EXHAUST DEVICE FOR PLASTICS INJECTION MOLDING MACHINE

摘要

PURPOSE:To prevent gas generating in melting of plastics and lubricant mist, etc. from diffusing into clean room provided with an injection molding machine by a method wherein a collecting hood provided near an injection nozzle is connected with an exhaust duct discharge exhaust. CONSTITUTION:When the plastics injection molding machine 14 is in motion, gas generating in melting of plastics leaks from the end of the injection nozzle 15. The inner part of the outer plate 16 is filled with mist of lubricating oil for lubrication of the operating section of a mold clamper. The gas generating when plastics is melted is collected by the suction section of an exhaust fan from the collective hood 3 to be guided into the exhaust duct 1 and moved to the collective duct 4. The air containing lubricating oil mist is guided into the collective duct 4 and this air that has been mixed with the generating gas there is exhausted from the exhaust port 7 or without passing the collective duct directly outside the clean room after it is purified by a filter provided on the side of the exhaust fan.
