[0034] See Figure 1-6 The present invention provides the following technical solution: a method of preparing a polycrystalline diamond tilation model, including the following steps:
[0035] S1: Preparation of a brigadal mold blank, the bristle model is preset in the middle, and a pre-press-shaped one has a ring-shaped internal block spare of an inner hole;
[0036] S2: Assembly of the synthesis block, place the inner assembly block into the loblast assembly block, forming a synthetic block;
[0037] S3: Synthetic block sintering; sintering the synthetic block in a six-sided tip pressure;
[0038]Among them: S2, the synthesis block includes a lobbone stone 1 and a ring cylindrical inner assembly block packaged inside the Yafa stone 1, and the center of the internal assembly is sequentially set internally, and the internal heating tube is sequentially set. 10, in the inner salt tube 9, the inner assembly of the block is sequentially disposed from the inwardly, an outer heating tube...
