Metal powder metallurgy injection molding die

The utility model discloses a metal powder metallurgy injection molding die which comprises a cooling tank, and an electric push rod is fixedly connected to the inner side wall of the cooling tank. A placing plate is fixedly connected to the top of the electric push rod, and the placing plate is located in the cooling tank; mounting plates are fixedly connected to the two sides of the cooling tank; a bearing seat is mounted at the top of the mounting plate; pulling ropes are pulled, so that the pulling ropes generate pulling force to pull transparent sealing cover plates hinged to the two sides of the cooling tank through bearing pedestal torsion springs to cover the top of the cooling tank, the transparent sealing cover plates and the cooling tank are combined for sealing, then water is guided in through a water inlet pipe, the mold is subjected to rapid surrounding heat dissipation treatment through the water, and water mist generated in the water circulation process is discharged through a water outlet pip
