Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a high-efficiency positioning mold for stamping precision shielding covers. Background Technology
[0002] Stamping is a highly efficient forming process that can produce a large number of precision shielding covers in a short time. Precision shielding covers are miniature metal shells used in electronic devices. They are mainly used to prevent external interference electromagnetic fields and heat energy from diffusing into the shell, thereby achieving the effect of shielding various external electromagnetic and heat sources. They are widely used in products such as mobile phones, tablets, laptops, and headphones to shield electromagnetic waves generated by internal circuits, preventing them from interfering with other components. They also prevent external electromagnetic waves from interfering with internal circuits, thereby improving the performance and stability of the products.
[0003] Traditional positioning dies used in precision shielding cover stamping require multiple tools and complex steps for replacement, resulting in lengthy replacement times and numerous shortcomings in practical use. For example, some traditional dies use bolt fastening for positioning and installation. Replacement requires unscrewing multiple bolts one by one with a wrench. Due to the large number and dense distribution of bolts and the narrow operating space, not only is the tightening process physically demanding, but it also easily leads to stripped bolts and lost nuts that are difficult to find. In addition, some dies use permanent connections such as welding or riveting to the main structure for positioning components. Replacement requires disassembly using cutting and grinding tools, which not only generates a large amount of metal shavings, polluting the working environment, but also easily damages other parts of the die, further increasing maintenance costs. These factors significantly reduce the efficiency of stamping precision shielding covers, making it difficult to meet the high-efficiency production requirements of modern manufacturing.

[0023] 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.
[0024] Example 1: Please refer to Figure 1-6 This utility model provides a technical solution: a high-efficiency positioning mold for precision shielding cover stamping, including a machine body 1, a fixing block 11 fixedly installed in the middle of the upper end of the machine body 1, a drive motor 21 fixedly installed in the middle of the fixing block 11, a turntable 22 fixedly installed at the output end of the drive motor 21, a plurality of placement slots 23 evenly opened around the outer perimeter of the turntable 22, fixing plates 27 fixedly installed on both sides of the middle of the middle of the plurality of placement slots 23, a slot 28 opened in the middle of the middle of the fixing plates 27, a stamping mold 24 being snapped into the middle of the plurality of placement slots 23, a clamping plate 25 fixedly installed in the middle of the middle of both ends of the plurality of stamping molds 24, a cross slot 26 opened on one side of the clamping plate 25 of each stamping mold 24, wherein one of the fixing plates in each group of fixing plates 27 Each of the two plates 27 has a sliding groove 29 in the middle. A spring 30 is fixedly installed at one end of the sliding groove 29, and a slide plate 31 is fixedly installed at one end of the spring 30. A groove 34 is opened in the middle of the slide plate 31, and a cross-shaped insert rod 33 is fixedly installed at one end of the groove 34. The clamping plates 25 on both sides of the stamping die 24 are respectively engaged with the corresponding clamping slots 28 opened in the middle of the fixed plate 27. The clamping slot 28 in the middle of one of the fixed plates 27 is connected to the sliding groove 29. The slide plate 31 is slidably engaged in the middle of the sliding groove 29. The opening area of the groove 34 is larger than the volume of the clamping plate 25. A pressing rod 32 is fixedly installed through the fixed plate 27 at one end of the slide plate 31. The stamping die 24 is engaged by the cross-shaped insert rod 33 opened on one side of the clamping plate 25 and the cross-shaped insert rod 33 installed on the slide plate 31.
[0025] In this embodiment, the body 1 is the foundation of the overall structure. The upper fixing block 11 serves to support and fix the drive motor 21. The output end of the drive motor 21 is fixedly connected to the turntable 22, which can drive the turntable 22 to rotate and realize the sequential stamping of multiple stamping dies 24. Multiple placement slots 23 are evenly distributed around the outer perimeter of the turntable 22 for placing the stamping dies 24. Fixing plates 27 are fixedly installed on both sides of the middle of each placement slot 23. The fixing plates 27 have slots 28 for engaging with the locking plates 25 at both ends of the stamping die 24. When installing the stamping die 24, the stamping die 24 is placed in the corresponding placement slot 23, so that the locking plates 25 at both ends of the stamping die 24 are aligned with the slots 28 on the fixing plates 27 on both sides of the placement slot 23. The stamping die 24 is pushed down to make the locking plates 25 engage with the slots 28. Then, the pressing rod 32 is pressed to make the slide plate 31 slide. The slide 31 slides within the groove 29, at which point the spring 30 is compressed. Releasing the press allows the cross-shaped insert 33 on the slide plate 31 to insert into the cross-shaped slot 26 of the clamping plate 25 on one side of the stamping die 24, thus fixing and positioning the stamping die 24. After the stamping die 24 has been used for a period of time, the internal positioning pins, positioning blocks, and other parts that frequently come into contact with the raw materials are prone to wear, leading to a decrease in positioning accuracy. Therefore, they need to be replaced. When replacing, simply press the corresponding pressing rod 32 again, and the slide plate 31 slides within the sliding groove 29. The spring 30 is compressed accordingly, and the cross-shaped insert 33 will disengage from the cross-shaped slot 26 of the clamping plate 25 on one side of the stamping die 24. Then, pull the stamping die 24 upward to disassemble it. Repeat the installation process. By achieving rapid installation and precise positioning of the stamping die 24, the stamping quality and production efficiency of the shielding cover can be greatly improved.
