Description

Technical Field

[0001] This utility model relates to a brake pad lower mold, and in particular to a feeding structure for brake pad manufacturing. Background Technology

[0002] Brake pads are formed by pressing raw material powder into shape in a mold, which is generally divided into an upper mold and a lower mold. The lower mold has multiple cavities. During production, the raw material powder is first filled into these cavities. To ensure that the raw material powder fills the cavities completely, it is usually allowed to extend beyond the cavities before being scraped flat. The scraped-off powder remains on the top surface of the lower mold and needs to be cleaned; otherwise, it will interfere with the closing of the lower and upper molds. This makes the current process of feeding material into the lower mold relatively cumbersome and affects efficiency. Utility Model Content

[0003] This application provides a feeding structure for brake pad manufacturing, which can solve the problems mentioned in the background art.

[0004] This application provides a feeding structure for manufacturing brake pads, comprising: a first plate and a second plate; The first plate has multiple first holes arranged in the horizontal longitudinal and horizontal transverse directions; a material cylinder is also fixed on the top surface of the first plate at the position corresponding to the first hole; and multiple positioning posts are on the bottom surface of the first plate. The second plate has multiple second holes arranged in the horizontal longitudinal and horizontal transverse directions; the top surface of the second plate is attached to the bottom surface of the first plate; the bottom surface of the second plate has no protrusions and is used to fit the top surface of the brake pad lower mold; the second plate is slidably connected to the first plate in the horizontal longitudinal direction, so that the first plate has: a feeding state in which the first hole communicates with the second hole, or a blocking state in which the first hole is blocked by the second plate.

[0005] In some embodiments, multiple sets of fasteners are provided between the second plate and the first plate to enable the second plate to slide relative to the first plate and the top surface of the second plate to be in contact with the bottom surface of the first plate; the fasteners include: countersunk bolts and nuts; the first plate has multiple waist-shaped grooves through which the countersunk bolts pass and slide; the second plate has multiple countersunk holes.

[0006] In some embodiments, a set of fasteners is located on both sides of any first hole in the horizontal direction.

[0007] In some embodiments, for the second plate, there is a connecting groove between multiple second holes in the same row in the horizontal direction, which is used to enable the first plate, the multiple second holes in the same row, and the brake pad lower mold to form a material storage area when the first plate is blocked; the first plate also has multiple pairs of suction holes, which are respectively connected to multiple material storage areas when the first plate is blocked.

[0008] In some embodiments, the multiple positioning posts are divided into two groups, located on both sides of the horizontal transverse bottom surface of the first plate; the outer walls of both sides of the horizontal transverse second plate abut against these two groups of positioning posts.

[0009] In some embodiments, the barrel is frustum-shaped, and its diameter decreases as it approaches the first orifice.

[0011] In summary, this application discloses a feeding structure for brake pad manufacturing, comprising a first plate and a second plate. The feeding structure is installed on the lower mold of the brake pad. With the first plate in a blocking state, raw material powder is fed into various cylinders. The second plate is manually moved, switching the first plate from the blocking state to the feeding state, allowing the raw material powder in the cylinders to enter the mold cavity until it is full. The second plate is then manually moved again, returning the first plate to the blocking state. During this movement, the second plate scrapes the raw material powder in the mold cavity, leaving some powder in the second holes. When the second plate is relatively thin, the amount of powder remaining on the top surface of the lower mold is minimal and does not affect the closing and pressing of the upper and lower molds. The powder on the top surface of the lower mold can be cleaned after multiple cycles. When the second plate is relatively thick, suction holes are provided on the first plate. With the first plate in a blocking state, the raw material powder in the second holes is sucked up through these suction holes. Its beneficial effects include: simple structure and convenient operation, making it easier to add raw material powder to the brake pad lower mold. Attached Figure Description

[0016] Please see Figure 1 and Figure 2 A feeding structure for a brake pad lower mold 5 includes: a first plate 1 and a second plate 2.

[0017] The first plate 1 has multiple first holes 1A arranged in the horizontal longitudinal and horizontal transverse directions, with four rows and four columns as an example in the attached figure. The specific number and spacing of the first holes 1A correspond to the specific number and spacing of the mold cavities in the brake pad lower mold 5.

[0018] A material cylinder 1B is also fixedly installed on the top surface of the first plate 1 at the position corresponding to the first hole 1A. More specifically, the material cylinder 1B and the first plate 1 can be fixed by welding. The material cylinder 1B is used to hold the raw material powder of the brake pad lower mold 5.

[0019] Please see Figure 3 The bottom surface of the first plate 1 has multiple positioning pins 1C. That is, the top surface of the brake pad lower mold 5 has a corresponding number of positioning holes. When the feeding structure is installed on the brake pad lower mold 5, the multiple positioning pins 1C are inserted into the multiple positioning holes one by one, so that the multiple first holes 1A of the first plate 1 are aligned with the multiple mold cavities of the brake pad lower mold 5.

[0020] Please see Figure 2 and Figure 3 The second plate 2 has multiple second holes 2A arranged in the horizontal longitudinal direction and horizontal transverse direction. The specific number and spacing of the second holes 2A are the same as those of the multiple first holes 1A.

[0021] The top surface of the second plate 2 is attached to the bottom surface of the first plate 1. The bottom surface of the second plate 2 has no protrusions and is used to attach to the top surface of the brake pad lower mold 5. That is, after the feeding structure is installed on the brake pad lower mold 5, the sequence from top to bottom is the first plate 1, the second plate 2, and the brake pad lower mold 5.

