Description

Technical Field

[0001] This invention relates to the field of brake pad processing technology, and in particular to a die-casting molding apparatus for processing automotive brake pads. Background Technology

[0002] As a core safety component of the automotive braking system, the molding precision, structural strength, and edge smoothness of automotive brake pads directly determine braking performance and driving safety. Die casting has become the mainstream processing technology for automotive brake pads (especially metal-based or composite material brake pads) due to its advantages of high production efficiency, stable molding quality, and high material utilization.

[0003] In traditional equipment, the die casting and burr removal processes are independent of each other. After die casting is completed, the workpiece needs to be transferred to a special cleaning equipment or manually cleaned with hand tools. This not only increases the process flow time and labor costs, but may also cause surface scratches and edge damage due to workpiece collisions during the transfer process, affecting the product qualification rate. Summary of the Invention

[0004] The technical problem this invention aims to solve is that the die casting and burr removal processes in traditional devices are independent. After die casting, the workpiece needs to be transferred to a dedicated cleaning device or manually cleaned with hand tools. This not only increases process flow time and labor costs, but may also cause surface scratches and edge damage due to workpiece collisions during transfer, affecting product qualification rate. This invention provides a die casting molding device for automotive brake pad processing that can be combined with die casting cleaning, eliminating the need for hand tools and reducing process flow time and labor costs.

[0005] To solve the above problems, the following technical solutions are provided: Design a die-casting molding device for processing automotive brake pads, including a worktable, a feeding module, a turntable, a lower mold assembly, a liquid inlet assembly, a cleaning assembly, and a die-casting assembly; A turntable is fixedly installed on one side of the workbench, a support frame one is fixedly installed on one side of the workbench, a feeding module is fixedly installed on one side of the support frame one, and a support frame two is fixedly connected to one side of the workbench. The lower mold assembly includes a mounting plate, which is fixedly mounted on one side of the turntable. A guide rod is fixedly connected to one side of the mounting plate. One end of the guide rod passes through a sprue plate. An elastic element is sleeved on the side surface of the guide rod. A sprue groove is provided on one side of the sprue plate. A top pressure block is fixedly connected to one side of the mounting plate. A die-casting assembly is disposed above a lower mold assembly. The die-casting assembly includes a pressing block, a movable shell sleeved on the inner wall of the pressing block, a connecting column fixedly connected to one side of the movable shell, a rotating column passing through one side of the movable shell, a rotating shaft sleeved on the side surface of the rotating column, a telescopic rod fixedly connected to the inner wall of the pressing block, and an elastic element sleeved on the side surface of the telescopic rod. The die-casting assembly further includes a striking assembly, which includes a collar that is sleeved with a rotating column. A placement groove is provided on one side of the rotating column. A telescopic rod two is fixedly connected to the inner wall of the placement groove. An elastic element three is sleeved on the side surface of the telescopic rod two.

A movable arm is hinged to one side of the collar. A hinge frame is hinged to one end of the movable arm. A fixed plate is slidably connected to one end of the hinge frame. A striking block is fixedly installed on the inner wall of the hinge frame. One end of the connecting column is fixedly connected to a top plate, and one side of the top plate is fixedly connected to a hydraulic rod. The die-casting assembly further includes a rotating assembly for driving the impact block to rotate. The rotating assembly includes a fixed shell, a limit post two fixedly connected to one side of the fixed shell, a torsion post penetrating one side of the fixed shell, a rotating wheel sleeve rotatably connected to the side surface of the torsion post, a rotating shaft two sleeved on the side surface of the rotating wheel sleeve, a rotating ring fixedly connected to the side surface of the rotating wheel sleeve, an extrusion block hinged to the side surface of the rotating ring, a ratchet sleeved on the side surface of the rotating ring, a coil spring fixedly connected to the side surface of the ratchet, a transmission gear two fixedly connected to one end of the coil spring, a transmission gear one meshing with the side surface of the transmission gear two, and the inner ring surface of the transmission gear one fixedly connected to the side surface of the rotating post.

