Description

Technical Field

[0001] This utility model relates to the field of fin mold technology, and in particular to a flange structure for a fin mold. Background Technology

[0002] Air conditioner fins are heat exchange fins used in air conditioners. Most air conditioner fins are made of aluminum or copper. Air conditioner fin molds are high-precision cold stamping progressive dies specially designed for producing air conditioner fins. Air conditioner fin flanging is done by first placing the fins on the lower die support plate, and then pressing the flanging die through the punch fixing plate to press the vertical holes of the fins into holes with a certain height of outward flanging.

[0003] A search revealed a flanging structure for a staggered-tooth fin mold, publication number CN216263157U. This structure includes a mold body comprising an upper mold base and a lower mold base. The upper mold base has four stroke guide pillars at its bottom corners. By setting a lifting structure, the flanging structure of this staggered-tooth fin mold can change the flanging height of the fins, thus making it easier to ensure consistent flanging height and product quality. However, it still has the following drawback: it requires manually adding or reducing the number of lifting blocks to change the height of the flanging blocks, which is time-consuming and labor-intensive, affecting the efficiency of fin flanging processing. To better address the above problems, promote the development of industry technology, and improve core competitiveness, this application proposes a new composition structure (or a new implementation method) that differs from the existing technology. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a flange structure for fin molds.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fin mold flange structure includes a mold body, which includes a lower mold base and an upper mold base. A punch fixing plate is fixedly connected to the bottom of the upper mold base. A flange punch is detachably mounted on the bottom of the punch fixing plate via bolts. The lower mold base includes a support base fixedly connected to the top of the lower mold base. A die fixing plate is detachably mounted on the top of the support base via bolts. A flange die is provided on the top of the die fixing plate to cooperate with the flange punch. The central axes of the flange punch and the flange die are coaxial. A sliding groove communicating with the flange die is provided on one side of the support base. An inclined block that moves along the groove direction is provided in the sliding groove. A pad is provided in the flange die. The bottom end of the pad is integrally formed with an inclined surface that fits against the inclined block. A pull rod is fixedly connected to one side of the inclined block and extends out of the sliding groove. A clamping assembly for fixing the pull rod is provided on the upper surface of the lower mold base. An extrusion assembly for fixing the fin is provided on the upper surface of the support base.

[0007] As a further embodiment of this utility model, the clamping assembly includes a guide groove formed on the upper surface of the lower mold base. The guide groove is located directly below the pull rod. Two clamping blocks are slidably connected in the guide groove. A bidirectional lead screw is rotatably connected in the guide groove, and the bidirectional lead screw passes through the two clamping blocks and is threadedly connected to the two clamping blocks. One end of the bidirectional lead screw is fixedly connected to a connecting shaft, and one end of the connecting shaft extends out of the lower mold base. A locking nut is threadedly connected to the outer side of the connecting shaft.

[0008] As a further improvement of this invention, rubber pads are fixedly connected to the opposite sides of the two clamping blocks.

[0009] As a further embodiment of this utility model, the extrusion assembly includes multiple L-shaped plates, all of which are fixedly connected to the upper surface of the support base. Each of the multiple L-shaped plates has a threaded hole at its top, and a threaded rod is threadedly connected to the threaded hole. A pressure plate is rotatably connected to the bottom end of the threaded rod.

[0010] As a further embodiment of this utility model, a vertical groove is provided on one side of the L-shaped plate, so that the pressure plate can move along the groove.

[0011] As a further embodiment of this utility model, a baffle is provided inside the chute, and a plurality of fixing rods are fixedly connected to one side of the baffle, and the fixing rods are detachably connected to the support base by bolts.

[0012] As a further embodiment of this utility model, the pull rod passes through the baffle, and the upper surface of the pull rod is provided with multiple scale lines.

[0013] As a further embodiment of this utility model, telescopic rods are fixedly connected to the lower mold base and the upper mold base at the four corners.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. By setting the inclined block, the inclined block is pulled to move in the slide. The inclined block and the inclined plate will squeeze the plate upward through the cooperation of the inclined plate itself and the inclined plate of the pad, so as to make it easier to change the height of the pad. This allows the flange structure of the mold to change the flange height of the fin, and thus makes it easier to ensure the consistency of the flange height, thereby ensuring the quality of the product.

[0016] 2. By setting up the extrusion component, the fins can be extruded and fixed by the pressure component during the fin flanging process using the membrane tool, thereby preventing the fins from shifting position during processing and improving the stability of fin processing.

[0017] 3. By using the scale lines in conjunction with the pull rod to move the inclined block, the distance the pull rod moves is proportional to the height the pad moves. Therefore, the height of the pad can be calculated by observing the distance the pull rod moves through the scale lines, which facilitates precise adjustment of the pad height and improves the usability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-3A fin mold flange structure includes a mold body 24, which includes a lower mold base 1 and an upper mold base 2. A punch fixing plate 4 is bolted to the bottom of the upper mold base 2, and a flange punch 5 is detachably bolted to the bottom of the punch fixing plate 4. The lower mold base 1 includes a support base 6 bolted to the top of the lower mold base 1, and a die fixing plate 7 is detachably bolted to the top of the support base 6. A flange die 15, which mates with the flange punch 5, is provided on the top of the die fixing plate 7. The central axes of the flange punch 5 and the flange die 15 are coaxial. A groove 17 communicating with the flange die 15 is provided on one side of the support base 6, and an inclined plane that moves along the groove direction of the groove 17 is provided within the groove 17. The face block 18 has a pad 16 inside the flanging die 15. The bottom end of the pad 16 is integrally formed with an inclined surface that fits against the face block 18. A pull rod 9 is welded to one side of the inclined block 18, and the pull rod 9 extends into a slide groove 17. When adjustment is required, the pull rod 9 is pulled to move the face block 18 in the slide groove 17. During the movement, the inclined block 18 can squeeze the pad 16 upward in the flanging die 15 by the cooperation of its own inclined surface and the inclined surface of the pad 16. This makes it easy to adjust the height of the pad 16, so that the flanging structure of the die can change the flanging height of the fins, and thus more easily ensure the consistency of the flanging height and thus ensure the quality of the product.