[0022] The second plate 2 is slidably connected to the first plate 1 along the horizontal longitudinal direction. Through the sliding of the second plate 2 relative to the first plate 1, the first plate 1 has: a feeding state in which the first hole 1A communicates with the second hole 2A, or a blocking state in which the first hole 1A is blocked by the second plate 2.

[0023] Please see Figure 1 In some embodiments, the second plate 2 may have extension portions 2B on both horizontal sides. After the top surface of the second plate 2 is attached to the top surface of the first plate 1, the extension portions 2B can be bent to form a U-shape, covering the corresponding edge of the first horizontal plate, thereby achieving a sliding connection between the second plate 2 and the first plate 1. Accordingly, the second plate 2 is relatively thin.

[0024] Please see Figure 3 and Figure 5The feeding structure is installed on the lower brake pad mold 5. With the first plate 1 in a blocking state, raw material powder is fed into each of the material cylinders 1B. The second plate 2 is manually moved, switching the first plate 1 from the blocking state to the feeding state. The raw material powder in the material cylinders 1B enters the mold cavity until it is full. The second plate 2 is then manually moved again, returning the first plate 1 to the blocking state. During this movement, the second plate 2 scrapes the raw material powder in the mold cavity, leaving some powder in the second hole 2A. The feeding structure is then removed, leaving the powder in the second hole 2A on the top surface of the lower brake pad mold 5. Because the second plate 2 is relatively thin, the amount of powder remaining on the top surface of the lower brake pad mold 5 is minimal and does not affect the closing and pressing of the upper and lower brake pad molds 5. This process can be repeated multiple times before cleaning the powder from the top surface of the lower brake pad mold 5.

[0025] Please see Figure 2 , Figure 4 and Figure 6 In some embodiments, multiple sets of fasteners 3 are provided between the second plate 2 and the first plate 1, and these fasteners 3 are used to realize the sliding of the second plate 2 relative to the first plate 1 and the top surface of the second plate 2 being in contact with the bottom surface of the first plate 1.

[0026] Fastener 3 includes a countersunk bolt 31 and a nut 32. The first plate 1 has multiple slots 1D through which the countersunk bolt 31 passes and slides. More specifically, the countersunk bolt 31 has a smooth section with a relatively larger diameter and a threaded section with a relatively smaller diameter. The smooth section is located within the slot 1D, with a diameter equal to the width of the slot 1D and a height equal to the depth of the slot 1D. The second plate 2 has multiple countersunk holes 2C, which, along with the countersunk bolt 31, prevent the bottom surface of the second plate 2 from protruding.

[0027] The countersunk bolts 31 can be used to press against the inner walls of the two ends of the waist-shaped groove 1D to determine the two limits of movement of the second plate 2. These two limits correspond to the feeding state and the blocking state of the first plate 1, respectively. Accordingly, the second plate 2 needs to have a certain thickness, and the amount of powder remaining on the top surface of the mold 5 under the brake pad will also increase.

[0028] Please see Figure 7 Based on the provision of multiple sets of fasteners 3 between the second plate 2 and the first plate 1, in some embodiments, each of the two horizontal positions of the first hole 1A is a set of fasteners 3.

[0029] During the sliding process of the second plate 2 relative to the first plate 1, the second plate 2 and the first plate 1 can maintain a better fit.

[0030] Please see Figure 8 and Figure 9Based on the provision of multiple sets of fasteners 3 between the second plate 2 and the first plate 1, in some embodiments, for the second plate 2, there are connecting grooves 2D connecting multiple second holes 2A in the same row in the horizontal direction. Through these connecting grooves 2D, the first plate 1, the multiple second holes 2A in the same row, and the brake pad lower mold 5 can form a material storage area 4 when the first plate 1 is blocked. The first plate 1 also has multiple pairs of suction holes 1E, which are connected to multiple material storage areas 4 when the first plate 1 is blocked.

[0031] The second plate 2 scrapes the raw material powder in the mold cavity, leaving some raw material powder in the storage area 4. A suction tube is inserted into one of the suction holes, and air enters from the other suction hole, carrying the raw material powder from the storage area 4 into the suction tube. This process is repeated for multiple storage areas 4, removing the raw material powder, and then the feeding structure is removed.

[0032] Accordingly, the positions of multiple sets of fasteners 3 need to be specifically set. When the first plate 1 is in a blocking state, the waist-shaped groove 1D and the connecting groove 2D should be prevented from communicating. More specifically, the position of each of the first hole positions 1A in the horizontal direction can be a set of fasteners 3.

[0033] Please see Figure 8 In some embodiments, the multiple positioning posts 1C are divided into two groups, located on both sides of the horizontal direction of the bottom surface of the first plate 1. The outer walls of both sides of the second plate 2 abut against these two groups of positioning posts 1C. This facilitates the horizontal positioning of the second plate 2.

[0034] Please see Figure 3 and Figure 5 In some embodiments, the feed cylinder 1B is frustum-shaped, with its diameter decreasing as it approaches the first aperture 1A. This facilitates the downward flow of the raw material powder within the feed cylinder 1B.

[0035] Please see Figure 2 and Figure 4 In some embodiments, one side of the second plate 2 extends beyond the first plate 1 in the horizontal direction, and the extended portion of the second plate 2 also has a gripping hole 2E. This makes it easier to move the second plate 2 manually.
