Description

Technical Field

[0001] This application relates to the technical field of shoe molding equipment, and more specifically, it relates to a KPU textured molding equipment and its molding method. Background Technology

[0002] In footwear products, especially athletic and casual shoes, textured rubber patterns with three-dimensional structures and decorative effects are often incorporated into the upper or specific areas to enhance local strength, improve appearance, or achieve specific functions, such as guiding anti-slip or breathable zones. These patterns are typically made of materials such as thermoplastic polyurethane (KPU), and their molding process is crucial to the quality, aesthetics, and production efficiency of the final product.

[0003] Currently, the mainstream method for molding rubber surface patterns in the industry is the mold transfer method. Specifically, this process first requires the creation of a dedicated molding mold based on the designed pattern. The mold surface is machined with a network of recessed adhesive grooves opposite to the target pattern. The process flow includes: operators manually applying liquid or paste-like adhesive to the various adhesive grooves in the mold; subsequently, the mold with the adhesive applied is placed in an oven or drying tunnel for heating, allowing the adhesive to cure; after curing, the molded rubber surface pattern is peeled off from the mold and finally transferred to a predetermined position on the shoe upper through hot pressing or bonding.

[0004] Regarding the aforementioned technologies, relying entirely on manual dispensing and scraping of adhesive is slow and requires a high level of worker skill, making it difficult to meet the demands of large-scale, fast-paced modern production, while labor costs are constantly rising. Manual operation inevitably suffers from uneven adhesive volume control, incomplete filling, or adhesive overflow. Inconsistent adhesive filling in the glue tank can easily lead to defects such as insufficient adhesive, uneven thickness, and unclear edges in the final pattern, affecting the product's appearance and performance. Precise control of adhesive volume is difficult in manual operation; often, excessive adhesive is applied to avoid insufficient coverage, and the scraped-off excess adhesive is often discarded, resulting in material waste and increased production costs. When filling small, complex glue tanks of varying depths, adhesive easily traps air, forming bubbles. These bubbles, after curing, form pores and depressions inside or on the surface of the pattern, significantly reducing the product's strength, durability, and aesthetics. Manual operation is unlikely to effectively remove these tiny bubbles.

[0005] Therefore, the industry urgently needs to develop an automated and intelligent KPU shoe upper adhesive molding equipment to overcome the limitations of manual operation, achieve high precision, high uniformity, and high efficiency in adhesive filling, and effectively solve the problem of air bubbles, thereby improving the molding quality and production efficiency of adhesive patterns on footwear products. Summary of the Invention

[0006] In order to solve the problems of low efficiency, uneven glue volume control, glue waste, and difficulty in removing air bubbles caused by manual glue application in the related technology, this application provides a KPU glue texture forming equipment and its forming method.

[0007] In the first aspect, this application provides a KPU textured molding device, which adopts the following technical solution:

[0008] A KPU textured molding device, comprising:

[0009] Organism;

[0010] A conveyor line is provided on the machine body, the conveyor line being used to convey a mold with a recessed rubber groove;

[0011] The mold inspection mechanism, mold release agent spraying mechanism, glue dispensing mechanism, first vacuuming mechanism, first glue scraping mechanism, second vacuuming mechanism, and second glue scraping mechanism are sequentially arranged along the conveying direction of the conveyor line.

[0012] And control systems used to coordinate the operation of various mechanisms.

[0013] The conveyor line is L-shaped and includes a first roller conveyor section, a second roller conveyor section, and a third roller conveyor section that are connected in sequence with the same conveying direction, as well as a fourth roller conveyor section and a fifth roller conveyor section that are connected in sequence with the same conveying direction, and the conveying direction of the fourth roller conveyor section is perpendicular to the conveying direction of the third roller conveyor section.

[0014] The first vacuuming mechanism is located between the third roller conveyor section and the fourth roller conveyor section, and is used to receive the mold filled with glue from the third roller conveyor section and perform vacuuming.

[0015] The second vacuuming mechanism is located between the fourth roller conveyor section and the fifth roller conveyor section, and is used to receive the mold filled with glue from the fourth roller conveyor section and perform vacuuming.

[0016] By adopting the above technical solutions, an automated production line was set up, including mold inspection, release agent spraying, glue spraying, two vacuuming processes, and two glue scraping processes. An L-shaped conveyor line connects each workstation in an orderly manner, realizing automated production from mold recognition to glue surface pre-forming. The L-shaped conveyor line layout optimizes space utilization, replaces traditional manual glue dispensing and scraping operations with equipment, significantly improves production efficiency and consistency, and achieves vacuuming to remove air bubbles, providing a hardware foundation for the large-scale manufacturing of high-quality glue textures.

