[0002] A high-precision heat spreader stamping die is a type of mold used to manufacture high-precision heat spreaders. A high-precision heat spreader stamping die typically consists of an upper die and a lower die. During operation, the upper die moves downward under the action of a press and closes with the lower die, applying pressure to the heat spreader material placed in the mold cavity, causing it to undergo plastic deformation within the mold cavity, thereby stamping out a heat spreader with a specific shape and size.
[0003] During the stamping process, the punches of the die are prone to wear and damage, requiring timely replacement. These vulnerable parts require high manufacturing precision and have high replacement costs. Existing technologies utilize locating pins, locating holes, or optical locating devices on the die to quickly and accurately determine the position of vulnerable parts within the die, facilitating disassembly and installation. The die design incorporates specialized locating benchmarks, enabling maintenance personnel to quickly locate the vulnerable parts requiring replacement and ensuring accurate installation after replacement.

The left and right sides of the forming box 15 are provided with scraping mechanisms 2 for scraping off the waste residue inside the forming box 15.
[0027] Specifically, hydraulic rods 3 are fixedly connected to the four corners of the top of the base plate 1. When the hydraulic system is started, multiple hydraulic rods 3 can work together to drive the top plate 4 to move smoothly up and down through telescopic movements. The fixed column 5 fixedly connected to the bottom of the top plate 4 will move synchronously with the top plate 4. The positioning pin 6 connected to the bottom of the fixed column 5 is used to accurately position the material to be stamped when the mold is working, ensuring the accuracy of the forming position of the heat spreader. The front side of the fixed column 5 has a slot 7, in which the clamping plate 8 can slide smoothly. During installation, the clamping plate 8 is first inserted into the slot 7, and then two bolts 9 are threaded to the front and rear sides of the top of the clamping plate 8. The bottom of these bolts 9 are threaded to the same extrusion head 10. By tightening the bolts 9, the extrusion head 10 can be fixed to the bottom of the fixed column 5. The bottom of the outer wall of the positioning pin 6 and the front side of the extrusion head 10 are both provided with There is an insertion slot 11, and the retaining strip 12 can slide in the insertion slot 11. In specific operation, the retaining strip 12 is inserted into the insertion slot 11 opened on the front side of the extrusion head 10 and passes through the insertion slot 11 opened on the front side of the positioning pin 6, so as to further stabilize the connection between the positioning pin 6 and the extrusion head 10. Fixing plates 13 are provided on the front and rear sides of the two retaining strips 12. After the fixing plates 13 are aligned with the retaining strips 12, multiple bolts 14 are threaded to the opposite side of the fixing plates 13, and the multiple bolts 14 are threaded to the front and rear sides of the extrusion head 10, thereby fixing the fixing plates 13 to the front and rear sides of the extrusion head 10, ensuring the stability of the entire connection structure. A forming box 15 is fixedly connected to the top of the base plate 1. When the material is accurately positioned, the hydraulic rod 3 pushes the top plate 4 to drive the extrusion head 10 downward, and the stamping and forming operation of the heat-spreading sheet is completed in the forming box 15.
[0028] In another embodiment of this utility model, referring to Figure 5 The scraping mechanism 2 includes multiple fixed sleeves 201. The multiple fixed sleeves 201 are fixedly connected to each other on the left and right sides of the forming box 15. Rotating rods 202 are rotatably connected inside the two left fixed sleeves 201 and the two right fixed sleeves 201. The rotating rods 202 can rotate inside the fixed sleeves 201. Connecting plates 203 are fixedly connected to the top of the outer wall of the two rotating rods 202. Support plates 204 are fixedly connected to the top of the two connecting plates 203. Two telescopic rods 205 are fixedly connected between each adjacent support plate 204. The same scraper 206 is fixedly connected to the right side of the two left telescopic rods 205 and the left side of the two right telescopic rods 205. When it is necessary to scrape off the waste generated inside the forming box 15, the rotating rods 202 are rotated to make the support plates 204 face upward. The telescopic rods 205 push the scraper 206 to move left and right inside the forming box 15 to scrape off the waste inside.
[0029] Specifically, multiple fixed sleeves 201 are fixedly connected to each other on the left and right sides of the forming box 15, providing stable support for the entire cleaning structure. Rotating rods 202 are rotatably connected inside the two fixed sleeves 201 on the left and the two fixed sleeves 201 on the right. The rotating rods 202 can rotate flexibly inside the fixed sleeves 201. A connecting plate 203 is fixedly connected to the top of the outer wall of the rotating rod 202. The connecting plate 203 is then connected to the support plate 204. Two telescopic rods 205 are fixedly connected between the two support plates 204. The right side of the left telescopic rod 205 and the left side of the right telescopic rod 205 are jointly fixedly connected to the scraper 206. When the stamping operation is completed and waste accumulates inside the forming box 15, the operator can rotate the rotating rod 202 to adjust the support plate 204 to the upward position. The telescopic rods 205 are activated, pushing the scraper 206 to move left and right inside the forming box 15, which can effectively scrape off the waste inside the forming box 15. Then the scraped waste inside the forming box 15 is removed to ensure the cleanliness of the inside of the forming box 15.
