Description

Technical Field

[0001] This utility model relates to the field of molding die technology, and in particular to a general mold for molding a semi-circular heat insulation cover. Background Technology

[0002] For semi-circular heat insulation cover products, the traditional molding process involves first cutting the material according to the target size, then rolling the sheet material into a circle using a rolling equipment, and finally using a forming mold to shape the two sides of the rolled material into the target shape, such as... Figures 1 to 3 As shown. Existing molding dies are as follows. Figure 4 As shown, the rolled material is placed on the pressure block 1', and the forming blocks 2' on both sides of the pressure block 1' and the upper punch 3' cooperate to form the target shape.

[0003] However, Figure 4 Due to the size limitations of the pressure block 1', forming block 2' and upper punch 3', the forming mold can only be adapted to specific heat insulation cover lengths. It cannot be used universally for heat insulation covers with the same radius but different lengths, resulting in high mold costs. Utility Model Content

[0004] Based on the above problems, the purpose of this utility model is to provide a universal mold for forming a semi-circular heat insulation cover. By optimizing the mold structure and adjusting the forming method, heat insulation covers of different lengths can be formed by a single mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A general-purpose mold for forming a semi-circular heat insulation cover includes an upper mold plate and a lower mold plate. A fixing plate is provided on the upper mold plate, and a forming punch and a pressure block floating relative to the forming punch are provided on the fixing plate. A forming die is provided on the lower mold plate, and a cavity area and supporting surfaces located on both sides of the cavity area are provided on the forming die. The workpiece to be formed is placed on the supporting surface on either side, with both ends of the workpiece positioned in the cavity area. The workpiece is pressed by the pressure block, and the end of the workpiece in the cavity area is formed by the cooperation of the forming punch and the cavity area.

[0007] As an alternative, brackets are provided on the lower template and on both sides of the forming cavity. The brackets are used to support the end of the workpiece that is away from the cavity area.

[0008] As an alternative, a spring is provided between the fixed plate and the pressure block, an inner guide post is provided on the pressure block that extends into the fixed plate, and an inner guide sleeve that mates with the inner guide post is provided on the fixed plate.

[0009] As an optional solution, one of the upper and lower templates is provided with an outer guide post, and the other of the upper and lower templates is provided with an outer guide sleeve that mates with the outer guide post.

[0010] As an optional solution, limit posts are provided on both the upper and lower mold plates, and the limit posts of the upper mold plate abut against the limit posts of the lower mold plate when the mold is closed.

[0011] As an optional solution, a lower support plate is provided below the lower template, and a pad is provided between the lower support plate and the lower template.

[0012] The beneficial effects of this utility model are:

[0013] The universal mold for forming a semi-circular heat shield features a mold-closing surface that differs from the previous one-time forming process. This allows the two ends of the heat shield to be formed in stages. Since the forming area remains constant, the two-stage forming can be carried out on the same mold, making it suitable for heat shields of various lengths and highly versatile.

[0024] The present invention 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 present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0025] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0027] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] Furthermore, the terms "first" and "second" are merely used to distinguish between different terms in description and do not have any special meaning.

[0029] Please see Figure 5As shown, this embodiment provides a universal mold for forming a semi-circular heat insulation cover, including an upper mold plate 1 and a lower mold plate 2. A fixing plate 3 is provided on the upper mold plate 1, and a forming punch 4 and a pressure block 5 floating relative to the forming punch 4 are provided on the fixing plate 3. A forming die 6 is provided on the lower mold plate 2, and a cavity area 7 and supporting surfaces 8 located on both sides of the cavity area 7 are provided on the forming die 6. The workpiece to be formed is placed on the supporting surface 8 on either side, so that both ends of the workpiece are in the cavity area 7. The workpiece is pressed by the pressure block 5, and the end of the workpiece in the cavity area 7 is formed by the forming punch 4 cooperating with the cavity area 7.

[0030] Therefore, a mold-jointing surface was designed that differs from the previous one-step molding process, allowing the two ends of the heat shield to be formed in stages. Since the forming area remains constant, both stages of forming can be performed on the same mold, making it suitable for heat shields of various lengths and highly versatile. In addition, the supporting surfaces 8 on both sides of the cavity area 7 mean that two sets of workpieces can be formed at one end simultaneously.

