Description

Technical Field

[0001] This invention relates to the field of mold technology, and in particular to a device for adjusting the height of the flanged hole of an air conditioner fin and a mold. Background Technology

[0002] The heat exchanger fins on an air conditioner are composed of multiple fins stacked together. The spacing between the fins is determined by the flange height of the holes. During production, the mold produces several or dozens of rows of fins simultaneously. The height of the flange holes between each row of fins is subject to very strict requirements. Theoretically, each row should be the same height to ensure that the stacked fins maintain a consistent height and that the number of fins required for each row is consistent when stacked to a certain height.

[0003] The applicant has discovered that the prior art has at least the following technical problems: However, in the actual manufacturing and production process of the mold, due to the influence of various manufacturing and production conditions, even if the same mold is produced in different environments, it is easy to cause inconsistencies in the flange height of each row of fins (such as...). Figure 1 (As shown). From the 1st to the 12th column of fins, the height of the flanged holes in each column is formed by the corresponding flanged punch and die. Due to differences in the machining precision of the flanged punch and die, the height of the flanged holes in each column will vary. Even though the number of fins in each column is the same, the total height will differ. For example, if the flanged hole height is 1.2mm, and two columns of fins have a difference of 0.005mm, after stacking 1000 fins, the difference will be 5mm, which is unacceptable in production. This requires fine-tuning the flanged hole height by 0.005mm, but currently, there is no such rapid adjustment method on the mold. Summary of the Invention

[0004] The purpose of this invention is to provide an air conditioner fin flange hole height adjustment device and mold, so as to solve the technical problem that the flange hole height cannot be quickly adjusted when there is an error in the mold processing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: This invention provides a flange hole height adjustment device, comprising a single-row adjusting slider mechanism disposed between a lower template and a lower mold base; the single-row adjusting slider mechanism includes a lower pad, a plurality of single-row adjusting modules, and a plurality of adjusting components; wherein: The lower pad is provided with several receiving slots; Several of the single-row adjustment modules are arranged one-to-one in the receiving slot; A plurality of the aforementioned adjustment components are configured in a one-to-one correspondence with a plurality of the aforementioned single-column adjustment modules, so as to adjust the height of each of the aforementioned single-column adjustment modules; It also includes an integral adjusting slider mechanism located at the bottom of all the single-row adjusting slider mechanisms; The overall adjusting slider mechanism is movably installed inside the lower mold base, and its overall height can be adjusted during movement to adjust the height of all columns of flanged holes.

[0006] The flange hole height adjustment device of the present invention achieves precise control of the height of each row of flange punches in the mold by setting several receiving slots in the lower pad and installing multiple single-row adjustment modules side by side in them, and using independent adjustment components to fine-tune each module. By driving the single-row adjustment modules to make slight vertical displacements through the adjustment components, the flange height deviation caused by processing errors or wear is effectively eliminated. This structure does not change the original mold body design, only integrating the adjustment device between the lower template and the lower mold base, which is convenient for installation and maintenance. Furthermore, the adjustment process does not require mold disassembly, significantly improving production efficiency and product consistency. The present invention, by setting an integrated adjustment slider mechanism, can simultaneously fine-tune the height of all rows of flange holes without disassembling the mold, compensating for height deviations caused by lower mold base deformation or overall processing errors.

[0007] As a further improvement of the present invention, the single-row adjustment module includes a first single-row inclined slider, a second single-row inclined slider, and a driving component; wherein: The bottom surface of the first single-row inclined slider is a downward-sloping surface; The top surface of the second single-row inclined slider corresponds to the downward-sloping position of the first inclined surface; The driving component is connected to the second single-row inclined slider, which can drive the second single-row inclined slider to be inserted between the first single-row inclined slider and the lower pad. The height of the row of flanged holes can be adjusted by adjusting the insertion depth.

