NOVELTY - The utility model claims a three-dimensional graphene block casting mould, comprising a mould shell and silica gel, the mould shell is provided with a locating groove, the silica gel membrane fixed in said locating groove. the inside of the silica gel film is of hollow type cavity, the cavity shape of the graphene block have the same three-dimensional modelling, casting method to cast mold of the three-dimensional graphene blocks traditional part forming technology are combined with the modern freeze drying, graphene oxide aqueous solution; three-dimensional graphene blocks pouring the silica gel membrane of the type cavity, by cooling and freezing forming, then freezing and drying and heating reduction so as to prepare out three-dimensional graphene piece three-dimensional graphene block material or various shapes, simple manufacturing, convenient and can be applied to industrial production, providing support through the mold shell, casting out of corresponding shape by the shape of the cavity, through silica gel characteristics of the silica gel film can make three-dimensional graphene blocks taken out successfully, avoid adhesion.
