大功率柴油机缸盖冷芯盒铸造工艺研究

Research on Cold Core Box Casting Process for a High-Power Diesel Engine Cylinder Head

根据某型柴油机缸盖的结构特点,设计了缸盖的冷芯盒铸造工艺及生产流程。生产表明,采用冷芯盒制作方法,从原材料准备、混合料的配制、射芯、吹三乙胺固化、余气净化洗涤等工序,实现了快速连续生产,制备了满足技术文件要求的高精度、高质量柴油机缸盖。

According to the structural characteristics of diesel engine cylinder head,cold core box casting process and production flow of cylinder head were designed.The production practice shows that by using the cold core box manufacturing method,the rapid and continuous production is realized from the processes of raw material preparation,mixture preparation,core shooting,blowing triethylamine curing,residual gas cleaning and washing,and the high-precision and high-quality diesel engine cylinder head meeting the requirements of technical documents is prepared.