[0017] Preferably, the mold detection mechanism is located above the first roller conveyor section and includes a CCD camera. The CCD camera is used to capture identification marks on the mold. The control system has a pre-stored mold model database and can identify the mold model based on the captured images and communicate with the subsequent processes to implement the corresponding processing programs for each process.

[0018] By adopting the above technical solution, a mold inspection mechanism based on a CCD camera was set up, and in conjunction with the mold model database pre-stored in the control system, automatic mold identification and intelligent calling of processing programs were realized. This allows the equipment to flexibly adapt to molds with different patterns without manual intervention to switch parameters, significantly improving the equipment's multi-model compatibility and the level of production intelligence, reducing preparation time and human error, and providing an accurate information starting point for precise operations at subsequent workstations.

[0019] Preferably, the mold release agent spraying mechanism is located above the second roller conveyor section, and includes a mold release agent spray gun, a purging nozzle disposed on the mold release agent spray gun, and a first dual-axis moving drive frame for driving the mold release agent spray gun to move in the horizontal plane.

[0020] By adopting the above technical solution, a release agent spray gun driven by a first dual-axis moving drive frame is installed above the second roller conveyor section, realizing the automation and area controllability of release agent spraying. Compared with manual application, this mechanism can ensure that the release agent is evenly and thinly covered in the glue tank, which not only guarantees the subsequent demolding effect, but also avoids waste or local accumulation, laying a good foundation for the smooth filling of glue and final demolding.

[0021] Preferably, the glue dispensing mechanism is disposed above the third roller conveying section and includes a glue dispensing valve, a glue supply component for supplying glue to the glue dispensing valve, a second dual-axis moving drive frame for driving the glue dispensing valve to move in the horizontal plane, and a first lifting drive component for driving the glue dispensing valve to rise and fall in the vertical direction.

[0022] By adopting the above technical solution, the glue dispensing mechanism located above the third roller conveyor section consists of a glue dispensing valve controlled by a second dual-axis moving drive frame for horizontal movement and a glue supply component controlled by a first lifting drive assembly for vertical lifting. This enables the glue spraying process to perform precise path planning and glue quantity control in three-dimensional space based on the identified mold model, thereby achieving automated and uniform filling of the glue into complex glue tanks. This overcomes the problems of slow speed, uneven glue quantity, and incomplete filling caused by manual glue dispensing, and effectively reduces glue waste.

[0023] Preferably, the first vacuuming mechanism and the second vacuuming mechanism have the same structure, both including: a base plate, a mounting frame, a second lifting drive assembly, a closed cover driven by the second lifting drive assembly to lift and lower, and a vacuum pump; the base plate is positioned lower than the roller conveying surface of the conveyor line, and the closed cover, after being lowered, can seal and cooperate with the base plate to form a vacuum chamber for accommodating the mold, and the vacuum pump is connected to the vacuum chamber for evacuating and de-vacuuming the vacuum chamber.

[0024] By adopting the above technical solution, two vacuuming processes are set up between the glue spraying and the two glue scraping processes. The first vacuuming allows the glue to initially penetrate under negative pressure and removes most of the gas; the second vacuuming further removes air bubbles remaining in the dead corners of the glue tank and inside the glue after the first glue scraping. Staged degassing improves the density of the glue and the surface quality after molding.

[0025] Preferably, both the first vacuuming mechanism and the second vacuuming mechanism are further provided with a push-out component, which includes a linear module, a connecting frame driven by the linear module, a lifting cylinder disposed on the connecting frame, and a push plate connected to the lower end of the lifting cylinder.

[0026] By adopting the above technical solutions, the developed components enable the automatic transfer of molds between the vacuum station and the conveyor line, ensuring the automated and continuous operation of the entire process.

[0027] Preferably, the first scraping mechanism is disposed in the fourth roller conveyor section, and the second scraping mechanism is disposed in the fifth roller conveyor section. The first and second scraping mechanisms have similar structures, each including a scraping component and a third dual-axis moving drive frame for driving the scraping component to move in the horizontal plane, and a third lifting drive component for driving the scraping component to rise and fall in the vertical direction. The scraping component includes a scraping frame and a flexible scraper installed at the lower part of the scraping frame. The fourth and fifth roller conveyor sections are each provided with clamping components for clamping and fixing the mold at the corresponding scraping station.

