Figure 1 , define the first direction as the X-axis direction, the second direction as the Y-axis direction, and the vertical direction as the Z-axis direction.

[0071] See also Figure 1 Some embodiments of the present application provide a shaping mold 100 for shaping a workpiece 200 (see Figure 5 ) shaping, the workpiece 200 has a special-shaped structure. For ease of understanding, the present application takes a workpiece 200 having a straight portion 201 and an arcuate portion 202 as an example for explanation. Of course, the workpiece 200 may also have other structures, which are not limited here. It can be understood that the arcuate portion 202 of the workpiece 200 is prone to deformation, resulting in a larger distance between the arcuate portion 202 and the straight portion 201, which affects subsequent processing and assembly. The shaping mold 100 includes an upper mold 10 and a lower mold 20.

[0072] Specifically, see Figure 1 , Figure 2 and Figure 3 The upper die 10 includes an upper die seat 11, a pair of push members 12 and a plurality of lower pressure columns 13. The upper die seat 11 is used to connect with an external driving device (not shown). The pair of push members 12 are arranged at intervals along the X-axis direction on the side of the upper die seat 11 away from the external driving device. The plurality of lower pressure columns 13 are all connected to the upper die seat 11 and are arranged on the same side of the upper die seat 11 as the push members 12. The upper die seat 11 can be a plate-like structure. The plate-like upper die seat 11 is convenient for connecting with an external driving device and can improve the stability of the connection between the push members 12 and the lower pressure columns 13 and the upper die seat 11. The external driving device can be a hydraulic cylinder, a punching machine, etc., which can drive the upper die 10 to move closer to or away from the lower die 20, and is not limited here. The push member 12 can be a block structure, and the lower pressure column 13 can be a columnar structure. The number can be four, six, etc., and the ends of the plurality of lower pressure columns 13 away from the upper die seat 11 are located on the same plane.

[0073] See also Figure 1 , Figure 4 , Figure 5 and Figure 6The lower mold 20 includes a fixed plate 21, a floating support assembly 22, a shaping member 23 and a pair of clamping assemblies 24. The fixed plate 21 is arranged corresponding to the upper mold base 11. The floating support assembly 22 is arranged on the side of the fixed plate 21 close to the upper mold base 11. The side of the floating support assembly 22 away from the fixed plate 21 is provided with a material storage groove 221 for carrying the workpiece 200. The shaping member 23 is rotatably connected to the side of the fixed plate 21 facing the floating support assembly 22, and is adjacent to the material storage groove 221 along the Y-axis direction. The shaping member 23 is used to abut the workpiece 200. A pair of clamping assemblies 24 are arranged at intervals on both sides of the material storage groove 221 along the X-axis direction, and are both slidably connected to the floating support assembly 22. The fixed plate 21 can be set as a plate-like structure, the floating support assembly 22 can include a plate-like structure and a plurality of sixth elastic members 25, and the area of ​​the fixed plate 21 is larger than the area of ​​the plate-like structure of the floating support assembly 22, the sixth elastic member 25 can be a spring, etc., and the number of the sixth elastic members 25 can be four, six, eight, etc., which can stably support the plate-like structure of the floating support assembly 22, and is not limited here. It can be understood that when no external force is applied, the sixth elastic member 25 supports the plate-like structure of the floating support assembly 22 and is spaced from the fixed plate 21 along the Z-axis direction. The material storage groove 221 is adapted to the structure of the workpiece 200. In one embodiment, the material storage groove 221 is used to accommodate the straight portion 201 of the workpiece 200. The shaping member 23 and the fixed plate 21 can be connected by a rotating shaft so that the shaping member 23 can move around the rotating shaft. It can be understood that the shaping member 23 rotates in the YZ plane. In one embodiment, when the straight portion 201 of the workpiece 200 is placed in the material receiving groove 221, the arc portion 202 of the workpiece 200 abuts against the shaping member 23. The pair of clamping assemblies 24 are both slidably connected to the floating support assembly 22 and can slide along the X-axis direction.

[0074] Please continue to read Figure 4 A pair of pushing members 12 push a pair of clamping assemblies 24 toward each other when the mold is closed, so that the pair of clamping assemblies 24 clamp the workpiece 200 located in the material receiving groove 221. A plurality of pressing columns 13 are used to abut the floating support assembly 22 after the clamping assembly 24 clamps the workpiece 200, so as to push the floating support assembly 22 to drive the workpiece 200 to move toward the fixed plate 21, and then the workpiece 200 drives the shaping member 23 to rotate so that the shaping member 23 shapes the workpiece 200.

