摘要
介绍了一模多孔挤压模的重要性。提出了一种针对铝合金纱框型材的一模四腔挤压模结构,详细阐述了这种多孔模结构参数的选择,包括挤压机能力的选择、模孔的布置、分流孔的布置与设计、上模结构参数的优化选择以及下模焊合室设计与工作带的选择,提出了对这些参数进行优化的方式。介绍了对模具进行强度校核的方法。结果表明,这种一模四腔结构可提高生产效率、降低成本。
The importance of extrusion die with multi-cavities was introduced,and a new die structure with one die and four cavities for the aluminum alloy window frame was presented.The selection of the structural parameters was described in detail,including the selection of the extrusion capacity,the layout of cavities,the layout and design of the diverter hole,the optimization of the structural parameters of the upper die,and the design of the welding chamber of the lower die and the selection of the working belt.The optimization of these parameters was proposed.The method of checking the strength of die was introduced.The results show that the structure with one die and four cavities can improve production efficiency and reduce cost.