[0028] By adopting the above technical solution, a scraping assembly driven by a third dual-axis moving drive frame performs scraping. The scraping assembly uses a flexible scraper. The first scraping is performed after preliminary vacuuming, mainly to scrape off excess glue over large areas and promote the flow and filling of the glue tank. The second scraping is performed after deep vacuuming, for fine smoothing and thorough removal of residual glue from the surface. The flexible scraper can effectively scrape glue without damaging the mold or the formed glue pattern. The combination of two scraping operations and two vacuuming operations ensures the fullness of the glue tank filling, the flatness of the glue surface, and the clarity of the pattern edges, ultimately obtaining a glue pattern with uniform thickness and exquisite appearance.

[0029] Secondly, this application provides a KPU textured molding method, which adopts the following technical solution:

[0030] A method for molding KPU textured surfaces includes the following steps:

[0031] Step S1: The mold is conveyed via a conveyor line, and its model is first identified by the mold inspection mechanism;

[0032] Step S2: After identification, the mold enters the mold release agent spraying station, where the mold release agent spraying mechanism sprays mold release agent into the mold's glue tank and removes excess mold release agent.

[0033] Step S3: The mold enters the glue dispensing station, and the glue dispensing mechanism accurately pours glue into the glue tank according to the mold model;

[0034] Step S4: After the glue is poured, the mold is transferred to the first vacuuming mechanism for the first vacuuming process, so that the glue initially fills the glue tank and removes some of the gas.

[0035] Step S5: After the first vacuuming, the mold is transported to the first glue scraping station, where the first glue scraping mechanism scrapes the glue on the surface of the mold to spread the glue evenly and make the glue fill the glue groove of the mold evenly.

[0036] Step S6: After the first scraping of the glue, the mold is transferred to the second vacuuming mechanism for a second vacuuming process to thoroughly remove air bubbles inside the glue and in the dead corners of the glue tank, and to further fill the glue tank of the mold with glue.

[0037] Step S7: After the second vacuuming, the mold is transported to the second scraping station, where the second scraping mechanism performs fine scraping to remove residual adhesive from the mold surface.

[0038] Step S8: The mold with the finished fine scraping is sent out by the conveyor line, waiting for subsequent curing and demolding.

[0039] By adopting the above technical solution, the method of this application, starting from mold identification, goes through spraying release agent, spraying adhesive, two vacuum degassing processes, and two adhesive scraping finishing processes, forming a logically rigorous and step-by-step processing flow. It transforms the hardware advantages of the equipment into stable, reliable, and repeatable process results, systematically ensuring high efficiency and high quality in the final textured molding, and providing a standardized and scalable solution for the automated production of shoe upper textures.

[0040] In summary, this application includes at least one of the following beneficial technical effects:

[0041] 1. An automated production line was set up, including mold inspection, release agent spraying, glue spraying, two vacuuming processes, and two glue scraping processes. An L-shaped conveyor line connects each workstation in an orderly manner, realizing automated production from mold recognition to glue surface pre-forming. The L-shaped conveyor line layout optimizes space utilization, and the equipment replaces traditional manual glue dispensing and scraping operations, greatly improving production efficiency and consistency. In addition, vacuuming and air bubble removal are achieved, providing a hardware foundation for the large-scale manufacturing of high-quality glue textures.

[0042] 2. The method described in this application starts with mold identification and proceeds through processes such as spraying release agent, spraying adhesive, two vacuum venting operations, and two adhesive scraping and finishing operations, forming a logically rigorous and progressive processing flow. It transforms the hardware advantages of the equipment into stable, reliable, and repeatable process results, systematically ensuring high efficiency and high quality in the final textured molding, and providing a standardized and scalable solution for the automated production of shoe upper textures.

[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0051] Reference Figure 1 and Figure 3A KPU textured molding device includes a mold 1, a conveyor line 2 for carrying and conveying the mold 1, and a control system 3. The conveyor line 2 includes an L-shaped body 21, on which a first roller conveyor section 22, a second roller conveyor section 23, a third roller conveyor section 24, a fourth roller conveyor section 25, and a fifth roller conveyor section 26 are sequentially arranged. The first to third roller conveyor sections 24 have the same conveying direction, forming one arm of the L-shape; the fourth and fifth roller conveyor sections 26 have the same conveying direction and are perpendicular to the direction of the first three sections, forming the other arm of the L-shape. Each roller conveyor section is driven by a motor mounted on the frame of the machine body 21 to rotate a set of parallel rollers. Adjacent rollers are connected by belt drive, so as to smoothly convey the mold 1 placed on it. The mold 1 is processed with a network of recessed grooves opposite to the target rubber texture. Furthermore, the conveying ends of the first roller conveyor section 22, the second roller conveyor section 23, the third roller conveyor section 24, the fourth roller conveyor section 25 and the fifth roller conveyor section 26 are all provided with a baffle assembly 27 to block the conveying of the mold 1 or to release the blockage. Each baffle assembly 27 includes a first lifting drive component 271 and a baffle 272 driven by the lifting drive component. The first lifting drive component 271 is preferably a cylinder.

