Description

TECHNICAL FIELD

[0001] The present application relates to the field of seal processing, in particular to a seal processing equipment and method. BACKGROUND

[0002] In the field of mechanical industry, the seal composed of metal framework and polymer elastomer is a key element to ensure the sealing performance of rotating or reciprocating parts. The production of such seal widely adopts insert molding process, and the core processing equipment is usually a multi-layer hot press or a special molding machine. The process places the prefabricated metal framework into the mold cavity, and injects the unvulcanized elastomer material under high temperature and pressure, so that the elastomer material connects the framework in the cavity and crosslinks and solidifies, thereby forming a stable integrated seal.

[0003] Currently, the focus and optimization direction of such equipment and process mainly concentrate on the efficiency and precision improvement of the front-end processes such as feeding, molding and vulcanization. However, in the crucial downstream unloading and demolding stage, the commonly used solutions still have significant bottlenecks. Typically, after the vulcanization molding cycle is completed, the workpiece is removed from the mold by manual or simple mechanical device. Specifically, the operator needs to open the mold, use tools to pry and peel off the workpiece tightly wrapped on the lower mold core, or manually take it out from the complex mold cavity. This process not only constitutes a speed bottleneck of the production line, but also has safety risks due to the contact with high-temperature workpieces, and the instability of manual operation easily leads to quality problems such as product scratching and deformation. SUMMARY

[0004] In order to improve the processing efficiency, the present application provides a seal processing equipment and method.

[0005] In the first aspect, the present application provides a seal processing equipment, which adopts the following technical scheme: A seal processing equipment, comprising a moving table, an upper mold, a positioning mold, a lower mold, a ejection mold and a driving assembly, the lower mold is fixedly connected to the upper end of the moving table, the sliding direction of the moving table is horizontal, the upper mold and the positioning mold slide up and down above the lower mold, the positioning mold is arranged between the upper mold and the lower mold, the upper end of the positioning mold is provided with a positioning slot, the positioning slot is used for embedding the framework, the bottom of the positioning slot is provided with a positioning opening, the upper end of the lower mold is fixedly connected with a forming block, the forming block is used for extending into the positioning opening, the lower end of the upper mold is provided with a forming slot, the slot wall of the forming slot, the inner wall of the positioning opening and the upper end of the forming block jointly form a forming cavity, the ejection mold slides up and down below the positioning mold, the upper end of the ejection mold is fixedly connected with an ejection block, the ejection block is used for ejecting material into the positioning opening, and the driving assembly is used for driving the upper mold, the positioning mold, the moving table and the ejection mold to move.

[0006] By adopting the above technical solution, after vulcanization molding, the upper mold moves upward and separates from the positioning mold, the positioning mold moves upward and separates from the lower mold, the moving table drives the lower mold to move horizontally, making room for the vertical channel, the ejector mold moves upward, and the ejector block passes through the positioning hole to eject the workpiece; this replaces the traditional manual prying method, improves the efficiency of demolding and unloading, thereby improving the overall work efficiency, while also improving the safety of operation, the workpiece is less likely to be scratched or deformed during demolding, and improves the consistency and stability of product quality.

[0007] Preferably, the depth of the positioning groove is equal to the thickness of the skeleton, and the lower end of the upper mold abuts against the upper end of the positioning mold and the upper end of the skeleton.

[0008] By adopting the above technical solutions, it is ensured that the skeleton is precisely confined within the predetermined plane during the mold closing process, preventing it from tilting or shifting under pressure, thus guaranteeing the connection quality between the skeleton and the elastomer. The upper mold simultaneously presses the positioning mold and the skeleton together, forming an end face seal, which effectively prevents the high-pressure molten elastomer material from overflowing between the upper mold and the positioning mold and generating flash, directly improving the dimensional accuracy and appearance quality of the product, while reducing subsequent trimming processes and further improving overall production efficiency.

[0009] Preferably, the driving component includes a first driving member, which includes a first driving source and a limiting block. There are two first driving members, which are respectively located on both sides of the positioning mold. The first driving source drives the limiting block to slide up and down. The limiting block has a limiting groove at one end facing the positioning mold, and both ends of the limiting block are located in the limiting groove.

[0010] By adopting the above technical solution, a rigid and controllable vertical motion guide and limiting function is provided for the positioning mold, ensuring that the positioning mold has a precise path and no shaking or deflection during the lifting process. When the upper mold moves upward, the limiting block can separate the positioning mold from the temporary connection with the upper mold, reducing the probability of the positioning mold moving with the upper mold. When the limiting block moves upward, it can separate the positioning mold from the lower mold, improving the coordination, timing accuracy and overall automation cycle stability of the entire demolding action sequence.

