Description

Technical Field

[0001] This invention relates to the field of brake pad manufacturing, and more particularly to an automated brake pad processing equipment. Background Technology

[0002] During brake pad production, brake pads need to be hot-pressed and shaped. Existing automated brake pad processing equipment generally uses an ejector method to demold the brake pads, that is, the side wall of the mold hole moves downward while the bottom of the mold hole remains stationary, thus pushing the brake pad out of the mold hole. Although this method can demold the brake pad that is in contact with the side wall of the mold hole, when the side wall of the mold hole pushes the brake pad down, the bottom of the brake pad adheres more tightly to the bottom of the mold hole, causing the bottom of the brake pad to stick to the bottom of the mold hole, making demolding difficult.

[0003] Chinese patent application number CN202221057301.4 discloses a mold for automotive brake pad processing with a rapid demolding function. This device lifts the pressure plate after injection molding, at which point the injection plate is removed from the casting groove. Under the action of spring recovery deformation, a moving block moves upward, pushing a moving plate upward to eject the molded automotive brake pad component, thus achieving rapid demolding of the automotive brake pad component and improving the device's efficiency in quickly demolding automotive brake pad molds. However, after hot pressing, the brake pad is tightly adhered to the mold. Furthermore, the brake pad's structural strength is relatively weak immediately after hot pressing. This device only ejects the brake pad by moving the moving plate upward, failing to pre-separate the tightly adhered portion of the brake pad from the bottom of the mold hole before demolding. This results in the bottom of the brake pad being stuck to the bottom of the mold hole, and forcibly ejecting the brake pad causes tearing and damage to the bottom, leading to defective brake pads and significantly reducing the yield rate. Summary of the Invention

[0013] As a preferred embodiment of the present invention, each spray nozzle is tilted downwards.

[0014] As a preferred embodiment of the present invention, it further includes a vibration system, which includes a second elastic element, a movable block, and a protrusion; a plurality of movable grooves are provided on the support plate; a second elastic element is fixedly connected in each movable groove; a movable block for spreading powder is provided in each movable groove; each movable block is fixedly connected to a corresponding second elastic element; a plurality of clearance grooves are provided on the lower side of the support plate; each clearance groove is horizontally aligned with a corresponding movable block; a plurality of protrusions are provided in each clearance groove.

[0015] Beneficial effects: The present invention realizes that after the top block is pressed down, it rebounds and resets, pushing the brake pad that is stuck to the upper surface of the punch upward, which facilitates the separation of the brake pad from the upper surface of the punch, prevents the brake pad from sticking to the upper surface of the punch, and facilitates the demolding of the brake pad.

[0016] The ejector block drives the ejector plate and ejector rod to spring upward, which in turn lifts the lower front and lower rear parts of the steel backing on the brake pad upward, increasing the thrust when the brake pad separates from the upper surface of the punch, making it easier for the brake pad to separate from the upper surface of the punch and enhancing the demolding effect of the brake pad.

[0017] The first and second rotating parts, which are shaped like the number eight, cause the two adjacent ejector pins to separate to the left and right respectively when they rotate toward the rear of the mold. This increases the distance between the non-connecting ends of the two adjacent ejector pins, thereby enhancing the stability of the two adjacent ejector pins when supporting the brake pads, preventing the brake pads from being intercepted by the mold, and further enhancing the demolding effect of the brake pads.

[0018] The release agent is sprayed downwards from the spray nozzle onto the upper surface of the punch by spraying it downwards. This reduces the adhesion of the release agent to the lower surface of the brake pad and avoids insufficient adhesion of the release agent to the upper surface of the punch and the side wall of the mold hole. This prevents the brake pad from adhering to the punch and mold during the next demolding and further enhances the demolding effect of the brake pad.

[0019] The second elastic element causes the movable block to bounce upwards continuously within the movable groove, striking the bottom of the support plate and causing it to vibrate. This, in turn, causes the powder in the mold hole to be evenly dispersed, preventing voids between the powder particles and avoiding the formation of voids in the hot-pressed brake pads, thus improving the yield of the produced brake pads.

