The inside of the arc-shaped plate is provided with an injection hole, which is connected to the movable cavity. The upper end face of the support bracket is provided with an assembly groove that is adapted to the arc-shaped plate.

[0016] Furthermore, the inner wall of the injection hole is uniformly embedded with multiple sets of limiting protrusions to limit the injection tube, and the limiting protrusions are specifically elastic balls.

[0034] Example 1

[0035] like Figure 1-3 As shown, an auxiliary tooling for machining a dual-cylinder brake caliper includes a support bracket 3. An assembly plate 1 is mounted in the middle of the support bracket 3. An injection pipe 5 is provided on one side of the side end face of the support bracket 3. The assembly plate 1 includes an upper assembly plate 6 and a lower assembly plate 10, which are spliced ​​together. A forming mold 18 is embedded in the middle of the upper assembly plate 6 and the lower assembly plate 10. A forming cavity 15 is opened inside the forming mold 18, which is connected to the injection pipe 5. A rotating latch 7 is provided on the side end face of the assembly plate 1. The assembly plate 1 is rotatably mounted in the middle of the support bracket 3 through the rotating latch 7.

[0036] In use, the system comprises an upper assembly plate 6 and a lower assembly plate 10, with a molding mold 18 for casting embedded in the middle of the upper assembly plate 6 and the lower assembly plate 10. The molding cavity 15 inside the molding mold 18 is connected to the injection pipe 5. The casting liquid is injected through the injection pipe 5, and after cooling and molding, a double-cylinder clamp body is formed. The side end faces of the upper assembly plate 6 and the lower assembly plate 10 are provided with rotating latches 7. By rotating the latches 7, the upper assembly plate 6 and the lower assembly plate 10 can rotate in the middle of the support bracket 3, thereby driving the molding mold 18 to rotate. The centrifugal force generated by the rotation of the molding mold 18 makes the casting liquid inside the molding cavity 15 more evenly distributed, avoiding air bubbles or uneven distribution of casting liquid caused by gravity, thereby improving the finished product quality of the cast double-cylinder clamp body for brakes.

[0037] Example 2

[0038] Based on Example 1, such as Figure 1-3 As shown in Figures 5-6, the upper assembly plate 6 and the lower assembly plate 10 have movable cavities 20 inside. The movable cavity 20 and the molding mold 18 are fitted with a first sealing element 21. The movable cavity 20 and the molding mold 18 are slidably connected inside the upper assembly plate 6 and the lower assembly plate 10 through the movable cavity 20.

[0039] Furthermore, the first seal 21 may be a sealing piston plate or a flexible rubber layer that fits into the movable cavity 20.

[0040] In use, the molding die 18 is slidably disposed inside the movable cavity 20, allowing the device to be quickly replaced as needed, making the device applicable to various molds of different sizes.

[0041] like Figure 1-3 As shown in Figures 3-7, a positioning post 11 is fixedly connected to the mating surface of the upper assembly plate 6 and the lower assembly plate 10, and a positioning groove 14 adapted to the positioning post 11 is provided between the upper assembly plate 6 and the lower assembly plate 10.

[0042] Furthermore, multiple sets of positioning posts 11 may be provided, symmetrically arranged on one side of the upper assembly plate 6 and the lower assembly plate 10.

[0043] In use, the positioning post 11 is provided so that when the upper assembly plate 6 and the lower assembly plate 10 are fitted together, the positioning post 11 and the positioning groove 14 are engaged, which improves the convenience and accuracy of the connection between the upper assembly plate (6) and the lower assembly plate 10.

[0044] like Figure 1-4 As shown, the positioning post 11 has a connecting cavity 29 inside, which is connected to the interior of the movable cavity 20. The positioning post 11 has a second movable cavity 30 on its side end face, which is connected to the connecting cavity 29. The second movable cavity 30 is slidably connected to the interior of the second movable cavity 30.

[0045] like Figure 1-4 As shown, the end of the snap-fit ​​component 16 that fits into the positioning post 11 is provided with a second sealing component 31. The second sealing component 31 separates the connecting cavity 29 and the second movable cavity 30. The inner wall of the positioning groove 14 is provided with a snap-fit ​​groove 19 that engages with the snap-fit ​​component 16.

