Problems solved by technology

[0004] Although the pyrophyllite powder compacted block improves the sealability and stability of the synthetic mold during synthesis, since the pyrophyllite powder compact is formed by pressing and roasting broken pyrophyllite particles doped with water glass and other substances, the reduction in the process is reduced. The density of pyrophyllite has decreased, resulting in a decline in the pressure transmission performance of pyrophyllite; and now to obtain high-quality diamond, cubic boron nitride, and diamond composite sheets, it is necessary to increase the synthesis pressure in the cavity; the existing technology is limited to the current The top hammer design and the way the pyrophyllite blocks are assembled, a large part of the pressure is lost on the pyrophyllite powder compacted block
[0005] The maximum pressure of the existing pyrophyllite synthesis cavity has never been able to break through 6GPa. After the cavity pressure exceeds 5GPa, most of the load of the six-sided top press is consumed on the sealing edge of the pyrophyllite, and the efficiency of the cavity pressure increases sharply with the load. If the load is further increased, the top hammer will be damaged and the production cost will be greatly increased

[0042] figure 2 According to an exemplary embodiment, it shows a schematic diagram of the structure of a superhard material synthesis mold after press synthesis. As shown in the figure, the first embodiment of the present invention provides a synthetic mold made of superhard material, which includes a block-shaped pyrophyllite mold body 1 , and a through high-pressure mold cavity 10 is provided in the middle of the pyrophyllite mold body 1 . The pyrophyllite matrix 1 is generally cube-shaped with six equal outer surfaces. The high-pressure mold cavity 10 is generally cylindrical, and its axis coincides with a central line of the pyrophyllite mold body 1 . Generally, the surfaces of the pyrophyllite mold body 1 provided with the two openings of the high-pressure cavity 10 are defined as the top surface and the bottom surface. The dolomite composite material ring is generally installed in the high-pressure membrane cavity 10, and the dolomite composite material ring is a circ...

Abstract

The invention discloses a super-hard material synthetic mold. The super-hard material synthetic mold comprises a bulky pyrophyllite mold body. A penetrating high pressure mold cavity is formed in themiddle of the pyrophyllite mold body. Pressurizing sheets are separately embedded onto the four side surfaces of the pyrophyllite mold body. The outer surfaces of the pressurizing sheets are aligned to the outer surface of the pyrophyllite mold body, and the pressurizing sheets are aligned to the high pressure mold cavity. The side faces of the pressurizing sheets are gradually reduced from the outer side of the pyrophyllite mold body to the central direction. The invention relates to the super-hard material synthetic mold, wherein the condition that excessive pyrophyllite powder overflows asa result of excessive deformation of the pyrophyllite is reduced, and included pyrophyllite powder in the gap of a holding-up hammer is reduced.