[0075] In one embodiment, a first inclined surface 121 is provided on the relative inner sides of a pair of push members 12, and a second inclined surface 241 matching with the first inclined surface 121 is provided on a pair of clamping components 24. In this way, when the push members 12 move toward the clamping components 24, the first inclined surface 121 can abut against the second inclined surface 241, thereby pushing the clamping components 24 to move.

[0076] It can be understood that when the mold is closed, the upper mold 10 moves toward the lower mold 20, that is, the upper mold 10 moves in the opposite direction of the Z axis, and the first inclined surfaces 121 of the two pushing members 12 respectively abut against the first inclined surfaces 121 of the two clamping components 24. As the upper mold 10 continues to move in the opposite direction of the Z axis, the two pushing members 12 push the two clamping components 24 to move closer to each other, thereby causing the two clamping components 24 to clamp the straight portion 201 of the workpiece 200 located in the material receiving groove 221. When the two clamping assemblies 24 clamp the workpiece 200, the lower pressure column 13 abuts the floating support assembly 22, and then when the upper mold 10 continues to move in the opposite direction of the Z axis, the lower pressure column 13 pushes the floating support assembly 22 to move toward the fixed plate 21. At this time, the floating support assembly 22 drives the workpiece 200 to move in the opposite direction of the Z axis through the two clamping assemblies 24. The arc-shaped portion 202 of the workpiece 200 will push the shaping component 23 to rotate, and the shaping component 23 will shape and correct the arc-shaped portion 202 of the workpiece 200 during the rotation process.

[0077] The shaping mold 100 provided in the embodiment of the present application includes an upper mold 10 and a lower mold 20, wherein the lower mold 20 is provided with a material storage groove 221, which can carry the workpiece 200 to be shaped. During shaping, the upper mold 10 and the lower mold 20 are closed, and when the upper mold 10 moves toward the lower mold 20, a pair of push members 12 abut against a pair of material clamping components 24, and through the cooperation of the first inclined surface 121 and the second inclined surface 241, the pair of material clamping components 24 can be driven to approach each other and clamp the workpiece 200 located in the material storage groove 221. Then the lower pressure column 13 of the upper die 10 abuts against the floating support assembly 22 of the lower die 20, and then pushes the floating support assembly 22 to move downward. The floating support assembly 22 drives a pair of clamping assemblies 24 and the workpiece 200 to move downward. The position to be corrected of the workpiece 200 pushes the shaping member 23 to move. Since the shaping member 23 is rotatably connected to the fixed plate 21, the shaping member 23 performs a rotational motion at this time, and then pushes the position to be corrected of the workpiece 200 to rotate, so as to achieve the shaping correction of the workpiece 200. The shaping mold 100 provided in the embodiment of the present application can perform shaping correction on the workpiece 200, is easy to operate, and has a good shaping effect.

[0078] See also Figure 1 , Figure 5 and Figure 6 In some embodiments, each clamping assembly 24 includes a sliding seat 242 and a clamping block 243. Each sliding seat 242 is slidably connected to the floating support assembly 22 along the X-axis direction, and each clamping block 243 is slidably connected to the corresponding sliding seat 242 along the Y-axis direction. The sliding seat 242 and the floating support assembly 22 can be slidably connected by a slide rail, or by a projection and a slide groove. A sliding rod can be provided in the sliding seat 242, and the clamping block 243 is sleeved on the sliding rod, so that the clamping block 243 can be slidably connected to the sliding seat 242 while limiting the position of the clamping block 243 relative to the sliding seat 242.

[0079] See also Figure 1 , Figure 5 and Figure 6 In some embodiments, the shaping member 23 is provided with a first profiling portion 231, and the first profiling portion 231 is used to carry the workpiece 200. The second profiling portion 2431 is provided on opposite sides of the pair of clamping blocks 243, and the second profiling portion 2431 is used to cooperate with the first profiling portion 231 to clamp the workpiece 200. It can be understood that the first profiling portion 231 can be adapted to the structure of the arc portion 202 of the workpiece 200, so that when the workpiece 200 is placed, the arc portion 202 of the workpiece 200 can fit the first profiling portion 231. The second profiling portion 2431 can be adapted to the structure of the arc portion 202 of the workpiece 200, so that when the clamping block 243 clamps the workpiece 200, the second profiling portion 2431 can fit the workpiece 200. In this way, the first profiling portion 231 and the second profiling portion 2431 can cooperate to clamp the arc portion 202 of the workpiece 200.

