摘　　要：以实际生产的支持块为例,结合3D技术,模拟了注射成形喂料在复杂几何模腔中的流动情况。基于ANSYS提供的Z Buffer切片模型空间观测方式,预测了实际制品缺陷产生的部位并分析了缺陷形成机理。最后依据模拟结果,推荐在实际生产中采用INLET4位置浇口进行注射生产,实验表明制得的支持块无缺陷,产品通过了有关部门的验收,证明了充模流动3D模拟的可行性和准确性。The 3D simulation of the process of filling a complicated cavity was illustrated, the positions of defects were predicted and the mechanisms was discussed. Prior to the practical production, the die filling behavior of new inlets were simulated. Finally, the INLET4 was recommended as the optimal injection position. Good products that have passed through the acceptance check of relative department are made according to the simulation results.