Connected; a mold 5 is provided on the support plate 3, and the mold 5 can be raised and lowered on the support plate 3; the mold 5 has several mold holes that pass through the mold 5 vertically; each punch 4 is located in the corresponding mold hole; each punch 4 is provided with a top block 6, and the top block 6 can be raised and lowered on the punch 4; the mold 5 is provided with a locking component; each top block 6 is equipped with a demolding component; the support plate 3 is provided with a liquid spraying system; after the top block 6 is pressed down and springs back to reset, the brake pads that are stuck to the upper surface of the punch 4 are pushed upward, which makes it easy for the brake pads to separate from the upper surface of the punch 4, prevents the brake pads from sticking to the upper surface of the punch 4, and facilitates the demolding of the brake pads.

[0039] The locking assembly includes a connecting rod 101, a locking rod 102, and a first elastic element 103; the connecting rod 101 is slidably arranged on the right side of the mold 5; several locking rods 102 are fixedly connected to the connecting rod 101; each pair of adjacent locking rods 102 are located on the upper front and upper rear sides of a top block 6; each locking rod 102 has two notches 10201; each punch 4 has two symmetrical first elastic elements 103 fixedly connected to it, the first elastic element 103 being a spring; two adjacent first elastic elements 103 are fixedly connected to the lower side of a top block 6.

[0040] It also includes a drive assembly, which includes a first drive member 104, a second drive member 105, a third drive member 106, a slide rail 107, and an electric slider 108. Two front-to-back symmetrical first drive members 104 are fixedly connected to the right side of the mold 5. The first drive member 104 is an electric push rod. The telescopic ends of the two first drive members 104 are fixedly connected to the connecting rod 101. Four front-to-back symmetrical second drive members 105 are fixedly connected to the support plate 3. The second drive members 105 are electric push rods. The telescopic ends of the four second drive members 105 are fixedly connected to the mold 5. A third drive member 106 is fixedly connected inside the hot press 1. The third drive member 106 is an electric push rod. The telescopic end of the third drive member 106 passes through the support plate 2 and is movably connected to the support plate 3. Two left-to-right symmetrical slide rails 107 are fixedly connected to the support plate 2. An electric slider 108 is slidably connected to each slide rail 107. The two electric sliders 108 are rotatably connected to the rear of the support plate 3.

[0041] The demolding assembly includes a first connecting block 201, a top plate 202, a second connecting block 203, and ejector pins 204. Each top block 6 has a first connecting block 201 fixedly connected to its rear. Each first connecting block 201 has a top plate 202 rotatably connected to its top plate 202. Each top block 6 has a second connecting block 203 fixedly connected to its front. Each second connecting block 203 has two ejector pins 204 rotatably mounted on its left and right sides. When the top plate 202 and ejector pins 204 are lifted upward by the top block 6, the brake pad on the upper surface of the punch 4 is pushed upward, which in turn pushes the upper rear side and the upper front side of the brake pad upward, increasing the thrust when the brake pad separates from the upper surface of the punch 4, making it easier for the brake pad to separate from the upper surface of the punch 4, and enhancing the demolding effect of the brake pad.

[0042] Each top plate 202 has a first guide portion 20201 behind its rotation point; each ejector pin 204 has a second guide portion 20402 behind its rotation point; each punch 4 has a first limiting portion 4003; each first limiting portion 4003 is located behind two adjacent ejector pins 204; each second guide portion 20402 is located below the corresponding first limiting portion 4003; the mold 5 has several second limiting portions 5001; each second limiting portion 5001 is located behind the corresponding top plate 202; each first guide portion 20201 is located below the corresponding second limiting portion 5001; the first limiting portion 4003 controls the second... The guide part 20402 intercepts the ejector rod 204, causing it to rotate towards the rear of the mold 5. Simultaneously, the second limiting part 5001 intercepts the first guide part 20201, causing the top plate 202 to rotate towards the rear of the mold 5. The simultaneous rotation of the top plate 202 and the ejector rod 204 towards the rear of the mold 5 pushes the brake pad upwards, causing the lower rear part of the brake pad to tilt upwards, thereby rotating the brake pad and facilitating its release from the mold 5. At the same time, the ejector rod 204 rotates to the mold hole of the mold 5 and is flush with the upper surface of the mold 5, preventing the brake pad from being intercepted by the mold 5 and ensuring that the brake pad can fall normally into the brake pad collection area behind the hot press 1, further enhancing the demolding effect of the brake pad.

