An apparatus for placing the supporting plate such that it can move back and fore freely on the bottom of the moving short wall of the mold is provided. In order to smooth the movement of the short wall of the mold, a lubricating agent may be placed at a portion where the long walls contact the short wall of the mold, or holes or grooves for supplying lubricating agent may be provided on both ends of the short wall of the mold.
An apparatus for enlarging the width of a cast piece which comprises a single mold consisting of a pair of opposed longitudinal walls and a pair of transverse walls extending between said longitudinal walls in contact therewith, at least one of said transverse walls being movable relative to said longitudinal walls for enlarging the width of the mold;