[0008] This invention utilizes the inclined surface cooperation between a first and second single-row inclined slider, employing a driving component to propel the second single-row inclined slider laterally, which is then converted into the vertical lifting and lowering of the first single-row inclined slider, achieving precise adjustment of the flange hole height. This structure offers stable transmission and micron-level adjustment accuracy, making it suitable for online calibration of high-density fin molds. The combination of an overall adjusting slider mechanism and a single-row adjusting module provides dual control, enabling unified correction of overall deviations and independent compensation for local errors, significantly improving mold adaptability and product yield.

[0009] As a further improvement of the present invention, the driving component includes a fixing plate, a locking nut, and an adjusting screw; wherein: The fixing plate is provided with screw holes; The locking nut is screwed onto the adjusting screw; The adjusting screw passes through the screw hole and abuts against the second single-row inclined slider.

[0010] This invention utilizes the engagement of adjusting screws with the screw holes of a fixed plate to precisely move the second single-row inclined slider horizontally, thereby causing the first single-row inclined slider to rise and fall vertically, achieving fine-tuning of the flange hole height. A locking nut is used to lock the position of the adjusting screw, preventing loosening due to vibration and ensuring adjustment stability. This drive structure is simple, reliable, and easy to operate, allowing for rapid adjustments during mold operation intervals, effectively ensuring the stability and consistency of precision in continuous production.

[0011] As a further improvement of the present invention, it also includes a screw plug and a slider return spring; wherein: The bottom of the second single-row inclined slider has a protrusion, and a through hole is provided in the protrusion; The through hole facing the driving component is a threaded hole; The plug is screwed into the threaded hole; One end of the slider return spring abuts against the screw plug, and the other end abuts against the lower pad.

[0012] The slider return spring maintains pre-compression force under normal conditions, ensuring stable positioning of the second single-row inclined slider when no external force is applied. When adjustment is required, the drive component pushes the second single-row inclined slider to overcome the spring force and achieve displacement. After adjustment, the structure remains stable thanks to the combined action of the spring and the locking nut. This reset structure effectively prevents the slider from loosening or shifting, improves the repeatability and safety of adjustment, and ensures long-term high-precision operation of the mold.

[0013] As a further improvement of the present invention, the overall adjusting slider mechanism includes a plurality of lower overall inclined sliders, a plurality of upper overall inclined sliders, and an adjusting member; wherein: Several lower integral inclined sliders are sequentially connected end to end, and the top surface of all the lower integral inclined sliders is an upward inclined surface; Several upper integral inclined sliders are slidably placed on top of several lower integral inclined sliders in a one-to-one correspondence, and the bottom surface of all the upper integral inclined sliders is an upward inclined surface; The adjusting component is connected to the first lower integral inclined slider, which can drive all the lower integral inclined sliders to reciprocate relative to all the upper integral inclined sliders. The height of all columns of flanged holes can be adjusted by adjusting the contact position of the inclined surface.

[0014] The overall adjusting slider mechanism of the present invention drives the lower overall inclined slider and the upper overall inclined slider through the overlapping of their inclined surfaces. The adjusting component drives all the lower overall inclined sliders to move laterally in sync, thereby pushing the upper overall inclined slider to rise and fall vertically as a whole, achieving consistent adjustment of the height of multiple rows of flanged holes. This structure has high repeatability positioning accuracy, and with the single-row fine-tuning module, it can achieve global and local collaborative control, greatly improving the efficiency of mold debugging and molding stability.

[0015] As a further improvement of the present invention, the adjusting component includes an adjusting screw, a first screw fixing block, a second screw fixing block, and an adjusting display; wherein: The first integral inclined slider is provided with a threaded adjustment hole; The first screw fixing block and the second screw fixing block are arranged side by side at intervals; One end of the adjusting screw is screwed into the threaded adjusting hole, and the other end is screwed into the first screw fixing block and the second screw fixing block in sequence; furthermore, the adjusting screw is provided with a boss between the first screw fixing block and the second screw fixing block.

[0016] The adjustment display is mounted on the adjustment screw. The adjustment display is a mechanical digital position display, model number: DA02-02-10-0-E-10-0-I.

