The bottom of the side of the lower mold 110 is assembled and fastened to the heating platform 120 by screws, thereby facilitating the assembly and disassembly of the lower mold 110 and making subsequent maintenance more convenient.

[0026] As a more detailed description of this embodiment, a heating disc 121 is mounted in the middle of the upper surface of the heating platform 120, and a groove corresponding to the heating disc 121 is opened in the middle of the upper surface of the heating platform 120, and the outside of the heating disc 121 is electrically connected to the corresponding control module through a wire, so as to facilitate the use of the heating platform 120 to heat and control the lower mold 110. It should be noted that the existing market for relevant heating components and control modules is basically mature, and finished products can be purchased according to the needs of use for assembly and docking.

[0027] As a more detailed description of this embodiment, isolation plates 122 are provided around the outer side of the heating platform 120, and a through-slot 123 corresponding to the isolation plate 122 is fixed to the inner side wall of the lower column 152, and the isolation plate 122 is inserted and assembled in the center above the through-slot 123. In this way, when in use, it is convenient to block the outer side of the heating platform 120, relatively avoid or reduce accidental injuries caused by foreign objects, and make it safer to use;

According to the forging requirements of the special-shaped forging, the appropriate special-shaped groove 111 and the lower die 110 are selected and assembled on the surface of the hot temperature table 120 for operation forging. During forging, the temperature of the hot temperature table 120 and the lower die 110 is kept constant by the heating of the heating plate 121. It is convenient to heat and increase the temperature so that it is relatively stable and equal to the temperature of the forging, which is convenient for subsequent continuous forging to ensure product quality. During operation, the side baffle 160, the front frame 170 and the front baffle door 171 cooperate to isolate the forging area to form a corresponding isolation area, making the operation safer and convenient for heat preservation.
