Porous ceramic membrane preparation mold and method

The invention discloses a mold for preparing a porous ceramic membrane. The mold includes an accommodating cavity, a pressing head, and pressing rods used for placing in the channels of a porous ceramic membrane; the accommodating cavity is provided with a molding cavity; the side wall of the molding cavity is a unidirectional permeable membrane, and the permeable direction is from the accommodating cavity to the molding cavity; the internals of the pressing rods are hollow, one end of each pressing rod communicates with the inner cavity of the pressing head, and the side wall of each pressingrod id distributed with small holes or is a mesh shape; and the pressing head is provided with an inlet used for introducing liquid in the pressing head, and the liquid can flow out from the side walls of the pressing rods. Through the adoption of the pressing rods whose side walls have holes, a pressing rod liquid and an accommodating cavity liquid can be controlled to make a mixed liquid solidified to form a green body
