摘要
对某型柴油机缸盖在生产过程中出现的质量问题进行了分析,找出了缺陷产生的原因,并制定出相应的解决措施:一是通过增加型腔出气和加强坭芯排气,降低了缸盖上平面气孔缺陷;二是调整冒口尺寸及增加冷铁,消除了密封试验时的漏水、漏气现象。
The quality problems of a diesel cylinder head during the production were analyzed. The reasons of the dcfects were found out. Corresponding solutions were constituted. One is by increasing the cavity air out and the core exhaust, so that gas holes of the cylinder head on upper plane were reduced. Two is adjusting the size of the riser and adding the chillers, so that the water leakage and gas leakage phenomenon in the seal test were eliminated.
