Description

Technical Field

[0001] This utility model relates to the field of brake pad manufacturing technology, specifically to a brake pad demolding and unloading mechanism. Background Technology

[0002] In the brake pad manufacturing industry, conventional molding processes require the use of molding machines. During manufacturing, metal powder raw materials are first injected into a specific mold, and then pressure is applied to the raw materials through the extrusion mechanism of the molding machine, causing the raw materials to solidify and form a semi-finished brake pad within the mold cavity. After the molding process is completed, the molded brake pads must be removed from the mold and unloaded before they can proceed to subsequent processing stages to ensure the continuity of the production process.

[0003] In existing technologies, the demolding and unloading of brake pads mostly relies on manual operation. This method has significant shortcomings: First, the extrusion device of the molding machine is always in a high-risk operating area during the operation cycle. Operators need to put their limbs into this area to perform demolding and unloading operations, which is very easy to come into contact with the extrusion mechanism, posing a very high safety risk. Second, manual demolding requires operating on each mold one by one. Not only is the operation time-consuming and labor-intensive, but the speed and stability of manual operation are also difficult to control, which can easily lead to the unloading rhythm not matching the previous molding process, causing production interruption and affecting overall production efficiency. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a brake pad demolding and unloading mechanism to solve the problem that the demolding and unloading of brake pads in the prior art relies on manual labor.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a brake pad demolding and unloading mechanism, comprising: a molding machine; a chassis disposed on the molding machine, the chassis having a unloading groove; a molding disc rotatably connected to the chassis, the molding disc having a mold groove; a first extrusion section and a second extrusion section disposed on the molding machine, the first extrusion section and the second extrusion section respectively having a first mold and a second mold, the first mold and the second mold being arranged perpendicularly.

[0006] Optionally, a feeding section is fixed to the molding machine near the second extrusion section, and the feeding section has a feeding channel; a collecting section is located at the outlet of the feeding channel.

[0007] Optionally, it further includes: a lead screw, one end of which is rotatably connected to the molding machine and the other end of which is rotatably connected to the unloading part; and a drive source, which is fixed to the molding machine and connected to the lead screw via a reducer.

[0008] Optionally, the chassis is threadedly connected to the lead screw, the chassis has a third region and a fourth region, the material discharge groove is opened in the fourth region, and a convex shaft is also fixed on the chassis.

[0009] Optionally, the forming disc is sleeved outside the convex shaft, the forming disc has a first region and a second region, and the mold groove is formed in the first region.

[0010] Optionally, a support column is fixed on the molding machine, and the first extrusion section is connected to the support column through a buffer section; a fixing section is fixed on the feeding section, and the second extrusion section is also connected to the fixing section through a buffer section.

[0011] Optionally, the buffer includes a first connecting block, a second connecting block, and a third connecting block. The second connecting block and the third connecting block are fixedly connected. A rod is fixed on the first connecting block. The rod passes through the second connecting block and is fixedly connected to a limiting part. A spring is sleeved on the rod. The two ends of the spring abut against the first connecting block and the second connecting block, respectively.

[0012] Optionally, the first extrusion section includes a first extrusion plate fixed to the first connecting block and a first fixing plate fixed to the second connecting block, the first mold being fixed to the first extrusion plate and the first mold passing through the first fixing plate and sliding thereon.

[0013] Optionally, the second extrusion section includes a second extrusion plate fixed to the first connecting block and a second fixing plate fixed to the second connecting block, the second mold being fixed to the second extrusion plate and the second mold passing through the second fixing plate and sliding thereon.

[0014] Optionally, the collection section includes a collection buffer medium.

[0015] The beneficial effects of this utility model are as follows: In this invention, during demolding and unloading, a lead screw drives the chassis to move the forming disc to the corresponding position of the second extrusion section. The rotation of the forming disc then achieves precise alignment and overlap between the unloading groove, the extrusion groove, and the second mold. At this point, pressing down on the second extrusion section smoothly extrudes the finished brake pad formed in the extrusion groove from the unloading groove, completing the demolding and unloading operation. This demolding and unloading method requires no direct manual intervention, avoiding the risk of operators being exposed to the high-risk operating areas of the molding machine. Simultaneously, the automated batch demolding and unloading mode ensures efficient connection between the demolding and unloading action and the preceding molding process, preventing production interruptions and improving overall production efficiency and operational stability.