[0006] The above technical solution utilizes a rotating component that, during the die-casting process, drives a coiled spring via a ratchet to synchronously store energy, converting the indirect pressure of the die-casting process into concentrated mechanical potential energy. Upon release, this energy is instantly converted into the rotational power and reciprocating impact kinetic energy of the striking block. At the end of die-casting, this energy acts on the burrs at the sprue opening and the edge where the workpiece meets the surface, breaking the connection between the burrs and the workpiece body. This avoids the burr residue caused by dispersed power in traditional cleaning methods, and prevents the injury to workers caused by flying debris from striking the burrs. Die-casting cleaning is completed simultaneously, improving die-casting efficiency. Furthermore, the liquid inlet assembly includes a connecting frame one, the inner wall of the connecting frame one being slidably connected to a support frame two, an electric push rod one being fixedly installed inside the connecting frame one, one end of the electric push rod one being fixedly connected to a liquid injection tank, one side of the liquid injection tank being fixedly connected to a connecting pipe, and one end of the connecting pipe being fixedly connected to the discharge end of the feeding module.

[0008] The above technical solution achieves continuous multi-station operation of liquid injection, die casting cleaning, sweeping, and demolding by relying on the intermittent rotation of the turntable. Die casting and burr cleaning are carried out simultaneously without the need for additional process transfers, shortening the process connection time and reducing the single-piece processing cycle compared to traditional equipment, thus meeting the needs of large-scale production.

[0009] Furthermore, the interior of the second connecting frame is equipped with a push rod for driving the connecting slide rail to move downward, and the output end of the second electric push rod is fixedly connected to the moving brush.

This die-casting molding device for automotive brake pads, during the die-casting process, the rotating component drives the coil spring through a ratchet to synchronously store energy, converting the indirect pressure of the die-casting process into concentrated mechanical potential energy. When released, it is instantly converted into the rotational power and reciprocating impact kinetic energy of the striking block. When the die-casting ends, it acts on the burrs at the injection groove opening and the edge of the workpiece, breaking the connection between the burrs and the workpiece body. This avoids the burr residue caused by the dispersion of power in traditional cleaning methods, and the flying debris caused by striking the burrs can injure the workers. The die-casting cleaning is completed simultaneously, improving the die-casting efficiency. 2.

An elastic element 907 is sleeved on the side surface of the telescopic rod 906. The die-casting assembly 9 also includes a striking assembly 920, which includes a collar 9201 that is sleeved with a rotating column 904.

