Beschreibung
Zusammenfassung:	A direct injecting device of optical moldings is provided to reduce supply time and to increase productivity by injecting material into a cavity quickly with a supply unit, and to prevent epoxy from being hardened by heating an upper mold and a lower mold slightly. A direct injecting device for optical moldings is composed of an upper mold(3), a lower mold(4) vertically arranged in the upper mold, and a supply unit(5) injecting material into the lower mold quickly by moving laterally before closing the upper mold in the lower mold. The upper mold is placed in the upper part of the lower mold, and the lower mold is moved up to be contacted to the upper mold lifting up after injecting material into the lower mold with the supply unit. Epoxy is molded according to pattern or profile in a cavity(41) or a pressure block(31) by applying pressure to the upper mold and the lower mold.
