Abstract
PURPOSE:To obtain a sinter-infiltrated metallic mold without any dispersion of dimensional variation at the time of infiltrating by using mixed powder of Fe alloy powder having the specific C content and the specific blending ratio of Cu (alloy) powder as metal powder and executing liquid phase sintering at the time of manufacturing the metallic mold after sintering and infiltrating a metal powder formed body for sintering. CONSTITUTION:The mixed powder of the Fe alloy powder containing 0.6 - 1.6wt.% C and the Cu (alloy) powder of 4 - 12wt.% blending ratio is prepared. Then, this mixed powder, organic binder of acrylic series, etc., and water or organic solvent dissolving the organic binder are mixed to make the slurry. Successively, this slurry 7 is poured into a forming mold 1 forming a reversed model 5, and the slurry 7 is pressurized 6 to discharge liquid content in the slurry 7 from slit 3 in the mold 1. Then, after releasing the powder formed body transferring the obtd. surface shape of model 5 from the mold 1, this is dried and sintered. Successively, this sintered body is put on a Cu plate and heating treatment is executed in a heating furnace, and the Cu plate is made to molten state and impregnated into voids in the sintered body to seal the porosities and solidified, and the sinter-infiltrated metallic mold having high density is obtd.
