Abstract
The utility model relates to a nozzle device of a plastic injection machine, which comprises a nozzle body 1 and an outer sleeve 2; the tail end of the outer sleeve 2 is provided with screw threads, and the diameter on the front end of the outer sleeve 2 engaging with a fixed plate 4 at least coincides with the outer diameter of the threads on the tail end; the outer sleeve 2 can be inserted into a hole corresponding to the fixed plate, and can be screwed with the injection machine head; the front end of the outer sleeve 2 exposed to the fixed plate 4 can be manufactured with a torsion device 21 for conveniently rotating the outer sleeve 2. The nozzle device of the plastic injection machine has the advantages of convenient disassembling and assembling the outer sleeve and the nozzle, time saving, etc.
Description
The utility model relates to a kind of injection machine parts, particularly a kind of injection machine spray nozzle device.
Injection machine spray nozzle device in the routine techniques as shown in Figure 1, comprise mouth body 1, overcoat 2 and step cover 3, mouth body 1 is sleeved in the overcoat 2, its front end exit end exposes, overcoat 2 tail ends connect with the injection machine head thread, and front end then can be bearing on the step cover 3, and step cover 3 step surfaces by its outer axial face are bearing on the fixed head 4, fixed head 4 is the flat boards that the area of plane is relatively large, and it and injection moulding head are affixed.Stop up and when needing cleaning, behind the fixed head 4 of must dismantling earlier, could take out overcoat 2 and mouth body 1 to clean when the space alluvial of injection molding material between mouth body 1 and overcoat 2, like this, the cleaning dismounting is extremely time-consuming and inconvenient.
The purpose of this utility model is to overcome weak point of the prior art, and a kind of cleaning easy accessibility, timesaving injection machine spray nozzle device are provided.
The purpose of this utility model realizes by following approach.
The injection machine spray nozzle device, comprise mouth body and overcoat, the overcoat tail end has screw thread, its structural feature is: the overcoat front end is identical with its tail end major diameter of thread at least with the diameter of fixed head bonding part, overcoat can insert from the corresponding hole of fixed head and connect with the injection machine head thread, and the part manufacturing that the overcoat front end exposes to fixed head has the torsion device of being convenient to rotary sleeve.
Like this, during dismounting,, overcoat and mouth body can be unloaded, and need not dismantle mobile fixed head as long as apply rotating torque turning round the assembling device place, both convenient, simple, save time again, laborsaving.
The purpose of this utility model can also realize by following approach.
The diameter of overcoat front end and fixed head bonding part is greater than its tail end major diameter of thread.
Corresponding interporal lacuna cooperates connection in overcoat front end and the fixed head.
Torsion device or a kind of outer-hexagonal head, or a kind of outer four angle heads, or a kind of inner hexagonal hole, or four jiaos of holes in a kind of, or at least three apertures that distribute along the overcoat front end face.
In sum, the utility model has following advantage compared to existing technology: need not mobile fixed head, be conveniently detachable overcoat and mouth body, save time, laborsaving, and when former type is transformed, only need to change overcoat and get final product, zero, parts except that overcoat all need not to change, so practicality is extremely strong.
Accompanying drawing 1 is the injection machine spray nozzle device structural representation in the routine techniques.
Accompanying drawing 2 is structural representation sketches of injection machine spray nozzle device most preferred embodiment described in the utility model.
Below we carry out more detailed description to the utility model in conjunction with the accompanying drawings.Most preferred embodiment:
With reference to accompanying drawing 2, injection machine spray nozzle device, comprise mouth body 1 and overcoat 2, the diameter of overcoat 2 front ends and fixed head 4 bonding parts is greater than its tail end major diameter of thread, corresponding interporal lacuna cooperates connection on this bonding part of overcoat 2 front ends and the fixed head 4, overcoat 2 tail ends have screw thread, overcoat 2 can insert the corresponding hole from fixed head 4 and connect with the injection machine head thread, and overcoat 2 front end face manufacturings are by a kind of torsion device of being made up of four holes 21.
It is same as the prior art that present embodiment is not stated part.
