Description

Technical Field

[0001] This utility model relates to the field of radiator processing technology, and in particular to a radiator stretching strip cutting mold. Background Technology

[0002] In modern industrial production, radiators are key components of electronic and mechanical equipment, and their manufacturing quality and precision directly affect the performance and lifespan of the equipment. Radiators are typically manufactured from sheet metal through a stretching process, during which edge trimming is often performed simultaneously to ensure dimensional accuracy and reduce subsequent processing steps.

[0003] The installation and replacement process of traditional molds is quite cumbersome. When changing molds of different specifications, tools are needed to disassemble them one by one, which takes a long time and affects the continuity of production. In addition, the blanks are prone to displacement during processing, which can lead to product defects and increase the scrap rate. Utility Model Content

[0004] In view of the technical problems in the existing technology, the installation and replacement process of traditional molds is relatively cumbersome. When changing molds of different specifications, tools are needed to disassemble them one by one, which takes a long time and affects the continuity of production. In addition, the blank is prone to displacement during processing, resulting in product defects and increasing the scrap rate. This utility model provides a heat sink stretch strip trimming mold.

[0005] The technical solution adopted by this utility model is: a radiator stretching strip trimming mold, including a base, a lower mold base, and an upper mold base. The lower mold base has a stretching die and a trimming groove inside. The lower surface of the upper mold base is provided with a stretching punch and a trimming knife. Two symmetrical support rods are fixedly installed on both sides of the base. Mounting plates are fixedly installed on the tops of the four support rods. A hydraulic rod is fixedly installed above the mounting plate. The hydraulic rod passes through the mounting plate, and the upper mold base is installed at the bottom of the hydraulic rod. The interior of the base and the area below the hydraulic rod are installed with... The system includes a disassembly and assembly assembly that facilitates quick assembly and disassembly of the lower and upper mold bases. The assembly includes a mounting groove and a mounting rod. A fixing assembly is installed below the upper mold base to secure the blank. By setting corresponding structures for the stretching die and stretching punch, and the trimming groove and trimming blade, the system achieves integrated operation of stretching and trimming of the radiator blank. The disassembly and assembly assembly enables quick assembly and disassembly of the lower and upper mold bases, facilitating mold replacement for different radiator specifications. The fixing assembly ensures the stability of the blank during processing, preventing positional shifts and guaranteeing product quality.

[0006] Furthermore, the number of mounting slots is four and they are arranged in a rectangular array on the upper surface of the base. The number of mounting rods is four and they are all fixedly installed below the lower mold base. The positions of the four mounting rods correspond to the positions of the four mounting slots. The rectangular array design of the four mounting slots and mounting rods ensures the precise positioning of the lower mold base on the base and improves the assembly accuracy of the mold.

[0007] Furthermore, two symmetrical sliding rods are slidably connected to both sides of the interior of the base. The two sliding rods on the same side penetrate one side surface of the base and are slidably connected to the base. A handle is fixedly installed at one end of the two sliding rods on the same side. A snap-fit ​​block is fixedly installed at one end of each of the four sliding rods. A slot that matches the snap-fit ​​block is opened on one side of each of the four mounting rods. The sliding rods can be easily controlled by the handles, thereby realizing the quick engagement and disengagement of the snap-fit ​​block and the slot, simplifying the disassembly and assembly operation.

[0008] Furthermore, the upper surface of the snap-fit ​​block is sloped, and the side away from the slot is higher. The sloped design allows the mounting rod to automatically push the snap-fit ​​block open during insertion.

[0009] Furthermore, a sliding plate is fixedly installed between the two sliding rods on the same side. The sliding plate is slidably connected inside the base. A plurality of first springs are fixedly installed on the side of the sliding plate away from the locking block in a linear array. The other end of the plurality of first springs is fixedly connected to the base. The elastic force of the first springs ensures that the locking block can automatically reset and lock into the slot after the mounting rod is inserted.

[0010] Furthermore, the upper surface of the upper mold base is provided with multiple threaded holes, and a connecting plate is fixedly installed at the bottom of the hydraulic rod. The surface of the connecting plate is provided with mounting holes corresponding to the multiple threaded holes. The upper mold base is fixedly connected to the connecting plate by bolts, which facilitates quick connection or separation of the upper mold base and the hydraulic rod, thereby improving the efficiency of mold replacement.

[0011] Furthermore, the fixing assembly includes a fixing plate disposed below the upper die base. The surface of the fixing plate has through holes that fit with the stretching punch and the trimming blade. Fixing blocks are fixedly installed on both sides of the fixing plate and the upper die base. Connecting rods are fixedly installed above the fixing blocks on both lower sides. The two connecting rods pass through the fixing blocks on both upper sides and are slidably connected to them. A second spring is fixedly installed on the surface of each of the two connecting rods. The combination of the fixing plate and the second spring ensures the stable fixing of the blank during the processing, prevents the blank from shifting, and ensures the dimensional accuracy of the product. The through hole design ensures that the stretching punch and the trimming blade work normally without interfering with the processing flow.

[0012] Furthermore, limit blocks are fixedly installed at the top of both connecting rods. The limit blocks are located above the upper fixed block. The setting of the limit blocks can effectively prevent the connecting rods from slipping out of the upper fixed block and avoid the fixed plate from separating from the upper mold base.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model achieves integrated operation of stretching and forming of radiator blanks and trimming by setting corresponding structures of stretching die and stretching punch, trimming groove and trimming knife. The assembly and disassembly components enable quick assembly and disassembly of the lower die base and upper die base, which is convenient for changing the mold according to different specifications of radiators. It solves the problem that the installation and replacement process of traditional molds is relatively cumbersome. When changing molds of different specifications, it is necessary to disassemble them one by one with the help of tools, which takes a long time and affects the continuity of production.

[0015] 2. Secondly, this utility model ensures the stability of the billet during processing by using a fixing component, avoiding positional displacement, guaranteeing product quality, and solving the problem that billets are prone to displacement during processing, leading to product defects and increasing scrap rate.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The following is in conjunction with the appendix Figures 1-5 The present invention will be further described below.

[0025] In order to solve the problems existing in the background art, this application proposes the following technical solution: a heat sink stretching strip trimming mold.

[0026] The specific technical solution includes a base 1, a lower mold base 2, and an upper mold base 3. The lower mold base 2 has a drawing die 201 and a trimming groove 202 inside. The lower surface of the upper mold base 3 is provided with a drawing punch 301 and a trimming blade 302. Two symmetrical support rods 4 are fixedly installed on both sides of the base 1. Mounting plates 5 are fixedly installed on the top of the four support rods 4. A hydraulic rod 6 is fixedly installed above the mounting plate 5. The hydraulic rod 6 passes through the mounting plate 5, and the upper mold base 3 is installed at the bottom of the hydraulic rod 6. A disassembly and assembly assembly 7 is installed inside the base 1 and below the hydraulic rod 6 to facilitate quick disassembly and assembly of the lower mold base 2 and the upper mold base 3. The disassembly and assembly assembly 7 includes a mounting groove 701 and a mounting rod 7. 02. A fixing component 8 is installed below the upper die base 3 to facilitate the fixing of the blank. When the hydraulic rod 6 pushes the upper die base 3 down, the stretching punch 301 and the stretching die 201 close, squeezing and stretching the blank placed in the die to form the shape required for the radiator. After the stretching process is completed, the upper die base 3 continues to descend, and the trimming knife 302 cooperates with the trimming groove 202 to cut off the excess part of the edge of the stretched blank, ensuring the dimensional accuracy of the radiator. The disassembly and assembly component 7 is used to realize the quick disassembly and assembly of the lower die base 2 and the base 1, and the upper die base 3 and the hydraulic rod 6, so as to facilitate the replacement of molds according to different specifications of radiators. The fixing component 8 is used to fix the blank during processing to prevent its position from shifting.

