Summary:The invention relates to an anti-cracking core bar assembly of a cantilever sand core, which comprises a first core bar, a plurality of second core bars and a plurality of third core bars, the first core bar is arranged at the cantilever of the cantilever sand core, the plurality of second core bars are arranged at the non-cantilever of the cantilever sand core, and the first core bar and the second core bars are connected through the plurality of third core bars; and the second core bar is provided with an implanting part, and the implanting part is exposed out of the cantilever sand core and is implanted into a casting in the pouring process. According to the anti-cracking core bar assembly of the cantilever sand core, the second core bar is implanted into the casting and matched with the first core bar and the third core bar to form a closed-loop whole, the strength of the whole sand core is enhanced, particularly, the cantilever position is protected, and the casting quality is improved; the anti-cracking
