The development of mould technology should be adapted to mould products "short delivery time", "high precision", "good quality", "low price " requirements of the service.
(1) Comprehensive promotion of CAD/CAM/CAE technology
Mold CAD/CAM/CAE technology is the development direction of mold design and manufacturing. With the development and progress of microcomputer software, the conditions for the popularization of CAD/CAM/CAE technology have been basically mature, the enterprises will increase the efforts of CAD/CAM technology training and technical services; further expand the scope of application of CAE technology. The development of computers and networks is making it possible to promote CAD/CAM/CAE technology across regions, enterprises and institutes in the whole industry, to achieve the re-integration of technical resources and to make virtual manufacturing possible.
(2) High-speed milling processing
Foreign development of high-speed milling processing, a substantial increase in processing efficiency, and can obtain a very high degree of surface finish. In addition, high hardness modules can also be processed, but also has the advantages of low temperature rise and small thermal deformation. The development of high speed milling technology has injected new vitality into the manufacture of large cavity moulds in the automotive and appliance industries. It has developed towards greater agility, intelligence and integration.
(3) Mould scanning and digitising systems
High-speed scanning machine and mould scanning system provides from the model or physical scan to process the desired model required for many functions, greatly shortened the mold in the development of manufacturing cycle. Some rapid scanning systems can be quickly installed on existing CNC milling machines and machining centres to achieve rapid data acquisition, automatically generate a variety of different CNC system processing procedures, different formats of CAD data for the mould manufacturing industry, "reverse engineering". Mold scanning system has been in the automotive, motorbike, home appliances and other industries have been successfully applied, I believe that in the "Tenth Five-Year" period will play a greater role.
(4) EDM milling
EDM milling technology is also known as EDM into the processing technology, which is an alternative to the traditional molding electrode processing cavity of the new technology, it is a high-speed rotation of a simple tubular electrode for three-dimensional or two-dimensional profile processing (like CNC milling), so no longer need to create complex molding electrodes, which is obviously a major development in the field of EDM forming. This is obviously a major development in the field of EDM. Foreign countries have already used this technology for machine tools in mould processing. It is expected that this technology will be developed.
(5) Improve the degree of standardization of moulds
China's mold standardization degree is improving, it is estimated that China's mold standard parts use coverage rate has reached about 30%. Foreign developed countries are generally about 80%.
(6)High quality materials and advanced surface treatment technology
The selection of high-quality steel and the application of the corresponding surface treatment technology to improve the life of the mold becomes very necessary. Mold heat treatment and surface treatment can give full play to the key aspects of mold steel material performance. The development direction of mould heat treatment is the use of vacuum heat treatment. Die surface treatment in addition to perfection should be developed in the process of advanced vapor deposition (TiN, TiC, etc.), plasma spraying and other technologies.
(7) mold grinding and polishing will be automated, intelligent
Mold surface quality on the mold life, the appearance of the quality of the parts have a greater impact, research automation, intelligent grinding and polishing methods to replace the existing manual operation, in order to improve the quality of the mold surface is an important development trend.
(8) the development of automatic mould processing system
This is the long-term development of our country's goal. Mould automatic processing system should have a reasonable combination of multiple machine tools; with accompanying positioning fixture or positioning plate; with complete machine tools, tools CNC library; with a complete CNC flexible synchronization system; with quality monitoring control system.
