Abstract:
1. An energy saving device for accelerated pressurization in an injection molding machine, comprising: an injection molding machine provided with a mold, a boiler, a vapor supply pipeline, and a backflow pipeline, with said boiler generating vapor, with said vapor supply pipeline connecting said boiler and said mold, with the vapor supplied to said mold through said vapor supply pipeline, with said backflow pipeline connecting said mold to said boiler; wherein an accelerated pressurization energy saving pipe is concatenated on said vapor supply pipeline or said backflow pipeline, with an interior of said accelerated pressurization energy saving pipe being a through hole, with three or more spiral grooves provided on an inner peripheral surface of said through hole, with said spiral grooves having an angle rotated in a front direction, with a lateral direction of each of said spiral grooves having an inclined angle, with the vapor enforcing angle rotation and inclined angle providing quick thermal transfer performance.
