Abstract

PURPOSE: To enable the mold which causes less breakages and deformations at the mold making to be obtained by burying the ingate parts of the extinction pattern mounted to a gate stick through the ingates with a burying material.
CONSTITUTION: After an assembly body is placed on a working table, walls 2 are built with the material which does not react with pattern and the slurry used at both side face parts of the ingates 1 at two positions on the right and left. Next, the slurry composed on ethyl silicate hydrolysis solution, gelation accelerator and refractory material powder of low thermal expansion or the slurry composed of quick- set type refractory mortar and refractory material powder of low thermal expansion is poured into the space portion 4 encircled by said walls 2 and product pattern 3. Next, the walls 2 are removed after the completion of gelation, whereby the extinction pattern assembly is obtained.
