[0002] Brake shoes are critical components in automotive braking systems. Their design and manufacturing processes are essential for ensuring vehicle safety and performance. Manufactured through stamping and welding processes, they are typically made of metal and have a specific shape and structure. During the manufacturing process, the stamping and welding steps can cause deformation of the brake shoes. If these deformations are not corrected, they will affect the dimensional accuracy and shape consistency of the brake shoes, thus impacting the performance of the braking system. Therefore, it is necessary to perform shaping processing on the brake shoes to ensure their subsequent performance.

[0003] The existing shaping molds still have the following problems when in use: the connection between the upper and lower molds of the existing shaping molds is relatively complicated, which makes it inconvenient to replace the molds when they are worn after long-term use, thus affecting the final performance of the shaping molds.

[0004] Therefore, it is necessary to invent a forming mold for stamping and welding shoes for automobiles to solve the above problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a forming mold for automotive stamped welded shoes, comprising a lower mold, a base fixedly connected to the bottom of the lower mold, and a motor fitted inside the base, the output shaft of the motor being driven by a threaded rod, and the threaded rod being rotatably connected to a top plate, uprights fixedly connected to the remaining three corner top walls of the base, the uprights being fixedly connected to the top plate, a movable plate being threadedly connected to the outer ring of the threaded rod, and the movable plate being movably fitted to the outer ring of the upright, a fitting groove being reserved inside the lower mold, and the stamped welded shoe body being fitted inside the fitting groove, further comprising:

[0007] The mounting assembly includes an installation port inside the movable plate, a pressure mold that engages inside the installation port, and a movable cavity inside the pressure mold. A snap-fit ​​block is slidably mounted inside the movable cavity via a threaded rod. The snap-fit ​​block engages with a snap-fit ​​groove, which is connected to the installation port, facilitating the installation of the pressure mold and the installation port.

[0008] The limiting component has an annular groove reserved inside the snap-fit ​​block, and an annular block is rotatably connected inside the annular groove. A short rod is fixedly connected to the inner wall of the annular block. The short rod is slidably connected to the limiting groove reserved inside the threaded rod II to prevent the threaded rod II from falling off the snap-fit ​​block.

[0009] Preferably, the top of the mold has a pre-reserved channel, and the channel is connected to the movable cavity, so that the rotation of the threaded rod can be actuated through the channel at the top of the mold.

[0010] Preferably, the mounting port is vertically continuous, and the inner wall of the mounting port is attached to the outer wall of the mold to achieve a vertical sliding connection, which facilitates the installation of the mold and the mounting port.

[0011] Preferably, the outer ring of the threaded rod two is provided with two sections of thread, the two sections of thread have opposite directions, and the two sections of thread are respectively threaded to the threaded grooves inside the two snap-fit ​​blocks. The two snap-fit ​​blocks that are threaded to the two sections of thread on the outer ring of the threaded rod two move towards each other or away from each other along the inner wall of the movable cavity.

[0012] Preferably, the outer wall of the snap-fit ​​block is attached to the inner wall of the movable cavity to achieve a sliding connection, and the two snap-fit ​​blocks are symmetrically arranged with reference to the central axis of the movable plate as the axis of symmetry. After the two snap-fit ​​blocks separate and move and match the snap-fit ​​groove, the mold and the movable plate are installed.

[0013] Preferably, both ends of the limiting groove are closed, and the inner wall of the limiting groove is in contact with the outer wall of the short rod to achieve a sliding connection, thereby preventing the threaded rod from falling off the snap-fit ​​block.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] 1. This utility model allows the two locking blocks to move towards each other and leave their matching locking grooves by turning the threaded rod two, making it convenient for workers to separate the mold from the movable plate. Then, turning the threaded rod two in the opposite direction causes the two locking blocks to move towards each other along the inside of the movable cavity and match and connect with the locking grooves. This allows the mold to be installed on the movable plate, making it easy to replace the mold.

