Abstract

A method for shaping the ceramic product includes uniformly mixing the raw materials, extruding the mixture in a vacuum flexible cavity of the mould, and stripping the flexible cavity from the raw chaped ceramic product. Said mould is composed of a movable mould, a fixed mould, and a flexible cavity in the movable and fixed mould set.

Description

technical field [0001] The invention relates to a molded ceramic product, in particular to a method for forming a ceramic product and a mold thereof. Background technique [0002] At present, traditional ceramic products generally adopt the following mold forming processes: 1. After the ceramic powder is processed, it is sent into the mold cavity, and pressure is applied to make it coalesce and formed, and then the mold is opened to take out the ceramic ceramic blank; 2. 1. The ceramic slurry is injected into the cavity of the water-absorbing mold, and the mold is demoulded after receiving water, and it is formed by natural drying in the shade or forced drying by a drying treatment device; After processing, carry out natural shade drying or forced drying in a drying treatment device. [0003] The molds used in the above production methods are all rigid molds, and ceramic products are rigid products. Therefore, in terms of product modeling, in addition to the necessary funct...
