[0019] Example 1

[0020] like Figures 1-2 As shown in the figure, the automobile body die casting part proposed in this embodiment includes an oil pan 1, an engine cylinder block 2, a protective plate 3, and two sets of limiting components.

[0021] The upper opening edge of the oil pan 1 is provided with a first sealing flange 41; the lower opening edge of the engine block 2 is provided with a second sealing flange 42; the second sealing flange 42 and the first sealing flange 41 have a detachable connection structure, and the first sealing flange 41 and the second sealing flange 42 are detachably connected by multiple second bolts 11. The first sealing flange 41 is provided with multiple through holes 411, and the second sealing flange 42 is provided with multiple threaded grooves that are adapted to the second bolts 11. The multiple threaded grooves are provided one-to-one with the multiple through holes 411.

[0022] Two sets of limiting components are symmetrically installed on both sides of the oil pan 1. The limiting components include a limiting frame 5 and an elastic connecting component. The upper part of the limiting frame 5 is "C" shaped. The limiting frame 5 is slidably installed on the first sealing flange 41. The limiting frame 5 is elastically connected to the oil pan 1 through the elastic connecting component. The elastic connecting component includes a guide rod 61, a spring 62 and a limiting block 63. The guide rod 61 is fixedly connected to the side wall of the oil pan 1. The guide rod 61 movably passes through the limiting frame 5. The limiting block 63 is connected to the end of the guide rod 61. The spring 62 is sleeved on the guide rod 61.

[0023] The protective plate 3 is located below the oil pan 1. The protective plate 3 and the oil pan 1 have a detachable connection structure. The protective plate 3 is set to protect the bottom of the oil pan 1 and reduce the probability of it being bumped or scratched. The protective plate 3 and the oil pan 1 are detachably connected by multiple connecting components. The connecting components include a connecting ear plate 7, a first bolt 9 and a threaded tube 10. The connecting ear plate 7 is connected to the protective plate 3, and the threaded tube 10 is connected to the oil pan 1. The first bolt 9 movably passes through the connecting ear plate 7 and is threadedly connected to the threaded tube 10. An outer tube 12 is set on the protective plate 3. A sealing cap 121 is threadedly connected to the outer tube 12. The outer tube 12 is set to protect the drain bolt. After the sealing cap 121 is removed, the drain operation can be easily performed.

[0024] In this embodiment, when installing the oil pan 1, the operator first pulls the limiting brackets 5 on both sides outward, and then aligns the first sealing flange 41 and the second sealing flange 42. After releasing the limiting brackets 5, the upper end of the limiting brackets 5 is stuck on the edge of the second sealing flange 42, thereby achieving the initial limiting of the oil pan 1. This eliminates the need for the operator to lift the oil pan 1 by hand during installation, improving installation efficiency. The second bolt 11 is passed through the through hole 411, and then the second bolt 11 is rotated with the help of a tool, so that the second bolt 11 is threadedly connected to the threaded groove on the second sealing flange 42 until the second bolt 11 is tightened to the limited position. Finally, the other second bolts 11 are fixedly installed in the same way, thereby completing the connection between the first sealing flange 41 and the second sealing flange 42. It should be noted that a sealing ring is also installed at the bottom of the second sealing flange 42. Its purpose is to enhance the sealing between the first sealing flange 41 and the second sealing flange 42 and prevent oil leakage.

[0025] Example 2

[0026] like Figure 1 and Figure 3 As shown in this embodiment, compared to Embodiment 1, this embodiment proposes a die-cast automotive body. In this embodiment, multiple L-shaped sliding parts 8 are vertically slidably installed on the side wall of the oil pan 1. Multiple second bolts 11 are correspondingly arranged with the multiple L-shaped sliding parts 8. The second bolt 11 includes a screw body 111, a hexagonal head 112, and a connecting post 113 connecting the screw body 111 and the hexagonal head 112. The diameter of the connecting post 113 is smaller than the diameter of the screw body 111. A limiting hole 81 is opened on the L-shaped sliding part 8, and the connecting post 113 is rotatably arranged inside the limiting hole 81. The second bolt 11 is rotatably installed on the L-shaped sliding part 8, and the L-shaped sliding part 8 can slide vertically on the side wall of the oil pan 1. After the second bolt 11 is disassembled, it will not fall off, which can avoid the loss of the second bolt 11. In addition, the tedious alignment work of the second bolt 11 can be eliminated in the subsequent installation process, thus improving the installation efficiency.

[0027] Example 3

[0028] like Figure 2 As shown in the figure, the automobile body die casting proposed in this embodiment has a funnel structure at the bottom of the inner cavity of the oil pan 1 compared to the first embodiment. Compared to the traditional planar arrangement of the inner cavity, this arrangement makes it less likely for debris in the oil to accumulate at the bottom of the inner cavity of the oil pan 1. As the oil is drained, a large amount of debris will be discharged, improving the cleanliness when the oil is injected next time.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
