摘要
为了提高盘式螺杆微注塑机的塑化性能,通过多物理场建模仿真软件对其塑化过程进行了数值模拟,并对其动盘进行了结构优化。首先对动盘的结构参数进行了理论分析,然后对参数改变后的结构进行仿真计算与分析,探究各参数对塑化性能的影响规律,最终结合各参数对塑化性能的影响能力,考虑盘式螺杆实际情况设计出了动盘优化结构。结果表明,采用通过缩小动盘原型结构中的槽道宽度而留出空间构造3条螺槽的优化动盘结构,可以使盘式螺杆微注塑机的塑化性能明显提高。
To improve the plasticizing performance during the processing,the plasticizing process of disk screw micro-injection machine was numerically simulated through multi-physical field modeling using a simulation software,and the structure of disc screw was optimized.Theoretical analysis was first carried out on the structural parameters of the moving plate,and then simulation calculation and analysis were performed on the structure through changing the structural parameters.The influence of each parameter on the plasticizing performance was evaluated.Finally,an optimized structure of disc screw was designed through combining the effect of various parameters on the disc screw of plasticizing capability and considering the actual situation of the disc screw.The results indicated that the plasticizing performance of the disc screw micro-injection molding machine was improved significantly through using an optimized disc screw structure with a reduced groove width in the prototype structure to leave space to construct three screw grooves.
