Specific implementation mode
Embodiment
Fig. 1 is a kind of structural schematic diagram of the integrated cast structure embodiment of excavator driving wheel of the utility model.Such as Fig. 1 institutes
Show, a kind of integrated cast structure of excavator driving wheel, including sprue cup 1, sprue 2, cross gate 6 and ingate 8.Sprue cup 1
Shape be infundibulate, be conducive to molten metal flow into sprue 2 in.Sprue cup 1 is connected by sprue 2 with cross gate 6, directly
Running channel 2 is mutually perpendicular to cross gate 6.The top of sprue 2 is connected to sprue cup 1, and the lower part of sprue 2 is provided with well 5,
Cross gate 6 is arranged in the top of well 5.Well 5 has cushioning effect to the metal liquid stream in sprue 2, mitigates to straight
2 bottom casting mold of running channel washes away；The pressure distribution in cross gate 6 can also be improved, mitigate the turbulent journey of liquid stream in cross gate 6
Degree mitigates oxidation, resistance slag and the volume gas phenomenon of molten metal.Sprue 2 is internally provided with ceramic tube, and ceramic tube docile is directly being poured
On the sand wall in road 2, prevent the molding sand in sprue 2 from being washed away to be mixed in molten metal by molten metal and enter cavity, pollution gold
Belong to liquid.
One end of cross gate 6 is connected with sprue 2, and the other end is connected with ingate 8, and ingate 8 and cross gate 6 are flat
Row.One end that cross gate 6 connects ingate 8 is provided with slag trap 9.The other end of ingate 8 is connected with disc side periphery, and
