[0028] A pushing member 6 is installed at the lower end of the sliding member 3.
[0029] Please refer to the attached Figure 3 , Figure 5 , the upper die module 1 includes an upper die base 11 and an upper die 12, the upper die 12 and the lower die 42 are respectively detachably installed on the upper die base 11 and the lower die base 41 through bolts, a plurality of fixed ears 21 are installed on the outer sides of the upper die base 11 and the lower die base 41, and the fixed ears 21 are provided with fixed holes 22.
[0030] In this embodiment, the upper die module 1 and the lower die module 4 mounting base can be fixed on the pressing equipment and the platform through the fixed holes 22 using bolts, and the upper die 12 and the lower die 42 can be disassembled by bolts to replace the mold according to production requirements.
[0031] Please refer to the attachedFigure 1 , Figure 3 , the sliding member 3 includes a guide plate 31 and a sliding rod 32 with a handle. The sliding rod 32 penetrates the guide plate 31 and is movably connected to the guide plate 31. The sliding rod 32 is fixedly connected to the lower die base 41. Specifically, by pushing and pulling the sliding rod 32 through the handle on the sliding rod 32, the lower die 42 can be driven to slide.
[0032] Please refer to the attached Figure 1 , Figure 6 , the pushing member 6 includes a fixing plate 61 fixed to the bottom of the sliding rod 32. A shovel plate 62 is installed at the front end of the fixing plate 61. Arc-shaped guiding parts 63 are installed at both ends of the shovel plate 62. A shovel knife 64 is installed at the front end of the shovel plate 62. The shovel knife 64 cooperates with the recovery groove 23. Specifically, the shovel knife 64 can move along with the sliding of the sliding rod 32. After scraping off the excess metal powder on the lower die 42 at the inlet and outlet 25, the metal powder flying over the recovery groove 23 can be shoveled into the recovery groove 23 by the shovel knife 64. Embodiment 2
[0033] Based on the above Embodiment 1, please refer to the attached Figure 2 , Figure 6 , the recovery member 5 includes a recovery box 51. The recovery box 51 is placed in the recovery groove 23 and fits with the recovery groove 23. Holding handles 53 are symmetrically installed at both ends of the recovery box 51. Activity grooves 52 for the holding handles 53 to move are symmetrically provided at both ends of the recovery groove 23.
[0034] In this embodiment, the metal powder entering the recovery groove 23 will be collected by the recovery box 51. After collecting a certain amount of metal powder, the recovery box 51 can be conveniently taken out through the holding handles 53 so as to take out the recovered metal powder for secondary utilization.
[0035] Working principle and usage process of the utility model: Before pressing, slide the lower die 42 outside the shielding box 24. After filling the lower die 42 with metal powder, control the movement of the lower die 42 towards the shielding box 24 by means of the handle on the sliding rod 32. When the lower die 42 passes through the inlet and outlet 25, the upper end of the inlet and outlet 25 will scrape off the excess and piled-up metal powder in the upper die 12 and fall into the recycling box 51 in the recycling tank 23. When the sliding speed of the lower die 42 is too fast, some metal powder will fly over the recycling tank 23 and land on the mounting seat of the lower die 42. At this time, as the sliding rod 32 slides, the scraper plate 62 below the sliding rod 32 drives the scraper 64 to shovel the metal powder on the mounting seat of the lower die 42 into the recycling box 51 in the recycling tank 23. When the metal powder in the recycling box 51 is about to overflow, hold the holding handle 53 with both hands to lift the recycling box 51 out of the recycling tank 23 for secondary utilization of the metal powder. After the lower die 42 slides completely into the shielding box 24, the pressing equipment can be driven to drive the upper die 12 to press down for pressing. After pressing is completed and the product is taken out, slide the lower die 42 out of the shielding box 24 again, pour in the metal powder again, and the pressing operation can be carried out continuously according to the above steps.
