摘　　要：以手机外壳注塑模具为例,利用有限元分析软件ANSYS Workbench对手机外壳注塑模具的刚强度进行分析。在注塑成型过程中模具内壁会因热载荷及压力载荷产生变形对制品的成型精度产生影响,因此需对成型过程模具的变形量进行研究,保证制品的成型精度。主要以ANSYS workbench中的稳态热分析及静力结构分析模块进行耦合对注塑成型过程中模具内壁的变形进行模拟,并根据模拟分析的结果对模具质量进预测,为模具的设计及材料的选择提供依据。This paper takes the injection mould of the Cellphone shell as an example,using the FEM software ANSYS workbench to analyze the stiffness and strength of the injection mould of Cellphone shell.During injection,the inner surface of the mould will go through deformation because of the thermal load and pressure load and the mould accuracy will be influenced.Therefore the mould deformation during the injection needs to be studied to ensure mould accuracy.In this paper,the deformation of the inner surface of the mould is simulated during injection by the coupling of the Steady-State Thermal and the Static Structural in ANSYS workbench,and the mould quality bases on the simulation results can be predicted.This can also provide reference for mold design and the material selection.
