Multicolor converging injection mechanism

Abstract

The invention provides a multicolor converging injection mechanism, and belongs to the technical field of injection machines. The problem that an existing injection mold head is low in simulation degree is solved. The multicolor converging injection mechanism comprises an assembling block, a first color cylinder, a second color cylinder, a third color cylinder, a connecting pipe, a boss, a first branch pipe, a second branch pipe, a third branch pipe and an injection head. According to the multicolor converging injection mechanism, the central axis of the injection head coincides with the central axis of the third branch pipe, and the central axis of the first branch pipe and the central axis of the second branch pipe both intersect with the central axis of the injection pipe and do not coincide with the central axis of the injection pipe, so that a first pigment and a second pigment are superposed in the injection process; and a third pigment sequentially penetrates through the middlepart of the second pigment and the middle part of the first pigment, and the third pigment is gradually shallower from the second pigment to the first pigment, so that the simulation effect of an injection molding product is improved.

Description

technical field [0001] The invention belongs to the technical field of injection machines and relates to a multi-color converging injection mechanism. Background technique [0002] The current mixed-color injection molding machines mostly use ordinary single-color injection table structure assembly styles, such as right-angle, oblique, and parallel assembly. Complex, many corners, many dead corners, easy to accumulate material, and the plasticized rubber material accumulates and stays at the dead corner of the flow channel for a long time, and the subsequent rubber material cannot push or take away the accumulated rubber material, and produces a vortex like vortex at the corner phenomenon, causing the rubber to stay for a long time under heat, decompose and deteriorate, and turn yellow and black; secondly, most injection molds can only superimpose multiple color materials after injecting the color materials into the cavity of the injection molding machine Injection molding,...

[0002] The current mixed-color injection molding machines mostly use ordinary single-color injection table structure assembly styles, such as right-angle, oblique, and parallel assembly. Complex, many corners, many dead corners, easy to accumulate material, and the plasticized rubber material accumulates and stays at the dead corner of the flow channel for a long time, and the subsequent rubber material cannot push or take away the accumulated rubber material, and produces a vortex like vortex at the corner phenomenon, causing the rubber to stay for a long time under heat, decompose and deteriorate, and turn yellow and black; secondly, most injection molds can only superimpose multiple color materials after injecting the color materials into the cavity of the injection molding machine Injection molding, but the products made of superimposed injection of multiple color materials have a very low degree of simulation, especially the simulated leaves. Through the above-mentioned superimposed injection molding, the roots in the middle of the leaves cannot be simulated, so the degree of simulation of the leaves is reduced.
