DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present application are only used to explain the relative positional relationship, movement condition, etc. between components in a certain posture (as shown in the drawings), and if the certain posture changes, the directional indications will also change accordingly.

[0037] As Figures 1 to 5As shown, the utility model relates to a hot-pressing coating mold structure assembly with anti-bulging function for bonding fabric on a framework, comprising: a workbench 1, which is provided with a profiling seat 10 for receiving and limiting fabric movement; an upper die mechanism 2 and a hot-pressing mechanism 3, wherein the upper die mechanism 2 is movably arranged above the profiling seat 10, and the framework can be vacuum adsorbed to the bottom wall of the upper die mechanism 2; the hot-pressing mechanism 3 can be movably extended between the upper die mechanism 2 and the profiling seat 10 to realize synchronous heating of the framework and the fabric; a plurality of stretching mechanisms 4, which are distributed at the periphery of the profiling seat 10, each of the stretching mechanisms 4 comprises a telescopic assembly 40 and a cloth hanging assembly 41, the cloth hanging assembly 41 is connected to the driving end of the telescopic assembly 40, and a cloth hanging needle 410 is movably arranged on the cloth hanging assembly 41, and the telescopic assembly 40 is used to drive the fabric to stretch through the cloth hanging needle 410; when the upper die mechanism 2 moves along the profiling seat 10, the cloth hanging needle 410 penetrates the fabric to allow the telescopic assembly 40 to drive the fabric to convey along the profiling seat 10, thereby preventing the fabric from bulging due to rebound after coating forming.

[0038] The embodiment mainly solves the problem of bulging of the part after coating forming when stored at high temperature. Through analysis, it is found that the fabric is stretched to cause rebound at high temperature, and the framework is peeled off to cause bulging. Specifically, as shown, Figures 1 to 3 As shown, the fabric to be processed is placed on the profiling seat 10, and the framework is vacuum adsorbed to the bottom wall of the upper die mechanism 2 (a vacuum chuck or a vacuum pump can be used, not shown in the figure), after everything is ready, the hot-pressing mechanism 3 can be movably extended between the upper die mechanism 2 and the profiling seat 10 to synchronously heat the framework and the fabric to activate the hot-melt glue, and in the process of downward movement of the upper die mechanism 2, the telescopic assembly 40 is started to drive the fabric to convey inward (i.e. towards the direction of the profiling seat 10) through the cloth hanging needle 410. The purpose of this is to reduce the stretching degree of the fabric (i.e. to reduce the stretching of the fabric perpendicular to the coating direction), thereby avoiding the rebound phenomenon caused by excessive stretching. That is, as the upper die mechanism 2 moves downward, the telescopic assembly 40 controls the action of the cloth hanging needle 410 according to the preset program to gradually adjust the position of the fabric to achieve the best bonding effect, which not only improves the appearance quality of the product, but also enhances the durability of the finished product.

[0039] The cloth hanging assembly 41 further comprises: a lifting cylinder 411 connected to the driving end of the telescopic assembly 40 in the vertical direction, and the output end of the lifting cylinder 411 is connected with an assembly plate 412; a skin clamping cylinder 413 arranged on the assembly plate 412 and arranged in parallel with the lifting cylinder 411, the bottom of the skin clamping cylinder 413 is connected with an L-shaped support block 414, the output end of the skin clamping cylinder 413 is connected with a pressing block 415, and the pressing block 415 is movably pressed on the L-shaped support block 414 to limit the movement of the fabric; an extension plate 416 arranged on the assembly plate 412, and the cloth hanging needle 410 is detachably connected to the end of the extension plate 416 in the vertical direction.

[0040] like Figures 1 to 3 As shown, the design of the extension plate 416 in this embodiment ensures that the positions of the fabric hanging needle 410 and the pressure block 415 do not interfere with each other, guaranteeing the smoothness and stability of the structure during operation; after the fabric hanging needle 410 is connected to the fabric, the fabric can be moved along the fabric by the movement of the telescopic component 40. Figure 1 The fabric is conveyed into the contour seat 10 in the direction of the arrow, ensuring that the fabric is properly stretched or relaxed during the bonding process. Subsequently, the clamping cylinder 413 drives the pressure block 415 to work with the L-shaped support block 414 to clamp and fix the stretched fabric, ensuring stable bonding between the fabric and the frame during the wrapping process. Therefore, through the coordinated work of the lifting cylinder 411, the telescopic component 40, and the fabric hanging needle 410, the position and tension of the fabric can be controlled very precisely, avoiding the problems of excessive stretching or loosening of the fabric that may occur in traditional methods, thus improving production efficiency and product quality consistency.