A striking block 9204 is fixedly installed on the inner wall of the hinge frame 9202. One end of the connecting column 903 is fixedly connected to the top plate 12, one side of the top plate 12 is fixedly connected to the hydraulic rod 11, one side of the workbench 1 is fixedly connected to the support frame 10, and the hydraulic rod 11 is fixedly installed on the support frame 10. The die-casting assembly 9 also includes a rotating assembly 930 for driving the impact block 9204 to rotate. The rotating assembly 930 includes a fixed housing 9301, a limit post 9302 fixedly connected to one side of the fixed housing 9301, a torsion post 9303 penetrating one side of the fixed housing 9301, a rotating wheel sleeve 9307 rotatably connected to the side surface of the torsion post 9303, a rotating shaft 9305 sleeved on the side surface of the rotating wheel sleeve 9307, a rotating ring 9308 fixedly connected to the side surface of the rotating ring 9307, a pressing block 9310 hinged to the side surface of the rotating ring 9308, a ratchet 9311 sleeved on the side surface of the rotating ring 9308, and a coil spring fixedly connected to the side surface of the ratchet 9311. 9313, one end of the coil spring 9313 is fixedly connected to a second transmission gear 9306, the side surface of the second transmission gear 9306 meshes with a first transmission gear 9304, the inner ring surface of the first transmission gear 9304 is fixedly connected to the side surface of the rotating column 904, a rubber pad 9309 is fixedly connected to the side surface of the rotating ring 9308, one end of the torsion column 9303 is fixedly connected to a pressing block 901, a volute plate 9312 is movably connected to one side of the second rotating shaft 9305, the coil spring 9313 is sleeved inside the volute plate 9312, and the fixed shell 9301 is fixedly connected to the side surface of the rotating column 904 through a ball bearing. The fixed shell 9301 is divided into upper and lower parts, the upper part of the fixed shell... The interior of 9301 has a limiting groove for limiting the position of the transmission gear 9306 and the ratchet 9311. The pressing block 901 is first aligned with the injection groove 605 on the injection plate 603 of the lower mold assembly. As the hydraulic rod 11 continues to apply pressure, the pressing block 901 contacts the liquid surface. During the die casting process, the fixed plate 9205 contacts the telescopic rod 906 and squeezes the elastic element 907 to move downward. The movable rod 9209 is in contact with the inner wall of the pressing block 901. As the fixed plate 9205 continues to move downward, the movable rod 9209 squeezes the elastic element 9208 inward, which drives the collar 9201 to move upward. The collar 9201 pulls the movable arm 9203. As the moving arm 9203 moves upward, it drives the hinge frame 9202 to slide. At this time, the striking block 9204 moves into the moving shell 902 and enters the pressing block 901. While the fixed plate 9205 moves, one end of the torsion column 9303 is fixed to the pressing block 901 and descends synchronously with the fixed plate 9205. The rotating sleeve 9307 rotates relative to the torsion column, driving the rotating ring 9308 to rotate. The rotating ring 9308 drives the coil spring 9313 to store energy through the ratchet 9311. When the die casting is completed, the hydraulic rod 11 moves upward, and the coil spring 9313 releases power to drive the transmission gear 9306 to rotate, thereby meshing with the transmission gear 9304, so that the rotating column 904 obtains rotational power.

[0021] In this embodiment, the liquid injection assembly 7 includes a connecting frame 701. The inner wall of the connecting frame 701 is slidably connected to the support frame 5. An electric push rod 702 is fixedly installed inside the connecting frame 701. One end of the electric push rod 702 is fixedly connected to the injection tank 703. A connecting pipe 704 is fixedly connected to one side of the injection tank 703. One end of the connecting pipe 704 is fixedly connected to the discharge end of the feeding module 3. The turntable 4 drives a set of lower mold assemblies 6 to rotate to the liquid injection station. The operator first sprays a release agent on the surface of the injection plate 603 and the injection groove 605. The electric push rod 702 drives the injection tank 703 to move along the connecting frame 701 so that the injection port is aligned with the injection groove 605 of the lower mold assembly. The material of the feeding module 3 is transported to the injection tank 703 through the connecting pipe 704. The injection tank 703 injects the die casting raw material into the injection groove 605.

[0022] In this embodiment, the cleaning assembly 8 includes a second connecting frame 801. The inner wall of the second connecting frame 801 is slidably connected to the second support frame 5. An electric push rod 802 is fixedly installed on one side of the second connecting frame 801. A connecting slide rail 803 is movably connected to one side of the second connecting frame 801. A movable brush 804 is slidably connected to the inner wall of the connecting slide rail 803. A limit post 805 is fixedly connected to one side of the connecting slide rail 803. A push rod for driving the connecting slide rail 803 to move downward is installed inside the second connecting frame 801. The output end of the electric push rod 802 is fixedly connected to the moving brush 804. The electric push rod 802 of the cleaning component 8 drives the moving brush 804 to slide along the connecting slide rail 803. At the same time, the push rod in the connecting frame 801 drives the connecting slide rail to descend. The moving brush 804 cleans the burrs and debris remaining on the surface of the lower mold. The limiting post 805 ensures the stability of the moving brush's movement trajectory. The limiting post 805 presses the injection plate 603 to make it move downward, exposing the brake pad surface and reducing the residual burrs and debris inside the injection groove 605.

