Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a stamping die for an air conditioner front cover with chamfer forming function. Background Technology

[0002] In the air conditioner manufacturing process, the front cover of the air conditioner is an important appearance and protective component, and its processing quality directly affects the overall aesthetics and performance of the air conditioner. Currently, the production of the front cover of the air conditioner mainly uses stamping dies for forming. When stamping the front cover of the air conditioner, traditional stamping dies can usually only complete the basic outline and shape stamping. For the processing of the chamfered edges of the front cover, it is often necessary to achieve this through additional secondary processing steps after stamping, such as milling and grinding. This processing method has the following drawbacks: on the one hand, secondary processing increases the production steps, leading to a longer production cycle, low production efficiency, and thus increased production costs.

[0003] On the other hand, during secondary processing, it is difficult to ensure the consistency and accuracy of the chamfer dimensions, which can easily lead to problems such as inconsistent chamfer sizes and surface roughness that do not meet requirements. This affects the appearance quality and assembly accuracy of the air conditioner front cover, reducing the product qualification rate. In view of this, we propose a stamping die for an air conditioner front cover with chamfer forming function. Utility Model Content

[0015] This setting enables airflow cooling, ensuring that cooling is performed immediately after each stamping cycle.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. This utility model achieves the direct forming of the beveled corners of the air conditioner front cover during the stamping process by setting a beveled corner punch that is adapted to the size of the forming chamber, and an ejector plate and ejector disc that are adapted to the lower groove and the annular groove respectively. When the lower template and the upper template are engaged, the beveled corner punch and the beveled corner die work together to complete the beveled corner processing of the blank in one stamping, without the need for a secondary process, which greatly shortens the production cycle compared with the traditional method.

[0018] 2. This utility model achieves stable ejection and precise demolding of the workpiece after stamping by setting detachable ejector plates and ejector discs at the ends of the telescopic shafts of the first and third cylinders, and setting positioning holes in the lower groove to cooperate with the guide rod of the ejector plate. The ejector plate and ejector disc smoothly push out the formed front cover plate under the drive of the cylinder, avoiding the surface scratches and deformation problems caused by the large demolding force in traditional demolding. At the same time, the guide structure ensures the accuracy of the ejection process, significantly improves product quality, extends the service life of the mold, and reduces the scrap rate.

[0019] 3. This utility model achieves flexible mold installation and rapid heat dissipation by setting up symmetrical second cylinders to support the upper template and equipping the guide corner die and guide corner punch with a blower and air pipe with a fan on one side. The second cylinder facilitates the adjustment of the upper template position and realizes normal mold opening and closing operations. After each stamping, the blower drives the airflow through the air pipe to quickly dissipate heat from the mold, allowing the mold to cool down quickly before the next stamping, reducing waiting time, improving production continuity, reducing mold wear caused by high temperature, extending the mold service life, and improving production efficiency and product stability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-5 This utility model provides a technical solution: a stamping die for an air conditioner front cover with a chamfering function, including a lower template 1 and an upper template 2. A chamfering die 11 is fixedly installed on the upper surface of the lower template 1, and a forming chamber 111 is provided inside the chamfering die 11. A chamfering punch 21 is fixedly installed on the bottom surface of the upper template 2, so that when the air conditioner front cover blank is stamped, the chamfering punch 21 can accurately enter the forming chamber 111 and cooperate with the chamfering die 11 to squeeze the edge of the blank, directly completing the chamfering, avoiding traditional secondary processing, improving production efficiency, and ensuring the consistency of the chamfer shape and size.

[0031] In this embodiment, a lower groove 12 is provided on the bottom wall of the molding chamber 111. A cylindrical hole 121 penetrating the lower template 1 is provided at the center of the bottom wall of the lower groove 12. A first cylinder 14 is provided below the lower template 1. An ejector plate 15 is detachably installed at the end of the telescopic shaft of the first cylinder 14. The ejector plate 15 is located in the lower groove 12 and is slidably connected to the lower groove 12. After the stamping is completed, the first cylinder 14 drives the ejector plate 15 to move upward along the lower groove 12, and smoothly ejects the molded air conditioner front cover from the molding chamber 111. This structure makes the demolding process smoother, reduces damage to the surface of the front cover, and improves the product qualification rate.

[0032] Specifically, an annular groove 22 is provided at the center of the bottom surface of the guide angle punch 21, and an inner slide 23 penetrating the upper template 2 is provided at the center of the top wall of the annular groove 22. A third cylinder 25 is fixedly installed on the top surface of the upper template 2. An ejector plate 252 is detachably installed at the end of the telescopic shaft of the third cylinder 25. The ejector plate 252 is located in the annular groove 22 and is slidably connected to the annular groove 22. After the stamping is completed, the third cylinder 25 drives the ejector plate 252 to move downward along the annular groove 22, and smoothly pushes out the front cover plate that may stick to the guide angle punch 21, thus completing the demolding operation.

