A car is a non-rail-borne vehicle with four or more wheels driven by power. It is a tool manufactured by people to transport people and goods. A car consists of many systems, including engine system, transmission system, running system, steering system, suspension system and braking system. An important component of the braking system is the brake pad. Currently, the hot pressing process of brake pads mostly uses a four-column one-time forming hot press. The hot pressing mold is directly fixed to the hot press by bolts. Therefore, it is necessary to design a heat insulation device for the brake pad mold.
[0003] The existing mold cavity is directly connected to the equipment without a heat insulation device. During the hot pressing process, the mold needs to be heated to 140-170℃, which causes some heat to be directly conducted to the equipment body through the mold. This not only causes heat loss, but also leads to excessively high internal temperature of the hot press body, which will accelerate the aging efficiency of the internal circuits of the hot press body, affect its service life, and increase the maintenance cost of the hot press body.

By reducing heat conduction during hot pressing, the high temperature phenomenon inside the hot press body is reduced, thereby extending the service life of the hydraulic press body.
[0005] To achieve the above objectives, a brake pad mold heat insulation device is provided, comprising a storage chamber, a rectangular cooling plate placed at the center of the storage chamber, a semiconductor cooling chip extending to the outside of the storage chamber installed at the bottom of the rectangular cooling plate, an isolation groove installed at the center of the top of the storage chamber, a heat-conducting groove plate installed inside the isolation groove, a concave mold installed inside the heat-conducting groove plate, a convex mold mating with the inner top of the concave mold, and a liquid flow component provided on one side of the storage chamber.
[0006] According to the aforementioned brake pad mold heat insulation device, the liquid flow assembly includes a second connecting pipe, a water pump, a first connecting pipe, and a drain pipe. The drain pipe is installed at the top of one side of the isolation groove, and the bottom of the isolation groove is connected to the top of one side of the storage chamber. The water pump is installed on the side of the storage chamber away from the drain pipe. The input end of the water pump is provided with a second connecting pipe, and the second connecting pipe is connected to one side of the bottom of the storage chamber. The output end of the water pump is provided with a first connecting pipe, and the first connecting pipe is connected to the top of the other side of the isolation groove.
[0007] According to the aforementioned brake pad mold heat insulation device, the inner side of the isolation groove is provided with a cavity, and the cavity is connected to the interior of the connecting pipe and the drain pipe.
[0008] According to the aforementioned brake pad mold heat insulation device, a base plate is provided at the middle position of the bottom of the storage compartment, and a through groove that cooperates with the semiconductor cooling chip is opened at the middle position inside the base plate. Internal threaded fixing plates are installed on both sides of the base plate, and bolts are threadedly connected to the two ends of the two sets of internal threaded fixing plates on opposite sides.
[0009] According to the aforementioned brake pad mold heat insulation device, a liquid inlet is provided on one side of the top of one end of the front of the storage compartment, and a sealing cap that matches the liquid inlet is closed inside the liquid inlet.
[0010] According to the aforementioned brake pad mold heat insulation device, the semiconductor cooling chip is formed by connecting N-type semiconductors and P-type semiconductors in series, and both the N-type semiconductors and P-type semiconductors are connected to the power supply via external connecting lines.

[0012] According to the aforementioned brake pad mold heat insulation device, the bottom of the storage compartment has openings on both sides, and the openings are sealed to the semiconductor cooling chip.
[0013] Compared with the prior art, the beneficial effects of this utility model are: the material of the heat-conducting groove plate can easily absorb excess heat inside the concave mold, and the surrounding structure design of the heat-conducting groove plate can ensure the uniformity of heating inside the concave mold in the later stage. At the same time, the isolation groove and storage chamber designed on the outside of the heat-conducting groove plate can block the heat inside, effectively preventing heat from being conducted to the hot press body during hot pressing, alleviating the high temperature phenomenon caused by heat conduction in the hot press body, and thus reducing the impact of high temperature phenomenon on the service life of the hot press body.
[0014] Meanwhile, the structural design of the semiconductor cooling chip and rectangular heat-conducting sleeve can easily achieve the cooling function of the liquid inside the storage chamber. Furthermore, through the structural design of the water pump, connecting pipe 2 and connecting pipe 1, the cooling liquid inside the storage chamber can be drawn into the interior of the isolation groove.

The output end of the water pump 9 is provided with a first connecting pipe 8, and the first connecting pipe 8 is connected to the top of the other side of the isolation groove 3. Through the operation of the water pump 9, the liquid inside the storage chamber 1 can be drawn into the interior of the isolation groove 3 through the second connecting pipe 10 and the first connecting pipe 8, and finally discharged into the interior of the storage chamber 1 through the drain pipe 2, thus repeating the cycle.
[0025] A cavity is provided inside the isolation groove 3, and the cavity is connected to the interior of the connecting pipe 8 and the drain pipe 2. The cavity facilitates the entry and flow of liquid to achieve the cooling and heat insulation function. A base plate is provided at the middle of the bottom of the storage chamber 1, and a through groove is provided in the middle of the bottom of the base plate to cooperate with the semiconductor cooling chip 11. Internal threaded fixing plates are installed on both sides of the base plate, and bolts are threaded to the ends of the two sets of internal threaded fixing plates on opposite sides. The base plate design provides support for the placement of the storage chamber 1 and the above components, and the through groove facilitates the heat dissipation function of the semiconductor cooling chip 11.

The punch 5 is connected to the drive component on the top of the hot press body. Then, through the design and cooperation of the concave die 6 and the punch 5, the hot pressing of the brake pads can be achieved.
[0027] During hot pressing, excess heat inside the concave mold 6 can be absorbed by the rectangular cooling sleeve 7. The surrounding design of the rectangular cooling sleeve 7 can achieve uniform heating inside the concave mold 6, ensuring the quality of the brake pad hot pressing later. The surrounding design of the isolation groove 3 can block the heat inside the rectangular cooling sleeve 7.

The liquid can absorb the heat inside the rectangular heat-conducting sleeve 7 to improve the heat isolation quality in the later stage. At the same time, it can also improve the cooling efficiency of the mold inside the concave mold 6 in the later stage. Finally, the liquid inside the drain pipe 2 can carry the heat and be discharged into the interior of the storage chamber 1 through the drain pipe 2. This cycle is repeated. Through the structural design of the semiconductor cooling chip 11 and the rectangular heat-conducting sleeve 7, the liquid inside the storage chamber 1 can be cooled, achieving the cooling effect in the later stage. Furthermore, through the structure and material of the rectangular heat-conducting sleeve 7, the contact area with the liquid can be increased, improving the cooling efficiency of the liquid inside the storage chamber 1 in the later stage.
