Abstract
The invention discloses a kind of improved low pressure casting die sprue bush, including sprue bush main body, projection, insulation material, square fixed block, cast passage, it is characterized in that：The sprue bush main body is fixed on fixed structure middle part by square fixed block, the sprue bush main body top is connected by projection with the sprue gate of bed die, leave cast channel design in the sprue bush main body middle part, the cast channel middle and top are mounted on foam ceramic filter, the cast passage outside is filled with insulation material, the cast passage bottom is provided with rectangle concave block structure for being connected with stalk, and the ceramic filter is provided with mesh on the net.The improved low pressure casting die sprue bush, high insulating effect, and make simple reduces sprue bush cost, being mingled with and slag inclusion with filtering metal liquid, improve the qualification rate of the body of casting, the sprue bush is reasonable in design, low cost, is adapted to widely promote the use of.
Description
Technical field
The present invention relates to Low Pressure Casting Technology field, specially a kind of improved low pressure casting die sprue bush.
Background technology
Sprue bush has been widely used on low pressure die casting mould; can be very good to protect mould; but sprue bush is all mostly common structure; simple metal alloy is made; heat insulation effect is poor, outside have added with heating arrangement, not only increase cost; and heat insulation effect, nor highly desirable, little cast gate has been arranged with leakage-proof structure and filtration.
The content of the invention
It is an object of the invention to provide a kind of improved low pressure casting die sprue bush, to solve the problems, such as to be proposed in above-mentioned background technology.
To achieve the above object, the present invention provides following technical scheme：A kind of improved low pressure casting die sprue bush, including sprue bush main body, projection, foam ceramic filter, insulation material, square fixed block, cast passage, the sprue bush main body is fixed on fixed structure middle part by square fixed block, the sprue bush main body top is connected by projection with the sprue gate of bed die, projection can prevent molten metal side leakage, leave cast channel design in the sprue bush main body middle part, the cast channel middle and top are mounted on foam ceramic filter, the cast passage outside is filled with insulation material, preventing body of casting molten metal during the cooling can not carry out feeding in being set in sprue bush to the body of casting, the cast passage bottom is connected by rectangle concave block structure with stalk, the ceramic filter is provided with mesh on the net.
Preferably, the cast passage is two intersecting trapezoidal shape structures, and top and bottom are respectively kept with projection and rectangle concave block structure.
Preferably, the sprue bush body outer wall is stainless steel structure, and inwall is ceramic structure and foam ceramic filter and the ceramic structure of inwall is formed in one structure.
Preferably, the mesh is rounding wimble structure.
Compared with prior art, the beneficial effects of the invention are as follows：The improved low pressure casting die sprue bush, inwall is provided with ceramic structure and insulation material is filled in interlayer, high insulating effect, and make simple, reduce sprue bush cost, there is ceramic filter web frame at middle and top, can being mingled with and slag inclusion with filtering metal liquid, the qualification rate of the body of casting is improve, top and bottom are equipped with the projection and rectangle concave block for preventing molten metal from leaking outside, prevent the interface when each part is connected from not closing and causing molten metal to leak outside, mould is caused to damage, the sprue bush is reasonable in design, low cost, is adapted to widely promote the use of.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is mounting structure schematic diagram of the invention；
Fig. 3 is foam ceramic filter structural representation of the invention.
Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Fig. 1 is referred to, the present invention provides a kind of technical scheme：A kind of improved low pressure casting die sprue bush,Including sprue bush main body 1,Projection 2,Foam ceramic filter 3,Insulation material 4,Square fixed block 5,Cast passage 6,The outer wall of sprue bush main body 1 is stainless steel structure,Inwall is ceramic structure and foam ceramic filter 3 and the ceramic structure of inwall is formed in one structure,The sprue bush main body 1 is fixed on the middle part of fixed structure 8 by square fixed block 5,The top of sprue bush main body 1 is connected by projection 2 with the sprue gate of bed die 7,Projection 2 can prevent molten metal side leakage,Leave the cast structure of passage 6 in the middle part of the sprue bush main body 1,The cast passage 6 is two intersecting trapezoidal shape structures,And top and bottom are respectively kept with projection 2 and the structure of rectangle concave block 9,The middle part of cast passage 6 and top are mounted on foam ceramic filter 3,The outside of cast passage 6 is filled with insulation material 4,Preventing body of casting molten metal during the cooling can not carry out feeding in being set in sprue bush to the body of casting,Cast passage 6 bottom is connected by the structure of rectangle concave block 9 with stalk 10,The foam ceramic filter 3 is provided with mesh 31,The mesh 31 is rounding wimble structure.
During work, molten metal is entered in die cavity by pouring into a mould passage 6, middle setting has the structure of twice foam ceramic filter 3, one, it is ensured that molten metal is entered in die cavity with certain even pace, there is good cushioning effect to molten metal, two, molten metal often has slag inclusion and is mingled with, and the foam ceramic filter 3 can be filtered effectively to it, ensure that molten metal can be filtered well when entering in die cavity, improve the qualification rate of the body of casting.
It is obvious to a person skilled in the art that the invention is not restricted to the details of above-mentioned one exemplary embodiment, and without departing from the spirit or essential characteristics of the present invention, can in other specific forms realize the present invention.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, the scope of the present invention is limited by appended claims rather than described above, it is intended that all changes fallen in the implication and scope of the equivalency of claim are included in the present invention.Any reference in claim should not be considered as the claim involved by limitation.
In addition, it should be understood that, although the present specification is described in terms of embodiments, but not each implementation method only includes an independent technical scheme, this narrating mode of specification is only for clarity, those skilled in the art should using specification an as entirety, technical scheme in each embodiment can also through appropriately combined, formed it will be appreciated by those skilled in the art that other embodiment.
