In recent years, Japan and South Korea ’s cars have attacked in the world market. The old European and American auto giants have retreated, the global competition in the automotive mold market has intensified, and the development of new cars has become the focus of the market. However, due to high cost, insufficient human resources, lack of investment enthusiasm, etc., they have sounded. The shutdown of European and American car mold companies has become the mainstream of the industry. At the same time, with the continuous heat heating in the Chinese automobile market, China's automotive mold companies have developed rapidly, but the key factor that mainly hinders and affects this process is the quality of the mold. Most mold companies in China have not yet done well. In the international standards in terms of marketing, standards, materials, craftsmanship, and services. Automotive molds are also a rapid development industry in China. Therefore, there is also a gap in management, technology, equipment, and human resources in different enterprises, causing users to be confused. On the whole Recognition and trust. As for a single -piece production product such as molds, users' trust and supplier's understanding of user needs are the most important, which requires a longer running -in period. The quality of the quality can only be understood by the quality, which is a continuous cycle. Only by entering this process first and entering a virtuous circle can China's automotive molds move towards the world quickly, and can occupy a leading position for a long time.

1. Who moved the cheese of mold processing quality?

Mr. Wang Zhengxiong: In the process of mold manufacturing, there are many factors that affect the quality of the mold. I think mold design, mold processing, mold assembly and debugging are the key factor affecting the final quality of the mold.

Mold design is the most critical link to determine the congenital quality of the mold. The stamping process design and the quality of the structural design directly determine the quality of the mold and the quality of the stamping parts. Designers must not only consider meeting customer requirements, but also consider the processability, reliability, maintenance of maintenance, and the convenience, safety, and life of mold use.

The mold processing process is also an important part of ensuring the quality of the mold. The processing methods and processing accuracy in the mold manufacturing process will affect the service life of the mold. The processing accuracy of each component of the mold directly affects the overall assembly quality of the mold. In addition to the impact of the equipment's own accuracy, it is necessary to improve the technical level of mold fitter, adjustment workers in the process of grinding, and debugging by improving the processing methods of parts. Improve the quality and assembly quality of mold processing, so that their mold performance, quality, and reliability meets customer production requirements.

It should be said that these ten links are the core process of mold development, and they have a great impact on the final quality of the mold. The first four links are the design technology link of the mold. The design of the stamping process is very important; the DL map design is the arrangement and planning of the stamping process design; the digital model re -design is the analysis and compensation of the defect prediction after the stamping of the product; the structural design design; the structural design It is a scientific, reasonable, and economic structure to achieve stamping process design, and reflects the operating, maintenance and manufacturing of the mold. Therefore, the design technology of the first four links determines the final quality of the mold of more than 85%. This is why the major mold factories in recent years have been making strong technology teams, and some private enterprises have also established their own mold development technology teams.

The latter six links are basically a processing technology link. In these processes, more and more application preparing programs are increasingly processed by driving machine tools. There are two major characteristics of processing here: First, the degree of manufacturing and processing application CNC machine tools is increasingly popular, and processing is increasingly intelligent. In the last six links, there are two most important aspects: one is the processing accuracy; the second is the debugging level.

High -level processing accuracy is by no means simply skilled operation, which contains a lot of process skills. In other words, high -precision machine tools may not be able to process high -precision products because it lacks process; low -precision machine tools can also process high -precision products because it masters process skills. Therefore, if you want to improve the processing accuracy of CNC machine tools, the key is to improve the level of processing technology and the implementation rate of process.

Debugging is the verification and confirmation of design technology and processing accuracy, and at the same time, it must have the ability to solve the solution of comprehensive analysis and processing, and realize the unrealized design intentions by debugging. Therefore, it can be said that the key link that affects the final quality during the manufacturing process is processing accuracy and debugging level.
