Description
Technical field
It the utility model is related to metal working technical area, and in particular to the fire-retardant anti-oxidation guarantor of aviation casing Mg alloy castings
The improved technology of warm dead head structure.
Background technology
Magnesium alloy is adapted to apply in specific field, such as aviation field.Magnesium alloy high is subtracted with it than performance, protrusion
Suction of shaking is made an uproar ability, good forming processing performance and the features such as be easily recycled, and is described as the green knot of 21 century
Structure material.Magnesium alloy is prone to oxidizing fire in melting, liquid forming and heat treatment process, it is desirable to provide effective fire-retardant
Protection.At high temperature, fire-retardant especially under molten condition is for magnesium and its alloy:Using method physically or chemically, on its surface
Effective protection aquiclude is formed, on the one hand completely cuts off air, on the one hand prevents magnesium from evaporating, reach and slow down oxidation, fire-retardant purpose.
It can mitigate weight, the mobility for improving aerospace vehicle using the aviation casing of magnesium alloy, reduce oil consumption, band
Carry out considerable economic benefit.
During fabrication, the effect of insulated feeder is to be emitted by extending rising head setting time to improve to the aviation casing of magnesium alloy
The feeding efficiency of mouth.In Foundry Production, it is one of important measures for ensureing casting quality to set rising head, and its main function is pair
Casting carries out feeding.Existing aviation casing Mg alloy castings insulated feeder is usually V-arrangement or stairstepping, because this structure emits
Larger, the rapid heat dissipation of mouth opening, influence the feeding performance of rising head.
The content of the invention
The utility model provides the fire-retardant anti-oxidation insulated feeder of aviation casing Mg alloy castings, and the utility model solves magnesium
The aviation casing Mg alloy castings insulated feeder of alloy is usually V-arrangement or stairstepping, rapid heat dissipation, influences the feeding performance of rising head
Problem.
To solve the above problems, the utility model adopts the following technical scheme that:The fire-retardant oxygen of aviation casing Mg alloy castings
Change insulated feeder, including aviation casing casting body, have spherical feeding insulated feeder above aviation casing casting body;It is spherical
Feeding insulated feeder top is spherical, bottom is inverted-cone shape structure, and spherical feeding insulated feeder internal layer is in titanium dioxide silica brick
Layer rising head, centre are that alumina silicate heat-insulation layer, outer layer are outer layer molds;Funnel shaped casting is connected above spherical feeding insulated feeder
Mouthful.
The utility model advantage:Spherical feeding insulated feeder is designed with, rising head can accommodate more raw material, riser openings
Smaller, radiating is few, improves heat insulating ability.Rising head uses alumina silicate heat-insulation layer, high insulating effect, the product quality stabilization of production.
Brief description of the drawings
Fig. 1 is the utility model structure diagram.
Symbol description in figure:Aviation casing casting body 1, casting nozzle 2, spherical feeding insulated feeder 3, alumina silicate heat-insulation layer 4,
Titanium dioxide silica brick internal layer rising head 5, outer layer mold 6.
Embodiment
The utility model is described in detail with optimal embodiment below.
As shown in figure 1, the superpower feeding insulated feeder of aviation casing magnesium alloy casting, including aviation casing casting body 1,
Aviation casing casting body 1 has spherical feeding insulated feeder 3 above;The spherical top of feeding insulated feeder 3 is spherical, bottom is down
Put pyramidal structure, the spherical internal layer of feeding insulated feeder 3 be titanium dioxide silica brick internal layer rising head 5, centre be alumina silicate heat-insulation layer 4, it is outer
Layer is outer layer mold 6;Spherical feeding insulated feeder 3 connects funnel shaped casting nozzle 2 above.
The top of spherical feeding insulated feeder is spheroidal, and here is inverted-cone shape structure, is easy to spherical feeding insulation to emit
Intraoral raw material is injected into casting.Spherical feeding insulated feeder diameter is formulated according to design requirement.Spherical feeding insulated feeder
It is interior to accommodate more raw material.Spherical feeding insulated feeder top connects funnel shaped casting nozzle, is easy to supplement injection liquid.By
Small in spherical feeding insulated feeder upper port and funnel shaped casting nozzle junction port, radiating is small, heat-insulating property increase.Using silicon
Sour aluminium heat-insulation layer be using hard paste clinker as raw material, be substitute asbestos heat insulating material, the heatproof of aluminium silicate wool:800-
1200 degrees Celsius.
Titanium dioxide silica brick internal layer rising head of the present utility model, be using earth silicon material fire form, method for cooking with
Silica brick producing process is identical.Titanium dioxide silica brick internal layer rising head is that casting mold is interior for storing feeding a casting molten metal, and
Exhaust, the cavity of collection slag effect can be designed, to avoid casting from the supplement knot that defect is attached to above casting or side occur
Structure.
Finally it should be noted that:Obviously, above-described embodiment is only intended to clearly illustrate the utility model example,
And the restriction not to embodiment.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no necessity and possibility to exhaust all the enbodiments.And thus
Among the obvious changes or variations amplified out is still in the scope of protection of the utility model.
