[0002] like Figure 1 to Figure 3 As shown, the structure of the inner hook (also called product) is usually formed by bending the inner hook by a bending mold, for example, by step-by-step bending, first bending one side and then bending the other side, or by combining multiple bending, first bending the same side for the first time and then bending the same side for the second time; the bending mold in the prior art has a bending punch and a bending die, and the product is located between the bending punch and the bending die and is bent. The inner hook after bending has a first inner hook edge, a second inner hook edge and a third inner hook edge, which are connected in sequence and form an approximately frame-shaped structure. After bending is completed; first, along the first horizontal direction, a worker needs to manually pull out the bending die to separate the bending die from the second inner hook edge; second, along the second horizontal direction, the width of the bending die cannot be adjusted. Therefore, the bending die cannot be separated from the first inner hook edge and the third inner hook edge along the second horizontal direction; wherein the first horizontal direction and the second horizontal direction are perpendicular to each other and are parallel to the upper surface of the inner hook; that is, in the prior art, after bending, the bending die located at the bottom of the inner hook is difficult to automatically separate from the inner hook.

The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the utility model, and cannot be understood as limitations on the utility model.
[0049] Example 1
[0050] like Figures 4 to 6As shown, this embodiment is a preferred embodiment of the utility model, and this embodiment proposes an inner hook bending mold, which includes an upper mold base 1 and a lower mold base 2, and the upper mold base 1 is movable along the vertical direction; it also includes an upper clamping component 3 and a lower clamping component 4, the upper clamping component 3 is connected to the upper mold base 1, and the lower clamping component 4 is connected to the lower mold base 2, and along the vertical direction, the upper clamping component 3 and the lower clamping component 4 are close to each other or separated from each other; it also includes a sliding plate 14, and along the first horizontal direction, the sliding plate 14 is movably arranged on the lower mold base 2; it also includes a first elastic mechanism 6, and along the first horizontal direction, one end of the first elastic mechanism 6 is connected to the lower mold base 2, and the other end abuts against one end of the sliding plate 14 side; it also includes a width adjustment mechanism 5, which is arranged on the sliding plate 14. Along the vertical direction, the position of the upper surface of the width adjustment mechanism 5 is lower than the preset distance of the upper surface of the lower clamping component 4; the width adjustment mechanism 5 at least includes a first lower slider 502 and a second lower slider 503, and the first lower slider 502 and the second lower slider 503 are distributed along the second horizontal direction; it also includes a first lifting mechanism 7, the first lifting mechanism 7 is connected to the lower mold base 2, and the first lower slider 502 and the second lower slider 503 can be driven by the first lifting mechanism 7 to approach each other along the second horizontal direction; the vertical direction, the first horizontal direction, and the second horizontal direction are perpendicular to each other.
[0051] The structures of the upper die base 1 and the lower die base 2 are prior art and will not be described in detail here. The inner hook bending die is usually installed on a stamping machine, and the upper die base 1 moves closer to or away from the lower die base 2 under the drive of the stamping machine.
[0052] The upper clamping part 3 at least includes a stripper plate assembly, the structure of which is of prior art and will not be described in detail here; the lower clamping part 4 is a rectangular block. Driven by the upper die base 1, the upper clamping part 3 can approach or separate from the lower clamping part 4. When the upper clamping part 3 and the lower clamping part 4 approach each other in the vertical direction, the product is clamped, and when the upper clamping part 3 and the lower clamping part 4 separate in the vertical direction, the product is loosened.
[0053] The sliding plate 14 is preferably a plate-shaped structure, and both the upper surface and the lower surface are flat. The first elastic mechanism 6 is an elastic member, preferably a nitrogen spring.
[0054] The width adjustment mechanism 5, in the closed mold state, along the vertical direction, the position of the upper surface of the width adjustment mechanism 5 is lower than the position of the upper surface of the lower clamping part 4 by a preset distance; the preset distance can be configured according to the specific situation, and the preset distance should not be too large. For example, in the present embodiment, the preset distance is within 0.5mm; the purpose of this setting is: on the one hand, if the position of the upper surface of the width adjustment mechanism 5 is higher than the position of the upper surface of the lower clamping part 4, the upper clamping part 3 and the lower clamping part 4 cannot clamp the product in the vertical direction at any time. In order to avoid this situation, this design is provided; on the other hand, during the unloading process, the width adjustment mechanism 5 needs to be separated from the product along the first horizontal direction. In the present embodiment, the upper clamping part 3 and the lower clamping part 4 clamp the product to avoid the width adjustment mechanism 5 driving the product to move along the first horizontal direction during the separation of the width adjustment mechanism 5 from the product.
