Description
Technical field
The present invention relates to machine casting technical field, and in particular to a kind of water-cooled hub mold.
Background technology
Wheel hub as one of most important moving component of automobile, to its performance, weight, service life have it is very high will
Ask.At present, aluminium alloy wheel hub with its light weight, rapid heat dissipation, good damping performance, long lifespan, balanced the advantages of, in auto industry
In show one's talent.
Aluminium alloy wheel hub is typically produced by the way of casting, and the mould for casting hub mainly includes upper mould
Tool, lower mould, side mold and base, after the combination of the mold, lower mould and side mold, form the cast moulding of wheel hub to be cast
Chamber, described lower mould and side mold are each attached on base.During cast, fed to die cavity from the sprue gate on lower mould
It is filled, in process of setting after being cast, the region that the boundary place of mold, lower mould and side mold is formed is casting
The thermal center point of wheel hub, for the structure of wheel hub, above-mentioned thermal center point refers to the handing-over intermediate location between spoke and wheel rim, due to
Wheel hub is generally circular in cross section, and the intermediate location is also just annulus, i.e., the intermediate location of whole annular is thermal center point, the wall at the position
Thicker, cooling velocity is slower after cast, and spoke and the wall thickness of wheel rim adjacent thereto is then relatively thin, cooling velocity compared with
Hurry up, so being also easy to produce the defect such as shrinkage cavity, loose on hub cast blank in this place, influence hub cast blank quality, spoke
The general Ye Weihou great areas in center, the position casting volume is maximum, and cooling is extremely difficult, but for aluminium alloy wheel hub, it is cold
Faster wheel hub intensity is better, according to prior art, high-pressure water-cooling device is provided with hub mold, is poured in mould cooling pipe
Water under high pressure, wheel hub can be cooled down quickly, bigger several times than common intensity of cooling, but wheel hub cooling needs consecutive solidification,
Described consecutive solidification refers to that the solidification of casting is carried out to center from surface, from being solidified at first away from sprue gate part, then
It is proximate to sprue gate partially solidified, is finally that sprue gate solidifies in itself, consecutive solidification solidifies position to first solidification portion after can makes
The supplement expected of position, reduces shrinkage cavity and loose as far as possible, and to sprue gate, cooling velocity is fast in itself with high pressure water cooling, it is impossible to reach
To the effect of consecutive solidification, casting scrappage is high, low production efficiency.
The content of the invention
The technical problems to be solved by the invention are：Overcome the defect of above prior art, there is provided a kind of cooling velocity is fast
