为了提升微结构注塑机的成型精度,提高合模系统的合模力稳定性和运动特性尤为重要。文章设计了由伺服电机驱动的1300 k N微结构注塑机的合模系统。在此基础上,建立了该系统的三维几何模型,并在Adams虚拟样机环境中对开合模过程进行了多体系统动力学及运动学仿真。仿真结果表明,在移模速度600 mm/s时,合模系统的开合模运动保持相对平稳。这对于保证制品质量和提高成型加工效率具有重要意义。此研究为提高微结构注塑机合模系统的设计精度和成型质量提供了理论依据。
In order to improve the forming precision of the microstructure injection molding machine, it is very important to improve the mold clamping force stability and the movement characteristics of the mold clamping system. The paper designs a clamping system of a 1300 kN micro-structure injection molding machine driven by servo motor. On this basis, a three-dimensional geometric model of the system is established, and multi-body system dynamics and kinematics simulation of the opening and closing process are carried out in Adams virtual prototype environment. The simulation results show that the opening and closing modes of the clamping system remain relatively stable at the moving speed of 600 mm / s. This is of great significance to ensure the quality of products and improve the efficiency of forming and processing. This research provides a theoretical basis for improving the design accuracy and forming quality of the mold clamping system of microstructured injection molding machine.
