The invention provides a 4D printing intelligent core mold, a preparation method and a forming method of a composite material component, and belongs to the technical field of intelligent molds. The intelligent core mold is prepared from a shape memory polymer material through 4D printing and comprises at least one deformation area and two variable stiffness areas which are alternately arranged; each deformation area is located between every two adjacent variable stiffness areas; and a wrinkle group is integrally formed in the deformation area. The intelligent core mold provided by the invention can be used for forming a multi-dimensional non-coaxial complex structure composite material component, is high in forming precision and easy to demold, and solves the problems of low dimensional precision and difficulty in demolding when an existing intelligent core mold is used for forming a non-coaxial large-angle bending complex structure component. 本发明提供了一种4D打印智能芯模及制备方法、复合材料构件的成型方法，属于智能模具技术领域，该智能芯模由形状记忆聚合物材料经4D打印制
