摘要
分析了493缸盖铸件粗加工后罩边壁厚偏薄、底面气道座圈单边缺料、底面138尺寸水孔偏移尺寸问题的原因,采取调整优化托盘芯定位、贴补外模罩边内侧、对排气道芯盒局部进行工艺贴补、降低浇注温度等措施,有效改善了上述问题。
The causes of 493 cylinder head casting dimension problem is analyzed,such as the thin wall thickness of cover side,the lack of material for valve seat ring,the deviation of the water hole.Effective measures are carried out by adjusting the core positioning block,optimizing the gripper of sand core,patching of exhaust core box and reducing the pouring temperature.
