塑料模具加工工艺的五大发展趋势

1.模具成型零件的日渐大型化和零件的高生产率，要求一模多腔，致使模具日趋大型化，大吨位的大型模具可达100吨，一模几百腔、上千腔，要求模具加工设备大工作台、加大y轴和z轴行程、大承重、高刚性，高一致性。 2.采用的模具钢材料硬度高，要求模具加工设备具有热稳定性、高可靠性。 3.对复杂型腔和多功能复合模具，随着制件形状的复杂化，必须要提高模具的设计制造水平，多种沟槽、多种材质在一套模具中成形或组装成组件的多功能复合模具，就要求加工编程程序量大，具有高深孔腔综合切削能力和高稳定性，提高了加工难度。 4.模具加工的精细化，使加工设备的复合性、高效性更加引人关注。高速铣削具有的可加工高硬材料、加工平稳、切削力小、工件升温变形小等诸多优点，使模具企业对高速加工日益重视。 

1. the growing size of the moulded parts and the high productivity of the parts require a multi cavity of a mold, which makes the mold become more and more large, the large tonnage of the large mold can reach 100 tons, one mould hundreds of cavities and thousands of cavities, and the large work table of the mould processing equipment, the Y axis and the Z axis, the large load, the high rigidity and the high consistency are required. 2. the die steel material used is of high hardness and requires the die processing equipment to have high thermal stability and high reliability. 3. for complex cavity and multi-function compound die, with the complexity of the shape of the workpiece, it is necessary to improve the design and manufacturing level of the mold. Many kinds of grooves and many kinds of materials are formed or assembled into components in a set of moulds. It requires a large number of programming programs, with the comprehensive cutting ability and high stability of the high depth cavity cavity. The difficulty of processing is improved by qualitative analysis. 4. the refinement of mold processing has attracted more and more attention to the complexity and efficiency of machining equipment. High speed milling has many advantages, such as Machinable high hard material, smooth machining, small cutting force, small workpiece heating, and so on, which make the mould enterprises pay more and more attention to high speed machining.
