Apparatus and method for producing After Cone Fin for Helicopter

摘要

The apparatus and method for manufacturing an after-cone pin for a helicopter of the present invention can produce an after-cone pin for a helicopter having an accurate outer shape and high durability by injecting high-temperature and high-pressure air from the inside. In particular, the apparatus and method for manufacturing an after-cone pin for a helicopter of the present invention lay-up a composite material and harden it by supplying high temperature and high pressure from the inside, and the inner mold maintains its shape, but the first inner mold and the first inner mold are meltable materials. It is made of a second inner mold in the form of a silicon film surrounding the material, and can be maintained so that leakage does not occur from the outside by the outer mold and the reinforcing mold, so that the aftercone pin can be manufactured with high quality (durability) while enhancing manufacturability There is an advantage.
