Powder injection molding die for lightweight structural part

The utility model discloses a light-weight structural part powder injection molding die which comprises a fixed die and a movable die, a male die is arranged in the middle of the side, facing the movable die, of the fixed die, a female die matched with the male die is arranged in the middle of the side, facing the fixed die, of the movable die, and a glue inlet is formed in the middle of the female die. A connecting material for filling the cavity to prevent sintering deformation is arranged in the cavity in the middle of the structural part, and the center of the connecting material corresponds to the center of the female die. According to the mold, the conical glue inlet is adopted, the size of the lower end of the glue inlet is increased, meanwhile, the glue inlet is formed in the center of a structural part, the structure of the position of the glue inlet of a product is optimized, and the problems of insufficient filling, weld marks, black lines and the like are effectively solved; a connecting material
