Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and more specifically, to a pop-up sensor sheet punching mold. Background Technology

[0002] Pop-up sensors are widely used in many fields such as electronic devices and smart homes. Drilling is one of the key processes in their production. Generally, the material of the sensor sheet is punched out by using the huge pressure generated by equipment such as a punch press through a mold. The mold has a punch and a die that match the shape and size of the required hole. When the punch descends, the material is cut off under pressure to form a hole.

[0003] When processing pop-up sensor sheets using traditional punching dies, the sensor sheet needs to be removed using rigid ejection or manual assistance after punching. This can easily lead to uneven stress on the sensor sheet, resulting in deformation, surface scratches, and other problems. This not only increases the labor intensity of workers but also easily damages the sensor sheet, affecting product quality. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a pop-up sensor sheet punching mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A pop-up sensor sheet punching mold includes an upper mold base and a lower mold base. The upper mold base is located on top of the lower mold base. T-shaped guide plates are fixedly provided on both sides of the lower mold base. Guide frames are fixedly provided on both sides of the upper mold base. The T-shaped guide plates and guide frames are slidably connected. An unloading mechanism is provided inside the lower mold base. The unloading mechanism includes a through hole on the surface of the lower mold base, a fixing plate is fixedly installed on one side of the through hole, a guide cylinder is fixedly installed on the top of the fixing plate, a guide rod is slidably installed inside the guide cylinder, an arc-shaped top is fixedly installed on the top of the guide rod, a spring is fixedly installed between the arc-shaped top and the through hole, and a collection box is fixedly installed at the bottom of the through hole. The arc-shaped top can be made of rubber, and the spring sleeve is disposed outside the guide cylinder and the guide rod.

[0006] By adopting the above technical solution: the rubber arc-shaped top head cooperates with the spring to store energy during drilling and smoothly push out the induction plate during unloading, avoiding damage and ensuring product quality. Moreover, the guiding structure of the guide cylinder and guide rod ensures stable and accurate unloading action and improves unloading reliability.

[0007] As a further description of the above technical solution: the lower mold base is provided with a positioning mechanism, the positioning mechanism includes a plurality of small electric telescopic rods fixedly installed on the inner wall of the lower mold base, the output end of the small electric telescopic rods is fixedly provided with a positioning plate, and guide blocks are fixedly provided on both sides of the positioning plate. The inner wall of the lower mold base is provided with a sliding groove, and the guide block is slidably connected to the sliding groove.

[0008] By adopting the above technical solution, the induction sheet can be accurately positioned, effectively reducing manual positioning errors, improving drilling accuracy and product qualification rate. Moreover, the structure is stable and reliable, and the operation is smooth and without shaking, reducing mold wear caused by unstable positioning and extending the service life of the equipment.

[0009] As a further description of the above technical solution: a connecting mold handle is fixedly provided on the top of the upper mold base, a pad is fixedly provided on the bottom of the upper mold base, and a plurality of punch heads are fixedly provided on the bottom of the pad. A connecting frame is provided through the bottom of the lower mold base, one end of the connecting frame is connected to the collection box, and a collection drawer is inserted into the inside of the collection box.

[0010] By adopting the above technical solutions: connecting the mold handle facilitates a quick and stable connection between the upper mold base and the stamping equipment, ensures stable power transmission during the punching process, improves the efficiency of mold installation and disassembly, enables automatic collection of waste materials, facilitates centralized cleaning, maintains a clean working environment, ensures production continuity, and reduces maintenance costs.

[0011] The technical effects and advantages of this utility model are as follows: 1. By setting up an unloading mechanism, compared with the existing technology, the spring and the arc-shaped top work together. When drilling, the spring is compressed and stores energy. The rubber arc-shaped top can not only buffer the pressure and ensure that the sensing plate is not damaged, but also help to fix the sensing plate and improve the drilling accuracy. After drilling, the spring returns to its deformation and pushes the arc-shaped top to smoothly lift the sensing plate. The unloading process is gentle and impact-free, avoiding deformation or surface scratches of the sensing plate and ensuring product quality. At the same time, the waste material falls automatically into the collection drawer through the through hole and the connecting frame, which is convenient for centralized cleaning, keeps the working environment clean, ensures production continuity, and reduces maintenance costs. 2. By setting up a positioning mechanism, compared with existing technologies, the small electric telescopic rod, after being connected to an external power source, drives the positioning plate to slide smoothly along the slide groove. With the tight sliding cooperation between the guide blocks on both sides and the slide groove, it achieves millimeter-level precise positioning of the induction sheet, effectively avoiding drilling position errors caused by manual positioning deviations, and significantly improving the product qualification rate. At the same time, the positioning process is stable and without shaking. Even when facing induction sheets of different specifications, it can be flexibly adapted by adjusting the telescopic rod's extension amount, enhancing the mold's versatility. In addition, the mechanism operates reliably, reducing mold wear and equipment failures caused by unstable positioning, lowering maintenance costs, and ensuring production continuity and stability.

