The present invention is directed to a resilient and self-locking mold for the prototype molding of an object using a liquid resin, the mold comprising first and second mold portions matable to form a mold of the object, the first mold portion having a first opposing mold face with a cavity therein
The present invention is directed to a resilient and self-locking mold for the prototype molding of an object using a liquid resin, the mold comprising first and second mold portions matable to form a mold of the object, the first mold portion having a first opposing mold face with a cavity therein corresponding to the size and shape of the object to be molded, the second mold portion having a second opposing mold face with a core thereon corresponding to the back of the object to be molded, the opposing mold faces of the first mold portion and the second mold portion, upon mating, defining a void therebetween, the void corresponding in size, shape and thickness, to the object to be molded, the void further having a first orifice for providing resin therein, a second orifice for removing air therefrom, the first mold portion and second mold portion further having opposing members of a resilient interlocking pair on the opposing mold faces, the interlocking pair members when interlocked, providing a resilient and self-locking mold having a void that is resistant to air seepage during molding conditions and upon the void being filled with liquid resin, is capable of holding the first and second mold portions together without external compression until the liquid resin hardens into the object. In addition, the present invention is directed to a method for the rapid prototype molding of a resinous object using the above described resilient and self-locking mold.

[ What is claimed is:] [1.] A reusable, resilient and self-locking mold for the prototype molding of an object, said mold comprising a first resilient mold portion and a second resilient mold portion matable thereto, said first mold portion having a first opposing mold face with a cavity therein corresponding to the shape of said object to be molded, said second mold portion having a second opposing mold face with a core thereon corresponding to the back of said object to be molded, the opposing mold faces of said first mold portion and said second mold portion upon mating, defining a void therebetween, said void corresponding in size and shape to the object to be molded, said void being connected by a first channel to a first orifice for providing resin therein, said void further being associated with a second channel extending to a second orifice on the outer surface of said mold, said second channel and orifice being of sufficient size and shape for removing air from said void, said first mold portion and said second mold portion having opposing members of a resilient interlocking pair on opposing mold faces, respectively, said interlocking pair members circumscribing said core and said cavity on said opposing mold faces, and when interlocked, forming a resilient and self-locking mold having a void that when subjected to reduced pressure, is resistant to air seepage during molding conditions, and when said void is filled with liquid resin, are capable of holding said first and second mold portions of said self-locking mold together, without the application of external force until said liquid resin in said void has hardened into said molded object.
