Abstract
The utility model discloses a hot nozzle of a hot runner mould. The hot nozzle comprises a nozzle body, a hot mouth, a heating ring, a heat-insulating sleeve and an elastic check ring, wherein the hot mouth is arranged at the front end of the nozzle body; a groove is formed on the outer side of the nozzle body; the heating ring is embedded in the groove; the heat-insulating sleeve is arranged outside the nozzle body; and the elastic check ring is arranged at the bottom of the nozzle body. The hot nozzle is of a simple structure, the heating ring is embedded in the groove of the nozzle body, so the groove and the heating ring are tightly combined and are not easy to loose, the heat transfer efficiency is greatly improved, the interior of the nozzle body is uniformly heated, a rubber material in the nozzle body is ensured to be in a molten state of certain temperature, the requirements on utilization are met, and the service life is long.
Description
Technical field
The utility model relates to the hot runner mould technical field, is specifically related to a kind of hot mouth of hot runner mould.
Background technology
Hot runner mould is to utilize heater to make the noncondensing all the time mould of melt in the runner.Hot mouth is one of critical component of hot runner mould, the Products Quality that the quality of hot mouth performance directly affects.Hot mouth requires not only to guarantee that sizing material gets into the die cavity of hot runner mould smoothly when working; Must guarantee that also sizing material is in the molten condition under the uniform temperature in the hot mouth; Therefore most hot mouth all can add heater in the periphery, particularly for the higher melten gel of some temperature, and more should be like this.Many traditional hot mouth structures are as shown in Figure 1,, the heating circle is spirally wound on the outer surface of mouth body, adds hot nozzle body, thereby guarantees melten gel temperature in the mouth body.There is following defective in such structure: one, owing to generate heat circle on the mouth external surface; Make the heating circle originally exist gap and mouth body and extraneous contact area bigger with mouth, heating circle thermal loss is big, and heat utilization ratio is low; This will be difficult to guarantee the melten gel temperature for some high temperature material; Two, will generate heat circle directly on the mouth body, be easy to cause the mouth body zones of different inequality of being heated, thereby possibly cause the melten gel variations in temperature and change, endanger bigger; Three, the heating circle of this kind structure takes place easily looseningly, and after long-time the use, spiral heating circle spring takes place easily shrinks, and finally also can cause the hot mouth inequality of being heated.
The utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of hot mouth of hot runner mould simple in structure is provided, and its heat utilization ratio is high, be heated evenly, can guarantee that the sizing material in it is in the molten condition under the uniform temperature.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
A kind of hot mouth of hot runner mould comprises the mouth body, and the external side of said mouth is provided with groove, and the hot mouth of this hot runner mould also comprises the heating circle that embeds in the said groove.Heating circle embeds in the groove, and three faces of heating circle are closely contacted with the mouth body, having improved the contact area of heating circle with the mouth body greatly, and both closely contact, the gap is little, the heat that having improved the heating circle greatly is passed to the efficient of mouth body, heat utilization ratio height.In addition, heating circle embeds in the groove of mouth body, with the mouth body combine more tight, be difficult for because of use for a long time, heating produces fatigue and becomes flexible long service life.
Preferably, said groove is shape in the shape of a spiral, and the heating circle embeds in the helical groove and is closely linked with the mouth body.
Preferably; For further reducing the loss that the heat that is produced is enclosed in heating; The utility model also comprises the collet of the outside that is installed in the mouth body; The heating circle is integrated with the mouth body and is placed in the collet, and the heat that makes the heating circle produced is difficult for being diffused into the collet outside, has improved the utilization rate of heat.
Preferably, do not become flexible diametrically for further guaranteeing the mouth body, guarantee the performance of hot mouth, improve service life, the utility model is also at the installation circlip of the bottom of mouth body.
Preferably, mouth body and heat are chewed interference fit.
The beneficial effect of the utility model is: the heating circle embeds on the groove of mouth body itself; Both are combined closely is difficult for becoming flexible; Simultaneously also improved heat transference efficiency greatly and the inside of mouth body is heated evenly; Guarantee that the inner sizing material of mouth body is in the molten condition of uniform temperature, satisfies user demand and long service life.
Description of drawings
Fig. 1 is the described prior art constructions sketch map of background technology;
Fig. 2 is the structural representation of a kind of embodiment of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and practical implementation example the hot mouth of a kind of hot runner mould of the utility model is done further explain.
Please with reference to Fig. 2, the hot mouth of the hot runner mould of the utility model comprises that mouth body 1 and the heat that is installed in mouth body 1 front end chews 2.The outside of mouth body 1 is provided with groove (figure does not show).Groove is shape in the shape of a spiral.One heating circle 3 embeds in the groove, and formula is twined mouth body 1 in the shape of a spiral.Because heating circle 3 is in the groove that embeds on the mouth body 1, is closely as one with mouth body 1, the heat that makes heating circle 3 produced can pass to mouth body 1 efficiently, simultaneously mouth body inside is heated evenly.For further reducing the loss of the heat that heating circle 3 produced, the utility model is a collet 4 on the outer cover of mouth body 1 also.For guaranteeing that mouth body 1 does not become flexible diametrically, guarantee the performance of hot mouth, improve service life, the utility model is also installed circlip 5 in the bottom of mouth body 1.Be to guarantee that mouth body 1 and heat chews the efficient that the heat between 2 transmits, guarantee that heat chews the uniformity of the temperature of the runner in 2, mouth body 1 and heat are chewed 2 interference fit, that is: the external diameter chewed less than heat of the internal diameter of mouth body.
Above-mentioned embodiment is merely the preferred implementation of the utility model; Can not limit the protection domain of the utility model with this, the variation of any unsubstantiality that those skilled in the art is done on the basis of the utility model and replacement all belong to the utility model scope required for protection.
Claims (5)
