Description
Technical field:
The present invention relates to a kind of cooling devices on Low Pressure Die Casting of Aluminum Wheel Hub mould, especially a kind of for cooling
The central water-cooling device of aluminum alloy wheel hub casts mounting disc centre bore.
Background technique:
Aluminium alloy wheel hub is generally produced by the way of low pressure casting, and the mold for cast aluminium alloy gold wheel hub is main
Including upper die and lower die and side form, after the upper die and lower die and side form combination, the casting mold cavity of aluminium alloy wheel hub to be cast is formed.
Molten aluminum enters from the sprue gate in lower die and is filled to type chamber when casting.For aluminium alloy wheel hub, instantaneous cooling stronger molten aluminum
Solidification and crystallization is finer and close, and mechanical castings are better, and wheel hub cooling requirement consecutive solidification.The consecutive solidification refers to:
The solidification of casting is carried out from surface to center, is first solidified far from sprue gate part, followed by partially solidified close to sprue gate, most
After be that sprue gate itself solidifies.Solidification position carries out the supplement of molten aluminum to first solidification position after consecutive solidification can make, and reduces aluminium
Liquid solidify when volume contraction and generate shrinkage cavity and shrinkage defect.At present, for cooling down wheel hub centre bore on low pressure casting die
Center air blowing cooling of the compressed air by a cooling iron pipe face mold diversion cone is usually used in cooling device.The shunting
Axial direction of the cone center from rear end along cone is emptied, and compressed air cooling tube protrudes into wherein.In the casting process of aluminium alloy wheel hub,
Interior blowing compressed air is emptied to spreader by cooling tube, wall is bored and hub centre hole is cooled down.
It cools down, is had the disadvantages that when to spreader when emptying interior blowing compressed air using the above structure, on the one hand,
Compressed air is blown at first to be returned out along inner sidewall again in the bottom emptied, and makes the cooling pressure that is most fast, while returning out in the front end of spreader
Contracting air contacts each section non-uniform temperature for unevenly making spreader with inner sidewall, so as to cause the centre bore bottom of wheel hub
It is first cooled down close to sprue gate position, is unfavorable for consecutive solidification, while cooling is also uneven；On the other hand, compressed air intensity of cooling
It is limited, the molten aluminum of aluminium alloy wheel hub centre bore is solidified, longer cooling time is needed, causes compressed air consumption big,
It is at high cost, loud noise secondly can be generated when compressed air blowout, influences work on the spot environment.
Summary of the invention:
The technical problem to be solved by the present invention is providing one kind enables aluminum alloy to the cooling of low-pressure casting mould for wheel hub center
Even, good cooling results, cooling medium be can be recycled, noise-free environmentally-friendly type water cooling mold apparatus.
In order to solve the above technical problems, the present invention uses such a environment-friendly type water cooling mold apparatus: it includes that center is cold
But body, center refrigerating seat and spreader, the center cooling body and center refrigerating seat are sealed by Cone fit, the shunting
Boring front end is in cone shape, and equipped with the round cooling hole for axially extending to cone front inner wall, the center cooling body is protruded into point
In flow cone circle cooling hole, its front end of the spreader is protruded into aluminium alloy wheel hub centre bore, rear end is fixedly mounted by pressing plate
In the center of upper mold.
After using the above structure, compared with prior art, the present invention having the advantage that since center cooling body is equipped with
With multiple water outlet nozzles for be connected to of water inlet annular groove, cooling water flows into water inlet annular groove from water inlet pipe, but from multiple water outlet nozzles, to divide
On the one hand scattered mist-like ejection increases the contact area of cooling water Yu spreader cooling hole inner wall, close spreader to aluminium
The intensity of cooling of golden hub centre hole molten aluminum increases, another aspect cooling water and spreader cooling hole inner wall contact compared with
It is even, keep the temperature of spreader circumferential section also relatively uniform, so that it is also so cooling that compare to enable aluminum alloy to hub centre hole circumferencial direction
It is more uniform, at the same cooling water from the top of spreader cooling hole along inner wall to flowing down, keep spreader top faster than lower part, from
And it enables aluminum alloy to hub centre hole molten aluminum and, to close to the downward consecutive solidification in sprue gate position, improves molten aluminum along far from sprue gate position
Crystalline quality.
As an improvement, the multiple water outlet nozzle is distributed along same even circumferential, further makes cooling water and shunt tapered joint
It touches more uniform, keeps the temperature of spreader circumferential section more uniform, it is more cooling finally to enable aluminum alloy to hub centre hole
Uniformly, cooling effect is more preferable, avoids aluminium alloy wheel hub mounting disc and answers inhomogeneous cooling and cause local shrinkage defect.
As an improvement, the quantity of the multiple water outlet nozzle is 3, the center cooling body using 3 nozzles makes spreader
It is highly uniform to the cooling of aluminium alloy wheel hub centre bore, cooling effect is very good.
It is protruded into inside distinguished and admirable cone cooling hole as an improvement, center cooling body center is equipped with center return pipe, cooling water
After nozzle penetrating spreader cooling hole, from center, return pipe flows out to the heat exchange of return pipe connection under the pressure of vapor
On the one hand equipment and cooling water cycling and reutilization equipment eliminate remaining cooling water in spreader cooling hole in time, avoid
Spreader cooling is excessive after cooling stopping, influencing the type that fills of next aluminum alloy wheel hub casts, another aspect cooling water is taken out of
Thermal energy can also be recycled and be reused with Collection utilization, cooling water, water resource and the energy be greatly saved, while cooling water begins
It is enclosed in pipeline eventually, noise will not be generated.
As an improvement, the center return pipe top of the center cooling body is from spreader cooling hole bottom, distance A is 10~
15 millimeters, makes cooling water under the effect of the pressure of vapor, more rapidly and be adequately discharged out of spreader cooling hole, a side
Face further improves initial temperature of the spreader in next aluminium alloy wheel hub Filling Processes of Castings, on the other hand also makes discharge
Coolant water temperature improves, and improves subsequent thermal energy collecting and utilizes.
It is connect as an improvement, screw thread is arranged in center refrigerating seat one end with standard is shunted, the other end is set as square, makes
Center refrigerating seat facilitates the connection with spreader and dismantles cleaning.
As an improvement, the center cooling body and center refrigerating seat are 7~12 degree by Cone fit taper B, make center
Cooling body seals relatively reliable, the Cone fit energy of center cooling body and center refrigerating seat in expanded by heating with center refrigerating seat
It is closerly self-locking.
As an improvement, the center cooling body set there are two ejection screw it is symmetrical, it is cold from center when safeguarding mold
But it is more convenient that center cooling body is dismantled on seat.
As an improvement, the center cooling body water inlet annular groove is equipped with, annular cover plate is closed, and water inlet annular groove and water inlet pipe connect
Logical, center return pipe top is connected to return pipe.Due to being equipped with the structure, it is only necessary to which a water inlet pipe and an outlet pipe just can
Flow into cooling water from a water inlet pipe, an outlet pipe outflow, it is very convenient.
