Description

Technical Field

[0001] This invention relates to the field of pressing machine technology, and in particular to a fully automatic pressing machine for brake pad production. Background Technology

[0002] Brake pads are generally composed of a steel plate, an adhesive heat insulation layer, and a friction layer. The heat insulation layer is made of heat insulation material, while the friction layer is made of friction material, adhesive, etc. In the process of producing brake pads, the heat insulation material and the friction material need to be added into the mold cavity in sequence, and then pressed.

[0003] Current brake pad production equipment uses a feeding device to add heat insulation and friction materials into the mold cavity of a hot press. However, since both heat insulation and friction materials are in powder form, the heat insulation material becomes uneven after being added to the mold cavity. To ensure the separation between the heat insulation and friction materials and the uniformity of the friction layer of the subsequently pressed brake pad, the heat insulation material needs to be leveled. Currently, most methods involve workers or mechanical devices stirring the heat insulation material in the mold cavity to make it smoother. While this can make the distribution of the heat insulation material in the mold cavity more uniform, the problem of unevenness is not well solved. Ultimately, this affects the separation of the heat insulation and friction materials in the mold cavity, resulting in uneven thickness of the friction layer of the produced brake pad and affecting its normal use. Summary of the Invention

[0004] This invention provides a fully automatic pressing machine for brake pad production to solve the problems mentioned in the background art.

The blocks are rotatably connected to a second electric rotating shaft, and the first fixed column is provided with a driving device fixedly connected to the adjacent connecting blocks. The second electric rotating shaft is threadedly connected to a first feeding pipe.

The base plates are used to place the metal back plate and are slidably connected to the adjacent manufacturing mold.

[0006] Furthermore, it is particularly preferred that the connecting mechanism includes a first connecting plate, which is fixedly connected to the first electric rotating shaft. A connecting post is provided on the side of the first connecting plate away from the first electric rotating shaft. Symmetrically distributed elastic telescopic rods are fixedly connected to the side of the connecting post near the circular connecting plate. The telescopic ends of the elastic telescopic rods are fixedly connected to the adjacent base plate.

[0007] Furthermore, it is particularly preferred that a second fixing post is provided on one side of the circular connecting plate, and a fourth electric rotating shaft is rotatably connected to the side of the second fixing post near the circular connecting plate. The fourth electric rotating shaft is provided with threads, and a second feeding pipe is threadedly connected to the fourth electric rotating shaft. The second feeding pipe is slidably connected to the second fixing post and is slidably engaged with the adjacent manufacturing mold.

[0008] Furthermore, it is particularly preferred that a fifth electric rotating shaft is rotatably connected through the middle of both the first and second feeding pipes. The fifth electric rotating shaft is fixedly connected to a flow-limiting block. The two flow-limiting blocks are located inside the first and second feeding pipes respectively and rotate in cooperation with them. The flow-limiting block is provided with two sets of centrally symmetrically distributed grooves. Each set of grooves includes two symmetrically distributed grooves. A first push plate is slidably connected in the groove of the flow-limiting block. A connecting rod is fixedly connected to the opposing sides of the symmetrically distributed first push plates. The connecting rod passes through the adjacent flow-limiting block and the adjacent fifth electric rotating shaft and is slidably connected to both. A shielding ring is slidably connected to the side of the first and second feeding pipes near the circular connecting plate. The first and second feeding pipes are respectively fixedly connected with equidistantly distributed first elastic elements between the first and second feeding pipes and the adjacent shielding rings. The shielding rings are in contact with the adjacent manufacturing mold.

[0009] Furthermore, it is particularly preferred that the inner edge line of the shielding ring, the outer edge line of the first feeding tube, and the outer edge line of the second feeding tube are all the same as the edge line of the upper cavity of the manufacturing mold.

[0010] Furthermore, it is particularly preferred that the second electric rotating shaft is threadedly connected to a second connecting plate, the second connecting plate is slidably connected to the first fixed column, and a vibration motor is fixedly connected to the side of the second connecting plate away from the first fixed column, the vibration motor being in contact with the adjacent base plate.

