| ：针对浇注系统的不合理设计对制品质量产生重要影响的问题，提出利用综合平衡法对浇注系统优化的方案。以
塑料花盆件为研究对象，在Pro/E中建立模型，借助Moldflow的分析功能，选用PP材料，采用点浇口填充方式；结合正交
试验法来分析塑件结构、浇口尺寸和浇口个数对制品翘曲变形量和体积收缩率的影响规律；采用极差分析法分别研究产
生最小翘曲变形和最小体积收缩率时的因素组合；运用多目标综合平衡法，选出同时满足最优翘曲变形量和体积收缩率
的因素组合，并进行验证分析，从而证明了优化方案的合理性。该设计控制了收缩变形的产生，使产品质量得到了一定
改善，为模具设计提供了参考。 |

| Aiming the problem that the unreasonable design of gating system seriously affect the product quality, this
paper proposed an optimal design scheme of gating system based on integral balance method. The plastic flowerpot as
research object, established the model in Pro/E. using the analysis function in Moldflow. chose PP as material, filling
with the point gate. Combined with orthogonal test method to analyze the influence of product structure, gate size and
gate number on warping deformation and volume shrinkage ratio. Studied the factor combinations of minimum warpage
and minimum volume shrinkage ratio by range analysis method. Using the integral balance method. selected the factor
combination which meet the minimum warpage and the minimum volume shrinkage ratio at the same time. then verified
the combination scheme by simulation. so as to prove the rationality of optimum gating system scheme. The design
controls the generation of the shrinkage deformation, improves product quality, provides reference for mould design. |