[0055] like Figure 6 to Figure 8 As shown, in this embodiment, in addition to the first lower slider 502 and the second lower slider 503, the width adjustment mechanism 5 should also have the following characteristics: the width adjustment mechanism 5 also includes a lower die 501, and along the second horizontal direction, the first lower slider 502 and the second lower slider 503 are respectively distributed on both sides of the lower die 501; the first lower slider 502 and the lower die 501 form a first sliding pair along the first preset direction, and the second lower slider 503 and the lower die 501 form a second sliding pair along the second preset direction; wherein, the first preset direction and the vertical direction form a first preset angle, and the second preset direction and the vertical direction form a second preset angle; in the vertical direction from the lower die base 2 to the upper die base 1, the first preset direction and the second preset direction are convergent. Preferably, the first preset angle and the second preset angle are acute angles respectively; the first lower slider 502 and the second lower slider 503 have a first state and a second state, when in the first state, along the second horizontal direction, the distance between the first lower slider 502 and the second lower slider 503 is a first distance, and when in the second state, along the second horizontal direction, the distance between the first lower slider 502 and the second lower slider 503 is a second distance, and the first distance is greater than the second distance; in the process of transitioning from the first state to the second state, the first lower slider 502 and the second lower slider 503 approach each other at the same time and speed.
[0056] Furthermore, the inner hook bending mold of the present embodiment also includes an upper insert knife 11, which is connected to the upper mold base 1; and also includes a lower insert knife 12, which is connected to the sliding plate 14; the upper insert knife 11 is provided with a first inclined surface, and the lower insert knife 12 is provided with a second inclined surface, the first inclined surface is arranged toward the first elastic mechanism 6, and the second inclined surface is arranged away from the first elastic mechanism 6; the first inclined surface and the second inclined surface are both at acute angles to the vertical direction; during the movement of the upper mold base 1 along the vertical direction, the first inclined surface and the second inclined surface slide into contact with each other or separate from each other; along the first horizontal direction, the upper insert knife 11 and the lower insert knife 12 are located between the first elastic mechanism 6 and the lower clamping component 4.
[0057] As mentioned above, the width adjustment mechanism 5 is movable along the first horizontal direction on the lower die base 2; specifically, it has two power sources:
[0058] The first power source is generated when the upper die base approaches the lower die base, specifically: during the vertical downward movement of the upper die base 1, the first inclined surface and the second inclined surface slide in contact with each other, and the upper insert knife 11 pushes the lower insert knife 12 together with the sliding plate 14 and the various components arranged on the sliding plate 14 to move away from the lower clamping component 4 along the first horizontal direction, that is, drives the width adjustment mechanism 5 to move away from the lower clamping component 4 along the first horizontal direction.
[0059] The second power source is generated when the upper die seat moves away from the lower die seat, specifically: along the first horizontal direction, one end of the first elastic mechanism 6 is connected to the lower die seat 2, and the other end abuts against one side of the sliding plate 14. When in use, in the process of the upper die seat approaching the lower die seat and the upper inserting knife 11 pushing the lower inserting knife 12 to move away from the lower clamping part 4 along the first horizontal direction, the first elastic mechanism 6 is compressed; in the process of the upper die seat moving away from the lower die seat, the first elastic mechanism 6 is activated by its own elastic force and pops open, thereby driving the sliding plate 14 and the various components arranged on the sliding plate 14 to move toward the lower clamping part 4 along the first horizontal direction, that is, driving the width adjustment mechanism 5 to move toward the lower clamping part 4 along the first horizontal direction. This process is also the process of the width adjustment mechanism 5 separating from the inner hook along the first horizontal direction after bending.