[0016] Meanwhile, the chassis of this utility model has a third region and a fourth region. The material discharge groove is located in the fourth region, the forming plate has a first region and a second region, and the mold groove is located in the first region. During the stamping stage, the mold groove and the material discharge groove are staggered to form a closed and regular forming area. When demolding and unloading are required, rotating the forming plate relative to the chassis allows the mold groove and the material discharge groove to precisely overlap, forming a smooth and unobstructed unloading area. This ensures that the brake pad can be smoothly discharged along a preset path, achieving efficient switching between forming and unloading functions.

[0017] In addition, this utility model also includes a feeding section with a feeding channel inside. A collecting section, filled with a collecting buffer medium, is located at the outlet of the feeding channel. After the brake pads are demolded and fed, they smoothly enter the collecting section through the guiding action of the feeding channel. The collecting buffer medium effectively absorbs the impact force during the brake pads' descent, preventing structural damage and protecting the brake pads, thus ensuring production efficiency and product quality stability.

[0026] 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.

[0027] As mentioned earlier, in the existing technology, the demolding and unloading of brake pads mostly relies on manual operation. This mode has significant shortcomings: on the one hand, the extrusion device of the molding machine is always in a high-risk working area during the operation cycle. Operators need to put their limbs into this area to perform demolding and unloading operations, which is very easy to come into contact with the extrusion mechanism, posing a very high safety risk; on the other hand, manual demolding requires operating on each mold one by one. Not only is the operation time-consuming and laborious, but the speed and stability of manual operation are also difficult to control, which can easily lead to the unloading rhythm not matching the previous molding process, causing production interruption and thus affecting the overall production efficiency.

[0028] To address this issue, this invention provides a demolding and unloading mechanism for brake pad production. By rapidly switching between the molding and demolding processes, the aforementioned problems are solved, achieving efficient and safe operation for brake pad demolding and unloading. This invention solves the problem in the following ways.

[0029] Example 1: Please refer to the accompanying drawings in the specification. This embodiment provides a brake pad demolding and unloading mechanism, which includes, as shown in the figures below. Figures 1 to 2 The molding machine 1 shown is equipped with four support columns 12 fixed to its main body. A cylinder platform is fixed to the top of each support column 12, and a cylinder is fixed to the cylinder platform. A drive source (e.g., a motor) and a reducer are also fixed to the molding machine 1.

[0030] like Figure 1As shown in this embodiment, a feeding section 6 is fixed on the front end face (i.e., the side away from the drive source) of the molding machine 1. The feeding section 6 has an opening facing the top and an opening facing the front, which extend towards each other to form an inclined feeding channel. At the front opening, the mechanism is also provided with a collecting section 7. Therefore, in use, the molded brake pad product enters the feeding channel through the top opening, slides along the inclined feeding channel, and finally slides out from the front opening and is collected by the collecting section 7.

[0031] like Figure 1 As shown in this embodiment, in this first embodiment, a lead screw 11 is provided on both sides of the main body of the molding machine 1. A rod seat is rotatably connected to both sides of the lead screw 11. One end of the rod seat is fixed to the main body of the molding machine 1, and the other end is fixed to the top end face of the feeding section 6. Simultaneously, a transmission wheel (e.g., a sprocket or pulley) is fixed to one end of the lead screw 11, and these two transmission wheels are connected by a transmission belt (e.g., a chain or belt). One of the lead screws 11 is connected to the output end of a reducer. Therefore, in use, the drive source is connected to the reducer, and the reducer transmits power to the lead screw 11, causing both lead screws 11 to rotate.

[0032] like Figures 1 to 4 As shown in the first embodiment, the molding machine 1 is also provided with a chassis 2. The chassis 2 is threadedly connected to the lead screw 11. When the lead screw 11 rotates, it moves along the lead screw 11 under the action of the thread. As the rotation direction of the lead screw 11 is different, the chassis 2 moves back and forth on the molding machine 1 and the unloading part 6.

