Abstract
A dismountable mechanical core (1) includes a counterform (2) attached to a central mandrel (3,8), the counterform components being able to be handled remotely and with complete safety. These components of the counterform are connected and attached to the central mandrel (3,8) by rod anchoring devices (6). The process of assembly and disassembly of the core is also described. This dismountable mechanical core is used for the molding of the cavity inside the charge of solid rocket fuel.
