Abstract:
The present disclosure describes systems and methods for creating sharp features within a mold. For example, three or more mold plates may be provided to create a single mold assembly. Each mold plate includes one or more mold cavities, each having one or more surfaces. The provided mold plates may be assembled to form the mold assembly having a combined mold cavity between adjacent mold cavities of the mold plates. Although none of the individual mold cavities of the mold plates include sharp features, when the mold assembly is assembled, a combined mold cavity will include sharp transitions (e.g., angles of less than 180 degrees, right angles, angles of less than 90 degrees, and so forth) between adjacent surfaces of the mold cavities. In certain embodiments, sets of mold plates may be re-aligned to create varying mold cavity geometries. In addition, in certain embodiments, a mold pin may be inserted into an inner volume of a mold plate to both create additional sharp transitions between adjacent surfaces.
