Multi-cavity sandwich profile integral forming method and system

The invention discloses a method and a system for integrally forming a multi-cavity sandwich profile, relates to the technical field of profile production, and aims to improve the production efficiency and the performance of the profile, butt-joint foam core materials through mortise and tenon joints, and in the pultrusion process, under the action of internal pressure and temperature of a mold cavity of a heating and curing mold, the foam core materials are subjected to extrusion molding, so that the production efficiency and the performance of the profile are improved. The foam core material and the fiber cloth are formed into a whole, the rigidity of the multi-cavity sandwich sectional material is improved in a large range through the use of the foam core material structure, the layering design has more flexible selectivity, the wall thickness of the sectional material and the use amount of the fiber material are effectively reduced, and meanwhile the sound insulation and vibration reduction performance is
