Paper Title:
Numerical Simulation of Compacting Process of Green Sand Molding Based on Sand Filling
  Abstract

The mathematical models of compacting process in green sand molding were built up based on the experiment results of molding sand property testing, in which the nonlinearity problems involved in the molding sand material, the pattern geometry and the contact between sand and flask were considered. These models were then used to numerically simulate the compacting process of green sand and predict the hardness distribution of green sand mold. The effect of sand filling on the initial sand density distribution was taken into account, which was obtained through the two phase flow simulation of sand filling. The predicted results were compared with the measured ones and good agreement was obtained.
