A slip casting device has a molding station for molding a casting with a mold, and a releasing station separate from the molding station, for separating the casting from mold members of the mold which carry the casting. The device may include a pair of vertically spaced molds and a common clamping cylinder interposed between the pair of molds.

Slip casting device

A pressure slip casing apparatus for producing a sanitary ware such as a toilet bowl, comprises lifting hydraulic cylinder means secured to said top member of a stationary frame; a pair of suspending devices supported by a base plate attached to said lifting hydraulic cylinder means; an interlocking mechanism for operatively connecting said suspending devices to each other; and a hydraulic cylinder device for moving a suspending devices towards and away from each other through the action of said interlocking mechanism. A mold part and a core mold part are attached to said base of said stationary frame and to the lower surface of said base plate, respectively. Side mold parts are suspended by said suspending devices so as to be brought and aligned together when said suspending devices are moved towards each other, and said core mold part and said side mold parts in assembled state are adapted to be lowered by said lifting hydraulic cylinder means so that said side mold parts and said core mold parts are sequentially assembled with said bottom mold part and then clamped therewith.

Pressure slip casting apparatus for producing sanitary ware

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.