[0017] By converting the rotational motion of the adjusting screw into linear displacement, the lower inclined slider moves synchronously, achieving precise control of the flange hole height. The adjustment display provides real-time feedback of the displacement values, ensuring data visualization and traceability throughout the multi-stage adjustment process. The boss restricts the axial movement of the adjusting screw, improving transmission stability. This structure combines precision mechanical transmission with digital display technology, significantly enhancing operational accuracy and mold debugging repeatability, meeting the requirements of high-precision stamping processes.

[0018] As a further improvement of the present invention, the lower integral inclined slider includes a first integral inclined slider, a second integral inclined slider, and a third integral inclined slider; wherein: the slider; the first integral inclined slider, the second integral inclined slider, and the third integral inclined slider are sequentially engaged end-to-end. The second integral inclined slider consists of several parts, which are sequentially connected end to end; The first integral inclined slider is engaged with the first second integral inclined slider; The third integral inclined slider is engaged with the last second integral inclined slider.

[0019] The lower integral inclined slider of this invention adopts a modular splicing structure, which enables rapid assembly and maintenance through end-to-end snap-fit, adapting to different mold width requirements; the adjusting screw passes through the first integral inclined slider and cooperates with the first screw fixing block and the second screw fixing block to achieve axial positioning. Rotating the adjusting screw can drive the first integral inclined slider to slide along the inclined surface, thereby driving the subsequent lower integral inclined sliders to move synchronously; the adjustment display is linked with the adjusting screw to provide real-time feedback on the displacement, ensuring the accuracy and visual control of multi-row flange height adjustment.

[0020] As a further improvement of the present invention, the upper integral inclined slider includes a plurality of fourth integral inclined sliders.

[0021] The upper integral inclined slider of the present invention includes a fourth integral inclined slider, the number of which corresponds one-to-one with the lower integral inclined slider. The inclined surface at the bottom of each fourth integral inclined slider is in close contact with the inclined surface at the top of the corresponding lower integral inclined slider, forming a stable inclined surface transmission pair. Under the drive of the adjusting component, the lower integral inclined slider moves synchronously in the horizontal direction. Through the positive pressure transmission between the inclined surfaces, the fourth integral inclined slider is pushed to rise or fall vertically, realizing the precise adjustment of the height of the flanged insert. Each contact inclined surface is precision ground to ensure smooth transmission without backlash. In conjunction with the adjustment display to read displacement data in real time, the height consistency of multiple rows of flanged holes is controlled within ±0.02mm.

[0022] The present invention provides a mold, including the flange hole height adjustment device.

[0023] The mold of this invention integrates the aforementioned flange hole height adjustment device. Through the overall adjustment slider mechanism and the single-row adjustment slider mechanism, the height of the flange holes of the fins can be adjusted as a whole across all rows within a large range, while also allowing for individual minute adjustments to the height of the flange holes in a single row. When using the mold structure of this invention for production, the height is adjusted through the slider structure in the mold structure. The overall adjustment slider mechanism can adjust the height of the flange holes in all rows together, meeting the production requirements for different flange heights. When the height of one or more rows differs, minute adjustments can be made through the single-row adjustment slider mechanism to achieve a uniform height across all rows.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0028] like Figures 2-11 As shown, the present invention provides a flange hole height adjustment device. It should be noted that the flange hole height adjustment device can be applied to various products that need to be processed with flange holes. In this embodiment, the processing of flange holes on fins is taken as an example for specific description. That is to say, in this embodiment, the flange hole height adjustment device is applied to the mold for processing fin flange holes. Specifically, such as Figure 5 and Figure 6As shown, the flange hole height adjustment device includes a single-row adjusting slider mechanism 9 disposed between the lower template 6 and the lower mold base 7; the single-row adjusting slider mechanism 9 includes a lower pad 92, several single-row adjusting modules, and several adjusting components; wherein: The lower pad 92 has several accommodating slots arranged side by side at intervals; Several single-row adjustment modules are set one-to-one in the receiving groove. The protrusions on both sides of the receiving groove of the lower pad 92 are used to limit the single-row adjustment module to one degree of freedom. Moreover, since the single-row adjustment module is finally installed in the groove of the lower template 6, the single-row adjustment module can only move in the vertical direction and cannot move in the horizontal direction. Several adjustment components are set up one-to-one with several single-column adjustment modules to adjust the height of each single-column adjustment module; It also includes an overall adjusting slider mechanism 8 located at the bottom of all single-row adjusting slider mechanisms 9; The overall adjusting slider mechanism 8 is movably set inside the lower mold base 7, and its overall height can be adjusted during movement to adjust the height of all columns of flanged holes.

