Description

Technical Field

[0001] This utility model relates to a forming and punching die for a solar electronic box casting, belonging to the technical field of molds. Background Technology

[0002] A solar electronic box is an integrated enclosure that incorporates electronic components in solar panel assembly. It contains circuit boards, electronic components, power supplies, and other functional modules. This type of solar electronic box is mainly formed in one piece by casting, and it needs to meet the requirements of heat dissipation while ensuring structural strength.

[0003] There is currently a casting body for a solar electronic box, which includes a box body with a cavity. The box body has a first side wall and a second side wall arranged opposite to each other. The first side wall has a casting port remnant extending away from the cavity direction. The second side wall has several exhaust end remnants extending away from the cavity direction. The bottom wall of the box body is provided with a through-connecting post and several heat dissipation fins.

[0004] After the solar electronic box is cast, the casting body needs to be cut and removed from the remaining parts of the casting port and the exhaust end. In addition, the outer peripheral wall and heat dissipation fins need to be shaped. In traditional processes, cutting equipment is generally used to remove the remaining parts, and then the shaping operation is carried out by using a contour forming mold.

[0005] Because the casting gate residue is firmly connected to the box body, traditional cutting or punching processes can be difficult and inefficient. In particular, large cutting forces can cause deformation of the box body and leave cutting residue. In addition, because removing the residue will cause deformation of the box body, large tolerances often occur during the later mold shaping process, which cannot meet the product assembly requirements, resulting in a very low product qualification rate. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of the existing technology and to propose a forming and punching die for solar electronic box castings, which addresses the problems of low efficiency and low product qualification rate caused by the step-by-step cutting and shaping of traditional residual parts.

The forming and punching die includes a first die base and a second die base having relative opening and closing displacement; The first mold base includes a cavity platform that mates with the cavity and a support ring platform located on the outer periphery of the cavity platform. The support ring platform is provided with a punching tool holder for punching the casting gate residue. The second mold base includes a shaping chamber for cooperating with the cavity platform and a punching engagement part for cooperating with the punching blade holder. The shaping chamber is provided with a positioning protrusion that cooperates with the through-connecting post and fin shaping grooves that correspond one-to-one with the heat dissipation fins.

[0008] Preferably, the shaping chamber includes two opposing shaping sidewalls and a pressing and positioning mechanism located between the two shaping sidewalls and cooperating with the second sidewall. The pressing and positioning mechanism includes pressing and positioning abutment portions that correspond one-to-one with the exhaust end residue portions.

[0009] Preferably, the punching cutter holder includes a slider blade with lifting displacement and a driving part for driving the slider blade to lift displacement, and the second mold base is provided with a driving pressure block for cooperating with the driving part.

[0010] Preferably, the cavity stage includes a stage base and several detachable assembly and shaping blocks disposed on the stage base.

[0011] Preferably, any of the splicing and shaping blocks is provided with a numbered label.

[0012] Preferably, the cavity platform is provided with a plurality of cavity positioning parts for positioning and cooperating with the cavity.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in the present application can be combined with each other.

[0029] This utility model provides a forming and punching die for a solar electronic box casting, such as... Figure 8 and Figure 9 As shown, the solar electronic box casting includes a box body 100 with a cavity 200. The box body 100 has a first side wall and a second side wall arranged opposite to each other. The first side wall has a casting port residue 110 extending away from the cavity direction. The second side wall has a plurality of exhaust end residues 120 extending away from the cavity direction. The bottom wall of the box body is provided with a through-connecting post 130 and a plurality of heat dissipation fins 140.

[0030] like Figures 1 to 7 As shown, the forming and punching die includes a first die holder 1 and a second die holder 2 with relative opening and closing displacement.

[0031] The first mold base 1 includes a cavity platform 3 that mates with the cavity, and a support ring platform located on the outer periphery of the cavity platform 3. The support ring platform is provided with a punching tool holder 4 for punching the remaining part of the casting gate.

[0032] The second mold base 2 includes a shaping chamber 5 for cooperating with the cavity platform and a punching engagement part 6 for cooperating with the punching cutter 4. The shaping chamber 5 is provided with a positioning protrusion 51 that cooperates with the through-connecting pile and a fin shaping groove 52 that corresponds one-to-one with the heat dissipation fins.

