[0002] Vulcanization is the process of forming a network of linear polymers through cross-linking. It is named because the original natural rubber products were cross-linked with sulfur as a cross-linking agent. In terms of physical properties, vulcanization is the process of converting plastic rubber into elastic rubber or hard rubber. For example, a vulcanization mold for producing porous rubber parts is currently disclosed. The application number is CN202510288747.X, and the patent name is "A Rubber Injection Molding Machine for Soft Cushion Assemblies". This patent can remove sticky rubber scraps remaining on the parting surface of the lower mold in a relatively gentle manner, thereby avoiding scratches on the parting surface of the mold and causing damage.

[0027] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0028] 1. A mixed heating and precise temperature control mechanism is set up. Through the cooperation of the interlayer heat exchange cylinder, the embedded heating ring frame and the electric heating element, the inner side of the rubber compound is heated, and the heat transfer oil passing through the interlayer heat exchange cylinder is also heated and heated, thereby increasing the temperature of the heat transfer oil. Then, through the cooperation of the circulating heating chamber, the heating oil injection port, the hot oil delivery pipe, the cold oil delivery elbow, the uniform diversion pipe, the piezoelectric ceramic micro pump, the heat preservation oil storage tank and the circulating return pipe, the heat transfer oil is conveniently circulated and transported, and the heat transfer oil can be evenly surrounded by the outside of each vulcanization molding tank, circulating and uniformly heating the outside of the rubber compound, realizing synchronous heating of the inside and outside, and improving the vulcanization effect.

[0029] In addition, external and internal cavity temperature sensors are integrated to detect and analyze the heating temperature inside and outside the vulcanization molding tank in real time, dynamically adjust the power of the electric heating element and the flow rate of the piezoelectric ceramic micropump, reduce the temperature difference between the inside and outside of the vulcanization molding tank, improve the level of intelligence, and realize independent control of the temperature of each cavity of the multi-cavity mold, improve accuracy, facilitate the vulcanization of rubber rings of different materials, and ensure stability;

[0030] Through the cooperation of the three-way electromagnetic regulating valve, flow direction regulating pipe, fin radiator and high-efficiency micro fan, the flow direction of the heat transfer oil can be adjusted, and the regulation of heat and cold exchange is realized, which facilitates the gradual gradient cooling of the rubber material inside the vulcanization molding tank, prevents excessive cooling at one time, and avoids internal stress and deformation of rubber products due to sudden temperature changes.

[0031] 2. A rapid cooling and automated demoulding mechanism is provided. The circulating cooling cavity and the U-shaped water supply pipe cooperate to facilitate cooling of the rubber ring inside the vulcanization molding tank. At the same time, the overflow cooling pipe is spliced ​​to allow the cooling water inside the circulating cooling cavity of the multi-cavity vulcanization upper mold to pass through the overflow cooling pipe and enter the circulating cooling cavity of the multi-cavity vulcanization lower mold, facilitating the flow of cooling water between the multi-cavity vulcanization lower mold and the multi-cavity vulcanization upper mold, further enhancing the cooling effect.

[0032] The cooling water after heat exchange is utilized through the coordination of the uniform diversion box, the waste heat conversion tube and the waste heat recovery tube, so that the waste heat carried by the cooling water after heat exchange is used to preheat the heat transfer oil, so that the heat transfer oil is kept at a certain temperature. In the subsequent heating, the temperature rise rate of the heat transfer oil is increased, the power consumption of the electric heating element is reduced, and resources are saved.

[0033] Through the cooperation of the reset demoulding spring, the lifting reset rod, the lifting splicing plate and the concave positioning shaft seat, the rapid demoulding top plate is pushed up, and the molded rubber is pushed up by the edge material, thereby realizing automatic demoulding. Then, through the cooperation of the two-way synchronous hydraulic push rod and the horizontal moving slide frame, the rapid demoulding top plate with the molded rubber product is pushed to the bottom of the multi-hole pressing and cutting frame, and the edge material circular cutting knife is used to cut off the edge material, thereby realizing the separation of the molded rubber product and the waste material, facilitating the centralized recycling of the waste material and reducing the waste of resources.

