Description

Technical Field

[0001] This invention relates to the field of foaming production line technology, and in particular to a fully automated annular reflux production equipment for polyurethane product casting. Background Technology

[0002] In existing foaming production lines, foaming is typically carried out using single molds, resulting in low capacity. While some production lines can transport multiple molds, automation of mold closing and locking requires power and air supply. In some production lines, the energy supply is not continuous and requires manual connection, with each section using a quick-connect plug to insert into the energy pipeline interface on the mold frame, which is inconvenient. Furthermore, in some production lines, the wiring layout is not rational, resulting in complex and messy pipelines that are easily damaged or tangled during movement, leading to frequent malfunctions. Once a malfunction occurs, the entire line needs to be shut down, making troubleshooting difficult, repair time long, and potentially causing multiple products to be scrapped, resulting in high scrap rates and significant losses. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fully automatic annular reflow production equipment for polyurethane product casting that allows multiple foaming molds to perform foaming operations simultaneously and has simple wiring connections.

[0004] The objective of this invention is achieved through the following technical solution:

[0005] A fully automated circular reflow production equipment for polyurethane product casting includes: a traveling auxiliary device, a conveying device, and a mold-carrying device. The traveling auxiliary device includes a conveying area and a wiring mechanism. The wiring mechanism includes a cable holder, a slip ring assembly, a cable carrier, and a moving frame. The cable holder is disposed within the conveying area. The slip ring assembly and the cable carrier are disposed on the cable holder and are slidably connected. The slip ring assembly is connected to the cable carrier, and the lead wire of the slip ring assembly is fixedly fixed on the moving frame. The movement of the moving frame drives the slip ring assembly and the cable carrier to move forward or backward on the cable holder. The conveying device is disposed within the conveying area and performs a circular motion within the conveying area. The moving frame is fixedly connected to the conveying device. The mold-carrying device is disposed on the conveying device and is used to load foaming molds. The mold-carrying device is connected to the cable fixed on the moving frame.

[0006] In one embodiment, the traveling assist device further includes an annular pad and an annular guide rail. The annular pad surrounds the outside of the conveying area, the annular guide rail is laid on the annular pad, and the conveying device is slidably connected to the annular guide rail.

[0007] In one embodiment, the annular pad is formed by two arcuate portions at both ends and two straight portions on both sides, with the two ends of the straight portions respectively connected to the arcuate portions.

[0008] In one embodiment, the straight section is composed of multiple straight pads connected in sequence.

[0009] In one implementation scheme, there are two annular guide rails: one annular guide rail is laid along the travel path of the conveying device, and the other annular guide rail is laid along the travel path of the mold carrier device.

[0010] In one embodiment, the cable tray includes a frame, a cable chain bracket, and a cable chain groove. The cable chain brackets are spaced apart on the frame, the cable chain grooves are mounted on the cable chain brackets, and a slide rail is provided on the cable chain groove. The cable chain is disposed in the cable chain groove, and the slip ring assembly is slidably connected to the slide rail. When sliding, it drives the cable chain to move within the cable chain groove.

[0011] In one embodiment, the slip ring assembly includes a base and a slip ring. The base is symmetrically provided with pulley groups on opposite sides, the pulley groups slide on the slide rail, and the slip ring is connected to the base.

[0012] In one embodiment, positioning wheels are symmetrically arranged on opposite sides of the base, and positioning wheel pressure plates are symmetrically arranged above and below the positioning wheels on the inner side of the base.

[0013] In one embodiment, the slip ring includes a fixed part and a rotating part. The fixed part is connected to the base via a flange, and the rotating part is rotatably connected to the fixed part. A drive ring handle is provided between the rotating part and the fixed part to ensure the concentricity of the relative rotation of the rotating part and the fixed part.

[0014] In one embodiment, multiple mold carriers and multiple mobile frames are provided, and the mold carriers and multiple mobile frames are spaced apart on the conveying device.

[0015] Compared with the prior art, the present invention has at least the following advantages:

[0016] 1. The fully automated circular reflow production equipment for polyurethane product casting of the present invention integrates the cable tray of the wiring mechanism into the conveyor area, eliminating the need for additional space. A slip ring assembly linked to a cable carrier is installed on the cable tray. The cable outlet of the slip ring assembly is fixed to a movable frame, which is fixed to the conveyor device and moves in a circular motion with the conveyor device. This ensures the consistency of the relative positions of the movable frame and the mold carrier, avoiding the problems of fixed wiring or the use of a separate cable carrier, which are complex and prone to cable twisting and breakage, and cumbersome power connection to the mold carrier. The entire production line of the present invention is compact, operates stably, and is highly efficient. Furthermore, the modular design of the slip ring assembly and cable carrier allows for quick disassembly and replacement.

Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0027] It should be understood that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., 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 application according to the specific circumstances.

[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0029] Please see Figure 1 , Figure 2 An embodiment of a fully automated annular reflow production equipment for polyurethane product casting includes: a traveling auxiliary device 500, a conveying device 600, and a mold carrier device 700. The traveling auxiliary device 500 includes a conveying area 510 and a wiring mechanism 520. The wiring mechanism 520 includes a cable holder 521, a slip ring assembly 522, a cable carrier 523, and a moving frame 524. The cable holder 521 is disposed within the conveying area 510. The slip ring assembly 522 and the cable carrier 523 are disposed on the cable holder 521. The slip ring assembly 522 is slidably connected to the cable holder 521. Connected to the cable carrier 523, the cable extension of the slip ring assembly 522 is fixed on the movable frame 524. The movement of the movable frame 524 drives the slip ring assembly 522 and the cable carrier 523 to move forward or backward on the cable tray 521. The conveying device 600 is set in the conveying area 510. The conveying device 600 is slidably connected to the annular guide rail 520. The movable frame 524 is fixedly connected to the conveying device 600. The mold carrier 700 is connected to the conveying device 600 and is used to load the foaming mold. The mold carrier 700 is connected to the cable fixed on the movable frame 524.

[0030] It should be noted that the hub frame 521, as a load-bearing structure, is fixed within the conveying area 510. The slip ring assembly 522 is slidably connected to the hub frame 521 and can move flexibly along the hub frame 521. During the circular conveying process, air, electricity, water, and other cables are integrated within the drag chain 523, which is securely mounted on the hub frame 521. Its outlet end is connected to the inlet end of the slip ring assembly 522. When the slip ring assembly 522 slides on the hub frame 521, it drives the drag chain 523 to move synchronously, thus solving the problem of transmission and layout of air, electricity, water, and other cables during the circular conveying process. This ensures stable connection of the lines and avoids damage caused by bending or tangling of the lines. The conveying device 600 provides reliable power support for the circular conveying of the mold carrier device 700. The moving frame 524 is fixedly connected to the conveying device 600. When the conveying device 600 is started and... When the circular conveying begins, the moving frame 524 moves synchronously, enabling it to precisely follow the trajectory of the conveying device 600. This ensures that the movement of the slip ring assembly 522 and the drag chain 523 is highly consistent with the operation of the conveying device 600. The mold carrier 700 is connected to the conveying device 600, and the foaming mold is loaded onto the mold carrier 700. As the conveying device 600 moves in a circular motion, the mold carrier 700 also moves in a circular motion. During this circular motion, it completes a series of processes in foaming production, including mold loading, mold closing, mold locking, glue injection, unlocking, and mold unloading. At the same time, the mold carrier 700 is connected to the fixed cable on the moving frame 524. This ensures that the mold carrier 700 can continuously obtain the necessary energy supply such as gas, electricity, and water during the foaming production process, guaranteeing normal foaming production during the conveying process. In practical operation, when the conveyor 600 is started, it drives the moving frame 524 and the mold carrier 700 to move together along the circular guide rail. The slip ring assembly 522 and the cable carrier 523 slide smoothly on the hub frame 521. The cable extending from the outlet end of the slip ring assembly 522 is fixed on the moving frame 524. As the moving frame 524 moves with the transmission device 600, it drives the slip ring assembly 522 and the cable carrier 523 to move forward or backward on the hub frame 521. In this way, the mold carrier 700 obtains power through the wiring on the moving frame 524 during the conveying process, ensuring the normal operation of the foaming mold. This working mode enables the entire production line to operate efficiently and stably, realizing automatic circular conveying of the foaming mold, improving production efficiency, reducing labor costs, and ensuring the stability of product quality.

[0031] The aforementioned production line integrates the cable tray 521 of the wiring mechanism 520 within the conveyor area 510, eliminating the need for additional space. The cable tray 521 is equipped with a slip ring assembly 522 that links with the cable carrier 523. The cable extension of the slip ring assembly 522 is fixed to a movable frame 524, which is fixed to the conveyor device 600 and moves in a circular motion with it. This ensures the relative position of the movable frame and the mold carrier 600 is consistent, avoiding the problems of fixed wiring or separate cable carrier movement, which are complex and prone to cable twisting and breakage, as well as difficulties in power connection to the mold carrier 600. The entire production line is compact, operates stably, and is highly efficient. Furthermore, the modular design of the slip ring assembly and cable carrier allows for quick disassembly and replacement.

