る。(Function) During operation of the plastic injection molding machine 14, gas generated when plastic is melted leaks from the tip of the injection nozzle 15. Further, the outer plate 16 is filled with a lubricating oil mist for lubricating the operating parts of the mold clamping device. Due to the suction effect of the exhaust fan, the gas generated when the plastic is melted is collected by the collection hood 3, guided into the exhaust duct 1, and moved to the collecting duct 4. Furthermore, the air containing the lubricating oil mist is guided into the collection duct 4, where it is combined with the generated gas from the exhaust port 7 or directly without going through the collection duct to a filter provided on the exhaust fan side. After being cleaned, it is discharged outside the clean room. The suction amount of generated gas and lubricating oil mist is adjusted by an air volume balance adjustment damper 6 so as to be balanced. Damper 6 is casing 8
It is operated through an inspection port 17 with an opening/closing cover provided in the.

効果を有する。(Effects of the Invention) As described above, the present invention can collect the gas generated when plastic is melted, lubricant mist, etc. and reliably exhaust it to the outside, so that the air in the space where the molding machine is installed, especially in the clean room, can be reduced. Since it is possible to prevent contamination and maintain the cleanliness of the clean room, it is possible to mold ultra-precision products using injection molding machines, and it is also possible to lower the grade of the clean room and significantly reduce equipment costs and operating costs. This has the effect of making it possible.
