[0024] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 An auxiliary heating mechanism 9 is provided on the lower mold body 1, and the auxiliary heating mechanism 9 includes a heating ring 91. The inner side of the lower mold body 1 is in contact with the heating ring 91, and the inner side wall of the lower mold body 1 is fixedly connected to a fixing frame 92, and the inner wall of the fixing frame 92 is slidably connected to a telescopic frame 93.