[0060] As mentioned in the foregoing content, the width adjustment mechanism 5 is adjustable in width along the second horizontal direction under the drive of the first lifting mechanism 7; see below for details:
[0061] like Figure 5 , Fig. 9As shown, the first lifting mechanism 7 includes a first push rod 701, which is connected to the upper mold base 1; the first lifting mechanism 7 also includes a floating plate 702 and a base 703, along the vertical direction, the floating plate 702 is located between the base 703 and the lower mold base 2, and a second elastic mechanism 704 is arranged between the floating plate 702 and the base 703; the first lifting mechanism 7 also includes a second push rod 705, one end of the second push rod 705 abuts the floating plate 702, and the other end can contact or separate from the first push rod 701 along the vertical direction; the first lifting mechanism 7 also includes a first thin rod 706, one end of the first thin rod 706 abuts the floating plate 702, and the other end extends to the bottom of the first lower sliding block 502 along the vertical direction; the first lifting mechanism 7 also includes a second thin rod 707, one end of the second thin rod 707 abuts the floating plate 702, and the other end extends to the bottom of the second lower sliding block 503 along the vertical direction. Preferably, the second elastic mechanism 704 is a nitrogen spring; preferably, the inner hook bending mold also includes a padding plate 15, which is arranged between the lower mold base 2 and the sliding plate 14 along the vertical direction, and the sliding plate 14 is movably arranged on the padding plate 15; it also includes a first channel, which passes through the lower mold base 2, the padding plate 15, and the sliding plate 14 along the vertical direction; and the number of the first channels is at least two, and the two first channels are respectively movably penetrated by the first thin rod 706 or the second thin rod 707.
[0062] When the upper die seat moves toward the lower die seat and bends the product, the first push rod 701 pushes the second push rod 705 downward, and the second push rod 705 pushes the floating plate 702 to squeeze the second elastic mechanism 704. At the same time, the first thin rod 706 and the second thin rod 707 move downward under the drive of the floating plate 702. When the upper die seat moves away from the lower die seat, the first push rod 701 separates from the second push rod 705, and the second elastic mechanism 704 pushes the floating plate 702 upward under the action of its own elastic force, and the floating plate 702 drives the first thin rod 706 and the second thin rod 707. Moving upward, the first thin rod 706 pushes the first lower slider 502 to move obliquely upward along the first preset direction on one side of the lower die 501, and the second thin rod 707 pushes the second lower slider 503 to move obliquely upward along the second preset direction on the other side of the lower die 501; during the oblique upward movement of the first lower slider 502 and the second lower slider 503, the first lower slider 502 and the second lower slider 503 gradually approach each other along the second horizontal direction, thereby constituting the "adjustment mechanism 5 can be adjusted in width along the second horizontal direction under the drive of the first lifting mechanism 7" mentioned in the above content.
[0063] Furthermore, this embodiment also includes the following technical solutions:
[0064] The inner hook bending mold also includes a first support block 16 and a second support block 17. Along the first horizontal direction, the first support block 16 and the second support block 17 are respectively connected to the lower mold base 2; along the first horizontal direction, the pad plate 15 is immovably restricted between the first support block 16 and the second support block 17.
[0065] The first support block 16 is provided with a first limiting portion, and the second support block 17 is provided with a second limiting portion; along the first horizontal direction, the movable range of the sliding plate 14 is limited by the first limiting portion and the second limiting portion.
[0066] The inner hook bending mold also includes an upper punch 10, which is connected to the upper mold base 1; along the first horizontal direction, the minimum spacing between the upper punch 10 and the width adjustment mechanism 5 is configured as a preset spacing; the preset spacing is configured according to the thickness of the inner hook, and there is no restriction here; along the vertical direction, the upper punch 10 and the width adjustment mechanism 5 are close to or away from each other.
[0067] As for the bending process of the product, this embodiment realizes it together through the upper punch 10 and the width adjustment mechanism 5; when bending, the part of the product to be bent is located between the upper punch 10 and the width adjustment mechanism 5, the upper die seat drives the upper punch 10 to move downward, and the width adjustment mechanism 5 presses upward against the part of the product to be bent, and the upper punch 10 and the width adjustment mechanism 5 exert opposite forces on the part of the product to be bent, thereby bending the product.
[0068] like Figure 7-Figure 8 As shown, further, the width adjustment mechanism 5 is provided with a plurality of making way steps 13 for making way for the inner hook bending part of the inner hook member.
[0069] The connection relationship not explained in detail in the above content can adopt one of the existing technologies, such as the parts are fixed by blocks, or fixed by screws or bolts.
[0070] Furthermore, this embodiment also includes the following technical solutions:
[0071] A guide block 8 is also provided on the raising plate 15, and a guide groove 9 is provided on the guide block 8. The guide groove 9 extends along the first horizontal direction, and the sliding plate 14 and the guide groove 9 form a sliding pair along the first horizontal direction. When the sliding plate 14 moves along the first horizontal direction, the guide groove 9 guides the sliding plate 14 along the first horizontal direction.
