Described herein is a mold for making units of a dome structure, comprising: a first mold piece(10), a second mold piece(20), a third mold piece(30); the third mold piece(30) is configured to be sandwiched between and assembled with the first and second mold pieces; wherein an assembly of the first mold piece(10), the second mold piece(20), and the third mold piece(30) is configured to form a mold cavity(300); wherein the third mold piece(30) comprises a plurality of sidewall plates; wherein the plurality of sidewall plates are perpendicular to a same spherical surface when the third mold piece(30) is assembled with the first and second mold pieces. Described herein is also a method of using the mold, and the method comprises: assembling the plurality of sidewall plates to form the third mold piece(30); assembling the second mold piece(20) and the third mold piece(30); assembling the first mold piece(10) with the second mold piece(20) and the third mold piece(30) to form the mold cavity(300) of a first-level mold; injecting a molding material into the mold cavity(300); forming a unit of a first-level dome structure by allowing the molding material to form into shape; opening the first-level mold; extracting the unit of the first-level dome structure. |
