The utility model belongs to the technical field of mold cooling, and particularly relates to a cooling device of a circular lampshade injection mold, which comprises an upper mold and a lower mold, cavities are respectively arranged on the surfaces of the upper mold and the lower mold, a sprue gate is arranged at the top of the upper mold, a plurality of electric telescopic rods are fixedly connected to the top of the upper mold, and the electric telescopic rods are fixedly connected to the top of the lower mold. The driving end of the electric telescopic rod penetrates through the upper mold and is fixedly connected with the lower mold, and the bottom of the lower mold is fixedly connected with a cooling chamber containing cooling liquid. Impulsive force generated by backflow of cooling water pushes the blades to rotate, then the arc-shaped pipe rotates to cool the bottom wall of the lower die, compared with the prior art, the cooling effect on the die is improved, cooling dead corners are avoided, and unev