[0046] Furthermore, the second seal 31 is made of elastic material, and the second seal 31 is fixedly connected to the snap-fit ​​member 16. The end of the snap-fit ​​member 16 facing away from the second seal 31 is set with an inclined surface. Specifically, the contact point between the snap-fit ​​groove 19 and the snap-fit ​​member 16 is a right-angled triangle, with the inclined sides touching each other and locking each other through the right-angled sides.

[0047] In use, the movable cavity 20 is filled with a medium. Injecting the medium causes the molding die 18 to protrude from the surfaces of the upper assembly plate 6 and the lower assembly plate 10 under pressure. As the upper assembly plate 6 and the lower assembly plate 10 press together, the pressure inside the movable cavity 20 increases. Since the connecting cavity 29 is connected to the movable cavity 20, the pressure inside the connecting cavity 29 also increases. The connecting cavity 29 and the second movable cavity 30 are separated by a second seal 31. The second seal 31 is made of an elastic material, causing it to deform towards the interior of the second movable cavity 30 under the pressure of the medium, pushing the snap-fit ​​part 16 to protrude from the positioning post 11. The protruding part of the snap-fit ​​part 16 has a right-angled triangular cross-section. The inclined surface design allows the snap-fit ​​part 16 and... The snap-fit ​​grooves 19 can engage in one direction without affecting the fit between the positioning post 11 and the snap-fit ​​grooves 19. When the upper assembly plate 6 and the lower assembly plate 10 are fully fitted, the internal pressure of the movable cavity 20 is at its maximum. The snap-fit ​​component 16 self-locks the upper assembly plate 6 and the lower assembly plate 10 by engaging the snap-fit ​​grooves 19, avoiding the need for bolts or other mechanical devices for locking and disassembly, which are both cumbersome. As casting progresses, the pressure between the molding cavities 15 increases, which further increases the internal pressure of the movable cavity 20, further improving the locking effect of the snap-fit ​​component 16 and preventing demolding during casting. During demolding, the internal pressure of the movable cavity 20 can be reduced, and the snap-fit ​​component 16 can automatically reset under the elastic force of the second sealing component 31, thereby releasing the locking state between the upper assembly plate 6 and the lower assembly plate 10.

[0048] like Figure 1-9 As shown, the rotating bayonet 7 is composed of two sets of arc-shaped plates 12. The middle part of the arc-shaped plate 12 is provided with an insertion interface 8. The upper assembly plate 6 and the lower assembly plate 10 are provided with a connecting hole 17 for connecting the insertion interface 8 and the forming cavity 15. The inside of the arc-shaped plate 12 is provided with an injection hole 9, which is connected to the movable cavity 20. The upper end face of the support bracket 3 is provided with an assembly groove 2 that is adapted to the arc-shaped plate 12.

[0049] Furthermore, the inner wall of the injection hole 9 is uniformly embedded with multiple sets of limiting protrusions 13 to limit the injection tube 5. The limiting protrusions 13 are specifically elastic balls.

[0050] In use, the two sets of semi-circular arc plates 12 form a rotating bayonet 7, allowing the upper assembly plate 6 or the lower assembly plate 10 to be separated from the support bracket 3 through the assembly groove 2. This facilitates the assembly and separation of the upper assembly plate 6 and the lower assembly plate 10, improving the ease of operation of the device. In addition, there is a liquid injection hole 9 between the arc plates 12. The liquid injection hole 9 is used to limit the injection pipe 5 to prevent the injection pipe 5 from falling off during the casting process, improving the stability of the connection between the injection pipe 5 and the connecting hole 17. At the same time, the medium can be injected into the interior of the movable cavity 20 through the liquid injection hole 9, improving the ease of operation of the device.

[0051] like Figure 1-8 As shown, the support bracket 3 has an injection chamber 28 inside, the injection chamber 28 is connected to the injection pipe 4, and the injection chamber 28 is connected to the injection hole 9.

[0052] In use, the medium is supplied to the inside of the injection chamber 28 through the injection pipe 4. When the rotating jaw 7 engages with the support bracket 3, the injection chamber 28 and the injection hole 9 are in a connected state. The pressure inside the movable chamber 20 can be controlled by connecting the injection pipe 4 to the pressure supply device.

