A shape tending heating cooling die comprises a concave die. A cavity is formed in the concave die. The bottom of the concave die is provided with an additional block insertion groove. An upper groove is machined in the top of the additional block insertion groove. Forming of the upper groove is consistent with the contour line of the bottom of the cavity. A waterway additional block is inserted into the additional block insertion groove. The shape of the waterway additional block is consistent with that of the insertion groove in the bottom of the concave die. The space between the waterway additional block and the additional block insertion groove is filled with heat-resisting spray seal materials. A lower groove is formed in the top of the waterway additional block. The lower groove and the upper groove are matched to form a waterway. The waterway penetrates through the concave die. A water inlet and a water outlet are formed in the positions, on the side wall of the concave die, of the two ends of the waterway. All matched faces of the waterway additional block and the additional block insertion groove are inclined inwards, and the inclined angles are 85-88 degrees. A compressing block is arranged under the concave die, is fixed to the concave die through a bolt and abuts against the waterway additional block, so that the waterway additional block is fixed.
