[0010] As can be seen from the above, the setting of the positioning hole enables the positioning hole to be matched and connected with the relevant structure on the product where the sealing ring is installed to achieve the positioning of the guide mold, which is more conducive to accurately installing the sealing ring into the sealing ring installation groove of the product.

[0011] A further solution is that the sealing ring installation auxiliary tooling also includes a fixing seat, and the fixing seat has a positioning groove or a positioning column.

[0012] As can be seen from the above, by adding a fixing seat, the product can be fixed during the installation of the sealing ring, so as to be more conducive to installing the sealing ring into the sealing ring installation groove of the product.

[0013] A further solution is that when the fixing seat has a positioning slot, the bottom surface of the positioning slot is inclined in the height direction; when the fixing seat has a positioning column, a support platform is formed at the bottom of the positioning column, the top surface of the support platform is inclined in the height direction, and the positioning column is perpendicular to or inclined to the top surface of the support platform.

[0014] As can be seen from the above, this design allows the fixing seat to make the depth direction of the sealing ring installation groove of the product parallel to the height direction of the fixing seat during the installation of the sealing ring when the top surface of the product is inclined, thereby making it easier for the pressing mold to press the sealing ring into the sealing ring installation groove of the product.

[0015] A further solution is that the guide mold, the pressing mold and the fixing seat are all formed by injection molding.

[0016] As can be seen from the above, the guide mold, the pressing mold and the fixing seat formed by the injection molding process all have the advantages of being light in weight and having a strength that can meet the use requirements.

[0039] Preferably, the guide mold 1 also has a cavity 131, and the cavity 131 is recessed from one end of the platform portion 13 away from the column portion 12 into the platform portion 13; of course, as another optional solution, the cavity 131 can also penetrate the guide mold 1 in the height direction of the guide mold 1. This design can reduce the weight of the guide mold 1 and save the production cost of the guide mold 1 while ensuring the strength of the guide mold 1. In addition, the guide mold 1 is preferably formed by injection molding, so that the guide mold 1 can have sufficient strength, and can also reduce the weight of the guide mold 1, and make the molding of the guide mold 1 more convenient. Furthermore, the guide mold 1 is preferably provided with a positioning hole 110, which extends in the height direction from the locking portion 11 away from the end of the column portion 12 into the guide mold 1. By providing the positioning hole 110, when the guide mold 1 is installed on the product 31, the positioning hole 110 can be matched and connected with the relevant structure on the product 31 to realize the positioning of the guide mold 1, which is more conducive to the accurate installation of the sealing ring 32 into the sealing ring installation groove 312 of the product 31.

The pressing mold 2 is preferably formed by injection molding, so as to ensure that the pressing mold 2 has sufficient strength, and the weight of the pressing mold 2 is relatively light, and the molding of the guide mold 1 is more convenient.

[0041] When installing the sealing ring 32, first place the guide mold 1 on the product 31 so that the locking portion 11 is locked and connected with the product 31 (such as the inner ring wall 3121 of the sealing ring installation groove 312 in the present embodiment), and the bottom of the column portion 12 is adjacent to the top of the sealing ring installation groove 312; then, the sealing ring 32 is sleeved on the table portion 13 of the guide mold 1, and the sealing ring 32 is moved to the column portion 12 of the guide film 1, so that the sealing ring 32 is expanded; finally, the pressing mold 2 is sleeved on the guide mold 1, and the pressing frame portion 22 of the pressing mold 2 is slidably adjacent to the column portion 12 of the guide mold 1, and then the pressing mold 2 is pushed toward the product 31, so that the pressing frame portion 22 presses the sealing ring 32 into the sealing ring installation groove 312 of the product 31.

[0042] In addition, as in the present embodiment, the outer contour of the engaging portion 11, the outer contour of the column portion 12, and the outer contour of the pressing frame portion 22 are all cylindrical, and the outer contour of the platform portion 13 and the outer contour of the operating frame portion 21 are all truncated cone-shaped. Of course, as another optional scheme, in other embodiments, the outer contour of the engaging portion 11, the outer contour of the column portion 12, and the outer contour of the pressing frame portion 22 are all prism-shaped, and the outer contour of the platform portion 13 and the outer contour of the operating frame portion 21 are all prism-shaped. Among them, the pressing frame portion 22 is located on the bottom of the large cross-section of the operating frame portion 21. It can be seen that the shape of the guide mold 1 and the pressing mold 2 can be adjusted according to the sealing ring installation groove 312 of the product 31, so that the sealing ring installation auxiliary tooling 100 can be applied to products 31 of different shapes.

[0043] In summary, it can be seen that the design of the sealing ring installation auxiliary tooling 100 can effectively reduce the difficulty of installing the sealing ring 32, improve the installation efficiency of the sealing ring 32, and ensure that the sealing ring 32 can be accurately installed in place.
