[0023] Through the above technical scheme, working cavity 2 is opened in the top of body 1 for forming assembly to install and work, and first support plate 32 and second support plate 33 are designed as two ends narrow in the middle, so that upper die 3 and lower die 31 can be better installed, and upper die 3 is controlled by hydraulic drive equipment, so that two moulds are combined, and upper die 3 and lower die 31 are installed by second mounting hole 35 and first mounting hole 34 respectively, and operating personnel can quickly disassemble and replace mould according to different forming processing needs, to improve the convenience of device use.

[0024] Please refer to Figure 2 、 Figure 3 And Figure 4 Buffer assembly further includes two first fixed column 42 and second fixed column 45, and two first fixed column 42 and second fixed column 45 are fixedly connected at the bottom wall both ends of first mounting plate 4 and the top wall both ends of second mounting plate 41 respectively, and the top wall of second fixed column 45 is equipped with the plug-in groove 46 matched with first fixed column 42, and the inner top wall of first fixed column 42 is fixedly connected with spring 43, and the tail end of spring 43 is fixedly connected with sliding plate 44, and the top of second fixed column 45 is fixedly connected with protruding column 47;The inner wall of body 1 is equipped with inner cavity 5, and inner cavity 5 is arranged around working cavity 2, and working cavity 2 is communicated with inner cavity 5 through a plurality of rectangular array distribution through slot 6.

[0025] Through the above technical scheme, first fixed column 42 and second fixed column 45 move synchronously towards each other when upper die 3 and lower die 31 are closed, since plug-in groove 46 and first fixed column 42 are matched, protruding column 47 drives sliding plate 44 to move upwards through spring 43, and the impact force is buffered through the elastic force of spring 43, so that the influence of impact force on mould when upper die 3 and lower die 31 are combined is reduced.

[0026] Please refer to Figure 2 ,Figure 5 and Figure 6 The inner cavity 5 is provided with an electric heating tube 7 at both the front and rear ends; the bottom of the body 1 is provided with an inner groove 8, and the top of the inner groove 8 is provided with a cross-shaped air duct 10, which is communicated with the inner cavity 5; the inner groove 8 is provided with a cooling fan 9 at both ends.

[0027] Through the above technical scheme, the electric heating tube 7 is started by the driver, and hot air penetrates into the working cavity 2 through the through groove 6. Since the inner groove 8 is communicated with the inner cavity 5 through the air duct 10, the cooling fan 9 can send cold air into the working cavity 2 through the air duct 10. The hot air and the cold air contact the surface of the mold to realize heating or cooling during the molding of the mold, so that different temperature control requirements can be selected according to different use requirements, and the molding effect of the graphite mold is further ensured.

[0028] Working principle: when the graphite mold is molded, the corresponding mold is selected according to the size of the graphite mold to be molded. The upper mold 3 and the lower mold 31 are respectively connected with the output end of the driving device and the inner bottom wall of the body 1 through the second support plate 33 and the first support plate 32. The upper mold 3 and the lower mold 31 can be stably combined through the driving device.

The protruding column 47 at the top of the second fixed column 45 is in contact with the sliding plate 44. The first fixed column 42 will make the protruding column 47 drive the sliding plate 44 to press upward during the downward movement. Since the sliding plate 44 is connected with the first fixed column 42 through the spring 43, the impact force generated when the upper mold 3 and the lower mold 31 are combined can be buffered through the elastic force of the spring 43, thereby improving the service life of the mold. At the same time, the inner cavity 5 is provided in the body 1 along the outside of the working cavity 2. The inner cavity 5 is communicated with the working cavity 2 through the through groove 6 and communicated with the inner groove 8 through the air duct 10. When heating is needed during the molding of the mold, the electric heating tube 7 is started. The heat generated by the electric heating tube 7 heats the surrounding environment. Hot air enters the working cavity 2 through the through groove 6, so as to contact the outer surfaces of the upper mold 3 and the lower mold 31, thereby realizing the heating effect. Two cooling fans 9 are installed in the inner groove 8. The cooling fans 9 can send cold air from the air duct 10 into the inner cavity 5. The electric heating tube 7 is cooled at the same time, and the cooling fans 9 also enter the working cavity 2 through the through groove 6, thereby realizing the cooling effect of the mold surface. The combination of heating and cooling further ensures the efficiency and quality of the molding of the graphite mold.
