Is to be done.

  As described above, the shell solidified body 2 'is filled and solidified by the height of the inner end 4C and the outer end 4D of the U-shaped steel edge 4K and the thickness width of the steel outer 4B. It can be set as the molded object 1 provided with high intensity | strength. Further, when the shell solidified body 2 ′ of the main body 3 is completely solidified, a removing agent (not shown) is applied or sprayed to an appropriate position of the corrugated cardboard material 7 as the inner mold frame, and the corrugated cardboard material 7 is peeled off to perform the removing operation.

  Next, the removal operation of the corrugated cardboard material 7 will be described. As shown in FIG. 4, the corrugated cardboard material 7 which is an inner mold used in this embodiment has a thin spiral wall 7L. When peeling, the spiral 7L is peeled off from the spiral 7L of the tip 7T of the spiral 7L. Since the spiral 7L is thinner than the other portions, the cardboard material 7 can be easily peeled off by tearing from here, and a perforation may be provided as the spiral 7L serving as a tearing portion. .
