The invention belongs to the technical field of paper matrix molding and particularly relates to heat protection self-alignment fine-tuning paper matrix molding equipment. The heat protection self-alignment fine-tuning paper matrix molding equipment comprises an upper mold and a lower mold, wherein the upper mold, as well as the lower mold, is sequentially connected with a heating plate, a heat conduction plate and a baseplate; each heat conduction plate and the corresponding baseplate are mutually connected through two or more heat protection elastic supports and positioning beams; each heat protection elastic support sequentially comprises a heat protection column component, a spring component and a mounting base from the inside out; the heat protection column components are arranged in the corresponding mounting bases; the mounting bases are connected with the baseplate; each heat protection column component is formed by sequential pressure assembly of one or three or more heat protection columns, and each heat protection column is provided with an upper-end connecting plate, a side-edge connecting plate and a lower-end connecting plate; and the upper mold is provided with upper mold positioning blocks in crossed distribution, and the lower mold is provided with lower mold positioning grooves in crossed distribution. The heat protection self-alignment fine-tuning paper matrix molding equipment has the self-alignment fine-tuning function and a remarkable heat protection effect, and is high in load-carrying property and obvious in technical benefit.
