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.
