Description

Technical Field

[0001] This utility model relates to the field of brake pad technology, specifically to a brake pad hot pressing molding machine. Background Technology

[0002] In my country, electric bicycles have become a major mode of transportation in cities, and their ownership is increasing year by year. Due to their convenience, they are favored by a large number of consumers. Among them, the safe operation of electric bicycles is particularly important. The brake is the most important safety component of electric bicycles. Improving the braking performance of electric bicycles is fundamental to ensuring their safe operation. The role of the braking performance of electric bicycles in traffic safety is undeniable.

[0003] A search revealed that CN221456883U discloses a brake pad hot pressing forming device, comprising a base shell, support plates connected to both sides of the top surface of the base shell, a top plate connected to the top of the support plates, a hydraulic cylinder on the top surface of the top plate, a piston end of the hydraulic cylinder passing through the top plate and connected to a lifting plate, an upper mold on the bottom surface of the lifting plate, a heating plate connected to the bottom surface of the upper mold, a lower mold on the top surface of the base shell, and a stripping template attached to the inner wall of the lower mold. A motor drives a gear to rotate, thereby moving a rack and ejector rod upwards, thus causing the stripping plate to be ejected. The template moves upward, facilitating the demolding of the brake pads without requiring manual removal from the lower mold. A guide support structure ensures stable movement of the rack. However, the existing hot-press molding die struggles to cool the hot-pressed brake pads, relying solely on two cooling fans, which reduces the machine's production efficiency. Therefore, improving the existing hot-press molding machine and designing a new brake pad hot-press molding machine to address these technical shortcomings and enhance the overall practicality of the machine is crucial.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A brake pad hot pressing molding machine includes a hot press body, a connecting frame fixedly connected to the top of the hot press body, heat dissipation components provided at both ends of the connecting frame, an upper mold slidably connected inside the connecting frame, a heating plate fixedly connected to the bottom of the upper mold, a lower mold fixedly connected to the top of the hot press body and below the heating plate, and a lifting component provided inside the hot press body and inside the lower mold.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. In this utility model, through the design of the heat dissipation component, the heat dissipation component mainly works by combining coolant circulation and fan-guided heat dissipation. The component has a circulation pipe inside, which is filled with coolant and works with a circulation pump to achieve coolant circulation. At the same time, a semiconductor refrigeration chip is installed on the outside of the receiving cylinder to cool the flowing coolant. The heat sink is used to dissipate heat from the heating end of the semiconductor refrigeration chip to prevent it from affecting the cooling effect. In addition, the conduction plate is in close contact with the circulation pipe to reduce the surface temperature of the conduction plate through heat conduction. The guide fan introduces low-temperature gas into the connecting frame to dissipate heat from the brake pads. The design of the heat dissipation component improves the overall practicality of the hot press molding machine, making it more efficient and stable in the production process.

[0017] 2. In this utility model, through the design of the lifting assembly, the lifting assembly mainly uses a drive motor to drive the drive screw to rotate, thereby realizing the displacement of the moving frame and thus driving the lifting plate to rise and fall. The fixed shell is equipped with a drive screw and a moving frame, which are fixedly connected to the lifting plate. When the drive screw rotates, the moving frame moves along the screw direction, thereby driving the lifting plate to rise and fall. The lifting assembly can quickly and accurately realize the lifting operation of the brake pads, reducing the tediousness and time consumption of manual operation and improving production efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figures 1-5 This utility model provides a technical solution:

[0027] A brake pad hot pressing molding machine includes a hot press body 1, a connecting frame 2 fixedly connected to the top of the hot press body 1, heat dissipation components 3 provided at both ends of the connecting frame 2, an upper mold 4 slidably connected inside the connecting frame 2, an electric heating plate 5 fixedly connected to the bottom of the upper mold 4, a lower mold 6 fixedly connected to the top of the hot press body 1 and below the electric heating plate 5, and a lifting component 7 provided inside the hot press body 1 and inside the lower mold 6.

[0028] The heat dissipation assembly 3 is used to dissipate heat from the brake pads. The heat dissipation assembly 3 includes a connecting shell 8 fixedly connected to the outside of the connecting frame 2. A conduction plate 9 is fixedly connected inside the connecting shell 8. A circulation pipe 10 is fixedly connected to the outside of the conduction plate 9. Two sets of guide fans 11 are fixedly connected to the end of the connecting shell 8 away from the connecting frame 2.

[0029] The lifting assembly 7 is used to eject the brake pads.