[0034] In summary, by coordinating the mixed heating with the precise temperature control mechanism and the rapid cooling with the automatic demoulding mechanism, the synchronization and uniformity of the internal and external heating in the initial stage of vulcanization and the insulation stage are guaranteed, and large temperature differences are not likely to occur, thereby ensuring the vulcanization effect. At the same time, the vulcanization temperature inside each cavity of the multi-cavity mold is monitored in real time and adjusted separately, thereby realizing the independence of each cavity, facilitating the production of rubber of different materials, and improving adaptability. During cooling, cooling can be carried out in stages to prevent internal stress and deformation of rubber products due to sudden temperature changes. After cooling and molding, demoulding and waste removal can be automatically performed, reducing worker operations and increasing vulcanization efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

The heat is transferred through the heat-conducting support inner cylinder 423 to heat the inner side of the preformed rubber between the vulcanization molding groove 402 and the vulcanization splicing upper groove 427.

[0068] At the same time, the piezoelectric ceramic micro pump 409 is started to pump the heat transfer oil inside the heat preservation oil storage tank 410 into the uniform diversion pipe 408, and then the heat transfer oil is sent into the interlayer inside the interlayer heat exchange tube 406 through the cold oil delivery elbow 407, so as to facilitate the electric heating element 425 on the embedded heating ring frame 424 to heat the heat transfer oil inside the interlayer heat exchange tube 406, thereby increasing the temperature of the heat transfer oil. The heat transfer oil is then sent into the heating oil injection port 404 through the hot oil delivery pipe 405, and then flows into the circulating heating chamber 403, so that the heat transfer oil can flow around the outside of the vulcanization molding tank 402 along the circulating heating chamber 403, and heat the outside of the preformed rubber material inside the vulcanization molding tank 402, thereby achieving heating inside and outside at the same time, improving the uniformity of heating of the rubber material, and ensuring the vulcanization effect;

[0069] Next, the heated thermal oil enters the oil drain connection chamber 413 through the oil drain hole 414, and is then transported back to the heat-insulating oil storage tank 410 through the circulation return pipe 411. Simultaneously, during the reflux process, the self-operated pressure valve 412 cooperates to allow the thermal oil to completely fill the circulation heating chamber 403, the oil drain connection chamber 413, and the oil drain hole 414. The thermal oil can only be discharged after the pressure increases, thus preventing gaps and ensuring uniform heating of the thermal oil.

[0070] The heat transfer oil that is returned to the heat preservation oil storage tank 410 carries residual heat. It is then fed back into the interlayer heat exchange cylinder 406 by the piezoelectric ceramic micro pump 409 and the uniform diverter pipe 408, where it is heated before being transported to the circulating heating chamber 403. This achieves cyclic heating, and as the heat transfer oil with residual heat circulates, the efficiency of subsequent heating is improved.

[0071] In addition, the external cavity temperature sensor 415 and the internal cavity temperature sensor 422 cooperate to monitor and control the heating temperature of the outer and inner sides of each vulcanization molding tank 402, realizing independent control of the temperature of each cavity of the multi-cavity mold, improving accuracy and facilitating the vulcanization of rubber rings of different materials;

[0072] When vulcanization is completed and cooling is required, the electric heating element 425 is turned off through the inner cavity temperature sensor 422, and the three-way electromagnetic regulating valve 418 on the hot oil delivery pipe 405 corresponding to the position of the vulcanization molding tank 402 is controlled to open through the outer cavity temperature sensor 415, so that the heat-conducting oil enters the fin radiator 416. At the same time, the high-efficiency micro-blower 421 is started to allow air to enter the heat dissipation dustproof shell 419. After heat exchange and cooling of the heat-conducting oil inside the fin radiator 416, the air is then sent to the hot oil delivery pipe 405 through the flow direction regulating pipe 417, and re-injected into the heating oil injection port 404 and the circulation heating chamber 403, so as to circulate and cool the rubber material inside the vulcanization molding tank 402, thereby realizing initial gradual gradient cooling.