[0011] Furthermore, it is particularly preferred that the device also includes an electric telescopic rod, which is disposed on one side of the circular connecting plate. The telescopic end of the electric telescopic rod is fixedly connected to a connecting shell, and a heating device is disposed inside the connecting shell. A hydraulic telescopic rod is fixedly connected to the upper side of the connecting shell, and the telescopic end of the hydraulic telescopic rod passes through the connecting shell and is slidably connected thereto. A pressure plate is slidably connected inside the connecting shell, and the telescopic end of the hydraulic telescopic rod is pressed and engaged with the adjacent pressure plate. The connecting shell is connected to a feeding device.

[0012] Furthermore, it is particularly preferred that the connecting shell is fixedly connected to symmetrically distributed fixed shells, the fixed shells are slidably connected to a limiting block inside, the limiting block is limited to the adjacent pressure plate, the limiting block passes through the connecting shell and is slidably connected to it, and a second elastic element is fixedly connected between the fixed shell and the adjacent limiting block.

[0013] Furthermore, it is particularly preferred that a limiting ring is fixedly connected to the upper side of the fixed base, and symmetrically distributed third elastic elements are fixedly connected between the first connecting plate and the adjacent connecting column. The first connecting plate is slidably connected to the adjacent connecting column. A positioning column is fixedly connected to the side of the connecting column near the first electric rotating shaft. The positioning column is limited and engaged with the limiting ring. Two guide frames are evenly distributed on one side of the first electric rotating shaft. One guide frame is slidably connected to an L-shaped moving block, and the other guide frame is slidably connected to a second push plate. A driving device is provided on the side of both guide frames away from the electric telescopic rod.

[0014] Furthermore, it is particularly preferred that the upper side of the limiting ring is set in a stepped shape and is divided into three steps, wherein the second step is located on the lower side of the L-shaped moving block, the third step is located on the lower side of the second push plate, and the remaining positions are all first steps, and adjacent steps are connected by an inclined surface.

[0015] Compared with the prior art, the present invention has at least the following advantages: The present invention uses an electric telescopic plate to flatten the powder in the mold cavity of the manufacturing mold, so that the powder is evenly distributed in the mold cavity, avoiding uneven distribution of friction material after adding friction material to the mold cavity, which would lead to uneven thickness of the friction layer of the brake pad and affect the quality of the brake pad.

[0016] The base plate is driven to vibrate synchronously by a vibration motor, which causes the gas between the powders in the mold cavity to be discharged outward, reducing the spacing between the powders in the mold cavity and increasing the compactness of the powders in the mold cavity.

[0017] The first push plate moves downward under its own weight and the combined weight of the adjacent connecting rod and the symmetrical first push plate, pushing out the powder in the adjacent chute, accelerating the speed at which the powder falls downward in the chute, and at the same time preventing powder from remaining in the chute.

[0018] By pressing the junction of the adjacent pressure plate and brake pad at the wedge-shaped part of the L-shaped moving block, the pressure plate and the adjacent brake pad are separated by lateral shear force, which prevents the brake pad material from adhering to the lower side of the adjacent pressure plate, thus affecting the appearance of the brake pad after molding and its normal use.