[0052] Reference Figure 1 The processing and conveying of mold 1 begins at the first roller conveyor section 22. A mold 1 detection mechanism is installed on the machine body 21 along the first roller conveyor section 22. This mechanism includes a support 41 erected on one side of the machine body 21, with a CCD camera 42 mounted on top of the support 41, its lens pointing vertically downwards towards the conveyor surface. Mold 1 is pre-marked with identification tags such as QR codes or specific shaped markings. When mold 1 moves with the rollers to a position below the camera, the camera takes a picture of it. The control system 3 internally stores a standard image database of various mold 1 models and integrates an image analysis module. The camera transmits the captured image of mold 1 to the control system 3, and the image analysis module compares and analyzes it with the images in the database, thereby automatically identifying the mold 1 model and calling the matching subsequent processing control program, achieving flexible production.

[0053] Reference Figure 1 and Figure 2After identification, mold 1 is conveyed to the second roller conveyor section 23. A mold release agent spraying mechanism 5 is installed on the machine body 21 at the second roller conveyor section 23. The mold release agent spraying mechanism 5 includes a mold release agent spray gun 51, a purging nozzle 511 mounted on the mold release agent spray gun 51, and a first dual-axis moving drive frame 52. The first dual-axis moving drive frame 52 is a gantry or slide system driven by a servo motor and capable of precise movement along the X and Y axes in a horizontal plane. The mold release agent spray gun 51 is mounted on this drive frame and controlled by the control system 3. The first dual-axis moving drive frame 52 drives the spray gun to move above mold 1 along a preset path. Simultaneously, the spray gun evenly sprays atomized mold release agent into each groove of mold 1, preparing for subsequent demolding. Excess mold release agent is removed by the purging nozzle 511.

[0054] Reference Figure 1 and Figure 4 Next, mold 1 enters the third roller conveyor section 24, where the machine body 21 is equipped with a dispensing mechanism 6. The dispensing mechanism 6 includes a dispensing valve 61, a dispensing assembly 62 for supplying adhesive, a second dual-axis moving drive frame 63, and a first lifting drive assembly 64. The first lifting drive assembly 64 is directly connected to the dispensing valve 61 and can drive the dispensing valve 61 to move up and down along the vertical Z-axis. This first lifting drive assembly 64 is selected as a lead screw module. The first lifting drive assembly 64 is mounted on the second dual-axis moving drive frame 63, which is also a precision XY-axis moving platform with a structure similar to the first dual-axis moving drive frame 52. The dispensing assembly 62 includes a glue tank 621 located outside the conveyor line 2, a pump 622 (not shown in the figure) mounted on the glue tank 621, and a connecting hose 623 (not shown in the figure). The pump 622 delivers the liquid KPU adhesive from the glue tank 621 to the dispensing valve 61 through the hose 623. During operation, the control system 3 controls the second dual-axis moving drive frame 63 to drive the dispensing valve 61 to scan and move above the mold 1 according to the program of the mold 1 model. At the same time, the first lifting drive component 64 lowers the height of the dispensing valve 61 in a timely manner to approach the glue tank. The pump 622 draws the glue in the glue bucket 621 to the dispensing valve 61, and the dispensing valve 61 accurately sprays the glue into the glue tank.

[0055] Reference Figure 1 and Figure 4A blocking assembly 28 is provided on one side of the third roller conveyor section 24, and a pushing assembly 29 is provided on the side away from the blocking assembly 28. The blocking assembly 28 includes a second lifting drive 281 and an abutment plate 282 driven by the second lifting drive 281. The second lifting drive 281 is preferably a cylinder. When the mold 1 is conveyed to the third roller conveyor section 24, the abutment plate 282 rises, and the pushing assembly 29 pushes the mold 1 to abut against the abutment plate 282. The pushing assembly 29 includes a rodless cylinder 291, which is located at the bottom of the roller and extends along the axial direction of the roller. Its mover is equipped with a force plate 292, which pushes the mold 1. Furthermore, when it is necessary to transfer the mold 1, the rodless cylinder 291 also drives the force plate 292 to push the mold 1 laterally away from the third roller conveyor section 24.

