ABSTRACT:
An apparatus for pressure molding ceramic articles includes at least one split mold including a core mold and an outer mold which are joined together for defining a pressure mold cavity therebetween. At least the bottom surface of the pressure mold cavity is inclined longitudinally and laterally, while the split mold per se is not inclined and the slip supply passage for supplying the slip into the pressure mold cavity communicates with the lowermost end of the pressure mold cavity. Due to the above construction, it is no longer necessary to incline the entirety of the split molds so that the frame structure of the apparatus can be vertically constructed on a horizontal floor which permits easy construction installation and adjustment and maintenance of the apparatus. Furthermore, since the bottom surface of the pressure mold cavity is inclined longitudinally and laterally, the surplus slip is discharged completely and smoothly, and does not remain in the pressure mold cavity. Accordingly, molded articles of high-quality and uniform thickness can be obtained.
