[0012] Such as figure 1 , figure 2 , image 3 As shown, the upper end of the hub center is connected to a riser 2 through a riser neck 5. The riser neck 5 is an inverted cone. The lower end of the riser 2 is provided with heat-affected blocks 4a, 4b, 4c, and the center of the hub and the outer ring 1, corresponding to the position of the spoke 3, a sand core 6 is provided on one side of the hub to reduce the size of the riser neck 5 and form heat-affected blocks 4a, 4b, 4c. The arrangement of the sand core 6 can reduce the risk The size of the neck 5 can be removed with a hand hammer, which solves the trouble of using a lathe to remove and greatly reduces production costs; setting heat-affected blocks 4a, 4b, 4c at the spoke 3 can delay the solidification of the connected spokes later than The solidification time of the connection between the outer ring and the spoke plate ensures that the quality of the outer ring is qualified; when working, the molten iron first enters the r...