[0029] The flange hole height adjustment device of the present invention, by setting several receiving slots in the lower pad 92 and installing multiple single-row adjustment modules one by one in each slot, and cooperating with independent adjustment components to fine-tune each module, achieves precise control of the height of each row of flange punches 12 in the mold. By driving the single-row adjustment modules to make slight displacements in the vertical direction through the adjustment components, the flange height deviation caused by processing errors or wear is effectively eliminated. This structure does not change the original mold body design, and only integrates the adjustment device between the lower template 6 and the lower mold base 7, which is convenient for installation and maintenance, and the adjustment process does not require mold disassembly, greatly improving production efficiency and product consistency. In order to further improve the adjustment efficiency, the present invention sets an overall adjustment slider mechanism 8, which can simultaneously fine-tune the height of all rows of flange holes without disassembling the mold, to compensate for the height deviation caused by deformation of the lower mold base 7 or overall processing errors.

[0030] like Figure 5 and Figure 6 As shown, the single-row adjustment module includes a first single-row inclined slider 94, a second single-row inclined slider 93, and a driving component; wherein: The bottom surface of the first single-row inclined slider 94 is a downward-sloping surface; The top surface of the second single-row inclined slider 93 corresponds to the downward-sloping position of the first inclined surface; The driving component is connected to the second single-row inclined slider 93, which can drive the second single-row inclined slider 93 to be inserted between the first single-row inclined slider 94 and the lower pad 92. The height of the flange hole can be adjusted by adjusting the insertion depth.

[0031] This invention utilizes the inclined surface cooperation between the first single-row inclined slider 94 and the second single-row inclined slider 93. A driving component pushes the second single-row inclined slider 93 to move laterally, which is converted into the vertical lifting and lowering of the first single-row inclined slider 94, achieving precise adjustment of the flange hole height. This structure offers stable transmission and adjustment accuracy down to the micron level, making it suitable for online calibration of high-density fin molds. Combining the overall adjusting slider mechanism 8 with the dual control of the single-row adjusting module, it can uniformly correct overall deviations and independently compensate for local errors, significantly improving mold adaptability and product yield.

[0032] As an optional embodiment of the present invention, the driving component includes a fixing plate 91, a locking nut 95, and an adjusting screw 96; wherein: The fixing plate 91 is fixed to the mold, and the fixing plate 91 is provided with screw holes; the number of screw holes is multiple, the same as the number of single-row adjustment modules; The locking nut 95 is screwed onto the adjusting screw 96 to lock it in place after the adjusting screw 96 is adjusted. The adjusting screw 96 passes through the screw hole and abuts against the second single-row inclined slider 93. By screwing the adjusting screw 96 in or out, the insertion depth of the second single-row inclined slider 93 is adjusted, thereby raising or lowering the vertical height of the first single-row inclined slider 94, thus completing the height adjustment of the flange punch 12 corresponding to the single-row inclined slider. The adjusting screw 96 cooperates with the locking nut 95 to ensure that the adjustment process is stable and controllable, and that the set position remains unchanged even under vibration.

[0033] This invention uses an adjusting screw 96 that engages with the screw hole in the fixing plate 91 to drive the second single-row inclined slider 93 to move precisely horizontally, thereby causing the first single-row inclined slider 94 to rise and fall vertically, achieving fine-tuning of the flange hole height. A locking nut 95 is used to lock the position of the adjusting screw 96, preventing loosening due to vibration and ensuring adjustment stability. This drive structure is simple, reliable, and easy to operate, allowing for rapid adjustment during mold operation intervals, effectively ensuring the stability and consistency of precision in continuous production.

