Abstract
PURPOSE: To produce the casting mold having large reverse grades in wall thickness with simple process and low cost by placing an insert of hollow rubber-base pattern and packing casting sand then setting the casting sand by microwaves and withdrawing the insert and rubber-base pattern.
CONSTITUTION: Insert 3 such as silica sand or the like is inserted in a hollow rubber-base pattern 2 of large reverse grades in wall thickness and a cover 4 is provided. Water-base special coat 5 is coated on the surface of the rubber-base pattern 2. The coating agent comprising mixing silica powder #300, 100 parts, water-soluble resol resin 10 parts and water 60 parts is used. Next, the rubber-base pattern 2 is covered with a frame 6 and the casting sand 7 (resin coated sand) containing thermosetting resins and dielectric material for microwaves, Fe3O4 is poured and packed in the inside. Microwaves are radiated to allow the casting sand and coat layer 5 set through self evolution of heat. After setting, the insert 3 then rubber-base pattern 2 are drawn out and this yields the casting mold.