[0021] Although the invention may be described with respect to specific applications or industries, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "up," "down," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0022] Currently, in the production of brake pads, after placing the metal backing plate in the mold cavity, heat insulation material needs to be added, followed by friction material. The brake pads are then formed after pressing. However, since both the heat insulation and friction materials are in powder form, the heat insulation material does not tend to be level after being added to the mold cavity. This also prevents the subsequently added friction material from becoming level, ultimately affecting the layering of the heat insulation and friction materials within the mold cavity. Consequently, the thickness of the friction layer in the produced brake pads is uneven, impacting their normal use. To address this problem, this invention proposes the following solution: Example 1: A fully automatic pressing machine for brake pad production, such as... Figures 1-4As shown, the device includes a fixed base 10, on which a first electric rotating shaft 1 is mounted. A feeding device, a pressing device, and a picking device are arranged on one side of the first electric rotating shaft 1. All three devices are electrically connected to a control terminal. The feeding device is used to transport the metal back plate and spray a release agent into the mold cavity. The pressing device is used to press the brake pads. The picking device is used to remove the prepared brake pads. The feeding device, pressing device, and picking device are all existing devices and are not shown in the figure. A circular connecting plate 11 is fixed to the upper side of the first electric rotating shaft 1. The feeding device, pressing device, and picking device are all arranged around the circular connecting plate 11. The circular connecting plate 11 is detachably connected to six circumferentially evenly distributed manufacturing molds 12 (each group of manufacturing molds 12 can have several, but only one is shown in the figure and text; the specific number can be changed according to actual production needs). A first fixing post 13 is provided on the right rear side of the circular connecting plate 11. Two symmetrically distributed connecting blocks 14 are slidably connected to the upper side of the first fixing post 13. The two connecting blocks 14 are rotatably connected to a second electric rotating shaft 15, which is electrically connected to a control terminal. The second electric rotating shaft 15 has symmetrically distributed threaded portions, and the first fixing post 13 is provided with… A drive device fixedly connected to the adjacent connecting block 14 is a conventional device. The illustration uses an electric push rod as an example. The drive device drives the second electric rotating shaft 15 to move synchronously via the transmission of the connecting block 14. A first feeding pipe 16 is threadedly connected to the threaded portion on the upper side of the second electric rotating shaft 15. The first feeding pipe 16 is slidably connected to the first fixed post 13. The second electric rotating shaft 15 drives the first feeding pipe 16 to move via the threaded transmission, adjusting the position of the first feeding pipe 16. The lower end of the first feeding pipe 16 is slidably engaged with the adjacent manufacturing mold 12. The interior of the first feeding pipe 16 stores heat-insulating powder. The heat insulation powder inside the first feeding pipe 16 is guided to the mold cavity of the adjacent manufacturing mold 12. The first feeding pipe 16 is rotatably connected to a third electric rotating shaft 17, which is electrically connected to a control terminal. The third electric rotating shaft 17 is fixedly connected to an electric telescopic plate 18 that is slidably connected to the first feeding pipe 16 and electrically connected to the control terminal. The electric telescopic plate 18 scrapes the material in the mold cavity of the adjacent manufacturing mold 12. The first electric rotating shaft 1 is provided with a uniformly distributed base plate 112 through a uniformly distributed connecting mechanism. The base plate 112 is used to place the metal back plate and is slidably connected to the adjacent manufacturing mold 12.

[0023] like Figure 3 and Figure 4As shown, the connecting mechanism includes a first connecting plate 19, which is fixed to the side wall of the first electric rotating shaft 1. A connecting post 110 is provided on the side of the first connecting plate 19 away from the first electric rotating shaft 1. Two symmetrically distributed elastic telescopic rods 111 are fixed to the upper side of the connecting post 110. The telescopic ends of the elastic telescopic rods 111 are fixed to the adjacent base plate 112. The telescopic ends of the elastic telescopic rods 111 are in the extended position in the initial state, and the distance that the telescopic ends of the elastic telescopic rods 111 can move downward is less than the thickness of the base plate 112. The two adjacent elastic telescopic rods 111 cooperate with each other to maintain the initial position of the adjacent base plate 112. When the base plate 112 moves downward to the position where it contacts the upper side of the fixed part of the two adjacent elastic telescopic rods 111, the upper side of the telescopic ends of the two adjacent elastic telescopic rods 111 is flush with the upper side of the fixed part, and the telescopic ends of the two elastic telescopic rods 111 still have room to move downward, so that the base plate 112 is stable under force during the subsequent pressing process.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, a second fixed post 4 is provided on the left rear side of the circular connecting plate 11. A fourth electric rotating shaft 41 is rotatably connected to the right front side of the second fixed post 4. The fourth electric rotating shaft 41 is electrically connected to the control terminal. The fourth electric rotating shaft 41 is provided with threads. The fourth electric rotating shaft 41 is threadedly connected to a second feeding pipe 42. The second feeding pipe 42 is limited and slidably connected to the second fixed post 4. The second feeding pipe 42 is driven by the fourth electric rotating shaft 41 through the threaded transmission. The second feeding pipe 42 is slidably engaged with the adjacent manufacturing mold 12. The second feeding pipe 42 is used to convey friction material into the mold cavity of the adjacent manufacturing mold 12.

