摘要
介绍了急冷急热技术的工作原理及其在Moldflow软件中的分析方法,抽取了10组不同结构的空调高光面板分别进行了急冷急热分析及普通冷却分析,对得到的分析翘曲变形结果与实际生产变形结果进行了比较。使用ANSYS软件分析蒸汽管道直径与水路到模腔表面的距离对模具加热时间和模腔表面温度的影响。结果显示,急冷急热分析的翘曲变形结果与实际生产的变形比较接近,蒸汽管道直径与水路到型腔的距离对模具的加热时间与温度有较大的影响。经优化模具蒸汽管道系统设计及注塑填充+保压参数后,模具加热效率提高了16%,总周期缩短了17.8%。
The theory of rapid heat cycle molding(RHCM)and its analysis method in Moldflow software were introduced.Ten groups of high gloss panel of air conditioning with different structures were selected for RHCM analysis and common cooling analysis respectively.The results of warpage analysis and actual production deformation were compared.ANSYS software was used to analyze the influence of the diameter of steam pipeline and the distance from water channel to the surface of the mould cavity on the heating time of the mould and the surface temperature of the mould cavity.The results showed that the warping deformation in RHCM analysis was close to the actual production.The diameter of steam pipeline and the distance from water channel to cavity had a great influence on the heating time and temperature of the mould.After optimizing the design of steam pipe system,injection filling and packing parameters,the heating efficiency of the die was increased by 16%,and the total cycle was shortened by 17.8%.
