Abstract: Replicas are molded by curing a photo-curable liquid silicone rubber composition to form a transparent mother mold having a cavity corresponding to the outer contour of a master model, casting a photo-curable liquid resin into the mold cavity, and irradiating light to the liquid resin through the mold wall. Replicas can be fabricated by simple steps and within a short time.

Abstract: A form for manufacturing a resin mold has a frame housing a master model corresponding in shape to a product to be molded and having a space defined therein for receiving the ultraviolet-curable resin poured therein around the master model. The frame is made of an ultraviolet-permeable material. When ultraviolet radiation is applied outside of the frame to the frame, the ultraviolet-curable resin in the frame is cured into a resin mold. The resin mold can easily and quickly be manufactured. The resin mold can also reliably be clamped by a clamping jig for producing a high-quality molded product.

Abstract: A molding apparatus includes a molding die having a cavity therein corresponding to the outer shape of a product to be reproduced, and a cast molding device for pouring an ultraviolet curable liquid resin into a cavity of the molding die. An ultraviolet light irradiating device is provided for irradiating ultraviolet light from the outside of the molding die, wherein the ultraviolet curable liquid resin in the interior of the molding die becomes hardened. A transport mechanism is provided for conveying the molding die between the cast molding device and the ultraviolet light irradiating device. Accordingly, an operator is not required to lift and carry the molding die, and the die can be swiftly and easily conveyed by means of the transport mechanism.