[0053] like Figure 1-8 As shown, the arc-shaped plate 12 at one end of the upper assembly plate 6 and the lower assembly plate 10 has a first movable groove 23 inside. The first movable groove 23 is connected to the injection hole 9. A movable valve plate 24 is slidably embedded inside the first movable groove 23. The movable valve plate 24 is elastically connected to the first movable groove 23 through an elastic element 25.

[0054] Furthermore, the elastic element 25 is a spring or an electromagnetic plate, which can control the position of the movable valve plate 24. The movable valve plate 24 controls the connection or disconnection of the injection hole 9. When the movable valve plate 24 extends into the injection hole 9, the injection hole 9 is in the disconnected state. The medium is injected through the injection pipe 4, that is, the injection hole 9 at the end away from the injection chamber 28 is disconnected, so that the pressure inside the movable chamber 20 can be controlled.

[0055] In use, the first movable groove 23 is elastically embedded inside the first movable groove 23 by the elastic element 25. Under normal circumstances, the first movable groove 23 extends into the injection hole 9 under the elastic force of the elastic element 25, closing the injection hole 9. After the molding mold 18 is poured, the centrifugal force of the assembly plate 1 is used to improve the casting effect. At the same time, as the assembly plate 1 rotates, the movable valve plate 24 inside the first movable groove 23 will move with the centrifugal force of rotation, so that the injection hole 9 inside the arc plate 12 is connected. At this time, by increasing the pressure of the injection pipe 4, the inside of the movable cavity 20 can be connected. The medium flows in from one end near the injection pipe 4 and flows out from the other side. The medium can be a liquid material, so that the internal liquid can flow during the rotation of the assembly plate 1. The bottom of the molding mold 18 is in contact with the first seal 21, which can be made of metal. The flowing liquid medium can quickly cool the molding mold 18, reduce the production time required for the double-cylinder clamp body, and improve the production efficiency of the double-cylinder clamp body. After the assembly plate 1 stops rotating, the movable valve plate 24 will automatically seal the injection hole 9 to maintain the stability of the internal pressure of the movable cavity 20.

[0056] like Figure 1-10 As shown, the support bracket 3 is internally rotatably connected with a drive tooth 26, which is driven by a drive source 27. The outer end face of the arc plate 12 is provided with a tooth groove 22 that meshes with the drive tooth 26.

[0057] Furthermore, the drive tooth 26 is located below the tooth groove 22, and the drive source 27 includes, but is not limited to, rotating drive components such as a motor. The arc plate 12 can partially penetrate the injection chamber 28 and be sealed by a rubber component, so that when the arc plate 12 rotates, the injection hole 9 can also remain in communication with the injection chamber 28.

[0058] In use, the drive source 27 drives the drive teeth 26 to rotate the arc plate 12. The arc plate 12 is spliced ​​to form a circle, so that the drive teeth 26 are always engaged with the tooth groove 22. Thus, the drive source 27 can drive the rotation of the assembly plate 1. The rotation angle of the assembly plate 1 can also be adjusted in real time by controlling the drive source 27, which facilitates the installation and disassembly of the molding mold 18. The device is relatively easy to operate.

