[0022] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0023] Please refer to Figure 1 , Figure 2 , Figure 3 as well as Figure 4 ,in Figure 1 The main structure of the alloy powder pressing die provided by the utility model is a three-dimensional view Figure 1 ; Figure 2 for Figure 1 A schematic diagram of the enlarged structure of shown; Figure 3 The main structure of the alloy powder pressing die provided by the utility model is a three-dimensional view Figure 2 ; Figure 4 This is a top view of the mobile seat provided by the utility model.

[0024] In the specific implementation process, Figures 1 - 4 As shown, it includes a frame 1, on which an upper die 2 and a lower die 3 are installed, a plurality of punching grooves 4 are opened on the lower die 3, a plurality of punching rods corresponding to the punching grooves 4 are fixed on the upper die 2, and a ejector pin 5 is arranged between the punching grooves 4 and the frame 1.

[0025] A moving seat 6 is provided on one side of the lower die 3, and a plurality of discharge barrels 7 are penetrated on the moving seat 6. A mounting shaft 8 is movably provided inside the discharge barrel 7, and a closing plate 9 is installed on the mounting shaft 8. The plurality of mounting shafts 8 are connected by a connecting shaft 10. A plurality of limit seats 11 are fixed on the moving seat 6, and one end of one of the mounting shafts 8 penetrates the limit seat 11 and is fixed with a lever 12. A limit ring 13 is fixed on one side of the limit seat 11, and a volute spring 14 is provided inside the limit ring 13. One end of the volute spring 14 is fixed on the limit ring 13, and the other end of the volute spring 14 is fixed on the mounting shaft 8. When the device is used, the staff can add the alloy powder into the lower barrel 7 in advance. Since the closing plate 9 inside the lower barrel 7 is in a horizontal state under the action of the spiral spring 14 at this time, the alloy powder will not fall. The movable seat 6 is moved to the top of the lower die 3. At this time, the lower barrel 7 is located above the stamping groove 4. Finally, the lever 12 is pushed hard to drive the closing plate 9 to open. At this time, under the action of gravity, the alloy powder all enters the stamping groove 4 from the bottom of the lower barrel 7 to complete the loading. The loading speed is fast, and the alloy powder will hardly fall significantly during the loading process.

[0026] A pair of sliders 15 are fixed at the bottom of the movable seat 6, and a pair of slide grooves 16 are opened on the surface of the lower mold 3. The sliders 15 are slidably connected with the slide grooves 16. After the alloy powder is added, the staff only needs to slide the slider 15 at the bottom of the movable seat 6 along the slide groove 16. At this time, the lower barrel 7 is located directly above the stamping groove 4, and two storage tables 17 are symmetrically fixed on one side of the frame 1, which is convenient for the staff to place the movable seat 6.

[0027] A side seat 18 is fixed to one side of the frame 1, and a temporary storage groove 19 is opened on the side seat 18. An inclined plate 20 is arranged on one side of the temporary storage groove 19. The bottom of the inclined plate 20 is fixed to the frame 1 through a support leg. When unloading is required, the hydraulic cylinder at the bottom of the lower mold 3 can drive the lower mold 3 to move downward. At this time, the workpiece will be ejected under the action of the ejector 5. At this time, the staff uses a tool to push the workpiece into the inclined plate 20. Under the action of gravity, the workpiece will fall along the inclined plate 20 into the temporary storage groove 19 for temporary storage.

[0028] Working principle of the utility model: When the device is used, the staff can add the alloy powder into the lower barrel 7 in advance. At this time, the closing plate 9 inside the lower barrel 7 is in a horizontal state under the action of the spiral spring 14, so the alloy powder will not fall;

[0029] After adding the alloy powder, the staff only needs to slide the slider 15 at the bottom of the moving seat 6 along the slide groove 16. At this time, the lower barrel 7 is located directly above the punching groove 4. Finally, the lever 12 is pushed hard to drive the closing plate 9 to open. At this time, under the action of gravity, the alloy powder enters the punching groove 4 from the bottom of the lower barrel 7 to complete the loading. The loading speed is fast, and the alloy powder will hardly fall off during the loading process.

[0030] When it is necessary to unload the material, the hydraulic cylinder at the bottom of the lower mold 3 can drive the lower mold 3 to move downward, and the workpiece will be ejected under the action of the ejector 5. At this time, the staff uses a tool to push the workpiece into the inclined plate 20. Under the action of gravity, the workpiece will fall along the inclined plate 20 into the temporary storage tank 19 for temporary storage.
