ABSTRACT:
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.
