[0038] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0039] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0040] like Figures 1 to 5 As shown, this utility model discloses a hot-press coating mold structure assembly that can reduce local stress, used to bond fabric 10 to a frame 11. It includes: a worktable 2; a contouring seat 20 and a pressing mechanism 3, both mounted on the worktable 2. The pressing mechanism 3 can press the fabric 10 to restrict its movement when the contouring seat 20 receives the fabric 10; and a punching mechanism 4, mounted on the side wall of the contouring seat 20, equipped with several punching blades 40 for cutting the fabric 10 to release it. 0. Stress generated during reverse edge wrapping; upper mold mechanism 5 and hot pressing mechanism 6, the upper mold mechanism 5 is movably set above the contouring seat 20, the skeleton 11 can be vacuum adsorbed onto the bottom wall of the upper mold mechanism 5; the hot pressing mechanism 6 can be movably extended between the upper mold mechanism 5 and the contouring seat 20 to realize synchronous heating of the skeleton 11 and the fabric 10; the punching blade 40 can punch out the position of the fabric 10 to release stress when the upper mold mechanism 5 closes and wraps the contouring seat 20, so that the fabric 10 can be tightly bonded to the skeleton 11 after reverse edge wrapping.

[0041] Due to the location of the radius (R) of the part's shape (see reference) Figure 2 The rounded corners of the skeleton 11 (not shown in the figure) have a large reverse edge. In this embodiment, it is necessary to ensure that the fabric 10 will not tear during the reverse edge wrapping operation. Specifically, the fabric 10 to be wrapped is placed on the contour seat 20 to ensure its accurate position. As the pressing mechanism 3 moves to press the fabric 10, it effectively limits unnecessary movement in subsequent operations, thereby ensuring the stability of the fabric 10 during hot pressing and avoiding quality problems caused by displacement. At the same time, the skeleton 11 is fixed to the bottom wall of the upper mold mechanism 5 by vacuum adsorption (a vacuum suction cup or vacuum pump can be used, not shown in the figure) (i.e., the position of the skeleton 11 to be wrapped faces the fabric 10), ensuring that the skeleton 11 will not move during hot pressing. Before the mold closing and wrapping operation begins, the fabric 10 and the skeleton 11 need to be heated to activate the hot melt adhesive. Therefore, the hot pressing mechanism 6 can be powered by... Figure 1 The position shown is moved between the upper mold mechanism 5 and the contouring seat 20, thereby synchronously heating the skeleton 11 and the fabric 10 to achieve ideal bonding temperature conditions and ensure good adhesion between the skeleton 11 and the fabric 10. After the required temperature is reached, the hot pressing mechanism 6 returns to its original position. Figure 1 As shown, at the position indicated, the upper mold mechanism 5 drives the skeleton 11 and the contour seat 20 to perform a mold closing and wrapping action. It should be noted that after the mold closing and wrapping, before the skeleton 11 and the fabric 10 achieve reverse edge wrapping, the punching mechanism 4 can drive the punching blade 40 to accurately cut out the position in the fabric 10 where the stress needs to be released (i.e., the position of the fabric 10 corresponding to the R angle of the skeleton 11). This precise operation helps reduce the risk of the fabric 10 tearing due to excessive stress during reverse edge wrapping. After the stress release position is accurately punched, the reverse edge wrapping operation can be performed, making the fabric 10 tightly bonded to the skeleton 11. It can be seen that this solution integrates thermoforming and reverse edge wrapping into one unit, simplifying the production process, reducing the changeover time between processes, and significantly improving production efficiency. At the same time, the addition of the punching blade 40 at the reverse edge wrapping position on the mold effectively avoids the problem of difficulty in fixing the opening position in traditional opening methods, reduces quality problems caused by the fabric 10 tearing or weak bonding, and improves the quality of the final product.

[0042] The punching mechanism 4 also includes a punching cylinder 41 and a tool holder 42. The punching cylinder 41 is mounted on the side wall of the contour base 20. The tool holder 42 is detachably connected to the output end of the punching cylinder 41, and a number of tool slots 420 for mounting the punching blades 40 are provided in the tool holder 42.