[0080] See also Figure 5 , Figure 7 and Figure 8 In some embodiments, each clamping assembly 24 includes a first elastic member 244 and a second elastic member 245. The sixth elastic member 25 and the first elastic member 244 can both be springs.

[0081] The sliding seat 242 is provided with a receiving groove 2421, and the first elastic member 244 is disposed in the receiving groove 2421, and one end of the first elastic member 244 abuts against the groove wall of the receiving groove 2421, and the other end abuts against the floating support assembly 22, and the first elastic member 244 is used to push the sliding seat 242 away from the receiving groove 221 along the X-axis direction. It can be understood that the floating support assembly 22 can be provided with a structure such as a convex block located in the receiving groove 2421, and the first elastic member 244 extends along the X-axis direction and the two ends abut against the groove wall of the receiving groove 2421 and the convex block of the floating support assembly 22 respectively. In this way, when the mold is separated, the upper mold 10 is away from the lower mold 20, and the pushing member 12 is away from the clamping assembly 24. At this time, the first elastic member 244 pushes the sliding seat 242 in the clamping assembly 24 away from the receiving groove 221, thereby exposing the workpiece 200, which is convenient for taking out the workpiece 200.

[0082] It can be understood that a plurality of receiving grooves 2421 may be provided in each sliding seat 242 , and a first elastic member 244 is provided in each receiving groove 2421 , so that the stability of the first elastic member 244 pushing the sliding seat 242 to move can be improved.

[0083] The second elastic member 245 is disposed between the sliding seat 242 and the clamping block 243. One end of the second elastic member 245 abuts against the side of the clamping block 243 away from the shaping member 23, and the other end abuts against the sliding seat 242. The second elastic member 245 is used to push the clamping block 243 along the Y-axis direction to move toward the shaping member 23. By providing the second elastic member 245, the clamping block 243 can be elastically pushed toward the shaping member 23, so that the second profiling portion 2431 can cooperate with the first profiling portion 231 to clamp the workpiece 200.

[0084] A third elastic member 234 is further provided between the shaping member 23 and the fixing plate 21 , and the third elastic member 234 is used for pushing the shaping member 23 to return to its original position.

[0085] See also Figure 5 , Figure 6 and Figure 7 In some embodiments, a pusher 232 is provided at one end of the shaping member 23 close to the two clamping blocks 243. Both ends of the pusher 232 extend out of the shaping member 23 in the X-axis direction and are respectively provided corresponding to a pair of clamping blocks 243. Both ends of the pusher 232 are provided with first rollers 233, which are used to push the clamping blocks 243 when the shaping member 23 rotates toward the fixed plate 21. The pusher 232 may be a rod-shaped structure, which is convenient for connecting with the first roller 233. The first roller 233 may be a bearing or the like. By providing the pusher 232, the shaping member 23 can synchronously push the two clamping blocks 243 during the process of rotating to shape the workpiece 200, so that the first profiling portion 231 and the second profiling portion 2431 move synchronously, which is convenient for shaping the arc portion 202 of the workpiece 200. It can be understood that the shaping member 23 rotates in the YZ plane and the clamping block 243 moves in the XY plane. Therefore, when the shaping member 23 pushes the clamping block 243 to move, the shaping member 23 and the clamping block 243 will move relative to each other in the Z-axis direction. By providing the first roller 233 at both ends of the pushing member 232, the friction between the pushing member 232 and the shaping member 23 can be eliminated by the rotation of the first roller 233 when the pushing member 232 pushes the clamping block 243 to move.

[0086] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the upper mold base 11 includes an upper mold 10 plate for connecting to an external driving device and a connecting plate 112 connected to the upper mold 10 plate away from the external driving device, and a pair of push members 12 and a plurality of lower pressure columns 13 are connected to the side of the connecting plate 112 away from the upper mold 10 plate.

