模板是注塑机合模机构的重要组成部分,在注塑机中有固定模具和运动导向作用。在注塑机的设计和使用过程中,模板的变形十分复杂,其性能直接影响到注塑机的成本、精度和使用寿命。通过ANSYS有限元分析和模板的应力、应变计算,提出模板分析和优化设计方法,并在机器上实际测量了模板的变形。通过定模板的数值分析和实验测量数据的对比,验证了所提出方法的有效性。此方法可以用于指导模板结构的设计,实现应力分布优化,进而提高注塑机的寿命、节约模板材料。
Template is an important part of injection molding machine clamping mechanism, a fixed mold in the injection molding machine and motion-oriented role. In the design and use of injection molding machine during the process, the deformation of the template is very complex, and its performance directly affects the injection molding machine cost, accuracy and service life. Through the finite element analysis of ANSYS and the stress and strain calculation of the formwork, the template analysis and optimization design method are put forward, and the deformation of the formwork is actually measured on the machine. By comparing the numerical analysis of the fixed template and the experimental measurement data, the validity of the proposed method is verified. This method can be used to guide the design of the template structure, to optimize the stress distribution, thereby increasing the life of the injection molding machine, saving template material.
