[0074] The embodiments of the present application are further described below in conjunction with the accompanying drawings.
[0075] like Figures 1 to 4 As shown, an embodiment of the present application provides a bending mold 100 for bending and shaping a product 200, comprising a first mold group 10 and a second mold group 20. The first mold group 10 can be used to place the product 200, and the second mold group 20 moves close to the first mold group 10 and cooperates with the first mold group 10 to bend and shape the product 200. After the product 200 is bent and shaped, the second mold group 20 moves in a direction away from the first mold group 10 and separates from the first mold group 10. At this time, the shaped product 200 can be transferred out of the bending mold 100.
[0076] In one embodiment, the first module 10 includes a first base 11 and a contour seat 12 disposed on the first base 11 . The contour seat 12 is provided with a receiving portion 121 . The receiving portion 121 is used to receive the product 200 to be processed.
[0077] In one embodiment, the second die set 20 includes a second base 21, a pressing assembly 22 and a rolling assembly 23, and the pressing assembly 22 and the rolling assembly 23 are arranged on the second base 21. The second base 21 is connected to an external power device, and under the action of the external power device, the second base 21 can drive the pressing assembly 22 and the rolling assembly 23 to move vertically to move closer to or away from the first die set 10 to complete the bending and shaping of the product 200. The vertical direction refers to Figure 3 The up and down directions in .
[0078] The pressing assembly 22 includes a pressing plate 221 and a first elastic assembly 222 . The first elastic assembly 222 connects the pressing plate 221 and the second base 21 , so that the pressing plate 221 is elastically connected to the second base 21 and can elastically move relative to the second base 21 in the vertical direction.
[0079] The pressing plate 221 and the profiling seat 12 are arranged opposite to each other in the vertical direction. When the second die set 20 and the first die set 10 are close to each other, the pressing plate 221 moves close to the profiling seat 12, and the pressing plate 221 can press the product 200 to be processed in the accommodating portion 121 against the limit position to reduce the risk of the product 200 shaking or moving.
[0080] The rolling assembly 23 is obliquely disposed on one side of the pressing plate 221 . When the second die set 20 and the first die set 10 are close to each other, the rolling assembly 23 is used to obliquely roll the product 200 to be processed so as to bend and shape the product 200 .
[0081] The rolling assembly 23 includes a rolling seat 231 , a second elastic assembly 232 , a connecting member 233 and a rolling member 234 .
[0082] The rolling seat 231 is disposed on the second base 21, and the second base 21 can drive the rolling assembly 23 to move synchronously through the rolling seat 231. The connecting member 233 is movably connected to the rolling seat 231, and the second elastic component 232 connects the rolling seat 231 and the connecting member 233. Under the action of the second elastic component 232, the connecting member 233 can be elastically moved relative to the rolling seat 231.
[0083] The rolling member 234 rotates to connect the connecting member 233. When the second module 20 and the first module 10 approach each other, the rolling member 234 contacts and connects the product 200 to be processed. Through the second elastic component 232 and the connecting member 233, the rolling member 234 realizes elastic oblique rolling and shaping of the product 200 to be processed, which is beneficial to reduce the risk of cracking or rebound of the product 200, and reduce the risk of the surface of the product 200 being damaged by compression, thereby improving the shaping quality of the product 200.
[0084] In one embodiment, there are two rolling assemblies 23, which are respectively located on both sides of the pressing plate 221 in the horizontal direction. The two rolling assemblies 23 cooperate with each other to bend and shape the two ends of the product 200 to be processed. Figure 3 The left and right direction in .
[0085] In one embodiment, the rolling assembly 23 further includes a bottom plate 235, which connects the rolling seat 231 and the second elastic assembly 232. The bottom plate 235 can support and limit the second elastic assembly 232. When the rolling assembly 23 rolls the product 200, the support of the bottom plate 235 is conducive to reducing the risk of the second elastic foot 232 moving relative to the rolling seat 231, so that the second elastic assembly 232 provides stable elastic support for the rolling member 234.
[0086] like Figures 4 to 7 As shown, in one embodiment, the rolling seat 231 has a cavity 236 , the second elastic component 232 is disposed in the cavity 236 , and at least a portion of the connecting member 233 is disposed in the cavity 236 .
[0087] In one embodiment, the connecting member 233 is provided with a guide groove 2331, and the rolling assembly 23 further includes a guide member 237, the guide member 237 is connected to the rolling seat 231, and a portion of the guide member 237 is inserted into the guide groove 2331. The guide member 237 is connected to the rolling seat 231 and inserted into the guide groove 2331, which can guide the movement of the connecting member 233 relative to the rolling seat 231, improve the stability and accuracy of the movement of the connecting member 233 relative to the rolling seat 231, and improve the quality of the rolling plastic product 200 by the rolling member 234.
[0088] Furthermore, the length of the guide groove 2331 is limited, and the guide member 237 inserted into the guide groove 2331 can also limit the movement of the connecting member 233 relative to the rolling seat 231, thereby reducing the risk of the connecting member 233 moving out of the cavity 236.
