Description
Technical Field

Background
The ceramic is made up by using natural clay and various natural minerals as main raw materials and making them pass through such processes of pulverizing, mixing, forming and calcining.
In the ceramic production industry, plaster molds are the most used traditional slip casting molds, such as the molding of sanitary ceramics, household ceramics, special ceramics with complex shape and structure, and the like. Compared with other grouting forming molds made of other materials, the gypsum mold has the advantages of rich raw material sources, low price, simple manufacturing process, high water absorption, good dimensional stability and the like.
The traditional plaster mold is split and generally comprises a bottom mold and two half molds, wherein the bottom mold is manufactured according to a female mold, a first half mold is manufactured according to the bottom mold and the female mold, and a second half mold is manufactured according to the first half mold and the female mold. As can be seen from the above process, before the first mold half is manufactured, it is necessary to wait for the mold bottom to be formed and hardened before the second mold half is manufactured, and it is necessary to wait for the first mold half to be formed and hardened before the second mold half is manufactured. Because of the long waiting time, in order to realize the streamlined production in the traditional industry, the conventional method is to use a barrel of gypsum raw material to perform grouting to form a bottom mold, then use a second barrel of raw material to perform grouting to form a first half mold, and finally use a third barrel of raw material to perform grouting to form a second half mold. The problem that exists in this way is that it is difficult to ensure that three barrels of gypsum raw materials have the same solidification expansion rate, which results in that the joint between the bottom mold and the two half molds after molding cannot be flush, which results in dislocation of joint lines, and further results in uneven surface of the finally prepared ceramic.
