With the development of information technology and computer network technology, manufacturing industry has entered a new era of global competition. As one of the important basic industries of modern manufacturing industry, mold manufacturing industry is widely used in production. Almost all hardware, plastic and rubber products need to be processed by mold. As the efficiency of mold design and manufacturing has a decisive impact on the product development efficiency, in order to meet the needs of global competition, mold enterprises must move from decentralization to cooperation. Mold design units, manufacturing enterprises and mold users must carry out full cooperation and communication, and make use of networked collaborative technology to give full play to their respective technical advantages, In order to quickly develop high-quality mold products.

Development status of mold collaborative technology: Computer Supported Cooperative Work (CSCW) was first proposed by Irene Greif of MIT and Paul Cashman of Dec in 1984. It refers to a group working together to complete a common task (CW) in the environment of computer technology support (CS). Its goal is to design a variety of cooperative application systems. It includes the construction of collaborative work system, the research of group work mode, the research of related technologies to support group work, the development of application system and so on. In recent years, a lot of research has been done on the mold collaborative design and manufacturing platform at home and abroad. A large number of scholars are doing the research of mold networked collaborative platform, and have achieved some results. However, because some key technical links have not been solved, some of the so-called "collaboration" being implemented are simply some negotiations through e-mail, and some are only the collaboration used within a single enterprise. These can not be called networked collaboration in a complete sense. In order to realize effective networked collaborative design and manufacturing in mold product development, we still need to do a lot of research and development work.

Development direction of mold collaborative technology: networked collaborative design and manufacturing is the main production mode of manufacturing industry in the 21st century. It effectively improves the resource utilization of the industry, strengthens the cooperation between enterprises, and greatly improves the production efficiency. With the continuous progress of science and technology, the manufacturing industry is developing in the direction of digitization, intelligence, networking and globalization. The product life cycle is shorter and shorter, and the listing speed of new products is faster and faster. At present, computer technology has been widely used in the processing and manufacturing industry. Some mold manufacturing enterprises in China are gradually using CAD / CAPP / CAE / CAM and other advanced technologies for mold development, and have achieved certain results. But generally speaking, there is still a big gap between China's mold development technology and market requirements. Therefore, establishing an industrial collaborative design and manufacturing platform, fully revitalizing the resource cooperation in the industry and optimizing the design and manufacturing process will play a great role in improving the overall competitiveness of the industry. The industry oriented mold networked collaborative platform improves the innovation ability, flexibility and adaptability of industry products by integrating industry manufacturing information and resources, including industry networked collaborative service platforms such as mold networked collaborative development, networked material supply, networked production and manufacturing, networked equipment, technology, talent resources, development tools and management software sharing The ability to resist risks and the overall competitiveness of the industry.

The functional modules of the industry oriented mold networked collaboration platform mainly include public resources, market information resources and collaboration platform. The market information part realizes a complete supply chain, and registered enterprises can publish purchase and supply information. If an enterprise needs outsourcing, it can also carry out bidding and bidding. Collaborative work is the most critical part of the collaborative platform. After establishing a collaborative relationship, enterprises can apply the functions of the collaborative work platform, from project creation to task decomposition, to collaboration and adjustment, to the final logout, and can communicate at any time through the collaborative method provided by the platform. The networked collaborative development model requires the personnel of multiple departments of different enterprises to execute each sub task of the project at different locations at the same time. In order to support group collaborative work, an integrated collaborative project management system must be established. The collaborative project management system is based on the web network, and the project managers and collaborative working groups share resources (data, documents, design tools, etc.) under the control of certain permissions.
