Composite hardware mold

Abstract

The application provides a composite hardware die, which comprises a driving mechanism, an upper die mechanism and a lower die mechanism. The lower die mechanism is arranged on a bearing table. The driver drives the upper die mechanism to move close to or away from the lower die mechanism. In the working process of the composite hardware die, a hardware plate to be punched is placed on the lower die mechanism. The driver drives the upper die mechanism to move close to the lower die mechanism to complete the punching forming work. In this process, each limiting slide column passes through a linear bearing to limit the running track of the upper die mechanism, thereby increasing the working stability of the composite hardware die. The punching upper die is connected with the upper die bearing table through two fixing assemblies, and the position of the punching upper die is adjusted through two adjusting assemblies to adapt to the position of the lower die mechanism.

[0022] Please refer to the following: Figures 1 to 5 The present invention provides a composite hardware mold 10, which includes a driving mechanism 100, an upper mold mechanism 200 and a lower mold mechanism 300.

[0023] The drive mechanism 100 includes a support platform 110, a connecting platform 120, a driver 130, and a plurality of limiting slide pins 140. The driver 130 is connected to the support platform 110 through the connecting platform 120. One end of each limiting slide pin 140 is connected to the driver 130, and the other end of each limiting slide pin 140 is connected to the support platform 110.

[0024] The lower mold mechanism 300 is mounted on the support platform 110. In this embodiment, the driver 130 is a hydraulic press. The driver 130 drives the upper mold mechanism 200 to move closer to or further away from the lower mold mechanism 300.

[0025] The upper die mechanism 200 includes a receiving plate 210, an upper die receiving platform 220, a stamping upper die 230, two fixing components 240, and two adjusting components 250. The driving end of the driver 130 is connected to the middle area of ​​one side of the receiving plate 210. A plurality of limiting sliding holes 201 are evenly distributed around the receiving plate 210. Linear bearings 211 are installed in the limiting sliding holes 201 of the receiving plate 210. The linear bearings 211 are adapted to the limiting sliding pins 140, with each limiting sliding pin 140 corresponding to a linear bearing 211. The upper die receiving platform 220 is connected to the middle area of ​​the side of the receiving plate 210 facing away from the driver 130. The stamping upper die 230 is connected to the upper die receiving platform 220 through the two fixing components 240, and the position of the stamping upper die 230 is adjusted by the two adjusting components 250.

[0026] During operation, the composite hardware mold 10 places the metal sheet to be stamped onto the lower mold mechanism 300. The driver 130 drives the upper mold mechanism 200 to move closer to the lower mold mechanism 300 to complete the stamping operation. In this process, each limiting slide post 140 passes through a linear bearing 211 to limit the running trajectory of the upper mold mechanism 200 and increase the working stability of the composite hardware mold 10. The stamping upper mold 230 is connected to the upper mold receiving platform 220 through two fixed components 240, and the position of the stamping upper mold 230 is adjusted by two adjusting components 250 to adapt to the position of the lower mold mechanism 300.

[0027] To facilitate the installation and disassembly of the stamping upper die 230, in one embodiment, the upper die receiving platform 220 has a first insertion slot 202 and two second insertion slots 203 on the side facing away from the receiving plate 210. The two second insertion slots 203 are symmetrically located on both sides of the first insertion slot 202. Insertion holes 204 are provided on both parallel sidewalls of the upper die receiving platform 220, and each second insertion slot 203 communicates with the first insertion slot 202 through a corresponding insertion hole 204. Two threaded holes 205 are provided on the side of the upper die receiving platform 220 facing the stamping upper die 230. Each threaded hole 205 communicates with a corresponding insertion hole 204. A first insertion block 231 and two second insertion blocks 232 are provided on the side of the stamping upper die 230 near the upper die receiving platform 220. The second insertion block 232 has a through hole 206, and the two side walls of the first insertion block 231 have two symmetrical limiting slots 207. The first insertion block 231 is adapted to the first insertion slot 202 and is inserted into the first insertion slot 202. The second insertion block 232 is adapted to the second insertion slot 203 and is inserted into the second insertion slot 203.

[0028] Two fixing components 240 are symmetrically arranged on both sides of the upper mold receiving platform 220. Each fixing component 240 includes a fixing handle 241, a fixing rod 242, and a first fixing bolt 243. The fixing handle 241 is connected to one end of the fixing rod 242. In this embodiment, the fixing handle 241 is a circular plate-shaped structure. Furthermore, the fixing handle 241 and the fixing rod 242 are integrally formed. The insertion hole 204, the through hole 206, and the limiting slot 207 are all adapted to the fixing rod 242. In this embodiment, the fixing rod 242 is a quadrangular prism structure. The fixing rod 242 passes sequentially through the insertion hole 204, the through hole 206, and the limiting slot 207. The fixed insertion rod 242 is provided with a fixing screw hole 208. Both the threaded hole 205 and the fixing screw hole 208 are adapted to the first fixing bolt 243. The first fixing bolt 243 passes through the threaded hole 205 and the fixing screw hole 208 in sequence to connect the fixed insertion rod 242 to the upper mold receiving platform 220.

