2. Descriptions of Related Art
As age advances, a lot of products are made of plastics. However, injection molding machines are utilized to a large proportion for plastic molding techniques. For conventional injection molding machines, plastics are melted into fluids in a boiling manner, followed by pushing fluid plastics with high pressure. Moreover, the front end of a conventional injection molding machine is provided with a mold, a cavity of which is filled with fluid plastics under high pressure, followed by cooling for the product to be formed. Nevertheless, the mold itself needs a considerable temperature in the process that injects glue solution into the mold. Solidification due to cooling is not allowed before the glue solution is on position. The blocking for evacuated glue solution would result in unsuccessful molding. Furthermore, once all glue solution is on position, cooling to forming has to be performed rapidly. Otherwise, prolonged time would reduce the efficiency of processing substantially for the production cost to be increased considerably and adversely impact on market competitiveness.
Wherein, the thermal energy of the mold comes from the provision of vapor generated by the boiler, while the cooling of the mold comes from water, oil pressurized by the pump. Because the efficiency of temperature increase or decrease is still low, it is still a high energy consuming machine as for energy usage effectiveness and does not comply with present requirement of energy saving.
It is an objective of the present invention to provide an energy saving device for accelerated pressurization in injection molding machine, which supplies vapor to a old by a boiler, supplies water, oil to the mold by a pump, one or more accelerated pressurization energy saving pipes being concatenated on pipelines mainly supplying vapor or water, oil to the mold or backflow, loopback pipelines, said accelerated pressurization energy saving pipe allowing the vapor or water, oil to generate accelerated pressurization in a natural manner in order for more efficient thermal transfer to achieve the effect of energy saving.
In order to achieve the above and other objectives, the present invention provides an energy saving device for accelerated pressurization in an injection molding machine, comprising: an injection molding machine, said injection molding machine being provided with a mold at a position of a formed product thereof, wherein quick temperature increase by vapor is necessary for the mold in the process of injection molding for melted glue solution to fill cavities smoothly, followed by lowering temperature of the mold quickly in order for solidification of glue solution, wherein, the vapor is generated by boiler heating, followed by being supplied to the mold through a vapor supply pipeline connected thereto, cooling water, oil are provided by a pump, followed by being supplied to the mold through a water, oil pipeline connected thereto, one or more accelerated pressurization energy saving pipes are mainly concatenated on the vapor supply pipeline or water, oil supply pipeline or backflow, loopback pipeline, the interior of said accelerated pressurization energy saving pipe is a through hole, the inner peripheral surface of the through hole is provided with three or more spiral grooves thereon, a R angle is rotated in a front direction of the spiral groove, a lateral direction of the spiral groove is a θ inclined angle, the vapor or water, oil enforces a R angle rotation and a θ inclined angle accelerated pressurization for the spiral groove naturally to output force with the smaller pump and heat by the boiler in order for quicker cooling rate and better thermal transfer performance.
Objectives, features, and advantages of the present invention are hereunder illustrated with specific embodiments in conjunction with the accompanying drawings, in which:
