Description
Technical field
This utility model is related to a kind of aluminum alloy thin chi fin die casting structure.
Background technology
With the development of mechanics of communication, the volume of transmitted data of modern communication base station is increasing, and on base station, circuit board sends out
Heat is also more and more.The operation steady in a long-term in order to ensure base station, the radiating of circuit board just seem most important.It is existing common
Base station fin length of blade be 400mm, be highly 55mm, quantity be 30, the small end thickness 2mm of blade, withdrawing pattern are oblique
1 ° of degree.Such base station housing fin heat radiation energy reaches design requirement, but the weight of whole base station is also relatively large.
In order to meet lighter, thinner, portable lightweight requirements, and the radiating effect demand of fin is protected
Card.Therefore, it can consider to carry out loss of weight on a heat sink.In the case where cooling surface area is not changed, reduce the wall of fin
The small end wall thickness of fin is reduced to 1.2mm meeting this requirement by thickness, and pattern draft is reduced to 0.5 °.Such fin
Weight saving nearly 40%.But with thinning, the difficulty increase of press casting procedure middle period sheetmolding of fin, depanning difficulty
Increase.
The content of the invention
For above-mentioned weak point of the prior art, this utility model aims to provide a kind of aluminum alloy thin chi fin pressure
Casting structure, its design science rationally, under constant mold temperature adopt vacuum die casting process, it is to avoid cold shut, filling occur not
The phenomenon such as good, improves die cast efficiency and finished product rate, aluminum alloy thin chi fin is accomplished lighter, thinner, is met
The light-weight design of base station is required.
To achieve these goals, the technical solution of the utility model：A kind of aluminum alloy thin chi fin die casting structure, its
The upper mould and the lower mould being engaged with mould on this of composition die casting are included, and die cavity are provided between mould and lower mould on this,
The sealing strip of ring-type is provided between the upper mould and lower mould, the die cavity is located in the circulus of the sealing strip, described
Die casting is externally provided with can be to the vacuum extractor of evacuation in the die cavity；Interior circulation is provided with the upper mould and lower mould high
The heating tube of warm oil, the heating tube are uniformly distributed in the upper mould and lower mould；There are several in the die cavity and cast aluminium is treated
The die casting chamber unit that the thin chi fin of alloy matches.
Further, several die casting chamber units are respectively provided with same sprue gate, and the sprue gate waits to cast positioned at described
One end of aluminum alloy thin chi fin fin root, it is described treat the thin chi fin apex of the wing place die casting chamber unit of cast aluminium alloy it is unilateral or
Bilateral is respectively provided with flat thimble.
Further, the surface roughness requirements in the die cavity are Ra0.4.
Further, the heating tube is external on an oil temperature machine, has thermostatically-controlled equipment on the oil temperature machine.
The beneficial effects of the utility model：Design science is reasonable, by arranging evacuation, heated at constant temperature in die casting
Etc. technology characteristics, vacuum die casting process is adopted under constant mold temperature, it is to avoid cold shut occurs, the phenomenon such as bad is filled, carries
Aluminum alloy thin chi fin is accomplished lighter, thinner, meets the light weight to base station by high die cast efficiency and finished product rate
Change design requirement.
Description of the drawings
Fig. 1 is simplified schematic diagram of the present utility model.
Specific embodiment
This utility model is further described with reference to specific embodiment and accompanying drawing.
A kind of aluminum alloy thin chi fin die casting structure as described in Figure 1, its include the upper mould of composition die casting and with
The lower mould that mould is engaged on this, is provided with die cavity 10 between mould and lower mould on this, is provided with ring-type on this between mould and lower mould
Sealing strip 11, die cavity 10 in the circulus of the sealing strip 11, die casting be externally provided with can to die cavity 10 in take out true
Empty vacuum extractor 12；The heating tube 13 of interior circulation high temperature oil is provided with upper mould and lower mould, the heating tube 13 is uniformly distributed
In Yu Shangmo and lower mould；There is in die cavity 10 several and the die casting chamber unit for treating that the thin chi fin of cast aluminium alloy matches.
As aluminum alloy thin chi fin height is high, wall thickness is thin, traditional die casting structure when aluminum water is poured into a mould, aluminum alloy thin chi
The blade position aluminum water flow velocity of fin is than comparatively fast, after reaching the aluminum alloy thin chi fin apex of the wing position, aluminum current direction changes
Become, fill to fin root, by the channel blockage of inner chamber aerofluxuss, cause the air at apex of the wing end be effectively discharged out, make in apex of the wing portion
Into rolling, so as to form the defects such as cold shut, pore.This utility model can effectively improve aluminium alloy by the way of evacuation
The exhaust gas conditions of the thin chi fin apex of the wing, solve the formation problems of whole radiator shutter.In this example, each die casting chamber unit correspondence
One treats the thin chi fin of cast aluminium alloy.
Heating tube is heated using high temperature oil, and the heating tube 13 is external on an oil temperature machine, has constant temperature control on the oil temperature machine
Device processed.Whole die casting is heated using heating tube, and cause temperature constant, it is ensured that a higher mould temperature.
As aluminum alloy flake fin height is higher, draft angle is less, in order to ensure the smooth depanning of die-cast product,
Several die casting chamber units are respectively provided with same sprue gate, and the sprue gate is located at and treats the one of the thin chi fin fin root of cast aluminium alloy
End, is treating that the thin chi fin apex of the wing place die casting chamber unit unilateral or bilateral of cast aluminium alloy is respectively provided with flat thimble 14.In addition, by mould
Surface roughness requirements in chamber 10 are Ra0.4, are further ensured that the smooth depanning of die-cast product.
During use, oil temperature machine is connected first, mold temperature is improved, such as make mold temperature reach more than 180 degrees Celsius
Start die trial die casting.After mould temperature reaches, matched moulds is carried out, evacuation is closed vacuum valve after completing, starts die casting.
Above the technical scheme provided by this utility model embodiment is described in detail, it is used herein specifically
Individual example is set forth to the principle and embodiment of this utility model embodiment, and the explanation of above example is only applicable to side
Assistant solves the principle of this utility model embodiment；Simultaneously for one of ordinary skill in the art, implement according to this utility model
Example, will change in specific embodiment and range of application, and in sum, this specification content should not be construed as
To restriction of the present utility model.