[0032] Furthermore, the travel assist device 500 also includes an annular pad 530 and an annular guide rail (not shown in the figure). The annular pad 530 surrounds the outside of the conveying area 510, and the annular guide rail is laid on the annular pad 530. The conveying device 600 is slidably connected to the annular guide rail.

[0033] It should be noted that the annular pad 530 can be laid on the ground outside the conveying area 510 with anchor bolts to provide uniform support for the conveying device 600 to drive the moving frame 524 and the mold carrier device 700 to run in a ring, reducing the deviation or shaking of the conveying device 600 caused by uneven ground. Furthermore, an annular guide rail is set to ensure that the conveying device 600 is conveyed smoothly along the annular guide rail. Depending on the specific working conditions and environment, the annular pad 530 can also be made of wear-resistant, moisture-proof, sound-absorbing, and shock-absorbing materials.

[0034] To facilitate the fabrication, installation, and maintenance of the annular pad 530, the annular pad 530 is formed by two arc-shaped portions 531 at both ends and two straight portions 532 on both sides. The two ends of the straight portions 531 are connected to the arc-shaped portions 531 respectively. In other words, the annular pad 530 is assembled in modules. In this way, when a part is damaged, the damaged part can be quickly replaced without replacing the whole part, saving time and costs and reducing maintenance costs. Moreover, different materials or thicknesses can be used for different parts, thereby optimizing the local strength of the annular pad 530.

[0035] To facilitate further matching of production capacity requirements, the straight section 531 is divided into multiple straight pads connected in sequence. In this way, by increasing the number of straight pads, the length of the annular pad 530 can be increased, and the area of ​​the conveying area 510 can be increased to accommodate a longer conveying device 600, increase the number of mold carrier devices 700, and expand production capacity.

[0036] Two circular guide rails are provided. One circular guide rail is laid along the travel path of the conveyor device 600, and the other circular guide rail is laid along the travel path of the mold carrier device 700.

[0037] Understandably, the annular guide rail laid along the travel path of the conveyor 600 is responsible for overall motion control and bears the weight of the conveyor 600, the mold carrier 700 and the mold it carries. The annular guide rail laid along the travel path of the mold carrier 700 provides independent support and positioning for the mold carrier 600, ensuring that the mold maintains a stable posture during the conveying process. Thus, the two annular guide rails work together to further ensure that the conveyor 600 and the mold carrier 700 avoid bumping due to uneven ground when they travel.

[0038] See Figure 2 The hub frame 521 includes a frame 521a, a cable chain bracket 521b, and a cable chain groove 521c. The cable chain brackets 521b are spaced apart on the frame 521a. The cable chain groove 521c is installed on the cable chain brackets 521b. A slide rail (not shown in the figure) is provided on the cable chain groove 521c. The cable chain 523 is installed in the cable chain groove 521c. The slip ring assembly 522 is slidably connected to the slide rail. When sliding, it drives the cable chain 523 to move in the cable chain groove 521c.

[0039] It should be noted that the cable is neatly stored inside the cable chain 523. In the initial state, the cable chain 523 is bent and placed in the cable chain groove 521c, such as in an "S" or "C" shape. When the transmission device is started, the slip ring assembly 522 moves along the slide rail, causing the cable chain 523 to extend or retract synchronously. The cable chain groove 521c constrains the movement trajectory of the cable chain 523. When extending, the end of the cable chain 523 near the slip ring assembly 522 is gradually released, while the other end remains stable. When retracting, the end of the cable chain 523 near the slip ring assembly 522 moves in the opposite direction, while the other end helps to store excess chain links.

[0040] See Figure 3 The slip ring assembly 522 includes a base 522a and a slip ring 522b. The base 522a is symmetrically provided with pulley groups 522aa on both sides. The pulley groups 522aa slide on the slide rail. The slip ring 522b is disposed on the base 522a and is connected to the base 522a.

[0041] It should be noted that initially, the pulley block 522aa is in a stationary state, and the base 522a and the slide rail remain relatively fixed. When the conveying device 600 is started, the pulley blocks 522aa on both sides of the base 522a reduce resistance through rolling friction and slide synchronously along the slide rail to ensure smooth movement of the base 522a, thereby driving the slip ring 522b to move. The slip ring 522b is connected to the base 522a. During the sliding process, the slip ring 522b can be rotated and adjusted according to external needs to prevent cables or air pipes from breaking due to twisting.

[0042] To further ensure the stability of the cable chain's movement trajectory, positioning wheels 522ab are symmetrically arranged on both sides of the base 522a, and positioning wheel pressure plates 522ac are symmetrically arranged on the inner side of the base 522a above and below the positioning wheels 522ab.

