Description

Technical Field

[0001] The utility model relates to the field of powder forming machines, in particular to a powder forming machine with a central mold that is easy to replace. Background Art

[0002] Powder forming machines are suitable for related industries such as inductor cores, powder metallurgy, precision ceramics, cemented carbide, magnetic materials, etc. that require powder pressing and forming, especially for pressing and forming products with complex shapes. Generally speaking, powder forming machines mainly include a middle die, an upper die and a lower die. By driving the middle die, the upper die and the lower die together, the powder is pressed and formed into a solid workpiece.

[0003] Since the middle mold is located between the upper and lower molds, there are many parts involved, and it is difficult to replace the mold core. At present, generally speaking, the middle mold mainly consists of a middle mold core and a middle mold base. The middle mold core is installed at the through hole in the middle of the middle mold base. As the middle mold base platform realizes functions such as powder feeding and material pushing, the upper surface of the middle mold base is prone to wear. Therefore, slideways are set around the middle mold core to provide movement for the powder box and the pusher head. It can be understood that the middle mold core will change with the change of production goals.

[0004] It can be seen that each time the middle mold core is changed, the horizontal condition between the slideway and the middle mold core needs to be readjusted, which will cause trouble and inconvenience. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to better illustrate the purpose, technical solution and advantages of the utility model, the specific implementation of the utility model is further described in detail below in conjunction with the drawings and embodiments. The following embodiments are used to illustrate the utility model, but are not intended to limit the scope of the utility model.

[0029] like Figures 1 to 7 As shown, a powder forming machine with an easily replaceable middle mold according to an embodiment of the utility model is shown from the whole to the part. The powder forming machine includes a forming main machine 100, a powder feeding mechanism 200, a material pushing mechanism 300, a control and power distribution cabinet 400 and an air source cabinet 500. The powder feeding mechanism 200 is located on the left and right sides of the forming main machine 100, and the material pushing mechanism 300 is located on the rear side of the forming main machine 100. The control and power distribution cabinet 400 is used to control the operation of the powder forming machine and to supply power to various parts. The air source cabinet 500 is used to provide air sources of various pressures.

[0030] In detail, the molding main machine 100 is composed of a machine base 10, a guide support column assembly 20, an upper mold assembly 30, a middle mold assembly 40 and a lower mold assembly 50. The guide support column assembly 20 is provided with four columns on the machine base 10. The upper mold assembly 30 includes an upper mold core 31, an upper mold base 32 and an upper mold drive 33. The upper mold drive 33 is composed of a motor and a transmission mechanism, is arranged at the upper part of the machine base 10, and drives the upper mold base 32 to move along the guide support column assembly 20. The upper mold core 31 is located in the mold clamping axis and is arranged downward on the lower side of the upper mold base 32. The middle mold assembly 40 includes a middle mold core 41, a middle mold base 42 and a middle mold drive 43. The middle mold drive 43 is also composed of a motor and a transmission mechanism, is arranged at the lower part of the machine base 10, and drives the middle mold base 42 to move along the guide support column assembly 20. The upper mold core 31 is located in the through hole of the middle mold base 42 in the mold clamping axis. The lower mold assembly 50 includes a lower mold core and a lower mold base. The lower mold base is fixed to the machine base 10, and the lower mold core is arranged upward on the upper side of the lower mold base. When the upper mold core 31, the middle mold core 41 and the lower mold core are molded, the powder inside can be pressed and molded. After molding, the movement of the upper mold core 31 and the middle mold core 41 can eject the molded workpiece.

[0031] The powder feeding mechanism 200 includes a powder box 71, which is a through structure from top to bottom. The horizontal cross section of the powder box 71 is a rectangular shape. The two opposite sides of the powder box 71 are respectively provided with hinge shafts. It can be understood that as the powder box 71 abuts against the upper surface of the middle mold base 42 and moves toward the center of the mold, the powder can be pushed into the mold cavity, and after filling, it will move away from the mold cavity, and the mold will be closed. In the left and right powder feeding mechanisms 200, the powder box 71 can be filled with different powders, so that the workpiece can be extruded by composite powder.

[0032] Among them, the pushing mechanism 300 includes a pushing head 72. It can be understood that after the workpiece is formed, it will be pushed onto the middle mold base 42, and the pushing head 72 can push the molded workpiece to the front side, leave the equipment along the slope and be collected. It can be understood that in the powder molding process, residual powder is inevitable on the upper surface of the middle mold base 42, and different powder mixtures will no longer be suitable for the molding of the workpiece and need to be cleaned. Therefore, the interior of the pushing head 72 is a hollow cavity, a sliding plane is provided at the bottom of the pushing head 72, a slit structure 721 is provided at the front side of the bottom of the pushing head 72, and an interface 722 for connecting to a vacuum source is provided on the rear side of the pushing head 72. When the interface 722 is connected to the vacuum source, the slit structure 721 of the pushing head 72 will generate a vacuum suction force, and the waste powder will be sucked out.

[0033] Therefore, it is worth noting that the material pushing mechanism 300 and the two powder feeding mechanisms 200 of this embodiment require a larger horizontal sliding area.

[0034] To this end, the middle mold assembly 40 includes a middle mold base 42 and a middle mold core 41. The middle mold core 41 is detachably installed in the central through hole of the middle mold base 42. The middle mold assembly 40 also includes an inlay panel 45.

[0035] Specifically, in this embodiment, the middle mold assembly 40 further includes an inlay bottom plate 44, which is installed on the middle mold base 42, and the inlay bottom plate 44 is provided with a through hole, and the through hole of the inlay bottom plate 44 allows the middle mold core 41 to pass through, and the middle panel 451 and the side panel 452 are installed on the inlay bottom plate 44 in a manner that the upper side faces are coplanar, and the installation datum between the inlay bottom plate 44 and the middle mold base 42 and the installation datum between the middle mold core 41 and the middle mold base 42 are matched, so that the middle mold core 41, the middle panel 451 and the side panel 452 are coplanar after installation. Therefore, when the middle panel 451 is installed back on the inlay bottom plate 44 again, the level between the middle panel 451 and the middle mold core 41, and the level between the middle panel 451 and the side panel 452 are automatically maintained.

[0036] Specifically, in this embodiment, the middle panel 451 and the side panel 452 are both rectangular in shape, the inlay bottom plate 44 is also rectangular in shape, and strip-shaped protrusions are provided on the front and rear sides of the inlay bottom plate 44. The widths of the middle panel 451 and the side panel 452 are matched to be fixed on the inlay bottom plate 44 and located between the two strip-shaped protrusions. After the middle panel 451 and the side panel 452 are installed on the inlay bottom plate 44, they are coplanar with the strip-shaped protrusions. Therefore, the inlay bottom plate 44 can also have a coplanar and smooth transition between the middle panel 451 and the side panel 452.

[0037] Specifically, in this embodiment, the upper edge of the central core mold is circular, and the through hole of the central panel is also circular.
