摘　　要：定型模是挤出模具的重要组成部分,采用数值模拟方法研究定型模内塑料异型材的冷却过程,可以指导定型模冷却系统的设计。本文基于传热学基本原理,分析了定型模内型材冷却过程数值模拟的初始条件和边界条件,并利用大型有限元工程分析软件ANSYS完成了型材冷却过程的数值模拟,从而证明了数值模拟用以研究型材冷却过程的有效性。Shaped mould is the important part of extrusion die for injection moulding. The cooling process of shaped plastic in shaped mould was studied using numerical simulation. The initial and boundary conditions were analyzed using heat transfer theory and ANSYS software was used to simulate the shaped plastic cooling process in the shaped mould. Results showed that numerical simulation can be used for studing the shaped plastic cooling process in the shaped mould for extrusion die.