[0034] To achieve automatic reset, such as Figure 7 As shown, the present invention also includes a screw plug 97 and a slider return spring 98; wherein: The bottom of the second single-row inclined slider 93 has a protrusion, and a through hole is provided in the protrusion; The through hole facing the drive component is a threaded hole; The 97-type plug is screwed into the threaded hole; One end of the slider return spring 98 abuts against the screw plug 97, and the other end abuts against the lower pad 92.

[0035] Under normal conditions, the slider return spring 98 maintains a pre-compression force, ensuring stable positioning of the second single-row inclined slider 93 when no external force is applied. When adjustment is required, the drive component pushes the second single-row inclined slider 93 to overcome the spring force and achieve displacement. After adjustment, the structure remains stable thanks to the combined action of the spring and the locking nut 95. This reset structure effectively prevents the slider from loosening or shifting, improves the repeatability and safety of adjustment, and ensures long-term high-precision operation of the mold.

[0036] In this embodiment, as Figure 7 and Figure 8 As shown, the overall adjusting slider mechanism 8 includes several lower overall inclined sliders, several upper overall inclined sliders, and adjusting components; wherein: Several lower integral inclined blocks are sequentially connected end to end, and the top surface of all the lower integral inclined blocks is an upward inclined surface; Several upper inclined sliders are slidably placed on top of several lower inclined sliders, and the bottom surface of all upper inclined sliders is an upward-sloping surface. The adjusting component is connected to the first lower integral inclined slider, which can drive all the lower integral inclined sliders to reciprocate relative to all the upper integral inclined sliders. The height of all columns of flanged holes can be adjusted by adjusting the contact position of the inclined surface.

[0037] The overall adjusting slider mechanism 8 of the present invention drives the lower overall inclined slider and the upper overall inclined slider through the overlapping of their inclined surfaces. The adjusting component drives all the lower overall inclined sliders to move laterally in sync, thereby pushing the upper overall inclined slider to rise and fall vertically as a whole, realizing the consistent adjustment of the height of multiple rows of flanged holes. This structure has high repeatability positioning accuracy, and with the single-row fine-tuning module, it can realize global and local collaborative control, greatly improving the mold debugging efficiency and molding stability.

[0038] Furthermore, such as Figure 8 and Figure 9 As shown, the adjusting component includes an adjusting screw 85, a first screw fixing block 86, a second screw fixing block 87, and an adjusting display 88; wherein: The first lower integral inclined slider is provided with a threaded adjustment hole; The first screw fixing block 86 and the second screw fixing block 87 are arranged side by side at intervals; One end of the adjusting screw 85 is screwed into the threaded adjusting hole, and the other end is screwed into the first screw fixing block 86 and the second screw fixing block 87 in sequence; furthermore, the adjusting screw 85 is provided with a boss between the first screw fixing block 86 and the second screw fixing block 87.

[0039] The adjustment display 88 is mounted on the adjustment screw 85. The adjustment display 88 is a mechanical digital position display, model number: DA02-02-10-0-E-10-0-I.

[0040] By converting the rotational motion of the adjusting screw 85 into linear displacement, the lower inclined slider moves synchronously, achieving precise control of the flange hole height. The adjusting display 88 provides real-time feedback of the displacement value, ensuring data visualization and traceability during multi-stage adjustments. The boss restricts the axial movement of the adjusting screw 85, improving transmission stability. This structure combines precision mechanical transmission with digital display technology, significantly enhancing operational accuracy and mold debugging repeatability, meeting the requirements of high-precision stamping processes.

[0041] like Figure 8 and Figure 9 As shown, the lower integral inclined slider includes a first integral inclined slider 81, a second integral inclined slider 82, and a third integral inclined slider 83; wherein: the slider; the first integral inclined slider 81, the second integral inclined slider 82, and the third integral inclined slider 83 are sequentially engaged end-to-end. The second integral inclined slider 82 consists of several units, which are sequentially connected end to end; The first integral inclined slider 81 is engaged with the first second integral inclined slider 82; The third integral inclined slider 83 is engaged with the last second integral inclined slider 82.

