The processing performance of metal molds reflects six aspects
All kinds of things and products we use in our daily production and life, ranging from the base of the machine tool, the shell of the fuselage, to the shell of a head screw, button and various household appliances, automobiles, railways, aerospace are all related to Mold has a close relationship.
Metal molds are used in industrial production, using various presses and special tools installed on the presses to make metal materials into parts or products of the desired shape through pressure. Such special tools are collectively referred to as metal molds. The following are six aspects of the processing performance of the metal molds organized by Dongmo.
1. The increasing size of mold forming parts and the high productivity of parts require a mold with multiple cavities, resulting in increasingly large molds. Large-tonnage molds can reach 100 tons, with hundreds of cavities and thousands of cavities in one mold, requiring mold processing equipment. Large worktable, enlarged Y-axis and Z-axis travel, large load-bearing, high rigidity and high consistency.
2. The hardness of the mold steel material for mold processing is high, and the mold processing equipment is required to have thermal stability and high reliability.
3. The refinement of mold processing makes the composite and high efficiency of processing equipment more and more attractive. High-speed milling has many advantages, such as the ability to process high-hard materials, stable processing, small cutting force, and small heating and deformation of the workpiece, which makes mold enterprises pay more and more attention to high-speed machining.
4. The combination of processing skills and green product skills will be taken into consideration when enterprises purchase equipment. The radiation of EDM machines and the selection of media will be factors that affect safety and environmental protection. EDM milling skills will be developed in the field of mold processing in the future.
5. High dynamic precision. The static performance introduced by machine tool manufacturers (such as repeat positioning accuracy and linear feed rate cannot reflect the actual processing situation during the three-dimensional surface processing of the mold. The high-precision machining of the three-dimensional curved surface of the mold also puts forward the requirements of high dynamic precision performance, high speed and high speed. High precision is only possible when the machine tool's high rigidity, thermal stability, high reliability and high-quality control system are combined.
6. For complex cavities and multi-functional composite molds, with the complexity of the shape of the parts, it is necessary to improve the design and production level of the molds. Many grooves and materials are formed in a set of molds or assembled into components. Functional composite molds require a large amount of processing programming programs, high deep hole induction cutting ability and high stability, which increases the processing difficulty.
