Description
Technical field：
The present invention relates to the chiller on a kind of mould for Low Pressure Die Casting of Aluminum Wheel Hub, especially a kind of being directed to cool down
The central water-cooling device of aluminum alloy wheel hub casts mounting disc centre bore.
Background technology：
Aluminium alloy wheel hub is typically produced by the way of low pressure casting, and the mould for cast aluminium alloy gold wheel hub is main
Including upper die and lower die and side form, after described upper die and lower die and side form combination, form the casting mold cavity of aluminium alloy wheel hub to be cast.
During cast, sprue gate on lower mould for the aluminium liquid enters and die cavity is filled with.For aluminium alloy wheel hub, instantaneously cool down stronger, aluminium liquid
Solidification and crystallization is finer and close, and mechanical castings are better, and wheel hub cooling needs consecutive solidification.Described consecutive solidification refers to：
The solidification of foundry goods is to carry out from surface to center, partly first solidifies away from sprue gate, followed by partially solidified near sprue gate,
After be sprue gate itself solidification.Consecutive solidification can solidify position to the supplement first solidifying position and carrying out aluminium liquid after making, reduces aluminum
Liquid solidification when volume contraction and produce shrinkage cavity and shrinkage defect.At present for cooling down the cold of wheel hub centre bore on low pressure casting die
But device, typically adopts the center air blowing cooling by a cooling iron pipe just to mold diversion cone for the compressed air.In this spreader
The heart is emptied from rear end along the axial direction of cone, and pressure-air cooling pipe stretches into wherein.In the casting process of aluminium alloy wheel hub, pass through
Cooling tube empties interior blowing compressed air to spreader, through cone wall, hub centre hole is cooled down.
Using the cooling of above structure, have the disadvantages that：When to spreader when emptying interior blowing compressed air, on the one hand,
Compressed air is blown at first in the bottom emptied, then returns out along medial wall, so that the front end of spreader is cooled down the fastest.The pressure simultaneously returned out
Contracting air contacts uneven with medial wall, makes each several part non-uniform temperature of spreader, thus leading to the centre bore bottom of wheel hub
First cool down near sprue gate position, be unfavorable for consecutive solidification, cool down also uneven simultaneously.On the other hand, pressure-air cooling intensity
Limited, the aluminium liquid solidification of aluminium alloy wheel hub centre bore needs longer cool time, leads to compressed air consumption big,
High cost, secondly can produce loud noise during compressed air blowout, affect work on the spot environment.
Content of the invention：
The technical problem to be solved in the present invention is：One kind is provided to enable aluminum alloy to the cooling of low-pressure casting mould for wheel hub center all
Even, good cooling results, cooling medium reusable edible, noise-free environmentally-friendly type water cooling mold apparatus.
For solving above-mentioned technical problem, the present invention adopts such a environment-friendly type water cooling mold apparatus：It is cold that it includes center
But body, center refrigerating seat and spreader.Described center cooling body and center refrigerating seat are sealed by Cone fit, described shunting
Cone front end is in cone shape, is provided with the circular Cooling Holes axially extending to cone front inner wall, and described center cooling body stretches into point
Flow cone circular cooling in the hole, aluminium alloy wheel hub center in the hole is stretched in its front end of described spreader, rear end is fixedly mounted by pressing plate
Center in upper mould.
After above structure, the present invention compared with prior art, has advantages below：Because center cooling body is provided with
The multiple water outlet nozzles connecting with water inlet annular groove, cooling water flows into water inlet annular groove from water inlet pipe, and from multiple water outlet nozzles, to divide
Scattered mist-like ejection.On the one hand increase the contact area of cooling water and spreader Cooling Holes inwall, thus strengthening spreader
Intensity of cooling to aluminium alloy wheel hub centre bore aluminium liquid；Another aspect cooling water must compare all with spreader Cooling Holes contact internal walls
Even, also ratio is more uniform, so that aluminium alloy wheel hub centre bore circumferencial direction also cools down must compare to make the temperature of spreader circumferential section
More uniform.Cooling water, from the top of spreader Cooling Holes along inwall to dirty, makes spreader top faster than bottom cooling simultaneously, from
And enable aluminum alloy to hub centre hole aluminium liquid and improve aluminium liquid along away from sprue gate position near the downward consecutive solidification in sprue gate position
Crystalline quality.
As improvement, the plurality of water outlet nozzle is distributed along same even circumferential, makes cooling water and shunting tapered joint further
Touch more uniform, make the temperature of spreader circumferential section more uniform, finally enable aluminum alloy to hub centre hole and cool down more
Uniformly, cooling effect is more preferable, it is to avoid aluminium alloy wheel hub mounting disc is answered inhomogeneous cooling and caused the shrinkage defect of local.
As improvement, the quantity of the plurality of water outlet nozzle is 3, and the center cooling body using 3 nozzles makes spreader
, cooling effect highly uniform to the cooling of aluminium alloy wheel hub centre bore is very good.
As improvement, described center cooling body center is provided with center return pipe and stretches into inside distinguished and admirable cone Cooling Holes, cooling water
After nozzle sprays into spreader Cooling Holes, under the pressure of vapor acts on, flow out to return pipe connection from center return pipe
Heat-exchange apparatus and cooling water circulation recycling equipment.On the one hand eliminate the cooling water that spreader cools down in the hole residual in time,
After avoiding cooling stopping, spreader cooling is excessive, and affect next aluminum alloy wheel hub casts fills type；Another aspect cooling water
The heat energy taken out of can be with Collection utilization, and cooling water can also circulate and reuse, and greatlys save water resource and the energy.Simultaneously cold
But water is enclosed in pipeline all the time, will not produce noise.
As improvement, the center return pipe top of described center cooling body from spreader Cooling Holes bottom, apart from A be 10～
15 millimeters, make cooling water under the pressure of vapor acts on, more rapid, more fully from spreader cooling in the hole discharge.One side
Face further increases the initial temperature in next aluminium alloy wheel hub Filling Processes of Castings for the spreader；On the other hand also make discharge
Coolant water temperature improves, and improves follow-up thermal energy collecting and utilizes.
As improvement, described center refrigerating seat one end be threaded with shunt standard is connected, the other end be square, facilitate in
The connection of heart refrigerating seat and spreader and take cleaning apart.
As improvement, described center cooling body is 7～12 degree with center refrigerating seat by Cone fit taper B, makes center
Cooling body and center refrigerating seat seal relatively reliable.In expanded by heating, the Cone fit of center cooling body and center refrigerating seat
Energy self-locking obtains tightr.
As improvement, described center cooling body is provided with two ejection screws and symmetrical.When mould is safeguarded, conveniently from center
Dismounting center cooling body on refrigerating seat.
As improvement, it is airtight that cooling body water inlet annular groove in described center is provided with annular cover plate, and water inlet annular groove is with water inlet pipe even
Logical, center return pipe top is connected with return pipe.Due to being provided with this structure it is only necessary to a water inlet pipe and an outlet pipe just can
Cooling water is made to flow into from a water inlet pipe, an outlet pipe flows out, very convenient.