[0043] It should be noted that the positioning wheels 522ab are installed on both sides of the base 522a to limit the movement trajectory of the cable chain 523. When the cable chain 523 slides in the cable chain groove 521c, the positioning wheels 522ab maintain the linear movement of the cable chain 523 through rolling friction, avoiding lateral deviation and preventing it from deviating or shaking during movement. The positioning wheel pressure plate 522ac enhances the clamping force of the positioning wheels 522ab on the cable chain 523, preventing the cable chain 523 from jumping during high-speed movement.

[0044] The aforementioned base, through the synergistic action of pulley block 522aa, positioning wheel 522ab and positioning wheel pressure plate 522ac, forms an efficient dynamic coordination system with cable chain 523 and cable chain groove 521c, ensuring stable transmission of energy supply in the production line, optimizing friction and vibration control, and extending service life.

[0045] Specifically, slip ring 522b is provided with a fixed part 522ba and a rotating part 522bb. The fixed part 522ba is connected to the base 522a through a flange. The rotating part 522bb is rotatably connected to the fixed part 522ba. A driving ring handle 522bc is provided between the rotating part 522bb and the fixed part 522ba. The driving ring handle 522bc is used to ensure the concentricity of the relative rotation of the rotating part 522bb and the fixed part 522ba.

[0046] It should be noted that the fixed part 522ba is fixed to the base 522a via a flange, and the rotating part 522bb is in a stationary or initial position. The cables (air, electricity, water) in the cable chain are connected to the fixed part 522ba. The cable enters from the fixed part 522ba and exits from the rotating part 522bb, and is then transmitted to the moving frame 524 and connected to the mold carrier device 700. When the conveying device 700 slides along the annular guide rail, the rotating part 522bb rotates synchronously with the movement of the moving frame 524, driving the ring handle 522bc to ensure the concentricity of the relative rotation of the rotating part 522bb and the fixed part 522ba, avoiding eccentricity that could cause cable wear or breakage.

[0047] In the aforementioned fully automated annular reflow production equipment for polyurethane product casting, multiple mold carrier devices 700 and multiple moving frames 524 are provided. The mold carrier devices 700 and multiple moving frames 524 are spaced apart on the conveying device 600, which means that multiple mold carrier components can be assembled on the production line, thereby allowing multiple foaming molds to perform foaming operations simultaneously during the conveying process. At the same time, the moving frame and the mold carrier devices are spaced apart on the conveying device, which facilitates the control of the required energy input according to production needs and enhances the system flexibility.

[0048] See Figure 4 , Figure 5 The conveying device 600 includes a conveying module 300 and an assembly module 400. The conveying module 300 includes a circulating chain 310, a driving chain disc 320, a driven chain disc 330, and a drive assembly 340. The circulating chain 310 is connected to the driving chain disc 320 and the driven chain disc 330 respectively. The drive assembly 340 is connected to the driving chain disc 320 and is used to drive the driving chain disc 320 to rotate so that the circulating chain 310 can perform a circular conveying operation. The assembly module 400 includes a fixed pallet 410, a swing assembly assembly 420, and a fixed assembly assembly 430. The swing assembly assembly 420 and the fixed assembly assembly 430 are spaced apart on the circulating chain 310. The fixed pallet 410 is provided with a fixed connection part 411 and a swing connection part 412. The fixed connection part 411 is connected to the fixed assembly assembly 430, and the swing assembly assembly 420 is rotatably connected to the swing connection part 412.

[0049] It should be noted that the fixed connection part 411 of the fixed pallet 410 is connected to the fixed assembly assembly 430, and the swing assembly assembly 420 is rotatably connected to the swing connection part 412 of the fixed pallet 410. Thus, when the circulating chain 310 turns, the change in track curvature causes the swing assembly assembly 420 to swing within a certain rotation range as the circulating chain 310 is subjected to centrifugal force. The centrifugal torque of the fixed pallet 410 is adjusted with the swing assembly assembly 420, which counteracts the centrifugal force and reduces the impact of the centrifugal force on the fixed pallet 410 and the load-bearing object, thereby improving the stability of the transmission. The fixed assembly assembly 430 prevents the relative slippage between the fixed pallet 410 and the circulating chain 310 caused by tension changes or vibration, ensuring that the relative position between the fixed pallet 410 and the circulating chain 310 is fixed, providing stable support for the object carried on the fixed pallet 410, limiting the excessive tilting or slippage of the fixed pallet 410 during the turning process, and enhancing the stability of the overall structure. In this way, the coordinated operation of the swing assembly 420 and the fixed assembly 430 ensures that the fixed pallet 410 can dynamically adapt to the track changes of the circulating chain 310 when turning, avoiding excessive concentrated stress that could cause the circulating chain 310 to derail, and reducing wear on the circulating chain 310 and extending its service life during long-term operation.

