Abstract

PURPOSE:To manufacture quickly and easily a prescribed metallic pattern in the manufacture of the metallic pattern having a prescribed thickness with a base part by manufacturing a reproduction mold of a refractory material with the mold coated with a soft material of a master mold, coating the paraffin shaped to the metallic pattern having the prescribed thickness to said mold, calcining and templating the paraffin in the refractory material, pouring a molten metal therein and forming the metallic pattern. CONSTITUTION:The soft material such as silicon rubber is coated to the split master mold and is templated, then the refractory material is packed fully therein to manufacture the reproduction mold. The paraffin shaped to the metallic pattern having the prescribed thickness is coated to such reproduction pattern to form lost wax. The lost wax is embedded into the refractory material and is calcined to form a casting mold for the metallic pattern. The molten metal of a cobalt alloy, etc. is poured into the casting mold made of the refractory material to manufacture the metallic pattern having the prescribed thickness. The prescribed split metallic pattern is obtd. when a low melting alloy is poured to the rear of such metallic pattern and is solidified. The metallic pattern having the prescribed thickness is quickly and easily manufactured by the above-mentioned method.
