Abstract

PURPOSE: To prevent adverse influence owing to the residues of an investment casting patterns by forming a coating layer on the outside circumference of the noninvestment casting pattern then dividing and rapping these, restoring the same, applying coating again and forming a mold.
CONSTITUTION: First, a noninvestment casting pattern 1 of a desired shape formed of a suitable material is subjected to repetition of coating and sanding by using refractory slurries and dry sand alternately and is molded, whereby a ceramic shell mold 2 of suitable thickness is formed. Upon drying of the mold 2, it is cut in the position of the continuous line connecting, for example, a-b-c-d-e-f, to bisect the mold 2 to the right and left, and the pattern 1 is rapped. Then, the divided plural ceramic shell pieces are joined again to the original state, by which they are joined and integrated. Coating and sanding are repeated on the outside surface after the integration to perform molding, whereby the ceramic shell mold formed into one body is completed.
