Rotary disk mold

Abstract

This application relates to the field of stretching die technology and discloses a rotating disk die, including an upper die and a lower die. A second telescopic rod is fixedly installed on the upper surface of the upper die, and a support plate is fixedly connected to the bottom surface of the lower die. This rotating disk die, by incorporating components such as a first telescopic rod, a limiting rod, and mounting blocks, allows the upper die to descend during molding. First, the second telescopic rod is activated, causing the mounting block to slide on the surface of the limiting rod, thereby raising the first and second top blocks to mold the middle position of the raw material. After molding, the upper die is reset via the second telescopic rod. At this time, the first telescopic rod continues to rise, allowing the first and second top blocks to eject the molded rotating disk. This device enables molding and demolding operations to be completed in a single lifting motion with the first telescopic rod, facilitating the removal of the finished product by operators and improving production efficiency.

Description

Technical Field

[0001] This application relates to the field of stretching die technology, specifically rotary disk dies. Background Technology

[0002] A stretching die is a key tool used for the plastic forming of sheet metal. It is a tool that uses a punch and a die to apply force to a flat blank, causing it to undergo plastic deformation to obtain hollow parts of a specific shape and size. Its working principle is based on the ductility of metal. During the stretching process, the punch moves downward and presses into the blank, forcing the material to flow into the die. It goes through stages such as bending, reverse bending, and straight-wall stretching to gradually form the desired shape. The die design needs to comprehensively consider factors such as material properties, part shape, dimensional accuracy, and production batch size, and reasonably determine parameters such as die structure, clearance, and fillet radius to ensure the quality of the stretched parts, avoid defects such as wrinkling and cracking, and improve production efficiency and die life.

[0003] However, in the existing rotary disk mold, it was found that after each stretching and forming of the rotary disk, the formed rotary disk would stick to the lower mold, making it inconvenient for operators to pick up the formed rotary disk. This resulted in excessive time spent picking up the rotary disk and placing the raw material plate, affecting the production efficiency of the rotary disk. Summary of the Invention

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a rotary disk mold that enables molding and demolding operations to be completed in a single lifting motion using a telescopic rod. This facilitates the removal of finished products by operators, reduces the time spent retrieving the rotary disk and placing the raw material plate, and improves production efficiency. It solves the problem in existing technologies where, after each stretching and molding process, the molded rotary disk adheres to the lower mold, making it difficult for operators to retrieve the molded rotary disk and resulting in excessively long retrieval and placement times for the rotary disk and raw material plate, thus affecting the production efficiency of the rotary disk.

[0006] To achieve the above objectives, this application provides the following technical solution: a rotating disk mold, comprising an upper mold and a lower mold, wherein a telescopic rod II is fixedly installed on the upper surface of the upper mold, a support plate is fixedly connected to the bottom surface of the lower mold, and guide rods arranged at equal intervals are slidably connected to the inner wall of the support plate, the outer surface of each guide rod is slidably connected to the inner wall of the upper mold, and the outer surface of each guide rod is fixedly connected to the inner wall of the support plate and the lower mold, a base plate is provided below the lower mold, a telescopic rod I is fixedly installed on the upper surface of the base plate, the bottom end of each guide rod is fixedly connected to the upper surface of the base plate, an installation block is fixedly installed at the output end of the telescopic rod I, two limiting rods are fixedly connected to the upper surface of the base plate, the outer surface of each limiting rod is fixedly connected to the inner wall of the support plate, and the outer surface of each limiting rod is slidably connected to the inner wall of the installation block, two top blocks I are fixedly installed on the upper surface of the installation block, and a top block II is fixedly installed on the upper surface of the installation block.

[0007] The above scheme facilitates the ejection of the formed rotating disk after molding, allowing operators to easily remove it and improving production efficiency. A second telescopic rod is installed on the upper surface of the upper mold. This allows the upper mold to descend, aligning with the lower mold. The fit between the upper and lower molds allows the edge of the rotating disk to be formed. A first telescopic rod is installed on the upper surface of the base plate, with a mounting block fixed to its output end. A limiting rod is also installed on the upper surface of the base plate, connecting to the mounting block to limit its movement. After the edge of the rotating disk is formed, the first telescopic rod drives the mounting block and the top blocks 1 and 2 on the upper surface to lift and form the center of the rotating disk. Once the rotating disk is formed, the upper mold resets, and the first telescopic rod continues to lift the mounting block, allowing the top blocks 1 and 2 to lift the formed rotating disk. This allows the device to directly eject the formed rotating disk after molding, facilitating removal by operators and improving production efficiency.

