1. A powder dry-pressing molding device, comprising a rack, wherein the rack is provided with a first pressure mechanism, a workbench mechanism and a second pressure mechanism in sequence along an up-and-down direction, and one side of the workbench mechanism is provided with a scraping mechanism;
the first pressure mechanism comprises an upper slide block capable of moving up and down, the upper slide block is connected with an upper driving mechanism, and an upper punch is disposed at a bottom of the upper slide block;
the workbench mechanism comprises a middle mold seat, a workbench is fixed above the middle mold seat, a middle mold is disposed inside the middle mold seat, a mandrel fixedly disposed coaxially with the middle mold runs through the inside of the middle mold, and a compacting space for containing powder is formed between the mandrel and the middle mold;
the second pressure mechanism comprises a lower slide block capable of moving up and down, the lower slide block is connected with a lower driving mechanism, a lower punch is fixed at a top end of the lower slide block, and the lower punch is capable of extending into the compacting space between the mandrel and the middle mold and compacting the powder together with the upper punch; and
the scraping mechanism comprises a pusher connected with a scraping driving mechanism and capable of moving along the workbench, the pusher is provided with a feeding channel capable of being communicated with the compacting space, the feeding channel is capable of being communicated with a barrel disposed on the rack, and after the feeding channel is aligned with the compacting space, the lower punch moves downward to generate a vacuum so as to suck the powder into the compacting space.
