[0032] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.
[0033] This utility model provides a die-cutting mold 100. Please refer to [link / reference]. Figures 1 to 5 , Figure 1 This is a three-dimensional structural schematic diagram of the die-cutting mold 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 Side view of the die-cutting mold 100; Figure 3 yes Figure 1 A schematic diagram of the structure of the supporting mechanism 10, the punch 21, and the die 22; Figure 4 yes Figure 3 A schematic diagram of the structure of the die 22; Figure 5 yes Figure 3 A schematic diagram of the structure of the punch 21 and die 22 is shown. The die-cutting mold 100 includes a supporting mechanism 10 and a forming mechanism 20. The supporting mechanism 10 is used to support the first strip 200; the forming mechanism 20 includes a die 22 and a punch 21 arranged opposite to each other. The die 22 has a punching hole 221 that passes through the die 22 and is used to support the second strip 300, such that the second strip 300 covers the punching hole 221. The supporting mechanism 10 is located on one side of the punching hole 221. The punch 21 and the die 22 are movably connected. The punch 21 can move relative to the die 22 and extend into the punching hole 221 to punch a portion of the second strip 300 to form a first component 400, and push the first component 400 through the punching hole 221 to combine with the first strip 200.
[0034] Specifically, the supporting mechanism 10, the die 22 and the punch 21 are arranged in sequence along the Z direction. The side of the supporting mechanism 10 facing the die 22 can carry the first material strip 200 conveyed along the X direction. The side of the die 22 away from the supporting mechanism 10 can be used for the passage of the second material strip 300 conveyed along the X direction. When the second material strip 300 passes through the die 22, it covers the punching hole 221. The punching hole 221 penetrates the die 22 along the Z direction.
[0035] Understandably, the punch 21 can extend into the punching hole 221 along the Z direction to punch a portion of the second strip 300 to form the first component 400, and can push the first component 400 along the Z direction through the punching hole 221 to be combined with the first strip 200. The punch 21 can reciprocate relative to the die 22 along the Z direction, and the first strip 200 and the second strip 300 are fed at intervals along the X direction to the carrying mechanism 10 and the die 22, respectively, so that the die-cutting die 100 can combine the first component 400 at multiple positions of the first strip 200 spaced apart along the X direction.
[0036] In this invention, the die-cutting mold 100, when the punch 21 moves, can work with the punching hole 221 on the die 22 to punch the second strip 300 to form the first component 400. It can also directly push the first component 400 onto the first strip 200 through the punching hole 221 and combine the first component 400 with the first strip 200. This eliminates the need for a transfer mechanism to combine the first component 400 with the first strip 200, thereby improving production efficiency.
[0037] In one embodiment of this implementation, please refer to Figures 1 to 3 , Figure 6 , Figure 6 yes Figure 1 A schematic diagram of the structure of the pressure member 23. The forming mechanism 20 also includes the pressure member 23, which is located on the side of the die 22 away from the bearing mechanism 10. The pressure member 23 is connected to the punch 21. The punch 21 can move relative to the die 22 in a first direction to extend into the punching hole 221 and drive the pressure member 23 to approach the die 22 in the first direction. The pressure member 23 is used to abut against the second strip 300.
[0038] Specifically, the plane perpendicular to the Z direction is defined as the XY plane. The projection of the pressure member 23 on the XY plane does not coincide with the projection of the punching hole 221 on the XY plane. It is understandable that during the process of the punch 21 extending into the punching hole 221, the punch 21 contacts the second strip 300 and may drive the second strip 300 to move, causing the second strip 300 to be misaligned, thereby affecting the dimensional accuracy of the first part 400 formed by punching. By setting the pressure member 23, during the process of the punch 21 extending into the punching hole 221, the pressure member 23 can abut against the second strip 300 and work with the punch 21 to press and fix the second strip 300, thereby helping to improve the dimensional accuracy of the first part 400.
[0039] In one embodiment of this implementation, please refer to Figures 1 to 3 , Figure 7 , Figure 7 yes Figure 1 The diagram shows the structure of the punch 21 and the first positioning component 24. The forming mechanism 20 also includes the first positioning component 24, which is connected to and fixed relative to the punch 21. The first positioning component 24 is used to extend into the hole on the first strip 200 to position the first strip 200.
[0040] Specifically, the forming mechanism 20 also includes a top plate 29, which is located on the side of the die 22 opposite to the supporting mechanism 10. The first positioning component 24 includes multiple pins extending along the Z direction. The punch 21 and the pins are both fixed on the top plate 29. It can be understood that the first positioning component 24 can move synchronously with the punch 21. When the punch 21 moves along the Z direction, the first positioning component 24 can extend into the hole on the first strip 200 along the Z direction to restrict the movement of the first strip 200 in the X and Y directions. This helps to ensure that the relative position of the punch 21 and the first strip 200 meets expectations, thereby enabling the first component 400 to be more accurately positioned on the first strip 200.
[0041] In one embodiment of this implementation, please refer to Figures 1 to 3 The forming mechanism 20 also includes a first elastic element 25, a pressure member 23 and a punch 21 that can be movably connected in a first direction, one end of the first elastic element 25 is connected to the first positioning component 24 and the other end is connected to the pressure member 23, and the first elastic element 25 can push the pressure member 23 toward the die 22.
[0042] Specifically, the first elastic element 25 is a spring, with one end connected to the top plate 29 and the other end connected to the pressure member 23. It can be understood that, on the one hand, during the process of the punch 21 extending into the punching hole 221, the pressure member 23 abuts against the second strip 300, and the first elastic element 25 is compressed. This allows the first elastic element 25 to provide a buffer during the contact process between the pressure member 23 and the second strip 300, reducing the risk of damage to the second strip 300. On the other hand, during the process of the punch 21 withdrawing from the punching hole 221, the first elastic element 25 extends and pushes the pressure member 23 towards the die 22, allowing the pressure member 23 to maintain a state of pressing the second strip 300 tightly. This reduces the risk of the second strip 300 being misaligned when the punch 21 withdraws from the punching hole 221.
