Abstract
A powder molding apparatus comprises a mold comprising a die having a powder molding space and upper and lower punch units, and a compression driving mechanism for performing compression molding by driving the upper and lower punch units independently, wherein molded articles formed by the compression molding are held by engaging lower first and second punches serving as a formed article holding mechanism at the time of transporting the molded articles. Thus, the molded articles can be prevented from falling or shifting while being transported between stages, thereby providing a powder molding apparatus capable of high speeds.
