Description

Technical Field

[0001] This invention relates to the field of shoe sole demolding technology, and more specifically, to a demolding auxiliary mechanism for a shoe sole hydraulic press. Background Technology

[0002] Demolding of shoe soles using a hydraulic press refers to the process where, after the shoe sole material is pressed and heated in a mold through hydraulic pressure, vulcanization, and molding, the hydraulic press opens the mold and then, through auxiliary structures such as a hydraulic ejection mechanism, ejector rod, angled ejector core puller, or negative pressure adsorption, smoothly and completely separates and ejects the molded shoe sole from the upper and lower mold cavities. At the same time, special release agents are sprayed and residual adhesive in the mold is cleaned during production to prevent the shoe sole from sticking to the mold, deforming, or being pulled, and to ensure the integrity of the shoe sole's appearance and pattern.

[0003] A search revealed that publication number (CN117921958A) discloses a shoe sole demolding device for processing work shoes. The device describes "a shoe sole demolding platform, with a lower mold cavity formed at the longitudinal center of the upper surface of the platform. Fixed plates are fixedly installed at the transverse center of both the front and rear sides of the upper surface of the platform. First T-shaped grooves are formed at the transverse center of the opposite surfaces of the two fixed plates. Sliding devices are installed inside the two first T-shaped grooves, and moving plates are installed on the sliding devices. An upper mold is fixedly installed on the lower surface of the moving plate at a position corresponding to the lower mold cavity. Rectangular grooves are formed on both the front and rear sides of the lower surface of the moving plate. Cold air reduces the temperature inside the lower mold cavity by lowering the temperature of the two side grooves, the rectangular connecting holes, and the bottom groove, thereby accelerating the cooling and molding of the shoe sole and improving the working efficiency and practicality of the device."

[0004] When using the above technology, the following technical problems were found in the existing technology: In the production process, the above-mentioned shoe sole hydraulic press uses a single mold base for operation, that is, the next feeding and extrusion operation can only be carried out after the material extrusion, cooling and shaping, demolding and cleaning are completed. This single mold base operation mode has obvious production bottlenecks. When the mold base is extruding and shaping, the equipment is in an idle waiting state and cannot carry out demolding, cleaning and material preparation work at the same time, resulting in slow production rhythm and low production efficiency.

[0005] Based on this, the present invention discloses a demolding auxiliary mechanism for a shoe sole hydraulic press. Summary of the Invention

[0006] To address the issue raised in the background art, where shoe sole hydraulic presses operate using a single mold base during production—meaning that material extrusion, cooling, shaping, demolding, and cleaning must be completed before the next extrusion operation can begin—this single-mold base operation mode presents a significant production bottleneck.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example like Figures 1-10 As shown, the system includes a base frame 1, with a main frame 2 fixedly connected to the upper end of the base frame 1. Four support columns 3 are fixedly connected to the upper end of the main frame 2, and a top frame 4 is fixedly connected to the upper end of the four support columns 3. Two movable mold bases 5 are slidably connected to the inner side of the main frame 2, with their ends fixedly connected. Forming grooves 6 are symmetrically formed on the inner side of each of the two movable mold bases 5. Forming blocks 7 are provided on the inner side of each forming groove 6. A lifting guide rod 8 is fixedly connected to the lower end of each forming block 7. The moving mold base 5 is slidably connected to the moving mold base 5. The lower ends of two adjacent lifting guide rods 8 are fixedly connected to the ejector plate 9. A first spring 10 is provided on the outer side of the lifting guide rod 8. The two ends of the first spring 10 are fixedly connected to the moving mold base 5 and the ejector plate 9, respectively. A moving mechanism is provided between the main frame 2 and the moving mold base 5. An ejector mechanism is provided on the inner side of the bottom frame 1. A hydraulic press mechanism is provided in the middle of the top frame 4. An air intake mechanism is provided between the main frame 2 and the moving mold base 5. A cutting mechanism is symmetrically provided on the upper end of the main frame 2.

