点を有しているものである。However, in such conventional sand removal and crushing of a lump of sand, a handling means for moving a sufficiently cooled large-sized casting flask into a polishing chamber of a fixed-type shot blasting machine after unframed. In the case of hanging with a crane, when hanging the wire rope on the large mold after unraveling, the rope must be hung so that the large casting in the molding sand that easily collapses can be stably lifted, and the moving table In case of moving the whole mold, when unraveling the large mold, it is necessary to move it once on the moving table, then perform the unraveling work on this moving table and move it by the forklift. A series of handling steps for moving a large casting to a predetermined place in the polishing chamber requires a great deal of skill and time with a great deal of skill. The dusting process of the foundry sand inevitably scatters during the casting process and the working environment becomes poor, and there is concern that workers in the field will be shunned.In addition, in the handling process and the cleaning process after unraveling the casting frame. It has various points to be improved, such as a great deal of labor for collecting scattered casting sand and shots.
