Description

Technical Field

[0001] This utility model relates to the field of brake pad mold technology, and in particular to a disc brake pad forming push-pull mold. Background Technology

[0002] Disc brake pads are a key component of automotive braking systems, used to decelerate or stop vehicles. They typically consist of a friction material layer, a backing plate, etc. During operation, the brake caliper pushes the brake pads to fit tightly against the rotating brake disc, using friction to convert the vehicle's kinetic energy into heat energy, thereby achieving the braking effect. They are characterized by high braking efficiency, good heat dissipation, and uniform wear.

[0003] An investigation revealed that a Chinese utility model patent (CN209036837U) discloses a small brake pad forming mold with a reinforced structure. The mold includes an upper mold, a middle mold, a lower mold, and a reinforcing assembly. The upper mold has a flat plate structure. The middle mold has outwardly extending hook-on portions on both sides of its upper end. The lower mold includes a base plate. The reinforcing assembly includes an upper mold fixing plate, a middle mold fixing plate, and a lower mold fixing plate. The bottom surface of the upper mold fixing plate has an inwardly recessed upper mold positioning portion, within which the upper mold is detachably installed and positioned. The inner side of the middle mold fixing plate has an inwardly recessed middle mold positioning portion, which is pressed against the side wall of the middle mold. The hook-on portion hooks onto the top surface of the middle mold fixing plate. The bottom surface of the lower mold fixing plate has an inwardly recessed base plate positioning portion, within which the base plate is detachably installed and positioned. This utility model solves the problem that small brake pad forming molds cannot be installed and used on large presses, thereby saving manufacturing costs and expanding the processing range of large presses.

[0004] The aforementioned patents mostly employ fixed connection structures when used by users, lacking flexible positioning and installation designs, making it difficult to adapt to production workbenches of different specifications. This results in a long installation and positioning time, and the mold is prone to radial shaking or displacement during the user's pressing process, which in turn leads to uneven force during brake pad molding, thus affecting the accuracy and quality stability of the brake pads.

[0005] Therefore, a special push-pull mold for forming disc brake pads is needed. Utility Model Content

[0006] The purpose of this utility model is to provide a disc brake pad forming push-pull mold to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a disc brake pad forming push-pull mold, comprising a mold support body, wherein a brake disc forming mold bottom limiting shell is fixedly connected to the upper surface of the mold support body, and a forming mechanism is installed on the bottom surface of the mold support body; The forming mechanism includes a snap-fit ​​plate, which is mounted on the mold support body. A mounting plate is movably attached to the bottom surface of the snap-fit ​​plate. A stop plate is fixedly connected to the outer ring surface of the bottom limiting shell of the brake disc forming mold. A limiting rod is fixedly connected to the upper surface of the stop plate.

[0013] Preferably, a mounting flange is installed on the upper surface of the pressing mold on the brake pad, and the mounting flange is connected to the mating arm through the pressing mold on the brake pad.

[0014] Compared with the prior art, the beneficial effects of this utility model are: The forming mechanism at the bottom of the mold support body, with its movable fitting structure between the snap-fit ​​plate and the mounting plate, along with multiple mounting openings, facilitates quick and easy positioning and installation of related components. It also reduces displacement deviations during the forming process through a stable connection. The abutment plate, limit rod, and limit collar on the outer ring of the bottom limiting shell of the brake disc forming mold form a precise limiting structure. Combined with the support and adjustment of the mounting frame by the telescopic rod, this allows the pressing mold on the brake pad connected to the docking arm to move smoothly, ensuring uniform force during the pressing process. This effectively reduces brake pad forming defects caused by mold shaking or inaccurate positioning, ensuring the dimensional accuracy and structural integrity of the brake pad.

[0015] With the setting of limiting blocks, and the limiting blocks surrounding the nut as the center point, the threaded rod is stably connected to the limiting blocks through the nut. This structure not only facilitates the adjustment of the position of relevant mold components according to actual production needs, but also improves the firmness of component connections. It is suitable for the molding adjustment of brake pads of different specifications. Multiple docking arms connect to the upper pressing mold of the brake pads. With the mounting flange on the upper surface, it not only enhances the installation stability of the upper pressing mold, but also allows for the adaptation to different types of drive equipment or molding auxiliary devices through the mounting flange. The modular design of multiple components facilitates the replacement, upgrading or expansion of components according to production needs in the future, meets the production adaptation needs of diverse brake pad products, and improves the reusability and cost-effectiveness of the mold.

[0018] 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.

[0019] Please see Figure 1-4 This utility model provides a technical solution: a disc brake pad forming push-pull mold, including a mold support body 1, a brake disc forming mold bottom limiting shell 2 fixedly connected to the upper surface of the mold support body 1, and a forming mechanism 3 installed on the bottom surface of the mold support body 1; The forming mechanism 3 includes a snap-fit ​​plate 301, which is mounted on the mold support body 1. A mounting plate 302 is movably attached to the bottom surface of the snap-fit ​​plate 301. A stop plate 304 is fixedly connected to the outer ring surface of the bottom limiting shell 2 of the brake disc forming mold. A limiting rod 305 is fixedly connected to the upper surface of the stop plate 304. A limiting collar 306 is fitted to the outer ring surface of the limiting rod 305. A mounting frame 309 is fixedly connected to the upper surface of the limiting collar 306. A docking arm 310 is fixedly connected to the upper surface of the mounting frame 309. A brake pad pressing mold 311 is fixedly connected to one side of the docking arm 310. A limiting block 313 is fixedly connected to one side of the mold support body 1. A nut 314 is fixedly connected to one side of the limiting block 313. A docking plate 307 is fixedly connected to the side surface of the bottom limiting shell 2 of the brake disc forming mold.