[0011] Preferably, the width direction of the limiting groove is vertical, and the width of the limiting groove is greater than the thickness of the positioning mold.

[0012] By adopting the above technical solution, it is ensured that the positioning mold can smoothly enter or move away from the limiting groove when it moves with the moving table connected to the lower mold. Due to the overflow and solidification of the elastomer material, the upper mold and the positioning mold are mechanically interlocked. After the positioning mold moves with the upper mold, due to the gravity of the positioning mold and the obstruction of the limiting groove, the positioning mold separates from the upper mold and falls back. After the positioning mold falls, it vibrates, and the frame is locked in the positioning groove due to thermal expansion and contraction. The vibration of the positioning mold makes the workpiece loose in the positioning groove, which breaks the static friction and vacuum adsorption state between the workpiece and the mold cavity, making it easier to demold and improve production efficiency.

[0013] Preferably, it also includes an auxiliary plate, which is disposed above the positioning mold, and the lower end surface of the auxiliary plate is used to abut against the upper end surface of the positioning mold.

[0014] By adopting the above technical solution, when the ejector block moves upward to eject the workpiece, the auxiliary plate, as an adjustable dynamic clamping mechanism, can effectively counteract the frictional force suddenly released between the workpiece and the positioning groove and the elastic energy generated by the deformation of the elastomer at the moment of ejection. This suppresses the upward jumping, tilting or accidental ejection of the workpiece, ensuring that the workpiece leaves the mold in a stable and controllable manner. This solves the problem of downtime caused by workpiece splashing and jamming in the automated ejection process, and greatly improves the stability, safety and cycle efficiency of continuous production.

[0015] Preferably, an electromagnet is fixedly connected to the auxiliary plate, and the electromagnet is used to attract the skeleton.

[0016] By adopting the above technical solution, the electromagnet adsorption frame connects all the workpieces to the auxiliary plate, and then they are transported together to the unloading and stacking area, which facilitates unloading. There is no need to manually push the workpieces into the collection box, which reduces the wind direction of material leakage during manual operation, reduces the wind direction of burns to operators, reduces the wind direction of deformation and damage to workpieces caused by pushing them, and improves the production efficiency of workpieces.

[0017] Preferably, the upper end of the top material block is used to abut against the skeleton, the top material block is provided with a clearance opening, the clearance opening is used to avoid the elastic body, and the length of the top material block is equal to the thickness of the positioning mold.

[0018] By adopting the above technical solution, during ejection, the ejector block can precisely extend into the thickness space of the positioning mold. Its top end only forms rigid, full-circumferential contact and support with the lower end face of the metal frame, while the clearance ensures that the elastomer part is in a free state without contact or interference throughout the ejection process. This achieves direct and efficient application of ejection force to the rigid frame, while completely avoiding any squeezing, scratching, or deformation of the precision and soft elastomer part by the ejector block. Thus, while ensuring the absolute reliability of the demolding action, it perfectly protects the product's key sealing function and appearance integrity, significantly improving product yield. The length of the ejector block is equal to the thickness of the positioning mold, allowing the workpiece to be removed from the positioning groove, facilitating unloading.

[0019] Preferably, the driving assembly includes a second driving member, which includes a second driving source and a limiting plate. There are two second driving members, which are respectively located on both sides of the upper mold. The second driving source drives the limiting plate to slide up and down. An extension block is fixedly connected to the end of the upper mold facing the limiting plate. An extension groove is provided at the upper end of the limiting plate for the extension block to be embedded.

[0020] By adopting the above technical solution, during non-working or maintenance phases, the mechanism can actively rise and securely lock the upper mold at a preset safe height, preventing it from slipping due to its own weight or unexpected circumstances, thus avoiding safety hazards and equipment damage. At the start of the work cycle, it can precisely control the unlocking and lowering process, ensuring that the upper mold closes in a stable posture. This effectively solves the problems of positioning drift, vibration, and safety risks that exist when large upper molds are frequently started and stopped or suspended for long periods of time, significantly improving the safety, stability, and service life of the equipment.

[0021] Preferably, it also includes a support and abutment wheels. The support includes a vertical column and a horizontal column. The horizontal column is fixedly connected to the outer wall of the vertical column and is located above the upper mold. The abutment wheels are coaxially rotatably connected to the outer wall of the horizontal column, and the lower end of the abutment wheels is used to abut against the upper end of the upper mold.

[0022] By adopting the above technical solution, the abutment wheel limits the upper mold and clamps the upper mold together with the second drive component, preventing the upper mold from falling accidentally and ensuring the personal safety of the operator.