[0087] Please also read Figure 5The upper mold 10 also includes a pressing piece 14 and a fourth elastic piece 15. The pressing piece 14 is slidably connected to the connecting plate 112 and is arranged corresponding to the material storage groove 221. The pressing piece 14 is spaced apart from the clamping block 243 when the mold is closed. The fourth elastic piece 15 is arranged between the upper mold 10 plate and the pressing piece 14, and is used to elastically push the pressing piece 14 so that the pressing piece 14 elastically presses the workpiece 200 located in the material storage groove 221 when the mold is closed. One end of the pressing piece 14 arranged toward the material storage groove 221 is adapted to the structure of the material storage groove 221, and is adapted to the structure of the straight portion 201 of the workpiece 200 located in the material storage groove 221. The fourth elastic piece 15 can be a spring, etc. By setting the fourth elastic piece 15, the pressing piece 14 can elastically press the workpiece 200, avoiding the pressing piece 14 from rigidly contacting with the workpiece 200, resulting in damage to the workpiece 200. It can be understood that a plurality of fourth elastic members 15 can be provided to improve the stability of the fourth elastic member 15 in pushing and pressing the material member 14 .

[0088] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the upper mold 10 further includes a first limit member 16 , which is connected to a side of the connecting plate 112 away from the upper mold 10 , and is disposed adjacent to the pressing member 14 and corresponds to the clamping block 243 .

[0089] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, a pair of second rollers 17 are provided at one end of the first limit member 16 away from the connecting plate 112. The pair of second rollers 17 correspond to the pair of clamping blocks 243 respectively, and are used to abut the corresponding clamping blocks 243 when the mold is closed, thereby limiting the position of the clamping block 243 in the Z-axis direction. The second roller 17 can be a bearing, etc. It can be understood that when the mold is closed, the first limit member 16 moves toward the lower mold 20 with the connecting plate 112 until the pair of second rollers 17 connected to the first limit member 16 abut the pair of clamping blocks 243 respectively, so that the clamping block 243 can be limited in the Z-axis. By providing the second roller 17, the second roller 17 can rotate when the clamping block 243 moves along the Y-axis to avoid the friction between the first limit member 16 and the clamping block 243, which affects the movement of the clamping block 243.

[0090] See also Figure 1 , Figure 2 and Figure 5In some embodiments, the upper mold 10 further includes a plurality of positioning posts 18, which are all connected to the upper mold 10 plate and are arranged toward the fixed plate 21. The positioning posts 18 are used to abut against the fixed plate 21 during mold closing to position the upper mold 10. The number of positioning posts 18 can be two, four, etc. It can be understood that when the positioning posts 18 abut against the fixed plate 21, the upper mold 10 and the lower mold 20 complete the mold closing. At this time, the upper mold 10 no longer moves toward the lower mold 20, and the shaping member 23 no longer rotates. In this way, the amount of rotation shaping of the workpiece 200 by the shaping member 23 can be determined by the length of the positioning posts 18, so as to shape the workpiece 200 to a standard state.

[0091] The lower mold 20 also includes a plurality of adjustment components 26 corresponding to the positioning posts 18, each of which includes a positioning member 261, an adjustment member 262 and a fifth elastic member 263. The positioning member 261 is connected to the side of the fixed plate 21 facing the upper mold 10, the adjustment member 262 is movably sleeved on the positioning member 261, and the fifth elastic member 263 is sleeved on the positioning member 261 and abuts against the side of the adjustment member 262 away from the fixed plate 21, and is used to push the adjustment member 262 against the fixed plate 21. The number of the adjustment components 26 is consistent with the number of the positioning posts 18, such as two, four, etc., and the position of the adjustment component 26 corresponds to the position of the positioning post 18. The positioning member 261 can be a bolt, etc., and the adjustment member 262 can be an annular structure, sleeved on the positioning member 261, and can slide and rotate along the positioning member 261. The fifth elastic member 263 may be a spring, one end of which abuts against one end of the positioning member 261 away from the fixing plate 21 , and the other end of which abuts against the adjusting member 262 , so as to elastically hold the positioning member 261 against the fixing plate 21 .

[0092] A plurality of adjustment surfaces 2621 are provided on the side of the adjustment member 262 facing away from the fixed plate 21. The plurality of adjustment surfaces 2621 are at different distances from the fixed plate 21. The adjustment member 262 is used to rotate around the positioning member 261 to make different adjustment surfaces 2621 face the positioning column 18, and then adjust the position of the upper mold 10 from the lower mold 20 when the mold is closed by abutting the positioning column 18 against different adjustment surfaces 2621. The adjustment surfaces 2621 on the adjustment member 262 can be provided with four, five, six, etc. It can be understood that when in use, the adjustment surfaces 2621 of the same height of the plurality of adjustment members 262 are made to correspond to the positioning column 18. Specifically, the adjustment member 262 is moved a distance in the Z-axis direction, and then the adjustment member 262 is rotated to make the used adjustment surface 2621 face the positioning column 18, and then the adjustment member 262 is released, and the adjustment member 262 abuts against the fixed plate 21 under the push of the fifth elastic member 263. When the mold is closed, the positioning column 18 abuts the adjustment surface 2621 to limit the distance between the upper mold 10 and the lower mold 20. Therefore, by making the adjustment surfaces 2621 of different heights correspond to the positioning column 18, different distances between the upper mold 10 and the lower mold 20 can be set, and then various workpieces 200 can be shaped.

