The output of synthetic rubber has greatly exceeded that of natural rubber, among which the largest output is styrene-butadiene rubber. Rubber products are made from mixed rubber made from rubber raw materials in internal mixers. When mixing rubber, the formula is designed according to the characteristics of the required rubber products, and the required product hardness is determined. The product is made and formed by compression molding in a rubber hot press vulcanizer. After the product is formed, the flash is finally treated to make the surface of the product smooth and burr-free.

[0023] like Figure 3 , Figure 5 , Fig.11As shown, a negative pressure component is provided on the upper side of the extension frame 3, and the negative pressure component is located on one side of the translation component. The negative pressure component is used to generate negative pressure, and the negative pressure component is used to drive the suction component to suck. When the negative pressure component generates negative pressure, the suction component can generate suction, thereby sucking 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. The translation component is used to trigger the negative pressure component to automatically reset. When the negative pressure component is reset, the negative pressure can be eliminated. When the negative pressure component eliminates the negative pressure, the suction component cannot suck the rubber product. The negative pressure component includes a transformer tank 32, and the transformer tank 32 is fixed on the upper side of the extension frame 3. A sealing ring 33 is slidably provided on the inner side of the transformer tank 32, and a piston 34 is fixedly provided on the inner side of the sealing ring 33. A connecting hole is provided on one side of the transformer tank 32, and a flexible tube 6 is fixed on the inner side of the connecting hole. A pulled frame 35 and a limiting seat 36 are fixedly provided on one side of the piston 34. The pulled frame 35 is an L-shaped structure, and the limiting seat 36 is a J-shaped structure. There is a connecting plate 37, which is fixed on the inner side of the transformer tank 32. A return spring 38 is fixed between the connecting plate 37 and the piston 34. A bevel lock buckle 39 is slidably provided on the inner side of the limiting seat 36. A locking tension spring 40 is fixed between one side of the bevel lock buckle 39 and the inner side of the limiting seat 36. One end of the limiting seat 36 can contact the bevel lock buckle 39. A double bevel lock hole 41 is provided on one side of the connecting plate 37. The double bevel lock hole 41 matches the bevel lock buckle 39. The bevel lock buckle 39 can The plug-in and disassembly fits on the inner side of the double-beveled lock hole 41, one bevel of the double-beveled lock hole 41 is shorter, and the other bevel of the double-beveled lock hole 41 is longer. A pulling frame 42 and a beveled unlocking head 43 are fixed on one side of the driving plate 16. The pulling frame 42 matches the pulled frame 35, and the pulling frame 42 can contact the pulled frame 35. During the demolding and removal of the rubber product, when the movable plate 4, the vent box 5, the guide plug plate 9 and the suction cup 13 are lowered, and the suction cup 13 contacts the rubber product (the state is as shown in FIG. 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 is required to generate suction to suck the rubber product. When the suction cup 13 is required to generate suction, the hydraulic cylinder 15 needs to be controlled to continue to retract, and then the driving plate 16, the movable leg 19, the pulling frame 42, the pulled frame 35 and the piston 34 will automatically approach the hot press vulcanizer 1, while the supporting leg 18 and the moving frame 14 will not move. At this time, negative pressure will be generated inside the transformer tank 32. Due to the transformer tank 32, the flexible pipe 6, the ventilation box 5, the fixed pipe 10 , the movable tube 11 and the suction cup 13 are in a connected state, so negative pressure will be generated inside the suction cup 13, so the suction cup 13 will suck the rubber product, and at the same time the strong tension spring 24 will be stretched, and then the hydraulic cylinder 15 will continue to retract, and the negative pressure inside the suction cup 13 will become stronger and stronger. When the negative pressure reaches a certain value, the movable tube 11, the suction cup 13 and the rubber product will move upward. At this time, the contact spring 12 will be compressed, so that the rubber product can be automatically demoulded, and then the bevel lock buckle 39 will also be pressed into the double bevel lock hole 41 (the state is as shown in FIG. Fig.11 As shown), at this time, the hydraulic cylinder 15 will also be fully retracted, the bevel unlocking head 43 matches the bevel lock buckle 39, and the bevel unlocking head 43 can contact the bevel lock buckle 39, and then the hydraulic cylinder 15 can be controlled to extend. During the extension of the hydraulic cylinder 15, the strong tension spring 24 will shorten and reset, and then after the movable leg 19 contacts the fixed distance plate 25, the movable frame 14 begins to move away from the hot press vulcanizer 1. At this time, the driving column 28, the guide plug plate 9 and the rubber product will move up, and the retaining spring 22 will also stretch and reset. After the guide plug plate 9 is separated from the guide sleeve 29 and the retaining spring 22 is fully reset, the driving column 28 is completely moved up, and then the movable frame 14, the vent box 5 and the rubber product will move away from the hot press vulcanizer 1 together, and the bevel unlocking head 43 will also be close to The bevel lock buckle 39 is close to the bevel lock buckle 39, and then the bevel unlocking head 43 will contact the bevel lock buckle 39. After the bevel unlocking head 43 contacts the bevel lock buckle 39 and continues to move, the bevel lock buckle 39 can be lifted up, so that the bevel lock buckle 39 can move up and be unstuck from the double bevel lock hole 41. At this time, the hydraulic cylinder 15 will also be fully extended. At this time, the piston 34 will automatically reset due to the tension of the reset spring 38. After the piston 34 is reset, the negative pressure in the transformer tank 32 will be eliminated, and then the suction cup 13 will not be able to continue to suck the rubber product. The suction cup 13 will release the rubber product, and the movable tube 11 will also descend and reset. The rubber product will naturally fall and fall into the material receiving box 44, thereby completing automatic demoulding and automatic material removal. At this time, the equipment will return to the initial state. Fig.10 The state shown is the initial state, and the hydraulic cylinder 15 is repeatedly controlled to extend and retract, so that continuous demoulding and material taking can be carried out.

[0024] In summary, a demoulding method for a demoulding device for rubber products comprises the following steps: S1.
