The mold industry is an important pillar industries of machinery manufacturing, electronic industry, light industry and other industrial sectors, currently about 60 to 80% of the products of these sectors workpiece mold forming. Plastic, rubber, ceramics, building materials and glass products, and now the majority of mold forming. The quality of the service life of the mold and manufacturing cycle with a lot of product quality, dimensional accuracy, surface roughness, and upgrading the speed and cost of the product directly. For China's mold industry, the average service life of the mold is still very low, coupled with the technology and management of long lagged behind China's mold industry in the fierce market competition tend to rely on price to win, reduce mold industry the benefits, and many large, sophisticated, complex, long-life mold, still rely heavily from abroad imports. The rapid development of the industry, making the mold production capacity, quality and management to improve long way to go. Phenomenon sticky mold mold used, mainly by the material's surface morphology, roughness, hardness, corrosion resistance and abrasion wear properties. Reduce generation sticky mode phenomenon causes the surface of the product quality, increase product cost, and reduce the life of mold negative impact. This paper by emerging specialty processing methods - electron beam surface modification technology, the surface of the mold material processing, analysis of electron beam processing parameters, coating alloys and thickness of the material surface properties to improve the surface properties of the mold material, which enhance mold release properties when used; simulate the temperature field distribution of the electron beam surface alloying temperature to determine substrate and coating material molten state. Electron beam surface treatment directly the subject of 40Cr material, electron beam surface alloying treatment 3Cr2W8V materials, as well as the pure Ti for 3Cr2W8V surface coating the surface of the electron beam with finite element software alloying temperature field numerical analysis to summarize : (1) the impact of the electron beam processing parameters on the material surface topography and organizational change; (2) material surface properties with the trend of the electron beam processing parameters; (3) electron beam surface alloying material depth temperature distribution situation. Through the study of the subject, to prove that the use of electron beam surface modification methods, general modification and surface alloying is greatly improved surface microstructure and mechanical properties of materials on the surface of the mold material, mold release performance also greatly improved.
