[0019] In order to make the purpose, technical solution and advantages of this application clearer, the technical solution in the embodiment will be clearly and completely described below in conjunction with the drawings in the embodiment. Obviously, the described embodiment is only a part of the embodiment of this application, not all embodiments. Based on the given embodiments, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0020] In the description of the present application, it should be understood that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0021] In the description of this application, the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0022] like Figure 1-3 As shown, the structure of the automobile shell is shown, which includes a shell body 12, plug plates 13 and buckles 11 respectively located at both ends of the shell body 12. The buckle 11 has an S-shaped spring structure, and a locking ridge 113 is provided on the side of the end of the buckle 11 away from the shell body 12. Thus, the plug plate 13 is inserted into the opening edge of the cabin body, and the buckle 11 is inserted into the bayonet at the opening edge of the cabin body, thereby closing the cabin body opening. Of course, the buckle 11 can be pulled out of the bayonet by pulling it, and then the automobile shell 10 can be removed. Since the bayonet 11 is an S-shaped structure, it has a first bending area 111, a second bending area 112 and a locking ridge 113.

[0023] like Figure 4-8As shown, the present application discloses an automobile shell mold, including an upper mold 20 and a lower mold 30, the upper mold 20 includes an upper mold plate 21 and an upper mold core 22; the lower mold 30 includes a lower mold plate 31 and a lower mold core 32, and the upper mold core 22 and the lower mold core 32 enclose a mold cavity a; a buckle molding component is arranged on one side of the mold cavity a, specifically, it includes an upper auxiliary molding rod 23, a lower auxiliary molding rod 24 and a side molding die head 26, the upper auxiliary molding rod 23 is connected to the upper mold core 22, and the lower auxiliary molding rod 24 is connected to the lower mold core 32; the upper auxiliary molding rod 23 and the lower auxiliary molding rod 24 are staggered, and the upper auxiliary molding rod 23 is staggered with the lower auxiliary molding rod 24. The outer contour of the head end of the rod 23 is consistent with the inner contour of the first bending zone 111, and the outer contour of the head end of the lower auxiliary molding rod 24 is consistent with the inner contour of the second bending zone 112; the head end of the side molding die 26 is provided with a convex ridge molding groove 113, and is slidably set on the lower template 31, and a driving component drives the side molding die 26 to be linked with the upper mold 20, so that when the upper mold 20 moves downward, the side molding die 26 is driven to move into the mold cavity a, and the upper auxiliary molding rod 23, the lower auxiliary molding rod 24 and the side molding die 26 enclose a snap molding cavity b, and when the upper mold 20 moves upward, the side molding die 26 is driven to move outside the mold cavity a. Among them, the preferred driving component includes a lower inclined surface 261 opened on the side molding die head 26 and an upper inclined surface 211 opened on the upper template 21, the inclined surface 211 is located directly above the lower inclined surface 261 and the upper inclined surface 211 is inclined in the direction of the mold cavity a, and the upper inclined surface 211 is parallel to the lower inclined surface 261. Then, in the process of the upper mold 20 moving toward the lower mold 30, the upper inclined surface 211 contacts the lower inclined surface 261, and the lower inclined surface 261 is squeezed by the upper inclined surface 211 to push the side molding die head 26 to move in the direction of the mold cavity a, thereby realizing the molding of the locking ridge 113 of the buckle 13; it also includes a guide rod 25, a guide hole 262 is opened on the side molding die head 26, the axis of the guide rod 25 and the guide hole 262 are parallel to the lower inclined surface 261, the upper end of the guide rod 25 is fixed on the upper template 21, and the lower end is inserted into the guide hole 262. Therefore, when the injection molding is completed and the upper mold 20 and the lower mold 30 are separated from each other, the guide rod 25 will squeeze the inner surface of the guide hole 262, and then the side molding die head 26 will be moved away from the mold cavity a through the guide rod 25, so that the side molding die head 26 moves in the direction away from the mold cavity a, thereby realizing that after the injection molding is completed, the side molding die head 26 is separated from the car body, which is then conducive to demolding the car body. Of course, at this time, due to the mutual distance between the upper mold and the lower mold, the upper auxiliary molding rod 23 will inevitably be away from the lower auxiliary molding rod 24, that is, the upper auxiliary molding rod 23 will move out of the mold cavity a, and then the ejection mechanism located on the side of the lower mold 30 will eject the car body in the lower mold core 32.

[0024] In addition, in order to facilitate the installation of the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24, in this embodiment, it is preferred that the upper mold core 22 is provided with an upper forming rod channel 221, and the lower mold core 32 is provided with a lower forming rod channel 321, and the upper auxiliary forming rod 23 is inserted into the upper forming rod channel 221 from top to bottom, and the lower auxiliary forming rod 24 is inserted into the lower forming rod channel 321 from bottom to top. Of course, in order to facilitate the disassembly and assembly of the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24, in this embodiment, it is further preferred that the ends of the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24 that are away from the mold cavity a are in contact with the upper mold plate 21 and the lower mold plate 31, respectively, and the two ends are respectively provided with an upper limit portion and a lower limit portion, and the outer contours of the upper limit portion and the lower limit portion are respectively larger than the size of the upper forming rod channel 221 and the lower forming rod channel 321. It should be noted that, on the upper mold core 22, a first countersunk hole is provided at the edge of the upper forming rod channel 221 adjacent to the upper mold plate 21, the upper limit portion is embedded in the first countersunk hole, and the outermost end is flush with the end face of the upper mold core 22; on the lower mold core 32, a second countersunk hole is provided at the edge of the lower forming rod channel 321 adjacent to the lower mold plate 31, the lower limit portion is embedded in the second countersunk hole, and the outermost end is flush with the end face of the lower mold core 32; thus, the upper mold 22 and the lower mold 32 are respectively connected to the upper mold 22 and the lower mold 32. After the template 21 and the lower template 32 are installed, the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24 can be installed and fixed; then when disassembling the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24, it is only necessary to remove the upper mold core 22 and the lower mold core 32 from the upper template 21 and the lower template 31 respectively, and the upper auxiliary forming rod 23 and the lower auxiliary forming rod 24 can be pushed out from the upper forming rod channel 221 and the lower forming rod channel 321 to achieve their disassembly, replacement and maintenance.

[0025] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
