Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a stamping die for a player shield that is easy to replace. Background Technology

[0002] In electronic device manufacturing, media players, as common consumer electronics products, receive widespread attention for their performance and quality. Among these components, the media player shielding is a crucial element protecting the internal electronic components from external electromagnetic interference, ensuring stable signal transmission, and improving the overall reliability of the device. The stamping die, as the core process equipment for manufacturing media player shielding, directly determines the production quality and cost of the shielding through its performance and efficiency.

[0003] Currently, there is a prominent problem with the existing player shielding cover stamping molds in actual production applications. After the stamping process is completed, due to material deformation during the stamping process and the characteristics of the mold structure, the player shielding cover formed after molding often gets tightly stuck in the mold cavity, making it difficult to automatically and smoothly demold. This phenomenon has caused great trouble to the production process.

[0004] Traditional solutions rely primarily on manual disassembly. Workers need to carefully remove the stuck shielding cover from the mold using various tools such as pry bars and pliers. This manual disassembly method is not only inefficient, severely impacting the overall production line's pace and extending the production cycle, thus failing to meet the demands of large-scale, high-efficiency modern production, but also prone to damage during disassembly due to limited operating space and tool limitations. Slight carelessness can cause scratches, deformation, or other damage to the shielding cover, affecting the product's appearance quality and dimensional accuracy, leading to a decrease in product qualification rate and increased production costs.

[0005] Therefore, this utility model provides a stamping mold for easily replacing the ejected player shield cover to solve the above problems. Utility Model Content

[0020] 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.

[0021] This utility model provides a stamping die for easily replacing the ejected player shielding cover, such as... Figures 1-5As shown, the device includes a base 1, with support columns 11 fixedly installed at both ends, and a top seat 12 fixedly installed at the top of each support column 11. Two sets of slide rails 2 are fixedly installed at the top of the base 1, and a mold plate 4 is slidably mounted on the two sets of slide rails 2. The slide rails 2 provide precise guidance for the movement of the mold plate 4, enabling the mold plate 4 to move smoothly along a predetermined straight trajectory, reducing friction and resistance during movement, and improving the stability and accuracy of the movement of the mold plate 4. The outer surface of the mold plate 4 has multiple sets of stamping grooves 41, which can simultaneously stamp multiple plates according to different production needs, greatly improving production efficiency. Lifting devices are slidably installed on the inner walls of the multiple sets of stamping grooves 41. The lifting rod 5 can eject the formed product from the stamping groove 41 after stamping, realizing automatic demolding of the product, avoiding the tediousness and inconvenience of manual part removal, improving production efficiency, and reducing damage to the product caused by manual operation, thus ensuring the appearance quality of the product. Multiple sets of top plates 7 are fixedly installed on one side of the base 1, and the top of the multiple sets of top plates 7 are V-shaped, which are used to lift the corresponding lifting rod 5 during the movement of the mold plate 4 to eject the stamped shield. The base 1 is provided with a pushing component for pushing the mold plate 4. The bottom end of the mold plate 4 is provided with a telescopic component for controlling the up and down extension and retraction of the lifting rod 5. The top end of the top seat 12 is provided with a stamping component for stamping the material plate.

[0022] The pushing component includes a limiting plate 6 fixedly installed on the base 1, and a first cylinder 3 is fixedly installed on the limiting plate 6. A connecting component is fixedly installed on the output shaft of the first cylinder 3, and the connecting component is fixedly connected to the bottom end of the mold plate 4. The first cylinder 3 can accurately control the moving distance and speed of the mold plate 4, while the limiting plate 6 plays the role of fixing and limiting the first cylinder 3, ensuring the stability of the first cylinder 3 during operation, so that the mold plate 4 can accurately move to the stamping position and the demolding position, thereby improving the automation level and production efficiency of production.

[0023] The connecting assembly includes a connecting plate 31 fixedly connected to the output shaft of the first cylinder 3, and two sets of long rods 32 are fixedly installed on the outer surface of the connecting plate 31. The two sets of long rods 32 can distribute the force and make the power transmission more uniform. The ends of the two sets of long rods 32 are provided with connecting plates 33, and the top of the connecting plate 33 is fixedly connected to the bottom of the mold plate 4. The connecting plate 33 further transmits the power of the long rods 32 to the mold plate 4, ensuring the stability of the mold plate 4 during the movement.

[0024] The telescopic assembly includes multiple sets of connecting rings 8 fixedly installed at the bottom of the mold plate 4. Each set of connecting rings 8 has a spring 81 fixedly connected to its bottom end. The elasticity of the spring 81 enables the lifting rod 5 to extend and retract vertically. The end of the spring 81 is fixedly connected to a positioning plate 82, and the top of the positioning plate 82 is fixedly connected to the lifting rod 5. When the top plate 7 lifts the positioning plate 82, the spring 81 is compressed, and the lifting rod 5 pushes the product upward. When the top plate 7 leaves, the spring 81 returns to its original state, and the lifting rod 5 falls back.