[0043] Furthermore, such as Figure 3As shown, by adopting the design of punching cylinder 41 driving tool holder seat 42, accurate control of the punching position is realized, ensuring that each cutting is accurately positioned at the position where stress needs to be released, reducing errors caused by manual operation; and the detachable design of tool holder seat 42 also allows users to easily replace different tool holder seats 42 according to specific needs, which on the one hand helps daily cleaning and maintenance, facilitates timely replacement of worn punching blades 40, ensures long-term stable operation while reducing maintenance costs, and on the other hand adjusts the number and layout of punching blades 40 to meet the processing requirements of different types of products, improving the versatility and application range of the equipment.

[0044] Preferably, as Figure 3 As shown, the end of the punching blade 40 is formed with an inclined surface 400 at an included angle on both sides, and the inclined surfaces 400 on both sides form a sharp part 401 together. The design of the sharp part 401 makes it easier for the punching blade 40 to cut into the fabric 10, reduces the force required for cutting, improves cutting speed and accuracy, and ensures that each cutting is accurately positioned at the position where stress needs to be released. It is also because of the existence of the sharp part 401 that the punching action is more smooth and natural, reducing the risk of damage to the fabric 10 caused by excessive stretching or uneven stress during cutting, ensuring the quality of the fabric 10 and ensuring that the fabric 10 can be stably bonded to the framework 11. It should be noted that the punching blade 40 in this embodiment is not limited to one type in this embodiment, and its punching direction can be adjusted adaptively according to the specifications and characteristics of the actual fabric 10 and framework 11.

[0045] The pressing mechanism 3 comprises a base 30 arranged on the workbench 2, a linear guide rail 31 arranged on the base 30, and a lifting cylinder 32 connected to the output end of the linear guide rail 31, and the moving directions of the linear guide rail 31 and the lifting cylinder 32 are arranged vertically, and the driving end of the lifting cylinder 32 is connected with a profiling pressing block 320, and the profiling pressing block 320 is movably pressed against the fabric 10.

[0046] Further, as Figure 3As shown, with the correct laying of the fabric 10 to be processed on the profiling seat 20, the profiling pre-pressing block can be quickly moved close to the fabric 10 along the direction of the profiling seat 20 by relying on the linear guide rail 31 at this time, and with the driving of the lifting cylinder 32, the profiling pressing block 320 can be pressed downward in the vertical direction after being located above the fabric 10, so as to ensure that the fabric 10 can be uniformly and stably attached to the profiling seat 20, preventing unnecessary movement or wrinkles of the fabric 10 in the subsequent processing process; and under the cooperation of the linear guide rail 31 and the lifting cylinder 32, the structure can be freely adjusted according to fabrics 10 of different shapes and sizes, improving the versatility and flexibility of the mold structure, and whether it is a flat surface or a part with a complex curved surface, effective pressing can be realized, ensuring that the quality of the subsequent process is not affected.

[0047] Further preferably, the profiling pressing block 320 is formed with a avoiding part 320a, which allows the punching blade 40 to accurately penetrate the fabric 10 for punching without interfering with the pressing operation, ensuring that each punching can be accurately positioned to the position where stress needs to be released, improving the accuracy of the operation. That is, it ensures the stable pressing state of the fabric 10 in the entire processing process, and does not hinder the operation of the punching blade 40, which reflects the rationality and efficiency of the structure design, and helps to maintain the integrity and quality of the fabric 10.

[0048] The hot pressing mechanism 6 comprises a mounting frame 60 arranged on the workbench 2, and a moving assembly 61 arranged on the mounting frame 60, wherein the moving assembly 61 comprises a moving frame 610 and a plurality of infrared lamp tubes 611, the moving frame 610 is connected to the driving end of the moving assembly 61, and the plurality of infrared lamp tubes 611 are arrayed and equidistantly distributed on the moving frame 610. When the moving frame 610 moves to the position between the upper die mechanism 5 and the profiling seat 20, the infrared lamp tubes 611 can simultaneously heat the fabric 10 and the framework 11.