[0020] Furthermore, the upper surface of the mounting plate 302 is provided with multiple mounting openings 303. These multiple mounting openings 303 allow for flexible docking of the mounting plate 302 with production workbenches of different specifications. This not only allows for misalignment adjustment based on the position of the screw holes on the workbench, improving the adaptability of mold installation, but also enhances the connection strength between the mounting plate 302 and the workbench through multi-point bolt fixing, preventing displacement of the mold due to vibration during molding operations and ensuring the stability of the molding reference.

[0021] Furthermore, a telescopic rod 308 is fixedly connected to the upper surface of the docking plate 307, and the telescopic rod 308 is connected to the mounting frame 309. The telescopic rod 308 can provide auxiliary support and guidance for the mounting frame 309. When the pressing mold 311 on the brake pad moves up and down, it can cooperate with the limiting structure of the limiting rod 305 and the limiting collar 306 to limit the radial sway of the mounting frame 309.

[0022] Furthermore, the nut 314 is connected to the mold support body 1 through the limiting block 313, and the limiting block 313 is arranged around the nut 314 as the center point. The surrounding limiting block 313 can provide stable support for the nut 314 from multiple directions, preventing the nut 314 from tilting or loosening when the threaded rod 315 is rotated and adjusted, thus improving the reliability of the threaded connection.

[0023] Furthermore, a threaded rod 315 is fixedly engaged on the inner ring surface of the nut 314, and the threaded rod 315 is connected to the nut 314 and the limiting block 313. The threaded engagement structure between the threaded rod 315 and the nut 314 can achieve high-precision axial displacement adjustment. The operator can finely adjust the relative position of the mold support body 1 and the pressing mold 311 on the brake pad by rotating the threaded rod 315, accurately control the forming gap, and effectively improve the dimensional accuracy of the brake pad.

[0024] Furthermore, the brake pad pressing mold 311 is connected to the mounting frame 309 via a docking arm 310, and there are multiple docking arms 310. The multiple docking arms 310 can evenly transfer the weight and pressing force of the brake pad pressing mold 311 to the mounting frame 309, avoiding excessive force on a single connection point that could damage the component.

[0025] Furthermore, an installation flange 312 is installed on the upper surface of the brake pad pressing mold 311, and the installation flange 312 is connected to the brake pad pressing mold 311 and the docking arm 310. The installation flange 312 provides a standardized connection interface, which facilitates the quick docking of the brake pad pressing mold 311 with different types of external pressing drive equipment and reduces the difficulty of equipment adaptation.

[0026] Working principle: When a user needs to use a disc brake pad forming push-pull mold, firstly, the snap-fit ​​plate 301 in the forming mechanism 3 is installed and fixed on the bottom surface of the mold bearing body 1. Then, the mounting plate 302 is movably attached to the bottom of the snap-fit ​​plate 301. Using the multiple mounting openings 303 through the mounting plate 302, the entire bottom of the mold is fixed to the production workbench by bolts and other connecting parts, thus completing the positioning of the mold base position. Check the abutment plate 304 fixed on the outer ring surface of the bottom limit shell 2 of the brake disc forming mold to confirm that the position of the limit rod 305 fixed above it is accurate. The limit collar 306 is fitted onto the outer ring surface of the limit rod 305 to ensure that the mounting frame 309 can move smoothly along the axial direction of the limit rod 305. At the same time, check the docking plate 307 fixed on the side surface of the bottom limit shell 2 of the brake disc forming mold, and confirm that the telescopic rod 308 fixed above it is firmly connected to the mounting frame 309. By adjusting the telescopic length of the telescopic rod 308, the initial height of the mounting frame 309 is initially calibrated. Through the multiple docking arms 310 fixed on the upper surface of the mounting frame 309, the brake pad pressing mold 311 is connected and fixed to the mounting frame 309. Then, using the mounting flange 312 installed on the upper surface of the brake pad pressing mold 311, it is docked with the external pressing drive equipment to ensure that the drive equipment can drive the brake pad pressing mold 311 to move synchronously. The nut 314, fixed to one side of the rotating mold support body 1 by the limiting block 313, enhances the stability of the adjustment process because the limiting block 313 is arranged around the nut 314 as the center point. The threaded rod 315, which is limited and engaged by the inner ring of the nut 314, moves axially as the nut 314 rotates. Through the contact between the end of the threaded rod 315 and mold-related components such as the mounting frame 309 or the worktable limiting structure, the relative position of the mold support body 1 and the pressing mold 311 on the brake pad is further fine-tuned to ensure molding accuracy. The brake pad raw material is then placed on the mold support body. In the designated forming area of ​​the bottom forming mechanism 3 of body 1, the external pressing drive device is started. The drive device drives the pressing mold 311 on the brake pad to move downward through the mounting flange 312. At this time, the mounting frame 309 moves smoothly down along the limit rod 305, and the telescopic rod 308 retracts synchronously. The pressing mold 311 on the brake pad presses the raw material. After the pressing is completed, the drive device drives the pressing mold 311 on the brake pad to reset upward. The telescopic rod 308 extends to assist the mounting frame 309 to return to the initial position. Finally, the formed brake pad is taken out, completing one forming process.

[0027] 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.
