[0039] In this embodiment, both the sliding groove 23 and the sliding block 18 are T-shaped, and the sliding groove 23 fits into the sliding block 18. The mold box 13 can slide into the sliding groove 23 of the multiple fixing frames 22 through the sliding block 18, which allows the device to automatically replace the mold box 13 without manual operation.

[0040] In this embodiment, the support frame 3 is L-shaped, and a rotating groove is provided on the top of the support frame 3. The turntable 4 is rotatably installed inside the rotating groove, and the support frame 3 and the turntable 4 are located on the same straight line. The fact that the support frame 3 and the turntable 4 are located on the same straight line makes the mold box 13 more stable when it moves by the moving pulley 17, and makes it easier and less strenuous for personnel to move and push the mold box 13.

[0041] In this embodiment, a sealing ring is fixedly installed on one side of the sealing plate 15, and the sealing plate 15 is in contact with the hot pressing sintering machine body 5; the sealing ring can prevent the hot gas generated during the hot pressing sintering process from leaking after the mold box 13 enters the hot pressing sintering machine body 5.

[0042] The specific operation is as follows: the diamond cutter head body 14, which is required during the use of the hot pressing sintering machine body 5, is placed inside the mold box 13.

The control motor 28 drives the drive shaft 29 and the turntable 4 to rotate, which can control the electric telescopic rod 25. The angle of the electric telescopic rod 25 is adjusted so that its movement direction is towards the quick-change slot 21 on one side of the hot press sintering machine body 5. The electric telescopic rod 25 is controlled to move the mold box 13, and the sliding block 18 on the top of the mold box 13 slides into the fixing frame 22 inside the quick-change slot 21. The fixing frame 22 has a sliding groove 23 on one side, which fits with the sliding block 18, making the mold box 13 easier and faster to install. In addition, a sealing plate 15 is provided on one side of the mold box 13, which can effectively prevent hot gas leakage from the hot press sintering machine body 5 during use. In the case where the mold box 13 is being processed inside the hot pressing sintering machine body 5, the operator can place multiple mold boxes 13 to be processed and diamond cutter head bodies 14 on the support frame 3, and control the electric telescopic rod 25 to drive the pulling block 27 to pull the locking block 26 above the mold box 13, and pull it into the fixed frame 22 on one side of the electric slider 12, controlling the electric slider 12 to move above the electric slide rail 11. Multiple fixed frames 22 are installed on the mounting frame 6, allowing the electric telescopic rod 25 to push the mold box 13 into different fixed frames 22. This allows for the temporary storage of multiple mold boxes 13. After the mold box 13 inside the hot press sintering machine body 5 is processed, it can be removed and moved to the support frame 3 for placement. Other mold boxes 13 on the mounting frame 6 can be controlled by the electric telescopic rod 25 and the pulling block 27, allowing other mold boxes 13 to quickly enter the interior of the hot press sintering machine body 5. During this process, personnel only need to place and retrieve the mold box 13 on the support frame 3 without having to approach the hot press sintering machine body 5, thereby reducing the risk of burns and improving the safety of the staff.