[0023] Secondly, this application provides a method for processing a sealing component, which adopts the following technical solution: A method for processing a sealing component includes the following steps: After molding is complete, the drive component drives the moving table to slide horizontally above the top mold; The drive component drives the upper mold to move upward, and the upper mold drives the positioning mold to move synchronously. Due to the gravity of the positioning mold and the limitation of the limiting groove, the positioning mold falls back to the upper end of the lower mold. The driving component drives the positioning module to move upward; The drive component drives the moving stage to cause the lower mold to slide horizontally away from the positioning mold; The driving component drives the positioning module to move downwards; Place an auxiliary plate on the upper end of the positioning mold; The drive component drives the ejector mold to move upward, causing the ejector block to extend into the positioning port to eject the material; Remove the auxiliary plate and unload the workpiece; The drive component drives the ejector die to move downwards and the positioning die to move upwards; The drive component drives the moving stage to slide horizontally, causing the lower mold to move directly below the positioning mold; Clean the positioning mold, lower mold, and upper mold; The driving component drives the positioning mold to slide downward, so that the positioning mold abuts against the lower mold, and the forming block goes deep into the positioning hole; Embed the skeleton into the positioning groove; The driving component drives the upper mold to slide downwards, causing the upper mold to abut against the positioning mold; Fill the upper part of the mold with the rubber material; The drive component drives the moving table to move to the forming area for forming.

[0024] By adopting the above technical solution, the material feeding process does not require manual intervention, which improves the material feeding efficiency, reduces the waiting time for material loading, and improves the overall processing efficiency.

[0025] In summary, this application includes at least one of the following beneficial technical effects: After vulcanization molding, the upper mold moves upward and separates from the positioning mold, the positioning mold moves upward and separates from the lower mold, the moving table drives the lower mold to move horizontally, making room for the vertical channel, the ejector mold moves upward, and the ejector block passes through the positioning hole to eject the workpiece; this replaces the traditional manual prying method, improves the efficiency of demolding and unloading, thereby improving the overall work efficiency, while also improving the safety of operation, the workpiece is less likely to be scratched or deformed during demolding, and improves the consistency and stability of product quality; This ensures that the positioning mold can smoothly enter or move away from the limiting groove as it moves with the moving table connected to the lower mold. Due to the overflow and solidification of the elastomer material, the upper mold and the positioning mold are mechanically interlocked. After the positioning mold moves with the upper mold, due to the gravity of the positioning mold and the obstruction of the limiting groove, the positioning mold separates from the upper mold and falls back. After the positioning mold falls, it vibrates, and the skeleton expands and contracts due to heat and cold, locking itself in the positioning groove. The vibration of the positioning mold causes the workpiece to loosen in the positioning groove, which breaks the static friction and vacuum adsorption state between the workpiece and the mold cavity, making it easier to demold and improving production efficiency. When the ejector block moves upward to eject the workpiece, the auxiliary plate, as an adjustable dynamic clamping mechanism, can effectively counteract the frictional force suddenly released between the workpiece and the positioning groove and the elastic energy generated by the deformation of the elastomer at the moment of ejection. This suppresses the upward jumping, tilting or accidental ejection of the workpiece, ensuring that the workpiece leaves the mold in a stable and controllable manner. This solves the problem of downtime caused by workpiece splashing and jamming in the automated ejection process, and greatly improves the stability, safety and cycle efficiency of continuous production.

The misalignment plate 82 faces the feeding plate 81. The connecting post 83 slides within the waist-shaped opening 812. A limiting ring 831 is fixedly connected to the outer wall of the connecting post 83. The limiting ring 831 abuts against the feeding plate 81 on the side away from the misalignment plate 82. The diameter of the limiting ring 831 is larger than the width of the waist-shaped opening 812. A handle 84 is located on the outer periphery of the feeding plate 81. The handle 84 is fixedly connected to the misalignment plate 82 on the side facing the feeding plate 81. There are two handles 84, which are respectively located on both sides of the feeding plate 81. The feeding plate 81 and the misalignment plate 82 are provided with limiting openings 813 at their four corners. The limiting openings 813 are used to avoid the limiting post 324. The limiting post 324 limits the feeding plate 81.

[0059] Reference Figure 5 and Figure 12 The misaligned plate 82 has a movable opening 822 at one end facing the limiting post 324.

[0060] Reference Figure 11 and Figure 12 The length direction of the movable opening 822 is parallel to the length direction of the waist-shaped opening 812. The movable opening 822 is used for the insertion of the limiting post 324. When the handle 84 pushes the misalignment plate 82 to move, so that the limiting post 324 extends into the movable opening 822, the feeding opening 811, the misalignment opening 821 and the positioning groove 321 are aligned.