[0033] Detailed implementation process and principle explanation: During the punching and shaping process of the solar electronic box casting, the box body 100 is first mounted on the cavity platform 3 of the first mold base 1, so that the box body is mounted upside down with its bottom wall facing the top.

[0034] After the workpiece is mounted, the first mold base and the second mold base are closed. During the mold closing process, the shaping chamber 5 and the cavity platform 3 cooperate to form a shaping chamber to lock and shape the workpiece. At the same time, the punching part 6 and the punching knife holder 4 form a punching force on the casting gate residue 110 to punch and cut it.

[0035] This ensures that the products are punched and shaped using the same mold, resulting in a higher product qualification rate.

[0036] In one specific embodiment, the shaping chamber 5 includes two oppositely arranged shaping sidewalls 53 and a pressing and positioning mechanism 54 located between the two shaping sidewalls and cooperating with the second sidewall. The pressing and positioning mechanism includes a pressing and positioning abutment part 540 that corresponds one-to-one with the exhaust end residual part.

[0037] Specifically, the residual part at the exhaust end is generally small, and its cutting usually does not cause significant product deformation. In this case, the residual part at the exhaust end of the original casting, namely the two shaping sidewalls 53, is used to achieve top-press shaping of the two sidewalls of the box. For the second sidewall, the residual part at the exhaust end is pressed, thereby indirectly providing indirect pressure on the second sidewall. This results in a relative open circuit between the first and second sidewalls during the shaping of the outer peripheral wall of the box. At this time, the punching stress of the first sidewall is eliminated to a certain extent, and the second sidewall also receives a corresponding indirect effect. This prevents damage to the box from large stress during punching and reduces the product scrap rate.

[0038] In one specific embodiment, the punching cutter holder 4 includes a slider cutter 41 with lifting displacement and a driving part 42 for driving the slider cutter to lift displacement. The second mold holder 2 is provided with a driving pressure block 20 for cooperating with the driving part.

[0039] Specifically, under normal circumstances, the mold closing stroke can meet the relative punching and cutting requirements. However, because the stroke is affected by the mold closing contact, there may sometimes be residual material that is not completely cut off.

[0040] In this case, a slider blade 41 with lifting displacement is used. When the driving block 20 presses against the driving part 42, it has a lifting stroke, which can ensure complete cutting.

[0041] The driving principle is explained in detail. The driving block 20 has a vertical displacement, while the driving unit 42 is a carrier with a horizontal reset stroke displacement. It can convert the vertical displacement of the driving block 20 into a horizontal displacement, and then, through the cooperation of the horizontal displacement and the wedge block, realize the lifting and lowering control of the slider blade 41. There are many types of such structures. As long as the driving structure can realize the conversion of the downward stroke of the driving block 20 into the lifting stroke of the slider blade 41, it is within the protection scope of this case.

[0042] In one specific embodiment, the cavity stage 3 includes a stage base 31 and a plurality of detachable assembly and shaping blocks 32 disposed on the stage base. Each assembly and shaping block is marked with a number.

[0043] This design facilitates assembly and modification, and only requires partial modifications to meet the needs of different products.

[0044] In one specific embodiment, the cavity stage 3 is provided with a plurality of cavity positioning parts 30 for positioning and cooperating with the cavity.

[0045] This ensures that the mounting position of the enclosure is more reliable and stable, and that positional deviations are less likely to occur.

[0046] In one specific embodiment, the second mold base 2 includes a shaping module 7, a shaping chamber is disposed on the shaping module, and the shaping module is detachably disposed within the second mold base.

[0047] The need for efficient shape change is met by replacing the shaping module 7.

[0048] In one specific embodiment, the shaping module 7 is composed of a plurality of shaping splicing blocks 70, and any shaping splicing block is detachably mounted on the second mold base.

[0049] The combination of the shaping module 7 is so convenient, and the relative gaps between the shaping splicing blocks 70 meet certain stress release requirements, making the shaping more reliable and ensuring accuracy.

[0050] As can be seen from the above description, this utility model meets the requirements for simultaneous forming and punching of castings, improving the efficiency of forming and punching operations. It eliminates the relative deformation error of step-by-step operations, significantly improving the forming effect while ensuring proper cutting. The mold design is simple and ingenious, easy to assemble, and provides stress relief during forming, resulting in a significant improvement in product qualification rate.

[0052] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
