Description

Technical Field

[0001] This application belongs to the technical field of pressure casting, and particularly relates to a support frame and nozzle. Background Technology

[0002] In recent years, die casting technology has been widely used in the manufacturing of new energy vehicles. With the advancement of die casting technology and die casting machine manufacturing technology, the size of parts that can be directly cast by die casting is increasing day by day. For example, large new energy vehicle parts such as the front engine compartment, rear floor, and battery casing can be formed in one piece by die casting, which greatly improves the overall strength of the parts and reduces assembly costs. However, the increase in the size of die-cast parts also brings challenges to the design of spraying solutions.

[0003] Currently, the two main types of spraying solutions commonly found in the industry are modular and frame-type structures. Modular spraying solutions consist of multiple spray plates assembled together. Their advantages include high material standardization, flexibility, ease of adjustment, and aesthetically pleasing appearance. However, they are heavy, have low rigidity, and are prone to damage from minor impacts, leading to nozzle seal failure and leakage. Furthermore, nozzle restoration is difficult. Frame-type spraying solutions result in a box-like structure, characterized by light weight, less machining, and high strength. Their drawbacks include excessive height and length, a completely enclosed structure, the need for the nozzle to be close to the high-temperature mold during spraying, and difficulty in adjusting the angle and flow rate of the top and middle atomizers.

[0004] In summary, the current spraying solution is structurally inadequate to meet current usage requirements, presents numerous inconveniences, and has limited applicability. Utility Model Content

[0005] In view of this, embodiments of this application provide a support frame and a nozzle to solve the technical problems that existing spraying solutions have structures that are difficult to meet current usage requirements, have many inconveniences, and have low applicability.

[0006] Firstly, embodiments of this application provide a support framework, including:

[0007] Support plate;

[0008] At least two first connecting rods are spaced apart along a first direction, and the first connecting rods are connected to the support plate;

[0009] A plurality of second connecting rods are respectively connected to the first connecting rod, wherein at least two of the second connecting rods are spaced apart along a second direction;

[0011] A mounting plate is provided along a first aspect and / or a second direction, the mounting plate being used to mount nozzles and / or air nozzles;

[0012] The first connecting rod, the second connecting rod, the fixed rod, and the mounting plate are cross-connected and form a clearance space.

[0013] In some embodiments, the mounting plate is disposed along the edge and / or center of the support frame to form the clearance space at a position near the center of the support frame.

[0014] In some embodiments, a portion of the mounting plate is located at the end of the first connecting rod, and the mounting plate is connected to the second connecting rod.

[0015] In some embodiments, a portion of the mounting plate is located in the middle of the first connecting rod, and the mounting plate is connected to the second connecting rod.

[0016] In some embodiments, a portion of the mounting plate is disposed at the end of the second connecting rod.

[0017] In some embodiments, the fixing rods disposed at both ends of the support plate have their other ends connected to the end of the first connecting rod.

[0018] In some embodiments, the end of the fixing rod away from the support plate is further provided with a reinforcing rod, and the other end of the reinforcing rod is connected to the first connecting rod or the second connecting rod.

[0019] In some embodiments, the fixing rod disposed in the middle of the support plate has its other end connected to the middle of the first connecting rod.

[0020] In some embodiments, the fixed rod has a reinforcing member at its end and a reinforcing rod at its middle, the reinforcing rod connecting the fixed rod and the first connecting rod.

[0021] In some embodiments, a reinforcing member is provided at the connection between the first connecting rod and the second connecting rod.

[0022] Secondly, an embodiment of this application provides a nozzle, comprising:

[0023] The supporting framework described in the first aspect;

[0024] The nozzle is detachably mounted on the mounting plate;

[0025] The air nozzle is detachably mounted on the mounting plate;

[0026] A control valve, mounted on the support plate, is used to control the operation of the nozzle and / or the air inlet.

[0027] In some embodiments, a mounting flange is provided at the center of the support plate for connecting to the robotic arm, and the control valve is located on both sides of the mounting flange.