[0023] During operation, the material is discharged into the inner side of the forming tank 6 through the discharge component in the hydraulic press mechanism, and then the material inside the forming tank 6 is squeezed by the hydraulic press mechanism. Before extrusion, the moving die 5 located in the middle of the main frame 2 is cooled by the air outlet mechanism. After extrusion, the two moving die 5 are moved by the moving mechanism, so that the moving die 5 with material is moved to the upper end of the top pressing mechanism, and the moving die 5 without material is moved to the middle of the main frame 2. At the same time, the air outlet mechanism heats the moving die 5 located at the upper end of the ejection mechanism, so that the moving die 5 is heated to the normal temperature. Subsequently, the ejection mechanism pushes the ejection plate 9, which in turn moves the two forming blocks 7 upward through the lifting guide rod 8, thereby ejecting the extruded shoe sole from the inside of the forming groove 6. After ejection, the ejection mechanism resets, and the forming blocks 7 are reset by the elasticity of the first spring 10.

[0024] like Figure 3 As shown, a servo motor 11 is fixedly connected to the end of the main frame 2, and a threaded rod 12 is fixedly connected to the output end of the servo motor 11. The threaded rod 12 is located inside the main frame 2 and is rotatably connected to the main frame 2. Threaded grooves 13 are opened on the inner sides of the two movable mold bases 5. The threaded rod 12 is located inside the threaded groove 13 and is threadedly connected to the threaded groove 13.

[0025] During operation, the servo motor 11 is started, causing the output end of the servo motor 11 to drive the threaded rod 12 to rotate. The threaded rod 12 is threadedly connected to the threaded groove 13, thereby driving the two threaded grooves 13 to move inside the main frame 2. This moves the extruded moving die 5 to the upper end of the ejection mechanism, and the moving die 5 that needs to be fed to the lower end of the hydraulic press mechanism.

[0026] like Figures 1-5 As shown, the ejection mechanism includes two ejection cylinders 14. The ejection cylinders 14 are symmetrically fixedly connected to the inner side of the lower end of the bottom frame 1, and the extension and retraction ends of the ejection cylinders 14 are fixedly connected to the ejection top plate 15.

[0027] During operation, the ejector cylinder 14 is activated, causing the telescopic end of the ejector cylinder 14 to move the ejector plate 15 upward. This, in turn, pushes the ejector connecting plate 9 upward through the ejector plate 15. Consequently, the ejector connecting plate 9 moves the two forming blocks 7 upward through the two lifting guide rods 8, thus ejecting the forming blocks 7 inside the forming groove 6. After ejection, the telescopic end of the ejector cylinder 14 returns to its initial position. At this time, the elasticity of the first spring 10 pushes the ejector connecting plate 9 downward, causing the ejector connecting plate 9 to move the two forming blocks 7 back to their original position through the two lifting guide rods 8.

[0028] like Figures 1-3 As shown, the hydraulic press mechanism includes a main hydraulic press 17. The main hydraulic press 17 is fixedly connected to the middle of the top frame 4. A pressing connecting rod 18 is fixedly connected to the telescopic end of the main hydraulic press 17. A pressing plate 19 is fixedly connected to the lower end of the pressing connecting rod 18 away from the main hydraulic press 17. Four guide columns 16 are fixedly connected to the lower end of the middle of the top frame 4. One end of the four guide columns 16 away from the top frame 4 is fixedly connected to the main frame 2. The pressing plate 19 is slidably connected to the four guide columns 16. Discharge components are symmetrically arranged at both ends of the pressing plate 19.

[0029] During operation, when it is necessary to shape the material inside the forming tank 6, the material is discharged into the inside of the forming tank 6 through the discharge component. Then, the main hydraulic press 17 is started, which causes the telescopic end of the main hydraulic press 17 to move the pressing connecting rod 18 downward, thereby causing the pressing connecting rod 18 to move the pressing plate 19 downward, thus squeezing out the excess material inside the forming tank 6.

