[0042] Here, exemplary embodiments will be described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] In the present disclosure, it should be noted that the "first movement position" involved in the present disclosure does not refer to a fixed position of the locking body 2. It can be that the locking body 2 is in multiple different positions. As long as the position of the locking body 2 can be locked and cooperated with the first locking portion 41 of the movable member 4 to limit the movement of the movable member 4, it is included in the protection scope of the above-mentioned first movement position. Similarly, the "second movement position" involved in the present disclosure is not a fixed position of the locking body 2. It can be that the locking body 2 is in multiple different positions. As long as the position of the locking body 2 can be unlocked from the first locking portion 41 of the movable member 4 to release the movement restriction of the movable member 4, it can be included in the protection scope of the above-mentioned second movement position. In addition, the terms such as "first, second" are only used to distinguish one element from another element, and do not have sequentiality and importance.

[0044] Referring to Figures 1 to 4 As shown, the present disclosure provides a locking mechanism 100. The locking mechanism 100 includes a cable 1, a locking body 2, and a reset member 3. Both the cable 1 and the reset member 3 are connected to the locking body 2. The locking body 2 is configured to be movably disposed on a die frame (not shown) of a stamping die, and the locking body 2 has a first movement position and a second movement position. In the first movement position, the locking body 2 can be used to lock and cooperate with the first locking portion 41 of the movable member 4 of the stamping die. In the second movement position, the locking body 2 can release the locking cooperation with the first locking portion 41 of the movable member 4. One of the cable 1 and the reset member 3 can drive the locking body 2 to move from the first movement position to the second movement position, and the other can drive the locking body 2 to move from the second movement position to the first movement position.

[0045] In the above technical solution, when the locking body 2 is in the first movement position, the locking body 2 can be locked and cooperated with the first locking portion 41 of the movable member 4 of the stamping die. At this time, the movable member 4 cannot move, realizing the limitation of the movable member 4 of the stamping die. When the locking body 2 is in the second movement position, the locking body 2 can release the locking cooperation relationship with the first locking portion 41. At this time, the movable member 4 can move, thereby releasing the limitation of the movable member 4 of the stamping die.

[0046] In addition, since both the cable 1 and the reset member 3 are connected to the locking body 2, when an operator needs to lock and limit the movable member 4, the cable 1 can be pulled to drive the locking body 2 to move to the first movement position, so that the locking body 2 is in locking cooperation with the first locking portion 41 of the movable member 4. When it is necessary to release the limit on the movable member 4, the reset member 3 can be used to move the locking body 2 from the second movement position to the first movement position. Alternatively, when the operator needs to unlock the movable member 4, the cable 1 can be pulled to drive the locking body 2 to move to the second movement position. When it is necessary to lock and limit the movable member 4, the reset member 3 can be used to move the locking body 2 from the second movement position to the first movement position to lock the movable member 4. That is, by operating the locking body 2 through the cable 1 and the reset member 3, the locking, limiting and unlocking of the movable member 4 of the stamping die are realized. The mechanical structure can effectively avoid the problem of air pressure loss in the air circuit caused by using a pneumatic switching mechanism, and has stronger reliability.

[0047] For the movement mode of the above-mentioned locking body 2, it can be a moving mode, a rotating mode, or a combination of moving and rotating modes. The present disclosure does not limit this.

[0048] For example, in an optional embodiment (not illustrated in this example), the locking body 2 is movably arranged on the mold frame, and the locking body 2 can approach or move away from the movable member 4. The movable member 4 can be configured as a sliding block of the slider mechanism 200 of the stamping die. The first locking portion 41 on the movable member 4 can include a first stop protrusion (not illustrated) and a second stop protrusion (not illustrated) arranged at intervals along the moving direction of the movable member 4. When the locking body 2 is arranged close to the movable member 4, the locking body 2 is in the first movement position, and the locking body 2 is inserted between the first stop protrusion and the second stop protrusion, and the locking body 2 abuts against the first stop protrusion and the second stop protrusion to realize the locking and limiting of the movable member 4. When the locking body 2 is arranged away from the movable member 4, the locking body 2 is in the second movement position, and the locking body 2 disengages from between the first stop protrusion and the second stop protrusion to realize the unlocking of the movable member 4.

[0049] In other embodiments, refer to Figure 1 and Figure 2 As shown, the locking body 2 is rotatably arranged on the mold frame around the first axis. Among them, one of the cable 1 and the reset member 3 can drive the locking body 2 to rotate from the first movement position to the second movement position, and the other can drive the locking body 2 to rotate from the second movement position to the first movement position. That is, in this embodiment, the locking body 2 is arranged on the mold frame in a rotating manner, and the locking and unlocking of the movable member 4 can also be realized.

[0050] Optionally, refer toFigure 2 and Figure 3 As shown in Figure 3 , the locking body 2 includes a rotating shaft 21 and a driving arm 22. The rotating shaft 21 is rotatably arranged on the mold frame around a first axis, and the driving arm 22 is angularly connected to the rotating shaft 21; the cable 1 is connected to the driving arm 22, and the reset member 3 is arranged on the mold frame and connected to the driving arm 22; wherein, the rotating shaft 21 includes a second locking portion; when the locking body 2 is in a first movement position, the second locking portion can be used for locking cooperation with a first locking portion 41 of the movable member 4; when the locking body 2 is in a second movement position, the rotating shaft 21 can release the locking cooperation with the first locking portion 41 of the movable member 4.

