摘　　要： 采用MoldFlow PI 6.1软件,以聚苯乙烯(PS)为原料,在成型工艺条件不变的情况下,研究几何形状(微结构的位置、倾角、截面尺寸、深宽比和型腔的尺寸)对注塑件微结构填充高度的影响。结果表明:微结构的位置距离浇口越远,填充高度越大;同一位置微结构的填充高度随倾角的增大而减小;微结构的填充高度随微结构的宽度的增大而增大;微结构的填充高度随微结构深宽比的增大而减小,并且填充高度减小的趋势逐渐变缓;微结构的填充高度随型腔宽度或型腔高度的增大而减小。 Influences of geometry, such as the position, obliquity, sectional dimension, aspect ratio of the micro structure and dimensions of the cavity, on filling height of micro structures of injection molded part were studied by MoldFlow MPI 6. 1 software with polystyrene （PS） as raw material under the same processing condition. The results showed that with the increasing of the distance between the microstructure and the gate, the filling height became bigger; when the obliquity of the microstructure at the same position became bigger, the filling height became smaller; when the width of the microstructure increased, the filling height increased too; with the increasing of the aspect ratio of the microstructure, the filling height decreased, and the decrease of the filling height was gradually slowing down ; when the width or height of the cavity increased, the filling height became smaller.

关 键 词： 微结构 微注塑 深宽比 填充高度
