Abstract
A forming mold for making ceramics having a pattern includes a first mold made of a water-permeable material and including a first press face, a second mold made of a water-permeable material and including a second press face, and a third mold made of a water non-permeable material and disposed between the first and second molds. The third mold has a third press face in contact with the first press face, and a patterned face opposite to the third press face and cooperating with the second press face to confine a forming space.
Claims11
A forming mold for making ceramics having a pattern, comprising:
- a first mold made of a water-permeable material and including a bottom end face recessed to form a first press face, and a top end face opposite to said bottom end face;
- a second mold made of a water-permeable material and including a second press face;
- and
- a third mold made of a water non-permeable material and disposed between said first and second molds, said third mold having a third press face in contact with said first press face, and a patterned face opposite to said third press face and cooperating with said second press face to confine a forming space;
- wherein each of said first and second molds is made of gypsum, and said third mold is made of plastic;
- wherein said first mold further includes a feed inlet communicating with said forming space, said feed inlet including a large diameter outer section extending through said top end face and adapted to receive a predetermined amount of a ceramic slurry, and a small diameter inner section connected to said large diameter outer section and extending through said first press face;
- and
- wherein said third mold includes a substantially bowl-shaped portion disposed between said first and second press faces and having said third press face and said patterned face, and a tubular portion that extends upwardly from said bowl-shaped portion into said small diameter inner section and that communicates with said forming space and said large diameter outer section.
