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 porous graphite sleeve combination device of a batch sintering and painting die. The combined device comprises a graphite sleeve and clamps, wherein the graphite sleeve is in an integral shape, and a plurality of graphite holes penetrating through the body are formed in the graphite sleeve from top to bottom, and the central axes of the plurality of graphite holes are parallel to each other; and the number of the clamps is matched with that of the graphite holes, and the clamps are used for clamping and fixing to-be-sintered bodies in the graphite holes. Due to the fact that the graphite sleeve is in the shape of a whole, in the sintering process, the temperature of each part of the graphite sleeve is uniform and consistent, the sintering temperature of each sintering body is consistent, the hardness and the strength of the sintered body in the same batch are guaranteed, and the quality problem caused by sintering of a single graphite die sleeve in the priorart is solved.

Description

technical field [0001] The invention belongs to the technical field of paint moulds, in particular to a porous graphite sleeve assembly device for batch sintering paint moulds. 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 sintered bo...