[0056] Reference Figure 1 and Figure 5 A first vacuum mechanism 7 is provided between the third roller conveyor section 24 and the fourth roller conveyor section 25 on the machine body 21. The pushing component 29 pushes the mold 1 into the first vacuum mechanism 7. The first vacuum mechanism 7 includes a base plate 71 fixedly mounted on the machine body 21, a mounting frame 72 spanning above the base plate 71, a second lifting drive component 73 located on top of the mounting frame 72, a closed cover 74 connected to the second lifting drive component 73, and a vacuum pump 75. The closed cover 74 is driven to rise and fall by the Z-axis lifting and lowering of the mounting frame 72 by the second lifting drive component 73. The base plate 71 is flat and its position is slightly lower than the roller conveyor surfaces at both ends. Initially, the closed cover 74 is raised. After the mold 1 is pushed to the center of the base plate 71 by the pushing component 29, the second lifting drive component 73 drives the closed cover 74 to fall, so that its lower end fits tightly against the base plate 71, forming a sealed cavity that covers the mold 1. The second lifting drive component 73 is preferably a cylinder. A vacuum pump 75 is located at the bottom of the base plate 71 and connects to the cavity through an opening in the base plate 71. When the vacuum pump 75 is activated, it evacuates the cavity. Since the glue tank is filled with glue but has not yet been leveled, there may be gaps and air bubbles inside. At this time, the external air pressure drops suddenly, and the air inside the glue tank expands and escapes. At the same time, the glue is "drawn in" more deeply under the action of the air pressure difference and fills the tiny corners of the glue tank, achieving preliminary guided filling and coarse venting. An observation window 741 is provided on the sealed cover 74 to facilitate observation of the vacuum status of the glue inside the cavity.

[0057] Reference Figure 1 and Figure 5An ejection assembly 76 is provided on the base plate 71. After the first vacuuming process is completed, the sealing cover 74 is raised. The ejection assembly 76 pushes the mold 1 into the third roller conveyor section 24. The ejection assembly 76 includes a linear module 761 arranged along the ejection direction of the mold 1, a connecting frame 762 mounted on the mover of the linear module 761, a lifting cylinder 763 mounted on the connecting frame 762, and a push plate 764 connected to the drive shaft of the lifting cylinder 763. The drive shaft of the lifting cylinder 763 is arranged downward. During ejection, the lifting cylinder 763 drives the push plate 764 to descend, making the push plate 764 lower than the top surface of the mold 1. The linear module 761 drives the connecting frame 762 to move, causing the push plate 764 to move and smoothly push the mold 1 to the starting end of the fourth roller conveyor section 25.

[0058] Reference Figure 1 and Figure 6 The machine body 21 is equipped with a first scraping mechanism 8 for scraping glue and a clamping assembly 81 for clamping the mold 1 on the fourth roller conveyor section 25. After the mold 1 enters the fourth roller conveyor section 25, the clamping assembly 81 is activated to clamp and fix the mold 1, preventing it from moving during the subsequent glue scraping process. The clamping assembly 81 is selected as a pneumatic gripper or clamping cylinder symmetrically arranged on both sides of the conveyor section, and its clamping arms can move towards each other to reliably clamp the mold 1 from both sides. After the mold 1 is clamped, the first scraping mechanism 8 starts to work. The first scraping mechanism 8 includes a scraping assembly 82, a third dual-axis moving drive frame 83, and a third lifting drive assembly 84. The scraping assembly 82 includes a scraping frame 821 and a flexible scraper 822 installed below it. The entire scraping assembly 82 is mounted on the third lifting drive assembly 84, which drives the lifting mechanism. The third lifting drive assembly 84 is preferably a lead screw module and is mounted on the third dual-axis moving drive frame 83. The third dual-axis moving drive frame 83 is structurally similar to the first dual-axis moving drive frame 52, both being gantry frames or slide systems capable of precise movement along the X and Y axes in a horizontal plane. The control system 3 controls the drive frame to move the scraper along the X and Y axes above the surface of the mold 1. The lower edge of the scraper contacts the surface of the mold 1 with a certain pressure and angle. The main purpose of this scraping is to scrape and smooth the glue accumulated on the surface of the mold 1 and at the glue groove opening after spraying, forcing the glue to fill all the glue grooves more fully and evenly, and removing some large air bubbles from the surface. A recycling trough 211 is provided on one side of the fourth roller conveyor section 25 of the machine body 21. Excess glue falls into the recycling trough 211 along the edge of the mold 1 for easy collection and processing.

