摘要
玉柴YC6J系列汽缸盖早期采用非整体浸涂工艺,即各砂芯分别浸涂烘干后再进行组芯,其操作工序多而繁琐,而且浸涂质量得不到很好的保证。针对存在问题提出了通过在射水道芯里加一根芯骨来实现整体浸涂工艺,不仅提高砂芯组表面浸涂质量、改善了铸件内腔质量,而且还有效降低了射水道芯断芯废品率。
The non-whole dipping process was formerly applied in Yuchai YC6J series cylinder head,cores being assemblied after being dipped and dried separately,which causes a bad guarantee to the dipping quality for the complex operating procedures.This paper introduces the whole dipping process by adding a core bar into the core,not only improving the surface dipping quality of the sand cores and the cavity quality of the casting,but effectively reduces the wasting rate of rupturing core.