[0029] When the upper stamping die 230 needs to be installed, the first insertion block 231 is inserted into the first insertion slot 202, and the second insertion block 232 is inserted into the second insertion slot 203. The fixing rod 242 is passed through the insertion hole 204, the through hole 206, and the limiting slot 207 in sequence. The first fixing bolt 243 is passed through the threaded hole 205 and the fixing screw hole 208 in sequence to connect the fixing rod 242 to the upper die receiving platform 220. In this way, the two fixing components 240 facilitate the installation and removal of the upper stamping die 230.

[0030] To adjust the position of the upper stamping die 230, in one embodiment, a frustum-shaped base 233 is provided at one end of the upper stamping die 230 near the upper die receiving platform 220. Receiving grooves 209 are provided on both sides of the upper die receiving platform 220 near the frustum-shaped base 233, and a rotating screw hole 401 is provided in the middle area of ​​the bottom of the receiving groove 209. Two adjusting components 250 are symmetrically arranged on both sides of the frustum-shaped base 233. Each adjusting component 250 includes a drive head 251 and a rotating screw 252. The drive head 251 has a frustum-shaped structure, and its tip is connected to the rotating screw 252. In this embodiment, the drive head 251 and the rotating screw 252 are integrally formed. The outer wall of the drive head 251 slides against the outer wall of the frustum-shaped base 233. The rotating screw hole 401 is adapted to the rotating screw 252, which is inserted into the rotating screw hole 401 and screwed to the upper die receiving platform 220. In this embodiment, a driving groove (not shown) is provided at the end of the driving head 251 away from the rotating screw 252. Further, the driving groove is a cross-shaped groove. The driving head 251 can be driven to rotate through the driving groove. The driving head 251 drives the rotating screw 252 to rotate, and the rotating screw 252 moves along the rotating screw hole 401 during rotation, causing the driving head 251 to move closer to the rotating screw hole 401. The outer wall of the driving head 251 slides against the outer wall of the frustum-shaped base 233 to adjust the position of the stamping upper die 230 through the frustum-shaped base 233. In this way, the two adjusting components 250 can adjust the front and rear positions of the stamping upper die 230 to calibrate the positions of the stamping upper die 230 and the lower die mechanism 300, increasing the working stability of the composite hardware mold 10.

[0031] To increase the working stability of the composite hardware mold 10, the lower mold mechanism 300 includes a lower mold support platform 310, a stamping lower mold 320, and several second fixing bolts 330. The lower mold support platform 310 is mounted on the support platform 110, and a connecting plate 321 is provided at the bottom of the stamping lower mold 320. The connecting plate 321 is connected to the lower mold support platform 310 by the second fixing bolts 330. This facilitates the installation and disassembly of the stamping lower mold 320 and increases the working stability of the composite hardware mold 10.

[0032] To facilitate material unloading, the lower die mechanism 300 also includes several unloading components 340. The bottom of the lower die cavity 301 of the stamping lower die 320 has several elastic grooves 302, and each unloading component 340 is correspondingly disposed within one elastic groove 302. Each unloading component 340 includes a drive column 341 and a first compression spring 342. The drive column 341 is adapted to the elastic groove 302, inserted into the elastic groove 302, and slidably connected to the stamping lower die 320. One end of the drive column 341 inserted into the elastic groove 302 is elastically connected to the bottom of the elastic groove 302 via the first compression spring 342. During stamping, the drive column 341 is compressed and retracts into the elastic groove 302, compressing the first compression spring 342 within the elastic groove 302. After stamping, the first compression spring 342 recovers its elastic deformation and ejects the stamped product through the drive column 341, facilitating unloading. Thus, each elastic groove 302 facilitates unloading.

[0033] To avoid direct, rigid contact between the upper stamping die 230 and the lower stamping die 320, a receiving groove 101 is provided on the support platform 110. Several buffer grooves 102 are evenly distributed at the bottom of the receiving groove 101, and a sliding groove 103 is provided in the middle area of ​​the bottom of the buffer groove 102. The receiving groove 101 is adapted to the lower die receiving platform 310, which is inserted into the receiving groove 101 and slidably connected to the support platform 110. Several buffer components 350 are provided at the bottom of the lower die receiving platform 310. Each buffer component 350 includes a second compression spring 351 and a sliding post 352. The second compression spring 351 is sleeved on the sliding post 352. The sliding post 352 is adapted to the sliding groove 103, inserted into the sliding groove 103, and slidably connected to the support platform 110. During the stamping process, each of the second compression springs 351 buffers the impact force applied by the upper stamping die 230 to the lower stamping die 320, preventing direct hard contact between the upper and lower stamping dies, thereby avoiding mutual wear between them. After compression, all the second compression springs 351 are housed within the buffer groove 102. Thus, each buffer assembly 350 prevents direct hard contact between the upper and lower stamping dies 230, avoiding mutual wear between them. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
