The hot-runner device of a kind of automatic calibration designed by this object, comprises the flow distribution plate and reducing bushing that are equipped with injection nozzle, and injection nozzle is communicated with the sprue in flow distribution plate, and the middle through hole of reducing bushing is communicated with the runner of sprue branch; It is characterized in that: between flow distribution plate and reducing bushing, be provided with transition piece; Transition piece is provided with transition sphere, expanding with heat and contract with cold according to flow distribution plate, automatic calibration, makes transition piece fit in the sphere of flow distribution plate and the setting of reducing bushing correspondence all the time, preventing from cementing leakage.
Transition piece is logical in being to be arranged, and middle through hole mates with runner, and top and bottom are provided with transition sphere.
Be provided with pad between transition piece and flow distribution plate, pad embeds in flow distribution plate, and is provided with the sphere mated with transition piece; Reducing bushing top is provided with the sphere mated with transition piece.
Time idle, transition piece tilts to have angle b relative to runner; During work, transition piece automatic calibration, makes the axis of the middle through hole of runner, transition piece and the middle through hole of reducing bushing overlap mutually, is formed and mates passage closely.
The angle of inclination b of transition piece is that the changing value expanded with heat and contract with cold according to flow distribution plate calculates.
Transition piece is at least in annular, and top and bottom are raised with sphere outward, have planar annular outside sphere, limited location effect.
The utility model can the transition piece of automatic calibration by arranging between flow distribution plate and reducing bushing, effective preventing from cementing leakage.When being subject to gun barrel impulsive force, bridging flow distribution plate can produce distortion, owing to there being the transition of transition piece between bridging flow distribution plate and reducing bushing, the center of circle of its transition sphere meeting automatic calibration two circles, ensure that two faces are close together, aggregated(particle) structure is just fitted before not having thermal expansion, is also at fit-state always, can not produces leakage glue after waiting expansion to put in place.It has simple and reasonable, that dependable performance, good airproof performance, cost are low feature.

Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described.
First embodiment
See Fig. 3, Fig. 4, the hot-runner device of this automatic calibration, comprise the flow distribution plate 3 and reducing bushing 5 that are equipped with injection nozzle 1, injection nozzle 1 is communicated with the sprue in flow distribution plate 3, and the middle through hole of reducing bushing 5 is communicated with the runner of sprue branch; Transition piece 4 is provided with between flow distribution plate 3 and reducing bushing 5; Transition piece 4 is provided with transition sphere, according to expanding with heat and contract with cold of flow distribution plate 3, automatic calibration, makes transition piece 4 fit in the sphere of flow distribution plate 3 and the setting of reducing bushing 5 correspondence all the time, preventing from cementing leakage.
Specifically, see Fig. 5-Fig. 7, transition piece 4 is logical in being to be arranged, and middle through hole mates with runner, and top and bottom are provided with transition sphere.Be provided with pad 3.1 between transition piece 4 and flow distribution plate 3, pad 3.1 embeds in flow distribution plate 3, and is provided with the sphere mated with transition piece 4; Reducing bushing 5 top is provided with the sphere mated with transition piece 4.It can thus be appreciated that transition piece 4 can in the spaced winding central movable of flow distribution plate 3 with reducing bushing 5.
Time idle, flow distribution plate 3 is not by External Force Acting, and now, transition piece 4 tilts to have angle b relative to runner; During work, hot glue enters flow distribution plate 3 through injection nozzle 1, flow distribution plate 3 expanded by heating, and produce the change toward extension, meanwhile, gun barrel produces impulsive force c to flow distribution plate 3, and flow distribution plate 3 receives again reaction force d.When at least two active forces and thermal expansion change, flow distribution plate 3 acts on transition piece 4, under the guide effect of transition sphere, transition piece 4 is around center rotating, realize automatic calibration effect, the axis of the middle through hole of runner, transition piece 4 and the middle through hole of reducing bushing 5 is finally overlapped mutually, and inner formation mates passage closely.Transition piece 4 is fitted flow distribution plate 3 and reducing bushing 5 all the time.Wherein, the angle of inclination b of transition piece 4 is that the changing value expanded with heat and contract with cold according to flow distribution plate 3 calculates, and the maximum temperature that flow distribution plate 3 heats up is 285 DEG C, now, the swell value of flow distribution plate 3 is maximum, and amplitude of variation is maximum, can determine gradient b by relevant calculating.
Transition piece 4 is specially annular, and top and bottom are raised with transition sphere outward, and the centre of sphere all drops on axis, has planar annular 4.1 outside sphere, limited location effect, prevents transition piece 4 transition activity, produces skew.
Above-mentioned is preferred version of the present utility model, and those of ordinary skill in the art, to its simple modification or transformation, all drop within protection domain of the present utility model.
