Specific implementation mode
Embodiment
Fig. 1 is a kind of structural schematic diagram of driving wheel integration mold integrated cast structure embodiment of the utility model.Such as Fig. 1 institutes
Show, a kind of driving wheel integration mold integrated cast structure, including template 1 and driving wheel mold 2.Template 1 is integrated with driving wheel mold 2
Structure, good fixing effect, template 1 and driving wheel mold 2 are placed on sand mold when being molded in sandbox and are unlikely to deform, are not easy to mould shift,
The driving wheel precision that casts out is high, high yield rate.The side of template 1 is provided with 4 handles 11, facilitate template 1 carrying and
It is mobile.It is provided with otic placode 12 between handle 11, through-hole, the mounting hole of 1 upper surface of otic placode 12 and template are provided on otic placode 12
13 all have the effect of fixed template 1 and mold.The lower surface of template 1 is provided with latticed reinforcing rib, can improve template 1
Intensity, reduce template 1 deformation.
The center of 2 internal cavities of driving wheel mold is provided with mounting base two, sprue 4 is fixedly mounted on mounting base
On two.The top of sprue 4 is provided with sprue cup 5, and the shape of sprue cup 5 is infundibulate.It is poured with horizontal the lower part of 4 side of sprue
The one end in road 3 is connected, and the other end of cross gate 3 is connected with 8 one end of ingate, and one end of the connection ingate 8 of cross gate 3 is set
It is equipped with slag trap 9.The other end of ingate 8 is connected with the side periphery of driving wheel mold 2, and justifies with 2 side of driving wheel mold
Circumferential surface it is tangential vertical.Cross gate 3 is mutually perpendicular to sprue 4, and cross gate 3 is criss-cross construction.The horizontal of such structure pours
Road 3 can make the molten metal in sprue 4 pass through 4 cross gates 3 through ingate 8 while carry out filling type to driving wheel, fill type effect
Rate is high, the mobility of molten metal is big, can reduce the formation of casting flaw.
