PROBLEM TO BE SOLVED: To prevent scoring likely to be generated by contact of the opposing faces of a plurality of molds during vertically moving the molds and during powder molding of a green compact having a biased gravity center.SOLUTION: In the opposing faces 1Na and 2Na of the adjacent molds 1N and 2N, steps 1N' and 2L with horizontal planes are provided so as to be vertically displaced. In the process of powder molding of a product having a biased gravity center, the force generating in the direction other than the vertical direction is configured to be applied to the steps 1N' and 2L even when the faces 1Na and 2Na of the molds 1N and 2N are to come into contact with each other, and the force generating in the direction other than the vertical direction, which causes scoring of the molds 1N and 2N, is dispersed to prevent scoring and a trace transferred from the scoring to the product. |
