The utility model discloses an automobile covering part stamping die which comprises an upper die and a lower die. A male die and an edge pressing ring are arranged between the upper die and the lower die. The profile size of the upper die, the profile size of the male die and the profile size of the edge pressing ring are respectively larger than the stamping sizes of the corresponding faces of a covering part to be stamped. According to the automobile covering part stamping die, under the condition that the casting shrinking rate directly influencing the size accuracy and the position degree of a casting is considered, the shrinking rate of the profile of the die is amplified to a certain degree, so that the profile size of the upper die, the profile size of the male die and the profile size of the edge pressing ring are respectively larger than the stamping sizes of the corresponding faces of the covering part to be stamped, the casting shrinking rate shortages of a plate and the die are overcome, and the
