The air extractor 209 is used to extract the hot air inside the device.

[0027] In this embodiment: The pressure application and heating mechanism 3 includes a cylinder body 301 arranged above the inner side of the auxiliary mechanism 2. Heat conduction grooves 302 are vertically and equidistantly arranged on the inner wall of the cylinder body 301. A bottom hydraulic cylinder 303 is installed inside the cylinder body 301. A second mounting plate 304 is installed at the power end of the bottom hydraulic cylinder 303. A vertical plate 305 is arranged above the second mounting plate 304. A horizontal pressing assembly is installed on the vertical plate 305. A connecting platform 307 is arranged on the cylinder body 301, and an external connecting thread 3071 is arranged on the outer surface of the connecting platform 307. A combustion heating assembly is arranged inside the cylinder body 301. A table body 311 is arranged below the combustion heating assembly. A heat conduction pipe 312 is installed on the table body 311. An upper hydraulic press 308 is installed inside the cylinder body 301, and a pressing plate 313 is arranged at the power end of the upper hydraulic press 308. The pressing plate 313 is used to apply pressure to the graphite powder block after being heated to a high temperature. The horizontal pressing assembly includes a horizontal hydraulic rod 306 arranged on the vertical plate 305, and a horizontal pressing plate 3061 is installed at one end of the horizontal hydraulic rod 306. The combustion heating assembly includes a burner 309 arranged inside the cylinder body 301, and a heating plate 310 is installed on the burner 309. The burner 309 is used to create a high-temperature environment inside the cylinder body 301, which is a prior art. An automatic pressure relief valve is installed on the cylinder body 301, which can maintain the pressure stability inside the cylinder body 301 and can effectively prevent related components from being damaged by pressure.

[0028] Working principle: During use, first place the graphite powder block on the upper side of the second mounting plate 304. Start the lifting hydraulic cylinder 204 to drive the first mounting plate 2041 and the synthesis cylinder cover 206 to move downward. When the synthesis cylinder cover 206 is combined with the cylinder body 301, start the frequency conversion motor 205 to slowly rotate clockwise, and rotate and connect the synthesis cylinder cover 206 with the external connection thread 3071 provided on the outer surface of the connection platform 307 above the cylinder body 301 through the internal connection thread 207, so that the cylinder body 301 forms a sealed space. Start the bottom hydraulic cylinder 303 to raise the second mounting plate 304. The horizontal pressing plate 3061 restricts the position of the graphite block to prevent it from falling. Start the upper hydraulic press 308 to lower, driving the pressing plate 313 to lower and cover the graphite block. At the same time, start the horizontal hydraulic rod 306 to push the horizontal pressing plate 3061 inward. As the pressing plate 313 and the horizontal pressing plate 3061 are completely attached to the graphite block, the burner 309 is turned on and provides heat to the pressed graphite block through the heating plate 310 and the heat conduction pipe 312. And as the heat is continuously supplied, the temperature inside the cylinder body 301 gradually rises, making the cylinder body 301 form a high-temperature and high-pressure environment, and the synthesis of diamonds begins. After processing, the pressing plate 313 and the horizontal pressing plate 3061 are retracted, and the heat dissipation component is turned on to eliminate the hot air inside the cylinder body 301. The frequency conversion motor 205 rotates counterclockwise, opens the synthesis cylinder cover 206, and takes out the diamonds. Heat conduction grooves 302 are provided on the inner wall of the cylinder body 301, increasing the heat storage area of the inner wall of the cylinder body 301 and preventing heat from escaping, so as to make the best use of thermal energy and avoid rapid heat loss.
