Problems solved by technology

Due to the lack of contact between the graphite mold sets of this sintered structure, a single graphite mold set will have a large temperature difference during the sintering process, resulting in some of the sintered bodies in the 8 graphite mold sets having lower than normal hardness, and some If the hardness is higher than normal, the density of the sintered body is unbalanced, and the strength of the sintered body cannot be guaranteed, thus leaving a quality hazard for the painted mold.

Abstract

The invention relates to a preparation technology of a synthetic diamond sintered bodies. The preparation technology comprises the following steps: firstly, loading and fixing graphite pad rods into aplurality of graphite holes of a graphite sleeve respectively, and loading bottom sintering powder into the graphite holes; pressing polycrystalline mould cores into the bottom sintering powder by positioning rods, and loading surface sintering powder into the graphite holes, wherein the bottom sintering powder, the polycrystalline mould cores and the surface sintering powder jointly form bodiesto be sintered; putting graphite pressing rods into the graphite holes to cover the upper part of the surface sintering powder by the graphite pressing rods; placing a combination of the graphite sleeve, the graphite pad rods and the graphite pressing rods on a graphite sintering machine, and sintering; taking finished sintered bodies in the graphite holes out of the graphite sleeve to obtain synthetic polycrystalline diamond sintered bodies. By the preparation technology, the purpose of sintering painted moulds in batches can be achieved, the sintering temperatures of all the sintered bodiesare consistent and uniform, and the hardness and the strength of the same batch of sintered bodies are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of preparing painted molds, and in particular relates to a preparation process of an artificial diamond sintered body. Background technique [0002] In the prior art, when processing and preparing polycrystalline paint moulds, several individual graphite mold sets (usually 8 graphite mold sets as a batch) equipped with the body to be sintered are placed together on the sintering positioning chassis for sintering, each There is no contact between individual graphite mold sets, and after sintering, the body to be sintered in the graphite mold set becomes a sintered body. Due to the lack of contact between the graphite molds of this sintered structure, a single graphite mold will have a large temperature difference during the sintering process, resulting in some of the sintered bodies in the 8 graphite molds having lower than normal hardness, and some If the hardness is higher than normal, the density of the s...
