Abstract

The invention relates to the technical field of preforming molds, in particular to a frame type segmented hot-pressing preforming mold which comprises single-segment molds which are evenly segmented from the head end to the tail end in the length direction of the mold and are sequentially connected, and each single-segment mold comprises an upper left mold, an upper middle mold, an upper right mold, a lower left mold, a lower middle mold and a lower right mold. Mold cores of the upper left mold, the upper right mold and the lower middle mold are made of substitute wood, heating modules are arranged in the lower left mold, the lower right mold and the upper middle mold respectively, and the mold cores are made of aluminum alloy, so that temperature partition adjustment of the single-section mold is achieved; the large carbon fiber composite material part is formed in a segmented mode, the mold machining difficulty is reduced, different areas of the part are formed, a frame type mold structure is formed, the overall weight of the mold is reduced, the requirement for the maximum mold weight of equipment is met, heating modules are arranged in the different areas for heating, and the mold machining efficiency is improved. Therefore, partition adjustment of the mold temperature is achieved, and the heating uniformity of a workpiece is improved.

Description

technical field [0001] The invention relates to the technical field of preforming moulds, in particular to a frame type segmented hot pressing preforming mould. Background technique [0002] Carbon fiber has many excellent properties, such as high axial strength and modulus, low density, high performance ratio, ultra-high temperature resistance in non-oxidizing environment, and good fatigue resistance, so it is widely used in the aviation field, and large carbon fiber composite parts are long. About 8000mm, the requirements for dimensional tolerance and geometric tolerance are relatively high. [0003] The pre-forming of the part generally adopts the pre-forming process of the hot-pressing mold. The hot-pressing pre-forming process mold needs to be heated to 80 ° C. Because the size and length of the mold of the part is large, the thermal expansion of the mold material causes the size of the mold to change greatly. The dimensional tolerances and geometrical tolerances of th...
