The invention discloses a press for high-speed pressing of powder metallurgy on the basis of mechanical spring energy storage. The press comprises a press body frame, a heavy hammer lifting mechanism, a heavy hammer impact mechanism, a hammer handle locking and releasing mechanism, a mechanical spring, a suspension part thereof, a spring sleeve, a fastener thereof, an upper die punching and supporting table and a power mechanism, wherein the heavy hammer lifting mechanism sliding along a straight line, the hammer handle locking and releasing mechanism, the heavy hammer impact mechanism and the upper die punching and supporting table are successively connected on a guide rod in series; in the direction vertical to the guide rod, two ends of a shaft pin type sensor pass through and are clamped into the through holes of a suspension part frame; and the middle part passes through to be clamped in a hanger through hole. The high-speed press for powder metallurgy of the invention is suitable for producing powder metallurgy high-speed pressing parts with smaller volume, has small volume, small weight, simple structure, convenient assembly and reliable performance, overcomes the problems of complex structure and high manufacturing cost of the existing hydraulic high-speed pressing equipment, and is easy to popularize and apply in the powder metallurgy industry.