[0018] 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.

[0019] The embodiments disclosed in this application are as follows: Figure 1-5The pop-up sensor punch mold shown includes an upper mold base 1 and a lower mold base 2. The upper mold base 1 is set on the top of the lower mold base 2. T-shaped guide plates 3 are fixedly set on both sides of the lower mold base 2. Guide frames 4 are fixedly set on both sides of the upper mold base 1. The T-shaped guide plates 3 and guide frames 4 are slidably connected. The lower mold base 2 is equipped with an unloading mechanism inside. The unloading mechanism includes a through hole 5 on the surface of the lower mold base 2, a fixing plate 6 fixedly installed on one side of the through hole 5, a guide cylinder 7 fixedly installed on the top of the fixing plate 6, a guide rod 8 slidably installed inside the guide cylinder 7, an arc-shaped top 9 fixedly installed on the top of the guide rod 8, a spring 10 fixedly installed between the arc-shaped top 9 and the through hole 5, and a collection box 11 fixedly installed at the bottom of the through hole 5. The arc-shaped top 9 can be made of rubber, and the spring 10 is fitted on the outside of the guide cylinder 7 and the guide rod 8; The pad 16 and multiple punch heads 17 at the bottom of the upper die holder 1 descend accordingly. When the punch head 17 contacts the pre-positioned sensing plate, under continuous pressure, the arc-shaped top head 9, after being pressured by the sensing plate, drives the guide rod 8 to slide downward in the guide cylinder 7, causing the spring 10 sleeved on the outside of the guide cylinder 7 and the guide rod 8 to be compressed. During the compression process, the spring 10 stores elastic potential energy, providing power for the subsequent unloading action. At this stage, due to the compression of the spring 10, the arc-shaped top head 9 is in close contact with the sensing plate. At the same time, because the arc-shaped top head 9 can be made of rubber, it has a certain buffering effect, which will not damage the sensing plate and ensure that the sensing plate remains stable during the punching process. The punch head 17 punches the sensing plate to complete the processing step.

[0020] Reference Figure 2-4 As shown, the lower mold base 2 is provided with a positioning mechanism. The positioning mechanism includes multiple small electric telescopic rods 12 fixedly installed on the inner wall of the lower mold base 2. The output end of the small electric telescopic rods 12 is fixedly provided with a positioning plate 13. Guide blocks 14 are fixedly installed on both sides of the positioning plate 13. The inner wall of the lower mold base 2 is provided with a sliding groove, and the guide block 14 is slidably connected to the sliding groove; Place the pop-up sensor sheet that needs to be punched on the lower mold base 2, use the positioning mechanism inside the lower mold base 2 to position the sensor sheet, connect the small electric telescopic rod 12 to the external power supply, start the small electric telescopic rod 12, and the output end of the small electric telescopic rod 12 drives the positioning plate 13 to move along the slide groove on the inner wall of the lower mold base 2. Meanwhile, the guide blocks 14 on both sides of the positioning plate 13 slide in cooperation with the slide groove. As the positioning plate 13 moves, the guide blocks 14 accurately clamp and position the sensing sheet in the predetermined position, ensuring that the sensing sheet will not be displaced when drilling. Next, a downward pressure is applied to the connecting shank 15 at the top of the upper die holder 1 by a stamping device. Under the action of pressure, the upper die holder 1 moves downward along the sliding track of the T-shaped guide plate 3 and the guide frame 4.