[0025] like Figures 3-7As shown, a fifth electric rotating shaft 2 is rotatably connected through the middle of the first feeding pipe 16 and the middle of the second feeding pipe 42. The fifth electric rotating shaft 2 is electrically connected to the control terminal. A flow limiting block 21 is fixedly connected to the fifth electric rotating shaft 2. The two flow limiting blocks 21 are located inside the first feeding pipe 16 and the second feeding pipe 42 respectively and rotate with them. The flow limiting block 21 is provided with two sets of centrally symmetrically distributed grooves. Each set of grooves includes two symmetrically distributed grooves. The grooves on the flow limiting block 21 transfer the material in the adjacent first feeding pipe 16 or second feeding pipe 42, so that the volume of material transported to the adjacent mold cavity 12 is the same each time. A first push plate 22 is slidably connected in the groove of the flow limiting block 21. A connecting rod 23 is fixedly connected to the opposite side of the symmetrically distributed first push plates 22. The connecting rod 23 passes through the adjacent flow limiting block 21 and the adjacent fifth electric rotating shaft 2 and is slidably connected to them. The two symmetrically distributed first push plates 22 and the adjacent fifth electric rotating shaft 21 are connected to the flow limiting block 21 and the adjacent fifth electric rotating shaft 2. The interaction of the connecting rods 23 causes the first push plate 22 on the lower side to move downward under gravity when the connecting rods 23 are in a vertical state, and squeezes the material in the adjacent groove on the adjacent flow limiting block 21 downward. The first feeding pipe 16 and the second feeding pipe 42 are slidably connected to the side of the circular connecting plate 11. The first feeding pipe 16 and the second feeding pipe 42 are respectively fixed with the adjacent blocking ring 24 with a plurality of first elastic elements 25 distributed at equal intervals. The first elastic elements 25 are springs. The first elastic elements 25 are used to maintain the relative position between the first feeding pipe 16 and the second feeding pipe 42 and the adjacent blocking ring 24. The blocking ring 24 is in contact with the adjacent manufacturing mold 12. The inner edge line of the blocking ring 24, the outer edge line of the first feeding pipe 16 and the outer edge line of the second feeding pipe 42 are the same as the edge line of the mold cavity on the manufacturing mold 12, so as to prevent the material flowing out of the first feeding pipe 16 and the second feeding pipe 42 from leaking outward.

[0026] like Figure 4 As shown, the second electric rotating shaft 15 has a threaded connection to the second connecting plate 3 on its lower threaded portion. During the rotation of the second electric rotating shaft 15, the second connecting plate 3 is driven to move synchronously through the threaded transmission. The second connecting plate 3 is slidably connected to the first fixed column 13. A vibration motor 31 electrically connected to the control terminal is fixed to the left front side of the second connecting plate 3. The vibration motor 31 is in contact with the adjacent base plate 112. The vibration motor 31 transmits the vibration to the mold cavity of the adjacent manufacturing mold 12 through the transmission of the adjacent base plate 112, so that the heat insulation powder in the mold cavity of the adjacent manufacturing mold 12 is vibrated and becomes more compact.

[0027] During the use of this device, the control terminal first starts the feeding device (the feeding device is an existing device, and the workflow will not be described in detail) to transport the processed metal back plate to the left until a metal back plate on the feeding device moves to a position that matches the right-side manufacturing mold 12 and falls into the mold cavity of the right-side manufacturing mold 12 (the metal back plate falling into the mold cavity of the manufacturing mold 12 falls downwards onto the upper side of the adjacent bottom plate 112 and is limited by the bottom plate 112). At the same time, the control terminal shuts down the feeding device, and the feeding device sprays a sufficient amount of release agent into the mold cavity of the manufacturing mold 12. After the release agent is sprayed, the control terminal starts the first electric rotating shaft 1, which drives the upper part of the metal back plate to move to the left. The six first connecting plates 19 and six connecting columns 110 rotate synchronously. The connecting columns 110 drive the adjacent set of elastic telescopic rods 111 to rotate. The two adjacent elastic telescopic rods 111 together drive the adjacent base plate 112 to rotate. At the same time, the first electric rotating shaft 1 drives the circular connecting plate 11 to rotate counterclockwise. The circular connecting plate 11 drives the six manufacturing molds 12 on it to rotate, which in turn drives the metal back plate to rotate. After the circular connecting plate 11 rotates 60°, the control terminal shuts down the first electric rotating shaft 1 and restarts the feeding device to transport the metal back plate on the feeding device to the mold cavity of the manufacturing mold 12 located on the right side. After the transportation is completed, the feeding device is shut down again.

