The bottom of the inner side surface of the guide groove 4 is slidably connected with a second connecting piece 5. One side of the outer surface of the second connecting piece 5 is threadedly connected with a lower die base 6. Both sides of the outer surface of the upper die base 1 are threadedly connected with first bolts 7. One side of the outer surface of the first bolts 7 is movably connected with a connecting plate 8. The middle part of the outer surface of the connecting plate 8 is fixedly connected with a connecting rod 9. One side of the outer surface of the connecting rod 9 is movably connected with a slide block 10 through a nut. The inside of the slide block 10 is slidably connected with a first guide rod 11.

[0027] During specific use, through the settings of the guide plate 3, the guide groove 4, the second connecting piece 5, the connecting rod 9, the slider 10 and the first guide rod 11, the guide plate 3 is attached to the upper die base 1 and the lower die base 6. The guide plate 3 is fixed on the outer surface of the upper die base 1 through the first connecting piece 2, and the second connecting piece 5 is threadedly connected to the outer surface of the lower die base 6. Inside the guide groove 4, when the mold is closed, the guide plate 3 moves downward, and the guide groove 4 slides on the outer surface of the second connecting piece 5 accordingly, thereby limiting both sides of the mold. It can play a role in precise guidance during the process of mold opening and closing, ensuring the accuracy of workpiece forming. The connecting plate 8 is fixed on the outer surface of the upper die base 1 through the first bolt 7. The slider 10 is slidably connected to the outer surface of the first guide rod 11. At the same time, the connecting rod 9 is fixed on the outer surface of the slider 10 through a nut, and the length of the connecting rod 9 can be adjusted according to the size of the mold, enhancing the applicability. When the upper die base 1 moves, the connecting rod 9 drives the slider 10 to slide on the outer surface of the first guide rod 11, limiting and guiding the upper die base 1, avoiding deviation or shaking during the up and down movement, ensuring the stable operation of the mold, having multiple limiting effects, making the mold more stable, and ensuring the quality of the processing of the automobile trunk assembly.

[0028] In this embodiment, positioning columns 12 are fixedly connected to the four corners of the lower surface of the upper die base 1, and positioning holes 13 are formed at the four corners of the upper surface of the lower die base 6.

[0035] During specific use, through the setting of the cylinder 19, the cylinder 19 is fixed on the upper surface of the top plate 18, and its output end is connected to the support plate 20. When the output end of the cylinder 19 expands and contracts, the upper die holder 1 can be driven by the support plate 20 to move up and down to complete the production and processing operations.

[0036] In this embodiment, the second bolts 21 are threadedly connected to the upper surfaces of the support plate 20 and the upper die holder 1, and the third bolts 22 are threadedly connected to the upper surface of the lower die holder 6.

[0037] During specific use, through the setting of the second bolts 21 and the third bolts 22, the two are used to fix the upper die holder 1 and the lower die holder 6 to ensure the firmness of use, so that the mold has the function of being convenient for disassembly and replacement, facilitating the replacement of different molds according to different automobile trunk components, and increasing the applicability and practicality.
