The invention discloses a moulding punching device for automobile tail light die production. The moulding punching device comprises a hydraulic disc, a punching disc, a drawing and pulling rod, a draught fan, a dust extraction disc, a working table, a preheating bin, a containing disc, a grabbing support, buffer spring rings, a supporting frame, a heating ring groove, a grabbing hook, a movement spring, a connecting column, a damping ring, a dust filtering disc, a first overturning shaft, a dust storing receiving disc and a second overturning shaft. The moulding punching device has the beneficial effects that the moulding punching device conducts punching moulding on the working table, before punching moulding, a tail light die is clamped through the grabbing support, the die is driven by the containing disc to move downwards, the die is preheated through the heating ring groove in the heating bin, and therefore the die is easily moulded and punched, punching is more efficient, and the using flexibility is guaranteed; the multiple buffer spring rings are arranged below the working table, when the die is punched through the punching disc, high buffer force can be provided for the die through the buffer spring rings, and the high punching quality is guaranteed; and the device is convenient to operate, and connection of all components is flexible.
