Description

Gypsum mould forming device

Technical Field

The utility model belongs to the technical field of the gypsum mould preparation and specifically relates to indicate a forming device of gypsum mould.

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.