[0050] Furthermore, the swing assembly 420 includes a swing fixing member 421 and a swing block 422. The swing fixing member 421 is disposed on the circulating chain 310. The first end of the swing block 422 is hinged to the swing fixing member 421, and the second end of the swing block 422 is hinged to the swing connecting part 412.

[0051] It should be noted that, as mentioned above, the swing fixing component 421 is set on the circulating chain 310, and the swing block 422 has a certain swing amplitude in the horizontal direction through a double hinge design. When the circulating chain 310 turns, the swing block 422 is subjected to centrifugal force. The centrifugal force is outward, and the second end of the swing block 422 tilts outward towards the circulating chain 310, causing the fixed support plate 410 to tilt synchronously, thus counteracting the centrifugal force. The centrifugal force is inward, and the second end of the swing block 422 tilts inward towards the circulating chain 310, ensuring that the fixed support plate 410 is parallel to the track. That is, the swing block 422 can swing adaptively according to the direction of the lateral force generated by the turn, thereby alleviating the direct impact of the centrifugal force on the fixed support plate 410 and avoiding the fixed support plate 410 from tilting or overturning due to excessive centrifugal force.

[0052] Furthermore, the swing fixing member 421 includes a swing connecting screw (not shown in the figure) and a swing mounting protrusion 421a. The swing mounting protrusion 421a is disposed on the circulating chain 310. The swing connecting screw is connected to the swing mounting protrusion 421a. The first end of the swing block 422 is hinged to the swing connecting screw. The swing connecting part 412 includes a swing mounting plate 412a. The swing mounting plate 412a is disposed on one side of the fixed support plate 410. The second end of the swing block 422 is connected to the swing mounting plate 412a through a screw (not shown in the figure).

[0053] It should be noted that, as Figure 5As shown, two swing assembly protrusions 421a are provided, and the two swing assembly protrusions 421a are symmetrically arranged on the circulating chain 310. The swing connecting screw is connected to the two swing assembly protrusions 421a respectively. The first end of the swing block 422 is hinged to the swing connecting screw. Two swing mounting plates 412a are also provided, and the two swing mounting plates 412a are symmetrically arranged on one side of the fixed support plate 410. The second end of the swing block 422 is connected to the two swing mounting plates 412a respectively through screws. Thus, the two swing mounting protrusions 421a serve as the base of the swing system, providing vertical support. The swing connecting screw is connected to the two swing mounting protrusions 421a, and the swing block 422 is hinged to the swing connecting screw, allowing the swing block 422 to rotate around its hinge point, forming a rotary pair. Simultaneously, the two swing mounting protrusions 421a also restrict the vertical displacement of the swing block 422, ensuring that the swing block 422 remains perpendicular to the swing connecting screw during swinging. The swing mounting plate 412a is connected to the swing block via a screw connection, enabling a rotatable connection between the swing block 422 and the fixed support plate 410. In other words, the swing block 422 utilizes a double-hinged design. A virtual hinge is formed, which converts the lateral motion of the fixed pallet 410 under centrifugal force into the rotational motion of the swing block 422. The first end of the swing block 422 rotates around the swing connecting screw, and the second end of the swing block 422 drives the fixed pallet 410 to swing synchronously through the screw. Thus, the swing angle of the swing block 422 is adaptively matched with the turning radius and the magnitude of the lateral force. The lateral force is transmitted to the swing block 422 through the swing mounting plate 412a, and then distributed to the swing mounting protrusion 421a and the circulating chain 310 through the swing connecting screw. The lateral force is converted into the tension of the circulating chain 310, which counteracts the tilting tendency of the fixed pallet 410 and ensures that the pallet remains horizontal when turning.

[0054] The fixed assembly component 430 includes a fixed assembly protrusion 431, which is disposed on the circulating chain 310. The fixed connection part 411 is connected to the fixed assembly protrusion 431 by bolts. The fixed connection part 411 includes a fixed mounting plate 411a, which is disposed on one side of the fixed support plate 410. The fixed mounting plate 411a is connected and fixed to the fixed assembly protrusion 431.

[0055] It should be noted that in this specific facility, two fixed mounting protrusions 431 are also provided. The two fixed mounting protrusions 431 are symmetrically arranged on the circulating chain 310. The fixed mounting protrusions 431 are connected to the fixed connection part 411 by bolts to form a rigid connection. When the fixed assembly component 430 turns, there will be no relative slippage between it and the circulating chain 310. That is to say, the fixed assembly component 430 can be firmly installed on the circulating chain 310. The fixed mounting plate 411a is connected and fixed to the fixed mounting protrusions 431, thereby reducing the displacement of the fixed support plate 410 caused by the vibration or impact of the circulating chain 310. This makes the position of the fixed support plate 410 relative to the circulating chain 310 stable during the turning process and prevents slippage.