[0043] The upper side of the mold 5 has several recesses 5002; each recess 5002 is located behind the corresponding top plate 202; when the top plate 202 rotates to the rear of the mold 5, the top plate 202 is embedded in the recess 5002 to prevent the top plate 202 from jamming the brake pads and to prevent the brake pads from falling into the brake pad collection area behind the hot press 1.

[0044] Based on a top-down view, the two first rotating parts 20301 on each second connecting block 203 are both in a figure-eight shape; the two second rotating parts 20401 on two adjacent ejector rods 204 are both in a figure-eight shape; the two second guiding parts 20402 on two adjacent ejector rods 204 are both in a figure-eight shape; when two adjacent ejector rods 204 rotate toward the mold 5, the figure-eight-shaped first rotating parts 20301 and second rotating parts 20401 separate them to the left and right respectively, increasing the distance between the non-connecting ends of the two adjacent ejector rods 204, thereby enhancing the stability of the two adjacent ejector rods 204 when supporting the brake pads, preventing the brake pads from being intercepted by the mold 5, and further enhancing the demolding effect of the brake pads.

[0045] Based on a front-to-back view, each second guide 20402 is set in a downward tilted state; when the ejector rod 204 rotates to the rear of the mold 5, the ejector rod 204 is tilted upward by the downward tilted second guide 20402, so that the non-connecting end of the ejector rod 204 is higher than the upper surface of the mold 5, preventing the brake pads from being intercepted by the mold 5, avoiding the brake pads from falling into the brake pad collection area behind the hot press 1 normally, and further enhancing the demolding effect of the brake pads.

[0046] The specific process by which this invention enhances the demolding effect is as follows:

[0047] In the production of brake pads, the electric slider 108 first drives the support plate 3 to slide forward on the support plate 2, thereby moving the punch 4 and mold 5 to the front of the hot press 1. In the initial state, the telescopic end of the second drive member 105 is extended, and the upper surface of the mold 5 is higher than the upper surface of the punch 4. At the same time, the telescopic end of the first drive member 104 is extended, so that the two adjacent locking rods 102 are located at the front and rear of the upper side of the top block 6, respectively, limiting the top block 6. Then, the automatic feeding device moves to the top of the mold 5 and inputs the powder into the mold hole of the mold 5. The automatic feeding device covers the steel back of the brake pad onto each mold hole. Then, the electric slider 108 drives the support plate 3 to slide backward on the support plate 2, thereby moving the punch 4 and mold 5 to the middle of the hot press 1. Then, the hot press 1 is controlled to press down on the mold 5, so that the punch 4 rises in the mold hole of the mold 5 to hot press the powder, so that the powder adheres to the steel back, completing the hot pressing of the brake pad.

[0048] After the brake pads are hot-pressed, they are ready to be demolded. First, the second drive component 105 drives the mold 5 to descend, causing the punch 4 to rise relative to the mold 5 within the mold hole. The punch 4 limits the hot-pressed brake pads. During the descent of the mold 5, the sidewall of the mold hole of the mold 5 gradually separates from the outside of the brake pads. During this process, because the locking rod 102 limits the top block 6, the top block 6 will descend with the mold 5, causing the top plate 202 and the top rod 204 to descend with the mold 5. At the same time, the first elastic element 103 is pushed by the top block. 6. Compression: During the descent of mold 5, an external air pump pumps air into the ventilation groove 3001. The gas then enters the ventilation chamber 4001 through the ventilation groove 3001, thereby exchanging heat and cooling the punch 4, which facilitates the separation of the brake pad from the punch 4. When the top block 6 descends below the air outlet 4002, the gas in the ventilation chamber 4001 is sprayed out through the air outlet 4002 onto the upper surface of the punch 4. The gas then enters the adhesion point between the brake pad and the upper surface of the punch 4, and the gas compression separates the brake pad from the punch 4, enhancing the demolding effect of the brake pad.

