The invention discloses an automatic ceramic slip casting system. The automatic ceramic slip casting system comprises a conveying device, a slip casting device, a pulp pouring device and a mold opening and blank taking device which are arranged on a machine base. Multiple mold clamps circularly move on a conveying channel, and the slip casting device carries out slip casting on molds. The mold clamps obtained after slip casting is carried out are conveyed into a slip casting drying room to be dried, and then the mold opening and blank taking device turns over the mold clamps through a turnovermechanism, so that the molds are turned over to pour out pulp in blanks. The mold clamps are rotated to the original state through a rotating mechanism and then conveyed to a blank taking drying roomto be dried. The molds are opened by the mold opening and blank taking device by means of a mold opening mechanism, and the blanks are taken out of the mold clamps through a blank taking mechanism. The mold clamps are conveyed into a mold drying room, and then enter the slip casting device to be subjected to slip casting, and circular operation is carried out in this way. Therefore, automatic production of ceramic slip casting can be achieved, the labor intensity of manpower is reduced, and the production efficiency is improved. The automatic ceramic slip casting system is used for slip casting processing of ceramic.