[0056] Understandably, as described above, the swing assembly 420 adjusts and balances the centrifugal torque by swinging the swing block 422, reducing the impact of lateral force on the fixed pallet 410 and the load-bearing object when the circulating chain 310 turns. The fixed assembly 430 keeps the relative position of the fixed pallet 410 and the circulating chain 310 fixed through a rigid connection. Thus, the fixed assembly 430 and the swing assembly 420 together achieve dynamic adaptation and stability balance between the fixed pallet 410 and the circulating chain 310. The two work together to provide a buffer for the fixed pallet 410 and its load-bearing object when turning with the circulating chain 310.

[0057] To improve flexibility and stability during turns, the fixed connection 411 and the swing connection 412 are located on the same side of the fixed support plate 410, with the fixed connection 411 being longer than the swing connection 412. This length difference between the fixed connection 411 and the swing connection 412 optimizes the overall center of gravity distribution of the fixed support plate 410 and its supported object, preventing tipping or slippage due to center of gravity shift during turns. The longer fixed connection 411 provides a greater leverage effect, helping to resist centrifugal force and maintain the stability of the fixed support plate 410. The shorter swing connection 412 makes it easier to adjust the connection angle with the swing block 422, reducing the increase in swing amplitude caused by the excessive length of the swing connection 412. Furthermore, this improves flexibility and stability during turns.

[0058] Fixed lugs 311 are spaced apart on the circulating chain 310, and swing assembly protrusions 421a and fixed assembly protrusions 411a are connected to the fixed lugs 311. In this design, the swing assembly assembly 420 and the fixed assembly assembly 430 are connected to the circulating chain 310 through the swing assembly protrusions 421a and the fixed assembly protrusions 411a, respectively. The fixed lugs 311 are spaced apart on the circulating chain 310. In this way, the load-bearing force on the fixed support plate 410 is transmitted to different fixed lugs 311 through the swing assembly assembly 420 and the fixed assembly assembly 430. The fixed lugs 311 disperse the load-bearing force and transmit it to a larger area of ​​the circulating chain, avoiding stress concentration that could damage the circulating chain.

[0059] Sliding elements can be provided on one side of the circulating chain 310 and the bottom surface of the fixed tray 410. During the circular conveying process of the conveying device 600, the sliding elements slide on the circular guide rail.

[0060] In this embodiment, multiple assembly modules 400 are provided, and each assembly module 400 is arranged in a ring along the conveying direction of the circulating chain 310. It can be understood that a mold-carrying device 700 is installed on the fixed tray 410 of the assembly module 400. After the mold is loaded, the mold-carrying device 700 is conveyed together with the assembly module 400 and the conveying module 300.

[0061] See Figure 6 , Figure 7 The mold-carrying device includes a fixing mechanism 100 and a clamping mechanism 200. The fixing mechanism 100 includes a fixing platform 110, a clamping fixing block 120, and a clamping drive module 130. The fixing platform 110 is provided with a lower mold mounting area, and the clamping fixing block 120 is provided with an upper mold mounting area. The clamping drive module 130 is connected to the clamping fixing block 120 and is used to drive the clamping fixing block 120 to perform a mold closing and locking operation in the direction of the lower mold mounting area. The clamping mechanism 200 includes a lifting plate 210, an inflatable component 220, and a lifting drive component 230. The inflatable component 220 is provided on the fixing platform 110 and is located below the lifting plate 210. The inflatable component 220 is connected to the lifting drive component 230 and is used to drive the inflatable component 220 to perform a lifting and pressurizing operation in the direction of the lifting plate 210. The lifting plate 210 is used to clamp in the direction of the lower mold mounting area.

[0062] It should be noted that in the initial state of the foaming mold fixing and locking device, the lower mold mounting area on the fixing platform 110 is empty and is used for subsequent installation of the lower mold. The pressing drive module 130 is located in the initial lifting position. The upper mold mounting area of ​​the pressing fixing block 120 is not installed with the upper mold and maintains the maximum distance of the mold closing stroke with the lower mold mounting area. The pressing drive module 130 is in an unpressurized state and does not apply force to the pressing fixing block 120. The inflation component 220 is in an uninflated state and the lifting drive component 230 is in an unlifted state.

[0063] Furthermore, the clamping drive module 130 is connected to a drive such as a hydraulic cylinder or a pneumatic cylinder, and energy is supplied to the drive through the cable on the moving frame 524 to automate the clamping fixing block 120 to perform mold closing and locking operations in the direction of the lower mold mounting area.

