摘要
提出一种由直线超声电机驱动合模的新型超声微注塑机。首先对超声微注塑机的结构和工作原理进行分析,进而对合模-锁模-顶出机构进行了设计,最后利用ANSYS Wbrkbench软件对合模系统中质量最大的动模板进行拓扑优化以减轻其质量,并对优化后的动模板进行静力学分析。结果表明,该超声微注塑机的合模-锁模-顶出机构能够实现特定的运动,拓扑优化后合模系统总质量满足要求,且其材料强度满足要求。
In order to overcome the defects of conventional micro-injection molding machines, such as large volume, low machining accuracy, and low availability of material, a new ultrasonic micro- iniection molding machine with a linear ultrasonic motor was proposed. The structure and working principle of the machine was analyzed and designed. Topology optimization was carried out to reduce the weight of the moving platen in the clamping system using ANSYS Workbench software, and then a static analysis of the moving platen was carried out. After topology optimization, the total mass of the clamping unit met the requirements and its strength met the material performance requirements.
