Description

Technical Field

[0001] This utility model belongs to the technical field of stamping dies, specifically relating to a stamping die for riveting parts of laptop computers. Background Technology

[0002] A stamping die for laptop riveting parts is a special die used to produce riveting parts for laptops. Laptop riveting parts consist of two parts: a hinge fixing bracket and a hinge opening / closing bracket. These are the structures used for opening and closing the laptop. The stamping die applies pressure to the metal sheet using a press, causing it to plastically deform or separate within the die, thus forming the desired riveting part shape. This type of die requires high-precision design and manufacturing to meet the miniaturization, lightweight, and high strength requirements of laptops. The choice of die material, structural design, and processing technology directly affect the quality and production efficiency of the riveting parts. In laptop manufacturing, the application of stamping dies enables the mass production of riveting parts with high consistency, meeting the needs of electronic devices for precision components.

[0003] However, when existing stamping equipment stamps metal sheets, the pressure applied instantaneously by the upper die causes one end of the metal sheet to warp up, making the metal sheet not flat enough during stamping. This affects the stamping accuracy of the riveted parts and cannot meet the high precision requirements of laptops for riveted parts. Utility Model Content

[0004] The purpose of this utility model is to provide a stamping die for riveting parts of laptop computers, so as to solve the problem mentioned in the background art that when the existing stamping device stamps metal sheets, the pressure applied by the upper die at the moment causes one end of the metal sheet to curl up, making the metal sheet not flat enough during stamping, affecting the stamping accuracy of the riveting parts, and failing to meet the high precision requirements of laptop computers for riveting parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamping die for a laptop computer riveting part, comprising a top plate and an upper die disposed at the bottom of the top plate; The top plate has sleeve rods at its four bottom corners, the upper mold has a lower mold below it, the lower mold has a base plate at its bottom, and the base plate has inner rods at its four top corners. The lower mold is provided with multiple pairs of pressure blocks, each pressure block having a mating groove and a pressure plate. The lower mold is provided with a sliding cavity, inside which is a bottom spring. Slider blocks are provided on both sides of the sliding cavity. Sliding grooves are provided on both sides of the pressure block. The upper mold is also provided with a sliding cavity, inside which is a push rod. The push rod has a cavity inside, and a sliding rod is provided inside the sliding cavity. A top spring is provided on the outside of the sliding rod.

[0006] Preferably, the pressure block is inserted into the lower mold, the pressure block can slide into the sliding cavity, the slider is welded to the lower mold, and the slider is slidably connected to the slide groove.

[0007] Preferably, the bottom spring is welded to the pressure block and the lower mold respectively. The pressure block can compress the bottom spring by moving downward, and the bottom spring can push the pressure block upward to reset.

[0008] Preferably, the pressure plate and the pressure block are integrally formed, the pressure plate can hold the riveted parts, and the bottom of the pressure plate is provided with an anti-slip pad, which is adhered and fixed to the pressure plate.

[0009] Preferably, a gasket is provided inside the docking groove, and the gasket is adhered and fixed to the pressure block. The gasket can buffer the top rod.

[0010] Preferably, the ejector rod is inserted into the sliding cavity on the upper mold, and the ejector rod can slide into the sliding cavity. The slide rod is welded to the upper mold, and the slide rod is inserted into the ejector rod, and the slide rod can slide into the cavity.

[0011] Preferably, the top spring is sleeved with the slide rod, the bottom of the slide rod is provided with a baffle, the baffle and the slide rod are integrally formed, the top rod is provided with a limit block, the limit block and the top rod are integrally formed, and the limit block can block the baffle.

[0012] Compared with the prior art, this utility model provides a stamping die for riveting parts of laptop computers, which has the following advantages: 1. Through the arrangement of pressure blocks, pressure plates, bottom springs, docking grooves, ejector pins, slide bars, top springs, and sliding cavities, this stamping mechanism achieves stable pressing of the metal sheet when the upper mold moves downward. After the ejector pin docks with the pressure block, it pushes the pressure plate to firmly fix both ends of the sheet, effectively preventing unilateral warping and ensuring that the sheet remains flat during the stamping process, thereby improving the forming accuracy of the riveted parts. The ejector pin continues to slide into the sliding cavity and compresses the top spring, while the slide bar retracts synchronously. After the stamping is completed, the elastic restoring force of the bottom spring pushes the pressure block to reset, and the top spring drives the ejector pin to return to its position, realizing an efficient and continuous stamping operation cycle.

[0013] 2. By setting up limit blocks, baffles, sliders, and slide grooves, the stability and accuracy of the mechanism operation are further improved. Limit blocks, baffles, sliders, and slide grooves are added. The slide rod ensures that the ejector rod slides smoothly in the vertical direction. The baffle and limit block cooperate to prevent the ejector rod from disengaging from the upper mold. The cooperation between the slider and the slide groove ensures that the pressure block moves vertically, so that the pressure block and the ejector rod are accurately connected, avoiding offset or jamming, and improving the reliability and durability of the overall mechanism.

[0014] 3. By setting shims and anti-slip pads, the addition of buffer shims and anti-slip pads further optimizes the stamping performance. Buffer shims effectively absorb the impact force when the push rod contacts the pressure block, reduce component wear, and extend service life. Anti-slip pads enhance the friction between the pressure plate and the metal sheet, prevent the sheet from sliding during the stamping process, ensure accurate forming dimensions, and make the entire stamping system efficient, stable, and precise.