[0033] The chassis 2 has four areas: two third areas 21 and two fourth areas 22, such as... Figure 3 As shown, the two third regions 21 are arranged opposite each other, and the two fourth regions 22 are also arranged opposite each other, with several material feeding grooves 23 opened in the fourth region 22. A convex shaft 24 is fixed in the middle of the top end face of the chassis 2, and the forming disk 3 is rotatably connected to the convex shaft 24 through a bearing.

[0034] like Figure 3 As shown, in this first embodiment, the molding disc 3 also has four regions: two first regions 31 and two second regions 32. Vertically, the first region 31 corresponds to the position of the third region 21, and the second region 32 corresponds to the position of the fourth region 22. Several mold grooves 33 are formed within the first region 31. The molding disc 3 is rotatable relative to the base 2. Therefore, when the molding disc 3 rotates, it forms, but is not limited to, the following states: In the first state, the mold groove 33 and the material feeding groove 23 are staggered. In this first state, a closed molding chamber (molding area) is formed between the internal space of the mold groove 33 and the third area 21. The bottom space of the mold groove 33 is also fixed with a sealing strip for sealing. This sealing strip can seal the area between the chassis 2 and the molding disc 3, so that the molding chamber is sealed, or not sealed but in an acceptable closed state. When rotating, applying a force to the molding disc 3 to overcome the damping of the sealing strip can drive it to rotate. In use, metal powder is added into it, and then the molding of the brake pad is completed by applying pressure to the metal powder inside the molding chamber from above by a cylinder.

[0035] In the second state, the forming disc 3 rotates 90°, causing the mold groove 33 and the material discharge groove 23 to overlap, forming a vertically connected material discharge chamber between them. At this time, the finished brake pad inside the material discharge chamber is brought into contact from above, causing it to detach and completing the material discharge.

[0036] Therefore, in the specific implementation of this embodiment, the initial position of the chassis 2 should be above the unloading section 6. At this time, the forming disc 3 is in the first state. Subsequently, metal powder is added into the forming chamber, and the drive source drives the lead screw 11 to rotate, pushing the chassis 2 and the forming disc 3 under the cylinder for forming. After forming is completed, the lead screw 11 flips, pushing the chassis 2 and the forming disc 3 back onto the unloading section 6. At this time, the forming disc 3 is rotated manually (or by the drive mechanism) to enter the second state. In the second state, the finished brake pads fall from the unloading chamber and enter the unloading channel in the unloading section 6, and are finally collected by the collecting section 7.

[0037] Example 2: Based on the above embodiments, in order to further clarify and completely explain the technical solutions therein, this utility model also provides an embodiment two. For example... Figures 3 to 6 As shown, in this second embodiment, the molding machine 1 has a first extrusion section 4 on its main body, and a plurality of first molds 43 on the first extrusion section 4; the unloading section 6 has a second extrusion section 5, and a plurality of second molds 53 on the second extrusion section 5. During molding, pressure is applied to the first extrusion section 4 by a cylinder, causing the first molds 43 to enter the molding chamber and apply pressure to the metal powder to complete the molding process. During demolding and unloading, pressure is applied to the second extrusion section 5 by a cylinder or manually, causing the second molds 53 to enter the unloading chamber and abut against the finished brake pad to complete the demolding process.

[0038] Specifically, such as Figure 6As shown, in this second embodiment, the first extrusion part 4 includes a first extrusion plate 41, a first mold 43 is fixed on the first extrusion plate 41, and the first extrusion part 4 also includes a first fixing plate 42, the first mold 43 passes through the first fixing plate 42 and slides within the first fixing plate 42.

[0039] At the same time, such as Figure 4 or Figure 5 As shown, a first connecting block 81 is fixed on the first pressing plate 41, a second connecting block 82 is fixed on the first fixing plate 42, and a third connecting block 83 is fixed on the support column 12. The third connecting block 83 and the second connecting block 82 are fixedly connected, and a rod 84 is fixed on the first connecting block 81. The rod 84 passes through the second connecting block 82 and is fixed with a limiting part 86 to prevent it from detaching from the second connecting block 82. A spring 85 is also sleeved on the outside of the rod 84, and the two ends of the spring 85 abut against the first connecting block 81 and the second connecting block 82 respectively (the first connecting block 81, the second connecting block 82, the third connecting block 83, the rod 84, the spring 85, and the limiting part 86 together form a buffer part 8). Figure 3 As shown, the first mold 43 and the feeding trough 23 are set at a 90° angle, that is, the projection of the first mold 43 on the chassis 2 is located in the third region 21.

