[0002] Diamond cultivation mainly uses high temperature and high pressure methods and chemical vapor deposition methods. The carbon source crystallizes on the seed crystal, and the stone is formed in several weeks. It has the same composition and characteristics as natural diamonds. The common diamond insulation material encapsulation structure often uses pyrophyllite as the matrix, with an internal graphite heating element and metal sleeve, which wraps the carbon source and seed crystal to achieve heat preservation, pressure transmission and sealing, and is suitable for high temperature and high pressure environments.

[0003] In existing technologies, some heat-insulating structures for diamond cultivation include heat-insulating layer materials, isolation chambers, and top-pressure equipment. The working principle is to prevent heat from radiating and conducting outward through the heat-insulating layer, the isolation chamber provides a high-temperature, high-pressure, and chemical vapor deposition cultivation environment, and the top-pressure equipment stably provides pressure and heat energy to ensure the orderly conversion of carbon sources into diamond crystals.

[0004] In existing technologies, some thermal insulation structures for diamond cultivation are difficult to accommodate multiple carbon sources simultaneously, and harmful impurities can easily contaminate the cavity. Therefore, a thermal insulation material encapsulation structure for lab-grown diamonds is proposed to solve the above problems. Utility Model Content

The inside of each of the multiple heating tubes is slidably connected to two salt tubes, the inside of each of the two salt tubes is slidably connected to a metal cup, and the inside of the metal cup is slidably connected to a filling component. As a further description of the above technical solution: The top-pressing mechanism includes multiple protective shells. The bottom of each protective shell is fixedly connected to the top of the support column. Multiple hinge beams are fixedly connected to the outside of each protective shell. Two hinge beams are fixedly connected to the outside of each protective shell. A pin is rotatably connected inside each hinge beam. An oil passage hole is provided inside the protective shell. As a further description of the above technical solution: The conductive ring has multiple plugs that slide inside, and a carbon source is placed inside the metal cup. As a further description of the above technical solution: The filling component includes a metal block, the outside of which is slidably connected to the inside of the metal cup, and a plurality of extrusion blocks are fixedly connected to the outside of the metal block; As a further description of the above technical solution: Each of the multiple protective shells has an oil cavity fixedly connected inside, and the oil cavity has multiple threaded holes on its outside; As a further description of the above technical solution: A piston is slidably connected inside the threaded hole, and a top hammer is fixedly connected to the outside of the piston; As a further description of the above technical solution: Each of the multiple threaded holes is externally threaded with a screw, and the screw is externally threaded with a guide ring.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the carbon source is rapidly heated by the combination of the conductive ring and the heating tube. Multiple sets of diamond cultivation equipment are placed through the multiple holes opened inside the pyrophyllite. The salt block replaces the ordinary heat preservation material, which reduces the easy contamination of the cavity by harmful impurities and reduces costs compared with the prior art.

[0008] 2. In this utility model, by controlling the liquid volume inside the oil chamber, the piston is pushed to move, thereby causing multiple top hammers to simultaneously squeeze the outside of the pyrophyllite. The guide ring is fixed to the outside of the oil chamber by screws, which increases the sealing of the oil chamber. Compared with the prior art, this achieves the effect of efficiently pushing the top hammers. Attached Figure Description

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] The encapsulation structure of thermal insulation material for lab-grown diamonds, refer to Figures 1 to 3 The system includes pyrophyllite 1, with a synthesis mechanism 2 slidably connected inside pyrophyllite 1. Pyrophyllite 1 serves as the pressure-bearing and heat-insulating substrate for synthesis mechanism 2. A top-pressure mechanism 3 is placed outside synthesis mechanism 2, which can apply uniform pressure to synthesis mechanism 2 to meet the high-pressure requirements of diamond cultivation. A support column 4 is fixedly connected to the bottom of top-pressure mechanism 3, which provides stable support for top-pressure mechanism 3 and ensures the stability of the overall structure during pressure application. Synthesis mechanism 2 includes multiple conductive rings 21, which are used to connect to the power supply to form a current loop and provide power support for heating. The conductive rings 21 are slidably connected to the outside of pyrophyllite 1. A heating tube 22 is slidably connected inside conductive rings 21. After conductive rings 21 conduct electricity, the heating tube 22 generates Joule heat, providing a high-temperature environment for diamond cultivation. Two salt tubes 23 are slidably connected inside heating tube 22. Salt tubes 23 have good heat insulation performance, reduce heat loss from heating tube 22, can replace ordinary heat insulation materials, and can reduce the easy contamination of the cavity by harmful impurities. Specifically, the support column 4 provides stable support for the top pressure mechanism 3, which applies uniform pressure to the synthesis mechanism 2 inside the pyrophyllite 1. After the conductive ring 21 is energized, the current is conducted through it to the heating tube 22 to generate Joule heat. The salt tube 23 wraps around the heating tube 22 to reduce heat loss. The pyrophyllite 1 serves as the substrate to withstand pressure and assist in heat preservation. The sliding connection of each component facilitates assembly and works together to form a high temperature and high pressure environment, which meets the conditions for diamond cultivation. The salt tube 23 can also reduce impurity contamination.

