=Due to the increasing requirements for molds, the traditional mold making method can no longer meet the needs, which promotes the application of CAD/CAM technology in the mold industry. The CAD/CAM application software used in modern design and manufacturing technologies, such as object-oriented technology, integration technology, virtual manufacturing and Web-based collaborative design technology, and design and manufacturing as a whole, the integration of design and manufacturing information processing. China’s computer technology started late, and the development of mold CAD/CAM began in the late 1970s, but its development is also quite rapid. Mold CAD/CAM is developed on the basis of the development of mold CAD and mold CAM respectively. Application of CAD/CAM technology in injection mold: 1) Geometric shape of plastic products 2) Growth of cavity surface shape 3) Design of mold structure scheme 4) Selection of standard mold base 5) Generation of part assembly drawing and assembly drawing 6 )
Mechanical analysis 7) Generation of mold part drawings 8) Injection process conditions and injection mold material optimization 9) Injection flow and pressure holding process simulation 10) Cooling process analysis CAD/CAM technology in cold die: 1) Using geometry Modeling technology to complete complex mold geometry design 2) Completing process analysis and calculation, assisting forming process design 3) Establishing standard graphics library to improve design efficiency 4) Auxiliary to complete mold processing design and NC programming 5) Auxiliary to complete drawing work, output mold parts Figure and assembly diagram 6) Using computer to complete numerical counting such as finite element analysis and optimization design. So far, CAD/CAM systems such as precision die, ordinary blanking die, roll forging die, hammer die and injection mold have been identified by relevant state departments, which play an important role in production and produce huge economic benefits.
The main problems of China’s mold CAD/CAM technology: 1, CAD / CAM integration is not high, still stay in the application of NC programming and drawing; 2, CAD / CAM hardware and software are dependent on imports, independent copyright software is Plastic parts processing supplier very Less; 3, lack of technology and equipment strength. It provides users with an effective auxiliary tool in the form of computer software, enabling technicians to design and optimize products, mold structures, forming processes, CNC machining and costs by means of computers.What is the mold CAD/CAM?Mold CAD/CAM refers to the use of computers as the main technical means to process various information in mold design and manufacturing. It is a new leap in the comprehensive application of computer technology in mold production. Mold CAD/CAM is the key technology to transform the traditional mold production method, and it is a high-tech and high-efficiency system work.