[0040] Therefore, by applying pressure to the first extrusion plate 41 through the cylinder, the first extrusion plate 41 drives the first mold 43 to move relative to the first fixed plate 42, thereby extending the first mold 43 into the molding cavity to complete the molding process in the first state. When the molding process is completed, the first extrusion plate 41 loses the pressure from the cylinder and resets under the action of the spring 85. After resetting, the first mold 43 rises and exits the molding cavity.

[0041] like Figure 6 As shown, in this second embodiment, the second extrusion section 5 includes a second extrusion plate 51, a second mold 53 fixed on the second extrusion plate 51, and a second fixing plate 52. The second mold 53 passes through the second fixing plate 52 and slides within the second fixing plate 52. Meanwhile, a fixing part 61 is provided on the feeding section 6. The fixing part 61 and the second extrusion section 5 are also connected by a buffer part 8, and the connection method is the same as the connection method between the buffer part 8 and the support column 12 and the first extrusion section 4.

[0042] Unlike the first extrusion section 4, the second mold 53 in the second extrusion section 5 is positioned corresponding to the material discharge groove 23. That is, in the vertical direction, the projection of the second mold 53 onto the chassis 2 is located within the fourth region 22 and coincides with the material discharge groove 23 thereon. Therefore, during use, applying pressure to the second extrusion plate 51 will push the second mold 53 into the material discharge chamber in the second state, thereby pushing the finished brake pad from the material discharge groove 23 to complete demolding and material discharge.

[0043] Example 3: Based on the above embodiments, in order to provide a clearer and more complete explanation of the technical solutions therein, this utility model also provides Embodiment Three. For example... Figure 1 As shown in this third embodiment, the collecting section 7 is also equipped with a collecting buffer medium, such as water, liquid, sand, or foam paper. When the finished brake pad enters the collecting section 7 from the feeding channel, the collecting buffer medium will buffer the impact potential energy of the finished brake pad, thereby preventing it from being damaged.

[0044] Therefore, in summary, compared with the prior art, this utility model and its embodiments have the following advantages, including but not limited to: In this invention, during demolding and unloading, the lead screw 11 drives the chassis 2 to move the forming disc 3 to the corresponding position of the second extrusion section 5. The rotation of the forming disc 3 then achieves precise alignment and overlap between the unloading groove 23, the mold groove 33, and the second mold 53. At this point, pressing down on the second extrusion section 5 smoothly extrudes the finished brake pad formed in the mold groove 33 from the unloading groove 23, completing the demolding and unloading operation. This demolding and unloading method requires no direct manual intervention, avoiding the risk of operators being exposed to the high-risk operating area of ​​the molding machine 1. Simultaneously, the automated batch demolding and unloading mode ensures efficient connection between the demolding and unloading action and the preceding molding process, preventing production interruptions and improving overall production efficiency and operational stability.

[0045] Meanwhile, the chassis 2 of this utility model has a third region 21 and a fourth region 22. The material discharge groove 23 is located in the fourth region 22, and the forming disc 3 has a first region 31 and a second region 32. The mold groove 33 is located in the first region 31. During the stamping stage, the mold groove 33 and the material discharge groove 23 are staggered to form a closed and regular forming area. When demolding and unloading are required, the forming disc 3 is rotated relative to the chassis 2, so that the mold groove 33 and the material discharge groove 23 can be precisely overlapped to form a smooth unloading area, ensuring that the brake pad can be smoothly discharged along the preset path, realizing efficient switching between forming and unloading functions.

[0046] In addition, this utility model also includes a feeding section 6, which has a feeding channel. A collecting section 7 is located at the outlet of the feeding channel and is filled with a collecting buffer medium. After the brake pads are demolded and fed, they smoothly enter the collecting section 7 through the guiding action of the feeding channel. The collecting buffer medium effectively absorbs the impact force during the brake pads' descent, preventing structural damage and protecting the brake pads, thus ensuring production efficiency and product quality stability.

[0047] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
