The application discloses a high-thermal-conductivity and high-hardness plastic mold steel and a preparation method thereof. In view of the low thermal conductivity, insufficient hardness and poor wear resistance of the existing plastic mold steel, the application realizes the optimization of the comprehensive performance of the material by directional modification of nano silicon nitride, titanium alloy powder and graphene, in combination with a specific component proportion and a preparation process. The mold steel is composed of a 42CrMo steel base body, modified nano silicon nitride, modified titanium alloy powder, modified graphene and alloy elements such as vanadium iron and niobium iron. The preparation process comprises the steps of batching, mixing, vacuum induction smelting, forging, heat treatment and finishing. Through the synergistic effect of the modified material and the alloy elements, the hardness of the mold steel reaches 62-65HRC, the thermal conductivity is 48-55W / (mK), the tensile strength is 1250-1300MPa, the impact toughness is 25-28J / cm 2 , and the wear loss is 6.8-8.5mg, the interface compatibility of the reinforced phase and the base body is improved, and the balance among the thermal conductivity, the hardness, the toughness and the wear resistance is realized.
