Mold and device capable of producing honeycomb core material continuously, and using method of mold

The invention belongs to the technical field of composite material manufacturing and in particular relates to a mold and a device capable of producing a honeycomb core material continuously, and a using method of the mold. The mold capable of producing the honeycomb core material continuously comprises a front mold and a rear mold which are matched mutually; the rear mold comprises a plurality of regular hexagonal prisms arranged in a staggered manner, and a gap for forming the thickness of the side wall of the honeycomb core material is formed between the side walls of the two adjacent regular hexagonal prisms; and after the front mold and the rear mold are matched, a certain gap is formed between the side wall of each regular hexagonal prism of the rear mold and the front mold, and each gap is used for forming the thickness of the side wall of the honeycomb core material. According to the mold, a honeycomb structure can extend in any direction, and the honeycomb core material can be produced continuously due to application of movable structures of the rear mold and the front mold; and particularly, a long fiber material and thermoplastic resin are used as materials and can be used for preparing the honeycomb core material reinforced by Z-directional continuous fibers.
