SAND MOLD FOR CASTING AND METHOD FOR PRODUCING THE SAME
To provide a sand mold for casting and a method for manufacturing the sand mold that reduces chipping in a corner of a contact surface with a casting of a sand mold for casting, and provides a casting having a small number of unnecessary protrusions in a corner of the casting.SOLUTION: A sand mold for casting comprises at least sand and a binder. At least a part of a corner of a contact surface of the sand mold for casting is an R-face or a C-face. A dimension of the R-face or C-face is 5 times or more as large as a mode diameter of the powder material constituting the sand mold. It is thus possible to obtain the sand mold for casting having few chippings in the corner of the contact surface of the sand mold.SELECTED DRAWING: Figure 8
【課題】鋳物用砂型の鋳物との接触面の角部の欠けが少なくなり、鋳物の隅部に不要な凸が少ない鋳物を得ることができる鋳物用砂型、およびその製造方法を提供する。【解決手段】少なくとも砂および結合材を含む鋳物用砂型であって、前記砂型の鋳物との接触面の角部の少なくとも一部がＲ面またはＣ面となっており、前記Ｒ面またはＣ面の寸法は、前記砂型を構成する粉体材料のモード径の５倍以上である。これにより、砂型の鋳物との接触面の角部の欠けが少ない鋳物用砂型とすることができる。【選択図】図８