[0049] As Figure 1 and Figure 4As shown, when the above fabric 10 is firmly attached to the profiling seat 20, and the skeleton 11 is vacuum adsorbed on the upper die mechanism 5, the moving assembly 61 is started, so that the moving frame 610 and the plurality of infrared lamp tubes 611 are moved to between the upper die mechanism 5 and the profiling seat 20. In this process, the infrared lamp tubes 611 are turned on synchronously, and the fabric 10 placed on the profiling seat 20 and the skeleton 11 on the upper die mechanism 5 are uniformly heated. It should be noted that since the infrared lamp tubes 611 need to heat the surface of the fabric 10 and the skeleton 11 to 150°C within 15s, through the design of the array equidistant distribution of the infrared lamp tubes 611, it ensures that the heat can be uniformly and efficiently transmitted to the fabric 10 and the skeleton 11, reduces the problem of local overheating or insufficient heating, improves the heating efficiency and quality, and saves the production cycle time. That is, the heat emitted by the infrared lamp tubes 611 can quickly penetrate the material surface to achieve rapid and uniform heating effect, so that the fabric 10 and the skeleton 11 reach the ideal bonding temperature condition, and after heating is completed, the mold clamping and covering operation can be performed.

[0050] The moving assembly 61 includes a guide rod 612 and a movable block 613. The guide rod 612 is arranged in parallel with the moving direction of the moving frame 610. The movable block 613 is movably sleeved on the guide rod 612 and connected to the moving frame 610 through a connecting plate 614. The movable block 613 and the moving frame 610 are both connected with a sliding block 615. Both sides of the mounting frame 60 are provided with a sliding rail 616, and the sliding block 615 is movably connected to the sliding rail 616.

[0051] Further, as shown in the drawings, Figure 4 The guide rod 612 is connected with a driving motor (not shown in the drawings). The rotation of the guide rod 612 can drive the movable block 613 to reciprocally slide along the axis direction of the guide rod 612. At the same time, through the structural design of the cooperation of the guide rod 612 and the sliding rail 616, the moving frame 610 has high precision and stability during movement, avoiding the problems of uneven heating or position deviation caused by unstable movement or mechanical vibration, and improving the processing quality. The moving assembly 61 adopts a modular design, which is easy to disassemble and replace. It is not only convenient for daily cleaning and maintenance, but also facilitates timely replacement of worn parts, prolongs the service life, and reduces maintenance costs. It should be noted that the structure and working principle of the guide rod 612 and the movable block 613 in the embodiment are the same as those of the commonly used ball screw in machinery, which will not be described in detail here.

[0052] Preferably, as shown in the drawings, Figure 4As shown, the moving frame 610 is also provided with a plurality of light shielding plates 617. Since the infrared lamp tube 611 generates extremely high brightness due to instantaneous heating, long-time operation of the equipment by the staff can cause damage to the eyes. By adding metal light shielding plates 617 (for example, stainless steel, aluminum alloy, etc.) at the periphery (may be the front section, left / right section) of the infrared lamp tube 611, the heat loss is prevented, the heating efficiency is improved, and the light is effectively blocked, thereby providing a safer working environment for workers.

[0053] Further, as shown in the drawings, Figure 5 As shown, the upper die mechanism 5 includes a clamping cylinder 50 and a movable die block 51. The clamping cylinder 50 is arranged in the vertical direction, and the movable die block 51 is connected to the output end of the clamping cylinder 50. As the clamping cylinder 50 moves downward along the vertical direction, the movement trajectory of the movable die block 51 is ensured to be accurate, thereby realizing accurate butt joint between the framework 11 and the fabric 10, and avoiding quality problems caused by position deviation. Preferably, the same slider 615 and slide rail 616 structure as the above structure can be arranged on one side of the movable die block 51 to further improve the accuracy of the reciprocating movement of the framework 11. It should be noted that the upper die mechanism 5 in the embodiment has the same structure and working principle as the existing hot-pressing and coating forming process, which will not be described here.

[0054] Preferably, the upper die mechanism 5 of the embodiment further includes a plurality of edge pressing blocks 52. During the clamping and coating process, the edge pressing blocks 52 can be movably pressed on the fabric 10, thereby further ensuring the accuracy and stability of the fabric 10 tightly bonded to the framework 11.
