[0035] In summary, the synchronous sintering device for multi-layer molds of diamond cutting heads provided by this utility model first clamps the cold-pressed diamond cutting head inside the positioning frame 31 by the extrusion block 32. By rotating the hexagonal sleeve 35, the extrusion block 32 can be moved closer to the center of the positioning frame 31 to clamp the diamond cutting head. Then, multiple sets of mold components 3 are placed between two adjacent sets of positioning components 5, between the bottom set of positioning components 5 and the bottom plate 2, and between the top set of positioning components 5 and the top plate 7. After the mold components 3 with diamond drill bits are placed, the threaded block 11 can be moved downward along the screw 9 by rotating the threaded block 11. At this time, the threaded block 11 can press down the side plate 10, and the top plate 7 moves downward. At this time, the positioning frame 31 can be clamped and fixed by the support block 52 and trapezoidal block 53 on each set of positioning components 5. At the same time, the device has low heat radiation resistance, which is conducive to uniform heating of the diamond cutting head.

[0036] By pressing down on the lever 135, the limiting block 134 can move downward synchronously. When the limiting block 134 moves into the housing 131, the slider 121 can slide forward along the guide rod 122. At this time, the base plate 2 can be pulled forward, which facilitates the installation and removal of the mold assembly 3. After the mold assembly 3 is installed or removed, the base plate 2 is pushed back into the sintering furnace body 1. When the base plate 2 moves to the deepest part of the sintering furnace body 1, the limiting block 134 can be reset upward by the elastic force of the spring 136. At this time, the limiting block 134 can block the base plate 2. At the same time, the elastic force of the spring 124 can make the base plate 2 and the limiting block 134 fit tightly. This structure facilitates the installation of the mold assembly 3.
