摘要: 利用正交实验和注射压缩成型方法,考察了温度和压缩工艺参数对薄壁制品不同位置3处微结构充填的影响。结果表明,距离浇口远近不同的微结构,其充填的影响因素不同;与温度因素相比,压缩工艺参数对微结构的充填起关键作用;压缩工艺参数中的打开距离和压缩速度对3处微结构的充填影响都较大,且打开距离越小,压缩速度越大越有利于微结构的充填。

Abstract: Influences of temperature and technical parameters of injection compression molding on microstructure filling effect in three different positions of thin-wall products were investigated by an orthogonal experiment and an injection-compression molding method. The results indicated that the different distances from the sprue gate of microstructure generated different influences on the filling. Compared with the temperature as a factor, technical parameters of compression process played a pivotal role on the microstructure filling. The effects of open distance and compression speed on the filling in the three microstructures were much greater than others in the technical parameters. A smaller open distance value and a larger compression speed value were advantageous to the microstructure filling.
