[0027] Reference Figure 1-3 , an automobile seal with high sealing performance, comprising a sealing ring 1, an annular notch 2 is provided on the outer side of the sealing ring 1, an annular elastic rubber sheet 3 is installed on the sealing ring 1 through the annular notch 2, and an injection port 4 connected to the annular notch 2 is provided on the sealing ring 1. According to the above technical scheme, specifically, the sealing ring 1 is inserted into the groove on the inner side of the engine cylinder head to ensure that the surface of the sealing ring 1 is evenly fitted with the groove, and then the injection nozzle of the glue injection machine is squeezed to fit the injection port 4, and then the glue injection machine is started to allow a large amount of rubber liquid to be injected into the annular notch 2 through the injection port 4. As the rubber liquid in the annular notch 2 increases, the rubber liquid squeezes the annular elastic rubber sheet 3, and then the annular elastic rubber sheet 3 is deformed and squeezes the inner wall of the groove on the inner side of the engine cylinder head, thereby increasing the friction between the sealing ring 1 and the groove on the inner side of the engine cylinder head, thereby making the sealing ring 1 placed more stably and ensuring the high sealing performance of the seal as much as possible.
[0028] Among them, it should be additionally explained that the glue injection machine can use the Guanjiao small single-component RTM injection machine produced by Dongguan Guanjiao Machinery Co., Ltd.
[0029] Reference Figure 2 The annular elastic rubber sheet 3 is specifically fluororubber, which is a polymer elastomer with special properties.

[0030] Reference Figure 3 The sealing ring 1 is installed with a soft rubber ring 5 through the injection port 4, and the soft rubber ring 5 is used to seal the gap between the injection port 4 and the injection nozzle of the glue injection machine;
[0031] It should be noted that during operation, the front end of the nozzle needs to be squeezed onto the soft rubber ring 5 rather than inserted into the injection port 4. This helps to avoid the inconvenience of pulling the nozzle out of the injection port 4 after the rubber liquid in the annular groove 2 solidifies.
[0032] Reference Figure 1 and Figure 4 A pressing structure 6 is provided on one side of the sealing ring 1, and the pressing structure 6 includes a mounting ring 601 and a placing ring 603 located on one side of the mounting ring 601. A placing groove 604 is provided on one side of the placing ring 603. The sealing ring 1 is adapted to the placing groove 604. The placing groove 604 is convenient for placing the sealing ring 1. A plurality of push rods 602 are installed on one side of the mounting ring 601. The placing ring 603 is installed on the plurality of push rods 602. A grip 605 is installed on the mounting ring 601. According to the above technical solution, specifically Specifically, the sealing ring 1 is placed in the placement groove 604, and then the handle 605 is held by hand, and the sealing ring is inserted into the groove on the inner side of the engine cylinder head by using the extrusion structure 6. At this time, the handle 605 is pushed so that the mounting ring 601 is used to extrude the sealing ring 1, so that the sealing ring 1 is evenly fitted in the groove on the inner side of the engine cylinder head, and the sealing performance of the sealing ring 1 is affected as much as possible due to the sealing ring 1 not being able to evenly fit in the groove on the inner side of the engine cylinder head during installation. After that, the extrusion structure 6 can be directly removed.
[0033] Working principle:
[0034] The automobile seal with high sealing performance is prepared by inserting a sealing ring 1 into the groove on the inner side of an engine cylinder head to ensure that the surface of the sealing ring 1 is evenly fitted with the groove, and then squeezing and fitting the injection nozzle of a glue injection machine to an injection port 4, and then starting the glue injection machine to allow a large amount of rubber liquid to be injected into the annular groove 2 through the injection port 4. As the amount of rubber liquid in the annular groove 2 increases, the rubber liquid squeezes the annular elastic rubber sheet 3, and then the annular elastic rubber sheet 3 is deformed and squeezes the inner wall of the groove on the inner side of the engine cylinder head, thereby increasing the friction between the sealing ring 1 and the groove on the inner side of the engine cylinder head, thereby making the sealing ring 1 more stably placed and ensuring the high sealing performance of the seal as much as possible.
[0035] The automobile seal with high sealing performance is prepared by placing the sealing ring 1 in the placement groove 604, then holding the handle 605, and then using the extrusion structure 6 to insert the sealing ring into the groove on the inner side of the engine cylinder head. At this time, the handle 605 is pushed to make the mounting ring 601 be used to squeeze the sealing ring 1, so that the sealing ring 1 is evenly fitted in the groove on the inner side of the engine cylinder head, and the sealing performance of the sealing ring 1 is avoided as much as possible due to the sealing ring 1 not being able to evenly fit in the groove on the inner side of the engine cylinder head during installation.
