Abstract
Description
Technical Field
[0001] This utility model belongs to the field of brake pad mold technology, specifically a cleaning device for brake pad pressing and forming molds. Background Technology
[0002] Brake pads are a key component of a car's braking system. They convert the vehicle's kinetic energy into heat energy through friction with the brake disc (or brake drum), thereby achieving deceleration or stopping. Their performance directly affects driving safety and must have a high coefficient of friction, high temperature resistance, wear resistance, and stability.
[0003] Brake pads are formed by pressing them into a mold. Friction material is placed into the mold cavity and pressed under high pressure to form a pad structure that meets design standards. However, impurities, hardened material debris, or oxide layers remaining inside the mold can become embedded in the brake pad matrix during subsequent pressing processes, leading to quality defects such as unstable friction coefficient, surface cracks, and even braking noise. Therefore, thorough cleaning of the mold is a key process to ensure the consistency, durability, and braking performance of brake pads. Existing molds require operators to clean them with tools after use. This method is not only very troublesome, but also poses certain safety hazards to operators when cleaning, as the mold is usually fixed to the equipment. Therefore, improvements are needed.

[0007] As a preferred embodiment of this utility model, there are four push blocks, and each of the four push blocks has a lifting plate fixedly installed at its bottom.
[0008] As a preferred embodiment of this utility model, the four corners of the lifting plate are all movably fitted with limit rods, the top of the limit rods are fixedly connected to the bottom of the top plate, and the bottom of the limit rods are fixedly connected to the bottom of the inner surface of the worktable.
[0009] As a preferred embodiment of this utility model, a power motor is fixedly installed on the right side of the workbench, and a double threaded rod is fixedly connected to the other end of the output shaft of the power motor. The left end of the double threaded rod extends into the interior of the workbench and is movably sleeved with the inner wall of the workbench.

Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] like Figures 1 to 5 As shown, this utility model provides a cleaning device for brake pad pressing and forming molds, including a workbench 1, a top plate 2 fixedly installed on the top of the workbench 1, a push block 3 movably sleeved inside the top plate 2, a lower mold 4 fixedly sleeved on the top of the top plate 2, slide rails 5 fixedly installed on both the front and rear sides of the top of the top of the top plate 2, a slider 6 movably sleeved on the left side of the outer surface of the slide rail 5, the bottom of the slider 6 movably connected to the top of the top plate 2, there are two sliders 6, a baffle 7 fixedly installed on the top of each slider 6, a scraper 8 fixedly connected between the baffles 7, a round block 9 fixedly installed on the top of the baffles 7, a drive motor 10 fixedly connected to the front end of the top plate 2, a rotating shaft 11 fixedly connected to the other end of the output shaft of the drive motor 10, a rotating rod 12 fixedly sleeved on the outer surface of the rotating shaft 11, and the inner surface of the rotating rod 12 movably sleeved with the outer surface of the round block 9.
[0023] By setting the push block 3, it can be inserted into the interior of the lower mold 4 when it rises, thereby pushing the impurities on the inner surface of the lower mold 4 upward. When the top of the push block 3 rises to the same height as the top of the lower mold 4, the drive motor 10 is started, causing the rotating shaft 11 to drive the rotating rod 12 to rotate. The rotating rod 12 squeezes and pushes the outer surface of the round block 9, thereby driving the scraper 8 to move to the right under the limiting action of the slide rail 5 and the slider 6, so that the scraper 8 scrapes away and cleans the impurities on the top of the lower mold 4 and the push block 3.
[0024] Among them, a support plate 13 is fixedly installed on the rear side of the top of the top plate 2, and a pneumatic cylinder 14 is fixedly connected to the top of the support plate 13. The bottom end of the pneumatic cylinder 14 passes through the support plate 13 and extends to the bottom of the support plate 13 and is movably sleeved with the inner wall of the support plate 13. The bottom end of the pneumatic cylinder 14 is fixedly connected to the upper mold 15.
[0025] The operator activates the pneumatic cylinder 14, which causes the upper mold 15 to move downwards. The upper mold 15 is inserted into the lower mold 4, thereby pressing the brake pads.
[0026] There are four push blocks 3, and each of the four push blocks 3 has a lifting plate 16 fixedly installed at its bottom.
[0027] When the lifting plate 16 moves upward, it will drive the four lifting plates 16 to move upward.
[0028] Among them, the four corners of the lifting plate 16 are movably sleeved with limit rods 17. The top of the limit rod 17 is fixedly connected to the bottom of the top plate 2, and the bottom of the limit rod 17 is fixedly connected to the bottom of the inner surface of the worktable 1.
[0029] By setting the limit rod 17, the limit rod 17 can limit and guide the lifting plate 16, making the lifting plate 16 more stable when rising and falling.
[0030] A power motor 18 is fixedly installed on the right side of the workbench 1. A double threaded rod 19 is fixedly connected to the other end of the output shaft of the power motor 18. The left end of the double threaded rod 19 extends into the interior of the workbench 1 and is movably sleeved with the inner wall of the workbench 1.
[0031] The operator starts the power motor 18, which causes the double threaded rod 19 to rotate. The threads on the left and right sides of the outer surface of the double threaded rod 19 are in opposite directions.
[0032] Among them, the left and right sides of the outer surface of the double threaded rod 19 are threaded with movable plates 20. There are two movable plates 20, and the bottom of the two movable plates 20 are movably connected to the bottom of the inner surface of the worktable 1.
[0033] When the double threaded rod 19 rotates, it will cause the two moving plates 20 to move in opposite directions.
[0034] The front and rear ends of the movable plate 20 are both hinged with hinge rods 21, and the top of the hinge rods 21 is hinged to the bottom of the lifting plate 16.
[0035] When the two moving plates 20 move toward each other, they will drive the hinge rod 21 to move, causing the hinge rod 21 to push the lifting plate 16 to rise under the limiting action of the limiting rod 17.
[0036] Working principle and usage process of this utility model:
[0037] The operator puts the material into the lower mold 4, and then starts the pneumatic cylinder 14, which drives the upper mold 15 to move downward to press the brake pad. Then the operator starts the power motor 18, which drives the double threaded rod 19 to move the two moving plates 20 in opposite directions. This allows the lifting plate 16 to move upward under the limiting action of the limiting rod 17 through the hinge rod 21, which in turn causes the push block 3 to move upward. This push block 3 then pushes the brake pad pressed inside the lower mold 4 upward, making it easier for the operator to demold the brake pad.
[0038] When the lower mold 4 needs to be cleaned, the operator starts the power motor 18, causing the push block 3 to rise. The push block 3 will push the impurities on the inner surface of the lower mold 4 to rise until the top of the push block 3 rises to the same height as the top of the lower mold 4. At this time, the drive motor 10 is started, causing the rotating shaft 11 to drive the rotating rod 12 to rotate. The rotating rod 12 will squeeze the outer surface of the push block 9, thereby causing the slider 6, baffle 7, and scraper 8 to move to the right under the limiting action of the slide rail 5. The scraper 8 will push the impurities on the top of the lower mold 4 and the top of the push block 3 to the right and onto the top of the top plate 2. At the same time, due to the design of the baffle 7, the baffle 7 can block the impurities and prevent them from falling from the side of the lower mold 4, thereby achieving the purpose of cleaning the lower mold 4.
