The utility model relates to an air pressure difference suction vacuum device used for forming dies. High pressure gas is introduced in from a rear bolted connection pipe fitting of an air pressure difference generating device, and quickly flows through inner holes of a plurality of air guide cavities, a front bolted connection pipe fitting and a plurality of exhaust pipes to be blown and discharged. When the high pressure air is injected through the inner holes of the plurality of air guide cavities, each suction channel consequently generates air pressure difference suction force to sequentially suck out the air and residues in a pressure casting forming die or plastic forming die through the inner holes of a plurality of suction guide pipes, the inner holes of an auxiliary body, the filtration material of a filter and a wide channel, a narrow channel and a wide channel of an air exhaust assembly, so that a vacuum die cavity is obtained to achieve the further effect of rapidly injecting precision parts for
