摘　　要：介绍了制动凸轮的熔模铸造技术。一些新工艺和工艺参数成功地应用于球墨铸铁凸轮铸件试生产中,例如,无冒口铸造技术、增强自补缩效果的浇注系统,铸件浇注温度控制在1420℃左右,模壳温度控制在700℃左右等。其结果有效地改善了铸件质量。Investment casting process for locking cam was introduced. Some new technologies and parameters were successfully used in trial production of ductile iron cam, such as no-riser casting technology, the gating system with enhanced self-feeding effect, the casting pouring temperature around 1420℃ and shell mold temperature around 700℃ and so on. As a result, the castings＇ quality is improved effectively.
