PCT No. PCT/JP97/00888 Sec. 371 Date Nov. 13, 1997 Sec. 102(e) Date Nov. 13, 1997 PCT Filed Mar. 19, 1997 PCT Pub. No. WO97/34719 PCT Pub. Date Sep. 25, 1997An interior cooling inner plunger is caused to project from an outer plunger after casting. Alternatively, during casting, while it projects from the outer plunger, the inner plunger is inserted into a frustoconical gate. Subsequently, a pressure pin is moved downward from a movable mold side to a portion near a gate portion. When a melt solidifies, a casting sleeve and a casting plunger are moved downward, and a pressure pin is further moved downward to cut apart a biscuit from a mold product. An excellent product is produced and the cycle time is shortened by a good melt pushing operation.