[0049] When the mold 5 descends to its lowest point, the first driving member 104 drives the connecting rod 101 to extend, causing the locking rod 102 to slide. This aligns each notch 10201 with the top block 6 on the same vertical line. The top block 6 loses the restraint of the locking rod 102, and the rebound of the first elastic member 103 causes the top block 6 to push the top plate 202 and the ejector rod 204 upward. The top block 6 pushes the brake pads adhered to the upper surface of the punch 4 upward. Simultaneously, the top plate 202 and the ejector rod 204 push the brake pads upward. The lower front and lower rear parts of the upper steel backing are pushed upwards, increasing the thrust when the brake pad separates from the upper surface of the punch 4, facilitating the separation of the brake pad from the upper surface of the punch 4, and enhancing the demolding effect of the brake pad. When the ejector block 6 drives the ejector plate 202 and ejector rod 204 to spring back upwards, the first limiting part 4003 intercepts the second guide part 20402, which is V-shaped and inclined downwards, so that when the two adjacent ejector rods 204 rotate toward the rear of the mold 5, they separate to the left and right respectively into a V-shape. At the same time, through the first limiting part 4003, the second guide part 20402, which is V-shaped and inclined downwards, separates to the left and right respectively. The second limiting part 5001 intercepts the first guiding part 20201, causing the top plate 202 to rotate rearward toward the mold 5 and embed into the corresponding recess 5002, preventing the top plate 202 from jamming the brake pad. Simultaneously, the top plate 202 and the push rod 204 rotate rearward toward the mold 5, pushing the brake pad upward and causing it to rotate. This causes the lower rear part of the brake pad to tilt upward above the upper surface of the mold 5, facilitating the release of the brake pad from the mold 5. At this time, the third driving member 106 extends to support the brake pad. The support plate 3 is lifted to a tilted position towards the rear of the hot press 1, causing the brake pads that have detached from the mold 5 to slide down towards the brake pad collection point behind the hot press 1. During this process, the figure-eight shaped ejector rod 204 rotates to the mold hole on the mold 5, and the non-connecting end of the ejector rod 204 is higher than the upper surface of the mold 5, preventing the brake pads at the front of the upper side of the mold 5 from being intercepted by the mold hole at the rear of the upper side of the mold 5, thus preventing the brake pads from falling into the brake pad collection point behind the hot press 1 normally, and further enhancing the demolding effect of the brake pads.

[0050] After all the brake pads have been demolded, the third drive component 106 is controlled to retract, so that the support plate 3 returns to a horizontal state. The mold 5 is then driven to rise by the second drive component 105. When the locking rod 102 is higher than the front and rear of the top block 6, the first drive component 104 is controlled to extend, so that the notch 10201 and the top block 6 are not on the same vertical line. The locking rod 102 then limits the top block 6 again, thus preparing for the next hot pressing operation.

[0051] Example 2

[0052] Based on Example 1, such as Figures 11-13As shown, the spraying system includes a liquid storage box 301, a transmission pipe 302, a one-way valve 303, and an airbag 304. Two symmetrically arranged liquid storage boxes 301 are fixedly connected inside the support plate 3. Several transmission pipes 302 are fixedly connected to the upper side of each liquid storage box 301. A one-way valve 303 is fixedly connected to each transmission pipe 302. An airbag 304 is fixedly connected to the upper end of each transmission pipe 302. Each one-way valve 303 opens towards the airbag 304 and closes towards the liquid storage box 301. A cavity 6001 is formed inside each top block 6. Several spray nozzles 6002 are provided on the upper part of each cavity 6001. Each airbag 304 is located below the corresponding top block 6 and is connected to the corresponding cavity 6001. The airbags are connected; each airbag 304 is connected to a corresponding cavity 6001 with a one-way diaphragm, which opens towards the cavity 6001 and closes towards the airbag 304; by stretching and expanding the airbag 304, the release agent in the liquid storage box 301 is drawn into the airbag 304 through the transfer pipe 302. When the top block 6 descends and squeezes the airbag 304, the internal volume of the airbag 304 is compressed, and the release agent in the airbag 304 enters the cavity 6001. When the top block 6 bounces up to a height above the upper surface of the punch 4, the release agent in the cavity 6001 is sprayed out from the spray nozzle 6002 to the upper surface of the punch 4 and the mold hole sidewall of the mold 5, thus realizing the loading of the release agent and facilitating the demolding of the brake pad in the next cycle.