[0030] Furthermore, a receiving cylinder 12 is fixedly connected to the outside of the circulation pipe 10. A circulation pump 13 is fixedly connected to the end of the receiving cylinder 12 away from the circulation pipe 10. The end of the circulation pump 13 away from the receiving cylinder 12 is fixedly connected to the circulation pipe 10. The inside of the circulation pipe 10 is filled with coolant. When the circulation pump 13 is started, it works with the receiving cylinder 12 to allow the coolant inside the circulation pipe 10 to flow.

[0031] A semiconductor cooling chip 14 is fixedly connected to the outside of the receiving cylinder 12, and a heat sink 15 is fixedly connected to the outside of the connecting shell 8 and located outside the semiconductor cooling chip 14. When the coolant flows into the inside of the receiving cylinder 12, the semiconductor cooling chip 14 is activated, and the coolant can be cooled through the cooling end. The heat sink 15 dissipates heat from the heating end, preventing the heating end from affecting the operation of the cooling end.

[0032] Secondly, the conductive plate 9 has a through groove 16 inside, and the connecting shell 8 has multiple sets of guide grooves 17 at one end near the connecting frame 2. When the guide fan 11 is activated, the gas is introduced into the interior of the connecting shell 8, so that the gas can contact the circulation pipe 10 and the conductive plate 9. The low-temperature coolant contacts the circulation pipe 10, so that the circulation pipe 10 can be cooled. The surface of the circulation pipe 10 emits low-temperature gas, which contacts the conductive plate 9, so that the surface temperature of the conductive plate 9 is reduced. When the gas contacts the circulation pipe 10 and the conductive plate 9, the temperature is reduced. Through the through groove 16 and the guide groove 17, the gas can be introduced into the interior of the connecting frame 2, reducing the temperature inside the connecting frame 2, so that the brake pads can be cooled.

[0033] Furthermore, the lifting assembly 7 includes a lifting plate 18 slidably connected to the interior of the lower mold 6. The bottom of the lifting plate 18 is provided with a fixed shell 19. A movable frame 20 is slidably connected inside the fixed shell 19. The movable frame 20 is fixedly connected to the lifting plate 18. The fixed shell 19 is fixedly connected to the main body 1 of the hot press. A drive screw 21 is rotatably connected inside the fixed shell 19 and inside the movable frame 20. The movable frame 20 and the drive screw 21 are threadedly connected. The bottom of the drive screw 21 is fixedly connected to the drive end of the drive motor 22. When the drive motor 22 is started, it drives the drive screw 21 to rotate, so that the movable frame 20 can be displaced, which in turn drives the lifting plate 18 to be displaced, so that the lifting plate 18 can drive the brake pad to be displaced, lifting the brake pad out from the interior of the lower mold 6 for easy removal of the brake pad.

[0034] Furthermore, a telescopic cylinder 23 is fixedly connected to the top of the connecting frame 2. The driving end of the telescopic cylinder 23 is fixedly connected to the upper mold 4. When the telescopic cylinder 23 is activated, it drives the upper mold 4 to move, so that the heating plate 5 can move and move into the interior of the lower mold 6, so that the brake pad can be hot-pressed.

[0035] In this embodiment, the specific implementation scenario is as follows: In actual use, the telescopic cylinder 23 is activated to move the upper mold 4, allowing the heating plate 5 to move into the lower mold 6, enabling the brake pad to be hot-pressed. After the brake pad is formed, the circulation pump 13 is activated in conjunction with the receiving cylinder 12 to allow the coolant inside the circulation pipe 10 to flow. The semiconductor cooling chip 14 is activated to cool the coolant through the cooling end, and the heat sink 15 dissipates heat from the heating end to prevent the heating end from affecting the operation of the cooling end. The guide fan 11 is activated to introduce gas into the connecting shell 8, allowing the gas to contact the circulation pipe 10 and the conduction plate 9. The low-temperature coolant contacts the circulation pipe 10, enabling the circulation pipe 10 to be hot-pressed. The circulating pipe 10 emits low-temperature gas, which comes into contact with the conduction plate 9, thus lowering the surface temperature of the conduction plate 9. The gas, in contact with the circulating pipe 10 and the conduction plate 9, helps to reduce the temperature. Through the through groove 16 and guide groove 17, the gas is guided into the interior of the connecting frame 2, reducing the internal temperature of the connecting frame 2 and thus dissipating heat from the brake pads. The drive motor 22 is started, driving the drive screw 21 to rotate, causing the moving frame 20 to shift, which in turn causes the lifting plate 18 to shift, allowing the brake pads to be lifted out of the lower mold 6 for easy removal. Compared with existing hot press molding machines, this invention improves the overall practicality of the hot press molding machine through its design.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
