Description

Technical Field

[0001] This utility model relates to the field of hot pressing mold technology, specifically a hot pressing mold for producing brake pads. Background Technology

[0002] In the brake pad manufacturing process, hot pressing is a core step that determines product performance. The stability and efficiency of the hot pressing mold directly affect the molding quality and production rhythm of the brake pads. Brake pads need to be formed under high temperature and high pressure through the forming groove of the hot pressing mold, requiring precise mold positioning. However, most hot pressing molds currently used for brake pad production are single-stage mold designs, requiring a shutdown for material removal after hot pressing, which makes continuous production impossible. Therefore, we propose a new type of hot pressing mold for brake pad production. Utility Model Content

[0003] The purpose of this utility model is to provide a hot pressing mold for producing brake pads, which has the advantage of continuous production and solves the problem that most hot pressing molds used for producing brake pads are single-stage molds, which require stopping the machine to remove materials after hot pressing and cannot produce continuously.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a hot pressing mold for producing brake pads, comprising a base plate, a worktable fixedly connected to the top of the base plate via a bracket, a first groove formed on the top of the worktable, a threaded rod rotatably connected to the inner cavity of the first groove via a bearing, a threaded sleeve threadedly connected to the outer surface of the threaded rod, an mounting platform fixedly connected to the top of the threaded sleeve, a first lower mold fixedly connected to the left end of the top of the mounting platform, a second lower mold fixedly connected to the right end of the top of the mounting platform, forming grooves formed on the top of the first and second lower molds, a top plate fixedly connected to the middle of the top of the worktable via a bracket, a first electric telescopic rod fixedly connected to the top of the top plate, a hot pressing head fixedly connected to the bottom of the first electric telescopic rod, a motor fixedly connected to the right side of the worktable, and the output shaft of the motor fixedly connected to the threaded rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. Example 1:

[0020] Please see Figure 1-3 As shown, this utility model provides a hot pressing mold for producing brake pads, including a base plate 1. A worktable 24 is fixedly connected to the top of the base plate 1 via a bracket. A first groove 6 is formed on the top of the worktable 24. A threaded rod 20 is rotatably connected to the inner cavity of the first groove 6 via a bearing. A threaded sleeve 21 is threadedly connected to the outer surface of the threaded rod 20. A mounting platform 7 is fixedly connected to the top of the threaded sleeve 21. A first lower mold 8 is fixedly connected to the left end of the top of the mounting platform 7, and a second lower mold 12 is fixedly connected to the right end of the top of the mounting platform 7. The top of the 8 and the second lower mold 12 is provided with a forming groove 15. The top plate 9 is fixedly connected to the middle of the top of the worktable 24 through a bracket. The top of the top plate 9 is fixedly connected to the first electric telescopic rod 10. The bottom of the first electric telescopic rod 10 is fixedly connected to the hot press head 11. The right side of the worktable 24 is fixedly connected to the motor 14. The output shaft of the motor 14 is fixedly connected to the threaded rod 20. The bottom of the inner cavity of the first groove 6 is a guide groove 22. The bottom of the threaded sleeve 21 is fixedly connected to the guide block 23. The guide block 23 is slidably connected to the inner cavity of the guide groove 22.

[0021] The base plate 1 of this technical solution provides stable support for the entire device. The workbench 24 is fixed to the top of the base plate 1 by a bracket to ensure structural stability during operation. The motor 14 drives the threaded rod 20 to rotate, which in turn moves the threaded sleeve 21 and the mounting platform 7 along the first groove 6. This allows the first lower mold 8 or the second lower mold 12 to be alternately sent to the bottom of the hot press head 11, realizing parallel operation of "hot pressing and material removal" and improving production continuity. The top plate 9 fixes the first electric telescopic rod 10, which pushes the hot press head 11 down to hot press the material in the forming groove 15 of the first lower mold 8 or the second lower mold 12. The guide groove 22 at the bottom of the first groove 6 slides and engages with the guide block 23 at the bottom of the threaded sleeve 21 to guide the movement of the mounting platform 7, preventing the threaded sleeve 21 from shifting when the threaded rod 20 rotates, and ensuring accurate positioning when the first lower mold 8 and the second lower mold 12 move. Example 2:

[0022] Based on Embodiment 1, this utility model is as follows: Figure 1-3 As shown, a second groove 16 is provided at the middle of the bottom of the second lower mold 12. A push plate 17 is movably connected to the inner cavity of the second groove 16. An installation groove 18 is provided at the middle of the bottom of the second groove 16. A second electric telescopic rod 19 is fixedly connected to the inner cavity of the installation groove 18. The top of the second electric telescopic rod 19 is fixedly connected to the bottom of the push plate 17. A battery box 3 is fixedly connected to the left end of the top of the base plate 1. A storage battery is fixedly connected to the inner cavity of the battery box 3. A toolbox 2 is fixedly connected to the right end of the top of the base plate 1. A partition is provided in the inner cavity of the toolbox 2. Fixing blocks 4 are fixedly connected to the front and rear ends of both sides of the base plate 1. Bolts 5 are provided on the fixing blocks 4. A PLC controller 13 is fixedly connected to the front of the workbench 24. The output end of the PLC controller 13 is electrically connected to the input end of the first electric telescopic rod 10, the motor 14, and the second electric telescopic rod 19.

[0023] In this technical solution, the second electric telescopic rod 19 is installed in the second groove 16 of the second lower mold 12 and connected to the push plate 17. After hot pressing, the push plate 17 can be pushed up to push the forming brake pad out of the forming groove 15, thereby achieving automatic demolding, avoiding product deformation caused by manual demolding, and improving material handling efficiency.

[0024] The working principle of this utility model is as follows: In use, the base plate 1 is fixed to the ground by the fixing block 4 and bolt 5, and the brake pad material is put into the forming groove 15 of the first lower mold 8 and the second lower mold 12; the PLC controller 13 starts the motor 14, drives the threaded rod 20 to rotate, and the threaded sleeve 21 drives the mounting platform 7 to move under the guidance of the guide block 23 and the guide groove 22, sending the first lower mold 8 directly below the hot press head 11; the PLC controller 13 controls the first electric telescopic rod 10 to extend, pushing the hot press head 11 to descend and hot press the material; after the hot pressing is completed, the first electric telescopic rod 10 retracts and drives the hot press head 11 to reset, the motor 14 drives the mounting platform 7 to move, and sends the second lower mold 12 to the hot pressing position. At the same time, the PLC controller 13 starts the second electric telescopic rod 19, pushes the push plate 17 to rise from the second groove 16, and pushes out the brake pad formed in the first lower mold 8; the battery box 3 ensures the operation of the equipment when the power is off, and the tool box 2 provides maintenance tools. The whole process achieves continuous production through alternating hot pressing and automatic demolding.
