ceramic mold

Abstract

The invention belongs to the technical field of ceramic production and processing, and specifically relates to a ceramic mold, which includes an annular mold cover made of elastic material, and a top plate and a bottom plate respectively located at the upper and lower ends of the annular mold cover; the bottom plate is provided with an inflatable unit, and the The inflatable unit includes an air channel opened inside the bottom plate and an air inlet and an air outlet provided at both ends of the air channel; the air outlet is provided with a movable block, and the movable block is assembled to be able to move between the following two stations: Switching: station 1, the movable plug is blocked on the air outlet and used as a part of the inner wall of the cavity; station 2, the movable plug is removed from the gas outlet to communicate the air passage with the cavity. The ceramic mold of the present invention can be filled with high-pressure gas from the bottom, and the gas filling pipeline can realize automatic opening and closing, thereby ensuring the molding quality of the mold, simplifying the mold filling operation process, and improving production efficiency.

Description

technical field [0001] The invention belongs to the technical field of ceramic production and processing, and in particular relates to a ceramic mold. Background technique [0002] The mass production of ceramic utensils is mainly made by mold molding, and the mold molding process mainly includes two realization methods: mud molding and dry powder molding. These two molding methods will produce different degrees of friction between the green body and the inner wall of the cavity when demoulding. Adhesion is not conducive to demoulding. Therefore, in the prior art, the interior of the mold is manually inflated and pressurized to fully separate the green body from the inner wall of the cavity, and then the demoulding is performed. However, this manual operation is time-consuming and laborious, and the production efficiency is not high. , it is difficult to meet the needs of mass production. Contents of the invention [0003] The object of the present invention is to provide...