[0033] like Figure 1As shown, multiple guide posts 10 are fixedly installed on the upper surface of the lower template 1, and multiple guide holes 20 are provided on the upper template 2. The guide posts 10 pass through the guide holes 20 and slide between them, so that the upper template 2 can slide precisely along the guide posts 10 during the stamping process and accurately align with the lower template 1. This effectively ensures the fitting accuracy of the guide angle punch 21 and the guide angle die 11, improves the accuracy of the stamping and guide angle forming of the air conditioner front cover, and reduces the scrap rate.

[0034] In addition, the dimensions of the guide punch 21 are matched with the dimensions of the forming chamber 111, the dimensions of the ejector plate 15 are matched with the dimensions of the lower groove 12, and the dimensions of the ejector plate 252 are matched with the dimensions of the annular groove 22, so that the components can fit together tightly during the stamping process, ensuring the stability of stamping and demolding operations, preventing the product precision from decreasing due to excessive gaps, or the component wear caused by excessive gaps, and extending the service life of the mold.

[0035] like Figure 4 As shown, multiple positioning holes 13 are provided on the bottom wall of the lower groove 12, and multiple guide rods 151 are fixedly installed on the bottom surface of the ejector plate 15. The guide rods 151 are located in the positioning holes 13 and are slidably connected to the positioning holes 13, so that the guide rods 151 always slide in the positioning holes 13 during the up and down movement of the ejector plate 15, accurately guiding the movement of the ejector plate 15, avoiding the ejector plate 15 from shifting during the ejection process, ensuring that the air conditioner front cover can be ejected smoothly and accurately, and improving the demolding quality.

[0036] like Figure 4 As shown, a steel plate 141 is fixedly installed at the end of the telescopic shaft of the first cylinder 14. The ejector plate 15 is detachably installed on the top surface of the steel plate 141 by multiple fastening bolts, so that the ejector plate 15 can be quickly disassembled and replaced after wear or damage, which facilitates the maintenance and upkeep of the mold, reduces maintenance costs, and ensures the normal operation of the ejection function.

[0037] like Figure 3 As shown, a fixed plate 251 is fixedly installed at the end of the telescopic shaft of the third cylinder 25. The ejector plate 252 is detachably installed on the bottom surface of the fixed plate 251 by multiple fastening bolts, which makes it easy to replace the ejector plate 252 when it malfunctions or wears out, improves the maintainability of the mold, ensures the reliability of the demolding process of the upper mold plate 2, and extends the overall service life of the mold.

[0038] It is worth noting that two symmetrical second cylinders 24 are set above the upper template 2. Bolt plates 241 are fixedly installed at the ends of the telescopic shafts of the second cylinders 24. The upper template 2 can be detachably installed on the bottom surface of the two bolt plates 241 by multiple fastening bolts, making the installation and disassembly of the upper template 2 more convenient and facilitating the debugging, maintenance and replacement of parts of the mold. At the same time, the second cylinders 24 can drive the upper template 2 to move, realizing the opening and closing of the mold.

[0039] It is worth noting that a blower 3 is provided on one side of the guide angle die 11 and the guide angle punch 21. A fan 32 is fixedly installed at the air inlet end of the blower 3, and two symmetrical blower pipes 30 are fixedly installed at the air outlet end of the blower 3. A blower chamber 31 is provided inside the blower pipe 30. The air outlet of the blower chamber 31 faces the guide angle die 11 and the guide angle punch 21, so that the airflow generated by the fan 32 is blown out from the air outlet of the blower pipe 30 through the blower chamber 31, which quickly dissipates heat from the guide angle die 11 and the guide angle punch 21. After each stamping, the mold temperature is reduced in time, reducing mold deformation and wear caused by high temperature, improving the service life of the mold, and preparing for the next stamping, thereby improving production efficiency.

[0040] Finally, it should be noted that the components involved in this utility model, such as the first cylinder 14, the third cylinder 25, and the second cylinder 24, are all general standard parts or parts known to those skilled in the art. Their structures and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. In the spare parts of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and the matching controller and power supply, are connected by wires. The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0041] When using the air conditioner front cover stamping die with chamfer forming function, the air conditioner front cover blank is first placed on the lower template 1. Then, the left and right symmetrical second cylinders 24 are started to drive the upper template 2 to move downward along the guide post 10, so that the upper template 2 slides with the guide post 10 through the guide hole 20 until the chamfer punch 21 accurately enters the forming chamber 111 of the chamfer die 11, and the edge of the blank is squeezed and deformed to complete the chamfer forming and stamping forming.

[0042] After stamping is completed, the second cylinder 24 retracts, and at the same time the first cylinder 14 is activated. Its telescopic shaft pushes the ejector plate 15, which moves upward along the lower groove 12 to smoothly eject the formed air conditioner front cover from the forming chamber 111. Meanwhile, the third cylinder 25 drives the ejector plate 252 to move downward along the annular groove 22 to push out the front cover that may stick to the guide angle punch 21, thus achieving demolding.

[0043] After demolding, the fan 32 at the air inlet of the blower 3 is started. The airflow passes through the air chamber 31 of the blower pipe 30 and blows out from the air outlet to quickly dissipate heat from the guide corner die 11 and the guide corner punch 21. After heat dissipation is completed, the second cylinder 24 is started again to drive the upper template 2 to rise, ready for the next stamping operation.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
