AI Technical Summary

Technical Problem

In the existing toilet grouting process, the outlet of the slurry delivery pipe is designed as a closed structure, which causes enclosed air to be trapped and form bubbles when the slurry flows. After the pressure dissipates, the bubbles enter the molding cavity, causing surface bubble defects and affecting the appearance and quality of the product.

Method used

A double-tube grouting system is used, including a slurry delivery pipe and a bent second grouting pipe, which is connected to the slurry delivery pipe to avoid bubbles forming excess space in front of the slurry entry direction, ensuring that bubbles do not enter the molding cavity.

Benefits of technology

It effectively reduces the bubble defects on the surface of the toilet body, improves product quality and production efficiency, and shortens the grouting time.

Description

Technical Field

[0001] The utility model relates to the field of sanitary ceramic production, in particular to a mould for reducing bubbles in toilet grouting. Background Art

[0002] Existing toilet products are usually formed by grouting. The conventional production process is: the prepared mud is injected into the molding cavity of the mold through the grouting pipe and the grouting pipe. After that, the mud is formed in the mold. After the toilet blank in the mold is formed, the remaining mud in the molding cavity is drained away through the grouting pipe and the grouting pipe. After that, the mold is opened and the toilet blank is taken out. Finally, unplug the Figure 2 The end cap 7 at the front end of the slurry delivery pipe is used to clean the grouting pipe and the slurry delivery pipe.

[0003] like Figure 2 During the grouting process, since the outlet of the slurry delivery pipe is designed as a closed structure, a cecal space 9 is formed at the front end where the slurry flows. This cecal space 9 contains enclosed air. Due to the flow of slurry, the enclosed air is temporarily trapped under high pressure to form bubbles 8. When the grouting operation stops, the pressure in the cecal space 9 gradually dissipates. At this time, the bubbles 8 that were originally suppressed by the pressure will lose their restraints and gradually move into the molding cavity, and may eventually float on the surface of the formed toilet blank. Such surface bubbles cannot be eliminated in the subsequent firing process, resulting in obvious bubble defects on the surface of the product, which not only affects the appearance, but may also reduce the overall quality and service life of the product.
