The
powder metallurgy die
assembly comprises a
machine tool, a
dust collector, an air cylinder and an ejector head, telescopic plates are slidably connected to the portions, on the side edges of the two sides of the ejector head, of the
machine tool, scraping plates are arranged at the output ends of the telescopic plates, inclined plates are arranged on the scraping plates, shifting wheels are arranged above the inclined plates, the shifting wheels are connected with linkage rods
through transmission belts, and the linkage rods are connected with the
dust collector. The linkage rod is arranged on the gear, the gear is connected to the rack in a meshed mode, in the
machining process, the ejector head can be driven by the air cylinder to move, when the ejector head moves upwards, the ejector plate can be driven to move upwards, the ejector plate can push the rotating rod, the rotating rod can push the push rod, and the push rod can drive the telescopic plate to move towards the position of a
machine tool. And in the moving process of the telescopic plate, the gear can rotate, the linkage rod can drive the shifting wheel to rotate through the
transmission belt, and therefore the
powder is pushed to the inclined plate and the air opening through rotation of the shifting wheel, and the
powder is conveniently collected.
