There are some basic principle in choosing mold steel.
30%, and the proportion in the import and export of mould is as high as 50~70%. Of plastic products
It is widely used and provides a very broad market for plastic molds.
In addition, driven by high technology and the application demand of pillar industries,
China's plastic mold has formed a huge industrial chain, from the upstream raw and
auxiliary materials industry and processing and testing equipment to the downstreamapplication
industries such as machinery, automobiles, motorcycles, household appliances, electronic communication, building materials, etc.
At the same time, there is a great demand for plastics in construction, home appliances,
automobile and other industries. It is estimated that the automobile and motorcycle industries alone need more than 10 billion
yuan of plastic molds every year, and the market of color TV plastic molds is about 2.8 billion yuan every year.
It can be seen that the overall trend of die market is stable and upward. In the future die market, the development speed of p
lastic dies will be higher than other dies, and the proportion in the die industry will gradually increase. Development trend oplastic mold processing technology
(1) The increasing size of mold forming parts and the high productivity of parts require multiple cavities in one mold, which leads to the increasing size of molds.
Large-tonnage molds can reach 100 tons, with hundreds of cavities and thousands of cavities in one mold, which requires large workbench for mold processing
equipment, increased Y-axis and Z-axis travel, large load-bearing, high rigidity and high consistency.
(2) The die steel processed by die has high hardness, which requires the die processing equipment to have thermal stability and high reliability.
(3) For complex cavities and multi-functional composite dies, with the complexity of the shape of parts, it is necessary to improve the design and
manufacturing level of dies. Multi-groove and multi-material are formed or assembled into a multi-functional composite die in a set of dies, which
requires a large amount of processing programming procedures, comprehensive cutting ability of deep cavities and high stability, which increases the processing difficulty.
(4) The refinement of mold processing makes the complexity and high efficiency of processing equipment attract more attention.
High-speed milling has many advantages, such as machining high-hard materials, stable machining, small cutting force, small deformation of workpiece
due to heating and so on, which make die enterprises pay more and more attention to high-speed machining.
(5) High dynamic accuracy. Static performance introduced by machine tool manufacturers can't reflect the actual
machining situation when machining three-dimensional mould surface. High-precision machining of three-dimensional curved
surface of die puts forward the requirement of high dynamic precision performance. High speed and high precision can only be realized
with the cooperation of high rigidity, thermal stability, high reliability and high quality control system of machine tool.
