摘要
针对铝合金圆筒形底座,结合企业的实际生产情况,采用数值模拟软件Flow-3D对铸件3种不同浇注方案的充型过程进行模拟分析,以确定最佳的进浇系统.对比3种不同方案充填过程料流和卷气分布的模拟结果,确定了带分流区的搭接扇形浇注系统方案.据此方案的金属液流向和卷气位置,设置了真空排溢系统,通过模拟分析了设计方案的合理性.
The filling process for three different pouring gating system schemes of cylindraceous die casting mold was simulated by Flow-3D numerical simulation software to find the optimum gating system. The fanshaped gating system with lapping bifurcation region was then selected by comparison of the results of three simulation schemes, a vacuum vent-centralized slag system was set accordingly and justification of the scheme was conducted as a summary.