[0028] While the control terminal shuts down the first electric rotating shaft 1, it starts the drive device on the first fixed column 13, which drives the upper connecting block 14 to move to the left front side (hereinafter referred to as...). Figure 1(Based on the perspective of the upper connecting block 14, the upper connecting block 14 drives the second electric rotating shaft 15 to move. The second electric rotating shaft 15 drives the lower connecting block 14 to move synchronously to the left front side. During the movement of the second electric rotating shaft 15, the second electric rotating shaft 15 drives the first feeding tube 16 to move synchronously to the left front side to change the position of the lower end of the first feeding tube 16. When the lower end of the first feeding tube 16 moves to the top of the mold cavity of the right rear manufacturing mold 12, the control terminal shuts down the drive device and simultaneously starts the second electric rotating shaft 15. The second electric rotating shaft 15 drives the first feeding tube 16 to move downward through the threaded transmission. The first feeding tube 16 drives the adjacent blocking ring 24 to move downward synchronously until the blocking ring 24 moves downward to contact the circular connecting plate 11. The feeding tube 16 continues to move downwards, compressing the first elastic element 25 between it and the adjacent shielding ring 24, until the first feeding tube 16 moves downwards to its limit position (i.e., the first elastic element 25 is compressed to its limit state). At this time, the control terminal shuts off the second electric rotating shaft 15. At this time, the lower end of the first feeding tube 16 is located in the mold cavity of the adjacent manufacturing mold 12. Subsequently, the control terminal starts the adjacent fifth electric rotating shaft 2, which drives the adjacent flow limiting block 21 to rotate. The heat insulation powder (hereinafter referred to as powder) in the first feeding tube 16 is transported to the mold cavity of the adjacent manufacturing mold 12 through the through hole on the flow limiting block 21, so as to prevent the powder from leaking outwards along the junction of the lower end of the first feeding tube 16 and the mold cavity of the adjacent manufacturing mold 12. The specific working process is as follows: The powder in the first feed pipe 16 falls downward into the chute on the upper side of the adjacent flow limiting block 21 and onto the adjacent first push plate 22. During the rotation of the flow limiting block 21, the chute on the upper side of the flow limiting block 21 drives the powder inside to move synchronously until the flow limiting block 21 rotates 180°. Then, the chute on the upper side of the flow limiting block 21 rotates to the lower side, and the material inside slides down due to its own gravity. At the same time, the first push plate 22 in the chute moves downward under the combined action of its own gravity and the gravity of the adjacent connecting rod 23 and the symmetrical first push plate 22, pushing the powder in the chute out and accelerating the downward speed of the powder in the chute, while avoiding the residue of powder in the chute.

[0029] After the powder of the specified quality is delivered according to the above operation, the control terminal shuts down the fifth electric rotating shaft 2 and starts the third electric rotating shaft 17. The third electric rotating shaft 17 drives the electric telescopic plate 18 to rotate along the inner wall of the first feeding pipe 16. At the same time, the control terminal starts the electric telescopic plate 18. During the rotation of the electric telescopic plate 18, the electric telescopic plate 18 automatically adjusts its extension length according to the shape of the inner wall of the mold cavity of the manufacturing mold 12 to ensure that the telescopic part of the electric telescopic plate 18 is always in close contact with the inner wall of the mold cavity of the manufacturing mold 12 during the rotation. The electric telescopic plate 18 flattens the powder in the mold cavity of the manufacturing mold 12, so that the powder in the mold cavity of the manufacturing mold 12 is evenly distributed in the mold cavity.