[0025] The bottom end of the positioning plate 82 is rotatably mounted with a rotating wheel 83. The rotating wheel 83 can roll when it comes into contact with the top plate 7, which transforms sliding friction into rolling friction, greatly reducing friction and making the lifting process smoother.

[0026] The stamping assembly includes a second cylinder 13 fixedly mounted on the top seat 12, and a fixing plate 14 fixedly mounted on the output shaft of the second cylinder 13. Multiple sets of stamping blocks 15 are fixedly mounted on the bottom end of the fixing plate 14. The second cylinder 13 can provide strong stamping force, so that the stamping blocks 15 can accurately stamp the material plate.

[0027] Multiple sets of limiting rods 21 are fixedly installed between the top seat 12 and the base 1. The multiple sets of limiting rods 21 penetrate the outer surface of the fixing plate 14. The limiting rods 21 provide precise guidance for the up and down movement of the fixing plate 14, ensuring that the stamping block 15 can move vertically downward during the stamping process, thereby improving the accuracy and stability of the stamping.

[0028] The two sets of long rods 32 are fixedly connected to the connecting plate 33 by nuts 42. The connection method of nuts 42 is convenient for disassembly and installation. When it is necessary to repair, replace or adjust the connecting components, nuts 42 can be loosened to separate the long rods 32 from the connecting plate 33, which improves the maintainability and flexibility of the equipment and reduces maintenance time and cost.

[0029] A limiting frame 43 is fixedly installed at the top of the mold plate 4. The material plate needs to be accurately placed above the stamping groove 41 of the mold plate 4 to ensure the stamping quality. The limiting frame 43 provides a clear boundary and placement position for the material plate, allowing workers to quickly and accurately place the material plate into the limiting frame 43, so that the material plate is precisely aligned with the stamping groove 41.

[0030] The outer surface of the rotating wheel 83 is covered with rubber. Rubber has good flexibility and elasticity. Covering the outer surface of the rotating wheel 83 can transform sliding friction into a combination of rolling friction and rubber elastic deformation, which greatly reduces the friction between the rotating wheel 83 and the top plate 7.

[0031] Working principle: In actual production operation, the material plate to be processed is first accurately placed in the stamping groove 41 on the mold plate 4. At this time, the limiting frame 43 at the top of the mold plate 4 can effectively prevent the material plate from shifting during the placement process. After the material plate is placed, the first cylinder 3 in the push assembly is started. The output shaft of the first cylinder 3 retracts, which drives the connecting plate 31 fixedly connected to it to move backward synchronously. The two sets of long rods 32 fixedly installed on the connecting plate 31 also move backward. The long rods 32 are firmly connected to the connecting plate 33 through the nut 42, which in turn drives the connecting plate 33 and the mold plate 4 fixedly connected to the top of the connecting plate 33 to move backward together until the mold plate 4 moves directly under the stamping assembly, so that the stamping groove 41 is accurately in the stamping position. Next, the second cylinder 13 in the stamping assembly is activated. The output shaft of the second cylinder 13 extends downward, pushing the fixed plate 14 fixed on its output shaft to descend smoothly along multiple sets of limit rods 21. The multiple sets of limit rods 21 penetrate the outer surface of the fixed plate 14, providing precise guidance for the vertical movement of the fixed plate 14 and ensuring the accuracy of its movement trajectory. The multiple sets of stamping blocks 15 fixedly installed at the bottom of the fixed plate 14 descend accordingly and precisely stamp the material plate in the multiple sets of stamping grooves 41. During the stamping process, the pressure applied by the stamping blocks 15 causes the material plate to undergo plastic deformation according to the shape of the stamping grooves 41, thereby forming the required shape of the player shield. After the stamping process is completed, the first cylinder 3 is restarted to extend its output shaft forward. Under the push of the first cylinder 3, the connecting plate 31, the long rod 32, the connecting plate 33 and the mold plate 4 move forward together. During the forward movement of the mold plate 4, the rotating wheel 83 in the telescopic assembly at the bottom of the mold plate 4 will contact the multiple sets of top plates 7 fixedly installed on one side of the base 1. Since the top of the top plate 7 is V-shaped, as the mold plate 4 continues to move, the rotating wheel 83 will roll up along the inclined surface at the top of the top plate 7. When the rotating wheel 83 rises, it drives the positioning plate 82, which is rotatably connected to it, to move upward. The positioning plate 82 is connected to multiple sets of connecting rings 8 fixedly installed at the bottom of the mold plate 4 via spring 81. During the rising process of the positioning plate 82, the spring 81 is compressed. At the same time, the lifting rod 5 fixedly connected to the top of the positioning plate 82 moves upward with the positioning plate 82. The lifting rod 5 slides upward in the stamping groove 41, lifting the formed shielding cover that is pressed in the stamping groove 41 out, realizing the automatic demolding of the shielding cover, avoiding the tediousness and inconvenience of manual disassembly, and greatly improving production efficiency.

[0032] As the mold plate 4 continues to move forward, after the rotating wheel 83 leaves the top plate 7, under the elastic restoring force of the spring 81, the positioning plate 82 and the lifting rod 5 will fall back to their initial positions, preparing for the next stamping process.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
