Disclosed is a powder metallurgy mold wherein a firm combination state between assembled parts can be maintained as an inner mold having a tapered wall surface is fixated as indented in a tapered space of an outer mold, and the mold not easily broken having a very long lifetime as the inner mold is occasionally mounted inside the outer mold as divided. The powder metallurgy mold comprises: an outer mold having an inner mold combining part formed with a tapered space which becomes narrower in a vertical direction; and an inner mold including a tapered outer wall surface corresponding to the tapered space to be indented and combined with the inner mold combining part, and providing an inner space which is required to mold a product to the inside of the outer wall surface. |
