This invention discloses a method and rapid verification device for improving the one-time molding rate of large-size NdFeB products. The method includes: taking a selected amount of alloy powder, simulating the formal molding process in the rapid verification device, acquiring pressure-displacement data in real time during the molding process, and plotting a pressure-displacement curve; comparing the pressure-displacement curves of alloy powders with different powder state parameters when reaching the same compaction density, and selecting the powder state parameter with the most stable curve shape and the required molding pressure to reach that compaction density within a preset optimal range as the optimal powder state parameter; based on the optimal powder state parameter, producing large-size NdFeB green blanks in a formal production mold. This invention can efficiently screen out the optimal powder state parameters required for molding before inputting into the formal mold, significantly shortening the molding press debugging cycle, reducing trial and error costs, and significantly improving the one-time molding rate of large-size NdFeB products.
