[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Reference Figures 1 to 11A demolding device for rubber products includes a hot press vulcanizing machine 1 and an extension frame 3. The extension frame 3 is fixed to one side of the hot press vulcanizing machine 1. A translation component is provided on the upper side of the extension frame 3. The translation component includes a moving frame 14, a hydraulic cylinder 15, and two guide rails 17. The hot press vulcanizing machine 1 includes a table 2. The hydraulic cylinder 15 is fixed on the upper side of the table 2. The hydraulic cylinder 15 is externally connected to a solenoid valve through an oil pipe. During use, when it is necessary to demold the rubber product, the hot press vulcanizing machine 1 needs to be opened first. After the hot press vulcanizing machine 1 is opened (the state is as follows), Figure 10 As shown), by controlling the retraction of the hydraulic cylinder 15, the moving frame 14 automatically approaches the hot press vulcanizing machine 1. The shaft end of the hydraulic cylinder 15 is fixedly provided with a driving plate 16. Several support legs 18 are fixedly provided on the lower side of the moving frame 14. The guide rail 17 is fixed on the upper side of the table 2 and the extension frame 3. The moving frame 14 has a U-shaped structure. Two movable legs 19 are slidably provided on the outer periphery of the moving frame 14. The movable legs 19 are fixed on one side of the driving plate 16. The movable legs 19 and the support legs 18 slide on the inner side of the guide rail 17. An elastic connection assembly is provided between the movable legs 19 and the moving frame 14. The elastic connection assembly includes a fixed plate 23. The fixed plate 23 is fixed at one end of the moving frame 14. A strong tension spring 24 is fixed between the fixed plate 23 and the movable legs 19. The tension of the strong tension spring 24 is much greater than the tension of the holding spring 22. Two spacer plates 25 are fixedly provided on the side of the fixed plate 23 near the strong tension spring 24. The spacer plates 25 can contact the movable legs 19.

[0039] like Figure 3 , Figure 4As shown, the upper side of the extension frame 3 is equipped with a suction assembly for suctioning rubber products, and a translation assembly for driving the suction assembly to translate. The suction assembly includes a movable plate 4, and a vent box 5 is fixedly installed on the lower side of the movable plate 4. Several telescopic contact assemblies are provided on the lower side of the vent box 5. Each telescopic contact assembly includes a fixed tube 10. A through hole is provided on the lower side of the vent box 5, and the fixed tube 10 is fixed inside the through hole. A movable tube 11 is slidably installed inside the fixed tube 10. A contact spring 12 is fixed between the upper side of the movable tube 11 and the lower side of the movable plate 4. Several limiting blocks are fixedly provided on the outer periphery of the moving tube 11, and several limiting grooves are provided on the inner wall of the fixed tube 10. The limiting blocks slide inside the limiting grooves. A suction cup 13 is fixedly provided on the outer periphery of the moving tube 11, and an airtight ring is fixedly provided at the lower end of the fixed tube 10. The moving tube 11 slides inside the airtight ring. During the demolding and removal of the rubber product, the hydraulic cylinder 15 needs to be retracted by controlling it. When the hydraulic cylinder 15 retracts, it will drive the moving frame 14 and the vent box 5 to approach the hot press vulcanizing machine 1, causing the vent box 5 to move above the rubber product. After the rubber product is placed above, the vent box 5 needs to descend so that the suction cup 13 can contact the rubber product. A through hole is provided on one side of the vent box 5, and a flexible tube 6 is fixedly installed inside the through hole. A material drop hole is provided on the upper side of the extension frame 3, and the flexible tube 6 is located inside the material drop hole. A material receiving box 44 is provided on one side of the hot press vulcanizing machine 1, located below the material drop hole. Two guide buckles 7 are fixedly installed on the two opposite sides of the movable plate 4. A guide block 8 is slidably installed inside the guide buckle 7. The guide block 8 has an L-shaped structure and slides within the moving frame 14. Specifically, on both sides of the movable frame 14, T-slots are provided on corresponding sides. A T-block is fixed on the side of the guide blocks 8 that is far apart from each other. The T-block slides inside the T-slot. A round hole is provided on one side of each of the two guide blocks 8. A round rod 20 is slidably provided inside the round hole. A connecting seat 21 is fixed at one end of the round rod 20. The connecting seat 21 is fixed on the inner wall of the movable frame 14. A retaining spring 22 is fixed on one side of the connecting seat 21. The retaining spring 22 will cause the guide block 8 and the T-block on one side to be at one end of the T-slot when they are not under normal force (as shown in the state). Figure 10 As shown), one end of the retaining spring 22 is fixed on one side of the guide block 8, and the connecting seat 21 is located between the guide block 8 and the movable leg 19.