[0059] Working principle: The system comprises an upper assembly plate 6 and a lower assembly plate 10, with a molding die 18 embedded in the middle of each plate. The molding cavity 15 inside the molding die 18 is connected to a pouring pipe 5. Casting liquid is injected through the pouring pipe 5, and after cooling and solidification, a double-cylinder clamp body is formed. The upper assembly plate 6 and lower assembly plate 10 have rotating latches 7 on their side faces. Rotating the latches 7 allows the upper assembly plate 6 and lower assembly plate 10 to rotate in the middle of the support bracket 3, thereby rotating the molding die 18. The centrifugal force generated by the rotation of the molding die 18 makes the casting liquid distribution inside the molding cavity 15 more uniform, avoiding air bubbles or uneven casting liquid distribution caused by gravity, thus improving the finished quality of the cast double-cylinder brake clamp body. The molding die 18 is slidably disposed inside the movable cavity 20, allowing the device to be quickly replaced as needed, making it suitable for various molds of different sizes. The positioning post 11 engages with the positioning groove 14 when the upper assembly plate 6 and lower assembly plate 10 are fitted together, improving the convenience and accuracy of the connection between the upper assembly plate (6) and lower assembly plate 10. The movable cavity 20 is filled with a medium. Injecting the medium causes the molding die 18 to partially protrude from the surfaces of the upper assembly plate 6 and lower assembly plate 10 under pressure. As the upper assembly plate 6 and lower assembly plate 10 are pressed together, the pressure inside the movable cavity 20 increases. Furthermore, since the connecting cavity 29 is connected to the movable cavity 20, the pressure increases further. The internal pressure of the connecting cavity 29 increases, and the connecting cavity 29 and the second movable cavity 30 are separated by the second seal 31. The second seal 31 is made of elastic material, which allows it to deform inward into the second movable cavity 30 under the action of medium pressure, pushing the snap-fit ​​part 16 out of the positioning post 11. The cross-section of the protruding part of the snap-fit ​​part 16 is a right-angled triangle. The inclined surface allows the snap-fit ​​part 16 and the snap-fit ​​groove 19 to engage in one direction, without affecting the fit between the positioning post 11 and the snap-fit ​​groove 19. When the upper assembly plate 6 and the lower assembly plate 10 are fully fitted, the internal pressure of the movable cavity 20 is at its maximum, and the snap-fit ​​part 16 self-locks the upper assembly plate 6 and the lower assembly plate 10 through the snap-fit ​​groove 19, avoiding the use of bolts or other mechanical devices. The locking and disassembly processes are quite cumbersome. As casting progresses, the pressure between the molding cavities 15 increases, further increasing the internal pressure of the movable cavity 20. This enhances the locking effect of the snap-fit ​​component 16, preventing demolding during casting. During demolding, simply reducing the internal pressure of the movable cavity 20 allows the snap-fit ​​component 16 to automatically reset under the elastic force of the second seal 31, thus releasing the locking state between the upper assembly plate 6 and the lower assembly plate 10. A rotating latch 7 is formed by two sets of semi-circular arc plates 12, allowing either the upper assembly plate 6 or the lower assembly plate 10 to be separated from the support bracket 3 via the assembly groove 2. This facilitates the assembly and separation of the upper assembly plate 6 and the lower assembly plate 10, improving the ease of operation. Furthermore, injection holes 9 are provided between the arc plates 12.The injection hole 9 is used to limit the injection pipe 5 to prevent it from detaching during casting, thus improving the stability of the connection between the injection pipe 5 and the connecting hole 17. Simultaneously, the injection hole 9 allows for the injection of medium into the movable cavity 20, improving the ease of operation. The injection pipe 4 supplies medium to the injection cavity 28. When the rotating latch 7 engages with the support bracket 3, the injection cavity 28 and the injection hole 9 are in a connected state. By connecting the injection pipe 4 to the pressure supply device, the pressure inside the movable cavity 20 can be controlled. The first movable groove 23 is elastically embedded inside the first movable groove 23 by the elastic element 25. Under normal circumstances, the first movable groove 23 extends into the injection hole 9 under the elastic force of the elastic element 25, closing the injection hole 9. After casting is completed in the molding mold 18, the centrifugal force of the rotating assembly plate 1 improves the casting effect. Simultaneously, as the assembly plate 1 rotates, the movable valve plate 24 inside the first movable groove 23 moves with the centrifugal force, connecting the injection hole 9 inside the arc plate 12. At this time, by raising the injection pipe 4... The pressure allows the medium inside the movable chamber 20 to flow in from one end near the injection pipe 4 and out from the other. The medium can be a liquid material, allowing the liquid inside the assembly plate 1 to flow even during rotation. The bottom of the molding mold 18 is in contact with the first seal 21, which can be made of metal. This allows for rapid cooling of the molding mold 18 through the flowing liquid medium, reducing the production time required for the double-cylinder clamp body and improving production efficiency. After the assembly plate 1 stops rotating, the movable valve plate 24 automatically seals the injection hole 9 to maintain stable pressure inside the movable chamber 20. The drive source 27 drives the drive gear 26 to rotate the arc plate 12. The arc plates 12 are spliced ​​to form a circle, ensuring that the drive gear 26 always meshes with the tooth groove 22. Thus, the drive source 27 can drive the rotation of the assembly plate 1. The rotation angle of the assembly plate 1 can also be adjusted in real time by the drive source 27, facilitating the installation and disassembly of the molding mold 18. The device is easy to operate.
