Description

Technical Field

[0001] This utility model relates to the field of disc brake pad technology, specifically a multi-layer disc brake pad production device. Background Technology

[0002] Multi-layer disc brake pads are brake pads made of multiple layers of different materials. They are mainly used to improve braking performance, thermal stability, durability and braking comfort. The design concept is to overcome the limitations of single-material brake pads through the synergistic effect of multiple materials and meet the braking requirements of high-performance vehicles or harsh operating conditions. Multi-layer disc brake pads are usually formed by pressing.

[0003] In the production of disc brake pads, existing brake pad production equipment often suffers from uneven distribution of raw materials after they are fed into the forming tank, resulting in a low yield rate of brake pads after pressing and forming. At the same time, after the brake pads are formed, the process of demolding them from the mold is difficult, making it hard to remove the formed disc brake pads smoothly from the mold, which affects production efficiency and product quality.

[0004] Therefore, a multi-layer disc brake pad production device is needed to solve the problems in the existing technology, such as uneven raw material feeding during disc brake pad pressing and forming, which leads to a low yield rate and makes it difficult to remove the formed disc brake pads from the mold. Utility Model Content

[0005] The purpose of this invention is to provide a multi-layer disc brake pad production device to solve the problems in the prior art, such as uneven raw material feeding during disc brake pad pressing and forming, resulting in a low yield rate, and the difficulty in removing the formed disc brake pads from the mold.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer disc brake pad production device, including a mounting box and a lower mold fixedly connected to the top surface of the mounting box, wherein an ejection mechanism is provided inside the mounting box, and a striking component is provided on the left outer wall of the mounting box;

[0007] The ejection mechanism includes a movable plate movably disposed within the mounting box, a guide rod fixedly connected to the left side of the mounting box for guidance, an L-shaped plate slidably sleeved on the outer surface of the guide rod, a spring 1 installed between the inner left wall of the mounting box and the L-shaped plate for supporting the L-shaped plate, two parallel movable slots opened on the right side of the mounting box, two movable rods slidably connected within the two movable slots, multiple evenly distributed lifting rods fixedly connected to the top surface of the movable plate, two connecting rods 1 rotatably connected between the movable plate and the L-shaped plate, and two connecting rods 2 rotatably connected between the L-shaped plate and the two movable rods.

[0008] It should be noted in the solution that the striking component includes a mounting plate fixedly connected to the left side of the mounting box, a support plate fixedly connected to the top surface of the mounting plate, a rubber rod slidably mounted on the support plate, a limiting ring fastened to the outer surface of the rubber rod for limiting the movement, a mounting seat fixedly connected to the left side of the rubber rod, a spring set between the support plate and the mounting seat for supporting the mounting seat, multiple rollers rotatably embedded on the left side of the mounting seat, and a motor mounted on the bottom surface of the mounting plate. The output end of the motor rotates through the top surface of the mounting plate and is coaxially fixedly connected to a cam that repeatedly compresses the mounting seat.

[0009] It is worth noting that the bottom surface of the multiple forming grooves on the lower mold is provided with mounting grooves, and a top block can be slidably connected inside each mounting groove.

[0010] Furthermore, it should be noted that two parallel electric actuators are installed on the outer right side of the mounting box, and the output ends of the two electric actuators are fixedly connected to the same connecting plate.

[0011] In one preferred embodiment, the top ends of the plurality of lifting rods slide through the bottom of the corresponding mounting groove and are fixedly connected to the corresponding top block.

[0012] In a preferred embodiment, the two ends of the connecting plate are fixedly connected to two movable rods respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The cam driven by the motor rotates and repeatedly squeezes the mounting seat, causing the rubber rod to continuously strike the lower mold, thereby making the raw material in the molding groove evenly distributed, thus improving the molding yield of brake pads and effectively avoiding the problem of low yield caused by uneven raw material feeding during disc brake pad pressing.

[0015] 2. The connecting plate is moved by the electric push rod, which in turn moves the L-shaped plate by pushing the moving plate through the connecting rod. This causes the top block to push the molded brake pad out of the lower mold, completing the demolding operation. This effectively avoids the problem of the molded disc brake pad being difficult to remove from the mold. Attached Figure Description

[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] Example: Figures 1-4 As shown, this utility model provides a technical solution, including an installation box 1 and a lower mold 2 fixedly connected to the top surface of the installation box 1. An ejection mechanism 3 is provided inside the installation box 1, and a striking component 4 is provided on the left outer wall of the installation box 1.

[0023] The ejection mechanism 3 includes a movable plate 31 movably disposed within the mounting box 1, a guide rod 32 fixedly connected to the left side of the mounting box 1 for guidance, an L-shaped plate 33 slidably sleeved on the outer surface of the guide rod 32, a spring 34 installed between the inner left wall of the mounting box 1 and the L-shaped plate 33 for supporting the L-shaped plate 33, two parallel movable slots 35 opened on the right side of the mounting box 1, two movable rods 36 slidably connected within the two movable slots 35, multiple evenly distributed lifting rods 37 fixedly connected to the top surface of the movable plate 31, two connecting rods 38 rotatably connected between the movable plate 31 and the L-shaped plate 33, and two connecting rods 39 rotatably connected between the L-shaped plate 33 and the two movable rods 36.