[0040] like Figure 7 , Figure 8As shown, a lifting assembly is provided between the translation assembly and the suction assembly. The lifting assembly is used to drive the suction assembly to rise and fall, and the translation assembly is used to drive the lifting assembly. The lifting assembly includes two inclined drive frames 26, which are fixed to the lower side of the movable frame 14. An inclined drive groove 27 is provided on the side of the two inclined drive frames 26 that are close to each other. Drive columns 28 are fixed on the two sides of the movable plate 4 that are far apart. The drive columns 28 slide on the inner side of the inclined drive groove 27 and match the inclined drive groove 27. The cross-section of the drive columns 28 is circular. A guide sleeve 29 is fixed on the upper side of the platform 2, and a guide plate 9 is fixed on the lower side of the movable plate 4. The guide plate 9 can be inserted into and detached from the inner side of the guide sleeve 29 and matches the guide sleeve 29. A hollow seat 30 is fixed on one side of the guide sleeve 29. A blocking wheel 31 is rotatably provided on the inner side of the hollow seat 30. The blocking wheel 31 can contact the guide plate 9. During the demolding and removal of the product, when the vent box 5 reaches above the rubber product, the guide plate 9 will contact the blocking wheel 31. At this time, the guide plate 9 will be blocked by the blocking wheel 31, and then the hydraulic cylinder 15 will continue to retract. At this time, the movable plate 4, vent box 5, guide plate 9, and suction cup 13 will not move, while the moving frame 14 will continue to move. When the moving frame 14 moves, it will drive the inclined drive frame 26 to move together. When the inclined drive frame 26 moves, it will cause the drive column 28 to descend through the inclined drive groove 27. The drive column 28 will drive the movable plate 4, vent box 5, guide plate 9, and suction cup 13 to descend together. At the same time, the holding spring 22 will be compressed. Then the guide plate 9 will be inserted into the guide sleeve 29, and the suction cup 13 will also descend to contact the rubber product. When the descent is completed, the support leg 18 on one side will move to one end of the guide rail 17 and will be blocked. At this time, the support leg 18 and the moving frame 14 cannot continue to move (state as shown). Figure 1 As shown in the figure, the state of the tension spring 24 remains unchanged at this time. The tension spring 24 is in an unstretched state, which enables automatic descent. Moreover, it can achieve translation and lifting through a single hydraulic cylinder 15, and has the function of one-drive-multiple-action.

