The invention relates to an automotive air intake grating plate die, which comprises an upper die and a lower die, wherein the upper and lower dies are provided with an upper die core and a lower die core for molding a circular arc products respectively; and the upper and lower die cores are provided with an upper die core circular arc surface and a lower die core circular arc surface for molding the products respectively. The vehicle air intake grating plate die is also provided with an exhaust system used for exhausting the air generated in the production of the die out of the die and a water transporting system for cooling the die. The exhaust system is water transporting inclined holes arranged in the upper and lower die cores respectively and comprises a top pinhole used for exhausting and vent holes arranged on bulges of the die cores. The structure reduces the bores of the water transporting hole, but has the same water transporting effect. Because the number of the bores is reduced, the die has a rela