[0024] Specifically, when the movable rod 36 moves downward, it pushes the connecting rod 39 to rotate. The connecting rod 39 pushes the L-shaped plate 33 to move. When the L-shaped plate 33 moves, it pushes the connecting rod 38 to rotate, causing the connecting rod 38 to push the moving plate 31 to move upward. When the moving plate 31 moves upward, it pushes the lifting rod 37 to move upward. The lifting rod 37 pushes the molded brake pad out of the lower mold 2, realizing the demolding operation of the molded brake pad and improving the demolding efficiency of the molded brake pad.

[0025] Further as Figure 1 and Figure 3 As shown, it is worth noting that the striking component 4 includes a mounting plate 41 fixedly connected to the left side of the mounting box 1, a support plate 42 fixedly connected to the top surface of the mounting plate 41, a rubber rod 43 slidably mounted on the support plate 42, a limiting ring 44 fastened to the outer surface of the rubber rod 43 for limiting the position, a mounting seat 45 fixedly connected to the left side of the rubber rod 43, a spring 46 disposed between the support plate 42 and the mounting seat 45 for supporting the mounting seat 45, multiple rollers 47 rotatably embedded on the left side of the mounting seat 45, and a motor 48 mounted on the bottom surface of the mounting plate 41. The output end of the motor 48 rotates through the top surface of the mounting plate 41 and is coaxially fixedly connected to a cam 49 for repeatedly pressing the mounting seat 45.

[0026] Specifically, motor 48 drives cam 49 to rotate. Cam 49 cooperates with roller 47 to push mounting base 45 to move. When mounting base 45 moves, it drives rubber rod 43 to strike lower mold 2, so that raw material is evenly distributed in the forming groove on lower mold 2, which can improve the forming quality of brake pad. The second spring 46 is squeezed when mounting base 45 is moved under force and spring 46 contracts under force. As cam 49 rotates, spring 46 pushes mounting base 45 to drive rubber rod 43 to reset. Under the continuous rotation of cam 49, rubber rod 43 repeatedly strikes lower mold 2.

[0027] Further as Figure 2 As shown, it is worth noting that the bottom surface of the multiple forming grooves on the lower mold 2 is provided with mounting grooves 5, and a top block 6 can be slidably connected inside each mounting groove 5.

[0028] Specifically, the top block 6 is initially located inside the mounting groove 5 to prevent the top block 6 from entering the forming groove of the lower mold 2 and interfering with the forming process of the brake pad.

[0029] Further as Figure 1 and Figure 4 As shown, it is worth noting that two parallel electric actuators 7 are installed on the outer right side of the mounting box 1, and the output ends of the two electric actuators 7 are fixedly connected to the same connecting plate 8.

[0030] Specifically, the output end of the electric actuator 7 is fixedly connected to the connecting plate 8, which allows the operator to control the movement of the connecting plate 8 by controlling the electric actuator 7.

[0031] Further as Figure 2 As shown, it is worth noting that the tops of multiple lifting rods 37 slide through the bottom of the corresponding mounting grooves 5 and are fixedly connected to the corresponding top blocks 6.

[0032] Specifically, the lifting rod 37 is fixedly connected to the top block 6. When the moving plate 31 pushes the lifting rod 37 to move, it pushes the top block 6 to move, thus ejecting the formed brake pad from the lower mold 2.

[0033] Further as Figure 4 As shown, it is worth noting that the two ends of the connecting plate 8 are fixedly connected to the two movable rods 36 respectively.

[0034] Specifically, the two ends of the connecting plate 8 are fixedly connected to two movable rods 36 respectively. When the electric push rod 7 pushes the connecting plate 8 to move, the two movable rods 36 move synchronously, thereby pushing the connecting rod 39 to rotate, so as to realize the subsequent ejection and demolding operation.

[0035] In summary, when using this brake pad production device, the raw materials are first fed into the multiple forming grooves on the lower mold 2. Then, the motor 48 is turned on by an external controller, which drives the cam 49 to rotate. When the cam 49 rotates, it works with the roller 47 to squeeze the mounting seat 45. After the mounting seat 45 is subjected to force, it pushes the rubber rod 43 to strike the lower mold 2. At this time, the second spring 46 is in a compressed state. When the cam 49 continues to rotate, the mounting seat 45 is no longer subjected to force, and the second spring 46 pushes the mounting seat 45 to drive the rubber rod 43 to reset. Through the continuous rotation of the cam 49, the rubber rod 43 continuously strikes the lower mold 2, thereby making the raw materials in the forming grooves evenly distributed, thus improving the molding yield of brake pads and effectively avoiding the problem of low yield caused by uneven raw material feeding during disc brake pad pressing.

[0036] After the raw materials are evenly distributed, the upper mold pressing body installed on the top of the mounting box 1 presses the raw materials in the multiple forming grooves on the lower mold 2. After the upper mold and the lower mold are separated, the two electric push rods 7 are activated simultaneously by the external controller. The electric push rods 7 push the connecting plate 8, which drives the two movable rods 36 to move downwards at the same time. The movable rods 36 drive the second connecting rod 39 to rotate. The second connecting rod 39 pushes the L-shaped plate 33 to move, which in turn drives the first connecting rod 38 to rotate. The first connecting rod 38 pushes the moving plate 31, which drives the lifting rod 37 to move upwards, which in turn pushes the top block 6 to move upwards, pushing the formed disc brake pad out of the lower mold 2 and completing the demolding operation. The operation is simple and effectively avoids the problem that the formed disc brake pad is not easy to remove from the mold.

[0037] The motor 48 and the electric actuator 7 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
