[0033] Example 1:

[0034] like Figures 1-4 As shown, this utility model provides a forming mold 1 for pressing alloy circular blades, including: a first mold plate 10, a second mold plate 20, a third mold plate 30, and a first positioning plate 40. The first mold plate 10 is provided with a through hole 11 in the height direction. The second mold plate 20 is disposed in the through hole 11, and the outer peripheral wall of the second mold plate 20 abuts against the inner peripheral wall of the through hole 11. A forming space 14 opening towards the top is defined between the top of the second mold plate 20 and the through hole 11. The forming space 14 is suitable for placing alloy powder. The third mold plate 30 is disposed on the top of the through hole 11. The projection of the third mold plate 30 in the height direction overlaps with the through hole 11. The first positioning plate 40 is movably disposed on the second mold plate 20. The first positioning plate 40 moves to position the third mold plate 30. The center of the third mold plate 30 after positioning overlaps with the projection of the center of the through hole 11 in the height direction.

[0035] In some embodiments, a first mold plate 10 is a basic component. The interior of the first mold plate 10 is provided with a through hole 11, which is provided through in the height direction, that is, the through hole 11 completely penetrates the first mold plate 10 from top to bottom. A second mold plate 20 is disposed in the through hole 11 of the first mold plate 10, and the outer peripheral wall of the second mold plate 20 is in close contact (stop) with the inner peripheral wall of the through hole 11 to ensure the stability and sealing between the second mold plate 20 and the through hole 11. An open upward forming space 14 is formed between the top of the second mold plate 20 and the through hole 11. The forming space 14 is specifically used to place the alloy powder to be pressed. A third mold plate 30 is located on top of the through hole 11, and the projection of the third mold plate 30 overlaps with the through hole 11. A first positioning plate 40 is movably mounted on the second mold plate 20. By moving the first positioning plate 40, the position of the third mold plate 30 can be adjusted and fixed so that the center of the third mold plate 30 is aligned with the projection of the center of the through hole 11 in the height direction.

[0036] It is understood that the molding die 1 of this application is suitable for use with a cold press. The cold press includes a worktable and a moving table. During production, the second mold plate 20 is first placed in the through hole 11. At this time, the top of the second mold plate 20 and the inner peripheral wall of the through hole 11 define a molding space 14. Then, alloy powder is poured into the molding space 14. At this time, the alloy powder in the molding space 14 is leveled using a scraper or the like (the top surface of the leveled alloy powder is flush with the top surface of the first mold plate 10). Then, the third mold plate 30 is placed on top of the first mold plate 10, and then pushed... The first positioning plate 40 is moved to drive the third mold plate 30 until the projection of the center of the third mold plate 30 onto the center of the through hole 11 in the height direction overlaps. Finally, the cold press is started, causing the moving table to move towards the worktable in the height direction. The moving table moves until it abuts against the third mold plate 30, and drives the third mold plate 30 until at least a portion of it is located within the through hole 11. Thus, the first mold plate 10, the second mold plate 20, and the third mold plate 30 press the alloy powder into a circular blade using pressure. The circular blade formed from the alloy powder undergoes subsequent processing to form the final product.

[0037] It is worth mentioning that when using a scraper to level the alloy powder, the operator can move the first positioning plate 40 to the outer periphery of the first mold plate 10 to avoid the first positioning plate 40 from hindering the scraping movement, thereby improving the leveling efficiency of the alloy powder.

[0038] According to the alloy circular blade pressing forming mold 1 of this utility model, the first positioning plate 40 moves to drive the third mold plate 30 to move, and the center of the third mold plate 30 overlaps with the center of the through hole 11. That is, this application only needs to move the first positioning plate 40 to realize the alignment of the third mold plate 30 and the through hole 11. The operation is simple and easy to implement, avoiding the workers from spending a lot of time aligning the third mold plate 30 and the through hole 11, thus improving the production efficiency of alloy circular blades.