[0041] like Figure 3 , Figure 5 , Figure 11As shown, a negative pressure component is provided on the upper side of the extension frame 3. The negative pressure component is located on one side of the translation component. The negative pressure component is used to generate negative pressure and drive the suction component to perform suction. When the negative pressure component generates negative pressure, it can cause the suction component to generate suction force, thereby sucking up the rubber product. The translation component is used to drive the negative pressure component to generate negative pressure. The negative pressure component is connected to the suction component and is used to trigger the negative pressure component to automatically reset. When the negative pressure component resets, it can eliminate the negative pressure. When the negative pressure component eliminates the negative pressure, it can prevent the suction component from sucking up the rubber product. The negative pressure component includes a pressure transformer 32, which is fixed on the upper side of the extension frame 3. A sealing ring 33 is slidably provided on the inner side of the pressure transformer 32. A piston 34 is fixedly provided on the inner side of the sealing ring 33. A connection hole is provided on one side of the pressure transformer 32. A flexible tube 6 is fixed on the inner side of the connection hole. A pull-out frame 35 and a limiting seat 36 are fixedly provided on one side of the piston 34. The pull-out frame 35 has an L-shaped structure, and the limiting seat 36 has a J-shaped structure. A sliding part is provided on the outer periphery of the pull-out frame 35. A connecting plate 37 is fixed inside the transformer tank 32. A return spring 38 is fixed between the connecting plate 37 and the piston 34. A beveled latch 39 is slidably mounted on the inner side of the limiting seat 36. A locking spring 40 is fixed between one side of the beveled latch 39 and the inner side of the limiting seat 36. One end of the limiting seat 36 can contact the beveled latch 39. A double beveled locking hole 41 is provided on one side of the connecting plate 37. The double beveled locking hole 41 matches the beveled latch 39, and the beveled latch 39 can... The plug-in disassembly mechanism is located inside the double-beveled locking hole 41. One bevel of the double-beveled locking hole 41 is shorter, and the other bevel is longer. A pulling frame 42 and a beveled unlocking head 43 are fixedly provided on one side of the driving plate 16. The pulling frame 42 matches the pulled frame 35 and can contact the pulled frame 35. During the demolding and removal of the rubber product, after the movable plate 4, the vent box 5, the guide plate 9, and the suction cup 13 have descended and the suction cup 13 has contacted the rubber product (in the state as follows). Figure 1As shown), at this time, the pulling frame 42 will come into contact with the pulled frame 35, and then the suction cup 13 needs to generate suction to hold the rubber product. When the suction cup 13 needs to generate suction, the hydraulic cylinder 15 needs to be controlled to continue to retract, which will cause the driving plate 16, the movable leg 19, the pulling frame 42, the pulled frame 35, and the piston 34 to automatically approach the hot press vulcanizing machine 1, while the support leg 18 and the moving frame 14 will not move. At this time, a negative pressure will be generated inside the transformer tank 32. Due to the transformer tank 32, the flexible tube 6, the vent box 5, and the fixed tube 10 The movable tube 11 and the suction cup 13 are connected, so a negative pressure is generated inside the suction cup 13, causing it to suck up the rubber product. Simultaneously, the tension spring 24 is stretched, and the hydraulic cylinder 15 continues to retract, increasing the negative pressure inside the suction cup 13. When the negative pressure reaches a certain value, the movable tube 11, suction cup 13, and rubber product move upwards. At this point, the contact spring 12 is compressed, allowing the rubber product to automatically demold. Then, the beveled locking buckle 39 is pressed into the double beveled locking hole 41 (as shown in the image). Figure 11 As shown), at this time, the hydraulic cylinder 15 will also retract completely, and the inclined unlocking head 43 will match the inclined locking buckle 39. The inclined unlocking head 43 can contact the inclined locking buckle 39, and then the hydraulic cylinder 15 can be extended. During the extension of the hydraulic cylinder 15, the strong tension spring 24 will shorten and return to its original position. Then, after the movable leg 19 contacts the spacer plate 25, the moving frame 14 begins to move away from the hot press vulcanizing machine 1. At this time, the drive column 28, the guide plate 9, and the rubber product will move upward, and the holding spring 22 will also extend and return to its original position. After the guide plate 9 disengages from the guide sleeve 29 and the holding spring 22 is fully returned to its original position, the drive column 28 will have moved upward completely. Then, the moving frame 14, the vent box 5, and the rubber product will move away from the hot press vulcanizing machine 1 together. At this time, the inclined unlocking head 43 will also move away from the hot press vulcanizing machine 1. The inclined edge locking buckle 39 is brought into contact with the inclined edge unlocking head 43. After contact, the head continues to move, lifting the buckle 39 and allowing it to move upwards and disengage from the double inclined edge locking hole 41. At this point, the hydraulic cylinder 15 extends fully, and the piston 34 automatically resets due to the tension of the return spring 38. This reset eliminates the negative pressure in the transformer tank 32, preventing the suction cup 13 from holding the rubber product. The suction cup 13 releases the rubber product, and the movable tube 11 descends and resets. The rubber product then falls naturally into the receiving box 44, completing automatic demolding and automatic material handling. The equipment then returns to its initial state. Figure 10 In the state shown, the initial state will be maintained. By repeatedly controlling the extension and retraction of the hydraulic cylinder 15, continuous demolding and material removal can be performed.

[0042] In summary, a demolding method for a demolding device used for rubber products includes the following steps:

[0043] S1. When it is necessary to remove and demold the rubber product, the hot press vulcanizing machine 1 must be opened first, and then the suction component is moved to the top of the rubber product by the translation component.

[0044] S2. By coordinating the translation component and the lifting component, the suction component descends and comes into contact with the rubber product;

[0045] S3. By combining the translation component and the negative pressure component, the suction component can hold the rubber product.

[0046] S4. By coordinating the translation component and the lifting component, the suction component and the rubber product rise together;

[0047] S5. The suction component and rubber product are removed by the translation component, so that the rubber product is away from the hot press vulcanizing machine 1;

[0048] S6. The translation component and the negative pressure component work together, specifically: the translation component triggers the negative pressure component to automatically reset, causing the suction component to release the rubber product.
