Through grooves are provided on both sides of the middle end of the cavity 9. The partition 2 is slidably arranged inside the corresponding through groove. One end of the partition 2 is in conflict with the inner wall of the cavity 9. The thickness of the partition 2 is the same as the depth of the cavity 9, which can well block the molten metal. An inclined surface is provided at one end of the partition 2. The inclined surface has the same inclination as the side of the cavity 9 close to the through groove. A fixed shell 4 is provided on one side of the pouring shell 1. A slide plate 3 is provided on one side of the pouring shell 1.
