DEVICE AND METHOD FOR MOLDING BREEDING FLOAT FOR BREEDING MARINE PRODUCTS THROUGH EXTRUSION BLOW MOLDING

摘要

PURPOSE: A device and a method for molding breeding float for breeding marine products are provided to improve work efficiency and productivity by excluding a process for closing an air injecting port and to prevent the injury on a worker when a buoy is handled. CONSTITUTION: A float molding device(40) is composed of a fixed mold(42) and a feed mold(44). A float is molded by blowing compressed air into the tubular parison placed between the fixed mold and the feed mold. A cavity(46) of a specific depth is symmetrically formed on the face of each mold. An air injecting port(46c) is formed in the edge side of a ring part(46b) of the cavity to fit an air supply tube into the parison corresponding to a float body of the cavity. A guide hole(52) is formed in each mold. A pair of push pins are installed in the guide holes to close the air injecting port upon the discharge of air supply tube by moving linearly.
