Abstract

The utility model provides a carbon fiber special-shaped part forming die which comprises an upper die and a lower die, and a cavity matched with the outline of a special-shaped part is formed when the upper die and the lower die are closed. An inclined guide structure is arranged on the edge of the closed surface of the upper die and the lower die, and the inclined angle of the inclined guide structure is 10-30 degrees; a heating system is embedded in the surface of a cavity of the lower mold and comprises heating holes distributed along the contour of the cavity at equal intervals and a heat conduction pipe penetrating through the side wall of the mold; the top of the upper die is provided with a material injection port communicated with the cavity, and the bottom of the lower die is provided with at least two rapid exhaust grooves which are symmetrically distributed. According to the carbon fiber special-shaped part forming die, the upper die and the lower die are accurately positioned, the structural precision is ensured, the heating holes are distributed at equal intervals to be matched with the side wall of the heat conduction pipe for heat dissipation, the temperature difference of the surface of the cavity is small, and the resin curing uniformity is improved; and the exhaust grooves are formed, so that the bubble residual rate is reduced, the product density is improved, and the product precision is improved.