[0041] An adjustment hole 416a is provided on the extension plate 416, and a locking hole 412a is provided in the assembly plate 412. The adjustment hole 416a and the locking hole 412a can be fixedly connected by fasteners to adjust the relative position between the cloth hanging needle 410 and the contour seat 10.

[0042] Furthermore, such as Figure 2 and Figure 3 As shown, the assembly plate 412 in this embodiment is provided with a locking hole 412a. The adjustment hole 416a and the locking hole 412a can be fixedly connected by fasteners (such as screws or pins, not shown in the figure). The operator can loosen the fasteners as needed to easily and quickly adjust the position of the fabric hanging needle 410, thereby better adapting to the needs of fabrics of different sizes and shapes. This design greatly improves the flexibility and applicability of the equipment, ensuring that the fabric can reach the optimal stretch state during the bonding process (that is, it helps to optimize the tension distribution of the fabric, avoids the problem of excessive stretching or loosening of the fabric that may occur in traditional methods, and significantly improves the appearance quality and durability of the product). After adjustment, tighten the fasteners again to lock the position of the fabric hanging needle 410.

[0043] An installation hole is provided on the extension plate 416. A fixed guide sleeve 416c can be connected to the installation hole through a locking nut 416b. A telescopic cylinder 416d is connected to the bottom of the fixed guide sleeve 416c. The cloth hanging needle 410 is movably disposed in the fixed guide sleeve 416c and connected to the output end of the telescopic cylinder 416d.

[0044] More preferably, such as Figure 3As shown, the embodiment also has mounting holes (not shown in the figure) on the extension plate 416, which are used to connect and fix the guide sleeve 416c, which is firmly installed in the mounting hole of the extension plate 416 through the locking nut 416b. This design allows the operator to conveniently and quickly adjust the position of the cloth hanging needle 410, reduces the debugging time, simplifies the operation process, and improves the work efficiency. At the same time, the telescopic cylinder 416d is directly connected to the cloth hanging needle 410, and the cloth hanging needle 410 moves in the fixed guide sleeve 416c. The fixed guide sleeve 416c can guide and limit the telescopic movement of the cloth hanging needle 410, and can also retract the cloth hanging needle 410 into the fixed guide sleeve 416c when not in use, greatly ensuring that the cloth hanging needle 410 is not easily damaged and prolonging the service life.

[0045] Further preferably, as Figure 3 As shown, the embodiment also has a plurality of occlusal parts 415a arranged at equal intervals on the bottom wall of the pressing block 415. By using the occlusal parts 415a to move and press against the L-shaped support block 414, the friction is increased, the fabric is more stable during processing, the quality problems caused by fabric displacement are reduced, and it is ensured that each step of operation is within the expected range, greatly improving the positioning accuracy of the fabric and helping to improve the quality of the final product.

[0046] The telescopic assembly 40 includes a fixed seat 400 and a moving cylinder 401. The fixed seat 400 is detachably connected to the workbench 1. The moving cylinder 401 is arranged on the fixed seat 400. The moving direction of the output end of the moving cylinder 401 is perpendicular to the profiling seat 10. A moving plate 402 is connected to the output end of the moving cylinder 401. The lifting cylinder 411 is connected to the side wall of the moving plate 402 in the vertical direction.

