Abstract
An energy saving device for accelerated pressurization in an injection molding machine includes a mold needing vapor and cooled water or oil in an injection molding process. The cooled water or oil is provided by a pump, followed by connecting to the mold through a water or oil supply pipeline. The interior of the accelerated pressurization energy saving pipe is a through hole. Three or more spiral grooves are provided on the inner peripheral surface of the through hole and having an angle rotated in a front direction, with the lateral direction of each spiral groove having an inclined angle. The vapor or water or oil enforces angle rotation and inclined angle accelerated pressurization.