[0064] In use, the lower mold is installed in the lower mold mounting area of ​​the fixed platform 110, ensuring accurate positioning. Then, the upper mold is installed in the upper mold mounting area of ​​the clamping block 120. The alignment accuracy of the upper and lower molds is checked. Next, the external drive, with a set pressure and closing speed, pushes the clamping drive module 130 to move the upper mold mounted on the clamping block 120 to the lower mold mounted in the lower mold mounting area until the mold closing surfaces are completely fitted. During the mold closing process, multiple pressure control levels can be set to pressurize the clamping block 120. Initially, a low-pressure stage is used for slow closing to avoid rapid mold closing and strong impact. Once the molds are in contact, the system switches to a preset high-pressure stage, and the clamping drive module 130 continues to apply force to the clamping block 120, causing the mold closing surfaces to completely fit together. The mold closing force of the upper and lower molds increases gradually. When the mold closing force reaches a preset threshold, the clamping drive module 130 locks with the fixed platform 110 to ensure a tight seal. The mold closing and locking operation is then complete. Furthermore, a pressure sensor can be used to monitor the clamping force during the foaming process in real time. If a decrease in the clamping force is detected, the pressure will be automatically compensated to the set value.

[0065] When foaming occurs in the mold-closed and locked state, the foaming material is confined within the closed space of the mold. When the foaming agent releases gas, the gas cannot escape freely, causing the pressure inside the bubble to rise rapidly. This exerts a huge force on the mold wall, making gaps easily appear on the mold-closing surface, especially at the edges, leading to the overflow of the foaming material and affecting the quality of the product obtained after foaming. The clamping mechanism 200 in this device forms a dynamic sealing system during the foaming process through the coordinated action of the lifting plate 210, the inflation component 220, and the lifting drive component 230. During the foaming process, the internal expansion force of the mold increases, while the mold is continuously subjected to pressure applied by the compression drive module 130. The force exerted by the internal expansion force on the mold wall is transmitted towards the lower mold mounting area and the edge of the mold closing surface. The lifting plate 210 and the inflator 220 located below the lifting plate 210 are compressed. The lifting drive module 230 supports the inflator 220 and connects to it for inflation, causing the inflator 220 to rise and pressurize towards the lifting plate 210. The lifting plate 210 then presses against the lower mold mounting area, ensuring that the mold closing surface remains sealed during the foaming process. After foaming is completed, the inflator 220 is depressurized, the lifting plate 210 returns to its initial position, and the compression drive module 130 unlocks from the fixed platform 110, allowing for smooth separation of the mold. The lifting plate 210 also serves as a component that directly contacts the mold. The inflatable component 220 expands under the drive of the lifting drive component 230, pushing the lifting plate 210 to adhere tightly to the surface of the lower mold during the foaming process and to press the mold firmly, preventing gaps from forming on the mold closing surface and causing the foaming material to overflow.

[0066] See Figure 6 The clamping drive module 130 includes a support frame 131, an opening and closing frame 132, and a locking frame 133. The support frame 131 is connected to the fixed platform 110. One end of the opening and closing frame 132 is hinged to the support frame 131, and the other end of the opening and closing frame 132 is hinged to the locking frame 133. The clamping fixing block 120 is disposed on the opening and closing frame 132 and is located between the support frame 131 and the locking frame 133. When the opening and closing frame 132 rotates relative to the support frame 131, it is used to drive the clamping fixing block 120 to move closer to or further away from the downward mold mounting area. When the locking frame 133 rotates relative to the opening and closing frame 132, it is used to perform locking or unlocking operations with the fixed platform 110.

[0067] Understandably, the opening and closing frame 132 and the locking frame 133 are respectively connected to external drives. Under the external drive, the opening and closing frame 132 rotates relative to the support frame 131. During the mold closing and locking operation, the opening and closing frame 132 drives the pressing and fixing block 120 and the upper mold installed on it to move closer to the lower mold installation area. The locking frame 133 rotates relative to the opening and closing frame 132 in a direction away from the fixed platform 110 to avoid collision with the fixed platform 110. This continues until the upper mold and the lower mold installed on the lower mold installation area are in contact, and the mold closing force reaches the set threshold. Then, the locking frame 133 rotates in a direction closer to the fixed platform 110 and locks with the fixed platform 110. After foaming is completed, the locking frame 133 rotates relative to the opening and closing frame 132 to unlock from the fixed platform 110. The opening and closing frame 132 drives the pressing and fixing block 120 and the upper mold installed on it to move away from the lower mold installation area, and the mold separates.

[0068] It should be noted that the locking frame 133 and the fixed platform 110 can be locked together by means of mechanical buckle, hydraulic self-locking or magnetic adsorption to maintain the mold's closed state.

