Description
Technical field
The utility model is related to a kind of casting mould, specifically a kind of split of low-pressure casting die of aluminium alloy wheel
Aqueous cold plate.
Background technology
Core wheel ring flange is the key position being connected to wheel on vehicle wheel shaft, quality of each main engine plants to core wheel
Precision suffers from strict requirements, to ensure the security of vehicle traveling process.However, in aluminum-alloy wheel low-pressure casting process
In, due to the thick big modeling characteristic of core wheel, obvious casting thermal center is formed it into, has become in production and defect most easily occurs
Position.At present, it is traditional it is air-cooled be still the most frequently used type of cooling of aluminum-alloy wheel manufacturer, as shown in Figure 1.This technology
Have the disadvantage thermal capacitance very little, thermal conductivity factor is low so that the heat in core wheel set of regions can not be exported quickly, cause aluminium liquid solidification slow
Slowly, make cast-internal that the defects such as shrinkage porosite, shrinkage cavity occur.Simultaneously because degree of supercooling is low, it is thick to will also result in core wheel internal grain,
Tissue is not fine and close, causes mechanical property low.In addition, too high temperature can also make cast-internal form larger structural stress,
Cause casting deformation and scrap.The all serious smooth production that govern wheel of all these problems, affects yield rate.
The content of the invention
The utility model purpose be to provide it is a kind of effective solve low pressure casting wheel core wheel flange region shrinkage porosite, shrinkage cavity,
The aqueous cold plate of the problems such as coarse grains, casting deformation.
The technical solution of the utility model is：Improved wheel die aqueous cold plate, including central water-cooling disk, water inlet pipe, stone
Ink pad piece, alignment pin, installation bolt, outlet pipe.Cyclic structure aqueous cold plate is arranged in core wheel flange region, aqueous cold plate and backform spiral shell
Tether connect, cylinder finger setting.Water annulus is set inside aqueous cold plate, and water annulus rectangular cross-section, water annulus is close with baffle plate
Envelope, it is ensured that current circulation is water-tight；Water inlet pipe, outlet pipe are welded on water annulus, water inlet pipe, outlet pipe are distributed in 180 °, with
Farthest ensure the uniformity of cooling by water.
Inclined-plane coordinates between aqueous cold plate and backform, the long 20mm-30mm of mating surface, and inclined-plane is with center line in 20-40 ° of acute angle；
Graphite pad is set in water pond and backform mating surface, by its higher capacity of heat transmission, it is ensured that the heat at backform center efficiently,
Quickly export.
The a length of 10mm in water annulus section, a width of 10mm, the Graphite pad thickness are 2mm.
The utility model is simple in construction, by the way that the cooling water pond for being machined with ring-type water channel is arranged on into backform central area,
, can be efficiently by thick large flange region by the powerful heat storage capacity of cooling water, and the excellent capacity of heat transmission of Graphite pad
Heat derives, it is achieved thereby that the quick cooled and solidified of wheel casting, eliminates the defects such as center porosity, shrinkage cavity；By adding
Big supercooling degree, makes internal grain obtain obvious refinement, significantly improves the mechanical property of core wheel；Realize to core wheel temperature
Effective control, reduce inside structural stress, reduce casting deformation, improve the dimensional accuracy of wheel.

Embodiment
As in Figure 2-4, aqueous cold plate 4 is arranged on the center of backform 1, to cool down thick big core wheel region, backform 1
It is located by connecting with aqueous cold plate 4 by M12 installation bolts 8, straight pin 7.
The inside of aqueous cold plate 4 sets water annulus 4-1, and rectangular cross-section, size is 10x10mm；Water annulus 4-1 baffle plates
Welded seal, it is ensured that current circulation is water-tight；Water inlet pipe 5 and outlet pipe 9, water inlet pipe 5 and outlet pipe are welded on water annulus 4-1
9, in 180 ° of distributions, farthest ensure the uniformity of cooling by water；Coordinate between aqueous cold plate 4 and backform 1 for inclined-plane, contact
The long 20-30mm in face, inclined-plane, in 20-40 ° of acute angle, thus can make cooling concentrate on core wheel region as far as possible with center line,
And reduce the influence to spoke position Temperature Distribution；Graphite pad 6 is set on water pond and backform mating surface, it is excellent by graphite
The capacity of heat transmission, it is ensured that backform center heat is efficiently exported, so as to realize the quick cooling of thick big core wheel.
By above-mentioned design, by circulation of the cooling water in aqueous cold plate, by the Graphite pad in mating surface, just
The heat in thick bull wheel heart district domain can efficiently be exported, so as to realize the quick cooling of casting, can eliminate wheel center shrinkage porosite,
The defects such as shrinkage cavity；The structure increases degree of supercooling, cast-internal crystal grain has been obtained obvious refinement, organizes finer and close, greatly
Width improves the mechanical property of core wheel；Meanwhile, effective control to core wheel temperature is realized, the structural stress of inside is reduced,
Casting deformation is reduced, the dimensional accuracy of wheel is improved.
