my country's mold industry has indeed made great progress. According to the analysis of mold expert Luo Baihui, the development speed of the mold industry during the "Eleventh Five-Year Plan" period is running at a high rate of more than 15% higher than the average annual rate. At present, the total scale of mold production in the country excluding Hong Kong, Macao and Taiwan has reached about 100 billion yuan. If the average annual increment of 15 billion yuan is used, the ratio of input to output of fixed assets is roughly 1:1, and about 60% of the investment is used to purchase new equipment. 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 should not be ignored. Even if foreign-funded enterprises mainly use foreign equipment, there will be at least an equipment market of about 6 billion yuan per year left for the domestic machine tool industry. Therefore, if the national machine tool industry can grasp this market, it is not an exaggeration to describe the market of about 30 billion yuan during the "Eleventh Five-Year Plan" period with the word "huge".

Basic requirements for equipment in the mold industry

Compared with other mechanical processing, mold processing has certain particularities. These particularities are mainly: 1. Most molds need to process space curved surfaces with complex shapes on solid core metal modules. With the continuous development of large-scale molds , the weight of the module will also become larger and larger, and now some have reached dozens of tons; 2. Most of the molds are rectangular or square in shape, few are narrow and long, and the main processing volume is concentrated on the die and punch; 3. As the requirements of mold products become more and more precise and complex, the requirements for mold machining accuracy are also getting higher and higher. Now the machining accuracy of many molds has reached ±1~2μm, and will soon develop to less than ±1μm; 4 .As the user's requirements for the mold production cycle are getting shorter and shorter, the mold processing must meet the requirements of high efficiency, fast, and certain flexibility and long-term full-load non-stop operation. According to the above four particularities, the following basic requirements are put forward for the mold processing equipment: 1. The machine tool must have good rigidity and a large bearing capacity suitable for the weight of the module; 2. The size of the work surface should be compatible with the external dimensions of the mold , suitable for 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. It must be able to remove the allowance quickly and efficiently, And it has high reliability to maintain continuous long-term full-load operation; 5. In order to adapt to complex spatial surface processing, and there is a large amount of processing, it is required that the machine tool can be multi-axis linkage, and equipped with a large information capacity CNC system .

The above only put forward some basic requirements for most mold processing equipment, and there are still many special requirements. For example, the machine tool for processing plastics requires higher speed, but due to the small cutting force, in order to reduce the cost, the machine tool can adopt a light structure; the research and distribution press used for mold trial does not require it to be efficient and fast, but requires reverse kinetic energy In order to repair the mold; a large number of repeated processing of some simple processes can be used with special machines, etc. At the same time, composite processing, flexible processing and online inspection are also the requirements of mold processing.

Analysis of Competitiveness of Domestic Mould Equipment

At present, the domestic equipment produced by the domestic machine tool industry, except for a few high-end equipment that lacks the ability of independent innovation in China, is difficult to meet for a while, most of the domestic technology and capabilities can be satisfied, but because the machine tool industry does not pay attention to the mold industry as a market and Due to the lack of careful analysis and research on some special requirements of mold processing. The main manifestations 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 mold processing, including the size and load-bearing of the worktable, the rigidity and stability of the machine tool, the reliability of long-term full-load operation, and high speed. High-efficiency, high-precision and large-capacity space surface processing, etc.; 2. The quality of many parts and accessories on the equipment is not up to standard, especially some electronic components, some mechanical parts and numerical control systems; 3. Due to the enterprise system , mechanism and management reasons, including assembly quality and comprehensive service level are not high, especially after-sales service can not keep up, resulting in mold companies easily dare not choose domestic equipment.