[0069] To better maintain the mold's closed and locked state, ensuring molding quality and safety, two locking brackets 133 are installed, arranged in parallel. The two parallel locking brackets 133 can distribute the load, reducing the force on each bracket and preventing deformation caused by single-point stress. This results in a more stable structure and increased stability of the mold's closing and locking. When the mold is large, the parallel design may facilitate operation, such as locking from both sides simultaneously. The two locking brackets can cover a wider area, reducing the risk of warping or misalignment. Furthermore, if one locking bracket 133 malfunctions, the other can still function, improving reliability.

[0070] Furthermore, two clamping and fixing blocks 120 are provided, spaced apart on the opening and closing frame 132. In this specific embodiment, the clamping and fixing blocks 120 serve two purposes: firstly, to fix the upper mold, and secondly, during the mold closing and locking operation, to apply pressure to the mold after it is closed, as the clamping drive module 130 applies pressure. With two clamping and fixing blocks 120 positioned at different locations on the opening and closing frame 132, when the frame closes towards the lower mold mounting area, the two clamping and fixing blocks 120 clamp different positions on the mold, applying force to multiple points and increasing the contact area between the mold and the clamping blocks. This improves the overall stability of the device and reduces vibration or displacement. During the foaming molding process, the mold experiences internal stress due to the expansion and pressure of the foamed material. The two clamping and fixing blocks 120 can balance these stresses, reducing the risk of mold warping.

[0071] To accommodate molds of different sizes, the opening and closing frame 132 is provided with an adjustment groove 132a. Two clamping and fixing blocks 120 are connected to the adjustment groove 132a by bolt fasteners. In this way, the position of the two clamping and fixing blocks 120 can be adjusted according to the mold of different sizes for mold alignment and installation. At the same time, it can also better balance the internal stress of different molds and improve the flexibility of the device application.

[0072] See Figure 7 The lifting drive component 230 includes an inflatable support plate 231, which is mounted on the fixed platform 110 and located below the inflatable component 220. An inflation channel 231a is provided on the inflatable support plate 231, which is connected to the inflatable component 220.

[0073] It should be noted that during the foaming process, the internal expansion force of the mold increases, and the expansion force exerts a force on the inner wall of the mold. The lifting plate 210 and the inflatable component 220 located below the lifting plate 210 are compressed. The lifting drive component 230 inflates the inflatable component 220 through the inflation channel 231a of the inflation support plate 231 according to the pressure on the inflatable component 220. Due to the support of the inflation support plate 231, the inflatable component 220 is kept in the direction of the lifting plate 210 for lifting and pressurization, which has a guiding effect on the deformation of the inflatable component 220, keeping the inflatable component 220 expanding in the direction of the lifting plate 210. The lifting plate 210 then presses against the lower mold mounting area, so that the mold closing surface remains sealed during the foaming process.

[0074] In this specific implementation, the inflatable support plate 231 has a smaller outer dimension than the inflatable component 220, and several concave notches 231b are provided on both opposite sides of the inflatable support plate 231. (See reference...) Figure 1 , Figure 3 The outer dimensions of the support plate are smaller than those of the inflatable component 220. Support gaps are left at both ends of the inflatable component 220, allowing the inflatable component 220 to have greater freedom when it expands. When the inflatable component 220 expands, the area not covered by the inflatable support plate 231 can have a larger deformation space. The inflatable support plate 231 only restricts the deformation of a part of the inflatable component 220. The unsupported area of ​​the inflatable component 220 is not constrained by the inflatable support plate 231, reducing the restriction on the overall deformation of the inflatable component 220 and avoiding excessive constraint that could lead to stress concentration or breakage of the inflatable component 220. The inflatable support plate 231 has several concave notches 231b on both opposite sides. When the inflatable component 220 expands and deforms, it is supported and constrained on both sides of the inflatable support plate 231, while a buffer structure is formed at the concave notches 231b. This allows the inflatable component 220 to expand upwards and uniformly as a whole, avoiding shape deviation caused by instantaneous disorderly expansion. The deformation is more controllable. After the inflatable component 220 deforms, it applies more uniform pressure to the lifting plate 210 for lifting.

[0075] Furthermore, two inflatable components 220 are provided, which are located on opposite sides below the lifting plate 210. The two inflatable components 220 apply a uniform lifting force to the lifting plate 210 from both sides, avoiding the lifting plate 210 from tilting due to force on one side, making the mold lifting more stable, and the pressure distribution on the contact surface between the lifting plate 210 and the mold more uniform, avoiding excessive local pressure that may affect the effective sealing of the mold closing surface.

[0076] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
