Problems solved by technology

The stamping process of the rear tailgate cover is complicated, and has the following disadvantages: the rear tailgate cover is generally stamped with a whole piece of metal material, so that the overall rigidity will be reduced, the durability will be reduced, and it will be deformed after a long time; if you choose Metal that is too rigid may break after a stamping process
However, the molds used in stamping processing are generally more complicated, so the manufacturing cycle is long and the cost is high.

Embodiment 1

[0026] Such as figure 1, figure 2 As shown, the present invention is an automobile tailgate assembly, which includes an integrally injection-molded tailgate panel. The inner wall of the tailgate panel is provided with a locking structure connected to the tailgate lock of the rear wall panel of the vehicle body. The locking structure is close to the tailgate panel and its free The inner wall of the tailgate panel is fixedly provided with a hinge shaft hinged with the rear end of the roof; the tailgate panel is clamped with a taillight box.

[0027] The process of processing the automobile tailgate in the automobile tailgate assembly includes the following process steps:

[0028] S1: Material preparation: The amount of material to be prepared is based on the ratio of polycarbonate and ABS plastic ×: ×, and the proportion of recycled materials is less than 10%;

[0029] S2: Use a dehumidifier to dry the prepared materials, use a moisture meter to detect the moisture content of...

Embodiment 2

[0043] The difference from Embodiment 1 is that, as image 3 , Figure 8 As shown, the specific parameters for making the tailgate for the Lynk & Co DCY11 model are as follows:

[0044] Material requirements:

[0045] Tailgate cover outer panel: PC+ABS HAC8265G (black)

[0046] Tailgate cover inner panel: PC+ABS HAC8265G (black)

[0047] The material meets the requirements of "E-TP-GEELY801";

[0048] Before injection molding, raw material drying requirements: 95-105°C, 4-6h;

[0049] Ontology requirements:

[0050] product weight:

[0051] The weight of the plastic part of the outer panel of the tailgate cover: 1252±5g, the weight of the plastic part of the inner panel of the tailgate cover: 924±5g.

Embodiment 3

[0053] The difference from Embodiment 1 is that, as Figure 4 to Figure 7 shown (for ease of illustration, Figure 4 Blind holes and elastic friction layers are not shown; Figure 5 spring not shown; Figure 6 Blind holes are not shown; Figure 7 The blind hole and the elastic friction layer are not shown), the tailgate plate 1 is provided with a through hole 2, the through hole 2 is arranged near the free end of the tailgate plate 1, the through hole 2 is triangular prism or prism shape and the large size of the through hole 2 The end faces to the outside of the vehicle body, and is fitted with the through hole 2 to form a triangular prism-shaped locking member 3 hinged on the rear panel of the vehicle body. The vertical cross-sectional shape of the through hole 2 parallel to the traveling direction of the car body is trapezoidal, and the angle between the waist of the trapezoid and the horizontal plane near the wheel is smaller than the angle between the other waist and t...

Abstract

The invention discloses an automobile tail gate assembly which comprises an integrated injection molding tail gate plate. A locking structure is arranged on the inner wall of the tail gate, wherein the locking structure is connected with a tail gate lock of a automobile body rear end plate, the locking structure is arranged close to the free end of the tail gate plate, and a hinge shaft hinged tothe rear end of the automobile roof is fixedly arranged on the inner wall of the tail gate plate; and a taillight box is arranged on the tail gate plate in a clamping mode. The invention further discloses a processing technology of the tail gate, a metal material is changed into plastics, so that the weight is reduced, the stamping difficulty is reduced, and molding is diversified; stamping is changed into an injection molding technology; compared with the metal material, plasticity of the plastics is higher; and the purpose that the tail gates are closed more tightly when automobiles are driving on bad roads is achieved.

Description

technical field [0001] The invention relates to an automobile tailgate assembly and a processing technology thereof. Background technique [0002] Because the metal material needs to be completed by stamping technology, and the structure and shape of the rear tailgate cover is more complicated, the requirements for the stamping machine and stamping die are also higher, so that Jinan can realize the diversification of the shape of the rear tailgate cover. The stamping process of the rear tailgate cover is complicated, and has the following disadvantages: the rear tailgate cover is generally stamped with a whole piece of metal material, so that the overall rigidity will be reduced, the durability will be reduced, and it will be deformed after a long time; if you choose Metals that are too rigid may break after a stamping process. Therefore, first of all, in the selection of metal materials, it is necessary to ensure both rigidity and sufficient toughness, which increases the ...