[0089] In one embodiment, the rolling seat 231 defines a through hole 2311 , the through hole 2311 is connected to the receiving cavity 236 , and the guide member 237 is disposed in the through hole 2311 .
[0090] In one embodiment, the rolling member 234 has a cylindrical structure, which is conducive to its rotation and rolling of the product 200, reduces the impact of the rolling process on the surface of the product 200, and improves the processing quality of the product 200.
[0091] In one embodiment, the rolling assembly 23 further includes a bearing 238, and the bearing 238 connects the rolling member 234 and the connecting member 233. The bearing 238 is provided to reduce the wear between the rolling member 234 and the connecting member 233, improve the smoothness of the rotation of the rolling member 234, and further reduce the impact of the rolling member 234 on the surface of the product 200.
[0092] In one embodiment, the direction in which the connecting member 233 moves relative to the rolling seat 231 forms an acute angle with the direction in which the second module 20 moves relative to the first module 10. When the connecting member 233 drives the rolling member 234 to roll the product 200, under the action of the second elastic component 232, the rolling member 234 elastically presses the product 200 in an oblique direction, which is conducive to bending and shaping the product 200.
[0093] In one embodiment, the angle between the direction in which the connecting member 233 moves relative to the rolling seat 231 and the direction in which the second die set 20 moves relative to the first die set 10 is 45°±5°.
[0094] In one embodiment, the second elastic component 232 is a nitrogen spring. The nitrogen spring is an elastic component that uses high-pressure nitrogen as the working medium. It has the advantages of small size, large elastic force, long stroke, stable operation, precise manufacturing, long service life (one million times), flat elastic force curve, and no need for pre-tightening, etc. It is beneficial to the installation and adjustment of the second module 20, prolong the service life of the bending mold 100, and improve the stability of the processing quality of the product 200.
[0095] In one embodiment, the first elastic component 222 is a nitrogen spring, which is beneficial to the installation and adjustment of the second module 20, prolongs the service life of the bending die 100, and improves the stability of the processing quality of the product 200.
[0096] like Figure 1 , Figure 8 and Fig. 9 As shown, in one embodiment, the profiling seat 12 is provided with two accommodating portions 121, and the profiling seat 12 can accommodate two products 200 at the same time, so that the bending mold 100 can shape the two products 200 at the same time, which is conducive to improving processing efficiency. In one embodiment, the number of accommodating portions 121 on the profiling seat 12 can also be three, four or more.
[0097] In one embodiment, the profiling seat 12 is provided with a through slot 122 penetrating in the vertical direction, and the first module 10 further comprises a profiling block 13, which is arranged in the through slot 122, and the profiling block 13 and the profiling seat 12 form the receiving portion 121. Through the split design of the profiling block 13 and the profiling seat 12, by replacing different profiling blocks 13, receiving portions 121 of different shapes can be formed, so that the product 200 can be processed into different shapes, which is conducive to improving the compatibility of the profiling seat 12 with different processing requirements and reducing the manufacturing cost of the bending mold 100.
[0098] like Figure 1 and Figure 3 As shown, in one embodiment, the first module 10 also includes a positioning component 14, which is disposed on the first base 11. The positioning component 14 is used to position the product 200 to be processed so that the product 200 to be processed is located at a preset processing position, which is beneficial to improving the processing quality of the bending mold 100 on the product 200.
[0099] In one embodiment, the positioning assembly 14 includes a first positioning member 141 . The first positioning member 141 and the accommodating portion 121 are disposed opposite to each other in the lateral direction. The first positioning member 141 is used to limit the lateral movement of the product 200 in the accommodating portion 121 .
[0100] The first positioning member 141 is provided with a guide surface 1411, which faces the accommodating portion 121. When the product 200 is placed in the accommodating portion 121, the guide surface 1411 can be used to contact and connect the product 200 and guide the product 200 to move into the accommodating portion 121, which is beneficial to improve the placement accuracy of the product 200 in the accommodating portion 121, thereby improving the processing quality of the bending mold 100 on the product 200.
[0101] In one embodiment, there are two positioning components 14, which are located on both sides of the contour seat 12. The two positioning components 14 cooperate to clamp the product 200 to be processed, which is beneficial to further improve the guiding and positioning effect of the product 200 and improve the processing quality of the bending mold 100 on the product 200.
[0102] In one embodiment, in the two positioning assemblies 14 , the guide surfaces 1411 on the two first positioning members 141 cooperate to form a trumpet shape that is larger at the top and smaller at the bottom, so as to guide the product 200 to move to a preset position in the accommodating portion 121 .
[0103] like Figure 1 , Figure 4 , Figures 9 to 11 As shown, in one embodiment, the positioning assembly 14 further includes a second positioning member 142 and a spring 143, and the spring 143 connects the first positioning member 141 and the second positioning member 142. The spring 143 is used to act on the first positioning member 141 in a direction toward the accommodating portion 121, so that the first positioning member 141 has a tendency to move toward the accommodating portion 121, so as to elastically clamp the large product 200 located in the accommodating portion 121, which is conducive to reducing the risk of the product 200 being damaged by the first positioning member 141.
