After the development of the "Eleventh Five-Year Plan", China's mold industry has indeed made great progress. It has now entered the forefront of the world in total production. Although China is already a major producer of molds and machine tools, it is far from being a production power. This is an indisputable fact. In addition to all other necessary conditions, the development of the mold industry is critical to the improvement and advancement of equipment. Mainly manifested in: the vigorous development of foreign-funded enterprises, which has made China's mold production scale and product level have a rapid development; non-state-owned economy has sprung up, making China's mold production scale expand rapidly, and product levels are also relatively high. Improve quickly. In the Pearl River Delta and Yangtze River Delta regions where Hong Kong, Taiwanese and foreign capital are particularly concentrated, with the rise of machinery, electronics, light industry, building materials, communications and office equipment, the production of self-produced molds for internal enterprises is also used. A lot of development followed. The production scale of this part of the mold is about 30 to 50 billion yuan. The total scale of mold production in the country has exceeded 60 billion yuan in 2005. If the average input-output ratio of fixed assets is roughly 1:1, and about 60% of the investment is used to purchase new equipment, the average annual amount will be about 9 billion yuan for the purchase. Kind of equipment. This is an estimate of the equipment market in the mold industry. Although this equipment market only accounts for a small proportion of the total size of the machine tool industry, it cannot be said to be small and should not be ignored. Even if the foreign-funded enterprises are mainly used to remove foreign equipment, the domestic machine tool industry will at least have a equipment market of about 6 billion yuan per year. If domestic equipment levels and services are competitive, foreign-invested companies are also willing to purchase cheap domestic equipment. Therefore, during the "Eleventh Five-Year Plan" period, the market of about 30 billion yuan is not overemphasized by the word "huge". Competitive analysis of domestic mold equipment At present, domestic equipment produced by the domestic machine tool industry, except for a few high-end equipment, lacks independent innovation capability in China, and it is difficult to meet it at present. Most of the domestic technology and capabilities can be met, but the machine tool industry has not paid attention to it. This market in the mold industry and the lack of careful analysis of some special requirements for mold processing. [1][2][3]The main performances of the next page are: 1. The product has not been developed for the special requirements of the mold industry, and the main structure cannot be well adapted to the mold processing, including the size of the table and the load bearing, the rigidity and stability of the machine tool. Reliability, long-term full-load operation reliability, high-speed, high-efficiency and high-precision, and large-volume space surface processing; 2. Many parts and accessories on the equipment are of poor quality, especially for some electronic components and some machinery. Parts and CNC systems; 3. Due to enterprise system, mechanism and management reasons, including assembly quality and low level of comprehensive services, especially after-sales service can not keep up, so that mold companies are afraid to choose domestic equipment. As far as the mold industry equipment market is concerned, compared with imported equipment, domestic equipment is not competitive in terms of performance, reliability, accuracy, quality, delivery time and comprehensive service capability. The reasons are: first, the ability of independent innovation is weak, second, it does not pay attention to the equipment market in the mold industry, and third, the system, mechanism and management cannot keep up. Taking CNC machine tools as an example, in 2005, the output of CNC machine tools in China has exceeded 60,000 units, and the quantity and product level have made great progress, but its domestic market share is less than 30% (there is information that 2004 is 26.9%) In the mold industry, I am afraid that 20% will not be able to. Why is this? I think there are three reasons for this: First, there is a strong demand for CNC machine tools in the domestic market, especially for medium and low-end products, which are large and easy to produce. Most machine tool factories are full of tasks, which makes many related companies No longer pursue high, fine, pointed and difficult varieties and high-end products; second, most of the machine tool enterprises have weak independent innovation ability, and the core technology and key technologies are less mastered, even if they are interested in developing medium and high-end products, Although the mold industry has a relatively large equipment market, but due to the special nature of mold processing, especially the individualized requirements are more prominent, the mold enterprises are mostly small and medium enterprises, the ordering of CNC equipment is difficult to form. Larger batches, so to meet the needs of the mold industry, it is indeed more difficult, you must make great efforts, and there will be some risks, but also have a level. In view of these three reasons, domestic machine tool manufacturers still do not pay much attention to the equipment market of the mold industry or have no time to take care of them, so they have to let the imported equipment to play the leading role. The basic requirements of the mold industry for equipment Compared with other mechanical processing, mold processing has its own particularity. These specialities are mainly: 1. Most molds need to process complex curved surfaces on solid metal modules. As the mold continues to develop to large-scale, the weight of the module will also become larger and larger, and now some have reached several tens of tons; 2. Most of the molds are cuboid or cube, rarely narrow and long, the main processing volume is concentrated in Die and punch; 3. As the requirements of mold products become more and more precise and complex, the requirements for mold processing accuracy are getting higher and higher. Now the machining accuracy of many molds has reached ±1~2μm, and will soon be soon. The development is less than ±1μm; 4. As the user's requirements for the mold production cycle become shorter and shorter, the mold processing must meet the requirements of high efficiency, fastness, certain flexibility and long-term full load without stopping. According to the above four special characteristics, the following basic requirements are imposed on the mold processing equipment: 1. The machine tool should have good rigidity and large bearing capacity corresponding to the weight of the module; 2. The size of the work surface should be adapted to the mold size. It should be rectangular or square and round, not narrow and long, but the height direction and its stroke require a large space; 3. It must have high precision and precision retention; 4. To quickly and efficiently remove the allowance, And has high reliability to maintain continuous long-term full load operation; 5. In order to adapt to complex space surface processing, and a large amount of processing, it is required to have multi-axis linkage of machine tools, and CNC system with large information capacity . The above only puts forward some basic requirements for most mold processing equipment, in addition to many special requirements. For example, machine tools for processing plastics require higher speeds, but because of the small cutting force, the machine tool can be light-weighted because of the low cutting cost; the grinding press for trial molds is not required to be efficient and fast, but requires reverse rotation energy. In order to repair the mold; a large number of repetitive processing of some simple processes can be used for special planes and so on. At the same time, composite processing, flexible processing and on-line inspection are also requirements for mold processing.
