<P>PROBLEM TO BE SOLVED: To provide a powder feeding device used in powder molding press that can minimize the possibility of unlevelled surface after leveling of molding powder, thus reducing, as small as possible, variation in the weight of each molded article due to unlevelled surfaces. <P>SOLUTION: The powder feeding device 10 used in powder molding press to feed powder into a cavity formed in a die plate 11, includes: a bottomless powder storage container 1 reciprocating over the die plate 11; and a powder surface leveling device 3 vertically slidably mounted to the powder storage container 1 such that elastic members 4 push down the leveling device to the die plate 11. The powder surface leveling device 3 has a wedge-shaped lower end portion 3a facing the powder storage container 1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
