摘要

摘要本研究通过注射成型生产了一种盒状产品，并在注射成型机的喷嘴和模腔处安装了压力传感器。对各种工艺参数进行了注塑实验，以了解型腔、喷嘴和油泵压力之间的相关性。在研究中可以发现油压和喷嘴压力之间的高度相关性（R>0.95）。注塑机中的油压可以充分描述熔融塑料在喷嘴处的压力变化。然而，由于注射速度、熔化温度和填充时间的变化，喷嘴压力和腔体压力之间的相关性略有降低。因此，合适的成型窗口可以改善油压、喷嘴压力和型腔压力之间的相关性。这项研究提供了三种压力之间的相关性，并为未来选择过程变量提供了参考，这是在线监测的一个重要预处理。

Feasibility assessment of injection molding online monitoring based on oil pressure/nozzle pressure/cavity pressure

Abstract This study produced a box-like product through injection molding, and pressure sensors were installed at the nozzle in the injection molding machine and mold cavity. Injection molding experiments were conducted with various process parameters to understand the correlations between the pressure of the cavity, nozzle, and oil pump. A high correlation (R > 0.95) between oil pressure and nozzle pressure could be found in the study. The oil pressure in the injection molding machine could fully describe the pressure variation of the molten plastic at the nozzle. However, the correlation between nozzle pressure and cavity pressure was slightly reduced due to changes in injection speed, melting temperature, and packing time. Thus, a suitable molding window can improve the correlation between oil pressure, nozzle pressure, and cavity pressure. This study provides a correlation between the three pressures and a reference for the future selection of process variables, an essential pretreatment for online monitoring.
