CNC punch die is a technology intensive and capital intensive product, which plays an important role in China's national economy. Mold industry has been officially identified as the basic industry in China, and listed as a key support industry in the "Tenth Five Year Plan". Due to the continuous development of new technology, new material and new technology, mold technology is constantly improving, and the requirements of knowledge, ability and quality of talents are also constantly improved.
With the development of modern science and technology, it is more and more important for the development of modern science and technology, such as the integration of modern science and technology, science and technology of science and technology. The development trend of die and mold technology is that the mold products are developing in the following directions:
(1) High precision
The precision requirement of modern mould is at least one order of magnitude higher than that of traditional mould
(2) Long life
The life of modern mould is 5-10 times longer than that of traditional mould. For example, modern molds can reach more than 5 million times, and the increase can reach 600 million times.
(3) High productivity
Due to the use of multi position progressive die, multi energy die, multi cavity injection mold and laminated injection mold, the productivity can be greatly improved, thus bringing significant economic benefits. If the injection mold with four stations is used to produce plastic water bottles, more than 8000 pieces can be produced per hour.
(4) Complex structure
With the diversification and individuation of social needs and the wide application of many new materials and new technologies. The requirements for the structure and cavity of modern mold are also increasingly complex. If the traditional mold manufacturing method is used, not only the cost is high, the productivity is low, but also it is difficult to ensure the quality requirements of the mold.
The traditional mold design and manufacturing technology can not meet the requirements of the market. Therefore, it is imperative to develop new die design and manufacturing technology. Die CAD / CAM and RT technology are developed in this situation, and play an important role in modern mold production.
Therefore, the technical content of mold products is constantly improved, the mold manufacturing cycle is constantly shortened, the mold production is developing towards the direction of informatization, no drawing, refinement and automation, and the mold enterprise is developing towards the direction of technology integration, equipment refinement, production batch branding, management informatization and operation internationalization. Based on this, the reasonable design of mold has a very important and far-reaching significance.
