Abstract

The invention discloses a plasticizing and injection molding device. A power part of the plasticizing and injection molding device includes a plasticizing servo motor, a speed reducer I, an injection servo motor, a speed reducer II and ball screws; the plasticizing servo motor is mounted on the speed reducer I; an output end of the plasticizing servo motor is fixedly connected with an input end of the speed reducer I; the speed reducer I is mounted on a back injection molding base of the plasticizing and injection molding device; an output end of the speed reducer I is connected with a plasticizing screw rod; one injection servo motor is fixed on the back injection molding base; the back injection molding base performs a linear reciprocating motion on a front injection molding base through two ball screws; and the two ball screws are symmetrically distributed corresponding to the center line of a screw rod. The plasticizing and injection molding device increases the power transfer quantity through optimizing an internal transmission structure to generate higher injection pressure for extruding and melting raw materials on the screw rod so as to realize the production of equipment suitable for high plasticizing quantity with low cost.

Description

technical field [0001] The invention relates to a plasticizing injection molding device for producing plastic bottles. Background technique [0002] The production process of plastic bottles starts with raw materials, which are solid particles, which are injected into molds after being heated and melted, and finally shaped. The melting process of raw materials is completed in the plasticizing injection molding device, which is equipped with heating components and conveying components, wherein the conveying components mainly refer to the power components for the rotation and translation of the screw and the driving screw. The power components were first powered by hydraulic motors, and later changed to hydraulic motors and servo motors to provide power together. However, the existing structural defects and the resulting use defects have seriously restricted the technological progress of injection molding equipment. In the prior art, a plasticizing and injection molding devic...