[0024] In this invention, the upper surface of the lower mold base 1 is provided with a clamping assembly for fixing the pull rod 9. The clamping assembly includes a guide groove 20 formed on the upper surface of the lower mold base 1, the guide groove 20 being located directly below the pull rod 9. Two clamping blocks 21 are slidably connected within the guide groove 20, and a bidirectional lead screw 23 is rotatably connected within the guide groove 20. The bidirectional lead screw 23 passes through the two clamping blocks 21 and is threadedly connected to the two clamping blocks 21. A connecting shaft 19 is welded to one end of the bidirectional lead screw 23, and one end of the connecting shaft 19 extends out of the lower mold base 1. A locking nut is threadedly connected to the outer side of the connecting shaft 19. After adjusting column 16 to a suitable height, rotate connecting shaft 19. Connecting shaft 19 drives bidirectional lead screw 23 to rotate. The bidirectional lead screw 23, through thread engagement with two clamping blocks 21, drives the two clamping blocks 21 to move towards each other along guide groove 20, thereby clamping and fixing the pull rod 9, thus fixing the height of column 16. Rubber pads 22 are glued to the opposite side of the two clamping blocks 21. The rubber pads 22 can increase the stability of clamping and fixing the pull rod 9. At the same time, tighten the locking nut to fix the connecting shaft 19.

[0025] In particular, the upper surface of the support base 6 is provided with an extrusion assembly for fixing the fins. The extrusion assembly includes multiple L-shaped plates 12, which are welded to the upper surface of the support base 6. Each L-shaped plate 12 has a threaded hole at its top, and a threaded rod 13 is threaded into the threaded hole. A pressure plate 14 is rotatably connected to the bottom end of the threaded rod 13. A vertical groove is provided on one side of the L-shaped plate 12, allowing the pressure plate 14 to move along the groove. The width of the punch fixing plate 4 and the flanging punch 5 is equal to the shortest distance between the two opposing L-shaped plates 12, so that the flanging punch 5 passes through the two L-shaped plates 12 and fits against the die fixing plate 7. The fins are placed on the die fixing plate 7, and then the threaded rod 13 is rotated. The threaded rod 13, through engagement with the threaded hole, pushes the pressure plate 14 to move downward along the vertical groove, so that the pressure plate 14 extrudes and fixes the fins, thereby preventing the fins from shifting position during processing and improving the stability of fin processing.

[0026] It should be noted that a baffle 8 is provided inside the slide 17. Multiple fixing rods 11 are welded to one side of the baffle 8, and the fixing rods 11 are detachably connected to the support base 6 by bolts. The pull rod 9 passes through the baffle 8 and the slide 17 can be exposed through the detachable baffle 8, so that the inclined block 18 can be taken out from the slide 17. Multiple scale lines 10 are provided on the upper surface of the pull rod 9. The moving distance of the pull rod 9 is proportional to the moving height of the pad 16. Therefore, the moving distance of the pull rod 9 can be observed through the scale lines 10 on the pull rod 9, so as to determine the moving height of the pad 16, which facilitates the precise adjustment of the height of the pad 16 and improves the use effect. Telescopic rods 3 are fixed to the four corners between the lower mold base 1 and the upper mold base 2 by bolts. During the movement of the lower mold base 1, the telescopic rods 3 will be squeezed and contracted, so that the telescopic rods 3 guide the movement of the lower mold base 1.

[0027] Working principle: When adjustment is needed, pull rod 9 is moved, which drives inclined block 18 to move within slide groove 17. During the movement, inclined block 18, through the cooperation of its inclined surface with the inclined surface of pad 16, can compress pad 16 to move upward within flanging die 15. Simultaneously, the moving distance of pull rod 9 is proportional to the moving height of pad 16. Therefore, the moving distance of pull rod 9 can be observed through the scale line 10 on pull rod 9 to determine the moving height of pad 16, facilitating precise adjustment of pad 16's height and improving usability. After pad 16 is adjusted to the appropriate height, rotating connecting shaft 19 drives bidirectional lead screw 23 to rotate. The bidirectional lead screw 23, through threaded engagement with two clamping blocks 21, drives the two clamping blocks 21 to move towards each other along guide groove 20, thereby causing the clamping blocks 21 to move upward. 1. The tie rod 9 is clamped and fixed to fix the height of the pad 16, which facilitates the adjustment of the height of the pad 16. This allows the flanging structure of the mold to change the flanging height of the fin, making it easier to ensure the consistency of the flanging height and thus ensuring product quality. After adjustment, the fin is placed on the die fixing plate 7, and then the threaded rod 13 is rotated. The threaded rod 13, through engagement with the threaded hole, pushes the pressure plate 14 to move downward along the vertical groove, so that the pressure plate 14 squeezes and fixes the fin, thereby preventing the fin from shifting position during processing and improving the stability of fin processing. After the work is ready, the upper die seat 2 is moved downward by the press control. The downward movement of the upper die seat 2 drives the flanging punch 5 to enter the flanging die 15, thereby cooperating with the flanging die 15 to squeeze the fin and perform flanging processing on the fin.

[0028] Furthermore, although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