[0031] Optionally, a bracket 9 is provided on the lower template 2 and on both sides of the forming cavity 6. The bracket 9 is used to support the end of the workpiece away from the cavity area 7.

[0032] Therefore, the bracket 9 effectively supports the workpiece that is too long, ensuring that workpieces of different lengths can remain stable during the forming process, thereby guaranteeing the processing quality.

[0033] Optionally, a spring 10 is provided between the fixing plate 3 and the pressure block 5, an inner guide post 11 extending into the fixing plate 3 is provided on the pressure block 5, and an inner guide sleeve 12 cooperating with the inner guide post 11 is provided on the fixing plate 3.

[0034] Thus, the spring 10 provides elastic force, causing the pressure block 5 to float relative to the forming punch 4. The precise cooperation between the inner guide post 11 and the inner guide sleeve 12 further improves the movement accuracy of the pressure block 5, so that the part of the workpiece located outside the front cavity area 7 during forming is pressed down, ensuring that the workpiece does not move during the forming process.

[0035] Optionally, one of the upper template 1 and the lower template 2 is provided with an outer guide post 13, and the other of the upper template 1 and the lower template 2 is provided with an outer guide sleeve 14 that cooperates with the outer guide post 13.

[0036] Therefore, the precise cooperation between the outer guide post 13 and the outer guide sleeve 14 ensures the movement accuracy of the upper template 1 relative to the lower template 2, guaranteeing stability and product quality consistency during the mold opening and closing process.

[0037] Optionally, limit posts 15 are provided on the upper mold plate 1 and the lower mold plate 2 respectively. When the mold is closed, the limit posts 15 of the upper mold plate 1 abut against the limit posts 15 of the lower mold plate 2. Thus, by precisely limiting the upper and lower mold plates 15, the mold closing clearance is controlled according to the workpiece thickness, avoiding excessive mold closing.

[0038] Optionally, a lower support plate 16 is provided below the lower template 2, and a pad 17 is provided between the lower support plate 16 and the lower template 2.

[0039] Therefore, by adjusting the height of the lower template 2 using the pad 17, it is ensured that the mold and workpieces of different heights can be accurately aligned, further improving molding accuracy and product quality.

[0040] Based on this universal mold for forming a semi-circular heat insulation cover, the original process can be improved, especially by dividing the forming process into two steps. The first step is to form one end of the workpiece, such as... Figure 6 As shown; the other end of the workpiece formed in the second step, as... Figure 7 As shown, since the concave cavity region 7 remains unchanged, the two-step molding can be produced on the same set of molds, and the two sets of workpieces can be produced simultaneously. Most importantly, it can be used to produce heat shields of different lengths on this semi-circular heat shield molding universal mold, which improves the versatility of the mold and reduces the mold cost.

[0041] Detailed operation process:

[0042] 1) In the initial mold opening state, the pressure block 5 is lifted by the spring 10; the outer guide post 13 and the outer guide sleeve 14 are in a separated state; the pressure block 5 and the forming die 6 have not yet come into contact; one end of the workpiece to be formed is placed in the cavity area 7 of the forming die 6. In addition, for longer workpieces, part of the workpiece will be placed on the bracket 9.

[0043] 2) During the mold closing process, as the upper mold plate 1 moves downward, the outer guide post 13 and the outer guide sleeve 14 begin to contact and guide. Then the pressure block 5 presses down on the workpiece, the spring 10 begins to compress and provide pressure, the forming punch 4 continues to move downward, and forming begins.

[0044] 3) The upper template 1 continues to move until the upper and lower limit posts 15 contact each other, and the mold closes;

[0045] 4) During the mold opening process, the spring 10 returns to its original position, and the workpiece with the corresponding end formed is pushed out by the pressure block 5;

[0046] 5) Move the unformed end of the workpiece to the cavity area 7, close the mold again, and complete the forming of both ends of the workpiece step by step.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