[0030] While the second electric rotating shaft 15 drives the first feeding pipe 16 downward, the first feeding pipe 16 drives the second connecting plate 3 to move upward synchronously. The second connecting plate 3 drives the vibration motor 31 to move upward until the second electric rotating shaft 15 is turned off. At this point, the upper side of the vibration motor 31 moves upward synchronously to a position that contacts the lower side of the adjacent base plate 112. At the same time as the control terminal starts the third electric rotating shaft 17, the vibration motor 31 is started. The vibration motor 31 drives the base plate 112 to vibrate synchronously, causing the gas between the powders in the mold cavity of the manufacturing mold 12 to be discharged outward, reducing the spacing of the powders in the mold cavity of the manufacturing mold 12, increasing the compactness of the powders in the mold cavity of the manufacturing mold 12. At the same time, it cooperates with the electric telescopic plate 18 to make the powders in the mold cavity of the manufacturing mold 12 tend to be flat, avoiding uneven distribution of the material in the subsequent pressing process after adding friction material (hereinafter referred to as material) to the mold cavity of the manufacturing mold 12. This prevents the distribution of the powder from affecting the distribution of the material, which would affect the quality of the brake pads.

[0031] After adjusting the powder in the mold cavity of the right rear mold 12 to a flat state, the control terminal shuts down the third electric rotating shaft 17 and the vibration motor 31, and starts the second electric rotating shaft 15 in reverse. The second electric rotating shaft 15 drives the first feeding pipe 16 and the second connecting plate 3 to return to their initial positions synchronously. After the first feeding pipe 16 and the second connecting plate 3 return to their initial positions, the control terminal shuts down the second electric rotating shaft 15 and starts the drive device on the first fixed column 13 in reverse. The drive device on the first fixed column 13 drives the second electric rotating shaft 15 to return to its initial position through the transmission of the upper connecting block 14. After the second electric rotating shaft 15 returns to its initial position, the control terminal shuts down the drive device on the first fixed column 13 again.

[0032] When the control terminal shuts down the drive device on the first fixed column 13, the control terminal restarts the first electric rotating shaft 1. The first electric rotating shaft 1 drives the circular connecting plate 11 to rotate 60° again. Then, the control terminal shuts down the first electric rotating shaft 1 again. At this time, the manufacturing mold 12 containing powder is located on the left rear side of the device (the specific process is described above). Subsequently, the control terminal starts the fourth electric rotating shaft 41. The fourth electric rotating shaft 41 drives the second feeding pipe 42 to move downward (the specific process is described above), and conveys the material into the mold cavity of the manufacturing mold 12 through the second feeding pipe 42 until the conveying is completed (the specific process is described above). The control terminal then... The control terminal rotates the manufacturing mold 12 by 60° again (the specific process is as described above). At this time, the manufacturing mold 12 is located on the left side of the device. Then, the control terminal starts the pressing device (the pressing device is an existing device, and the workflow will not be described in detail) to press the material and powder in the manufacturing mold 12. After pressing is completed, the material taking device (the material taking device is an existing device, and the workflow will not be described in detail) takes out the pressed brake pads for the next operation. The above operation is repeated to continue to prepare brake pads until the required brake pads are prepared. Then, the control terminal resets the above devices to their initial positions and shuts them down for the next use.

[0033] In this embodiment, the first connecting plate 19 and the adjacent connecting post 110 are fixedly connected, while in subsequent embodiments, the first connecting plate 19 and the adjacent connecting post 110 are slidably connected.

[0034] Considering that the friction material required for brake pads currently has a certain degree of viscosity after heating, it adheres tightly to the inner wall of the mold cavity under the combined action of pressure and heat during the pressing process, which hinders the unloading of the material after pressing. Furthermore, some of the friction material on the surface may adhere to the contact points between the pressing device and the friction material, resulting in an uneven friction layer on the finished brake pad and negatively impacting its quality. Therefore, this invention proposes the following solution to address the above problems: Example 2: Based on Example 1, such as Figure 1 , Figure 2 , Figure 8 and Figure 9As shown, it also includes an electric telescopic rod 5, which is located on the left side of the circular connecting plate 11. The telescopic end of the electric telescopic rod 5 is fixedly connected to a connecting shell 51. A hydraulic telescopic rod 52 is fixedly connected to the upper side of the connecting shell 51. The telescopic end of the hydraulic telescopic rod 52 passes through the connecting shell 51 and is slidably connected to it. A heating device electrically connected to the control terminal is provided inside the connecting shell 51. The heating device is an existing device and is not shown in the figure. The heating device is used to heat the material in the mold cavity of the manufacturing mold 12. A pressure plate 53 is slidably connected inside the connecting shell 51. The cross-sectional shape of the pressure plate 53 is the same as the shape of the mold cavity of the manufacturing mold 12. The pressure plate 53 is used to press the material in the adjacent mold cavity of the manufacturing mold 12. The telescopic end of the hydraulic telescopic rod 52 is pressed and engaged with the adjacent pressure plate 53. The telescopic end of the hydraulic telescopic rod 52 drives the pressure plate 53 to move. The connecting shell 51 is connected to a feeding device (an existing device and not fully shown in the figure) electrically connected to the control terminal. The feeding device is used to replenish the consumed pressure plate 53 in the connecting shell 51.