[0042] The lower integral inclined slider of this invention adopts a modular splicing structure, which enables rapid assembly and maintenance through end-to-end snap-fit, adapting to different mold width requirements; the adjusting screw 85 passes through the first integral inclined slider 81 and cooperates with the first screw fixing block 86 and the second screw fixing block 87 to achieve axial positioning. Rotating the adjusting screw 85 can drive the first integral inclined slider 81 to slide along the inclined surface, thereby driving the subsequent lower integral inclined sliders to move synchronously; the adjusting display 88 is linked with the adjusting screw 85 to provide real-time feedback on the displacement, ensuring the accuracy and visual control of multi-row flange height adjustment.

[0043] like Figure 8 and Figure 9 As shown, as a further improvement of the present invention, the upper integral inclined slider includes a plurality of fourth integral inclined sliders 84.

[0044] The upper integral inclined slider of the present invention includes a fourth integral inclined slider 84, the number of which corresponds one-to-one with the lower integral inclined slider. The inclined surface at the bottom of each fourth integral inclined slider 84 is closely fitted with the inclined surface at the top of the corresponding lower integral inclined slider, forming a stable inclined surface transmission pair. Under the drive of the adjusting component, the lower integral inclined slider moves synchronously in the horizontal direction. Through the positive pressure transmission between the inclined surfaces, the fourth integral inclined slider 84 is pushed to rise or fall vertically, realizing the precise adjustment of the height of the flanged insert. Each contact inclined surface is precision ground to ensure smooth transmission without backlash. In conjunction with the adjustment display 88, the displacement data is read in real time to ensure that the height of multiple rows of flanged holes is controlled within ±0.02mm.

[0045] like Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 As shown, the present invention provides a mold including a flange hole height adjustment device.

[0046] In this embodiment, the mold includes an upper mold base 1, a punch mounting plate 2, an upper backing plate 3, a bushing mounting plate 4, a concave mold plate 5, a lower mold plate 6, a lower mold base 7, a limiting post 10, a stripper bushing 11, a flanging punch 12, a forming spring 13, a stripper spring 14, a lower backing plate return spring 15, and a limiting post return spring 16. The flanging hole height adjustment device includes an overall adjusting slider mechanism 8 and a single-row adjusting slider mechanism 9.

[0047] Furthermore, the mold of this invention achieves flanging hole forming through the concave template 5, limiting post 10, unloading bushing 11, and flanging punch 12; the height is adjusted by combining the overall adjusting slider mechanism 8 and the single-row adjusting slider mechanism 9, wherein the overall adjusting slider mechanism 8 can adjust the height of the flanging holes of all rows together to meet the production requirements of different flanging heights; during the fin production process, when the height of one or more rows of the 12 rows is different from the height of the other rows, it can be adjusted by the single-row adjusting slider mechanism 9 until the height is consistent. Each row of the single-row adjusting slider mechanism 9 has an individual slider, and each row can be adjusted independently without interference.

[0048] The height of the flanging hole is determined by the distance the flanging punch 12 enters the concave template 5; the distance the flanging punch 12 enters the concave template 5 is determined by the distance when the limiting post 10 moves downward and contacts the lower pad 92 or the first single-row inclined slider 94; the adjustment of the vertical movement distance of the lower pad 92 is achieved through the overall adjusting slider mechanism 8; the vertical movement distance of the first single-row inclined slider 94 is achieved through the single-row adjusting slider mechanism 9. During installation, the single-row adjusting slider mechanism 9 is mounted on the overall adjusting slider mechanism 8.

