub moulding.Casting mould is comprised of upper die and lower die, Bian Mo and mould bases, and the temperature of mould is the key factor that affects casting quality.
Considered in the past machinability, the wall thickness of the limit mould in the mould molding system is designed to uniform thickness, thickness error generally is no more than 10mm.But the wall thickness of hub cast is inhomogeneous, and like this with regard to so that the thinner position of when casting casting thickness has better flowability because of metal heat preservation, moulding is very fast, but the thicker position of casting thickness does not cause setting rate slow because dispel the heat.Foundry goods each several part cooling velocity is different during liquid metal filling, process of setting namely produces stress, cause each position volume contraction asynchronous, form pore and shrinkage cavity, follow-up when carrying out surface treatment, hole can be intake, spray again and when electroplating rear baking, when gases are heated, they expand in the hole, causes the hub cast surface blistering, do not reach the surface quality requirement, and can't be by gas leakage and antifatigue test.Because the each several part wall unevenness of wheel hub is even, setting time presents gradient difference in the forming process.So the generation of avoiding shrinkage cavity and pore need to improve the type of cooling of casting mould.
At present, air-cooled and water-cooled dual mode is adopted in the cooling of die casting usually.Air-cooled cooling velocity is slow, and production efficiency is low, is applicable to the little mould of heat dissipation capacity.And the mould of employing water-cooled, amount of cooling water and cooling velocity are large, are difficult to accurately control cooling position, and need to offer cooling water channel at mould, so the structure of mould is relatively complicated.Above-mentioned dual mode all needs the equipment of external supply cooling medium, and energy resource consumption is large.
Summary of the invention
When aluminium alloy wheel hub carried out casting and pouring, the heat that the Al-alloy metal liquid at thin-walled place has was less, and cooling velocity is fast, and foundry goods heavy wall place heat is large and the mould temperature is higher, and cooling velocity is slow.Therefore the utility model by the shape of foundry goods, is adjusted mold temperature and is made its casting process medium casting each several part mould temperature even when designing mould.
Existing limit mode structure larger cooling velocity gradient in the time of can't eliminating the foundry goods moulding.Design object of the present utility model is time difference of making foundry goods Hou Chu and Bao Chu dwindle cooling, solidify of the mode by external equipment not, to reduce energy consumption, simplifies mould structure, enhances productivity.For achieving the above object, the utility model provides a kind of brand-new limit mould design, and utilization is carried out natural heat dissipation at the fin 1 that the limit mould corresponds to the setting of casting section thickness thickness, effectively controls the process of setting of foundry goods, realizes the consecutive solidification of foundry goods.
The utility model wheel rim that corresponding hub cast is thicker on the mould of limit and spoke handing-over position increase fin 1, utilize the cast iron of fin 1 to absorb and conduct the casting heat to air, improve the flowability at thicker position, accelerate its cooling, elimination is because of the gradient type refrigerating mode that the foundry goods became uneven forms, and the time difference that makes the thicker position of foundry goods and thinner position will cool off, solidify shortened to for 3 to 8 seconds.
Beneficial effect:
The utility model is verified by production practices, and internal soundness and the surface quality of die casting have improved in the hub cast dense structure that produces, and wearability and the corrosion resistance of cast(ing) surface strengthen by testing not only, and the hardness of whole foundry goods also is improved.Need not increase in addition water-cooled or air cooling equipment, reduce the use amount of the energy, reduce production cost.Improved production efficiency, cooling, setting time is poor shortened to for 3 to 8 seconds.Stablize the dimensional accuracy of die casting, improved the mold use life-span.
Description of drawings
Accompanying drawing 1 is the front view of limit mould fin,
Accompanying drawing 2 is touched the top view of fin for the limit.
Among the figure: 1 fin.
The specific embodiment
A kind of aluminum alloy wheel hub flange mould with fin 1 of the utility model, the wheel rim that temperature is the highest, heat is the most concentrated in the die cavity during maximum corresponding to the hub cast wall thickness on the mould of limit, casting increases fin 1 with the spoke handover region, utilizes fin 1 to absorb the casting heat and conducts in the air outside the mould.
A kind of processing method with aluminum alloy wheel hub flange mould of fin 1 of the utility model is, produce first the model of aluminum alloy wheel hub casts, then according to the desert of wheel hub modelling limit mould, set up simultaneously heat radiating fin structure, pour into a mould at last, fin 1 has a style of one's own with the limit mould, namely forms the limit mould with fin 1.
Limit of the present utility model mode structure is simple, the casting of carrying out wheel hub adds man-hour, and the molten metal that has strengthened the large position of the casting section thickness property that flows is accelerated its cooling velocity, the balanced mold temperature at foundry goods different-thickness position, thus shortened with cooling, the molding time of thin-walled place foundry goods poor.