[0053] Each spray nozzle 6002 is tilted downwards; this allows the release agent to be sprayed downwards from the nozzle 6002 onto the upper surface of the punch 4, reducing the adhesion of the release agent to the lower surface of the brake pad, avoiding insufficient adhesion of the release agent to the upper surface of the punch 4 and the side wall of the mold hole of the mold 5, and thus preventing the brake pad from adhering to the punch 4 and the mold 5 during the next demolding, further enhancing the demolding effect of the brake pad.

[0054] The specific process of spraying the release agent according to the present invention is as follows:

[0055] When the top block 6 springs upward, it causes the air bladder 304 to stretch and expand, drawing the release agent from the liquid storage box 301 into the air bladder 304 through the transfer pipe 302. When the mold 5 causes the top block 6 to descend, compressing the air bladder 304, the release agent inside the air bladder 304 enters the cavity 6001. When the top block 6 springs upward to a position higher than the upper surface of the punch 4, the release agent inside the cavity 6001 is sprayed outward from the spray nozzle 6002 onto the upper surface of the punch 4 and the side wall of the mold hole in the mold 5. Because the spray nozzle 6002 is inclined downward, it facilitates the release agent to flow out of the spray nozzle 6002. 02 The release agent is sprayed downwards onto the upper surface of the punch 4, reducing the adhesion of the release agent to the lower surface of the brake pad. This prevents insufficient adhesion of the release agent to the upper surface of the punch 4 and the side wall of the mold hole of the mold 5, thereby preventing the brake pad from adhering to the punch 4 and the mold 5 during the next demolding, and further enhancing the demolding effect of the brake pad. During the upward movement of the top block 6, the air bladder 304 is stretched by the top block 6, causing the air bladder 304 to be refilled with release agent. When the second drive component 105 drives the mold 5 to rise, the release agent located at the angle between the upper surface of the punch 4 and the mold hole adheres to the side wall of the mold hole during the upward movement of the mold 5, realizing the feeding of the release agent and facilitating the demolding of the brake pad in the next demolding.

[0056] Example 3

[0057] Based on Example 1, such as Figure 1 and Figure 14 As shown, it also includes a vibration system, which includes a second elastic element 401, a movable block 402, and a protrusion 403; the support plate 2 has two symmetrical movable slots 2001; each movable slot 2001 has a second elastic element 401 fixedly connected to it, the second elastic element 401 being a spring; each movable slot 2001 has a movable block 402; each movable block 402 is fixedly connected to the corresponding second elastic element 401; the support plate 3 has two symmetrical clearance slots 3002 on its lower side; each clearance slot 3002 is horizontally aligned with the corresponding movable block 402; each clearance slot 3002 contains... Each part is equipped with several protrusions 403. When the automatic feeding equipment fills the powder into the mold hole of the mold 5, when the electric slider 108 drives the support plate 3 to slide backward on the support plate 2, several protrusions 403 slide over the upper side of the movable block 402 and press the movable block 402 downward at intervals. Through the second elastic element 401, the movable block 402 bounces upward continuously in the movable groove 2001, knocking on the bottom of the support plate 3, causing the support plate 3 to vibrate, thereby making the powder in the mold hole evenly dispersed, preventing the existence of void areas between the powder, avoiding the brake pads produced by hot pressing having voids, and improving the yield of the produced brake pads.
