通过模腔压力传感器测量模腔压力,研究模具不同部位的模腔压力曲线,测量注塑过程中的模腔压力和塑料制品残余应力,研究模腔压力曲线与塑料制品残余应力的关系。在此基础上,探讨注射压力和保压压力对模腔压力曲线形状的影响规律。实验结果表明:模腔压力曲线和塑料制品残余应力、注塑工艺参数有很大的关系。
通過模腔壓力傳感器測量模腔壓力,研究模具不同部位的模腔壓力麯線,測量註塑過程中的模腔壓力和塑料製品殘餘應力,研究模腔壓力麯線與塑料製品殘餘應力的關繫。在此基礎上,探討註射壓力和保壓壓力對模腔壓力麯線形狀的影響規律。實驗結果錶明:模腔壓力麯線和塑料製品殘餘應力、註塑工藝參數有很大的關繫。

Cavity pressure was measured by cavity pressure sensor to study cavity pressure in different position of injec-tion mold.Cavity pressure and plastic part residual stress during the molding process were measured to study the relation-ship between them.On the basis,the effects of injection pressure and packing pressure on cavity pressure curve configu-ration were discussed.The experiment result shows that cavity pressure has a close connection with plastic part residual stress and injection parameters.
