Description
Technical field
The invention belongs to wheel hubs to produce and process technical field, in particular to a kind of aluminium alloy kappa wheel hub casting mould.
Background technique
The wheel of truck and bus is much like in the prior art, so they are referred to as kappa wheel, i.e. kappa wheel packet
The wheel of truck and the wheel of bus are included, the kappa wheel in this specification refers to the wheel hub of kappa wheel.
Generally substitute original steel kappa wheel in industry using reflectal kappa wheel at present, it is light to reach wheel hub
The production technology of the purpose of quantization, existing forging kappa wheel is also unfavorable for producing in enormous quantities there are high production cost, simultaneously because
Kappa wheel product is higher for wheel rim and spoke mechanical property requirements, and conventional low pressure casting design scheme is difficult to meet it again to be wanted
It asks, it is easy to appear wheel rim and spoke are loose when production, and production efficiency is lower.Therefore the wheel hub of the production of existing production technology
It is high to sell unit price, is promoted in the market to influence to produce.
The wheel hub of current aluminium alloy still remains many defects in production technology and production equipment, such as low in aluminum vehicle wheel
During die casting is made, since aluminum vehicle wheel low pressure casting uses the pouring type of center rising pouring, pour, riser feeding is apart from remote, wheel
Wheel rim and spoke junction casting it is extremely thick big, form thermal center point, be easy to produce shrinkage porosite, the casting flaws such as shrinkage cavity.At present
Wheel hub manufacturing low pressure casting cooling technique generally uses air-cooled or two kinds of techniques of water cooling.There are production efficiencys for two kinds of techniques
It is low；Properties of product are unstable；Material property is difficult to meet the requirement of high-end product.
Chinese invention patent CN105478720B discloses a kind of water wind combination spraying cooling equipment of wheel hub low pressure casting
And method, the water fog generator including connecting wheel hub casting mould, water fog generator include cooling wind supervisor, cooling water master
Pipe and water mist cooling pipe, cooling water supervisor forms water mist with cooling wind supervisor's handover, and is transported to from water mist cooling pipe
Wheel hub casting mould, the technical effect of generation are that can improve the consistency of cast-internal tissue, improve product quality, reduce manufacture
Cost.Since bus wheel is compared to conventional wheel, have obvious feature in structure: 1, wheel rim is thicker, common wheel wheel
Rim blank thickness is in 8 ~ 9mm, and kappa wheel is since its load-carrying is larger, and rim blank thickness reaches 16 ~ 17mm thickness, and to drop center portion
The tissue intensity divided is more demanding；2, kappa wheel spoke is at dish-type, is evenly distributed with 10 air holes, the angle spoke R and spoke compared with
It is generous, referring to attached drawing 1.The art of this patent is also to be improved and produced by more complicated technical treatment on the basis of existing mold
Quality.The technical solution of the application is improved for the low pressure casting die of such a specific products of kappa wheel.Cause
Kappa wheel is compared to common wheel, and wheel rim thickness, which increases, to be connect by about one time, and wheel rim setting rate substantially reduces, and is easier to occur
Loose risk, influences rim strength, and the technical solution of the application also improves this.
Summary of the invention
The technical problems to be solved by the present invention are: a kind of aluminium alloy kappa wheel hub casting mould is provided, by low pressure

When have a stronger feeding, improve cooling velocity and feeding intensity, reach ZL101A aluminium alloy physical property and most strengthen, to mention
High product performance.
The present invention is achieved through the following technical solutions: a kind of aluminium alloy kappa wheel hub casting mould, including mold, described
Upper mould middle and upper part thickness is set as 25 millimeters to 60 millimeters, and side form middle and upper part thickness is set as 40 millimeters to 85 millimeters, the mould
The rim upper portion of tool is equipped with the first water cooling mouth, and wheel rim lower part is equipped with the second water cooling mouth, and spoke outer ring bed die is equipped with third water cooling mouth,
Cooling water is flowed by each water cooling mouth side to flow out behind cooling duct from other side.
Further, upper mould middle and upper part thickness is set as 30 millimeters to 55 millimeters, and side form middle and upper part thickness is set as
45 millimeters to 80 millimeters.
Further, the second water cooling mouth is fixed block insert type water cooling.
Further, spoke outer ring bed die is additionally provided with air-cooled mouth.
Further, the air-cooled mouth is preferably 6.
Further, the first water cooling mouth, the second water cooling mouth, third water cooling opening's edge circumferencial direction are set as a circle.
What the present invention realized has the beneficial effect that by, in wheel rim and spoke exterior design water cooling, adjusting to low pressure casting die
Reshaping die side form and the thickness of upper mold middle and upper part increase mold to the heat absorption coagulation ability of wheel rim middle and upper part, to realize preferable
Consecutive solidification, realize balanced mold temperature field, product each section allowed to have stronger feeding when solidifying, improve cooling velocity and
Feeding intensity reaches ZL101A aluminium alloy physical property and most strengthens, then be aided with it is appropriate air-cooled, to enhance product performance.