[0030] Reference Figure 1 , Figure 2 and Figure 3 Support columns 16 are fixedly connected to the four corners of the bottom of the base plate 1. Anti-slip sleeves 17 are fixedly connected to the bottom of the multiple support columns 16 to increase the friction with the ground and prevent movement. Light holders 18 are fixedly connected to the left and right sides of the bottom of the top plate 4. Lighting lamps 19 are fixedly connected to the bottom of the two light holders 18 to increase the brightness of the working area. Rotating frames 20 are fixedly connected to the opposite sides of the two support plates 204. The two rotating frames 20 are symmetrically designed to facilitate the rotation of the rotating rod 202.
[0031] Specifically, support columns 16 are fixedly connected to the four corners of the bottom of the base plate 1. The support columns 16 extend downwards, and the anti-slip sleeves 17 installed at the bottom greatly increase the friction with the ground, which can effectively prevent the mold from moving during operation and ensure operational stability. Light holders 18 are fixed on the left and right sides below the top plate 4, and lighting lamps 19 are connected to the bottom of the two light holders 18. When turned on, they can illuminate the working area of the mold, making it easier for operators to operate accurately. Rotating frames 20 are provided on the opposite sides of the two support plates 204. The rotating frames 20 are symmetrically designed, making it convenient for operators to hold and rotate the rotating rods 202, providing convenience for cleaning up waste from the molding box 15.
[0032] Reference Figure 1 , Figure 4 and Figure 5Both rotating rods 202 are fixedly connected to caps 21 on their front and rear sides. The outer walls of multiple caps 21 are all rounded to prevent the rotating rods 202 from falling off. The bottoms of multiple hydraulic rods 3 are fixedly connected to the top of the base plate 1 at equal intervals. The positioning pin 6 matches the positioning hole opened on the top of the extrusion head 10. The diameter of the card plate 8 is the same as the diameter of the card groove 7. The diameter of the card strip 12 is smaller than the diameter of the insertion groove 11.
[0033] Specifically, caps 21 are fixed to the front and rear sides of the two rotating rods 202. The outer walls of the caps are rounded, which can not only effectively prevent the rotating rods 202 from falling accidentally, but also prevent personnel from being injured during operation. Multiple hydraulic rods 3 are fixed to the top of the base plate 1 at equal intervals to ensure that the top plate 4 is subjected to uniform force and rises and falls smoothly. The positioning pin 6 is precisely matched with the positioning hole on the top of the extrusion head 10 to ensure accurate positioning. The diameter of the clamping plate 8 is adapted to the clamping groove 7, and the diameter of the clamping strip 12 is smaller than that of the insertion groove 11, so that the installation and disassembly operations can be carried out smoothly.
[0034] Working principle: Before the mold starts operating, the clamping plate 8 slides into it. Then, two bolts 9 are threaded on the front and back sides of the top of the clamping plate 8. These bolts are connected to the extrusion head 10. After tightening the bolts 9, the extrusion head 10 is firmly installed at the bottom of the fixed column 5. The bottom of the outer wall of the positioning pin 6 and the front side of the extrusion head 10 both have insertion grooves 11, in which the clamping strip 12 can slide. During operation, the clamping strip 12 is inserted into the insertion grooves 11 of the extrusion head 10 and the positioning pin 6 in sequence to further enhance the connection stability between the positioning pin 6 and the extrusion head 10. The fixed plate 13 is set on the front and back sides of the clamping strip 12. Multiple bolts 14 are threaded on the side of the fixed plate 13 away from each other, and the bolts 14 are threaded to the front and back sides of the extrusion head 10 respectively to ensure that the entire connection structure is firm. When the material is positioned, the hydraulic rod 3 pushes the top plate 4, which drives the extrusion head 10 down. In the forming box 15 fixed to the top of the bottom plate 1, pressure is applied to the material to be stamped to complete the stamping and forming operation of the heat-spreading sheet.
[0035] Furthermore, when the stamping operation is completed and waste accumulates inside the forming box 15, the operator first holds the rotating rod 202 and rotates it to adjust the support plate 204 upward to a suitable position. Then, the telescopic rod 205 is activated, and the telescopic rod 205 begins to extend or retract, pushing the scraper 206 to move back and forth inside the forming box 15. Due to its design of adhering to the inner wall of the forming box 15, the scraper 206 can efficiently and effectively scrape off the waste adhering to the inside of the forming box 15. After the scraper 206 completes the cleaning action, the operator can collect and remove the scraped waste from inside the forming box 15, thereby ensuring that the inside of the forming box 15 is always kept clean.
[0036] The rest of this embodiment is the same as that in Embodiment 1. Features not explained in this embodiment are explained using the methods in Embodiment 1, and will not be repeated here.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
