Embodiment
As shown in Fig. 1 to 2, a kind of new device for sand coated iron mould casting device using exothermic riser, for being cast to thin-walled hub
The casting of part, including mo(u)ld top half sandbox 1 and mo(u)ld bottom half sandbox 2；
Cylinder casting lower mold cavity 3 is provided with the mo(u)ld bottom half sandbox 2, casting main body is located at the casting of the mo(u)ld bottom half sandbox 2
Make in lower mold cavity 3；The bottom of the casting lower mold cavity 3 is uniformly provided with three lower exothermic risers 4, lower exothermic riser 4 and casting
Lower mold cavity 3 is made to connect；Because the bottom boss of thin-walled hub casting is thermojunction position, the flange thickness being attached thereto is relatively thin,
Cooling is very fast, it is impossible to plays feeding effect, the lower exothermic riser 4 of setting plays a part of forcing feeding；The mo(u)ld bottom half sandbox 2
The casting upper end surrounding of lower mold cavity 3 is uniformly provided with multiple card convexs 5, and described card convex 5 is used to be connected with described mo(u)ld top half sandbox 1.
The lower end of the mo(u)ld top half sandbox 1 is provided with the upper mould 6 of casting, and when in use, mould 6 is located at mould under described casting in casting
In cavity 3, mould 6 and casting lower mold cavity 3 are correspondingly arranged in described casting；The upper end of mould 6 is surrounded by card in the casting
Groove, described neck are correspondingly arranged with the card convex 5 on mo(u)ld bottom half sandbox 2；It is described when mo(u)ld top half sandbox 1 is connected with mo(u)ld bottom half sandbox 2
Card convex 5 is located in described neck；
Running gate system is set in the mo(u)ld bottom half sandbox 2, and casting system includes sprue 7 and circular cross-runner 8, and annular is horizontal to be poured
Road 8 is located at the lower section of sprue 7 and connected with sprue 7；The ingate 9 connected with circular cross-runner 8 is located at the lower molding sand
The bottom of the body of case 2 and casting lower mold cavity 3, i.e., positioned at the cylindrical place in casting wheel side, and face parallel with casting bottom boss；Institute
Mo(u)ld top half sandbox 1 is stated to connect with described casting lower mold cavity 3 provided with venthole 10；
Described mo(u)ld top half sandbox 1 is provided with upper exothermic riser 11, and described upper exothermic riser 11 is located at the wheel of casting upper end
At side, and away from described ingate 9；Because in casting process, when poring rate is slightly slow, iron liquid is injected slow by bottom
Rise, it is slower to fill type, and molten iron cooling is fast several times, and cold shut easily occurs in wheel side edge；Described upper exothermic riser 11 can prevent from taking turns
The cold shut phenomenon of cincture edge.
The utility model solves the interior feeding problem of boss thermal center in thin-section casting, eliminates such engineering machinery casting
The defects of, the casting quality of raising, add economic benefit；The utility model is highly suitable for the wheel rim casting of non-complex profile
Part, it is simple to operate easily to implement.To promote promoting the use of for device for sand coated iron mould technique to provide new approaches
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
It is not new to this practicality although above-mentioned specific embodiment of the present utility model is described with reference to accompanying drawing
The limitation of type protection domain, on the basis of technical solutions of the utility model, those skilled in the art need not pay creativeness
The various modifications that can make of work or deformation still in the scope of protection of the utility model.
