[0026] The two secondary gating assemblies 30 each include a secondary sprue 31 connected to the main horizontal gating 22 and passing through the middle of a molding group 10, several secondary horizontal gating 32 connected to the secondary sprue 31 and corresponding to several molding parts 11 in the molding group 10, several annular gating 33 connected to the several secondary horizontal gating 32, and several inner gating 34 connecting the several molding parts 11 and the several annular gating 33 in the molding group 10. Specifically, the secondary sprue 31 and the secondary horizontal gating 32 in this application are arranged in a cross shape, so that the annular gating 33 can achieve a better connection with the secondary sprue 31.

[0027] In practice, molten iron is poured into the main sprue 21 and flows sequentially through two secondary sprues 31, several secondary sprues 32, several annular sprues 33 and several ingates 34 to several molding sections 11 to form the casting blank.

[0028] In this embodiment, both molding groups 10 of this application include five stacked molding parts 11. In this way, the two molding groups 10 can form ten casting blanks at a time, which improves work efficiency and sand-to-iron ratio compared with the molding method in the prior art.