[0049] In the integrated adjusting slider mechanism 8, the first integrated inclined slider 81, the second integrated inclined slider 82, and the third integrated inclined slider 83 are connected as a whole through their own U-shaped structure. The threaded hole on the side of the first integrated inclined slider 81 is connected to the adjusting screw 85. The adjusting screw 85 is fixed by the first screw fixing block 86 and the second screw fixing block 87 and can only rotate. When the adjusting screw 85 rotates, it drives the first integrated inclined slider 81, the second integrated inclined slider 82, and the third integrated inclined slider 83 to move horizontally through the threads. The first screw fixing block 86 and the second screw fixing block 87 are used to limit the horizontal movement of the adjusting screw 85. The adjustment display 88 is used to display the amount of adjustment. The horizontal movement of the first integrated inclined slider 81, the second integrated inclined slider 82, and the third integrated inclined slider 83, as well as the inclined surface structure on them, enable the fourth integrated inclined slider 84 to move up and down, thereby enabling the single-row adjusting slider mechanism 9 to move up and down.

[0050] In the single-row adjusting slider mechanism 9, the second single-row inclined slider 93 and the first single-row inclined slider 94 are installed in the receiving groove of the lower pad 92. The first single-row inclined slider 94 is fixed by the lower template 6 and the groove in the lower pad 92, so that it can only move up and down. The second single-row inclined slider 93 can be adjusted by the through-hole adjusting screw 96 to move horizontally. The horizontal movement of the second single-row inclined slider 93 and its inclined surface structure enable the first single-row inclined slider 94 to move up and down, thereby enabling the single-row limiting post 10 to move up and down. Because the first single-row inclined slider 94 and the second single-row inclined slider 93 of each row do not interfere with each other, they can be adjusted independently, thereby enabling the height of each row of limiting posts 10 to be adjusted independently. The slider return spring 98 is used to reset the second single-row inclined slider 93 to the fixed plate 91, the screw plug 97 is used to adjust the magnitude of the reset force, and the locking nut 95 is used to prevent the adjusting screw 96 from loosening.

[0051] Since the diameter of the limiting post 10 is larger than the width of the first single-row inclined slider 94, when the upper plane of the first single-row inclined slider 94 is adjusted to be below the upper plane of the lower pad 92, the bottom surface of the limiting post 10 contacts the lower pad 92. This situation is used to adjust the height of the flange hole as a whole. When the upper plane of the first single-row inclined slider 94 is adjusted to be above the upper plane of the lower pad 92, the bottom surface of the limiting post 10 contacts the first single-row inclined slider 94. This situation is used to adjust the height of the flange hole in a single row.

[0052] Specifically, such as Figures 2-11 As shown, the single-row adjusting slider mechanism 9 allows for individual adjustment of the height of the flange holes in each row of fins. When the height of one or more of the 12 rows differs from the heights of the other rows, the single-row adjusting slider mechanism 9 can be used to adjust them until the heights are consistent. Each row can be adjusted independently without interference. Note: The above description and accompanying drawings of this invention use 12 rows of fins as an example. Of course, fins with other numbers of rows or other products can also be applied. This invention does not limit the number of rows.

[0053] During installation, the overall adjusting slider is inserted into the groove of the lower mold base 7, and the overall adjusting slider can slide within the groove of the lower mold base 7. The single-row adjusting slider mechanism 9 is inserted into the groove of the lower template 6, and the single-row adjusting slider mechanism 9 slides up or down within the groove of the lower template 6. The lower template 6 and the lower mold base 7 are fixed by mounting screws.

[0054] The mold of this invention integrates the aforementioned flange hole height adjustment device. Through the overall adjustment slider mechanism 8 and the single-row adjustment slider mechanism 9, the height of the fin flange holes can be adjusted as a whole across all rows within a large range, while also allowing for individual minute adjustments to the height of each single row of flange holes. When using the mold structure of this invention for production, height adjustment is performed through the slider structure within the mold structure. The overall adjustment slider mechanism 8 can adjust the height of the flange holes in all rows simultaneously, meeting production requirements for different flange heights. When one or more rows have different heights, minute adjustments can be made through the single-row adjustment slider mechanism 9 to achieve a uniform height across all rows.

[0055] The products described in this invention are not limited to air conditioning fins, but also include other products that require adjustment of the height of the flange holes.
