Description

Technical Field

[0001] The utility model relates to the technical field of valve oil seal production, in particular to a valve oil seal production device. Background Art

[0002] Valve oil seal is a type of oil seal, which is generally made of an exoskeleton and fluororubber that are vulcanized together. During its production process, a special valve oil seal production device is used to ensure the molding of the valve oil seal.

[0003] Existing valve oil seal production equipment generally consists of an upper mold (pressing plate), a middle mold (storage bin and upper cavity), a lower mold (lower cavity and demolding mechanism), and a thermoforming device. During the production process, the valve oil seal skeleton is first placed into the lower mold cavity. After the middle and lower molds are closed, the raw rubber strips are discharged into the middle mold storage bin. The upper mold pressing plate is then installed on top of the middle mold. The combined upper and lower molds are then placed on the loading platform of the thermoforming device. The thermoforming device then heats and compresses the rubber strips inside the upper and middle molds, forcing the rubber material into the lower mold cavity. After the metal skeleton is vulcanized and formed, the loading platform is pushed out by an electric telescopic rod provided in the thermoforming device. Because it is necessary to ensure that the internal holes of the lower mold are fully formed, the rubber strips must be spread throughout the middle mold before the vulcanization process. However, after the molding process is completed, the rubber material inside the middle mold storage bin cannot be fully utilized. Moreover, the excess rubber, having been vulcanized into a flat gasket shape, cannot be recycled, resulting in a waste of raw materials. Furthermore, a scraper is required to scrape away excess waste material from the mold storage bin, resulting in low working efficiency. Therefore, in view of the drawbacks of the prior art, it is urgent to improve the valve oil seal production device to solve the above problems. Utility Model Content

[0026] Furthermore, a cavity is provided between the heat-insulating outer frame 412 and the material storage barrel 413 , and the heating tube 416 is arranged inside the cavity to facilitate heat transfer and improve the heat-insulating effect.

[0027] Furthermore, the raw material supply mechanism 4 also includes a discharging component 42 for adjusting the raw material discharge amount inside the storage barrel 413 according to different production needs. A mounting plate 421 is provided in the discharging component 42, and the mounting plate 421 is fixedly installed on the bottom of the storage barrel 413. A connecting frame 422 is fixedly installed on the bottom of the mounting plate 421.

[0029] Example 2: Please refer to Figure 7 , and combined with Example 1, it is further obtained that the auxiliary blanking component 5 includes a mounting frame 501, the mounting frame 501 is fixedly installed inside the lower mold base 1, a motor base 502 is fixedly installed at the bottom of the mounting frame 501, a second motor 503 is fixedly installed inside the motor base 502, a screw 504 is fixedly installed on the output shaft of the second motor 503, a guide rod 505 is fixedly installed inside the mounting frame 501, a second movable plate 506 is slidably installed outside the guide rod 505, a ejection column 507 is fixedly installed on the top of the second movable plate 506, and a position sensor 508 is provided on the top of the mounting frame 501, which is convenient for ejecting the valve oil seal inside the center mold 35 after the valve oil seal is formed, thereby accelerating the blanking rate.

[0030] Furthermore, the second movable plate 506 is threadedly mounted on the screw rod 504 , and connecting grooves are provided at corresponding positions of the mounting frame 501 and the ejecting column 507 to facilitate ejection and unloading operations.

[0031] During actual operation, when valve oil seals need to be produced, molten rubber raw materials can first be added to the interior of the storage barrel 413 through the feed pipe 414. Then, to prevent the raw materials inside the storage barrel 413 from solidifying as production progresses, the temperature controller 415 can be operated to increase the temperature of the heating pipe 416 to generate heat, thereby keeping the raw materials inside the storage barrel 413 warm. To further improve the insulation effect, the drive motor 417 can be turned on to rotate the stirring blade 418 to stir the raw materials inside the storage barrel 413, ensuring that the raw materials inside the storage barrel 413 are kept warm. Subsequently, the second motor 503 can be operated to rotate the screw 504. Under the action of the guide rod 505, the second movable plate 506 can be lowered. Under the detection of the position sensor 508, the top of the ejector column 507 is ensured to be parallel to the installation frame 501. Then, the electric cylinder 33 is operated, and under the action of the installation rod 31, the first movable plate 34 can be lowered, thereby lowering the upper mold and the middle mold 35. The middle mold 35 will be aligned with the top of the installation frame 501, and the upper mold will be aligned with the middle mold 35. After the alignment is completed, according to the amount of rubber required for injection molding, the first motor 423 can be turned on to rotate the first gear 424, thereby rotating the meshing connecting gear plate 425, rotating the arc-shaped connecting rod 429, and adjusting the opening and closing angle of the adjusting plate 428 to adjust the opening and closing degree, thereby controlling the amount of raw material flowing out of the telescopic discharge tube 4210. After adjustment is completed, the material will flow from the interior of the storage barrel 413 into the interior of the upper mold and the middle mold 35 through the action of the telescopic discharge tube 4210 for injection molding. When the discharge volume reaches the required amount, the flow sensor outside the telescopic discharge tube 4210 transmits a signal to the first motor 423, causing the first motor 423 to rotate in the opposite direction, causing the adjustment plate 428 to rotate in the opposite direction, achieving closure, and then completing the valve oil seal molding operation. After molding is completed, the electric cylinder 33 can be operated to raise the first movable plate 34 to separate the upper mold from the middle mold 35. Then, to increase the discharge speed, the second motor 503 can be turned on to rotate the screw 504. Under the action of the guide rod 505, the second movable plate 506 can be moved to move the ejector pin 507 upward. Under the ejection action of the ejector pin 507, the valve oil seal formed in the middle mold 35 can be ejected for unloading, avoiding the tedious steps of ejecting one by one.

[0032] The above embodiments merely represent one or several implementations of the present invention.

It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
