Abstract

The utility model discloses a hot nozzle at a hot runner. The hot nozzle comprises a nozzle body and a nozzle core component, wherein the nozzle core component comprises a heat conductive nozzle core and a wearable nozzle core sleeved in the heat conductive nozzle core; a hole used for mounting of the nozzle core component is formed on the bottom end of the nozzle body; both the nozzle body and the wearable nozzle core are provided with a runner for transmitting glues; and the runner of the nozzle body is communicated with the runner of the wearable nozzle core. As the wearable nozzle core is additionally arranged in the nozzle core component, the hot nozzle has better high temperature and wear resistance without loss of the heat conduction performance of a hot nozzle at the prior art.

Description

A kind of hot runner hot mouth

Technical field

The utility model relates to a kind of hot runner hot mouth.

Background technology

The market of plastic cement products constantly expands, its mechanical strength showing receives much attention, in plastic material, adding glass fibre, to improve the combination properties such as the intensity of plasthetics and case hardness be universal phenomenon, adds fine material, being widely used of electronic product, automotive field, hot runner mould has been proposed to new requirement.Because the sizing material that adds glass fibre is comparatively serious to TOP-TIP wearing and tearing when the injection mo(u)lding, particularly the mouth core in hot runner hot mouth, is generally copper mouth core, and its thermal conductivity is good, wear no resistance, very easily losing efficacy because of excessive wear in cusp position, has increased maintenance cost.The performance that improves hot runner hot mouth is extremely urgent.

Utility model content

In order to overcome the deficiencies in the prior art, the purpose of this utility model is the hot runner hot mouth that high abrasion is provided and has thermal conductive resin.

For addressing the above problem, the technical scheme that the utility model adopts is as follows:

A hot runner hot mouth, comprises mouth body and mouth core assembly, and mouth core assembly comprises heat conduction mouth core and is set in the wear-resisting mouth core of heat conduction mouth in-core; Mouth body bottom is provided with the mouth core hole of fixed installation mouth core assembly; Mouth body and wear-resisting mouth core are equipped with the runner passing through for sizing material, and the runner of mouth body and wear-resisting mouth core interconnects.

The mouth that also comprises parcel heat conduction mouth core.

Mouth is threaded connection the bottom at heat conduction mouth core.

Mouth side is provided with six orientation.

Between mouth and heat conduction mouth core, be provided with avoiding hollow groove.

The top of wear-resisting mouth core is provided with an annular boss, and the upper surface of annular boss is connected to mouth core hole, and heat conduction mouth core top is connected to the lower surface of annular boss, and heat conduction mouth core bottom is threaded connection and is fixed on it mouth.

The side of heat conduction mouth core is provided with flat position.

The top of mouth body is provided with the lifting screw hole for stationary heat mouth.

Compared to existing technology, the beneficial effects of the utility model are: owing to having increased wear-resisting mouth core in mouth core assembly, not losing on present hot mouth heat conductivility basis, make hot mouth reach the effect of better high-temperature wearable.

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

A kind of hot runner mould system that Fig. 1 the utility model provides;

A kind of hot runner hot mouth that Fig. 2 the utility model provides;

A kind of wear-resisting mouth cored structure schematic diagram that Fig. 3 the utility model provides;

A kind of heat conduction mouth cored structure schematic diagram that Fig. 4 the utility model provides.

1, Re Zui; 11, wear-resisting mouth core; 111, annular boss; 12, heat conduction mouth core; 121, flat position; 13, mouth; 14, mouth body; 15, lifting screw hole; 2, main sprue bushing; 3, flow distribution plate.

The specific embodiment

As shown in Figure 1, a kind of hot runner mould system, main sprue bushing 2 is connected with flow distribution plate 3, and hot mouth 1 is closely connected with the runner plastic hole of flow distribution plate 3, guarantees without leaking glue.Melten gel injects from main sprue bushing 2, injects in hot mouth 1 and penetrate at a high speed from the plastic hole of mouth core assembly after runner.

As shown in Figure 2, a kind of hot runner hot mouth 1, comprises mouth body 14 and mouth core assembly, and mouth core assembly comprises heat conduction mouth core 12 and is set in the wear-resisting mouth core 11 in heat conduction mouth core 12; Mouth body 14 bottoms are provided with the hole of fixed installation mouth core assembly; Mouth body 14 and wear-resisting mouth core 11 are equipped with the runner passing through for sizing material, and the runner of mouth body 14 and wear-resisting mouth core 11 interconnects.

Wear-resisting mouth core 11 can be selected steel mouth core, the copper mouth core that heat conduction mouth core 12 can be selected, because steel mouth core is compared hardness with general copper mouth core and wearability is all improved, when the various HTHPs of moulding add fine sizing material, this hot mouth 1 can be resisted its wearing and tearing, and the life-span is extended.

Hot mouth 1 also comprises the mouth 13 of parcel heat conduction mouth core 12.Mouth 13 has adopted the good material of thermal insulation, has avoided amount of heat to be passed to die.

Mouth 13 is threaded connection the bottom at heat conduction mouth core 12.Mouth 13 sides are provided with six orientation.The mode being threaded connection, is more convenient for installation and removal.

Between mouth 13 and heat conduction mouth core 12, be provided with avoiding hollow groove.Avoiding hollow groove has reduced the contact area of mouth 13 with heat conduction mouth core 12, has reduced the thermal loss of heat conduction mouth core 12.

As shown in Figure 4, the top of wear-resisting mouth core 11 is provided with an annular boss 111, and the upper surface of annular boss 111 is connected to mouth core hole, and heat conduction mouth core 12 tops are connected to the lower surface of annular boss 111, and heat conduction mouth 1 core bottom is fixed by screws on mouth body 14.

During assembling, heat conduction mouth 1 core withstands wear-resisting mouth core 11, and heat conduction mouth core 12 is threaded connection and is fixed on mouth body 14, and assembling is simple, fixing reliable;

As shown in Figure 3, the side of heat conduction mouth core 12 is provided with flat position 121.

The top of mouth body 14 is provided with the lifting screw hole 15 for stationary heat mouth 1.Make the easy accessibility of whole hot runner hot mouth 1.

Owing to having increased wear-resisting mouth core 11 in mouth core assembly, not losing on present hot mouth 1 heat conductivility basis, make hot mouth 1 reach the effect of better high-temperature wearable.

Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
