[0018] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0019] A density measuring device for powder metallurgy products, including a water tank body 1, a measuring vertical frame 2 is sleeved outside the water tank body 1, a movable support plate 3 is arranged directly above the water tank body 1, a guide groove 11 is opened near the edge of the top surface of the movable support plate 3, a slider 4 is slidably connected inside the guide groove 11, a traction clamping strip 5 is fixedly connected to the bottom of the slider 4, a push plate 6 is fixedly connected to the shorter side of the bottom of the traction clamping strip 5, a movable guide rod 7 that penetrates through the slider 4 and the traction clamping strip 5 up and down at the same time is inserted into the longer side of the bottom of the traction clamping strip 5, a defoaming puncture plate 8 with a puncture needle structure at the bottom is fixedly connected to the bottom of the movable guide rod 7, a limiting chuck 9 is fixedly connected to the top of the movable guide rod 7, a spring 10 is sleeved outside the movable guide rod 7, and a tray 16 is arranged inside the water tank body 1.

[0020] As Figure 1 and Figure 2 shown, a load-bearing support 12 is arranged at the bottom of the water tank body 1, and a measuring table body 13 is arranged at the bottom of the load-bearing support 12. This structure will facilitate the entire device to provide a stable supporting effect to the water tank body 1 through the load-bearing support 12; a front-end inclined platform 14 is fixedly connected to the left side of the measuring table body 13, and a touch panel 15 is arranged at the middle position of the inclined surface of the front-end inclined platform 14. The touch panel 15 is arranged in an inclined structure. This structure will facilitate the operator to conveniently debug the panel information displayed on the touch panel 15; the movable support plate 3 is arranged at the upper position inside the measuring vertical frame 2, and the movable support plate 3 and the measuring vertical frame 2 are rotatably connected. A groove 17 with a gradually concave structure is opened at the middle position of the top surface of the movable support plate 3. When a weighing operation is performed through the movable support plate 3, the gradually concave structure of the groove 17 can make the placement operation of the measured powder metallurgy product more centered.

[0021] As Figure 1 , Figure 2 and Figure 3As shown, the inner surfaces of the water tank body 1 are respectively attached to the front and rear end faces of the push plate 6 and the defoaming puncture plate 8.