[0008] Furthermore, a top plate is fixedly connected to the bottom surface of the telescopic rod two, and the outer surface of each guide rod is fixedly connected to the inner wall of the top plate.

[0009] With the above scheme, the top plate is installed on the bottom surface of the telescopic rod two, and the outer surface of the guide rod is fixed to the top plate to support the top plate. In turn, the top plate supports the telescopic rod two. The output end of the telescopic rod two is slidably connected to the inner wall of the top plate, which facilitates the lifting and lowering of the upper mold.

[0010] Furthermore, a pressure plate is slidably connected to the outer surface of the upper mold.

[0011] The above scheme involves placing the pressure plate on the outer surface of the upper mold, with the bottom surface of the pressure plate extending beyond the upper mold, which facilitates pre-pressing and positioning of the raw material on the rotating disk.

[0012] Furthermore, the upper surface of the pressure plate is fixedly connected with equidistantly arranged limiting pins, and the outer surface of each limiting pin is slidably connected to the inner wall of the upper mold.

[0013] The above scheme involves installing a limiting pin on the upper surface of the pressure plate and connecting the surface of the limiting pin to the inner wall of the upper mold in a sliding connection to limit the limiting pin, thereby enabling the pressure plate to rise and fall. When the upper mold descends, the pressure plate first contacts the material, and then the sliding connection between the limiting pin and the upper mold keeps the pressure plate stationary while the upper mold continues to descend until it fits against the pressure plate. At this point, the upper mold shapes the material.

[0014] Furthermore, the inner wall of the lower mold is fixedly connected with fasteners arranged at equal intervals.

[0015] The above method involves installing the fastener on the inner wall of the lower mold, setting it as a fixed connection, and thus achieving the installation of the fastener.

[0016] Furthermore, each of the fasteners has a limiting groove on its upper surface, and an L-shaped plate is slidably connected to the inner wall of each limiting groove.

[0017] The above solution involves creating a limiting groove on the upper surface of the fastener to achieve positioning of the limiting groove. The L-shaped plate is then installed on the inner wall of the limiting groove and configured as a sliding connection. The L-shaped plate can be limited by the contour of the limiting groove.

[0018] Furthermore, each of the L-shaped plates has a sliding rod slidably connected to its inner wall, and the outer surface of each sliding rod is fixedly connected to the inner wall of the corresponding fastener.

[0019] The above solution involves installing the slide rod on the inner wall of the L-shaped plate and setting it as a sliding connection to limit the movement of the slide rod. The outer surface of the slide rod is then fixed to the fixing component to secure the slide rod, thereby enabling secondary positioning of the L-shaped plate.

[0020] Furthermore, a spring is fixedly installed on the upper surface of each L-shaped plate, and the top of each spring is fixedly installed with the inner top wall of the corresponding limiting groove.

[0021] With the above solution, the spring is installed on the upper surface of the L-shaped plate, and the inner top wall of the limiting groove is connected to the top of the spring. The spring facilitates the reset of the L-shaped plate. When the raw material plate is placed on the lower mold, the edge of the L-shaped plate can limit the raw material plate. During the molding operation, the pressure plate can press the L-shaped plate down. After molding is completed, the L-shaped plate is reset under the action of the spring, which can reposition the raw material plate.

[0022] Beneficial effects

[0023] This rotating disk mold, equipped with components such as a telescopic rod, a limiting rod, and mounting blocks, allows for several stages of molding. During molding, the telescopic rod is activated, causing the upper mold to descend and first mold the edges of the raw material plate. Then, the telescopic rod is activated again, allowing the mounting blocks to slide on the surface of the limiting rod. This, in turn, causes the top blocks to rise, molding the center of the raw material plate. After molding, the upper mold is reset via the telescopic rod. Meanwhile, the telescopic rod continues to rise, allowing the top blocks to eject the molded rotating disk. This device enables molding and demolding operations to be completed in a single lift using the telescopic rod, facilitating operation. The operator removes the finished product, improving production efficiency. By setting a spring, the L-shaped plate can be tightened, causing it to bulge. When the operator places the raw material plate, they align the edge of the raw material plate with the L-shaped plate. When the upper mold descends, the pressure plate first contacts the L-shaped plate, causing it to descend and press the raw material plate firmly. At this time, the upper mold continues to descend, and through cooperation with the lower mold, the product forming operation is achieved. After the upper mold resets, the L-shaped plate resets again. This device can position the raw material plate, preventing misalignment or offset when the operator places the raw material plate, thus preventing any impact on the quality of the finished product.

