The utility model discloses impurity in can elimination aluminium liquid reduces the aluminium liquid stream and moves speed, improves aluminium liquid density, has improved product quality.
Description
Technical field
The utility model relates to a kind of double medium filtration sprue bush, is mainly used in casting field in aluminum alloy casting technique.
Background technology
In existing aluminium alloy casting casting process, sprue bush generally adopts straight barrel type, and aluminium liquid flows into mould molding by casting gate, and aluminium liquid flowing velocity is fast, and the liquid-tight degree of aluminium is little, and impurity remaining in aluminium liquid, all can affect product quality.
Utility model content
The purpose of this utility model is to provide a kind of double medium filtration sprue bush, can impurity in elimination aluminium liquid, reduces aluminium liquid flowing velocity, improves the liquid-tight degree of aluminium, improve product quality.
Double medium filtration sprue bush described in the utility model, comprises body, and body comprises the internal layer and skin that are set in together, and internal layer comprises the upper conical portion of the internal layer set gradually from top to bottom, internal layer curved portions and internal layer inferior pyramidal portion; Skin comprises the upper conical portion of the skin set gradually from top to bottom, outer curved portions and outer inferior pyramidal portion; Inner layer outer surface and outer inner chamber adapt; Bottom, internal layer inferior pyramidal portion is provided with coarse strainer, and internal layer inferior pyramidal is provided with fie screen in the middle part of portion, and coarse strainer and fie screen are evenly arranged filter bores; Coarse strainer is titanium nitride ceramic coarse strainer; Fie screen is titanium nitride ceramic fie screen.
Fie screen filter bores diameter is less than coarse strainer filter bores diameter, and fie screen can filter out fine impurities, meanwhile, can hinder aluminium liquid flowing velocity, improves the liquid-tight degree of aluminium, improves the quality of products; Coarse strainer is titanium nitride ceramic coarse strainer; Fie screen is titanium nitride ceramic fie screen, does not fall slag and is not stained with aluminium, do not pollute aluminium liquid, improve product quality.
Described internal layer is titanium nitride ceramic internal layer.Do not fall slag and be not stained with aluminium, do not pollute aluminium liquid, improve product quality.
Described internal layer upper conical portion upper end open is large; Described internal layer inferior pyramidal subordinate end opening is large; Described internal layer upper conical portion inner cavity taper is 1-80 degree, and internal layer inferior pyramidal portion inner cavity taper is 1-80 degree; Aluminium liquid flowing velocity can be hindered, improve the liquid-tight degree of aluminium, improve the quality of products.
Described skin is that aluminum silicate ceramic is outer.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model is by arranging titanium nitride ceramic coarse strainer and titanium nitride ceramic fie screen, itself does not fall slag and is not stained with aluminium, effectively can remove the impurity in aluminium liquid, improve product quality;
(2) by arranging the internal layer and skin that are set in together, internal layer is titanium nitride ceramic internal layer, and skin is that aluminum silicate ceramic is outer; Be not stained with aluminium and do not fall slag, improve the quality of products, corrosion resistance is strong, and long service life, cost is low.
(3) internal layer comprises the upper conical portion of the internal layer set gradually from top to bottom, internal layer curved portions and internal layer inferior pyramidal portion; Skin comprises the upper conical portion of the skin set gradually from top to bottom, outer curved portions and outer inferior pyramidal portion; Improve the liquid-tight degree of aluminium, improve the quality of products.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the present utility model.
In figure: 1, the upper conical portion of internal layer 2, outer upper conical portion 3, internal layer curved portions 4, outer curved portions 5, internal layer inferior pyramidal portion 6, fie screen 7, outer inferior pyramidal portion 8, coarse strainer.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further:
As shown in Figure 1, double medium filtration sprue bush described in the utility model, comprises body, and body comprises the internal layer and skin that are set in together, and internal layer comprises the upper conical portion 1 of the internal layer set gradually from top to bottom, internal layer curved portions 3 and internal layer inferior pyramidal portion 5; Skin comprises the upper conical portion of the skin set gradually from top to bottom 2, outer curved portions 4 and outer inferior pyramidal portion 7; Inner layer outer surface and outer inner chamber adapt; Bottom, internal layer inferior pyramidal portion 5 is provided with coarse strainer 8, is provided with fie screen 6 in the middle part of internal layer inferior pyramidal portion 5, and coarse strainer 8 and fie screen 6 are evenly arranged filter bores; Coarse strainer 8 is titanium nitride ceramic coarse strainer; Fie screen 6 is titanium nitride ceramic fie screen.
Internal layer is titanium nitride ceramic internal layer.Internal layer upper conical portion 1 upper end open is large; Internal layer inferior pyramidal portion 5 lower ending opening is large; Internal layer upper conical portion 1 inner cavity taper is 15 degree; Internal layer inferior pyramidal portion 5 inner cavity taper is 15 degree.Skin is that aluminum silicate ceramic is outer.
The course of work:
Aluminium liquid enters body from coarse strainer 8, filters further through fie screen 6, and fie screen 6 filter bores diameter is less than coarse strainer 8 filter bores diameter, fie screen 6 can filter out fine impurities further, meanwhile, hinders aluminium liquid flowing velocity, improve the liquid-tight degree of aluminium, improve the quality of products; Coarse strainer 8 is titanium nitride ceramic coarse strainer; Fie screen 6 is titanium nitride ceramic fie screen, does not fall slag and is not stained with aluminium, do not pollute aluminium liquid, improve product quality.
