DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] like Figure 1-7 As shown, an EPS packaging box for the rear wall of a car includes:

[0029] A plurality of packaging layers 1 are stacked in the vertical direction, and a plurality of small holes 9 are provided on the bottom surface of each packaging layer 1. Each packaging layer 1 includes a spliced ​​foam box 11 and a foam box 2 12. A notch 8 is provided on the side of each foam box 11 and a foam box 2 12, which is a fixed position of the packing bag. An assembly component 13 for assembling the foam box 11 and the foam box 2 12 is connected between the foam box 11 and the foam box 2 12. A plurality of concave cavities 5 for accommodating the rear enclosure 4 of the automobile are provided in each packaging layer 1. A material reduction part 6 is provided in the cavity 5. The cavity 5 on the side away from the foam box 2 12 in the foam box 1 11 is provided as an empty cavity 10. The advantage of this is that since a small structure will directly protrude from the rear enclosure 4 of the automobile during packaging, if the empty cavity 10 is not provided and the forming cavity 5 is directly provided, the workpiece will be in contact in the upper and lower directions and will be easily deformed. After the empty cavity 10 is provided to directly avoid air, the upper and lower directions of the foam packaging can be made into annular ribs, thereby improving the strength.

[0030] Two paper covers 2 are respectively connected to the two packaging layers 1 at the top and the bottom. The two paper covers 2 completely wrap the upper and lower end surfaces of the multiple packaging layers 1. A plurality of small holes 9 are provided on the bottom surface of each packaging layer 1. Since each layer needs to be sprayed with anti-rust oil after the parts are packaged, liquid will accumulate at the position of the cavity 5 where the parts are placed. The residual liquid can be discharged to the bottom layer through the small holes 9.

[0031] The base 3 is connected to the bottom of the paper cover 2 located at the lower side.

[0032] The material reduction part 6 includes a plurality of connecting holes 61 opened at the bottom of the cavity 5 and a molding platform 62 located on both sides of the cavity 5. The molding platform 62 is configured as a shell structure and is against both sides of the rear panel 4 of the automobile. The plurality of connecting holes 61 are arranged at equal distances, so that the weight of the foam can be effectively reduced when the rear panel 4 of the automobile is positioned.

[0033] The assembly component 13 includes a plurality of snap-fitting portions 131 arranged on the side of the foam box 11 and a plurality of protrusions 132 arranged on the side of the foam box 2 12. The protrusions 132 are provided with snap-fitting grooves 133 which cooperate with the snap-fitting portions 131. Each snap-fitting portion 131 is composed of no less than two square protrusions. In this way, the packaging layer 1 can be composed of two mutually snap-fitting foam boxes 11 and 12, thereby reducing the processing difficulty of the long strip of foam and improving the processing quality of the foam, while avoiding reducing the transportation quantity of each layer.

[0034] The mold cavity 5 includes an upper mold surface 51 located on the upper side of the packaging layer 1 and a lower mold surface 52 located on the lower side of the packaging layer 1. An opening 53 is provided in the middle of each mold cavity 5. Each mold cavity 5 is provided with a partition 54 for separating multiple mold cavities 5. A notch 7 is provided on the top of each partition 54 to avoid interference between the upper and lower workpieces.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