[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0033] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment, the rotating disk mold includes an upper mold 1 and a lower mold 2. A telescopic rod 11 is fixedly installed on the upper surface of the upper mold 1. A support plate 3 is fixedly connected to the bottom surface of the lower mold 2. Guide rods 4 arranged at equal intervals are slidably connected to the inner wall of the support plate 3. The outer surface of each guide rod 4 is slidably connected to the inner wall of the upper mold 1. The outer surface of each guide rod 4 is fixedly connected to the inner wall of the support plate 3 and the lower mold 2. A base plate 5 is provided below the lower mold 2. A telescopic rod 6 is fixedly installed on the upper surface of the base plate 5. The bottom end of each guide rod 4 is fixedly connected to the upper surface of the base plate 5. An installation block 8 is fixedly installed at the output end of the telescopic rod 6. Two limiting rods 7 are fixedly connected to the upper surface of the base plate 5. The outer surface of each limiting rod 7 is fixedly connected to the inner wall of the support plate 3. The outer surface of each limiting rod 7 is slidably connected to the inner wall of the installation block 8. Two top blocks 9 are fixedly installed on the upper surface of the installation block 8. A top block 10 is fixedly installed on the upper surface of the installation block 8.

[0034] Please see Figure 1 , Figure 2 and Figure 3 The bottom surface of the telescopic rod 11 is fixedly connected to the top plate 12. The outer surface of each guide rod 4 is fixedly connected to the inner wall of the top plate 12. The top plate 12 is installed on the bottom surface of the telescopic rod 11, and the outer surface of the guide rod 4 is fixed to the top plate 12 to support the top plate 12. In turn, the top plate 12 supports the telescopic rod 11. The output end of the telescopic rod 11 is slidably connected to the inner wall of the top plate 12 to facilitate the lifting and lowering of the upper mold 1.

[0035] Please see Figure 4 A pressure plate 13 is slidably connected to the outer surface of the upper mold 1. The pressure plate 13 is set on the outer surface of the upper mold 1, and the bottom surface of the pressure plate 13 extends beyond the upper mold 1, so as to pre-press and position the raw material of the rotating disk.

[0036] Please see Figure 4The upper surface of the pressure plate 13 is fixedly connected with equidistantly arranged limiting pins 14. The outer surface of each limiting pin 14 is slidably connected to the inner wall of the upper mold 1. The limiting pins 14 are installed on the upper surface of the pressure plate 13, and the surface of the limiting pins 14 is connected to the inner wall of the upper mold 1 in a sliding connection to limit the limiting pins 14, thereby enabling the pressure plate 13 to rise and fall. When the upper mold 1 descends, the pressure plate 13 first contacts the material, and then the pressure plate 13 remains stationary due to the sliding connection between the limiting pins 14 and the upper mold 1. The upper mold 1 continues to descend until the upper mold 1 and the pressure plate 13 are in contact, at which point the upper mold 1 shapes the material.

[0037] Please see Figure 5 and Figure 6 The inner wall of the lower mold 2 is fixedly connected with fasteners 15 arranged at equal intervals. The fasteners 15 are installed on the inner wall of the lower mold 2 to form a fixed connection, thereby realizing the installation of the fasteners 15.

[0038] Please see Figure 6 Each fastener 15 has a limiting groove 17 on its upper surface, and an L-shaped plate 18 is slidably connected to the inner wall of each limiting groove 17. The limiting groove 17 is opened on the upper surface of the fastener 15 to achieve positioning of the limiting groove 17. The L-shaped plate 18 is installed on the inner wall of the limiting groove 17 and is set as a sliding connection. The L-shaped plate 18 can be limited by the contour of the limiting groove 17.

