Due to the increasing demand for injection products in industries such as automobiles, household appliances, and food, the development and improvement of injection molding technology is promoted. Among plastic processed products, 83% use injection molding, and the output of injection molding machines is increasing year by year, accounting for the largest proportion of plastic machinery.
The development trend of vertical injection molding machines can be summarized as follows:
1. The special requirements of injection molding machines are often due to different shapes of products and the price of this product.
For example, in terms of products, some of them are embedded and some are not embedded and some are monochromatic and some; from plastic varieties, some are thermoplastic, and some of them are thermoset plastics. Therefore, special developments and special injection machines are suitable for users, have the characteristics of high performance and price ratio, technology intensive and simplified structure.
2. The opening and closing speed of the mold with high speed, efficiency and precision. The opening and closing speed of the mold has increased from 20-30 mm/min to 40-50 mm/min, and some even 60 mm/min. Injection speeds from 100 mm/450 mm/s, injection speeds of 600 mm/s for small and medium injection molding machines are not uncommon, and some can reach 900 mm/s.
Small and medium-sized injection molding machines, while large and super large are developing even giant and micro injection molding machines. 40 mn, 50 mn, locked lidamycin and even large injection machines came out. Locked 50 mn injection machine manufactured by the original West Germany, injected 24.5 kg, 140-370 mpa injection pressure.Injection molding machine manufacturers large injection molding machines with a clamping force of 120 Mn. At present, ordinary precision, precision and ultra-precision injection molding machines have reached 0.02-0.05 mm, 0.01-0.02 mm, and less than 0.001 mm.
3. Automated production is an important way to ensure product quality, increase productivity, reduce labor intensity, improve working conditions, make full use of equipment, and reduce costs. At present, many new control devices are used, such as programmable logic controllers (PLC) to replace traditional relays. Programmer control. It works reliably, and the program can be flexibly modified. Microcomputers have been used for process control, process parameters of injection machines.
This new control method is very important for forming precision products. It can automatically adjust molding conditions and ensure product size and quality. General product production machines, product packaging other than the production process test will also be automatically performed. The safety device, to ensure the safety of the equipment, can not only be automated, but also can be centrally managed to realize unmanned operation.
4. The design of other mechanical structures uses advanced methods, concepts and means, toggle lever clamping methods and direct pressure, to improve the clamping mechanism, and form a series of standardization; the appearance and shape of the main machine are optimized for design, noise reduction, injection machine and auxiliary equipment The modularization of standardization, serialization and injection machines, the development of environmentally friendly injection machines and others have led to the attention of injection molding machine manufacturers.
With the continuous acceleration of the domestic automation process, I believe that my country's injection molding machine industry will soon be technologically upgraded and transformed, and it will be improved from the technical level, and the injection molding machine will move towards automation.
