摘要
设计并制造了一种注塑模具型腔信息在线检测装置,综合利用传统传感器检测法、可视化观测法和超声波检测法,分别检测塑料熔体在模具型腔中的热、力学变化情况,以及充填模式信息和微观形态演化行为.在检测装置中,塑料模具设计成带侧向分型抽芯的模具结构,同时运用多媒体计时器技术和多线程编程技术开发数据采集系统.实验结果表明:所设计的模具安全可靠,检测装置可获得成形过程中塑料熔体的温度及压力信息、充填模式图像和结晶形态的形成与演化行为,实现真实加工条件下注塑成形过程的全面可视化.
A new device for on-line monitoring cavity information during inj ection molding was de-signed and developed.Traditional sensors,visual observation method and ultrasonic detection method were employed to monitor the heat and force history,the filling mode information and the micromor-phology evolution behaviors for molten polymers,respectively.In the monitoring device,the struc-ture of injection mold was designed as a side core pulling structure.Moreover,a multimedia timer and a multi-threaded programming technique were adopted to develop data acquisition system.Experimen-tal results show that the designed injection mold is safe and reliable,while the developed monitoring device is available to obtain the information of temperature,pressure,filling mode and crystallization behaviors for molten polymers during processing,providing a comprehensive visualization of injection molding process,and it has wide application prospects in producing high quality products.
