摘　　要：针对注塑生产过程中注塑机喷嘴中心线与模具主流道入口中心偏离而造成的塑件质量问题,研究了一种模具自动定位方法。主要是通过PLC控制载有模具的工作平台进行Y,Z坐标移动,依据所输入模具的尺寸自动对准注塑机喷嘴中心线与模具主流道入口中心,直至偏距显示为零,解决了注塑机喷嘴中心线与模具主流道入口中心偏离问题。实验表明,模具自动定位方法提高了安装定位精度与效率。Aiming at the quality problem of plastic parts caused by the deviation between the nozzle center line of injection molding machine and the inlet center of the main runner in the injection molding process,this paper studies an automatic positioning method of the mold.It mainly controls the Y and Z coordinate movement of the working platform with the mold through PLC,and automatically aligns the center line of the injection molding machine nozzle and the center of the main channel entrance of the mold according to the size of the input mold until the offset is zero.The problem that the center line of the injection nozzle deviates from the center of the main channel entrance is solved.The experimental results show that the proposed method can improve the accuracy and efficiency of die installation and positioning.
