The invention relates to a preparation method for a metal ceramic die. The preparation method comprises the following steps: uniformly mixing tungsten powder, nickel powder, aluminum carbide, siliconcarbide, titanium dioxide, zirconium dioxide, a reinforcing agent, polyurethane and potassium borohydride in a ratio, placing the raw materials in a ball mill and milling the raw materials into a mixed powder with a particle size of 300 meshes, and then conveying the mixed material into a smelting furnace; smelting at a temperature of 1800-1900 DEG C to form a melted liquid, insulating heat for 1h, and cooling to reach 1300-1400 DEG C; pouring the cooled melted liquid, and then carrying out vacuum hot-pressing sintering at a temperature of 1500-1550 DEG C and under a pressure of 20-30MPa to obtain the needed die. The method disclosed by the invention is simple to operate and easy to realize; and the obtained die is more excellent and stable in performance, high in toughness, heat stabilityand abrasion resistance, and excellent in performance, and meets the use requirements.
