INJECTION-MOLDING AND SEPARATING DEVICE OF A PORTABLE MISSILE, CAPABLE OF MINIMIZING AN OCCUPYING AREA AND WEIGHT SINCE THE MISSILE IS INJECTION-MOLDED AND SEPARATED WITHOUT A SEPARATE SEPARATING UNIT

摘要

PURPOSE: An injection-molding and separating device of a portable missile is provided to enable the missile to be triggered even at a narrow space since the length of flame is decreased by multiple nozzles.;CONSTITUTION: An injection-molding and separating device(100) of a portable missile(1) comprises a fixing unit(110), a frame unit(130), and a piston unit(140). The fixing unit is fixed to the rear of the missile by a fastening screw(113). The frame unit comprises inner and outer burning pipes(131,132), a combustion chamber(135), and nozzles(136). An igniter(121) is installed in the inner burning pipe. The combustion chamber is arranged in the space between the inner and outer burning pipes. The nozzles emit combustion gas from the combustion chamber. The piston(141) of the piston unit is relatively moved to the frame unit. For the fastening screw to be broken by the pressure, which is formed by some of the combustion gas, the piston unit supplies external force.;COPYRIGHT KIPO 2011
