Abstract: To research on how to apply cloud computing technology in mold industry to promote its industrialization,the problems, needs and their reasons in Chinese mold industry were analyzed. Cloud manufacturing service platform, system and key technologies of mold manufacturing industry were proposed. By using cloud computing technology, mold parts library and knowledge base construction, business collaborative integrity management, collaborative design and manufacturing as well as coordination service and information technology services were supported; mold industry cloud manufacturing service platform was researched as a social-technical system. Through establishing various forms of alliances, the successful implementation of cloud manufacturing service platform and systems was ensured;oriented to the whole value chain process of mold, helping mold companies expand their business to services industries and to upstream and downstream of mold industry. The prototype of cloud services platform for mold manufacturing industry was established, and the development vision and mode of cloud manufacturing service platform driven by mold manufacturing industry demand were given.

Key words: cloud computing, cloud manufacturing, mold manufacturing industry, parts library, knowledge network, ontology
