[0002] During the high-temperature, high-pressure diamond cultivation process, the pressure-transmitting medium plays a crucial role in the synthesis efficiency, product quality, and production safety. Pyrophyllite blocks are a widely used pressure-transmitting medium. Due to the limitations of traditional pyrophyllite blocks during use, new pyrophyllite blocks with built-in sealing edges can improve pressure utilization and reduce the risk of overflow within the synthesis block. However, these pyrophyllite blocks with built-in sealing edges are often difficult to press and demold, and existing pressing molds struggle to meet the demands of fast and efficient demolding.

[0029] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.
[0030] like Figure 1-2 As shown, the present invention provides a hinged mold for pressing pyrophyllite blocks with self-sealing edges, comprising a female mold 6, an upper pressing head 1, side plates 2, and a base 5. The lower end of the female mold 6 is fixedly connected to the workbench of a four-column hydraulic press. A square through-hole 60 is vertically formed through the middle of the female mold 6, and the upper pressing head 1, side plates 2, and base 5 are arranged in the through-hole 60 for vertical movement.
[0031] like Figure 3 As shown, the upper portion of the upper pressure head 1 is fixedly connected to the upper piston of the four-column hydraulic press via a first fixed end 11. During the pressing process, the upper pressure head 1 is driven by the upper piston of the four-column hydraulic press to move up and down. The bottom of the upper pressure head 1 is the pressing end, which is used to press the pyrophyllite block 4. The side wall of the upper pressure head 1 is provided with a vent hole 13 connected to the perforation 10. The main function of the vent hole 13 is to balance the air pressure so that the interior of the upper pressure head 1 is balanced with the atmospheric pressure. The upper pressure head 1 is designed as a square cylinder.
[0032] like Figure 7 As shown, the base 5 is a one-piece forging. The base 5 is square in shape, matching the shape of the through hole 60, and its lower end is fixedly connected to the ejection device of the piston at the bottom of the four-column hydraulic press via a second fixed end 61. Four mutually cooperating side panels 2 are provided above the base 5. The lower ends of the side panels 2 are hinged to the base 5 via cooperating hinge ears 23 and a pin. Each side panel 2 cooperates with the corresponding surface of the square through hole 60. The base 5 is provided with a hinged ear seat that corresponds to the hinge ear 23. After the base 5 is installed in the through hole 60, the hinged ear seat is located in a slide groove 601 provided on the inner wall of the through hole 60.
[0033] During demoulding, the side panels 2 and the pyrophyllite block 4 with its own sealing edge 41 can be ejected together by the base 5. Since the side panels 2 are hinged to the base 5 at the bottom, the four side panels 2 can be opened in all directions by the hinge structure after being ejected out of the through hole 60. The hinged structure design of the side panels 2 not only allows the pyrophyllite block 4 with its own sealing edge 41 to be quickly demoulded after pressing, thereby improving production efficiency, but also improves operational safety and prevents the mold from cracking during the pressing process.
[0034] The side plate 2 is slidably mounted on the inner wall of the through hole 60. Figure 4 and 6 As shown, a vertically connected slot 601 is formed in the inner wall of the through hole 60. A protrusion 22 is fixed to the outer wall of the side panel 2. The protrusion 22 slides vertically into the slot 601. The protrusion 22 and the slot 601 are designed to cooperate with each other in a trapezoidal shape. The trapezoidal protrusion 22 slides up and down in the slot 601 of the female mold 6, guiding the side panel 2 as it moves up and down, ensuring its stability during the pressing process.
[0035] In addition, both side edges of the side panels 2 are provided with bevel tips 21 , and the bevel tips 21 of two adjacent side panels 2 cooperate with each other to form a pressing groove 24 , which is used to press the sealing edge 41 of the pyrophyllite block 4 .
[0036] like Figure 5 As shown, the top of the base 5 is provided with a draw-in slot 50 downwards, and the bottom card of the center column 3 is placed in the draw-in slot 50, which makes the installation and disassembly of the center column 3 simpler and more convenient, and can also prevent the center column 3 from offsetting during the pressing process, causing the size of the self-carrying dense edge phyllite block 4 to deviate. During the pressing process, the center column 3 remains motionless, forming a square cavity inside the phyllite block 4. When the base 5 is ejected, the center column 3 is also ejected. When the center column 3 is ejected to the appropriate position, the side panel 2 is opened, and the press-molded phyllite block 4 is sleeved on the center column 3. Remove the center column 3 and the phyllite block 4 can be demoulded.
[0037] like Figure 8 and 9As shown, a pressing cavity is formed between the base 5, the center column 3 and the surrounding side plates 2, and the square cylindrical upper pressure head 1 matches the shape of the pressing cavity, and the pressing end of the upper pressure head 1 is vertically and movably inserted into the pressing cavity; the middle part of the upper pressure head 1 is provided with a through hole 10 that matches the shape of the center column 3, and the center column 3 is vertically and movably inserted into the through hole 10. After the phyllite block 4 raw material is placed in the pressing cavity, the pressing operation is performed by the downward movement of the upper pressure head 1. The phyllite block 4 with a self-sealing edge 41 pressed and formed by the mold of the present application can improve the pressure transmission stability of the phyllite block 4 during the process of synthesizing diamonds under high temperature and high pressure environment, prevent the occurrence of overflow, and reduce the risk of explosions.
[0038] A protruding edge 12 is fixedly provided on the outer wall of the upper pressing head 1, and the protruding edge 12 is shaped to match the pressing groove 24. The protruding edge 12 is vertically movably inserted into the pressing groove 24. The cooperation between the protruding edge 12 and the pressing groove 24 can press and form the sealing edge 41 of the pyrophyllite block 4, thereby significantly improving the pressing quality and efficiency of the sealing edge 41 of the pyrophyllite block 4, and the pressing effect of the sealing edge 41 of the pyrophyllite block 4 is better.
[0039] When using the utility model, the pyrophyllite material to be pressed is filled in the pressing cavity formed by the side panels 2, the center column 3 and the base 5 to ensure the sufficiency of the pyrophyllite material; the upper pressure head 1 is connected to the upper end of the four-column oil press and adjusted to the position so that it is aligned with the pressing cavity filled with the pyrophyllite material below; the four-column oil press is started, and the upper pressure head 1 starts to move downward under the drive of the oil press to press the pyrophyllite material; after the upper pressure head 1 moves downward to set the stroke, it moves upward to reset; the lower piston of the four-column oil press is started, pushing the base 5 to move upward, so that the base 5, the side panels 2 and the center column 3 move upward synchronously along the through hole 60 of the briquetting female mold 6, and after the base 5 moves upward to the set stroke, the side panels 2 are opened to the surroundings by a hinged structure. The pyrophyllite block 4 that has been pressed and formed is removed from the base 5, and the center column 3 in the pyrophyllite block 4 is taken out and the pyrophyllite block 4 is polished to the standard size.
