Description
Technical field
The utility model is related to casting field, more particularly to a kind of low-pressure casting die of aluminum vehicle wheel.
Background technology
Low Pressure Casting Technology is the primary selection of domestic and international aluminum vehicle wheel manufacturer.Bed die, backform, side mould are together constituted
The die cavity of mould, high temperature aluminium liquid enter mold cavity by bottom centre's cast gate, in mould and the external world under the driving of outer boundary's pressure
Solidification forming is completed under the collective effect of cooling, obtains the qualified foundry goods of size, performance.The moulding flange center of wheel is thick big,
Wheel rim wall thickness is relatively thin, and spoke in centre as the coupling part of the two.But this distinctive moulding causes spoke and wheel rim
Junction is often very thick big, defines typical casting thermal center, this be obviously detrimental to realize wheel foundry goods consecutive solidification into
The requirement of shape.Practice have shown that, spoke is easy to shrinkage porosite, shrinkage cavity, degraded performance etc. casting problem occur with wheel rim handover region,
The waste product wheel for causing also accounts for larger ratio, seriously governs yield rate.In the prior art, the cooling at thermal center is usually logical
Cross and arrange a number of air channel to realize, but excessively concentrated due to heat, and the exchange capability of heat of air is relatively low, the region
Heat rapidly and effectively cannot shed at all, cause aluminium liquid setting rate slow, shrinkage porosite, contracting can occur because feeding is not enough
The forming defectses such as hole；In addition, aluminium liquid degree of supercooling during solidification also can be relatively low accordingly, cast-internal coarse grains are caused, organized
Not fine and close, mechanical property is low, and these all serious shaping qualities for affecting wheel govern the development of enterprise.
Therefore, for the problem that there is currently, need to carry out certain improvement, set by optimizing the cooling in thermal center region
Meter, realizes the quick cooling of aluminium liquid, the problems such as easily there is shrinkage porosite, shrinkage cavity, degraded performance so as to effectively solving thermal center, to ensure car
The fine quality of wheel, and meet the sample presentation requirement of client.
Content of the invention
The purpose of this utility model is to provide a kind of low-pressure casting die of aluminum vehicle wheel for improving, it is possible to achieve thermal center region
Quick cooling, it is established that beneficial to the temperature field that consecutive solidification realized by wheel, so as to easily occur in effectively solving production shrinkage porosite,
The problems such as shrinkage cavity.
The technical solution of the utility model is：A kind of improved low pressure casting wheel mould, including backform, bed die, Bian Mo,
Heat-conducting pad, annular conduit, cover plate, insulation asbestos.
Cylindrical boss is set at the corresponding thermal center of bed die back of the body chamber root, number is consistent with spoke quantity, and which is used as thermal center position
Put a little cold cooling source；U-shaped groove being set on boss, and heat-conducting pad being placed in groove, heat-conducting pad selects red copper, graphite
Material, thickness 1-3mm；The annular conduit that makes is placed on the pad in groove, water pipe bottom will be higher by cylindrical boss
End face, to ensure that cover plate can be firmly secured in groove, and realizes the good fit of water pipe and heat-conducting pad；Cover plate with
The spot welding of bed die boss connects；Annular conduit internal diameter is 8-12mm, and is welded with water-in and water-out pipe joint, is arranged symmetrically in 180 °, can
Ensure uniformity during cooling；Supplying pipe selects stainless steel tube, it is to avoid the adverse effect that scale is generated；Water pipe is away from bed die die cavity
Face 30-40mm, to ensure rational intensity of cooling so as to is not too strong or excessively weak；Cylindrical boss front end processing every
Heat channel, bottom land fill up insulation asbestos in groove away from mould cavity surface 10-20mm, control cooling range in thermal center region as far as possible
Interior, reduce the impact to thermal center head temperature, so as to ensure the good feeding of aluminium liquid.
The utility model simple structure, has carried out rational improvement to die structure, for spoke thermal center region, processes
Cylindrical boss by cooling control in the range of thermal center, and does not affect the Temperature Distribution of front end, it is achieved that more smart as cooling source
True refrigeration；Existing air-cooled by the replacement of water pipe cooling form, intensity of cooling is significantly strengthened, the solidification of aluminium liquid is improve
Speed, it is achieved that the quick cooling of foundry goods, effectively solves the problems, such as easily occur shrinkage porosite, shrinkage cavity at thermal center；Meanwhile, aluminium liquid
Degree of supercooling there has also been significantly increasing, makes internal grain obtain obvious refinement, greatly improves the mechanical property of foundry goods.
