Determination of main sand casting parting surface of axle housing

For sand casting, in order to realize sand molding, mold taking, setting pouring riser and installing sand core, the sand mold should be composed of two or more parts. The division or assembly surface of the sand mold is called parting surface. Proper selection of parting surface in sand casting is of great significance for process optimization.

Based on the analysis of the characteristics of the parting surface of the sand casting axle housing and relevant data, the location of the parting surface of the sand casting axle housing is shown in the figure. Because the turnover mold not only has high labor intensity, but also easily causes casting defects such as sand core movement, sand falling and fire running, in order to reduce the workload and prevent damage to the mold, the selection of parting surface should be consistent with the pouring position.
