Large composite material mold frame

The utility model discloses a large composite material mold frame which is made of the same material as a mold main body, so that the mold frame and the mold main body are ensured to have the same thermal expansion coefficient, and the mold is prevented from deforming due to the frame; the die frame formed by bonding combination is provided with a plurality of lightening holes and vent holes, so that the weight of the die is reduced, and vertical heat conduction of the die is kept consistent. 本实用新型公开了一种大型复合材料模具框架，本实用新型提供的大型复合材料模具框架，采用与模具主体相同的材质，从而保证模具框架与模具主体具有相同的热膨胀系数，避免模具因框架而变形；通过粘接组合而成的模具框架，设置多个减重孔与通风孔，在减轻模具重量的同时，保证模具上下热传导保持一致。
