Slip casting process for closestool blank and slip casting device

Abstract

The invention provides a slip casting process for a closestool blank. The slip casting process comprises the following steps of conducting low-pressure slip casting in a die cavity locked by die closing, and keeping natural gas paths of the die cavity and the die walls of a left die, a right die, a rear die, an upper die and a lower die open in the low-pressure slip casting process; after low-pressure slip casting is finished, closing the natural gas path of the die cavity; conducting high-pressure slip casting in the die cavity, and keeping natural gas paths of the die walls of the left die,the right die, the rear die, the upper die and the lower die open in the high-pressure slip casting process; after high-pressure slip casting is finished, closing the natural gas paths of the die walls of the left die, the right die, the rear die, the upper die and the lower die; opening a blowing air path and a slurry discharging pipeline of the die cavity for blowing and discharging slurry; after slurry discharging is finished, closing the blowing air path and the slurry discharging pipeline while opening a consolidation air path for consolidation; and after consolidation is finished, closing the consolidation air path, and closing the natural gas path of the die cavity after instant opening. According to the slip casting process for the closestool blank and the slip casting device, a die closing and opening method can be well matched to achieve rapid slip casting of the closestool blank, and the production efficiency and quality of products are improved.

Description

technical field [0001] The toilet grouting forming technology of the present invention particularly relates to a grouting forming process of a toilet embryo body. Background technique [0002] At present, the toilet has become an indispensable daily device in people's life. The production of its blank parts has problems of low efficiency, low yield and high cost. One of the main reasons is the grouting mold, which is divided into upper and lower molds. structure, large size, poor operability, especially the poor operability of mold removal, and the manual operation in the mold closing operation not only consumes a lot of manual labor, but also has low production efficiency, and the accuracy of manual operation cannot be guaranteed, resulting in defective products. The high rate will greatly affect the economic benefits of production. [0003] In view of this, the inventor of this case conducted in-depth research on the above problems, and applied for and disclosed a mold cl...