[0028] In some embodiments, the mounting plate on which the air nozzle is mounted has an air inlet on the side of the mounting plate away from the air nozzle;

[0029] The mounting plate on which the nozzle is mounted has a spray medium inlet on the side of the mounting plate away from the nozzle.

[0030] The support frame and nozzle provided in this application embodiment, through the cross-arranged first connecting rod, second connecting rod and fixing rod, form a clearance space, making the entire support frame hollow. In this way, the weight of the entire support frame is effectively reduced, solving the problems of insufficient rigidity, heavy weight of modular nozzles and inconvenient adjustment of frame-type nozzles. Moreover, due to the lightweight of the overall structure, more nozzles and control valves can be arranged in the nozzle layout, the spray can achieve more comprehensive contouring, meet the precise control of the contouring structure, improve the spraying effect on the mold, shorten the die casting cycle and reduce the consumption of release agent.

The above description is for the purpose of understanding the technical solution of this application and should not be construed as a limitation on the protection scope of the embodiments of this application.

[0053] The first aspect of this application provides a support frame 10, such as... Figures 1 to 4 As shown, the support frame 10 includes a support plate 11, at least two first connecting rods 12, a plurality of second connecting rods 13, at least two fixing rods 14, and a mounting plate 15;

[0054] At least two first connecting rods 12 are spaced apart along a first direction, and the first connecting rods 12 are connected to the support plate 11;

[0055] Multiple second connecting rods 13 are respectively connected to the first connecting rod 12, wherein at least two second connecting rods 13 are spaced apart along the second direction;

[0056] One end of the fixing rod 14 is connected to the support plate 11, and the other end of the fixing rod 14 is connected to the first connecting rod 12. An angle is formed between the fixing rod 14 and the first connecting rod 12.

[0057] Mounting plate 15 is disposed along a first direction and / or a second direction, and mounting plate 15 is used to mount nozzle 20 and / or air nozzle 30;

[0058] The first connecting rod 12, the second connecting rod 13, the fixing rod 14, and the mounting plate 15 are interconnected to form a clearance space 100. This creates a hollow support frame, which helps reduce the overall weight of the support frame 10 and the nozzle, and allows for the placement of more nozzles 20 on the support frame 10, thus achieving a better spraying solution. The hollow structure allows maintenance personnel to easily adjust the nozzles 20 from the mold-closed surface, and also provides a more direct view of the nozzle outlet's spray position and spray effect, saving time during debugging and maintenance.

[0059] The support frame 10 provided in this embodiment forms a clearance space 100 through the cross-arranged first connecting rod 12, second connecting rod 13, and fixing rod 14, making the entire support frame 10 hollow. In this way, the weight of the entire support frame 10 is effectively reduced, solving the problems of insufficient rigidity, heavy weight, and inconvenient adjustment of frame-type nozzles. Moreover, due to the lightweight overall structure, more nozzles 20 and control valves 40 can be arranged in the nozzle layout, and the spray can achieve more comprehensive contouring, meet the precise control of the contouring structure, improve the spraying effect on the mold, shorten the die-casting cycle, and reduce the consumption of release agent.

[0060] In applications, such as Figure 1 As shown, the end where the support plate 11 is located is the top. The support plate 11 is connected to the first connecting rod 12 and the fixing rod 14. The ends of the first connecting rod 12 and the fixing rod 14 are fixed by connectors. Furthermore, connecting ribs are provided on the side of the support plate 11 for reinforcement. In specific embodiments, the connectors include, but are not limited to, screws, rivets, etc., and the shape of the connecting ribs includes quadrilaterals, triangles, etc. Using triangular connecting ribs is beneficial to improving stability. The fixing rod 14 is provided to facilitate the fixing of the support plate 11, so as to facilitate the subsequent installation of other components on the support plate 11.

