摘要
汽车曲轴箱与滤清器连接处的密封要求相对较高,该部位相对较厚、尺寸较大、结构复杂,壁厚不均匀,容易出现烧伤和气孔缺陷。因此,此类零件经常漏气,质量相对较差。以汽车曲轴箱的质量改进为目标,模具使用3D打印的随形冷却镶件进行优化,采用高真空压铸工艺,以改善铸件缺陷区域的烧伤和气孔,提高铸件品质。
In view of the high sealing requirement at the connection between automotive crankcase and filter,the features of relatively thick,large,complex,and an uneven wall thickness are prone to defects such as burns and pores.Therefore,leak air are commonly occurred in the component with poor quality.With improving quality of automotive crankcase as target,the mold was optimized by 3D printed conformal cooling inserts,and high-vacuum die-casting process was utilized to eliminate burns and pores in the defect areas of castings,thus enhancing the casting quality.