[0059] Reference Figure 1 and Figure 5A second vacuuming mechanism 9 is installed between the fourth roller conveyor section 25 and the fifth roller conveyor section 26 on the machine body 21. After the first scraping is completed, the clamping component 81 is released, the material blocking component 27 is released, and the mold 1 is conveyed to the second vacuuming mechanism 9. The structure of the second vacuuming mechanism 9 is exactly the same as that of the first vacuuming mechanism 7. At this station, the mold 1 is sent under the closed cover 74 again for vacuuming. At this time, the glue tank is basically filled with glue and leveled. The main purpose of this vacuuming is to remove the tiny air bubbles trapped inside the glue and in the dead corners of the glue tank, and to further fill the glue tank of the mold with glue. In a vacuum environment, these air bubbles expand in volume and migrate to the glue surface and burst, thereby greatly reducing the air bubble defects in the finished glue texture and significantly improving the density and strength of the product.

[0060] Reference Figure 1 and Figure 6 After deep venting is completed, mold 1 is pushed to the fifth roller conveyor section 26. This section is also equipped with a baffle assembly 27 and a clamping assembly 81, and a second scraping mechanism 10, whose function is the same as that of the fourth roller conveyor section 25: first, to position and clamp mold 1. Then, the second scraping mechanism 10 is activated. The structure of the second scraping mechanism 10 is the same as that of the first scraping mechanism 8. This scraping is a fine scraping, the purpose of which is to thoroughly remove the extremely thin layer of glue or glue film that may still remain on the surface of mold 1 after two vacuuming and one scraping, ensuring that the surface of mold 1 is smooth, the glue lines are clear and sharp, and there is no excess glue. The machine body 21 is provided with a recovery tank 211 on both the first scraping mechanism 8 and the second scraping mechanism 10. The small amount of residual glue scraped off is also guided into the recovery tank 211 next to the station.

[0061] Reference Figure 1 and Figure 6 Finally, the clamping component 81 is released, the blocking component 27 releases, and a KPU textured material with full, uniform, and bubble-free internal glue filling and clean surface treatment is cured and formed in the mold 1. It is then sent out by the fifth roller conveyor section 26, waiting for subsequent curing, demolding and transfer processes.

[0062] Throughout the process, the drive of conveyor line 2, the coordinated action of various mechanisms, the control of vacuum, and the paths and parameters of glue spraying and scraping are all uniformly scheduled and monitored by the central control system 3. This achieves fully automated, high-precision, and high-quality KPU textured molding production, overcoming many drawbacks of manual operation such as slow speed, uneven quality, numerous air bubbles, and material waste. In this embodiment, the control system 3 is connected to the MES system for easy management of relevant information during production and subsequent traceability.

8. A method for KPU textured molding using the equipment described in any one of claims 1-7, characterized in that, Includes the following steps: Step S1: The mold is conveyed via a conveyor line, and its model is first identified by the mold inspection mechanism; Step S2: After identification, the mold enters the mold release agent spraying station, where the mold release agent spraying mechanism sprays mold release agent into the mold's glue tank and removes excess mold release agent. Step S3: The mold enters the glue dispensing station, and the glue dispensing mechanism accurately pours glue into the glue tank according to the mold model; Step S4: After the glue is poured, the mold is transferred to the first vacuuming mechanism for the first vacuuming process, so that the glue initially fills the glue tank and removes some of the gas. Step S5: After the first vacuuming, the mold is transported to the first glue scraping station, where the first glue scraping mechanism scrapes the glue on the surface of the mold to spread the glue evenly and make the glue fill the glue groove of the mold evenly. Step S6: After the first scraping of the glue, the mold is transferred to the second vacuuming mechanism for a second vacuuming process to thoroughly remove air bubbles inside the glue and in the dead corners of the glue tank, and to further fill the glue tank of the mold with glue. Step S7: After the second vacuuming, the mold is transported to the second scraping station, where the second scraping mechanism performs fine scraping to remove residual adhesive from the mold surface. Step S8: The mold with the finished fine scraping is sent out by the conveyor line, waiting for subsequent curing and demolding.