[0061] In applications, such as Figure 1As shown, at least two first connecting rods 12, multiple second connecting rods 13, and at least two fixing rods 14 are provided. Thus, the first connecting rods 12 and second connecting rods 13 form a hollow frame. One end of the fixing rod 14 is connected to one end of the first connecting rod 12, and the other end is positioned along the length of the first connecting rod 12, forming an angle between them. This creates a triangular hollow support structure between the fixing rod 14, the first connecting rod 12, and the support plate 11, making the entire support frame 10 lighter while improving its stability. Furthermore, the first connecting rods 12 and second connecting rods 13 are arranged perpendicularly to each other. This facilitates the formation of a regularly shaped clearance space 100 (i.e., a hollow structure). The hollow structure allows maintenance personnel to easily adjust the nozzles 20 on the mounting plate 15 from the mold-closed surface, and also provides a more direct view of the nozzle outlet's spray position and spray effect, saving maintenance time.

[0062] In a preferred embodiment, four first connecting rods 12 are provided, spaced apart and parallel to each other along a first direction. This facilitates production and results in a more rational structural layout. In other embodiments, the first connecting rods 12 may not be arranged in parallel. Four fixing rods 14 are provided, the same number as the first connecting rods 12, and are arranged in the same manner as the first connecting rods 12, forming a triangular hollow support structure between the fixing rods 14, the first connecting rods 12, and the support plate 11. This helps reduce the overall weight of the support frame 10 and improves the stability of the support.

[0063] In application, the mounting plate 15 includes a spray plate 152 and a nozzle 30 plate 153. The spray plate 152 is used to mount the nozzles 20, and the nozzle 30 plate 153 is used to mount the nozzles 30. The mounting plate 15 can be arranged along the length of the first connecting rod 12 or along the length of the second connecting rod 13. In a specific embodiment, the spray plate 152 and the nozzle 30 plate 153 can also be arranged side by side in pairs, so that more nozzles 20 and nozzles 30 can be arranged on the support frame 10 to meet different spraying needs. Thus, the entire row of spray plates 152 can be adjusted in the first and second directions, or the number of spray plates 152 and nozzles 20 can be increased or decreased according to changes in the site. Assembly is simple and adjustment is highly flexible.

[0064] In some embodiments, such as Figure 1As shown, the mounting plate 15 is disposed along the edge and center of the support frame 10 to form a clearance space 100 near the center of the support frame 10. In other embodiments, the mounting plate 15 is disposed along the edge of the support frame 10, or along the center of the support frame 10. This allows maintenance personnel to easily adjust the nozzles 20 on the mounting plate 15 from the mold-closing surface, and also provides a more intuitive view of the nozzle outlet's spray position and spray effect, saving maintenance time.

[0065] In some embodiments, such as Figure 1 As shown, a portion of the mounting plate 15 is located at the end of the first connecting rod 12 and is connected to the second connecting rod 13; a portion of the mounting plate 15 is located in the middle of the first connecting rod 12 and is connected to the second connecting rod 13; a portion of the mounting plate 15 is located at the end of the second connecting rod 13. In other embodiments, a portion of the mounting plate 15 is located at the end of the first connecting rod 12 and a portion of the mounting plate 15 is located at the end of the second connecting rod 13. In other embodiments, a portion of the mounting plate 15 is located at the end of the first connecting rod 12, or a portion of the mounting plate 15 is located at the end of the second connecting rod 13. In other words, the multiple mounting plates 15 are arranged in a U-shape, a square shape, or a sun shape. This forms a hollow structure, facilitating adjustment of the nozzles 20 on the mounting plate 15 by maintenance personnel from the mold-closed face.

[0066] In some embodiments, fixing rods 14 are disposed at both ends of the support plate 11, with the other end of the fixing rod 14 connected to the end of the first connecting rod 12. That is, the fixing rods 14, the first connecting rod 12, and the support plate 11 form a triangular support structure located at the edge of the entire support frame 10. Further, as... Figure 2 As shown, a reinforcing rod 16 is also provided at the end of the fixing rod 14 away from the support plate 11, and the other end of the reinforcing rod 16 is connected to the first connecting rod 12 or the second connecting rod 13. This further improves the overall stability of the support frame 10.

