The gist of the present invention is to provide a detour in which the air bubbles in the slurry can be removed by injecting the bubbles in the slurry into the casting port of the slurry in the mold for molding sanitary ware by pressure casting the slurry. That is, a split mold is provided.

When the slurry flows, the air bubbles attach to the wall of the detour together with the slurry, so that the air bubbles are not mixed into the mold and a product without pinholes can be formed.

FIG. 1 is an enlarged sectional view of a main part around a casting opening of a lower mold of a pressure casting mold 1, and FIG. 2 is a plan view of a split mold. In the figure, a lower mold 2 constituting a pressure casting mold 1 is made of gypsum, and a PVC pipe 4 opening downward is attached to the lower surface of the lower mold 2.
Is connected to a hose 5, through which the pressure is applied from the outside and the slurry is poured.

Formed walls 9a and 9b forming an angle of about 90 ° are formed in the detour R, and the slurry press-fitted from the PVC pipe 4 first collides with the formed walls 9a and 9b, On the walls 9a and 9b, the bubbles in the slurry are deposited together with the slurry, and only the slurry from which the bubbles have been removed is injected into the mold through the PVC pipe 8.

きる。The PVC pipe 8 is located closer to the tip of the inlaid wall 9a.
If the lower end of the is protruded downward, a bypass R that removes bubbles more effectively is formed. Therefore, since bubbles in the slurry are deposited on the inlaid walls 9a and 9b, the mold is removed after the sanitary ware is formed, and then the split mold 6 is removed from the lower mold 2, and the inlaid walls 9a and 9b are inlaid. Remove the mud and split again 6
Can be mounted on the casting opening 3 of the lower mold 2 and reused. The split mold 6 can also be formed of gypsum.