[0026] Example 2: Figure 1-3 As shown, a bracket 13 is fixedly installed on one side of the upper middle part of the machine body 1. A hydraulic cylinder 14 is fixedly installed on the upper end of the bracket 13. A punch head 15 is fixedly installed on the output end of the hydraulic cylinder 14. A horizontal angle adjustment motor 16 is fixedly installed on one side of the upper end of the bracket 13. A cylinder 17 is fixedly installed on one end of the horizontal angle adjustment motor 16. A suction cup 18 is fixedly installed on one end of the cylinder 17. An inclined hopper 19 is fixedly installed on one end of the upper middle part of the machine body 1.
[0027] In this embodiment, the hydraulic cylinder 14, the horizontal angle adjustment motor 16, and the hydraulic cylinder 14 and the stamping head 15 are combined by the bracket 13, which can realize multiple functions such as feeding, stamping, and picking up parts, thereby improving the continuity and automation of production. The hydraulic cylinder 14 drives the stamping head 15 to stamp and form the raw material in the stamping die 24. The combination of the horizontal angle adjustment motor 16, the cylinder 17, and the suction cup 18 can move the stamped precision shield to the inclined hopper 19 for unloading. The inclined hopper 19 uses gravity to realize the automatic downward conveying of materials without the need for additional power drive.
[0028] like Figure 1-6 As shown, during production, the worker places the raw material to be stamped into the stamping die 24 in sequence, and then the drive motor 21 starts working. The drive motor 21 drives the turntable 22 to rotate. Multiple stamping dies 24 are installed on the turntable 22, which can realize the sequential switching of dies. When the stamping die 24 containing the raw material rotates to directly below the stamping head 15, stamping can be performed. The hydraulic cylinder 14 drives the stamping head 15 to move downward, applying pressure to the raw material in the stamping die 24. During the process, the raw material will undergo plastic deformation in the die according to the designed shape and size, thereby completing the stamping. After the stamping is completed, the turntable 22 continues to rotate and will rotate the stamped die to the suction cup. Below 18, the horizontal angle adjustment motor 16 adjusts the angle of the suction cup 18 to align it with the stamped precision shield. The cylinder 17 extends to bring the suction cup 18 closer to the finished product. After the suction cup 18 is powered on to pick up the finished product, the cylinder 17 retracts to lift the finished product and move it to the inclined hopper 19 for unloading. Utilizing the inclined structure of the inclined hopper 19, the finished product slides down the inclined hopper 19 under gravity to the collection area, realizing the automatic output of the finished product. With the continuous use of the stamping die 24, the internal positioning pins, positioning blocks and other components wear due to frequent contact with the raw materials, and the positioning accuracy will decrease. Therefore, they need to be replaced in time. During replacement, press the pressing rod 32 corresponding to the mold to be replaced. During the process, the sliding plate 31 will slide in the sliding groove 29, while the spring 30 is in a compressed state. At this time, the cross-shaped insert 33 will disengage from the cross slot 26 of the clamping plate 25 on one side of the stamping mold 24. Pull the stamping mold 24 upward to remove it. Then, place the new stamping mold 24 in the corresponding placement groove 23, align the clamping plates 25 at both ends of the stamping mold 24 with the slots 28 on the fixing plates 27 on both sides of the placement groove 23, and push the stamping mold 24 downward. 4. Due to the presence of the sliding plate 31, the new stamping die 24 cannot reach the bottom. The pressing rod 32 can be squeezed again to make the sliding plate 31 slide in the sliding groove 29, so that the spring 30 is in a compressed state, so that the sliding plate 31 will not block the stamping die 24. The stamping die 24 can then be pressed down until it reaches the bottom. Then the pressing rod 32 is released and the spring 30 returns to its deformation, pushing the sliding plate 31 to reset so that the cross-shaped insert rod 33 is inserted into the cross-shaped slot 26 of the clamping plate 25 on one side of the stamping die 24, thereby realizing the installation of the new stamping die 24.