[0047] Further preferably, as Figure 2 As shown, the fixed seat 400 in the embodiment determines the overall height of the stretching mechanism 4 to ensure that the cloth hanging needle 410 can accurately stretch the fabric. The detachable design of the fixed seat 400 and the way the moving cylinder 401 drives the moving plate 402 can realize high-precision positioning adjustment in the horizontal direction (i.e. the direction indicated by the arrow in the figure), ensuring that the cloth hanging needle 410 can accurately align with the position of the fabric to be processed, improving the processing accuracy. This structure realizes automatic operation adjustment, simplifies the operation process, reduces the need for manual intervention, and greatly improves the work efficiency. Figure 1

[0048] ​The hot-pressing mechanism 3 comprises a mounting frame 30 arranged on the workbench 1, and a moving assembly 31 arranged on the mounting frame 30, wherein the moving assembly 31 comprises a moving frame 310 connected to a driving end of the moving assembly 31, and a plurality of infrared lamp tubes 311 arranged on the moving frame 310 in an array at equal intervals, and the infrared lamp tubes 311 can be synchronously heated when the moving frame 310 moves to between the upper die mechanism 2 and the profiling seat 10.

[0049] As shown in Figure 1 and Figure 4 When the above-mentioned fabric is firmly attached to the profiling seat 10, and the skeleton is vacuum adsorbed on the upper die mechanism 2, the moving assembly 31 is started, so that the moving frame 310 and the plurality of infrared lamp tubes 311 are moved to between the upper die mechanism 2 and the profiling seat 10. In this process, the infrared lamp tubes 311 are synchronously turned on to uniformly heat the fabric placed on the profiling seat 10 and the skeleton on the upper die mechanism 2. It should be noted that since the infrared lamp tubes 311 need to heat the surface of the fabric and the skeleton to 150℃ within 15s, the design of the array and equal interval distribution of the infrared lamp tubes 311 ensures that the heat can be uniformly and efficiently transmitted to the fabric and the skeleton, reduces the problems 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 311 can quickly penetrate the material surface to achieve rapid and uniform heating effect, so that the fabric and the skeleton reach the ideal bonding temperature condition, and after heating is completed, the mold clamping and covering operation can be performed.

[0050] The moving assembly 31 comprises a guide rod 312 and a movable block 313, the guide rod 312 is arranged in parallel with the moving direction of the moving frame 310, the movable block 313 is movably sleeved on the guide rod 312 and connected to the moving frame 310 through a connecting plate 314, and the movable block 313 and the moving frame 310 are both connected with a sliding block 315, and both sides of the mounting frame 30 are provided with a sliding rail 316, and the sliding block 315 is movably connected to the sliding rail 316.

[0051] Further, as shown in Figure 4As shown, the guide rod 312 in the embodiment is connected with a driving motor (not shown in the figure), and the rotation of the guide rod 312 can drive the movable block 313 to reciprocate along the axis direction of the guide rod 312. At the same time, through the structural design of the cooperation of the guide rod 312 and the slide rail 316, it is ensured that the moving frame 310 has high precision and stability during movement, and the problems of uneven heating or position deviation caused by unstable movement or mechanical vibration are avoided, and the processing quality is improved. The moving assembly 31 adopts a modular design, which is easy to disassemble and replace, which not only facilitates 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 312 and the movable block 313 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 Figure 4 shown, the moving frame 310 is also provided with a plurality of light shielding plates 32. Since the infrared lamp tube 311 generates extremely high brightness due to instantaneous heating, long-term operation of the equipment by employees can cause eye damage. By adding metal light shielding plates 32 (such as stainless steel, aluminum alloy, etc.) at the periphery (which can be the front section, left / right section) of the infrared lamp tube 311, the heat loss is prevented, the heating efficiency is improved, and the light is effectively blocked, providing a safer working environment for workers.

[0053] Further, as Figure 5 shown, the upper die mechanism 2 includes a clamping cylinder 20 and a movable die block 21. The clamping cylinder 20 is arranged in the vertical direction, and the movable die block 21 is connected to the output end of the clamping cylinder 20. As the clamping cylinder 20 moves downward along the vertical direction, the movement trajectory of the movable die block 21 is ensured to be accurate, thereby realizing accurate butt joint between the framework and the fabric and avoiding quality problems caused by position deviation. Preferably, the same slide block 315 and slide rail 316 structure as the above structure can be arranged on one side of the movable die block 21 to further improve the accuracy of the reciprocating movement of the framework. It should be noted that the structure and working principle of the upper die mechanism 2 in the embodiment are the same as those in the existing technology of the heat pressing and coating forming process, which will not be described here.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