[0023] This embodiment presents a die-casting molding device for automotive brake pads. Multiple sets of lower mold assemblies 6 are evenly distributed on a turntable 4 on the workbench 1. Initially, each set of lower mold assemblies 6 corresponds to a liquid injection station, a die-casting cleaning station, a demolding station, and a material waiting station, respectively. The turntable 4 is driven by a drive mechanism to rotate intermittently. The turntable 4 drives one set of lower mold assemblies 6 to rotate to the liquid injection station. The operator first sprays a release agent onto the surfaces of the injection plate 603 and the injection groove 605. An electric push rod 702 drives the injection tank 703 to move along the connecting frame 701, aligning the injection port with the injection groove 605 of the lower mold assembly. The material from the feeding module 3 is transported to the injection tank 703 via the connecting pipe 704. The injection tank 703 then injects the die-casting raw material into the injection groove 605. 03. Under the limit of guide rod 602, the system remains horizontal. Elastic element 606 provides pre-tightening force to ensure good sealing during liquid injection. After liquid injection, turntable 4 drives lower mold assembly 6 to rotate to the die casting cleaning station. Hydraulic rod 11 extends to drive top plate 12, connecting column 903, and die casting assembly 9 to descend as a whole. At the same time, hydraulic rod 17 pushes the lower top pressure block 16 to move, causing the upper top pressure block 16 to be lifted upward, passing through rectangular groove 13 and fitting against mounting plate 601. The pressure block 901 first aligns with the injection groove 605 on injection plate 603 of lower mold assembly. As hydraulic rod 11 continues to apply pressure, pressure block 901 contacts the liquid surface. During die casting, fixed plate 9205 contacts telescopic rod 906 and squeezes elastic element 907 towards... As the fixed plate 9205 moves downward, the movable rod 9209 presses against the inner wall of the pressing block 901. Because the fixed plate 9205 continues to move downward, the movable rod 9209 presses inward against the elastic element 9208, causing the collar 9201 to move upward. The collar 9201 pulls the moving arm 9203 upward, and the moving arm 9203 causes the hinge frame 9202 to slide. At this time, the striking block 9204 moves into the moving shell 902 and enters the pressing block 901. Simultaneously with the movement of the fixed plate 9205, one end of the torsion column 9303 is fixed to the pressing block 901 and descends synchronously with the fixed plate 9205. The rotating sleeve 9307 rotates relative to the torsion column, causing the rotating ring 9308 to rotate. The rotating ring 9308 drives the coil spring 9308 through the ratchet 9311. 313 energy storage: After die casting is completed, hydraulic rod 11 moves upward, and coil spring 9313 releases power to drive transmission gear 9306 to rotate, which in turn meshes with transmission gear 9304, giving rotating column 904 rotational power. Movable rod 9209 gradually returns to its initial position through elastic element 9208, and striking block 9204 returns to its outward expansion state, fitting against the inner wall of injection groove 605 to scrape off the burrs at the opening of injection groove 605. When striking block 9204 moves out of the opening of injection groove 605, rotating column 904 rotates, and telescopic rod 9207 and elastic element 9208 drive movable rod 9209 to extend and retract, adjusting the relative position of collar 9201 and rotating column 904, so that striking block 9204 produces a combined rotational and reciprocating striking action, precisely impacting the burrs formed after the brake pad die casting.After burr removal and die casting, the turntable 4 rotates the lower mold assembly 6 to the cleaning station. The electric push rod 802 of the cleaning assembly 8 drives the moving brush 804 to slide along the connecting rail 803. Simultaneously, the push rod inside the connecting frame 801 drives the connecting rail to descend. The moving brush 804 cleans the remaining burrs and debris on the surface of the lower mold. The limiting post 805 ensures the stability of the moving brush's trajectory. The limiting post 805 presses against the gating plate 603, causing it to move downwards and expose the brake pad surface, reducing residual burrs and debris inside the gating groove 605. After cleaning, the turntable 4 rotates the lower mold assembly 6 to the demolding station, where workers press the gating plate 603 to expose the brake pad surface for subsequent demolding operations.