[0035] like Figure 8 and Figure 9 As shown, the connecting shell 51 is fixedly connected to symmetrically distributed fixed shells 6. The fixed shell 6 has a sliding connection of limit blocks 61 inside. The two limit blocks 61 are in limiting cooperation with the adjacent pressure plates 53. The opposing sides of the two limit blocks 61 are provided with inclined surfaces to limit the adjacent pressure plates 53. The limit blocks 61 pass through the connecting shell 51 and are slidably connected to it. A second elastic element 62 is fixedly connected between the fixed shell 6 and the adjacent limit blocks 61. The second elastic element 62 is a spring, which is used to drive the moved limit blocks 61 to reset to the initial position.

[0036] like Figure 2 , Figure 10 and Figure 11As shown, a limiting ring 7 is fixedly connected to the upper side of the fixed base 10. Two symmetrically distributed third elastic elements 71 are fixedly connected between the lower side of the first connecting plate 19 and the upper side of the lower part of the adjacent connecting column 110. The first connecting plate 19 is slidably connected to the adjacent connecting column 110. The third elastic element 71 is a spring, used to maintain the initial position of the adjacent connecting column 110 and to drive the moved connecting column 110 back to the initial position. A positioning column 72 is fixedly connected to the side of the connecting column 110 near the first electric rotating shaft 1. The positioning column 72 is limited and engaged with the limiting ring 7. The upper side of the limiting ring 7 is set in a stepped shape and is divided into three steps. The second step is located under the L-shaped moving block 74, the third step is located under the second push plate 75, and the remaining positions are all first steps. Adjacent steps are connected by an inclined surface. For limiting the positioning post 72, two evenly distributed guide frames 73 are provided on one side of the first electric rotating shaft 1. The left front guide frame 73 is slidably connected to an L-shaped moving block 74. The horizontal part of the L-shaped moving block 74 is provided with a wedge-shaped surface on the side away from the first electric rotating shaft 1, which is used to apply a transverse shearing force between the adjacent pressure plate 53 and the pressed friction material, so that the pressure plate 53 and the pressed friction material are separated. The right front guide frame 73 is slidably connected to a second push plate 75, which is used to remove the pressed brake pad. Both guide frames 73 are provided with a drive device (the drive device is an existing device, and the figure takes an electric push rod as an example) on the side away from the electric telescopic rod 5. The L-shaped moving block 74 and the second push plate 75 are respectively driven by the adjacent drive device and move along the adjacent guide frame 73.

[0037] After the circular connecting plate 11 rotates 180°, the injection mold 12 is located on the left side of the device. Then, the control terminal activates the hydraulic telescopic rod 52. The telescopic end of the hydraulic telescopic rod 52 presses against the adjacent pressure plate 53, causing it to move downwards synchronously. During this downward movement, the pressure plate 53 presses against the inclined surfaces of the two limiting blocks 61, causing them to move away from each other under pressure. The two limiting blocks 61 then press against the adjacent second elastic members 62. This continues until the pressure plate 53 moves downwards to a position where it loses contact with the limiting blocks 61. At this point, the two second elastic members 62 respectively drive the adjacent limiting blocks 61 back to their initial positions. The control terminal resets the pressure plate 53 until it moves downward to contact the material in the adjacent mold cavity 12. Then, the control terminal activates the heating device to heat the material in the mold cavity 12, causing the material in the mold cavity 12 to gather under the combined action of heating and extrusion. After pressing for a specified time, the control terminal reverses and activates the hydraulic telescopic rod 52. The telescopic end of the hydraulic telescopic rod 52 separates from the pressure plate 53, leaving the pressure plate 53 in the mold cavity 12. Then, the control terminal repeats the above operation to make the first electric rotating shaft 1 and other parts connected to it rotate synchronously by 60°.

