摘要
Herein disclosed is a method of making a porous mold by using an upper case which bears lines for forming channels for water and air communications. The method of making a porous mold includes attaching holding members in an array at a desired interval to an upper case made of a rigid material such that they project a predetermined distance from the inner surface of said upper case; removably attaching flexible lines to said holding members; passing at least one end of each of said flexible lines through said upper case to the outside of said upper case; casting slurry into a molding cavity which is defined by said upper case and a base joined to the former case to form a porous mold; removing said upper case together with said holding members from the porous mold after said slurry has cured so that said holding members are disengaged from said flexible lines to leave the latter in said porous mold; filling up the holes, which are left in the porous mold at the traces of said holding members, with a resin; and pulling said flexible lines out of the porous mold to form channels in said porous mold after said resin has cured.
