中文摘要: |
针对目前高脚椅子类塑料制品在设计气辅模具时,存在强度不够、表面质量差、成型困难等缺陷,利用CAE技术
进行进气系统优化,并用正交试验进行成型工艺优化,最终得到最优的气辅成型设计方案和成型工艺参数。应用结果表

英文摘要: |
The plastic part of chair with long legs has the defects of low strength, poor surface quality and filling difficulty.
The CAE technology was applied to make optimization of gas injection system and apply orthogonal design to adjust the
injection parameter to get the best gas injection design and injection parameter. The results of the mold manufacture show
that the gas nozzle opening in the necessary position helps the gas injection. The injection parameters that effect the gas
injection is following, the melt filled volume > gas pressure > gas delay time > melt injection temperature. |
