A kind of manufacturing method of large and medium-sized pottery

Abstract

The invention discloses a large and medium chinaware manufacturing method. Compared with a traditional method, such subsequent treatment processes as outer surface finishing, finish carving treatmentand / or colored drawing treatment and glazing of large and medium chinaware ceramic blanks and production of chinaware outer profile surfaces belong to simultaneous asynchronous treatment spaced by specific space-time intervals, so that the problem of performing subsequent processes one by one after completion of previous treatment procedures in the traditional method is overcome, and saving of a lot of time and delication of the artistic effect can be both considered. In addition, the method can finish complex shapes, is more suitable for manufacturing of large and medium artistic shape chinaware, meanwhile, greatly enriches the shaping range of large and medium chinaware, and greatly reduces the manufacturing cost of large artistic porcelains.

Description

technical field [0001] The invention relates to the technical field of ceramic molding, and more specifically, relates to a method for manufacturing large and medium-sized ceramic wares. Background technique [0002] There are many methods for forming ceramics, and the mature methods used in mass production include artificial drawing method, roll forming method, grouting method, high pressure grouting method, dry powder pressing method and other production methods. Dry powder compression molding is only suitable for the production of plate-shaped ceramic products; roll forming is suitable for the production of small circular cross-section products, and has special requirements for the maximum and minimum cross-sectional diameter of the product; high-pressure grouting molding can be mass-produced quickly For complex ceramic components with specific shapes, the product size is limited by the strength of the porcelain parts, mold material, complexity and processing size, and ca...

Problems solved by technology

Dry powder compression molding is only suitable for the production of plate-shaped ceramic products; roll forming is suitable for the production of small circular cross-section products, and has special requirements for the maximum and minimum cross-sectional diameter of the product; high-pressure grouting molding can be mass-produced quickly For complex ceramic components with specific shapes, the product size is limited by the strength of the porcelain parts, mold material, complexity and processing size, and cannot be used to produce large-sized and complex ceramic parts; the grouting molding method is limited by the strength of the plaster mold and the demoulding process. It can only be used for the molding of medium-sized ceramic parts. At the same time, in order to ensure the release of the internal stress of the ceramic blank, the water absorption speed of the plaster mold must be strictly controlled, resulting in a relatively long molding time for the plaster mold, and the number of molds required for mass production is relatively small. Plaster molds also have problems such as complex structure, short life, high mold cost, and many wastes, which cause the cost of this molding method to rise; the manual casting method is convenient and flexible, and can produce various sizes and molds. The disadvantage of exquisite porcelain blanks is that the quality of the product is greatly affected by subjective factors based on the "skill" level of the master worker. At the same time, the production environment is harsh, the labor intensity is high, the efficiency is low, and the cost per piece is high.

[0003] Due to the above reasons, the production of large-sized and high-height ceramic devices, such as large decorative vases, large vases, large utensils, and large porcelain columns with a height of more than one meter, still relies on manual production and requires experienced craftsmen. After segmenting the porcelain to be formed and partially semi-mechanized drawing, these formed parts are manually butted; even so, the yield or the aesthetics and artistic level of the finished product will be greatly affected

At the same time, the quality, output and price of the popular fancy shapes, personalized shapes or large-scale ceramics with sculptural effects in the market at the current stage are also greatly affected due to the same reason, resulting in the current ceramics industry being completely unable to meet the needs of the
