Abstract
The utility model discloses a kind of low-pressure casting die of aluminum vehicle wheel, comprise water-cooled block, bed die, Bian Mo and backform, have annular water-cooling channel in described water-cooled block, described aqueous cold plate arranges water-cooled water inlet pipe, water-cooled outlet pipe and trip bolt.By the mode that water-cooled block and backform split design, both thick large inner rim can be cooled fast, be unlikely to again the wheel rim feeding time that strong water-cooled function influence wall thickness is thin, when casting thickness is upper thick and lower thin, still create top-down consecutive solidification gradient condition, thus castings is cast out under the prerequisite not increasing wheel rim allowance thickness, improve casting technique yield rate, decrease the waste of waste product material cost.
Description
Technical field
The utility model relates to casting aluminum wheels field, is specifically a kind of low pressure casting die.
Background technology
At present, domestic and international market for automobiles requires constantly to increase to the lightweight of car load and comfortableness, so have influence on aluminum vehicle wheel parts just need product loss of weight while also need to increase the rigidity of wheel to ensure the comfortableness of driving.So, just need when wheel design consideration to thicken inner rim based on the demand and improve wheel rate, need thinning wheel rim thickness with leveling wheel loss of weight simultaneously, realize lightweight target.But under the trend that product-forming is thicker at inner rim, wheel rim is thinner, run counter to the thickness gradient of the consecutive solidification from top to bottom principle of low pressure casting aluminum vehicle wheel, will certainly shrinkage defect be produced, cause qualified casting to decline.Based on above-mentioned, be necessary, for aluminum vehicle wheel product variations trend, to improve existing die design method.
Summary of the invention
The technical problems to be solved in the utility model is, under the prerequisite not thickening wheel rim machining allowance, realizes the consecutive solidification of upper thick and lower thin structure aluminum wheel product, eliminates casting shrinkage defect.
The technical solution of the utility model is, a kind of low-pressure casting die of aluminum vehicle wheel, comprises water-cooled block, bed die, Bian Mo and backform, and have annular water-cooling channel in described water-cooled block, water-cooled block is connected with backform by trip bolt.
As improvement, be the water-cooling channel of annular cooling in described water-cooled block, the interface of water-cooled water inlet pipe, water-cooled outlet pipe all arranges partition, avoids Inlet and outlet water to flow backwards, affects heat transfer effect.
As improvement, the water-cooled water inlet pipe of water-cooling channel and each two of water-cooled outlet pipe, interlaced arrangement, ensures that large scale mold temperature is balanced consistent.
As improvement, water-cooling channel adopts welded seal, reduces difficulty of processing, reduces manufacturing cost.
As improvement, both by the separately design of water-cooled block and backform, and connect with trip bolt by this mould, and the excessively strong cooling of divisible water-cooled is on the impact of the wheel rim of thin-walled, and trip bolt requires to be evenly arranged simultaneously.
As improvement, the thick large part inner rim of water-cooling channel direct water-cooling cooling foundry goods far-end, utilize the mode of water-cooled block and backform split, spaced apart water-cooled produces the impact of shrinkage defect on the strong water-cooled of thin-walled position wheel rim, manufacture a top-down consecutive solidification gradient, obtain good foundry goods.
Compared with original technology, the utility model has the following advantages: the cooling by water mode changing the thick large aluminum vehicle wheel product of inner rim, by means of only the mode that water-cooled block and backform split design, both thick large inner rim can be cooled fast, be unlikely to again the wheel rim feeding time that strong water-cooled function influence wall thickness is thin, when casting thickness is upper thick and lower thin, still create top-down consecutive solidification gradient condition, thus castings is cast out under the prerequisite not increasing wheel rim allowance thickness, improve casting technique yield rate, decrease the waste of waste product material cost.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of low-pressure casting die of aluminum vehicle wheel of the utility model.
Fig. 2 is the partial schematic diagram of water-cooled water inlet pipe and water outlet pipe interlaced arrangement of the present utility model.
In figure: 10-water-cooled block, 11-bed die, 12-limit mould, 13-backform, 20-water-cooling channel, 21-water-cooled water inlet pipe, 22-water-cooled outlet pipe, 23-trip bolt, 30-wheel inner rim, 31-rim for automobile wheel.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, 2, a kind of low-pressure casting die of aluminum vehicle wheel, comprise water-cooled block 10, bed die 11, limit mould 12 and backform 13, described water-cooled block 10 is provided with water-cooling channel 20, water-cooled block 10 is connected with backform 13 by trip bolt 23, and described water-cooling channel 20 is provided with water-cooled water inlet pipe 21 and water-cooled outlet pipe 22.
In order to split water-cooled block 10 cooling effect uniformity, water-cooling channel 20 arranges water-cooled water inlet pipe 21 and each two of water-cooled outlet pipe 22, and interlaced arrangement, the interface of water-cooled water inlet pipe 21, water-cooled outlet pipe 22 all arranges partition.
In order to reduce the difficulty of processing of split water-cooled block 10, reduce manufacturing cost, water-cooling channel 20 adopts welded seal.
In order to obtain the second best in quality foundry goods, split water-cooled design is adopted for upper thick and lower thin aluminum vehicle wheel product, the thick large part inner rim 30 of water-cooling channel 20 direct water-cooling cooling foundry goods far-end, utilize the mode of water-cooled block 10 and backform 13 split, spaced apart water-cooled produces the impact of shrinkage defect on the strong water-cooled of thin-walled position wheel rim 31, manufacture a top-down consecutive solidification condition.
Below be only described with regard to the utility model preferred embodiment, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete steps allow to change, and water-cooling channel can not adopt water annulus mode, and replaceable is polygonal countersink mode, only allows to arrange evenly to realize the object cooling thick large wheel rim fast.In a word, all various changes done in the protection domain of the utility model independent claims are all in protection domain of the present utility model.
