Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments.

[0024] Example: Refer to Figures 1 to 3 A metal powder forming device comprises a fixed seat 1 and a rotating unloading assembly. A die groove 2 is opened on the top of the fixed seat 1, and a pressing assembly is provided. The pressing assembly comprises a right-angle plate 11 fixedly connected to the top of the fixed seat 1. A second hydraulic rod 12 is fixedly connected to the top of the right-angle plate 11. The driving end of the second hydraulic rod 12 movably passes through the top of the right-angle plate 11 and is fixedly connected to a die head 13. The die head 13 is aligned with the die groove 2 and has the same size. Two right-angle rods 15 are fixedly connected to the outer wall of the die head 13. Each right-angle rod 15 is slidably inserted on the top of the fixed seat 1. When in use, metal powder is poured into the die groove 2, and then the second hydraulic rod 12 is controlled to control the die head 13 to move downward to press the metal powder in the die groove 2 into shape. Through the arrangement of the two right-angle rods 15, the die head 13 can be more stable when pressing the metal powder in the die groove 2.

[0025] The rotary unloading assembly includes a motor 3 fixedly connected to the front wall of the fixing seat 1. The motor 3 is a permanent magnet DC motor. When the power supply is stopped, the output shaft of the motor 3 can be kept in the current position to avoid loosening, thereby ensuring the stability of the device.

[0026] The output shaft end of the motor 3 is vertically upward and fixedly connected with a driving gear 4. The top of the fixed seat 1 is rotatably embedded with a first hydraulic rod 5. The outer wall of the first hydraulic rod 5 is fixedly sleeved with a driven gear 6. The driven gear 6 is meshed with the driving gear 4. The driving end of the first hydraulic rod 5 is vertically upward and fixedly connected with a connecting plate 7. The top of the connecting plate 7 is fixedly connected with a vacuum pump 8. The suction end of the vacuum pump 8 passes through the top of the connecting plate 7 and is fixedly connected with a suction cup 9. The bottom of the suction cup 9 is provided with a plurality of adsorption holes 10. After the metal powder in the die groove 2 is pressed and formed, the die head 13 is first moved out of the die groove 2, and then the motor 3 is controlled to drive the driving gear 4 to rotate, and the driving gear 4 is driven by the motor 3. The meshed driven gear 6 drives the first hydraulic rod 5 to rotate until the suction cup 9 is directly above the die groove 2, and then the first hydraulic rod 5 is controlled to drive the connecting plate 7 to move downward until the suction cup 9 is tightly attached to the surface of the formed object, and then the vacuum pump 8 is controlled to adsorb the formed object in the die groove 2 through each adsorption hole 10, and then the first hydraulic rod 5 is controlled to push the suction cup 9 to move upward until the formed object in the die groove 2 is pulled out of the die groove 2, and finally the motor 3 is controlled to make the first hydraulic rod 5 rotate together with the suction cup 9, so that the formed object after the metal powder is pressed and formed can be moved out of the fixed seat 1, and it can be taken out intact without loss, which is convenient and quick, and also has the effect of protecting the formed object.

[0027] Furthermore, a sealing ring 14 is commonly provided on the outer sides of the plurality of adsorption holes 10, and the sealing ring 14 is fixedly connected to the bottom of the suction cup 9, thereby ensuring the sealing between each adsorption hole 10 and the formed object when the suction cup 9 contacts the formed object, so that the suction cup 9 can adsorb the formed object more firmly.

[0028] The working principle of the utility model is as follows: when in use, metal powder is poured into the die groove 2, and then the second hydraulic rod 12 is controlled to control the die head 13 to move downward to press the metal powder in the die groove 2 into shape. After the metal powder in the die groove 2 is pressed into shape, the die head 13 is first moved up out of the die groove 2, and then the motor 3 is controlled to drive the driving gear 4 to rotate, and the first hydraulic rod 5 is driven to rotate through the driven gear 6 meshing therewith until the suction cup 9 is directly above the die groove 2, and then the first hydraulic rod 5 is controlled to drive the connecting plate 7 to move downward until the suction cup 9 is close to the surface of the formed object, and then the vacuum pump 8 is controlled to adsorb the formed object in the die groove 2 through each adsorption hole 10, and then the first hydraulic rod 5 is controlled to push the suction cup 9 to move upward until the formed object in the die groove 2 is pulled out of the die groove 2, and finally the motor 3 is controlled to make the first hydraulic rod 5 rotate together with the suction cup 9, so that the formed object after the metal powder is pressed and formed can be moved out of the fixed seat 1, and it can be taken out intact without loss, which is convenient and quick, and also has a protective effect on the formed object.
