摘要
阐述LJ465Q曲轴箱的主坭芯制芯工艺,即由原来的坭芯分半出芯而后粘合改进为整体出芯。与原工艺相比,有抽芯顺畅,坭芯无需粘合,无需烘干,尺寸精度高,气孔缺陷少,废芯率低的特点,且坭芯壁厚均匀,重量减轻。
It is presented in the paper the improvement of coremaking process from separated to integrated for LJ465Q crankcase. Compared with the existing process, it is characterized by smooth core extracting, high accuracy, even core wall and light in weight, with less porosity and low waste core, but without binding and drying.