[0093] See also Figure 1 and Figure 5 In some embodiments, the lower mold 20 further includes a plurality of first guide members 27 and a plurality of second stop members 28 connected to the fixed plate 21 on one side close to the floating support assembly 22. The floating support assembly 22 is slidably connected to the plurality of first guide members 27 and the plurality of second stop members 28. The first guide member 27 is used to guide the floating support assembly 22 when the floating support assembly 22 moves close to or away from the fixed plate 21, and the second stop member 28 is used to limit the distance of the floating support assembly 22 away from the fixed plate 21. The first guide member 27 may be a columnar structure. By providing the first guide member 27, the position of the floating support assembly 22 in the Z-axis direction may be limited, thereby improving the accuracy of mold closing. The end of the second stop member 28 away from the fixed plate 21 may be provided with a sheet structure to stop the floating support assembly 22.

[0094] In some other embodiments, the upper mold 10 further includes a plurality of second guide members 19 connected to the upper mold base 11 on the side facing the fixed plate 21, and the fixed plate 21 is provided with a plurality of guide holes 29 corresponding to the second guide members 19, and the second guide members 19 are used to be inserted into the guide holes 29 during mold closing to position the upper mold 10. The second guide members 19 may be a columnar structure, and the structure of the guide holes 29 is adapted to the second guide members 19. By providing the second guide members 19 and the guide holes 29, the accuracy of the upper mold 10 when moving toward the lower mold 20 can be improved.

[0095] The working process of the shaping mold 100 provided in some embodiments of the present application is roughly as follows:

[0096] First, the upper mold 10 and the lower mold 20 are separated to expose the material groove 221, and then the workpiece 200 to be shaped is placed in the material groove 221. It can be understood that the straight portion 201 of the workpiece 200 is located in the material groove 221, and the arc portion 202 abuts against the first contouring portion 231 of the shaping piece 23.

[0097] Then, the molds are closed. The upper mold 10 moves toward the lower mold 20 under the drive of the external driving device. The second guide member 19 is first inserted into the guide hole 29 to locate the position of the upper mold 10. The upper mold 10 continues to move to the lower mold 20. The first inclined surfaces 121 of the pair of push members 12 respectively abut against the second inclined surfaces 241 of the pair of clamping components 24. The push members 12 push the sliding seat 242 to move through the cooperation of the first inclined surfaces 121 and the second inclined surfaces 241, thereby making the pair of clamping components 24 move closer to each other until the second profiling portion 2431 cooperates with the first profiling portion 231 to clamp the arc portion 202 of the workpiece 200. At this time, the pressing member 14 abuts against the straight portion 201 of the workpiece 200 located in the material storage groove 221, the pair of second rollers 17 of the first stopper 16 abut against the pair of clamping blocks 243 respectively, and the lower pressing column 13 abuts against the floating support component 22.

[0098] The upper die 10 continues to move toward the lower die 20. During this process, the lower pressure column 13 pushes the floating support assembly 22 to move toward the fixed plate 21. The floating support assembly 22 drives the clamping assembly 24 to move synchronously, and the arc portion 202 of the workpiece 200 pushes the shaping member 23 to move. Since the shaping member 23 is rotatably connected to the fixed plate 21, the shaping member 23 rotates counterclockwise on the YZ plane during this process, thereby shaping and correcting the workpiece 200 until the positioning column 18 abuts against the adjustment surface 2621 of the adjustment member 262, and the shaping is completed.

[0099] After the shaping is completed, the external drive setting drives the upper mold 10 away from the lower mold 20. After the upper mold 10 is separated from the lower mold 20, the sixth elastic member 25 drives the floating support assembly 22 to reset, the first elastic member 244 drives the sliding seat 242 to reset, and the second elastic member 245 drives the clamping block 243 to reset, thereby causing the clamping assembly 24 to release the workpiece 200, so that the shaped workpiece 200 can be taken out.