[0104] In one embodiment, the spring piece 143 may also be a compression spring.
[0105] In one embodiment, the second positioning member 142 has a groove 1422 (such as Figure 4 As shown in FIG. 1 , at least part of the first positioning member 141 and the spring sheet 143 are disposed in the groove 1422, and the spring sheet 143 connects the side wall of the groove 1422 and the first positioning member 141. The groove 1422 can limit the movement of the first positioning member 141 and the third spring, which is beneficial to improving the guiding and positioning effect of the product 200.
[0106] In one embodiment, the second positioning member 142 is movably connected to the first base 11. When the second module 20 is stamped close to the profiling seat 12, the rolling seat 231 is connected to the second positioning member 142 and drives the second base 21 to move synchronously. During this process, the rolling member 234 bends and shapes the product 200 so that part of the product 200 is attached to the profiling block 13.
[0107] In one embodiment, the positioning assembly 14 further includes a mold spring 144 , which connects the second positioning member 142 and the first base 11 . The mold spring 144 can apply a force to the second positioning member 142 in a direction toward the rolling seat 231 .
[0108] After the second module 20 bends and deforms the product 200, the second module 20 moves in a direction away from the first module 10. At this time, the pressure of the rolling seat 231 on the second positioning member 142 decreases or disappears. Under the action of the mold spring 144, the second positioning member 142 moves in a direction away from the first base 11 and resets.
[0109] In one embodiment, the mold spring 144 is a compression spring.
[0110] In one embodiment, the second positioning member 142 includes a protrusion 1421 (eg Figure 4 As shown in the figure, the convex part 1421 is extended in the direction toward the accommodating part 121. After the second module 20 bends and deforms the product 200, the second positioning member 142 moves in the direction away from the first base 11, and the convex part 1421 moves to a position facing the bent part of the product 200 in the transverse direction, and connects the bent part of the product 200. At this time, the convex part 1421 can limit the rebound of the bent part of the product 200, reduce the risk of rebound of the product 200, and the convex part 1421 can also maintain a good flatness of the bent part of the product 200 by connecting the bent part of the product 200, thereby improving the shaping quality of the product 200.
[0111] In one embodiment, the first module 10 further includes a base 15 and a cushion block 16 . The first base 11 and the base 15 are arranged opposite to each other in the vertical direction. The cushion block 16 is arranged between the first base 11 and the base 15 and connects the first base 11 and the base 15 .
[0112] like Figure 1 and Figure 2 As shown, in one embodiment, one of the first module 10 and the second module 20 includes a guide column 25, and the other of the first module 10 and the second module 20 includes a guide sleeve 17. When the first module 10 and the second module 20 move toward each other, part of the guide column 25 can be inserted into the guide sleeve 17. The plug-in fit between the guide column 25 and the guide sleeve 17 is helpful to improve the accuracy and stability of the relative movement between the first module 10 and the second module 20, thereby improving the shaping quality of the product 200.
[0113] In one embodiment, the guide post 25 is disposed on the second base 21 , and the guide sleeve 17 is disposed on the first base 11 .
[0114] In one embodiment, there are multiple guide posts 25 and guide sleeves 17 , and their positions correspond one to one, which is beneficial to improving the stability and accuracy of the mutual movement between the first module 10 and the second module 20 .
[0115] In one embodiment, the first module 10 further includes a first stopper 18, which is disposed on the first base 11. When the first module 10 and the second module 20 move toward each other, the first stopper 18 is used to connect the second module 20 and limit the movement of the first module 10 and the second module 20 toward each other, thereby reducing the influence of excessive movement of the first module 10 and the second module 20 toward each other on the product 200.
[0116] In one embodiment, the second module 20 further includes a second stopper 26, which is disposed on the second base 21. When the first module 10 and the second module 20 move toward each other, the second stopper 26 is used to connect with the first stopper 18, which is beneficial to reduce the influence of excessive movement of the first module 10 and the second module 20 toward each other on the product 200.
[0117] In one embodiment, there are multiple first limiting members 18 and second limiting members 26 , and their positions correspond one to one, which is beneficial to improving the reliability of the mutual limiting between the first module 10 and the second module 20 .
[0118] To sum up, in the bending mold 100 of the present application, when the first module 10 and the second module 20 are close to each other to shape the product 200, the pressure plate 221 elastically presses against the product 200 to limit and fix the product 200, thereby reducing the risk of shaking or moving of the product 200. The connecting part 233 is connected by the second elastic component 232, so that the rolling part 234 elastically rolls the product 200, which is beneficial to reduce the risk of cracking or rebounding of the product 200, as well as reducing the risk of the surface of the product 200 being damaged by compression, thereby improving the shaping quality of the product 200.
