[0035] In actual use, a product is placed on the lower stripping plate 400, and the upper die holder 100 in the upper mold drives the upper clamping plate, the upper stripping plate 200 and the upper mold plate 300 downward under the action of the punch press; the upper stripping plate 200 first contacts the product, and as the upper mold continues to move downward, the upper stripping plate 200 presses the middle part of the product, thereby driving the product to press the lower stripping plate 400, the lower mold plate 500 and the lower clamping plate 600 downward. At this time, the lower clamping plate 600 compresses the second elastic component 810 to move downward, and the side push component 30 moves relative to the lower mold plate 50 0 upward; during the upward movement of the side push component 30, the first forming block 900 is driven to move horizontally, so that the first forming block 900 extends outward, so that the first forming block 900 extends out and protects the straight edge of the side of the product together with the upper stripping plate 200; the lower clamping plate 600 moves to the position of the third elastic component 820 and presses against the third elastic component 820, the upper mold base 100 compresses the first elastic component 110 and moves downward, and the upper mold base 100 drives the upper mold plate 300 to interact with the first forming block 900 to complete the first One-time bending and forming; when the stroke of the first elastic component 110 is compressed, the upper mold drives the lower clamping plate 600 to compress the third elastic component 820, thereby driving the product to complete the second bending and forming under the joint action of the first molding block 900, the second molding block 710 and the upper template 300.

Technical problems.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] Example 1.

[0038] Please refer to Figures 1 to 11A multi-bending structure processing mold provided by an embodiment of the present invention comprises: an upper mold and a lower mold that are matched, the upper mold comprises an upper mold base 100 and an upper stripping plate 200 that are arranged in sequence, and the lower mold comprises a lower stripping plate 400, a lower template 500, a lower clamping plate 600, a lower pad 700 and a lower mold base 800 that are arranged in sequence.

[0039] In this embodiment, the upper mold base 100 is provided with a first elastic component 110, which abuts against the upper stripping plate 200, and the side of the upper mold base 100 is connected to the upper mold plate 300. That is, in actual use, when the upper stripping plate 200 is subjected to an upward force greater than the elastic force of the first elastic component 110, the upper stripping plate 200 will drive the first elastic component 110 to enter a compressed state, and at the same time, the upper mold base 100 will drive the upper mold plate 300 to move downward relative to the upper stripping plate 200, and then when the upper stripping plate 200 is subjected to an upward force less than the elastic force of the first elastic component 110, the upper stripping plate will move in the direction of returning to its original position under the elastic force of the first elastic component 110, and the upper mold base 100 will drive the upper mold plate 300 to move upward relative to the upper stripping plate 200, and the upper mold plate 300 can be fixedly connected to the lower side of the upper mold base 100 by screw connection, and the upper mold plate 300 can also be connected to the upper mold base 100 through a stop plate, which can be selected according to actual needs.

[0040] In this embodiment, the lower mold includes a lower stripping plate 400, a lower mold plate 500, a lower clamping plate 600, a lower pad 700 and a lower mold base 800 which are arranged in sequence. The lower mold base 800 is provided with a second elastic component 810 and a third elastic component 820. The second elastic component 810 abuts against the lower clamping plate 600. A suspended portion 10 is left between the third elastic component 820 and the lower clamping plate 600. The elastic forces of the second elastic component 810, the first elastic component 110 and the third elastic component 820 increase in sequence. Since the elastic forces of the second elastic component 810, the first elastic component 110 and the third elastic component 820 increase in sequence, under the action of the upper mold, it can be referred to Figure 6-Figure 7 The lower clamping plate 600 will first drive the second elastic component 810 to enter the compression process. Since a suspended portion 10 is left between the third elastic component 820 and the lower clamping plate 600, the lower clamping plate 600 will move within the travel of the suspended portion 10.

