Five development trends of plastic mold processing technology
At present, the proportion of plastic mold in the whole mold industry is about 30%, in the mold import and export proportion as high as 50-70%.In recent years, the development of plastic mold in China is rapid, and the application of plastic products is increasingly extensive, providing a very broad market for plastic mold.
The general trend of the mold market is steady and upward. In the future mold market, the development speed of plastic mold will be higher than that of other molds, and the proportion in the mold industry will gradually increase.And the plastic mold processing technology generally presents the following development trend:
1. The increasing size of mold-forming parts and the high productivity of the parts require multi-cavity mold, leading to the increasing size of molds. Large molds with large tonnage can reach up to 100 tons.
2. The mold material used is of high hardness and requires high thermal stability and reliability of the mold processing equipment.
3. For complex cavity and multifunctional composite mould, as parts of complicated shape, must improve the level of mould design and manufacture of a variety of groove, a variety of material in a mold forming or assemble components of multifunctional composite mould, requires large amount of processing programming procedures, with comprehensive Gao Shenkong cavity cutting ability and high stability, improve the processing difficulty.
4. The delicacy of mold processing makes the complexity and efficiency of machining equipment more attractive.High speed milling has many advantages, such as high hard material processing, smooth processing, small cutting force, small workpiece heating deformation, etc.
5. High dynamic accuracy.The static performance introduced by machine tool manufacturing enterprises cannot reflect the actual machining situation in the three-dimensional mold surface machining.The 3d curved surface of the mold is processed with high precision, and the requirement of high dynamic precision is also put forward. The high speed and high precision can only be realized by cooperating with the high rigidity, thermal stability, high reliability and high quality control system of the machine tool.
