The invention belongs to the field of cyclic utilizing and recycling of waste high polymer materials, and particularly relates to a method for recycling a wind power blade manufacturing mold through two steps in an all-component mode. In the first step, the waste wind power blade manufacturing mold is cut, and a chemical inert swelling agent is added and swells epoxy resin in the waste wind powerblade manufacturing mold, so that the interface between an aluminum layer and a glass fiber-epoxy resin layer is separated, meanwhile, the interface between the aluminum layer and a copper tube is separated, the copper tube can be directly recycled, and meanwhile, the aluminum layer is recycled; and in the second step, the glass fiber-epoxy resin layer is swollen and fluffy and a catalyst-solventis added, so that the epoxy resin is degraded and soluble, the glass fiber and the epoxy resin are separated, the glass fiber can be directly recycled, and the epoxy resin degradation product is recovered through separation an