[0043] In one embodiment of this implementation, please refer to Figures 1 to 3 The forming mechanism 20 also includes a second elastic element 26, which is mounted on the pressure member 23. When the punch 21 moves, the second elastic element 26 can push the die 22 toward the bearing mechanism 10 so that the die 22 abuts against the first strip 200.
[0044] Specifically, the second elastic element 26 is a spring, and multiple second elastic elements 26 are provided, with the multiple second elastic elements 26 arranged at intervals.
[0045] Understandably, when the die 22 moves toward the support mechanism 10 along the Z direction, the second elastic member 26 pushes the die 22 toward the support mechanism 10, so that the die 22 abuts against the first strip 200 on the support mechanism 10 and presses the first strip 200 tightly. The opening of the punching hole 221 facing the support mechanism 10 is covered by the first strip 200. At this time, the die 22 continues to move along the Z direction, the second elastic member 26 is compressed, and the punch 21 and the die 22 move relative to each other to punch the second strip 300 to form the first component 400, and then push the first component 400 through the punching hole 221 to combine with the first strip 200. This arrangement allows the first component 400 to be more accurately positioned on the first strip 200.
[0046] In one embodiment of this implementation, please refer to Figure 2 and Figure 6 The pressure member 23 is provided with a second positioning component 27, which is located between the die 22 and the pressure member 23. When the pressure member 23 moves toward the die 22, the second positioning component 27 is used to extend into the hole on the second strip 300 to position the second strip 300.
[0047] Specifically, the second positioning component 27 is a protrusion provided on the pressure member 23, and the second positioning component 27 extends along the Z direction.
[0048] It is understandable that the second positioning component 27 can move synchronously with the pressure member 23. When the pressure member 23 moves closer to the die 22 in the Z direction, the second positioning component 27 can extend into the hole on the second strip 300 in the Z direction to restrict the movement of the second strip 300 in the X and Y directions. This can reduce the risk of misalignment of the second strip 300 when the punch 21 punches it, thereby improving the dimensional accuracy of the first component 400.
[0049] In one embodiment of this implementation, please refer to Figure 2 , Figure 5 and Figure 6 The pressure member 23 has a guide hole 231. The guide hole 231 passes through the pressure member 23 and its axis is parallel to the first direction. The punch 21 passes through the guide hole 231 and can slide with the hole wall of the guide hole 231 along the first direction.
[0050] Specifically, the projection of the guide hole 231 in the XY plane coincides with the projection of the punching hole 221 in the XY plane. It can be understood that the guide hole 231 can position the punch 21, which helps to reduce the risk of the punch 21 shifting, thereby improving the dimensional accuracy of the first component 400.
[0051] In one embodiment of this implementation, please refer to Figures 3 to 5 A limiting member 28 is provided on the die 22. The limiting member 28 extends along a second direction, which is perpendicular to the first direction. The limiting member 28 is used to abut against the second strip 300 to provide guidance for the second strip 300 along the second direction.
[0052] Specifically, the limiting member 28 is located between the die cavity 22 and the pressure member 23, and the limiting member 28 is bolted to the die cavity 22. It can be understood that during the process of the second strip 300 being conveyed along the X direction on the die cavity 22, the limiting member 28 can remain in contact with the second strip 300 to restrict the movement of the second strip 300 along the Y direction, which helps to reduce the risk of misalignment of the second strip 300.
[0053] In one embodiment of this implementation, please refer to Figures 2 to 5 The limiting member 28 extends along a third direction and forms a pressing surface 281 perpendicular to the first direction. The third direction is perpendicular to the first and second directions. The pressing surface 281 is used to restrict the second material strip 300 from moving away from the bearing mechanism 10 along the first direction.
[0054] Specifically, the third direction is parallel to the Y direction, and the pressure surface 281 is parallel to the XY plane. The pressure surface 281 is located on the side of the die 22 away from the supporting mechanism 10, and the pressure surface 281 and the die 22 are spaced apart and opposite to each other. The gap between the pressure surface 281 and the die 22 is used for the feed strip to pass through. It can be understood that during the process of the punch 21 retracting from the punching hole 221, the punch 21 may drive the second feed strip 300 to move away from the supporting mechanism 10. The pressure surface 281 can restrict the movement of the second feed strip 300 away from the supporting mechanism 10, which helps to reduce the risk of misalignment of the second feed strip 300.
[0055] In one embodiment of this implementation, please refer to Figure 2 , Figure 5 and Figure 6 The pressure member 23 has a relief groove 232 with the opening of the relief groove 232 facing the die 22. When the pressure member 23 approaches the die 22, the limiting member 28 can extend into the relief groove 232.
[0056] Specifically, a portion of the pressure member 23 is recessed along the Z-direction away from the die 22 to form a relief groove 232, and the shape of the relief groove 232 is adapted to the shape of the limiting member 28. It is understandable that during the process of the pressure member 23 approaching the die 22, the limiting member 28 may interfere with the pressure member 23, causing the pressure member 23 to fail to press and fix the second strip 300. By providing the relief groove 232 on the pressure member 23, on the one hand, it helps reduce the risk of interference between the limiting member 28 and the pressure member 23; on the other hand, when the limiting member 28 extends into the relief groove 232, it can cooperate with the groove wall of the relief groove 232 to restrict the movement of the pressure member 23 along the X and Y directions, thereby further improving the fixing effect of the pressure member 23 on the second strip 300.
[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
