During long-term use, the sliding column 12 can further improve the stability during use and avoid problems such as deformation caused by the offset of the mold 20 and the upper die 8.

[0024] Please refer to Figure 1 - Figure 3, a fixed plate 11 is fixedly connected to the lower surface of the mold 20, and the lower surface of the upper mold 8 is fixedly connected to the upper surface of the fixed plate 11; a fixed slot 18 is provided on the inner wall of the fixed plate 11, and the outer wall of the fixed plate 11 is slidably connected to the inner wall of the combined table 7, and a protective shell 13 is fixedly connected to the outer wall of the combined table 7; a plug rod 15 is slidably connected to the inner wall of the protective shell 13, and a limit slot 19 is provided on the inner wall of the combined table 7; the outer wall of the plug rod 15 is slidably connected to the inner wall of the fixed slot 18, and the outer wall of the plug rod 15 is slidably connected to the inner wall of the limit slot 19;