[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, for example Figure 1-4 The illustrated notebook computer riveting stamping die includes a top plate 1 and an upper die 2 disposed at the bottom of the top plate 1; The top plate 1 has sleeve rods 3 at its four bottom corners, the upper mold 2 has a lower mold 8 below it, the lower mold 8 has a base plate 5 at its bottom, and the base plate 5 has inner rods 4 at its four top corners. The lower mold 8 is provided with multiple pairs of pressure blocks 7, each with a mating groove 13 and a pressure plate 9. The lower mold 8 is provided with a sliding cavity 21, inside which is a bottom spring 18. Slider blocks 12 are provided on both sides of the sliding cavity 21. Sliding grooves 11 are provided on both sides of the pressure blocks 7. The upper mold 2 is also provided with a sliding cavity 21, inside which is a push rod 6. Inside the push rod 6 is a cavity 17. Inside the sliding cavity 21 is a slide rod 15, and outside the slide rod 15 is a top spring 16.

[0022] In this embodiment, the working principle of the notebook computer riveting stamping die is to use the power of the press to squeeze, shear, or stretch the metal sheet between the upper die 2 and the lower die 8, thereby forming a riveting part of a specific shape. The method of using the stamping die is as follows: the operator first feeds the metal sheet into the area between the upper die 2 and the lower die 8, and then starts the press to stamp. When the upper die 2 moves downward, it can be guided by the cooperation of the sleeve rod 3 and the inner rod 4. After stamping, the formed riveting part may be automatically ejected by the ejector device or removed manually. The upper die 2 and the lower die 8 need to be maintained regularly to check the wear of the cutting edges and lubricate the moving parts to ensure stamping accuracy and extend the die life. Since notebook computer riveting parts are usually small in size and high in precision, the manufacturing and debugging of the die must be very precise to ensure that the stamped parts meet strict tolerance requirements for subsequent assembly and use.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the pressure block 7 is inserted into the lower mold 8, and the pressure block 7 can slide into the sliding cavity 21. The slider 12 is welded to the lower mold 8 and is slidably connected to the slide groove 11. The bottom spring 18 is welded to the pressure block 7 and the lower mold 8 respectively. The pressure block 7 can compress the bottom spring 18 when it moves downward, and the bottom spring 18 can push the pressure block 7 upward to reset. The pressure plate 9 is integrally formed with the pressure block 7. The pressure plate 9 can hold the riveted parts. The bottom of the pressure plate 9 is provided with an anti-slip pad 10, which is bonded and fixed to the pressure plate 9. The mating groove 13 is provided with a gasket 14, which is bonded and fixed to the pressure block 7. The gasket 14 can buffer the push rod 6.

[0024] Preferably, with the arrangement of pressure block 7, pressure plate 9, bottom spring 18, docking groove 13, ejector rod 6, slide rod 15, top spring 16 and sliding cavity 21, when the upper mold 2 moves down, ejector rod 6 will contact pressure block 7 and then insert into docking groove 13 on pressure block 7. After that, ejector rod 6 will push pressure block 7 down, thereby driving pressure plate 9 to press and fix both ends of metal sheet respectively, preventing one end of metal sheet from being pushed up by force, ensuring that metal sheet remains flat during stamping, and ensuring stamping accuracy of riveted parts. At this time, ejector rod 6 will continue to slide into sliding cavity 21 above, thereby compressing top spring 16. At the same time, slide rod 15 slides into cavity 17 inside ejector rod 6. When stamping is completed and upper mold 2 moves up, the compressed bottom spring 18 will return to its original position due to the recovery of elasticity, thereby pushing pressure block 7 above back up and resetting. Ejector rod 6 is pushed back to its original position by top spring 16, which facilitates subsequent stamping work.

[0025] like Figure 3 and Figure 4 As shown, the ejector rod 6 is inserted into the sliding cavity 21 on the upper mold 2, and the ejector rod 6 can slide into the sliding cavity 21. The slide rod 15 is welded to the upper mold 2 and inserted into the ejector rod 6. The slide rod 15 can slide into the cavity 17. The top spring 16 is sleeved with the slide rod 15. A baffle 20 is provided at the bottom of the slide rod 15. The baffle 20 and the slide rod 15 are integrally formed. A limit block 19 is provided on the ejector rod 6. The limit block 19 and the ejector rod 6 are integrally formed. The limit block 19 can block the baffle 20.

[0026] Preferably, by setting the limiting block 19, baffle 20, slider 12 and slide groove 11, the slide rod 15 can ensure the vertical sliding of the ejector rod 6. The cooperation between the baffle 20 and the limiting block 19 can limit the position of the ejector rod 6 and prevent the ejector rod 6 from disengaging from the upper mold 2. The cooperation between the slider 12 and the slide groove 11 can ensure the vertical sliding of the pressure block 7, so that the pressure block 7 and the ejector rod 6 can be accurately connected.

[0027] Preferably, by setting the shim 14 and the anti-slip pad 10, the shim 14 can reduce the collision between the push rod 6 and the pressure block 7, ensuring the service life of the pressure block 7 and the push rod 6, and the anti-slip pad 10 can prevent the pressed metal sheet from sliding, ensuring the stamping accuracy of the metal sheet.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