[0027] Reference Figures 1 to 4As shown, there are four mounting slots 701 arranged in a rectangular array on the upper surface of the base 1. There are four mounting rods 702, all fixedly installed below the lower mold base 2. The positions of the four mounting rods 702 correspond to the four mounting slots 701. Two symmetrical sliding rods 703 are slidably connected to both sides of the interior of the base 1. The two sliding rods 703 on the same side penetrate one side surface of the base 1 and are slidably connected to it. A handle 704 is fixedly installed at one end of each of the two sliding rods 703 on the same side. A locking block 705 is fixedly installed at one end of each of the four sliding rods 703. A slot 706 that matches the locking block 705 is opened on one side of each of the four mounting rods 702. The upper surface of the locking block 705 is sloped and... A sliding plate 707 is fixedly installed between two sliding rods 703 on the same side of the side of the slot 706, which is higher than the side of the base 1. The sliding plate 707 is slidably connected to the inside of the base 1. Multiple first springs 708 are fixedly installed on the side of the sliding plate 707 away from the snap block 705. The other ends of the multiple first springs 708 are fixedly connected to the base 1. Multiple threaded holes 709 are opened on the upper surface of the upper mold base 3. A connecting plate 710 is fixedly installed on the bottom of the hydraulic rod 6. The surface of the connecting plate 710 is opened with mounting holes 711 corresponding to the multiple threaded holes 709. The upper mold base 3 is fixedly connected to the connecting plate 710 by bolts. The four mounting rods 702 below the lower mold base 2 are aligned with the mounting grooves 701 of the base 1 and inserted. Since the upper surface of the snap-fit ​​block 705 is inclined, when the mounting rod 702 descends, it will squeeze the inclined surface, push the sliding rod 703 to slide outward and compress the first spring 708; when the mounting rod 702 is fully inserted, the first spring 708 returns to its original position, causing the snap-fit ​​block 705 to snap into the slot 706 of the mounting rod 702, thus completing the installation of the lower mold base 2. When disassembling, pull the handles 704 on both sides, and the sliding rod 703 will drive the snap-fit ​​block 705 to disengage from the slot 706, so that the lower mold base 2 can be removed from the base 1. The upper mold base 3 is fixed to the connecting plate 710 at the bottom of the hydraulic rod 6 by bolts. When disassembling, the bolts can be unscrewed to separate it, realizing quick replacement.

[0028] Reference Figure 1 , Figure 4 and Figure 5As shown, the fixing assembly 8 includes a fixing plate 801 disposed below the upper mold base 3. The surface of the fixing plate 801 has through holes 802 that mate with the stretching punch 301 and the trimming blade 302. Fixing blocks 803 are fixedly installed on both sides of the fixing plate 801 and the upper mold base 3. Connecting rods 804 are fixedly installed above the lower two fixing blocks 803. The two connecting rods 804 pass through the upper two fixing blocks 803 and are slidably connected to them. Second springs 805 are fixedly installed on the surfaces of both connecting rods 804. The top ends of both connecting rods 804... A limiting block 806 is fixedly installed above the upper fixing block 803. When the upper die base 3 descends, the fixing plate 801 first contacts the blank. As the upper die base 3 continues to descend, the connecting rod 804 slides relative to the fixing block 803, and the second spring 805 is compressed, generating a downward elastic force, which makes the fixing plate 801 press the blank tightly. The through hole 802 on the surface of the fixing plate 801 provides movement space for the stretching punch 301 and the trimming knife 302, without affecting normal processing. The limiting block 806 is used to prevent the connecting rod 804 from coming out of the fixing block 803.

[0029] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0030] In use, align the four mounting rods 702 below the lower die base 2 with the four mounting slots 701 on the upper surface of the base 1 and insert them vertically downwards. During insertion, the mounting rods 702 press against the inclined surface of the snap-fit ​​block 705, pushing the sliding rod 703 to slide outwards and compressing the first spring 708. When the mounting rods 702 are fully inserted into the mounting slots 701, the first spring 708 returns to its original position, causing the snap-fit ​​block 705 to snap into the slot 706 of the mounting rod 702, thus fixing the lower die base 2. Align the threaded hole 709 on the upper surface of the upper die base 3 with the mounting hole 711 of the bottom connecting plate 710 of the hydraulic rod 6, and tighten the bolts to fix the upper die base 3 to the hydraulic rod 6. Place the radiator blank to be processed above the stretching die 201 of the lower die base 2, ensuring that the center of the blank is aligned with the center of the die. Start the hydraulic rod 6 to push the upper die base 3 down slowly. At this time, the fixing plate 801 below the upper die base 3 first contacts the surface of the blank. As the upper die base 3 continues to descend, the connecting rod 804 slides upward relative to the fixing blocks 803 on both sides of the upper die base. The second spring 805 is compressed and generates a downward elastic force, causing the fixing plate 801 to tightly press the blank. The hydraulic rod 6 continues to push the upper die base 3 downward. The stretching punch 301 on the lower surface of the upper die base 3 passes through the through hole 802 of the fixing plate 801 and closes with the stretching die 201 of the lower die base 2, extruding and stretching the blank to form the preset shape of the radiator. After the stretching process is completed, the hydraulic rod 6 drives the upper die base 3 to continue descending. The trimming knife 302 on the upper die base 3 passes through the through hole 802 of the fixing plate 801 and cooperates with the trimming groove 202 of the lower die base 2 to cut off the excess part of the edge of the stretched blank. After the trimming is completed, the hydraulic rod 6 drives the upper die base 3 to return to its original position, and the stretching punch 301 and the trimming knife 302 disengage from the lower die base 2. After the upper die base 3 returns to its initial position, the processed radiator workpiece can be removed.