[0030] like Figures 1-2 As shown, the air intake mechanism includes an air intake pipe 21 and an exhaust pipe 22. Three air intake pipes 21 and three exhaust pipes 22 are symmetrically fixedly connected to the inner sides of both ends of the main frame 2. A switch valve is provided at the end of the air intake pipe 21 and the exhaust pipe 22 near the main frame 2. Ventilation slots 23 are symmetrically opened at both ends of the movable mold base 5.

[0031] During operation, when it is necessary to shape the material inside the forming tank 6, the switch valve on the middle air inlet pipe 21 is opened, and then cold air is delivered to the inside of the air inlet pipe 21. The cold air enters the inside of the moving mold base 5 through the ventilation slot 23 and is discharged through the exhaust pipe 22, thereby accelerating the cooling of the material inside the forming tank 6 and thus accelerating the shaping time. When the molding groove 6 moves to the upper end of the ejection mechanism, the switch valves of the air inlet pipe 21 and the exhaust pipe 22 near the two ends of the moving mold base 5 are opened, thereby delivering hot air to the inside of the moving mold base 5, so that the temperature of the moving mold base 5 returns to normal, making it easier to eject the shoe sole from the inside of the molding groove 6 later.

[0032] like Figures 1-4 As shown, the discharge assembly includes a fixed bracket 24. Two fixed brackets 24 are symmetrically arranged at both ends of the pressing plate 19. The four fixed brackets 24 are fixedly connected to four guide columns 16. Positioning shafts 25 are also symmetrically arranged at both ends of the pressing plate 19. Both ends of the positioning shafts 25 are located inside the fixed brackets 24 and are rotatably connected to the fixed brackets 24. A discharge sleeve 26 is rotatably connected to the outer side of the positioning shafts 25. A discharge pipe 27 is fixedly connected to the lower end of the discharge sleeve 26. A conveying connection box 28 is fixedly connected to the end of the discharge pipe 27. A feed hose 29 is fixedly connected to the end of the conveying connection box 28 away from the discharge pipe 27. The discharge pipe 27, the conveying connection box 28, and the feed hose 29 are interconnected internally.

[0033] A flipping block 30 is fixedly connected to the outer side of the discharge rotating sleeve 26, and a second spring 31 is symmetrically arranged on the outer side of the positioning rotating shaft 25. The two ends of the second spring 31 are fixedly connected to the discharge rotating sleeve 26 and the fixed bracket 24, respectively.

[0034] During operation, when the pressing plate 19 moves upward, it pushes the flipping block 30, causing the flipping block 30 to drive the discharge sleeve 26 to rotate outside the positioning shaft 25, thereby rotating the discharge pipe 27 to the center of the upper end of the forming groove 6, and then conveying the material to the inside of the material conveying box 28 through the feeding hose 29. The material is discharged through the discharge pipe 27 and enters the inside of the forming groove 6. When the pressing plate 19 moves downward, the positioning shaft 25 drives the discharge sleeve 26 to rotate, so that the ends of the two discharge pipes 27 move away from each other, and the feed hose 29 pulls the discharge pipe 27 to prevent the discharge pipe 27 from rotating 90 degrees.

[0035] like Figures 6-9 As shown, the cutting mechanism includes a cutting bracket 32. The cutting bracket 32 ​​is symmetrically arranged on the upper end of the main frame 2. The cutting bracket 32 ​​is fixedly connected to the support column 3. The upper end of the cutting bracket 32 ​​is fixedly connected to a cutting cylinder 33. The telescopic end of the cutting cylinder 33 is fixedly connected to a cutting connecting plate 34. The lower end of the cutting connecting plate 34 is fixedly connected to a connecting block 35. The lower end of the cutting bracket 32 ​​is provided with a cutting frame 36. The cutting frame 36 is fixedly connected to the connecting block 35. The inner side of the cutting frame 36 is fixedly connected to a cutter 37. The lower end of the cutting frame 36 is fixedly connected to a limiting push plate 40. The limiting push plate 40 is fixedly connected to the cutter 37.