[0016] 2. When the snap-fit ​​block that is threadedly connected to the threaded rod moves and the inner wall of the limiting groove abuts against the short rod, the snap-fit ​​block has no room to move, thus preventing the threaded rod from falling off the snap-fit ​​block.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-4 The forming mold for automotive stamped welded shoes shown includes a lower mold 1, a base 2 fixedly connected to the bottom of the lower mold 1, and a motor fitted inside the base 2. The output shaft of the motor is driven by a threaded rod 7, which is rotatably connected to a top plate 5. Vertical rods 6 are fixedly connected to the remaining three corner top walls of the base 2, and are fixedly connected to the top plate 5. A movable plate 4 is threadedly connected to the outer ring of the threaded rod 7, and the movable plate 4 movably fits the outer ring of the vertical rod 6. A fitting groove 11 is pre-reserved inside the lower mold 1, and a stamped welded shoe body 8 is fitted inside the fitting groove 11. The mold also includes:

[0026] The mounting component 9 has an internal mounting port 901 on the movable plate 4. The mounting port 901 is fitted with a mold 3. The mold 3 has an internal movable cavity 902. The movable cavity 902 is slidably fitted with a snap-fit ​​block 904 through a threaded rod 903. The snap-fit ​​block 904 is fitted with a snap-fit ​​groove 905. The snap-fit ​​groove 905 is connected to the mounting port 901, which facilitates the installation of the mold 3 and the mounting port 901.

[0027] The limiting component 10 has an annular groove 101 reserved inside the snap-fit ​​block 904, and an annular block 102 is rotatably connected inside the annular groove 101. A short rod 103 is fixedly connected to the inner wall of the annular block 102. The short rod 103 and the limiting groove 104 reserved inside the threaded rod 903 are slidably connected to prevent the threaded rod 903 from falling off the snap-fit ​​block 904.

[0028] The top of the mold 3 has a pre-reserved channel, which is connected to the movable cavity 902. The mounting port 901 is vertically through, and the inner wall of the mounting port 901 is attached to the outer wall of the mold 3 to achieve a sliding connection between the upper and lower parts, which facilitates the installation of the mold 3 and the mounting port 901. The outer ring of the threaded rod 903 has two threads with opposite directions, and the two threads are threaded to the threaded grooves inside the two locking blocks 904 respectively. By rotating the threaded rod 903 through the top channel of the mold 3, the two locking blocks 904 that are threaded to the two threads on the outer ring of the threaded rod 903 slide along the inner wall of the movable cavity 902. After the two locking blocks 904 move towards each other and leave the matching locking groove 905, it is convenient for the staff to separate the mold 3 from the movable plate 4.

[0029] The outer wall of the snap-fit ​​block 904 is attached to the inner wall of the movable cavity 902 to achieve a sliding connection. The two snap-fit ​​blocks 904 are symmetrically arranged with reference to the central axis of the movable plate 4. After the two snap-fit ​​blocks 904 separate and move and match the snap-fit ​​groove 905, the pressure mold 3 and the movable plate 4 are installed. Both ends of the limiting groove 104 are closed. The inner wall of the limiting groove 104 is attached to the outer wall of the short rod 103 to achieve a sliding connection. When the snap-fit ​​block 904, which is threadedly connected to the threaded rod 903, moves and the inner wall of the limiting groove 104 abuts against the short rod 103, the snap-fit ​​block 904 has no room to move, thus preventing the threaded rod 903 from falling off the snap-fit ​​block 904.

[0030] Working principle: When using a forming mold for automotive stamped welded shoes, the motor is first started to drive the rotation of the threaded rod 7 connected to the motor output shaft. This causes the movable plate 4, which is threadedly connected to the threaded rod 7, to move up and down under the limiting action of the three uprights 6. This, in turn, causes the pressure mold 3, which is snapped into place inside the movable plate 4, to descend and shape the stamped welded shoe body 8, which is snapped into place inside the fitting groove 11 of the lower mold 1. Subsequently, the motor is started in reverse to rotate the threaded rod 7, causing the pressure mold 3 to rise, making it easier to remove the shaped stamped welded shoe body 8.

[0031] The two locking blocks 904, which are threadedly connected to the two sections of the outer ring of the threaded rod 903, slide along the inner wall of the movable cavity 902. After the two locking blocks 904 move towards each other and leave or come close to the interior of the matching locking groove 905, it is convenient for the staff to separate and install the pressure mold 3 and the movable plate 4.

[0032] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