[0039] Example 2:

[0040] Based on Embodiment 1, the first positioning plate 40 is provided with an arc-shaped groove facing the through hole 11, and the inner peripheral wall of the arc-shaped groove is adapted to abut against the outer peripheral wall of the third mold plate 30.

[0041] It is understandable that the first positioning plate 40 has a groove of a specific shape. The groove has an arc-shaped outline, which is intended to match the circular shape of the third mold plate 30. Thus, the inner surface of the arc-shaped groove can closely fit the outer edge of the third mold plate 30, so as to ensure that the third mold plate 30 can be subjected to uniform force when the first positioning plate 40 pushes the third mold plate 30, thereby enabling the third mold plate 30 to move stably along the preset route and ensuring the positioning effect of the third mold plate 30.

[0042] Of course, the inner peripheral wall of the arc groove tightly wraps around the outer peripheral wall of the third mold plate 30, which can also ensure that the center of the third mold plate 30 and the center of the through hole 11 remain aligned throughout the pressing process.

[0043] According to some embodiments of the present invention, the first positioning plate 40 is constructed as two, and the two first positioning plates 40 are respectively disposed at both ends of the second mold plate 20 in the length direction.

[0044] In some embodiments, the two first positioning plates 40 can move inward from both ends of the second mold plate 20 simultaneously to contact and fix the third mold plate 30. The two first positioning plates 40 provide a more uniform pressure distribution and help ensure that the center of the third mold plate 30 is aligned with the center of the through hole 11 in the height direction, making the positioning of the third mold plate 30 more accurate, ensuring the smooth pressing of the circular blade, and improving the production efficiency of the circular blade.

[0045] According to some embodiments of the present invention, the top of the second mold plate 20 is provided with a first slide groove 12 extending in the length direction, and the bottom of the first positioning plate 40 is provided with a first slider, which is movably disposed in the first slide groove 12.

[0046] It is understandable that the inner peripheral wall of the first slide groove 12 can restrict the outer peripheral wall of the first slider, so that the first slider can move stably along the extension direction of the first slide groove 12, thereby allowing the first positioning plate 40 to move stably along the preset path, and thus allowing the first positioning plate 40 to drive the third mold plate 30 to move stably, ensuring the positioning effect of the third mold plate 30.

[0047] Example 3:

[0048] Based on Embodiment 2, in this embodiment, the bottom of the first mold plate 10 is provided with a plurality of stop blocks 13, which are spaced apart on the outer periphery of the through hole 11; wherein when the second mold plate 20 is housed in the through hole 11, the bottom of the second mold plate 20 and the bottom of the stop blocks 13 are on the same plane.

[0049] In some embodiments, a plurality of stop blocks 13 are respectively disposed at the bottom of the first mold plate 10, and the plurality of stop blocks 13 are disposed around the outer periphery of the through hole 11, while the plurality of stop blocks 13 are spaced apart from each other.

[0050] Preferably, the height of the first mold plate 10 is equal to the height of the second mold plate 20. Thus, when the bottom of the second mold plate 20 and the bottom of the stop block 13 are on the same plane, the height of the stop block 13 is equal to the height of the forming space 14. Therefore, the above arrangement can ensure the volume of alloy powder in the forming space 14 each time, thereby ensuring the forming quality of each batch of alloy circular blades and ensuring the consistency of production.

[0051] According to some embodiments of the present invention, the molding die 1 further includes a base plate 50, which is disposed below the first mold plate 10, and the top of the base plate 50 is adapted to abut against the bottom of the stop block 13.

[0052] In some embodiments, the base plate 50 is configured as the base of the forming mold 1. The base plate 50 is adapted to be placed on the surface of the workbench. The top of the base plate 50 is provided to stop the bottom of the stop block 13 and the bottom of the second mold plate 20. Thus, the arrangement of the base plate 50 can ensure that the bottom of the stop block 13 and the bottom of the second mold plate 20 are on the same plane, thereby ensuring the forming effect of the alloy circular blade and thus ensuring the production quality of the alloy circular blade.

