Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake pad processing, and particularly relates to a hot pressing die for automobile brake pads. Background Technique

[0002] The brake pad is a very important part in the automobile braking system, and it plays a decisive role in people's safe driving. Therefore, the quality of the brake pad affects the braking effect.

[0003] In the prior art, after the brake pad manufacturing equipment presses the brake pad into shape, people need to manually dig out and remove the brake pad pressed into shape in the mold. This method is more troublesome and cumbersome, which will consume a certain amount of manpower and time. Moreover, the just-formed brake pad has residual temperature and is easy to burn people's hands, posing a safety hazard. Content of the Utility Model

[0004] The utility model provides a hot pressing die for automobile brake pads to solve the problems raised in the background technique.

[0005] To solve the above problems, the utility model provides a hot pressing die for automobile brake pads, which includes a mounting plate, a support frame, and a cavity plate. Two pneumatic telescopic rods are symmetrically installed in the mounting plate. The support frame is U-shaped and fixedly installed above the mounting plate and located between the two pneumatic telescopic rods. A number of mold bases are equidistantly arranged in the support frame. The cavity plate matches the support frame and is arranged above the support frame. The two ends of the cavity plate are connected to the telescopic ends of the pneumatic telescopic rods. A number of cavities matching the mold bases are arranged in the cavity plate.

[0006] Preferably, two groups of connecting slots are symmetrically opened on both sides of the mounting plate.

[0007] Preferably, a limiting block is fixedly arranged at the top of each side of the support frame, and limiting slots matching the limiting blocks are opened on both sides of the cavity plate.

[0008] Preferably, a positioning slot matching the mold base is arranged at the bottom end of the cavity in the cavity plate, and the mold base is embedded in the positioning slot.

[0009] The beneficial effects of adopting the above technical solutions are as follows:

[0010] Through the cooperation of the cavity in the cavity plate and the mold base in the support frame, it is convenient to hot press the brake pad into shape. The pneumatic telescopic rod is used to push the cavity plate upward, so that the cavity is separated from the mold base, thereby facilitating the brake pad to be separated from the cavity, enabling the brake pad to remain in the mold base, and then facilitating the quick removal of the brake pad from the mold by hand tools, improving the work efficiency, and at the same time effectively avoiding scalding the staff.

In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0017] In the description of the present utility model, it should be noted that unless otherwise clearly defined and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, a movable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0018] As Figures 1-3 , in this embodiment, a hot pressing mold for automotive brake pads includes a mounting plate 1, a support frame 2, and a cavity plate 3. Two pneumatic telescopic rods 4 are symmetrically installed in the mounting plate 1. The support frame 2 is U-shaped and fixedly installed above the mounting plate 1 and is located between the two pneumatic telescopic rods 4. A number of mold bases 21 are equidistantly arranged in the support frame 2. The cavity plate 3 matches the support frame 2 and is arranged above the support frame 2. Both ends of the cavity plate 3 are connected to the telescopic ends of the pneumatic telescopic rods 4. A number of cavities 31 matching the mold bases 21 are arranged in the cavity plate 3.

[0019] Through the above technical solution, when in use, the mold is installed in the hot pressing and forming equipment through the mounting plate 1, and then the cavity plate 3 is covered above the support frame 2. At the same time, the cavity 31 in the cavity plate 3 is docked with the mold base 21 to form a mold cavity for hot pressing and forming. Then, the hot pressing and forming work is carried out. After the brake pad is hot pressed and formed, the pneumatic telescopic rod 4 works to push the cavity plate 3 upward, so that the cavity plate 3 is separated from the support frame 2. At the same time, the cavity 31 is separated from the mold base 21, so that the brake pad remains above the mold base 21, which is convenient to remove the formed brake pad with hand tools, improving the material taking efficiency and avoiding scalding. At the same time, when the brake pad stays in the cavity 31, the brake pad can be extruded downward from the upper part of the cavity plate 3 with hand tools, so that the brake pad is separated from the cavity 31, completing the mold unloading.

[0020] Preferably: Two groups of connecting notches 11 are symmetrically arranged on both sides of the mounting plate 1.

[0021] Through the above technical solution, the arrangement of the connecting notches 11 facilitates the installation of the mounting plate 1 in the hot pressing and forming equipment and the loading and unloading of the mold.

[0022] Preferably: A limiting block 22 is fixedly provided at the top of each side of the support frame 2, and limiting grooves 32 matching the limiting blocks 22 are provided on both sides of the cavity plate 3.

[0023] Through the above technical solution, the arrangement of the limiting block 22 at the top of the support frame 2 and the limiting groove 32 in the cavity plate 3 facilitates the connection and limitation of the cavity plate 3 and the support frame 2, thus ensuring the stability during hot pressing and forming.

[0024] Preferably: A positioning groove 311 matching the mold base 21 is provided at the bottom end of the cavity 31 in the cavity plate 3, and the mold base 21 is embedded in the positioning groove 311.

[0025] Through the above technical solution, the arrangement of the positioning groove 311 enables the cavity 31 in the cavity plate 3 and the mold base 21 to form a sealed cavity, thus facilitating hot pressing and forming.

[0026] Finally, it should be noted that: The above embodiments are only used to illustrate the present invention, rather than limiting the technical solutions described in the present invention; Therefore, although this specification has described the present invention in detail with reference to the above-mentioned various embodiments, those of ordinary skill in the art should understand that the present invention can still be modified or equivalently replaced. All technical solutions and their improvements that do not depart from the spirit and scope of the present invention should be covered within the scope of the claims of the present invention; The technologies not described in detail in the present invention are implemented with existing technologies.