[0036] The upper end of the cutting frame 36 is symmetrically fixedly connected with guide blocks 39, and the inner side of the lower end of the cutting bracket 32 ​​is symmetrically provided with guide grooves 38. The guide blocks 39 are located inside the guide grooves 38 and are slidably connected with the guide grooves 38.

[0037] Multiple cleaning brackets 41 are fixedly connected to the inner side of the cutting frame 36, and a cleaning cloth 42 is provided on the outer side of the cleaning brackets 41.

[0038] During operation, when the moving mold base 5 moves to the upper end of the ejection mechanism, the extension end of the cutting cylinder 33 drives the cutting connecting plate 34 to move, which in turn causes the cutting connecting plate 34 to drive the connecting block 35 and the cutting frame 36 to move synchronously. This causes the cutting frame 36 to drive the cutter 37 to cut off the material extruded from the end of the moving mold base 5. After the cutting is completed, the ejection mechanism ejects the sole. The cutting frame 36 and the limiting push plate 40 drive the cleaning bracket 41 and the cleaning cloth 42 to continue moving, thereby pushing the sole to the outside of the main frame 2. The cleaning cloth 42 then drives the moving mold base 5 and the forming pressure block 7 to clean.

[0039] Working principle: First, the material is fed through the fixed brackets 24 at both ends of the main hydraulic press 17. When the pressing plate 19 is reset upward, it will push the flipping block 30 to drive the discharge rotating sleeve 26 to rotate, so that the discharge pipe 27 is aligned with the forming groove 6 on the moving mold base 5. Then the material is accurately discharged into the inside of the forming groove 6 through the feeding hose 29, the conveying connection box 28 and the discharge pipe 27. After the material is fed, start the main hydraulic press 17. The telescopic end of the main hydraulic press 17 drives the pressing connecting rod 18 and the pressing plate 19 to move downward, extruding and shaping the material in the forming groove 6, while extruding out the excess scrap material. Before extrusion and shaping, the moving mold base 5 located in the middle of the main frame 2 is cooled through the air inlet pipe 21 and the exhaust pipe 22. The switch valve on the middle air inlet pipe 21 is opened, and the cold air enters the interior of the moving mold base 5 through the air vent 23 and is discharged through the exhaust pipe 22, which accelerates the cooling and shaping of the material. After extrusion, the servo motor 11 is started, which drives the threaded rod 12 to rotate. Through the threaded engagement between the threaded rod 12 and the threaded groove 13, the two moving mold bases 5 are moved to the inside of the main frame 2. The moving mold base 5 with the molding material is moved to the top of the ejector cylinder 14 and the ejector plate 15. At the same time, the corresponding air inlet pipe 21 and exhaust pipe 22 valves are opened to deliver hot air to the moving mold base 5, so that its temperature returns to the normal level, which is convenient for subsequent demolding. Then the cutting bracket 32 ​​starts working. The telescopic end of the cutting cylinder 33 drives the cutting connecting plate 34, the cutting frame 36 and the cutter 37 to move downward, cutting away the excess scrap at the end of the moving mold base 5. After the cutting is completed; Then the ejector cylinder 14 is activated. The telescopic end of the ejector cylinder 14 drives the ejector plate 15 and the ejector connecting plate 9 to move upward. The ejector connecting plate 9 drives the forming pressure block 7 to move upward through the lifting guide rod 8, ejecting the finished shoe sole in the forming groove 6. The cutting frame 36 and the limiting push plate 40 continue to move, pushing the ejected shoe sole to the outside of the main frame 2. At the same time, the moving mold base 5 and the forming pressure block 7 are cleaned by the cleaning cloth 42. After the ejection is completed, the ejection cylinder 14 is reset, and the first spring 10 drives the forming pressure block 7, the lifting guide rod 8 and the ejection connecting plate 9 to fall back to reset. This completes one full operation cycle, and the equipment can then cycle through the next round of feeding, extrusion, cooling, station switching, heating, demolding, cutting, and cleaning operations.
