摘要
阐述了一模多孔挤压模的重要性。介绍一种半空心铝型材一模双孔挤压模结构。提出了一种分割式模芯结构以保证悬臂的强度,详细说明了这种结构的有关参数的选择与优化方法,包括挤压机能力的确定、模孔的布置以及采用计算机模拟软件进行分析对比,确定分流孔的布置、下模焊合室结构和工作带的选择。介绍了模具强度的校核方法。挤压生产实践表明,这种针对半空心型材的一模双孔挤压模结构是有效的,可以提高生产效率、降低生产成本,值得推广应用。
The paper indicates the importance of the extrusion die with multi-cavities, in-troduces an extrusion die with twin cavities for semi-hollow A1 profiles, and proposes a splitmold structure to ensure the strength of the tongue. Then the parameter selection and optimi-zation method are stated in detail, including determination of the extruder capacity, arrange-ment of cavities, and determination of portholes, the structure of mold welding chamber andbearing selection after analysis and comparison with simulation software. The method for moldstrength verification is also presented. The extrusion practice shows that this effective moldstructure enhances productivity, reduces cost and is worth popularizing.
