Abstract
The utility model discloses a kind of sprue bush for aluminum alloy low-pressure casting process, comprise skeleton and internal and external walls coating.Described skeleton is metallic framework, and the inwall of described skeleton is provided with high temperature corrosion-resisting and is not stained with aluminium ceramic coating, and the outer wall of described skeleton is sprayed with soak material coating.The utility model is corrosion-resistant because inwall is provided with is not stained with aluminium ceramic coating, outer wall is provided with soak coating, not only high insulating effect, and there is corrosion resistance and impel casting sprue easily to extract, avoid breaking and water lip reflex, owing to employing metallic framework, solve the problem that ceramic sprue bush is frangible, multiple casting cycle can be applied to, long service life, reduce costs.
Description
Technical field
The utility model relates to aluminum alloy low-pressure casting process technical field, especially relates to the sprue bush for aluminum alloy low-pressure casting process.
Background technology
In aluminum alloy low-pressure casting process, running gate system is particularly important, and its effect not only makes aluminium alloy liquid be full of mold cavity reposefully, also will play the effect of feeding in blank solidification stages, to obtain the foundry goods of internal organizational structure densification.Sprue bush is a vitals of aluminum alloy low-pressure casting process running gate system, just as bottleneck, can be referred to as the throat of casting system, and its structural design and selection are filled type to aluminium alloy liquid and solidified material impact.Direct use metal sprue bush, due to the severe corrosive of aluminium alloy liquid, the corrosion product of sprue bush can be cast liquid and be brought in foundry goods and produce waste product.At present, be corroded to prevent sprue bush and improve heat insulation effect, usually adopting ceramic sprue bush, but due to ceramic sprue bush frangible and two or more casting cycle can not be used for, expense cost is very large.
Summary of the invention
The purpose of this utility model is to provide that a kind of corrosion resistance for aluminum alloy low-pressure casting is strong, the sprue bush of high insulating effect and long service life.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: the sprue bush for aluminum alloy low-pressure casting comprises skeleton and internal and external walls coating.The inwall of described skeleton is that high temperature corrosion-resisting is not stained with aluminium titanium boride coating, and the outer wall of described skeleton is soak material oxidation zirconium coating.
Further, described skeleton is hot-cast die steel material, as H13.
Titanium boride, chemical formula is TiB2, is the structural material of a kind of high-melting-point, high rigidity.It has resist melt metal erosion and is not stained with the characteristic of aluminium, is commonly used to manufacture the crucible for motlten metal and electrolytic cell electrode.
Zirconia, chemical formula is ZrO2, is a kind of dystectic exotic material.Due to the coefficient of heat conduction that it is extremely low, be used as thermal barrier coating at aerospace field.
Good effect of the present utility model is: adopt technique scheme, uses titanium boride as inboard wall of skeleton coating material, makes described sprue bush have the corrosion of resistance to aluminium, be not stained with the advantage of aluminium, waters lip reflex to obtain the low premium casting of impurity content and not occur breaking; Due to the zirconia coating using the coefficient of heat conduction minimum, described sprue bush has the feature of good heat preservation performance, in low-pressure casting process, is easy to feeding, to obtain the foundry goods of internal organizational structure densification; Because skeleton is metal material, according to the needs of low-pressure casting process, design and fabrication can be easy to, and can not be broken, long service life, reduces manufacturing cost simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, metallic framework inwall 2, metallic framework outer wall.
Detailed description of the invention
As shown in Figure 1, for the sprue bush of aluminum alloy low-pressure casting process, comprise skeleton and internal and external walls coating.Described skeleton is metallic framework, and the inwall of described skeleton is provided with high temperature corrosion-resisting and is not stained with aluminium ceramic coating, and the outer wall of described skeleton is sprayed with soak material coating.
The inwall of described skeleton is TiB2 coating, and the outer wall of described skeleton is ZrO2 coating.
Application process of the present utility model is: during use, and sprue bush is located at one end of running gate system stalk, and the other end of sprue bush is connected with die cavity, is equivalent to " neck " that connect running gate system and casting system.
Above an embodiment of the present utility model is described in further detail; but described content is only preferred embodiment of the present utility model; not in order to limit the utility model; all equalizations of carrying out according to principle of the present utility model change and improve, and all should still belong in scope of patent protection of the present utility model.
