DETAILED DESCRIPTION
[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] See also Figure 1-4 , the utility model provides a technical solution:
[0020] A high-strength aluminum-magnesium alloy die-casting, including a left die-casting body 1, a center plug 2 is integrally formed in the middle of the die-casting body 1, and an inner rib 3 is fixedly connected to the outside of the center plug 2, a sealing plug body 4 is fixedly connected to the outside of the inner rib 3, and a sealing gasket 5 is sleeved on the outside of the sealing plug body 4, a gasket side hoop 7 is integrally formed at the edge of the die-casting body 1, an annular groove 6 is provided at the clamping connection between the die-casting body 1 and the gasket side hoop 7, a first hole groove 8 is provided on the surface of the gasket side hoop 7, and an outer rib 9 is integrally formed on the outside of the sealing plug body 4.
[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the center plug 2 and the sealing plug body 4 are coaxially arranged, and a center through hole 15 is opened in the middle of the center plug 2. The height of the center plug 2 is less than the height of the sealing plug body 4. By reserving the center through hole 15 in the middle of the center plug 2, this arrangement will facilitate the oil filling pipe to pass through the entire die casting and extend into the oil tank structure; the outside of the die casting body 1 is provided with a rounded square frame 13 through integral molding, and the four corners of the rounded square frame 13 are respectively provided with square grooves 14. After the reserved opening of the oil tank is blocked by the sealing plug body 4, multiple bolts penetrating the square grooves 14 can be used to tighten the oil filling pipe. The fixing parts simultaneously connect the die-casting body 1 and the outer shell of the fuel tank, so that the installation of the die-casting is stable; the upper and lower ends and the left and right ends of the inner side surface of the die-casting body 1 are respectively provided with third hole grooves 16, and the diagonal lines of the inner side surface of the die-casting body 1 are respectively provided with large circular holes 12 and small circular holes 11, the inner diameter of the large circular hole 12 is larger than the inside of the small circular hole 11, and the large circular holes 12 and the small circular holes 11 are respectively distributed in a circular array structure along the center point of the die-casting body 1. When installing the die-casting, the third hole groove 16 will use itself to align with the protrusion on the fuel tank structure to make the assembly and installation of the die-casting more precise.
[0022] like Figure 1 , Figure 2 and Figure 3As shown, the inner side surface of the sealing gasket 5 is provided with a second hole groove 10 which is engaged with the outer rib 9, and the number of the second hole grooves 10 and the number of the outer ribs 9 are arranged correspondingly. The outer shapes of the sealing gasket 5 and the sealing plug body 4 are respectively arranged in a conical structure. After utilizing the softness of the sealing gasket 5 itself and tightly fitting it on the outside of the sealing plug body 4, multiple outer ribs 9 will fit into the second hole groove 10. At this time, the tight connection between the two will effectively improve the connection stability of the sealing gasket 5 after installation without affecting the normal installation of the sealing plug body 4 at a later time.
[0023] Working process: When assembling the high-strength aluminum-magnesium alloy die-casting to an automobile fuel tank of suitable size, the sealing gasket 5 can be firstly mounted on the outside of the sealing plug body 4, and after the sealing gasket 5 is gradually pushed to the root of the central plug 2 and the gasket side hoop 7 is pushed into the first hole groove 8, the die-casting body 1 and the gasket side hoop 7 are simultaneously connected by bolt fixings to limit the sealing structure formed by the sealing gasket 5 and the gasket side hoop 7, and then the sealing plug with the sealing structure can be assembled under the structural reinforcement of the multiple external ribs 9. The body 4 fits and is inserted into the reserved opening of the fuel tank, so that the entire high-strength aluminum-magnesium alloy die-casting can be assembled with the fuel tank as an auxiliary tank cover structure of the automobile. At this time, the sealing plug body 4 can effectively seal the reserved opening of the fuel tank with a conical sealing structure. At the same time, its overall conical structure is set, so that it can be adapted to fuel tanks of various sizes for assembly and use. Then, after a plurality of bolt fasteners are respectively installed into the small circular hole 11 and the large circular hole 12, and the fuel tank and the entire die-casting are fixed at the same time, the combined assembly operation of the entire die-casting can be completed.
