Pouring device for casting anti-deformation casting

The casting device comprises a protection box, a bottom plate, an upper mold and a lower mold, the upper mold and the lower mold are in a mold closing state, L-shaped plates are installed at the four corners of the bottom plate through hinges, the L-shaped plates are arranged at the four corners of the upper mold and the four corners of the lower mold respectively, the upper ends of the L-shaped plates are bent inwards to form fixing parts, and the lower ends of the L-shaped plates are connected with the protection box. Clamping mechanisms for tightly pressing the upper die and the lower die are installed on the fixing parts, the lower ends of the supporting pipes penetrate through the through holes to extend to the outside and are provided with bases, and a plurality of springs are installed between the through holes and the supporting pipes. The die is simple in structure, deformation of internal metal parts caused by direct impact on the upper die and the lower die is avoided, the four angles of the upper
