Abstract: In view of the changing requirements of the processing tasks of traditional mold enterprises, more personalized mold processing tasks have been proposed. There is a lack of communication and cooperation between enterprises in different regions. Traditional mold enterprises only rely on their own processing resources, which is difficult to meet the needs of complex and changeable processing tasks. Introduction of cloud manufacturing model, classification and encoding rules of mold processing the task as well as the relationship between tasks, establishing the model of mold manufacturing enterprise order project using UML modeling technology, to formal description of mold processing task, determine the mold processing task constraint relations, and put forward the mold processing tasks and manufacturing resource service matching three models, And the gold, silver and copper manufacturing resources service retrieval algorithm, combined with the analytic hierarchy process, expert evaluation method and entropy weight coefficient method of subjective and objective comprehensive method to calculate the optimal index weight coefficient, the results obtained as the optimal service. The results show that it can effectively promote the cooperative work among enterprises, enrich the production and manufacturing mode of enterprises, effectively improve the utilization rate of idle processing resources, and reduce the production cost.
