The side surfaces of the horizontal runner 6 are respectively connected to the input ends of the cutoff piece B7 and the input ends of the cutoff piece C9. The tail end of the cutoff piece B7 is connected to the vertical runner D11, and the tail end of the cutoff piece C9 is connected to the vertical runner C10. Both the vertical runner C10 and the vertical runner D11 are rectangular parallelepiped structures.

[0036] The middle of the vertical runner D11 is connected to the input end of the water inlet piece B13. The tail of the horizontal runner 6 is connected to the slag collecting column B8, which is a columnar structure. The middle of the vertical runner C10 is connected to the input end of the water inlet piece A12. The output end of the water inlet piece A12 is connected to the window position of the cylinder head of the casting A14.

[0040] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0041] When in use, a mold is made according to this process layout, and a sand model cavity is obtained after shaping. A filter residue sheet is placed in the filter residue structure 3. The tempered molten iron enters from the pouring cup 1 and flows into the vertical runner A2. When passing through the filter residue sheet in the filter residue structure 3, the flow rate slows down, and the filter residue sheet filters out the slag in the molten iron. Then the molten iron flows into the vertical runner B21, and the tip molten iron enters the slag collecting column A4. The tip molten iron may be mixed with sand components in the casting system, which will remain in the slag collecting column A4 at this time. The following molten iron further flows slowly through the intercepting piece A5 to avoid slag and flows into the horizontal runner 6. At this time, the tip molten iron enters the slag collecting column A4. The molten iron at the end flows into the slag collecting column B8, and the following molten iron is diverted by the cut-off piece B7 and the cut-off piece C9 on the side of the horizontal runner 6, and flows into the vertical runner C10 and the vertical runner D11 respectively. Thereafter, the molten iron successively enters the water inlet piece A12, the water inlet piece B13B, the water inlet piece C16, and the water inlet piece D18, reaches the riser 17, and flows into the casting A14 and the casting B19 through the riser neck A15 and the riser neck B20. The above is the entire filling sequence, and the filling is considered complete until the castings A14 and B19 and the entire pouring system are completely filled with molten iron. As time goes by, the temperature of the molten iron decreases, and the locations with low thermal modulus such as the water inlet plate and the cut-off plate in the casting system solidify first. The locations of the water inlet plate A12 and the water inlet plate B13 are set at the weak position in the middle of the tail. The continuous inflow of molten iron increases the thermal modulus of this location, making up for its structural deficiencies. The water inflow of riser 17 also increases the thermal modulus of riser 17 to achieve sequential solidification, meeting product quality while greatly improving the shrinkage compensation efficiency of riser 17.