[0041] In this embodiment, the side of the lower template 500 is connected to the first molding block 900 through the fourth elastic component 20, and a side pushing component 30 is arranged between the lower template 500 and the first molding block 900. The first molding block 900 moves horizontally under the action of the side pushing component 30. When the lower clamping plate 600 moves downward, the side pushing component 30 will move upward relative to the lower clamping plate 600, the lower template 500 and the first molding block 900. The first molding block 900 moves horizontally under the upward action of the side pushing component 30, and the first molding block 900 extends outward. After completing the process of the suspended portion 50, the lower clamping plate 600 presses against the third elastic component 820, and the lower clamping plate 600 stops moving. At this time, the first molding block 900 and the upper release plate 200 together protect the straight edge of the product 40. It can be understood, please refer to Figure 2 The lower part of the side of the upper release plate 200 has a protecting portion 210, and the position of the protecting portion 210 is determined according to the position of the straight edge of the product 40. The protecting portion 210 of the upper release plate 200 and the first forming block 900 together protect the straight edge of the product 40 to prevent the straight edge of the product 40 from deformation during the stamping process.

[0042] For further information, see Figures 4 to 5 The side push component 30 has a first bevel portion 31 on the top side close to the first forming block 900, and the first forming block 900 has a second bevel portion 920 matching the first bevel portion 31 on the bottom side close to the side push component 30. When the side push component 30 moves upward, the first forming block 900 moves horizontally under the action of the first bevel portion 31 and the second bevel portion 920. The first bevel portion 31 and the second bevel portion 920 match each other in the vertical direction. Therefore, when the first bevel portion 31 moves upward, a force to move horizontally will be provided to the second bevel portion 920, so that the first forming block 900 extends outward. This bevel matching structure is simple to manufacture and is very convenient to install and use.

[0043] Furthermore, the side push component 30 is a structure with a narrow upper portion and a wide lower portion, and the maximum width of the gap portion clamping the side push component 30 between the first molding block 900 and the lower template 500 is smaller than the width of the widest portion of the lower portion of the side push component 30, wherein the transition portion from the narrow upper portion to the wide lower portion of the side push component 30 is an arc-shaped structure, and the side of the first molding block 900 close to the side push component 30 is a matching arc-shaped structure, when the wider position of the lower portion of the side push component 30 moves upward into the gap portion clamping the side push component 30 between the first molding block 900 and the lower template 500, the transition surface of the arc-shaped structure will make the side push component 30 enter the gap portion more smoothly, making it less likely to be damaged in the mold, of course, as needed, ball bearings can also be installed in the arc structure between the side push component 30 and the first molding block 900 to make the relative movement of the two smoother.

[0044] See also Figures 8 to 9In this embodiment, since the elastic force of the third elastic component 820 is greater than that of the first elastic component 110, the first elastic component 110 will enter the compressed state before the third elastic component 820. At this time, the lower clamping plate 600 continues to remain stationary, and the upper mold base 100 presses the first elastic component 110 to move downward, thereby driving the upper mold plate 300 to press the side of the product 40 to complete the first bending. It can be understood that please refer to Figure 2 A bevel pressing portion 310 is provided at the bottom of the upper template 300 near the lower stripping plate 400. The bevel pressing portion 310 is used to press a bevel on the product, that is, to complete the first bending.

[0045] In this embodiment, the lower pad 700 is provided with a second forming block 710, and the second forming block 710 is located below the upper template 300. When the compression stroke of the first elastic component 110 is completed, the lower clamping plate 600 begins to compress the third elastic component 820 under the action of the upper mold. At this time, the upper mold presses the product 40, the lower stripping plate 400, the lower template 500 and the lower clamping plate 600 to move downward together, see Figure 10 to Figure 11 The product 40 is pressed by the upper mold and moves downward, and then contacts the second forming block 710 . The product 40 completes the second bending under the joint action of the first forming block 900 , the second forming block 710 and the upper mold plate 300 .

