[0034] Embodiment 1

[0035] As Figures 1-4This embodiment provides a continuous mold for bending sheet metal at both ends of an air conditioner, including an upper clamping plate, an upper stripper assembly 1, a lower template assembly 2, a lower pad plate, and a feeding component. The feeding component is located between the upper stripper assembly 1 and the lower template assembly 2.

[0036] The upper ejector plate assembly 1 includes a bending upper ejector plate 11, a stretching upper ejector plate 12, a shaping upper ejector plate 13, a rib-pressing upper ejector plate 14, a punching upper ejector plate 15, a trimming upper ejector plate 16, and a bending demolding upper ejector plate 17 connected in sequence; the lower template assembly 2 includes a bending lower template 21, a stretching lower template 22, a shaping lower template 23, a rib-pressing lower template 24, a punching lower template 25, a trimming lower template 26, and a bending demolding lower template 27 connected in sequence; the bending lower template 21 is located at the end of the upper ejector plate assembly 1 near the feed inlet;

[0037] The upper stripper plate 11 for bending corresponds vertically to the lower template 21 for bending; the upper stripper plate 12 for stretching corresponds vertically to the lower template 22 for stretching; the upper stripper plate 13 for shaping corresponds vertically to the lower template 23 for shaping; the upper stripper plate 14 for pressing ribs corresponds vertically to the lower template 24 for pressing ribs; the upper stripper plate 15 for punching corresponds vertically to the lower template 25 for punching; the upper stripper plate 16 for trimming corresponds vertically to the lower template 26 for trimming; and the upper stripper plate 17 for bending demolding corresponds vertically to the lower template 27 for bending demolding.

[0038] Working principle: The feeding component conveys the raw material to be processed between the upper stripper group 1 and the lower template group 2. It passes through the bending upper stripper 11 and bending lower template 21 to bend one end of the material in sequence. The stretching upper stripper 12 and stretching lower template 22 perform preliminary stretching of the material in a localized area. The shaping upper stripper 13 and shaping lower template 23 perform fine-tuning of the dimensions of the preliminary stretched part. The reinforcing upper stripper 14 and reinforcing lower template 24 perform reinforcing rib punching on the bent part of the part. After punching and trimming, the bending demolding upper stripper 17 and bending demolding lower template 27 bend the other end of the part and demold the processed part.

[0039] The bending process is first performed by bending the upper stripper plate 11 and bending the lower template 21. Then, the upper stripper plate 14 and the lower template 24 are used to press the reinforcing ribs on the bent part. This avoids the situation where the bending force is greater after the ribs are pressed on the bent part, and there is also the situation where the reinforcing ribs are deformed and additional structural adjustments are required. This simplifies the mold structure. Moreover, during demolding, the other end of the sheet metal is bent in conjunction with the demolding structure. This avoids the situation where both ends are bent at the same time and stuck on the lower template. This eliminates the need for unnecessary part lifting structures on the lower template, further simplifying the mold structure, improving the part processing efficiency, and reducing costs after simplifying the mold structure.

[0040] In a preferred embodiment, the upper demolding plate 17 for bending and demolding is provided with a bending punch, and the lower demolding plate 27 for bending and demolding is provided with an inclined step, with the bending punch and the inclined step corresponding vertically.

[0041] Furthermore, the lower die plate 27 for bending and demolding is equipped with elastic ejector blocks. There are multiple elastic ejector blocks, symmetrically distributed at both ends of the sheet. The shape of each ejector block is adjusted according to the structure of the sheet to ensure effective contact between the ejector block and the sheet, preventing deformation of the sheet.

[0042] The lower bending template 21 is equipped with a return spring, which corresponds vertically to the position of the bent portion of the plate. By setting the return spring below the bent portion of the plate, the bent portion can be pushed out and smoothly transferred to the next lower template.

[0043] Specifically, a guide post is provided between the upper clamping plate and the lower pad. The lower pad is provided with a guide post sleeve, and the guide post passes through the guide post sleeve.

[0044] Meanwhile, the mold also includes an upper mold base and a lower mold base, with a guide column between the upper mold base and the lower mold base, and a spring sleeved on the guide column.

[0045] The guide pillars between the upper clamping plate and the lower pad limit the relative movement direction of the upper ejector plate and the lower template. The guide pillars, together with the guide outer pillars, guide the relative movement direction between the upper mold base and the lower mold base, thereby improving the machining accuracy between each upper ejector plate and the corresponding lower template. The springs on the guide outer pillars can assist in the separation of the upper template and the lower template, saving energy.

[0046] Specifically, the upper mold base is equipped with a first limiting platform, and the lower mold base is equipped with a second limiting platform, with the positions of the first and second limiting platforms corresponding vertically. This limits the stroke between the upper and lower mold bases to prevent excessive extrusion and deformation of the sheet metal.

[0047] The lower mold base has a guide frame near the feeding component. The guide frame is movably mounted on the lower mold base, and an adjusting spring is provided between the guide frame and the lower mold base. The guide frame can adapt to mold closing and opening, avoiding additional forces on the sheet metal and improving the accuracy of sheet metal forming.

[0048] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
