及び作業効率の向上が図れる。By forming a concave portion in the bent portion of the back surface of the preform by the protrusion provided at the tip of the protruding corner of the bent portion forming the molding portion of the auxiliary mold having the pressing portion, the corner portion of the bent portion of the back surface is formed. Since the material does not deviate, it is easy to press the bent corners of the preform from the back so that it fits along the molding die and easily form a neat bending line of the desired shape in a single operation. Since it is possible to deal with sharp bending lines, it is possible to easily obtain a stepped plate-shaped artificial stone product with a bent portion as an integrally molded product without processing and joining, improving product quality and improving work efficiency. Can be improved.
