ABSTRACT:
A porous mold for manufacturing ceramics comprises a porous mold body including a mold central portion and a mold outer peripheral portion and having mold surface of a shape corresponding to an outer shape of a suspension insulator and other similar ceramics to be manufactured having a small diameter hollow cylindrical central core portion with a closed head portion and a large diameter shed portion extended from the core portion in a radial direction, wherein water absorption percentage of a mold surface side portion of the mold outer peripheral portion is larger than that of the mold central portion. The water absorption percentage of the mold surface side portion of the mold outer peripheral is 20-30%, and that of a mold head portion of the mold central portion is 10-20%. A difference of the water absorption percentage between the mold surface side portion of the mold outer peripheral portion and the mold head portion is 5-20%.
