For, in order to realize sand molding, mold taking, pouring riser setting and sand core installation, the sand mold should be composed of two or more parts. The dividing or assembling surface of sand mold is called parting surface. The proper selection of parting surface is of great significance for process optimization.
Combined with the analysis of the characteristics of the axle housing parting surface and related data, the location of the axle housing parting surface is shown in the figure. Because the turnover mold is not only labor intensive, but also easy to cause casting defects such as sand core moving, sand dropping and fire running, in order to reduce the workload and prevent mold damage, the selection of parting surface should be consistent with the pouring position.
