The invention discloses a machining die for automotive shock pads. The die comprises guide wheels, a base, a level gauge, fixing claws, LED lamps, a heat dissipation controller, a cooling fan, a shock pad support die, hydraulic rods, heaters, a thermometer and a pressure sensor; the guide wheels are arranged on side walls of the base; the level gauge is arranged on the base; connecting pieces are arranged on two sides of the base; telescopic rods are arranged on the connecting pieces; and the fixing claws are arranged at bottom ends of the telescopic rods. The die is moved conveniently by the aid of the guide wheels in a time-saving and effort-saving manner, the base is arranged horizontally and conveniently by the aid of the level gauge, the condition that the quality of the shock pads is affected due to the non-level state during stamping is avoided, the purpose of intelligent heat dissipation is further achieved, the condition that the stamping effect is affected due to sliding caused by the excessively large impact power is avoided through adjustment and auxiliary fixing by the aid of the fixing claws and the telescopic rods, illumination is realized by the aid of the LED lamp at night or when the light is relatively dark, and working and maintenance by a worker are facilitated.