[0073] Then, after the initial heat exchange is completed, the circulation of the heat transfer oil is stopped, and the cooling water is sent into the circulating cooling cavity 501 on the multi-cavity vulcanization lower mold 401 and the multi-cavity vulcanization upper mold 426 through the cooperation of the connecting guide pipe 504 and the U-shaped water supply pipe 503, so as to quickly cool the vulcanized rubber material. At the same time, when the multi-cavity vulcanization lower mold 401 and the multi-cavity vulcanization upper mold 426 are molded together, the bottom end of the overflow cooling pipe 502 inside the multi-cavity vulcanization lower mold 401 is embedded in the overflow cooling pipe 502 inside the multi-cavity vulcanization upper mold 426, and the valve inside the U-shaped water supply pipe 503 on the multi-cavity vulcanization upper mold 426 is closed, so that the cooling water accumulates inside the circulating cooling cavity 501, and then passes through the overflow cooling pipe 502 into the circulating cooling cavity 501 on the multi-cavity vulcanization lower mold 401, so that the cooling water flows between the multi-cavity vulcanization lower mold 401 and the multi-cavity vulcanization upper mold 426, further enhancing the cooling effect.

[0074] The cooling water after heat exchange is discharged through the U-shaped water supply pipe 503 and the connecting guide pipe 504 on the other side of the multi-cavity vulcanization lower mold 401, and is sent to the interior of the uniform diversion box 505 through the waste heat recovery pipe 507. After uniform diversion, it is then transported to the interior of the waste heat conversion pipe 506, thereby preheating the heat transfer oil in the heat preservation oil storage tank 410, improving the utilization rate of the waste heat, ensuring the temperature of the heat transfer oil, and increasing the heating rate of the heat transfer oil during subsequent vulcanization, thereby improving efficiency;

[0075] Then, after cooling is completed, the hydraulic pressure rod 518 is started to lift the downward push plate 519 and pull the multi-cavity vulcanization upper mold 426 to slide and rise along the lifting anti-deflection rod 2 to release the mold. At the same time, the elastic characteristics of the reset demoulding spring 513 are used to lift the lifting reset rod 512, the lifting splicing plate 514, the concave positioning shaft seat 515 and the quick demoulding top plate 516. In addition, because the rubber material is vulcanized, the scraps will flow into the scrap overflow groove 517, which makes it easier for the quick demoulding top plate 516 to push the molded rubber up through the scraps, thus realizing automatic demoulding.

[0076] Subsequently, the bidirectional synchronous hydraulic push rod 510 is activated to push the N-shaped traction bracket 511, the lifting and resetting rod 512, and the lifting splicing plate 514 to slide along the horizontal movable slide frame 509, forcing the quick demoulding top plate 516 to move out from between the multi-cavity vulcanization lower mold 401 and the multi-cavity vulcanization upper mold 426, so that the quick demoulding top plate 516 corresponds to the installation position of the multi-hole pressing and cutting frame 520. Then, the hydraulic pressure rod 518 pushes the downward pushing plate 519, the multi-hole pressing and cutting frame 520, and the edge material ring cutter 521 downward to cut the edge material on the quick demoulding top plate 516;

[0077] Finally, after the edge material of the molded rubber is cut off, it loses its limit and is pushed down by the elastic rubber top block 522 and falls on the vulcanization preparation machine base 1. In addition, due to the cooperation of the concave positioning shaft seat 515, after the edge material is cut off, when the mold is reopened, the quick demoulding top plate 516 can be rotated to facilitate the cleaning of the edge material to one side for centralized recycling, reducing the waste of waste and improving the utilization rate. After the waste material is cleaned up, it is moved back to between the multi-cavity vulcanization lower mold 401 and the multi-cavity vulcanization upper mold 426 with the cooperation of the two-way synchronous hydraulic push rod 510, which is convenient for subsequent demoulding and reuse.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features.
