Injection and plasticizing coaxial micro-injection molding machine

Abstract

The invention discloses a miniature injection molding machine with injection molding and plasticizing in coaxial line design. The miniature injection molding machine comprises an injection molding drive device, a grinding disc plasticizing device, a mold, a mold combination drive device and a clamping plate which are sequentially arranged on pull rods in a penetrating manner. The four pull rods penetrate four holes in each of the injection molding drive device, a base body, a fixed mold plate and the clamping plate in the whole machine, and the injection molding drive device, the base body, the fixed mold plate and the clamping plate are fixedly mounted on the specific positions of the pull rods, the four pull rods penetrate four holes in a movable mold plate, but the movable mold plate can move left and right on the four pull rods for achieving mold opening and mold closing. The miniature injection molding machine is simple and compact in structure, small in occupied space and more smooth in forming action; and melting charge plasticized by the miniature injection molding machine with injection and plasticizing in coaxial line design is directly gathered in a sleeve and is injected through a piston, the melting charge flowing path is short, thermal insulation of the melting charge is facilitated, and the quality of injection molding products can be guaranteed.

Description

technical field [0001] The invention belongs to the technical field of plastic processing equipment, in particular to a miniature injection molding machine with coaxial injection and plasticization. Background technique [0002] Injection molding machines usually consist of plasticizing, injection, mold clamping and other parts. The plasticizing part of the traditional injection molding machine uses the long rod-shaped screw in the rotating barrel to realize the plasticizing action of the plastic, and another set of power system drives the screw to move along the axis to realize the injection action. In order to realize these two actions separately, it is necessary to design complex and bulky driving, transmission and supporting structures in the traditional injection molding machine. Contents of the invention [0003] The purpose of the present invention is to provide a micro-injection molding machine coaxial with injection and plasticization for the lack of traditional ...
