Abstract
A kind of low-pressure casting die of aluminium alloy wheel, including bed die（1）, backform（2）, Bian Mo（3）Deng.Bian Mo（3）It is equipped with side molding pressure feeding plug（5）；Backform（2 are equipped with backform pressure feeding plug（4）, the bed die centre position is equipped with direct cooling water channel（6）, bed die cooling water channel（6）Cross-sectional area diameter is no more than 10mm, and bed die cooling water channel is no less than 15mm apart from mold cavity surface.The aluminum vehicle wheel spoke material mechanical property better quality of the utility model order production, beneficial to realizing product lightweight, while also improves production efficiency.
Description
Technical field
It the utility model is related to a kind of aluminum alloy low-pressure casting mould.
Background technology
At present, conventional low foundry technology process is：Molten aluminum rises under drying compressed air effect through stalk, passes through
Trumpet assembly steadily enters mold cavity, fills holding insulation furnace inner gas pressure after the completion of type, molten aluminum is by wheel distalmost end
Wheel rim starts to consecutive solidification at wheel flange center cast gate, after casting solidification is fully completed, releases compressed air in holding furnace
Pressure, the molten aluminum below cast gate is back in holding furnace, mold pickup, complete the aluminum vehicle wheel low pressure casting mistake of a cycle
Journey.
The aluminum-alloy wheel casting solidification of the prior art, by single trumpet assembly feeding, solidification sequence is lubrication groove successively
Edge, wheel rim, spoke, core wheel.In actual order process of setting, the solidification of spoke is delayed in order to wait wheel rim preferentially to solidify
On opportunity, cause spoke shrinkage defect, or spoke to solidify the relatively low quality problems of slow material mechanical performance；Casting is stringent from upper
Casting beat is partially slow down, production efficiency is relatively low for consecutive solidification condition constraint under and, from outside to inside.
The content of the invention
The utility model provides a kind of quickening casting beat, improves production efficiency；Improve the aluminium alloy of the quality of casting
Wheel pressure casting mould.
The technical solution of the utility model is a kind of low-pressure casting die of aluminium alloy wheel, including backform, bed die and
Bian Mo, the side mould are equipped with multiple pressure feeding plugs；Backform is equipped with multiple pressure feeding plugs；Pressure feeding plug and compression
It is air connected.Bed die center is equipped with a cast gate, and bed die corresponds to spoke centre position and sets annular cooling water road.
The bed die cooling water channel, cross-sectional area diameter are no more than 10mm, and water channel is no less than apart from mold cavity surface
15mm。
The pressure feeding plug, using uniformly distributed form, the distance of adjacent feeding plug is not less than 15mm.
The beneficial effects of the utility model are that under the conditions of compressed air pressure feeding, aluminium alloy wheel rim is inside and outside
The shortening of wheel rim thickness general goal crystallization and freezing time, aluminum-alloy wheel spoke contract in trumpet assembly and outer rim thickness general goal feeding distance
Annular direct cooling water channel short, that matching bottom mould is set, spoke crystallization and freezing is in advance and setting time is shorter, the aluminium car of production
Spoke material mechanical property better quality is taken turns, beneficial to realizing product lightweight, while also improves production efficiency.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structure diagram of the low-pressure casting die of aluminium alloy wheel of the utility model.
1. bed die in Fig. 1,2. backforms, 3. side moulds, 4. backform pressure feeding plugs, 5. side molding pressure feeding plugs, 6. bed dies are cold
But water channel, 7. cast gates.
Embodiment
A kind of low-pressure casting die of aluminium alloy wheel, including backform 2, bed die 1 and Bian Mo 3, it is described when being equipped with mould 3
Molding pressure feeding plug 5；Backform 2 is equipped with backform pressure feeding plug 4；Side molding pressure feeding plug 5, backform pressure feeding plug 4 and pressure
Contracting is air connected.Bed die center is equipped with cast gate 7, and bed die corresponds to spoke centre position and sets annular cooling water road 6.
Such as Fig. 1, backform pressure feeding plug 4 is arranged on the thick big inner rim position of casting, and edge on backform 2, is conducive to molten aluminum
It is vented when filling type.While molding pressure feeding plug 5 be arranged on the thick big inside and outside rim location of casting it is corresponding while 3 cavity of mould on.Bed die
Cooling water channel is arranged on the most thin position of spoke thickness.
The bed die cooling water channel 6, cross-sectional area diameter are no more than 10mm, and water channel is no less than apart from mold cavity surface
15mm。
Side molding pressure feeding plug 5, backform pressure feeding plug 4, using uniformly distributed form, the distance of adjacent feeding plug is not less than
15mm。
During specific works, molten aluminum is filled into mold cavity by the cast gate for being arranged on bed die center, in cavity filling process
Gap discharge of the air through pressure feeding plug in mold cavity.Type completion is filled, after crusting at the interior outer rim of casting, is opened
Compressed air at pressure feeding plug, pressure to 0.6MPa, pressure is removed after casting all solidification.Wheel rim solidifies under stress
After the completion of, starting bed die cooling water, casting is solidified since centre at spoke, while multipoint pressure feeding at the molding pressure plug of side,
The effect of center feeding is also functioned at trumpet assembly, until removing pressure after gradually all solidifying, takes out casting, completes low pressure casting
Make technical process.