[0039] Please see Figure 6 Each L-shaped plate 18 has a sliding rod 16 slidably connected to its inner wall. The outer surface of each sliding rod 16 is fixedly connected to the inner wall of the corresponding fixing member 15. The sliding rod 16 is installed on the inner wall of the L-shaped plate 18 and set as a sliding connection to limit the sliding rod 16. The outer surface of the sliding rod 16 is fixed to the fixing member 15 to fix the sliding rod 16, thereby enabling secondary limiting of the L-shaped plate 18.

[0040] Please see Figure 6 Each L-shaped plate 18 has a spring 19 fixedly installed on its upper surface. The top of each spring 19 is fixedly installed to the inner top wall of the corresponding limiting groove 17. The spring 19 is installed on the upper surface of the L-shaped plate 18, and the inner top wall of the limiting groove 17 is connected to the top of the spring 19. The spring 19 facilitates the reset of the L-shaped plate 18. When the raw material plate is placed on the lower mold 2, the edge of the L-shaped plate 18 can limit the raw material plate. During the molding operation, the pressure plate 13 can press down the L-shaped plate 18. After molding is completed, the L-shaped plate 18 is reset under the action of the spring 19, and the raw material plate can be repositioned.

[0041] In this embodiment, the rotating disk mold, through the inclusion of components such as a telescopic rod 6, a limiting rod 7, and a mounting block 8, allows the upper mold 1 to descend during molding by activating the telescopic rod 11. This first shapes the edges of the raw material plate. Then, activating the telescopic rod 6 allows the mounting block 8 to slide on the surface of the limiting rod 7, thereby causing the top blocks 9 and 10 to rise and shape the center of the raw material plate. After molding, the upper mold 1 returns to its original position via the telescopic rod 11. At this time, the telescopic rod 6 continues to rise, allowing the top blocks 9 and 10 to eject the molded rotating disk. This allows the device to complete molding and demolding operations with a single lift of the telescopic rod 6, facilitating operation. The operator removes the finished product, improving production efficiency. The L-shaped plate 18 is tightened by the spring 19, causing it to bulge. When the operator places the raw material plate, the edge of the raw material plate is aligned with the L-shaped plate 18. When the upper mold 1 descends, the pressure plate 13 first contacts the L-shaped plate 18, causing it to descend and press the raw material plate firmly. At this time, the upper mold 1 continues to descend, and through cooperation with the lower mold 2, the product forming operation is achieved. After the upper mold 1 resets, the L-shaped plate 18 resets again, realizing the effect of positioning the raw material plate by this device, preventing misalignment or offset when the operator places the raw material plate, and preventing the quality of the finished product from being affected.

[0042] It should be noted that both telescopic rod 16 and telescopic rod 21 are hydraulically driven, which facilitates the lifting and lowering of the upper mold 1 and the mounting block 8. Through a single lifting of telescopic rod 16, the molding and demolding operations can be integrated.

[0043] The working principle of the above embodiments is as follows:

[0044] First, the operator places the raw material plate on the lower mold 2 and positions it using the L-shaped plate 18. Then, the telescopic rod 11 is activated to lower the upper mold 1. At this time, the pressure plate 13 contacts the L-shaped plate 18, causing the L-shaped plate 18 to descend until it contacts the surface of the lower mold 2. The pressure plate 13 presses and limits the raw material plate. The telescopic rod 11 continues to lower the upper mold 1 until it matches the lower mold 2, completing the edge forming of the raw material plate. Then, the telescopic rod 6 is activated to slide the mounting block 8 on the surface of the limiting rod 7, causing the mounting block 8 to raise the top block 9 and the top block 10 until the upper surface of the raw material plate is flush with the upper mold 1. The groove on the bottom surface is adapted to form the middle position of the raw material plate through the top block 9 and the top block 10. Then, the telescopic rod 11 drives the upper mold 1 to reset. At the same time, the telescopic rod 6 continues to rise, so that the mounting block 8, the top block 9 and the top block 10 can push out the formed rotating disk. This device can complete the forming and demolding operation with one lifting of the telescopic rod 6, which makes it convenient for operators to take out the finished product and improves production efficiency. When the upper mold 1 resets, the L-shaped plate 18 resets under the action of the spring 19, which can complete the positioning and placement of the next raw material plate and prevent the operator from misaligning or shifting the raw material plate, thus preventing the quality of the finished product from being affected.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
