挤出模的基本流道仿真研究

Simulation of the Basic Fluid Channel of Allotype Plastic Profile Extrusion Die

将图形仿真技术引进模具的设计和修整过程中,利用符合客观实际的数学模型分析流体的流变行为,在计算机上通过图形显示各个关键参数,观察产品的正品率,力求使流体在出模处达到速度一致,并避免材料的浪费,缩短设计周期.

This paper brings the graphic simulation technology into the design and regulation of al-lotype plastic profile extrusion die, builds up a practicable mathematical model for analyzing the later developments of plastic fluid. In order to observe the rate of qualified products and fulfill the constant velocity of the fluid coming from the extrusion die, all important parameters are graphically shown on the computer.
