The utility model discloses a special-shaped ceramic radiator mould. A first slurry inlet (1) and a second slurry inlet (2) are formed in the special-shaped ceramic radiator mould, the first slurry inlet (1) and the second slurry inlet (2) are arranged symmetrically and have the identical shapes and structures. The cross sections of the opposite sides of the first slurry inlet (1) and the second slurry inlet (2) are shaped like a semicircle. The special-shaped ceramic radiator mould further comprises an internal mould (3) and an external mould (4), and the distance between the internal mould (3) and the external mould (4) in the vertical direction is 1.15 mm. Through increasing the distance of the thinnest portion between the internal mould and the external mould to 1.15 mm, the slurry can pass through the space of the thinnest portion smoothly and be filled into the other places of a product when the product is formed by hot pressing, and the yield of forming by hot pressing of such kind of products is greatly improved.
