Abstract

The FEM simulation of flow of extruding plastic gear during cooling and die design was studied in this paper. A capillary rheometer MLW-400 was used to measure the curve of shear rate VS viscosity of POM-500P, the Power Law constitutive equation was used to describe the POM rheological characteristics, the software POLYFLOW was used to simulate the structure parameters of flow channel for 16 sets of orthogonal tests, so the best structure parameters of flow channel which has good flow uniformity were obtained. The die of plastic gear was designed using the function of inverse extrusion of POLYFLOW. The cooling process of plastic gears in the vacuum shaping mold was simulated with software ANSYS, and the length of mold was determined as 160 mm.