[0053] Example 4:

[0054] Based on Embodiment 3, the molding mold 1 further includes a demolding ring 60, which is disposed between the base plate and the second mold plate 20. The projection of the demolding ring 60 in the height direction is located within the second mold plate 20.

[0055] In some embodiments, after the alloy powder is pressed and formed in the forming space 14, the operator can place the demolding ring 60 between the base plate 50 and the second mold plate 20. Then, multiple demolding modules (with a height greater than the third mold plate 30) are placed on top of the second mold plate 20. The operator then starts the cold press, which moves the moving platform toward the worktable until it abuts against the demolding modules. This movement indirectly drives the first mold plate 10 to move relative to the second mold plate 20 and the third mold plate 30 in the height direction. When the first mold plate 10 moves until its horizontal projection is spaced apart from the second mold plate 20, the demolding process is complete. The operator can then remove the pressed alloy circular blade by moving the second mold plate 20 and / or the third mold plate 30 in the height direction.

[0056] According to some embodiments of the present invention, a movable second positioning plate 70 is provided on the base plate 50. The second positioning plate 70 can be moved to selectively position the demolding ring 60. The center of the demolding ring 60 after positioning overlaps with the center of the second mold plate 20 in the height direction.

[0057] Understandably, the presence of the second positioning plate 70 significantly improves the positioning accuracy of the demolding ring 60, reducing the risk of product defects or demolding failure due to positional deviations. Moreover, by ensuring that the demolding ring 60 is aligned with the center of the second mold plate 20, it can provide more stable demolding support, avoiding product deformation or damage caused by asymmetrical pressure. Of course, the movable second positioning plate 70 design simplifies the positioning process of the demolding ring 60, making the operation more intuitive and convenient, reducing the time and difficulty of manual operation, and improving the production efficiency of alloy circular inserts.

[0058] According to some embodiments of the present invention, the second positioning plate 70 includes: a first split part 71 and a second split part 72. The first split part 71 is movably connected to the base plate 50. The first split part 71 is provided with a first stop surface facing the demolding ring 60. The first stop surface is adapted to stop against the outer peripheral wall of the demolding ring 60. The top of the first split part 71 is provided with a first region and a second region. The first region is arranged around the outer periphery of the second region. The second region is adapted to stop against the bottom of the stop block 13. The second split part 72 is disposed in the first region. The second split part 72 is provided with a second stop surface facing the stop block 13. The second stop surface is adapted to stop against the outer peripheral wall of the stop block 13.

[0059] In some embodiments, the first stop surface of the first split portion 71 ensures the precise positioning of the demolding ring 60, so that the center of the demolding ring 60 is in a preset position. The contact between the second stop surface of the second split portion 72 and the outer peripheral wall of the stop block 13 allows the stop block 13 to also be in a preset position, thereby placing the first mold plate 10, the second mold plate 20 and the third mold plate 30 in preset positions respectively. When both the demolding ring 60 and the second mold plate 20 are in preset positions, the projections of the center of the demolding ring 60 and the center of the second mold plate 20 in the height direction overlap.

[0060] Therefore, the above settings can further ensure that the center of the demolding ring 60 and the center of the second mold plate 20 overlap in the height direction, thereby ensuring demolding efficiency and demolding quality.

[0061] Of course, the contact between the second region and the bottom of the stop block 13 provides additional vertical support for the second mold plate 20, enhancing the placement stability of the first mold plate 10, the second mold plate 20, and the third mold plate 30.

[0062] In some embodiments, a second slide groove 51 is provided on the top of the base plate 50, the second slide groove 51 extends in the length direction, and a second slider is provided on the bottom of the second positioning plate 70, the second slider being movably disposed within the second slide groove 51.

[0063] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