[0061] The implementation principle of a sealing component processing equipment according to an embodiment of this application is as follows: After molding, the moving table 22 moves to the transfer area 213, and the upper mold 31 moves upward. Due to material overflow, the positioning mold 32 moves synchronously. The spring 91 pushes the positioning mold 32 upward through the mounting column 92 until the positioning mold 32 abuts against the downward-facing groove wall of the limiting groove 5521. At this point, there is no interaction force between the spring 91 and the positioning mold 32. The positioning mold 32 falls downward under the action of gravity and the abutment of the limiting block 552. The mounting column 92 is embedded in the groove 325, and the vibration auxiliary frame of the positioning mold 32 loosens in the positioning groove 321. Spring 91 creates a gap between positioning mold 32 and lower mold 33, reducing the probability of damage to the elastomer caused by compression from lower mold 33. Positioning mold 32 moves upward, lower mold 33 moves to forming area 212, positioning mold 32 moves downward to reset, auxiliary plate 61 is placed on positioning mold 32, electromagnet 63 is energized to generate attraction force on the skeleton, ejector mold 4 moves upward, ejector block 41 abuts against the skeleton. Due to the clamping between the skeleton and positioning groove 321, the vibration above may not have loosened part of the skeleton. Ejector block 41 pushes the entire positioning mold 32 upward through the skeleton, limiting groove 5521 facing downward. When the movement of the positioning mold 32 is limited, and the force on the skeleton is greater than the friction between the skeleton and the positioning groove 321, the skeleton and the groove wall of the positioning groove 321 separate. Due to the obstruction of the auxiliary plate 61, the workpiece is not easily bounced away. The electromagnet 63 stably attracts the workpiece, the protective opening 611 avoids the elastic body, and the moving auxiliary plate 61 realizes the transfer of all workpieces. The top mold 4 moves downward to reset, the positioning mold 32 moves upward, the lower mold 33 moves to the transfer area 213, and the positioning mold 32 moves downward. At this time, the mounting column 92 is embedded in the groove 325. The operator places the loading part 8 above the positioning mold 32 and operates. While the operator holds the handle 84 and applies downward force, the misalignment plate 82 slides horizontally. The limiting post 324 extends into the movable opening 822 to limit the sliding of the misalignment plate 82. The skeleton falls into the positioning groove 321 through the misalignment opening 821. The loading part 8 is removed from the top. The spring 91 pushes the positioning mold 32 to move upward. The vibration of the positioning mold 32 assists the skeleton to be fully embedded in the positioning groove 321, improving the loading efficiency. While the upper mold 31 moves downward, it further flattens the skeleton. The spring 91 retracts. Finally, the upper mold 31, the positioning mold 32 and the lower mold 33 are closed. The moving table 22 transfers the mold together to the forming area 212.

[0062] This application also discloses a method for processing a sealing component. (Refer to...) Figures 1-4 A method for processing a sealing component includes the following steps: After molding is completed, the drive component 5 drives the moving stage 22 to slide horizontally above the top mold 4; The drive component 5 drives the upper mold 31 to move upward, and the upper mold 31 drives the positioning mold 32 to move synchronously. Due to the gravity of the positioning mold 32 and the limitation of the limiting groove 5521, the positioning mold 32 falls back to the upper end of the lower mold 33. Drive component 5 drives positioning module 32 to move upward; Drive component 5 drives the moving stage 22 to move the lower mold 33 horizontally away from the positioning mold 32; Drive component 5 drives positioning module 32 to move downward; An auxiliary plate 61 is placed on the upper end of the positioning mold 32; Drive component 5 drives the ejector mold 4 to move upward, causing the ejector block 41 to extend into the positioning port 322 to eject the material; Remove the auxiliary plate 61 and unload the workpiece; Drive component 5 drives the ejector mold 4 to move downward and the positioning mold 32 to move upward; The driving component 5 drives the moving stage 22 to slide horizontally, causing the lower mold 33 to move directly below the positioning mold 32; Clean the positioning mold 32, lower mold 33 and upper mold 31; The driving component 5 drives the positioning mold 32 to slide downward, so that the positioning mold 32 abuts against the lower mold 33, and the forming block 331 penetrates into the positioning port 322; The skeleton is embedded in the positioning groove 321; The driving component 5 drives the upper mold 31 to slide downward, so that the upper mold 31 abuts against the positioning mold 32; Insert the adhesive material into the upper part of the upper mold 31; The drive component 5 drives the moving stage 22 to move to the forming area 212 for forming.

[0063] The implementation principle of the sealing component processing method in this application embodiment is as follows: the blanking process does not require manual intervention, which improves the blanking efficiency, reduces the waiting time for loading, and improves the overall processing efficiency.

[0064] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