[0072] When the inner hook bending mold of this embodiment is used, the process from mold opening to mold closing is as follows:
[0073] The product is placed on the width adjustment mechanism 5; the upper die base 1 moves toward the lower die base 2, and the upper insert knife 11 and the lower insert knife 12 are in sliding contact through the first inclined surface and the second inclined surface. The upper insert knife 11 pushes the lower insert knife 12 together with the sliding plate 14 and the various components arranged on the sliding plate 14 to move away from the lower clamping component 4 along the first horizontal direction, that is, the width adjustment mechanism 5 is driven to move away from the lower clamping component 4 along the first horizontal direction until it is between the upper punch 10 and the width adjustment mechanism 5 along the first horizontal direction; at the same time, the first elastic mechanism 6 is compressed until the first inclined surface and the second inclined surface are separated from each other, and a vertical side surface of the upper insert knife 11 contacts a vertical side surface of the lower insert knife, at which time the lower insert knife 12 and the width adjustment mechanism 5 stop moving;
[0074] The upper die base 1 continues to move toward the lower die base 2, and the upper clamping component 3 and the lower clamping component 4 clamp the product in the vertical direction;
[0075] The first push rod 701 contacts the second push rod 705 and pushes the second push rod 705 to move downward. The second push rod 705 drives the floating plate 702 and compresses the second elastic mechanism 704 downward. The first thin rod 706 and the second thin rod 707 are separated from the first lower slider 502 and the second lower slider 503 respectively.
[0076] The upper die base 1 continues to move toward the lower die base 2, and the upper punch 10 and the width adjustment mechanism 5 act together on the product in the vertical direction to bend the product into a hook shape, that is, to bend the product into a first inner hook edge, a second inner hook edge, and a third inner hook edge.
[0077] The process from mold closing to mold opening:
[0078] The upper die base 1 moves vertically in a direction away from the lower die base 2, the upper inserting knife 11 and the lower inserting knife 12 slide and contact through the first inclined surface and the second inclined surface, the first elastic mechanism 6 is ejected by its own elastic force, and the first elastic mechanism 6 pushes the sliding plate and various components arranged on the sliding plate 14 to move toward the lower clamping component 4 along the first horizontal direction, that is, pushes the width adjustment mechanism 5 to move toward the lower clamping component 4; in this process, the upper clamping component 3 and the lower clamping component 4 always clamp the product along the vertical direction, so that the width adjustment mechanism 5 and the product move relatively along the first horizontal direction, and the width adjustment mechanism 5 is separated and exited from the second inner hook edge of the product along the first horizontal direction;
[0079] The upper die base 1 continues to move vertically in the direction away from the lower die base 2, the first push rod 701 separates from the second push rod 705, the second elastic mechanism 704 pops open under its own elastic force, driving the floating plate 702 to move upward, and the floating plate 702 drives the first thin rod 706 and the second thin rod 707 to move upward, until the first thin rod 706 pushes the first lower slider 502 to move obliquely upward along the first preset direction, and the second thin rod 707 pushes the second lower slider 503 to move obliquely upward along the second preset direction, along the second horizontal direction, the first lower slider 502 and the second lower slider 503 approach each other, and then along the second horizontal direction, the width adjustment mechanism 5 separates from the first inner hook edge and the third inner hook edge of the product and exits;
[0080] Finally, the worker removes the bent product from the inner hook bending mold, completing the entire bending process.
[0081] As can be seen from the background technology, the technical problem existing in the prior art is the lack of a bending die specially designed for the inner hook, which can automatically separate the bending die and the inner hook from each other after the inner hook is bent.
[0082] In this embodiment, the width adjustment mechanism 5 is equivalent to the bending die in the prior art; after the inner hook, which can also be called a product, is bent, the upper clamping part 3 and the lower clamping part 4 clamp the inner hook, and the width adjustment mechanism 5 is automatically driven by the first elastic mechanism 6 to slide along the first horizontal direction, so that the width adjustment mechanism 5 is separated from the second inner hook edge of the inner hook along the first horizontal direction, and, under the action of the first lifting mechanism 7, the first lower slider 502 and the second lower slider 503 of the width adjustment mechanism 5 automatically approach each other along the second horizontal direction, so that the width adjustment mechanism 5 is separated from the first inner hook edge and the third inner hook edge of the inner hook along the second horizontal direction; therefore, this embodiment realizes that after the inner hook is bent, the width adjustment mechanism 5 is automatically separated from the inner hook.
[0083] In summary, the present embodiment solves the technical problem existing in the technology: the lack of a bending die specially designed for the inner hook, which can automatically separate the bending die and the inner hook from each other after the inner hook is bent.