[0021] Reference Figure 3-5 As shown, a connecting mold handle 15 is fixedly provided on the top of the upper mold base 1, a pad 16 is fixedly provided on the bottom of the upper mold base 1, and a plurality of punch heads 17 are fixedly provided on the bottom of the pad 16. A connecting frame 18 is provided through the bottom of the lower mold base 2. One end of the connecting frame 18 is connected to the collection box 11. A collection drawer 19 is inserted into the inside of the collection box 11. Furthermore, the waste generated during the punching process, such as the punched-out pieces, falls downward through the through holes 5 on the surface of the lower die base 2. The waste enters the collection box 11 at the bottom through the connecting frame 18 that is provided through the bottom of the lower die base 2. The collection drawer 19 inserted inside the collection box 11 can be pulled out periodically to clean up the collected waste, keep the working environment of the mold clean, and facilitate subsequent continuous production. After the punching is completed, the stamping equipment releases the pressure on the upper die holder 1, the upper die holder 1 moves upward to reset, and the small electric telescopic rod 12 is activated to retract, thereby driving the positioning plate 13 to reset. This causes the spring 10 to recover its elastic deformation, pushing the arc-shaped top 9 upward. Utilizing the softness of the arc-shaped top 9, the sensing plate is smoothly lifted, causing it to detach from the lower mold base 2, thus achieving unloading.

[0022] Working principle of this utility model: This utility model is a pop-up sensor sheet punching mold. When using this device, the mold is connected and fixed to the stamping equipment through the connecting mold handle 15 on the top of the upper mold base 1. Then, check the installation status of the upper mold base 1 and the lower mold base 2 to ensure that the upper mold base 1 is located on top of the lower mold base 2, and that the T-shaped guide plates 3 on both sides of the lower mold base 2 and the guide frames 4 on both sides of the upper mold base 1 are in the correct sliding connection position, so as to provide stable guidance for the opening and closing movement of the mold. Next, place the pop-up sensor sheet that needs to be punched on the lower mold base 2, use the positioning mechanism inside the lower mold base 2 to position the sensor sheet, connect the small electric telescopic rod 12 to the external power supply, start the small electric telescopic rod 12, and the output end of the small electric telescopic rod 12 drives the positioning plate 13 to move along the slide groove on the inner wall of the lower mold base 2. Meanwhile, the guide blocks 14 on both sides of the positioning plate 13 slide in cooperation with the slide groove. As the positioning plate 13 moves, the guide blocks 14 accurately clamp and position the sensing sheet in the predetermined position, ensuring that the sensing sheet will not be displaced when drilling. Next, a downward pressure is applied to the connecting shank 15 at the top of the upper die holder 1 by a stamping device. Under the action of pressure, the upper die holder 1 moves downward along the sliding track of the T-shaped guide plate 3 and the guide frame 4. The pad 16 and multiple punch heads 17 at the bottom of the upper mold base 1 descend accordingly. When the punch head 17 contacts the pre-positioned sensing sheet, under continuous pressure, the arc-shaped top head 9 is subjected to the pressure of the sensing sheet, which drives the guide rod 8 to slide downward in the guide cylinder 7. This causes the spring 10 sleeved on the outside of the guide cylinder 7 and the guide rod 8 to be compressed. During the compression process, the spring 10 stores elastic potential energy to provide power for the subsequent unloading action. At this stage, due to the compression of the spring 10, the arc-shaped top head 9 is in close contact with the sensing sheet. At the same time, because the arc-shaped top head 9 can be made of rubber, it has a certain buffering effect and will not damage the sensing sheet. It also ensures that the sensing sheet remains stable during the punching process. The punch head 17 punches the sensing sheet to complete the processing step. Furthermore, the waste generated during the punching process, such as the punched-out pieces, falls downward through the through holes 5 on the surface of the lower die base 2. The waste enters the collection box 11 at the bottom through the connecting frame 18 that is provided through the bottom of the lower die base 2. The collection drawer 19 inserted inside the collection box 11 can be pulled out periodically to clean up the collected waste, keep the working environment of the mold clean, and facilitate subsequent continuous production. After the punching is completed, the stamping equipment releases the pressure on the upper die holder 1, the upper die holder 1 moves upward to reset, and the small electric telescopic rod 12 is activated to retract, thereby driving the positioning plate 13 to reset. This causes the spring 10 to recover its elastic deformation, pushing the arc-shaped top 9 upward. Utilizing the softness of the arc-shaped top 9, the sensing plate is smoothly lifted, causing it to detach from the lower mold base 2, thus achieving unloading.

[0023] 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.