[0046] In this embodiment, after completing the second bending, the upper mold moves upward to release the active product 40 and the lower mold. At this time, the lower clamp 600 moves upward under the elastic force of the second elastic component 810 and the third elastic component 820. At this time, the side push component 30 moves downward relative to the lower template 500, so that the side push component 30 releases its effect on the first molding block 900, and the first molding block 900 returns to its original position under the action of the fourth elastic component 20.

[0047] Example 2.

[0048] The difference between this embodiment and embodiment 1 is that, see Figure 3 A first right-angled first protrusion 910 is provided on one side of the top of the first forming block 900 close to the upper template 300, wherein the first right-angled side of the first protrusion 910 can match the inclination angle and position of the bevel pressing portion 310 of the upper template 300, so that the bevel pressing portion 310 can protect the bevel of the product when pressing the bevel on the product, and cooperate with the bevel pressing portion 310 to complete the first bending.

[0049] Furthermore, a second protrusion 711 is provided at a right angle on the top of the second molding block 710 near the first molding block 900. Fig.11, the product 40 is driven downward by the upper mold, and the second right-angled side of the first protrusion 910 cooperates with the two right-angled sides of the second protrusion and the beveled side 310 to complete the second bend, so that the product 40 is bent into a right angle shape for the second time. Here, the first right-angled side of the second protrusion 711 and the beveled side 310 complete one bend, and the second right-angled side of the second protrusion 711 and the second right-angled side of the first protrusion 910 complete another bend, and a total of two bends are completed. When producing products such as F-type structures, the process that previously required two stampings to complete is completed at one time, thereby effectively increasing production efficiency. The other structures and working principles of this embodiment are the same as those of Embodiment 1 and will not be described here.

[0050] Example 3.

[0051] The difference between this embodiment and embodiment 1 is that in this embodiment, please refer to Figure 1 The lower clamping plate 600 is fixed with an ejector spring 610, one end of which passes through the lower template 500 and the lower stripping plate 400. When the product 40 is pressed by the upper stripping plate 200, the product 40 will press the ejector spring 610 to make it enter a compressed state, and when the upper stripping plate 200 stops moving upward and exerts downward force on the product 40, the product 40 will be lifted up by the ejector spring 610, making it easier to strip the product 40. The other structures and working principles of this embodiment are the same as those of embodiment 1, and will not be described here.

[0052] An embodiment of the present invention further provides a method for using a multi-bending structure processing mold. Based on the multi-bending structure processing mold of any of the above-mentioned embodiments, the method specifically includes:

[0053] S100, in actual use, a product is placed on the lower stripping plate 400, and the upper die seat 100 in the upper die drives the upper clamping plate, the upper stripping plate 200 and the upper die plate 300 downward under the action of the punch press;

[0054] S200, the upper stripping plate 200 first contacts the product, and as the upper mold continues to move downward, the upper stripping plate 200 presses the middle of the product, thereby driving the product to press the lower stripping plate 400, the lower mold plate 500 and the lower clamping plate 600 downward. At this time, the lower clamping plate 600 compresses the second elastic component 810 to move downward, and the side push component 30 moves upward relative to the lower mold plate 500;

[0055] S300, during the upward movement of the side push component 30, the first forming block 900 is driven to move horizontally, so that the first forming block 900 extends outward, so that the first forming block 900 extends out and protects the straight edge of the side of the product together with the upper stripping plate 200; the lower clamping plate 600 moves to the position of the third elastic component 820 and abuts against the third elastic component 820, the upper mold base 100 compresses the first elastic component 110 and moves downward, and the upper mold base 100 drives the upper mold plate 300 to complete the first bending molding of the product in interaction with the first forming block 900;

[0056] S400, when the stroke of the first elastic component 110 is compressed, the upper mold drives the lower clamping plate 600 to compress the third elastic component 820, thereby driving the product to complete the second bending molding under the joint action of the first molding block 900, the second molding block 710 and the upper mold plate 300.

[0057] Furthermore, after the second bending forming is completed, the method of use also includes:
