Injection molding machine mixed color injection platform and injection molding machine

Abstract

The invention discloses a color-mixing injection platform for an injection molding machine and an injection molding machine. The color-mixing injection platform includes an injection platform base, a sliding bottom plate, a main injection platform mechanism, an auxiliary injection platform mechanism, a moving oil cylinder mechanism, a flange connection body, a color mixing mechanism and Nozzle, the sliding bottom plate is slidably connected to the base of the shooting platform, the main shooting platform mechanism and the auxiliary shooting platform mechanism are fixed on the sliding bottom plate, and the discharge ends are respectively connected to the flange connection body, and the main shooting platform mechanism and The included angle on the horizontal projection of the sub-shooting platform mechanism is less than 90 degrees; the moving oil cylinder mechanism is used to drive the sliding bottom plate to slide back and forth along the base of the shooting platform, the color mixing mechanism is arranged in the flange connection body, and the main shooting platform mechanism and The discharge end of the sub-injector mechanism is connected to the feed end of the color mixing mechanism, and the nozzle is connected to the discharge end of the color mixing mechanism; the color mixing injection mechanism is compact, and the distance of material flow is short, which can effectively avoid material Changes in traits.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment, in particular to an injection molding machine mixing color injection platform and an injection molding machine. Background technique [0002] Most of the existing mixed two-color injection molding machines are parallel double-injection units, and the machine occupies a large area and the structure is not compact enough. In addition, the mixed-color injection molding machine with parallel double-shot platform also has the problem of too long flow path, that is, the distance from the molten plastic leaving the barrel, through the flow path to the nozzle, and finally injected from the nozzle is too long, which is not conducive to accurate Control injection volume. In addition, if the material stays in the flow channel for too long, it may also change its properties. [0003] It can be seen that the prior art still needs to be improved and enhanced.

Problems solved by technology

[0002] Most of the existing mixed two-color injection molding machines are parallel double-injection table mechanisms, and the machine occupies a large area and the structure is not compact enough.

In addition, the mixed-color injection molding machine with parallel double-shot platform also has the problem of too long flow path, that is, the distance from the molten plastic leaving the barrel, through the flow path to the nozzle, and finally injected from the nozzle is too long, which is not conducive to accurate Control injection volume

In addition, if the material stays in the flow channel for too long, it may also change its properties
