Problems solved by technology

[0004] However, the plaster mold has the following defects: (1), the strength, water resistance, wear resistance and corrosion resistance of the plaster 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 complicated 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 to 50 times, and the longest is no more than 70 times
(2) Due to the short life of the above-mentioned plaster molds, the waste plaster molds are often piled up in the production process, occupying the factory area and requiring 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) Utilize existing gypsum mold to form, can only get rough pottery billet, also need to carry out further fine processing to rough billet, just can obtain qualified finished product; Lead to the product qualified rate is low, and production efficiency is low
(4) The weight of the existing gypsum 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 and an application method of an aluminum alloy mold for ceramic forming. The surfaceof 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 is capableof replacing the gypsum mold and used for ceramic forming, pollution of ceramic waste to the environment is reduced, the forming labor intensity can be reduced, the production cost is saved, and theblank forming quality is improved; and special-shaped product development and new product development and upgrading are facilitated.

Description

[0001] This application is a divisional application with application date: March 21, 2017, application number: 201710168002.5, name of invention: manufacturing process of aluminum alloy mold for ceramic molding and its use method, and the applicant is Liling Xiangcheng Ceramic Manufacturing Co., Ltd. technical field [0002] 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 [0003] 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 thic...
