Specific implementation mode
Embodiment
Fig. 1 is a kind of stereoscopic schematic diagram of guide wheel for excavator integrated cast structure embodiment of the utility model, and Fig. 2 is this practicality
A kind of structural schematic diagram of novel guide wheel for excavator integrated cast structure embodiment.As shown in Figure 1 and Figure 2, a kind of guide wheel for excavator
1 integrated cast structure, including guide wheel 1, sprue 3, cross gate 6, ingate 7 and riser.The upper end of sprue 3 is provided with sprue cup
2, the shape of sprue cup 2 is infundibulate, is conducive to molten metal and flows into sprue 3.The lower end of sprue 3 by cross gate 6 with
Ingate 7 is connected, and sprue 3 is vertical with cross gate 6.The bottom of sprue 3 is provided with well 8, and cross gate 6 is located at cast gate
The top of nest 8, well 8 there is cushioning effect, mitigation to be rushed to 3 bottom casting mold of sprue the metal liquid stream in sprue 3
Brush；The pressure distribution in cross gate 6 can also be improved, mitigate the turbulence level of liquid stream in cross gate 6, mitigate the oxygen of molten metal
Change, hinder slag and volume gas phenomenon.Ceramic tube is provided in sprue 3, ceramic tube docile can prevent on the sand wall of sprue 3
