Description

Bicolor injection mould strand tooth mechanism driving device

Technical field

This utility model relates to the technical field of injection mold, particularly a kind of bicolor injection mould strand tooth mechanism driving device.

Background technology

At present, increasing to double-colored injecting products demand on market, double-shot moulding product uses double-shot moulding to shape work Skill is made, and it is the injector using two or more injecting systems that double-shot moulding shapes, by different cultivars or the most homochromy The manufacturing process that the plastics in pool are injected in grinding tool simultaneously or successively.Dual-color forming machine differs primarily in that with common injection machine: 1. there are two injecting systems；2. have and make mould dynamic model or die cavity position realize the mechanism rotated.Due to double-colored forming machine Particularity, the when that its internal use Jiao Ya mechanism carrying out the demoulding to threaded product, will run into what Jiao Ya mechanism drove Difficulty: the Jiao Ya mechanism of general injection machine, is to use hydraulic motor directly to drive, but in dual-color forming machine, mould needs Rotate and carry out biphasic injection, if hydraulic motor and then mould rotates, then the wiring of hydraulic motor also can follow around Circle, produces wiring problem with this, and reduces the stability of whole system, is greatly increased fault rate.

Summary of the invention

This utility model directly drives the wiring problem of the Jiao Ya mechanism of bicolor injection mould for existing hydraulic motor, uses A kind of bicolor injection mould with jaw clutch twists tooth mechanism driving device.

The technical solution adopted in the utility model completes in the following way: a kind of bicolor injection mould Jiao Ya mechanism drives Device, this device is made up of hydraulic motor, half-clutch device one, half-clutch device two, driven shaft, and hydraulic motor is fixed on double-colored On the inner beam of forming machine, the driving shaft of hydraulic motor uses bonded with half-clutch device one, and half-clutch device two is located at double-shot moulding On mould, half-clutch device two uses bonded with driven shaft, and driven shaft drives the work of Jiao Ya mechanism；Half-clutch device one with half from There is tooth on the end face of clutch two, utilize the mutual tabling of tooth on two halves clutch end face or disengage to reach driving shaft and driven shaft Clutch.

In described bicolor injection mould strand tooth mechanism driving device, driving shaft uses flat key to be connected with half-clutch device one.

In described bicolor injection mould strand tooth mechanism driving device, driven shaft uses spline to be connected with half-clutch device two.

In described bicolor injection mould strand tooth mechanism driving device, at driven shaft near one end of key, it is provided with a ladder End face, is provided with spring between the ladder end face and the end face of half-clutch device two of driven shaft, at half-clutch device one and half-clutch device Two combinations are played and are made cushioning effect, make the two combination more smooth and easy, are difficult to break tooth.

During work, after bicolor injection mould is rotated in place, position sensor can send signal, drives hydraulic motor work, Half-clutch device one is ejected chimeric with half-clutch device two, and by the most axially driven shaft transmission moment of torsion, drive Jiao Ya mechanism； After Jiao Ya mechanism completes the demoulding, half-clutch device one can be regained by hydraulic motor, makes half-clutch device one and the disengagement of half-clutch device two, So that bicolor injection mould carries out rotation process.

This use new structure is simple, and degree of stability is high, and is applicable to the Jiao Ya mechanism driving of polychrome, multistation.

Accompanying drawing explanation

Accompanying drawing 1 is the structural representation of this utility model bicolor injection mould strand tooth mechanism driving device.

In fig. 1, wherein:

1 represents hydraulic motor；1a represents driving shaft；2 represent half-clutch device one；3 represent half-clutch device two；3a represents tooth； 4 represent driven shaft；4a represents ladder end face；5 represent spring.

Detailed description of the invention

Below against accompanying drawing, by embodiment, the utility model is described in further detail.

Referring to the drawings 1, a kind of bicolor injection mould strand tooth mechanism driving device, this device is by hydraulic motor 1, half-clutch device one 2, half-clutch device 23, driven shaft 4 form, and hydraulic motor 1 is fixed on the inner beam of dual-color forming machine, hydraulic motor 1 Driving shaft 1a uses flat key to be connected with half-clutch device 1, and half-clutch device 23 is located on bicolor injection mould, half-clutch device two 3 use spline to be connected with driven shaft 4, and driven shaft 4 drives Jiao Ya mechanism to work；Half-clutch device 1 and half-clutch device 23 End face on have tooth 3a, utilize the mutual tabling of tooth 3a on two halves clutch end face or disengage to reach driving shaft 1a with driven The clutch of axle 4；At driven shaft 4 near one end of spline, it is provided with a ladder end face 4a, at the ladder end face 4a of driven shaft And it is provided with spring 5 between the end face of half-clutch device 23, is combined to play with half-clutch device 23 at half-clutch device 1 and buffers Effect, makes the two combination more smooth and easy, is difficult to break tooth 3a.
