Description
Technical field
The present invention relates to machine casting technical field, more particularly to a kind of hub mold tread ring water-cooling apparatus.
Background technology
Wheel hub as one of most important moving component of automobile, have to its performance, weight, service life 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 mould, lower mould and side mold combination, form the casting mold cavity of wheel hub to be cast, under
Mould and side mold are each attached on base.During cast, die cavity is filled from the sprue gate charging on lower mould,
In process of setting after cast, the region of the boundary place formation of mold, lower mould and side mold is the thermal center of casting hub
Point, for the structure of wheel hub, above-mentioned thermal center point refers to the handing-over intermediate location between spoke and wheel rim, because wheel hub is generally
Circle, the intermediate location is also just annulus, i.e., the intermediate location of whole annular is thermal center point, and the wall thickness at the position is thicker, pours
Cooling velocity is slower after note, and spoke adjacent thereto and the wall thickness of wheel rim are then relatively thin, and cooling velocity is very fast, so at this
Be also easy to produce shrinkage cavity on the hub cast blank at place, the defect such as loose, influence hub cast blank quality, spoke centre position is general
Ye Weihou great areas, the position casting volume is maximum, and cooling is extremely difficult, but for aluminium alloy wheel hub, cools down faster wheel hub strong
Degree is better.
Existing automobile aluminum wheel hub low pressure casting die is not provided with cooling system at spoke corner thermal center and at rear extension
System, can reach consecutive solidification to meet product casting, can only increase the temperature of spoke part and trumpet assembly part, and prolong
Long casting cycle, low production efficiency.It can be seen that, if the local easily loose, overheat of wheel hub can not caused to being cooled down rapidly at thermal center point
The easy not enough, tension and extension numerical value is not up to standard and 90 degree of impacts were not easy of the gas leakage of Shi Houdao handling eases, mechanical performance,
In addition, mould bulk temperature height causes casting cycle longer.
In view of above-mentioned defect, the design people is actively subject to research and innovation, to found a kind of wheel hub of new structure
Mould tread ring water-cooling apparatus, makes it with more the value in industry.
The content of the invention
It is an object of the invention to propose a kind of hub mold tread ring water-cooling apparatus, hub mold is enabled in casting
Avoid overheat, wheel hub in the middle part of wheel hub locally loose during wheel hub, and the casting cycle of mould can be shortened.
For up to this purpose, the present invention uses following technical scheme：
Hub mold tread ring water-cooling apparatus, including it is coaxial and can be installed on described with the upper mould of the hub mold
The tread ring body of ring-type at mould thermal center point, the tread ring body is provided with adjacent water inlet and delivery port and described in connect
The cooling water channel of water inlet and the delivery port, and the cooling water channel press close to that the tread ring body contacts with the upper mould it is outer
Wall.
Further, the cooling water channel by multiple elongated holes being drilled with along the tread ring body outer wall successively interconnection and
Into head end is docked with the water inlet and the delivery port respectively with the end of the elongated hole of end；And the elongated hole is located at
The welded closing in end of the tread ring body outer wall.
Further, the cooling water channel is the recessed ring coaxial on the tread ring body and with the tread ring body
Groove, the annular groove is major arc shape and its two ends is docked with the water inlet and the delivery port respectively, is welded with the annular groove
Matched annular cover plate.
Further, the water inlet be equipped with the inwall of the delivery port after multiple closures can seal it is described cold
But the valve of water channel.
Further, collar of the water inlet with being respectively connected with clamping water pipe on the inwall of the delivery port.
Further, at least provided with a mounting hole on the tread ring body.
Further, enclosed on the upper mould inwall along its flexible metal for being circumferentially with tread ring body described in clamping.
Beneficial effects of the present invention are：Tread ring body can be cooled down in casting hub to the hot position of joints of upper mould,
Casting is set preferably to be solidified at first from away from sprue gate part, followed by it is partially solidified close to sprue gate, it is finally sprue gate
Itself solidifies, it is to avoid rear solidification position and hot node location occur shrinkage cavity because of the supplement that can not be expected or loose grade lacks
Fall into, make the reduction of casting wasted product rate, and then improve production efficiency, while cooling to mould, casting cycle can be shortened.
