Arc-shaped thin-wall anti-deformation die-casting die core

The utility model relates to an arc-shaped thin-wall anti-deformation die-casting die core which comprises an upper die core, a lower die core and an arc-shaped butt joint face, the upper die core and the lower die core are arranged in a stacked mode, the arc-shaped butt joint face is adopted in the middle of the butt joint face of the upper die core and the lower die core, and die cavity shallow grooves are symmetrically formed in the middle of the lower die core. Two main runners which are in butt joint with the rear end of the mold cavity shallow groove are symmetrically arranged at the rear part of the upper end surface of the lower mold core, inlet inner grooves with gradually increased opening sections are formed in the front ends of the main runners, and first strip-shaped shallow grooves and second strip-shaped shallow grooves are formed in the rear part and the front part of the mold cavity shallow groove. The die has the characteristics that the structure is simple, the adhesive force between the lo