[0051] In this embodiment, by angularly arranging the driving arm 22 on the rotating shaft 21, and both the cable 1 and the reset member 3 are connected to the driving arm 22, when the operator pulls the cable 1, due to the arrangement of the driving arm 22, the torque can be effectively transmitted to the rotating shaft 21, thereby driving the rotation of the rotating shaft 21. Similarly, due to the arrangement of the driving arm 22, the reset member 3 can also effectively transmit the torque to the rotating shaft 21 to drive its rotation. In addition, by arranging a second locking portion on the rotating shaft 21, the second locking portion can achieve locking cooperation with the first locking portion 41 of the movable member 4, thereby locking the movable member 4. The first locking portion 41 and the second locking portion can be constructed into any suitable structure capable of locking cooperation, and the present disclosure does not limit this.

[0052] For example, referring to Figure 3 and Figure 4 As shown in Figure 4 , a through groove 210 is recessed on the side wall of the rotating shaft 21; the rotating shaft 21 includes a first shaft section 211, a second shaft section 212, and a third shaft section 213. The second shaft section 212 connects the first shaft section 211 and the third shaft section 213, and the through groove 210 is disposed opposite to the second shaft section 212. The driving arm 22 is arranged on the first shaft section 211, and the first shaft section 211 and the third shaft section 213 are rotatably arranged on the mold frame; wherein, the second shaft section 212 is constructed as the second locking portion; when the locking body 2 is in the first movement position, the second shaft section 212 can be used for clamping with the first locking portion 41 constructed as a locking groove; when the locking body 2 is in the second movement position, the through groove 210 can be used to allow the movable member 4 to pass through movably.

[0053] In this embodiment, first, the first shaft section 211 and the third shaft section 213 are used to be rotatably arranged on the mold frame. That is, both ends of the rotating shaft 21 are rotatably arranged on the mold frame, which can ensure the stability of the rotation of the rotating shaft 21 on the mold frame. Secondly, by providing a through slot 210 on the side wall of the rotating shaft 21, when the locking body 2 is in the second movement position, the movable part 4 can movably pass through the through slot 210 to realize the unlocking of the movable part 4. In addition, when the locking body 2 is in the first movement position, the second shaft section 212 can be used to be clamped and abutted against the first locking part 41 configured as a locking slot, so as to realize the locking and limiting of the movable part 4. It should be noted that the second shaft section 212 can partially abut and be clamped against the inner wall of the locking slot or can entirely abut against the inner wall of the locking slot. For example, the second shaft section 212 can be a semi-shaft structure, and the cross-section of the first locking part 41 configured as a locking slot can be configured as a semi-circle.

[0054] Referring to Figure 2 As shown, the reset member 3 can include a reset spring 31, a mounting base 32, and a reset cable 33. The mounting base 32 is used to be arranged on the mold frame. The reset spring 31 is arranged on the mounting base 32. One end of the reset cable 33 is connected to the reset spring 31, and the other end is connected to the driving arm 22. Among them, the reset spring 31 can enable the locking body 2 to move from the first movement position to the second movement position; or the reset spring 31 can enable the locking body 2 to move from the second movement position to the first movement position.

[0055] In this embodiment, taking the example that the reset spring 31 can enable the locking body 2 to move from the second movement position to the first movement position. When it is necessary to unlock the movable part 4, the operator can drive the rotation of the rotating shaft 21 by pulling the cable 1, so that the above-mentioned through slot 210 is arranged opposite to the movable part 4, and the edge part of the movable part 4 can pass through the through slot 210. At this time, the reset spring 31 has a certain elastic potential energy. When the movable part 4 moves to the locked position, that is, when the locking slot on the movable part 4 is opposite to the locking body 2, the reset spring can apply an elastic force to the locking body 2 to drive its rotation, and make the second shaft section 212 be clamped in the locking slot, so as to realize the locking of the movable part 4. However, the present disclosure does not limit the specific structure of the reset member 3, and it can be configured as any appropriate structure.

[0056] In addition, referring to Figure 1 and Figure 2As shown, the locking body 2 may further include a locking seat 23 for being disposed on the die frame. The rotating shaft 21 is rotatably and axially locked to the locking seat 23. By providing the locking seat 23, the rotational stability of the rotating shaft 21 can be further improved. The present disclosure does not limit the specific installation method of the locking seat 23 on the die frame. For example, the locking seat 23 can be detachably connected to the die frame by means of bolt connection. In addition, for the axial limit setting of the rotating shaft 21, limit blocks can be provided at both ends of the rotating shaft 21 to achieve axial limit blocking, but the present disclosure does not limit the specific axial limit method.

[0057] Optionally, referring to Figure 1 and Figure 2 As shown, the cable 1 may include a cable body 11 and a pull ring 12. One end of the cable body 11 is connected to the pull ring 12, and the other end is connected to the locking body 2. The provision of the pull ring 12 facilitates the operator to perform the pulling operation and improves the operation convenience. In addition, the cable body 11 can be a flexible cable, which is convenient for the installation and layout of the cable routing.

[0058] In addition, referring to Figure 1 and Figure 2 As shown, the locking mechanism 100 further includes a limiting plate 5 and a plurality of fixing buckles 6. The fixing buckles 6 are used for being disposed on the die frame, and the fixing buckles 6 are formed with a through hole 60 for the cable body 11 to pass through; the limiting plate 5 is used for being disposed on the die frame and is formed with a limiting hole 50 for the cable body 11 to pass through, and the limiting plate 5 can limit the pull ring 12. By providing a plurality of fixing buckles 6, it is convenient to arrange and install the cable body 11, but the present disclosure does not limit the specific cable routing layout structure. In addition, the provision of the limiting plate 5 can expose the pull ring 12 outside the die frame, facilitating the operator to perform the pulling operation.

[0059] The present disclosure also provides a stamping die, which includes a die frame (not shown), a slider mechanism 200, and the above-mentioned locking mechanism 100. The slider mechanism 200 includes a driving member 7 and a movable member 4. The driving member 7 is disposed on the die frame and can drive the movable member 4 to move.
