Problems solved by technology

[0003] However, the gypsum mold has the following defects: (1), the strength, water resistance, wear resistance and corrosion resistance of the gypsum mold are poor, and the gypsum is slightly soluble in water, and its own water resistance is poor and it has been in a humid and complex mud environment for a long time. The deterioration of the mold performance leads to a very short service life of the plaster mold, generally only 30-50 times, and the longest is no more than 70 times
(2) Due to the short service life of the above-mentioned plaster molds, waste plaster molds are often piled up in the production process, occupying the factory area requires a large place to place them
Cleaning up waste gypsum molds requires a lot of manpower and financial resources for the factory, and what is more serious is that waste gypsum molds have a great impact on the environment
(3) Using existing gypsum molds, only rough pottery blanks can be obtained, and further finishing of rough blanks is required to obtain qualified finished products; resulting in low product qualification rate and low production efficiency
(4) The weight of the existing plaster molds often exceeds 100 catties. Due to the excessive labor intensity in the molding process of the green body, it is difficult to recruit molding employees, which greatly restricts the development of the factory
(5) Due to mass production, plaster molds cannot produce S-shaped special-shaped products at one time

Abstract

The invention belongs to the technical field of ceramic forming and particularly discloses a manufacturing process for a ceramic forming aluminum alloy mold and a use method thereof. The surface of the aluminum alloy mold is subjected to special treatment to enable contact performance between the surface of the mold and a clay blank to be similar to that of a gypsum mold. The mold can replace the gypsum mold and is used for ceramic forming, pollution of ceramic waste to the environment is reduced, forming labor intensity can be relieved, production cost is reduced, the blank forming quality is improved, and special-shaped product development and new product development and upgrading are facilitated.

Description

technical field [0001] The invention belongs to the technical field of ceramic molding, and in particular relates to a manufacturing process of an aluminum alloy mold for ceramic molding and a use method thereof. Background technique [0002] The grouting molding method and the rolling molding method are commonly used molding methods in the large-scale production of ceramics. The molding method is mainly carried out through the plaster mold. The capillary force of the pores in the plaster mold absorbs the excess water in the ceramic slurry to make the slurry adhere to the mold in a dispersed manner, forming a mud layer with the same shape as the mold. Extend and gradually thicken. When the thickness of the mud layer reaches the requirement, pour out the excess slurry, and separate from the gypsum mold wall after drying and shrinkage, and the pottery body is made. [0003] However, the gypsum mold has the following defects: (1), the strength, water resistance, wear resistanc...