[0067] In some embodiments, a fixing rod 14 is disposed in the middle of the support plate 11, and the other end of the fixing rod 14 is connected to the middle of the first connecting rod 12 or the second connecting rod 13. In this way, the length of the fixing rod 14 can be reduced, thereby reducing the overall weight and making the support frame 10 lighter.

[0068] In some embodiments, the end of the fixing rod 14 is provided with a reinforcing member 17, and the middle of the fixing rod 14 is provided with a reinforcing rod 16, which connects the fixing rod 14 and the first connecting rod 12. The reinforcing member 17 includes, but is not limited to, a connecting stiffener. In other embodiments, the connection between the first connecting rod 12 and the second connecting rod 13 is provided with a reinforcing member 17. This is beneficial for further reinforcing the support stability of the support frame 10.

[0069] In some embodiments, the first connecting rod 12, the second connecting rod 13, the fixing rod 14, and the reinforcing rod 16 are all made of standard profiles. For example... Figure 3 As shown, the standard profile has multiple openings 101 and multiple slots 102 inside, which ensures the overall mechanical strength while achieving the greatest lightweight design and facilitating assembly and design.

[0070] In some embodiments, the mounting plate 15 uses a custom profile, such as Figure 4 As shown, the custom-designed profile has internal fixing holes 150 and multiple dedicated channels 151. This ensures overall mechanical strength while achieving maximum lightweight design and facilitating assembly and design. The frame is constructed using standard aluminum profiles, and the nozzle 20 spray plate 152 is made of custom aluminum profiles. This ensures the rigidity of the large-size nozzle while achieving overall structural lightweighting. Furthermore, the extensive use of standard aluminum profiles and standard profile connectors significantly reduces processing costs and raw material waste.

[0071] This application also provides a nozzle, such as... Figure 5 and Figure 6 As shown, it includes a support frame 10, a nozzle 20, an air nozzle 30, and a control valve 40;

[0072] The nozzle 20 is detachably mounted on the mounting plate 15;

[0073] The air nozzle 30 is detachably mounted on the mounting plate 15;

[0074] The control valve 40 is mounted on the support plate 11 and is used to control the operation of the nozzle 20 and the air nozzle 30.

[0075] The nozzle provided in this application embodiment, because it adopts the support frame 10 described in the first aspect, allows the entire nozzle to adjust the row of spray plates 152 (mounting plate 15) in the first and second directions, or to increase or decrease the spray plates 152 and nozzles 20 according to changes on site. It is simple to assemble and highly flexible in adjustment. Due to the lightweight overall structure, the nozzle can accommodate more nozzles 20 and control valves 40, enabling more comprehensive contouring of the spray, meeting the precise control of the contouring structure, improving the coating effect of the mold, shortening the die-casting cycle, and reducing the consumption of release agent.

[0076] In some embodiments, such as Figure 5 As shown, a mounting flange 50 is also provided in the middle of the support plate 11. The mounting flange 50 is used to connect with the robotic arm, and the control valve 40 is located on both sides of the mounting flange 50. This facilitates the connection between the nozzle and the robotic arm.

[0077] In some embodiments, such as Figure 6As shown, a mounting plate 15 on which an air nozzle 30 is mounted has an air inlet 60 on the side away from the air nozzle 30; a mounting plate 15 on which a nozzle 20 is mounted has a spray medium inlet 70 on the side away from the nozzle 20. This facilitates the supply of spray medium to the nozzle 20 and compressed air to the air nozzle 30.

[0078] In applications, nozzle 30 includes, but is not limited to, an extended 90-degree straight nozzle, a powerful flat nozzle, and a standard nozzle. Nozzle 20 includes, but is not limited to, a standard straight nozzle and an extended nozzle. Using different types of nozzles 20 and nozzles 30 allows the spray head to be adapted to different spraying needs.

[0079] In the above embodiments, the descriptions of each embodiment have different focuses. For parts that are not described in detail or recorded in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0080] The above-described embodiments are only used to illustrate the technical solutions of the embodiments of this application, and are not intended to limit them. Although the embodiments of this application have been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
