[0003] Currently, the material cylinder of metal powder forming machines is generally installed on the outside of the forming machine body using an additional bracket. This split structure occupies a large space. Furthermore, for powder forming machines with a fixed lower mold and a movable lifting platform, the cylinder of the feeding mechanism is currently connected to the lifting platform via an additional extension frame to complete the cylinder installation. This structure increases the difficulty of mechanical assembly, and the bottom of the additionally installed extension frame is generally unsupported. As it moves up and down with the lifting platform, the stability of the cylinder decreases. Therefore, there is an urgent need for an improved technology to solve this problem in the existing technology. Utility Model Content

[0023] Please see Figure 1-2 This utility model provides a technical solution: a metal powder forming machine, including a frame, an upper mold 6, a lifting platform 8, a lower mold 14, a feeding mechanism, a support frame and a material cylinder 19;

[0024] The frame includes a base 1, guide columns 2, top frame 3 and pressure frame 4. The top frame 3 is set at one end of the upper surface of the base 1 through several guide columns 2. The top frame 3 is equipped with a first hydraulic cylinder 5. The piston rod of the first hydraulic cylinder 5 is connected to the upper surface of the pressure frame 4. The lower surface of the pressure frame 4 is equipped with an upper mold 6. The base 1 is equipped with support plates 7 on both sides. The lower surface of the support plates 7 is equipped with reinforcing plates 22 to ensure the structural strength of the support plates 7. The lower surface of the base 1 is equipped with several support feet 23 to achieve overall lifting and support.

[0025] The lifting platform 8 is located below the upper mold 6 and has a female mold 9. The female mold 9 has several mold cavities 16. The two ends of the lower surface of the lifting platform 8 are connected to the piston rods of two second hydraulic cylinders 10. The second hydraulic cylinders 10 are embedded in the base 1. The upper surface of the lifting platform 8 and the two sides located at one end of the female mold 9 are symmetrically provided with limiting bosses 11. The lifting platform 8 and the pressure frame 4 are guided and cooperated with the guide column 2 through several guide sleeves to ensure the stability of the lifting platform 8 and the pressure frame 4 when lifting.

[0026] The feeding mechanism includes a cylinder 12 and a material box 13. The cylinder 12 is located on the upper surface of the lifting platform 8. The piston rod of the cylinder 12 is connected to the material box 13. The material box 13 is movably located on the upper surface of the lifting platform 8. The two sides of the material box 13 are slidably engaged with the limiting bosses 11. The inner side of the limiting bosses 11 is provided with guide grooves. The two sides of the material box 13 are provided with guide protrusions 20. The guide protrusions 20 are guided and engaged with the guide grooves. The material box 13 uses guide protrusions 20 to engage with the guide grooves of the limiting bosses 11, thereby ensuring the stability of the material box 13 and ensuring that the bottom of the material box 13 is in close contact with the upper surface of the base 1.

[0027] The lower mold 14 is set on the upper surface of the support platform 15, the support platform 15 is set on the upper surface of the base 1, and the lower mold 14 and the upper mold 6 correspond one-to-one with the mold cavity 16 and cooperate with each other.

[0028] The support frame includes support columns 17 and crossbeams 18. There are multiple support columns 17, which are connected to both ends of the crossbeams 18 respectively. The bottom of the support columns 17 is connected to the corresponding support plate 7. The bottom of the material cylinder 19 is vertically connected to the crossbeams 18. A valve 21 is provided at the bottom of the material cylinder 19 to discharge the metal powder material inside the material cylinder 19.

[0029] Working Method and Operating Principle: Metal powder is poured into the material cylinder 19. The lower mold 14 is located below the cavity 16 of the female mold 9. The piston rod of the first hydraulic cylinder 5 drives the pressure frame 4 to rise along the guide column 2. The valve 21 at the bottom of the material cylinder 19 opens, and the metal powder is added to the material box 13. The cylinder 12 drives the material box 13 forward until it reaches the female mold 9, where the metal powder is fed into the cavity 16 of the female mold 9. The material box 13 retracts, and the first hydraulic cylinder 5 drives the pressure frame 4 to descend, pressing the upper mold 6 into the cavity 16, where the metal powder is formed. The piston rod of the second hydraulic cylinder 10 retracts, and the lifting platform 8 descends. The formed material moves to the surface of the lifting platform 8 through the limit of the lower mold 14. The cylinder 12 drives the material box 13 forward, pushing the formed material away from the cavity 16, completing the one-time forming of the metal powder. This utility model has a reasonable structure. The cylinder 12 and the material box 13 are both set on the lifting platform 8. The lifting platform 8 is raised and lowered by four second hydraulic cylinders 10 connected to the base 1, which ensures the stability of the lifting platform 8 and thus the stability of the cylinder 12. The two sides of the base are supported by support columns 17 through the support plate 7. The top of the support column 17 is provided with a material cylinder 19 through the crossbeam 18. There is no need to install an external bracket for installing the material cylinder 19. The overall structure is more compact.
