Detailed Implementation
[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0025] This application discloses a quick-change device for terminal crimping molds.
[0026] Reference Figure 1-4 A quick-change device for terminal crimping molds includes a workbench 101. A mounting base 102 is slidably mounted on the top of the workbench 101. The mounting base 102 has two placement positions for placing the terminal crimping mold 103. The top of the mounting base 102 has multiple positioning grooves 401. The bottom of the terminal crimping mold 103 is fixedly mounted with a positioning seat 402, and the positioning seat 402 is adapted to the corresponding positioning groove 401. A fixing groove 501 is opened on the side of each of the two corresponding positioning seats 402 that are close to each other. A moving groove 502 is opened on the side of each of the two corresponding positioning grooves 401 that are close to each other. A fixing pin 503 is slidably mounted in the moving groove 502, and the fixing pin 503 is adapted to the corresponding fixing groove 501. A return spring 504 is fixedly mounted on one side of the fixing pin 503, and one end of the return spring 504 is fixedly mounted on the inner wall of the moving groove 502.
[0027] In this embodiment, a drive hole 602 is provided on the bottom inner wall of the moving groove 502. A drive rod 603 is slidably installed in the drive hole 602, and the top end of the drive rod 603 is fixedly installed on the fixing pin 503. Two rectangular holes 601 with open tops are provided on the front side of the worktable 101, and the bottom end of the drive rod 603 extends into the rectangular holes 601. A trapezoidal extrusion seat 604 for extrusion by the drive rod 603 is fixedly installed on the bottom inner wall of the rectangular holes 601. This structural design allows the fixing pin 503 to move automatically with the help of the trapezoidal extrusion seat 604 when the mounting base 102 moves, without the need for additional manual operation to fix or release the fixing mold, thus improving the degree of automation of the operation.
[0028] In this embodiment, the top of the workbench 101 has two T-shaped slots 201, and the bottom of the mounting base 102 has two T-shaped seats 202 fixedly installed, with the T-shaped seats 202 slidably connected to the corresponding T-shaped slots 201. The cooperation between the T-shaped slots 201 and the T-shaped seats 202 can effectively limit the vertical displacement of the mounting base 102, ensuring that the mounting base 102 remains stable during sliding and avoiding shaking.
[0029] In this embodiment, a guide groove 301 is provided on the top of the worktable 101. A movable seat 303 is slidably installed in the guide groove 301, and the top of the movable seat 303 is fixedly installed on the mounting base 102. The same threaded rod 302 is rotatably installed on the front and rear inner walls of the guide groove 301, and the movable seat 303 is threaded onto the threaded rod 302. A servo motor 304 is installed on the rear side of the worktable 101, and the output shaft of the servo motor 304 is fixedly connected to the threaded rod 302. By driving the threaded rod 302 to rotate through the servo motor 304, the movable seat 303 and the mounting base 102 can be moved precisely, which can accurately control the switching position of the mold and ensure that the new mold can accurately reach the working position.
[0030] In this embodiment, a controller is installed on one side of the workbench 101, and the servo motor 304 is electrically connected to the controller. The controller makes it convenient for operators to control the servo motor 304, realize convenient operation of mold changing process, and further improve work efficiency.
[0031] The working principle of this utility model is as follows: When changing the mold, the terminal crimping mold 103 to be replaced is first placed in an idle position on the mounting base 102, so that the positioning seat 402 at the bottom of the terminal crimping mold 103 to be replaced is inserted into the corresponding positioning groove 401. At this time, the servo motor 304 is started by the controller. The servo motor 304 drives the threaded rod 302 to rotate. The threaded rod 302 drives the moving seat 303 to slide in the guide groove 301, thereby driving the mounting base 102 to slide on the worktable 101. During the movement of the mounting base 102, the T-shaped seat 202 at the bottom of the mounting base 102 slides in the T-shaped groove 201, which plays a stabilizing and guiding role in the movement of the mounting base 102.
[0032] When the mounting base 102 moves, causing the station where the terminal crimping mold 103 to be replaced is located to move to the working position, the bottom end of the drive rod 603 corresponding to the terminal crimping mold 103 will contact the trapezoidal extrusion seat 604 in the rectangular hole 601. As the mounting base 102 continues to move, the trapezoidal extrusion seat 604 extrudes the drive rod 603, and the drive rod 603 slides upward and drives the fixing pin 503 to slide in the moving groove 502. The return spring 504 is compressed. When the terminal crimping mold 103 to be replaced reaches the working position, the fixing pin 503 is inserted into the fixing groove 501 on the new mold positioning base 402 under the action of the return spring 504, so that the terminal crimping mold 103 to be replaced is fixed in the working position.
[0033] At the same time, as the mounting base 102 moves away from the working position of the replacement lower terminal crimping mold 103, the bottom end of the drive rod 603 corresponding to the replacement lower terminal crimping mold 103 gradually gets away from the pressure of the trapezoidal extrusion seat 604. Under the action of the return spring 504, the fixing pin 503 is pulled out from the fixing groove 501 of the old mold positioning seat 402, releasing the fixation of the old mold.
[0034] In this way, the new mold is moved to the working position and fixed, while the old mold leaves the working position and is released from its fixed position, thus achieving the goal of quick mold replacement.
[0035] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
