なお、 上・下鋳枠2・4が分離したマッチプレート7は、図示しないマッチプレート搬入出機構の上に載る。
Subsequently, as shown in FIG. 2 b, the pressure oil is continuously supplied to the side of the first hydraulic cylinder 5, 5 where the piston rod 1, 1 is extended, and the first hydraulic cylinder 5, 5 is moved to the stroke end. The upper casting frame 2 in the upper mold A is lifted up to the rising end, and the piston rods 1 and 1 in the first hydraulic cylinders 5 and 5 are moved along with the extending operation up to the stroke end of the first hydraulic cylinders 5 and 5. The oil discharged from the side to be contracted is returned to the hydraulic tank 17 by switching the four-way opening direction switching valve 20 after filling the side of the second hydraulic cylinders 8 and 8 for extending the piston rods 6 and 6. .
The match plate 7 from which the upper and lower casting frames 2 and 4 are separated is placed on a match plate loading / unloading mechanism (not shown).