[0013] Reference Figure 1 and Figure 3Multiple plugs 24 are slidably connected inside the conductive ring 21. The plugs 24 can seal the internal space of the conductive ring 21 to prevent heat and pressure leakage. Metal cups 25 are slidably connected inside the two salt tubes 23. The metal cups 25 provide a reaction vessel for the conversion of carbon source 26 and conduct heat to make the internal temperature uniform. The carbon source 26 is placed inside the metal cup 25. The carbon source 26 will be converted into diamond crystal under high temperature and high pressure. A filling component 27 is slidably connected inside the metal cup 25. The filling component 27 includes a metal block 271. The metal block 271 can transmit pressure to the carbon source 26 to ensure the high pressure state of the environment in which the carbon source 26 is located. The outside of the metal block 271 is slidably connected inside the metal cup 25. Multiple extrusion blocks 272 are fixedly connected to the outside of the metal block 271. The multiple extrusion blocks 272 increase the contact area with the carbon source 26 and make the pressure transmission more uniform. Specifically, the plug 24 slides to seal the inside of the conductive ring 21 to prevent heat and pressure leakage. The metal cup 25 inside the salt tube 23 conducts heat, so that the internal carbon source 26 is heated evenly. The metal block 271 of the filling component 27 slides inside the metal cup 25, driving the extrusion block 272 to compact the carbon source 26, increasing the contact area and making the pressure transmission more even. Under high temperature and high pressure, they work together to promote the transformation of the carbon source 26 into diamond crystals.

[0014] Reference Figure 1 , Figure 2 and Figure 4 The pressing mechanism 3 includes multiple protective shells 31. Multiple hinge beams 32 are fixedly connected to the outside of each protective shell 31. The hinge beams 32 enhance the structural strength of the protective shell 31 and facilitate coordinated force distribution among its components. Two hinge beams 33 are fixedly connected to the outside of each protective shell 31. Pins 34 are rotatably connected inside the hinge beams 33, enabling the connection of multiple pressing devices. An oil passage 35 is provided inside each protective shell 31 to deliver hydraulic oil to oil chambers 36, which are fixedly connected inside each of the multiple protective shells 31, providing power for the movement of the piston 38. The oil chambers 36 are... The piston 38 is provided with multiple threaded holes 37, and screws 311 are threaded to the outside of each threaded hole 37. The threaded holes 37 provide an installation position for the piston 38, and the threaded connection with the screws 311 ensures a sealed fit inside the oil chamber 36. A guide ring 310 is threaded to the outside of the screws 311. The guide ring 310 provides guidance for the movement of the piston 38, ensuring the stability and accuracy of the piston 38's movement. The piston 38 is slidably connected inside the threaded holes 37. The piston 38 moves under the push of hydraulic oil, thereby driving the top hammer 39 fixedly connected to the outside of the piston 38 to move. Specifically, the protective shell 31 is strengthened by the hinge beam 32, and multiple sets of equipment are connected to the pin 34 via the hinge beam 33. The oil passage 35 sends hydraulic oil to the oil chamber 36, which pushes the piston 38 in the threaded hole 37 to slide. The guide ring 310 fixed by the screw 311 ensures that the piston 38 moves smoothly, thereby driving the top hammer 39 to apply pressure synchronously. All components work together to achieve stable and efficient pressure output.

The guide ring 310 is fixed to the outside of the oil chamber 36 by multiple screws 311 to seal the inside. The amount of oil inside the oil chamber 36 is controlled by the oil passage 35, thereby pushing the piston 38 to move, which in turn pushes the hammer 39 to move, so that multiple hammers 39 simultaneously squeeze the pyrophyllite 1 and the synthesis mechanism 2 to grow diamonds.
