| 摘 要： | 传统单一恒定保压效果不佳,易导致塑料件产生较大翘曲变形,以汽车饰条为例,采用斐波那契迭代优化算法结合模流分析,对注射成型过程进行分段保压设计,通过8次迭代演算与数值模拟,获取了最优的保压压降组合,得到最小的翘曲变形量,比恒定保压塑料件翘曲量减少了37.55%,有效地控制了塑料件的翘曲量。实践证明该方案可靠有效。

Optimization of Injection Holding Process and Demoulding Design Based on Fibonacci Method |

| Abstract: | The traditional single constant pressure-holding result is ineffective, which cause relatively large distortion. Taking automotive trims as examples, adopting fibonacci iterative optimization algorithm and mold flow analysis. The design of section pressure holding to injection molding processes was conducted. Through eight times of iterative calculation and numerical simulation, optimal pressure holding and drop combination as well as minimum deformation are obtained, which decreases 37.55% compared with the deformation of relative constant pressure holding molding, which effectively control the deformation of mold parts. Practice approves that this program is effective and reliable. |
