摘要
针对双子弹模压机异型模杯成型时出现的黄变、破损等问题,构建UG异型模,采用Fluent进行热流耦合数值模拟,编写UDF程序控制涡旋风入口条件,采用正交试验法进行极差分析,得出最佳异型模模具的参数。通过实测异型模具表面温度,并与数值模拟数据对比。结果表明:双子弹模压机可达到高表面质量的异型模杯成型要求,符合实际生产的模具需求。
As to the problem of yellowing and breakage during the molding of the double-die molding machine,the UG shaped mold was firstly constructed,and thermal flow coupling numerical simulation was carried out by Fluent afterwards.Then the UDF program was adopted to control the vortex wind inlet condition.By orthogonal test method,range analysis was performed to abtain the parameters of the best profiled mold.Besides,the surface temperature distribution of the mold was measured.The results show that the twin-shot molding machine can meet the molding requirements of the high-surface quality profiled cup,with which the actual production requirements of the mold is in line.