[0038] During the process of the circular connecting plate 11 rotating another 60°, the following description uses the movement process of the manufacturing mold 12 on the left as an example: During the rotation of the left-side manufacturing mold 12, the adjacent positioning pins 72 are gradually moved upwards by the inclined surface at the junction of the first and second steps on the limiting ring 7. Simultaneously, as the limiting ring 7 moves upwards, it drives the adjacent connecting pins 110 to move upwards synchronously, compressing and storing force in the two adjacent third elastic elements 71. The connecting pins 110, through the transmission of the two adjacent elastic telescopic rods 111, drive the adjacent base plates 112 to move upwards synchronously. The base plates 112 drive the adjacent, pressed brake pads to move upwards, and simultaneously drive the adjacent pressure plates 53 to move upwards, until the positioning pins 72 move upwards to a position where they contact the horizontal surface of the second step on the limiting ring 7. The position post 72 stops moving upward. At this time, the lower side of the pressure plate 53 moves to a position flush with the upper side of the adjacent manufacturing mold 12. Then, the control terminal starts the drive device on the adjacent guide frame 73. The drive device drives the L-shaped moving block 74 to move to the left front side. At the same time, the wedge-shaped part on the left front side of the L-shaped moving block 74 squeezes the junction of the adjacent pressure plate 53 and the brake pad, so that the pressure plate 53 and the adjacent brake pad are separated by lateral shear force. The separated pressure plate 53 is guided by the guide frame 73 to move to the subsequent process flow, so as to avoid the brake pad material adhering to the lower side of the adjacent pressure plate 53, which would affect the appearance of the brake pad after molding and affect the normal use of the molded brake pad.

[0039] After the drive device on the aforementioned guide frame 73 moves to its limit position, the control terminal reverses the drive device and simultaneously restarts the first electric rotating shaft 1. The first electric rotating shaft 1 then drives the circular connecting plate 11 and other parts connected to it to rotate 60° according to the above process. At this time, the manufacturing mold 12 containing the brake pad rotates to the right front side. During the rotation, the positioning post 72 is limited by the inclined surface at the junction of the second and third steps on the limiting ring 7 and moves upward again (the specific movement process can be referred to above). When the positioning post 72 moves to the horizontal plane of the third step on the limiting ring 7, the positioning post 72 stops moving upward. At the same time, the two adjacent third elastic members 71 are compressed again. At this time, the metal back plate of the brake pad moves upward to a position where its lower side is flush with the upper side of the circular connecting plate 11. Then, the control terminal starts the drive device on another guide frame 73. The drive device drives the second push plate 75 to move to the right front side, pushing the prepared brake pad into the adjacent guide frame 73 and guiding it to the next processing position.

[0040] After the prepared brake pads are removed, the control terminal restarts the first electric rotating shaft 1. The first electric rotating shaft 1 drives the other parts connected to it to rotate synchronously by 60° again. Then, the control terminal shuts off the first electric rotating shaft 1. At this time, the manufacturing mold 12 rotates to the right (i.e., the initial position). During the rotation of the manufacturing mold 12, the positioning post 72 gradually moves from the third step of the limiting ring 7 to the first step. As the positioning post 72 gradually moves, the squeezing force of the limiting ring 7 on the positioning post 72 gradually decreases, thereby gradually reducing the squeezing force on the two adjacent third elastic elements 71. The adjacent connecting post 110 moves downward under the combined action of the two adjacent third elastic elements 71 until the positioning post 72 moves to the position where it contacts the upper side of the first step on the limiting ring 7. The positioning post 72 then stops moving, and the adjacent connecting post 110 and the other parts connected to it are reset to the initial height.

[0041] After the manufacturing mold 12 rotates to the right again, a workflow is completed. Once the control terminal has prepared the required brake pads according to the above workflow, the control terminal shuts down the device and cleans it for the next use.
