When pressure is applied, the six sides of the synthetic block are squeezed separately by six top hammers.

[0003] At present, the shapes and sizes of the six top hammers of the six-sided top press are usually the same. Specifically, the top hammer is a cone as a whole, and the top of the cone is a square hammer face. During production, the hammer faces of the six top hammers form a cubic pressure chamber, and the combined cavity is an outer square and inner cylindrical cavity. The six faces of the combined cavity are respectively connected to the hammer faces of the six top hammers, and the internal cylindrical cavity of the combined cavity is used to place the heating component, the shielding component, and the disc-shaped or cylindrical sample.

[0004] When the above-mentioned six-sided top press is used to produce disc-shaped products, especially when producing large-diameter (diameter > 50mm) products, the synthesized products are prone to square shapes and fail to meet production requirements; in addition, the cube pressure cavity does not effectively utilize the effective volume it encloses and limits the diameter of the product; furthermore, when the square hammer face encloses the cube pressure cavity, the sharp edges of the hammer face are in the stress concentration area after pressurization, which is easily damaged and causes failure.
