Technical background
nullMold injection industry，Hot flow path is applied widely，Wherein in TOP-TIP，The position of most critical is hot mouth，Hot mouth is the direct tool that melted plastic cement is delivered to die cavity，It it is indispensable part in a mould of plastics，Common hot runner mould includes a hot mouth main body、It is positioned at the sharp-tongued of hot mouth body ends，Hot mouth main body and sharp-tongued in be provided with the runner of connection，TOP-TIP is in the course of the work，Body needs heating to be maintained at certain temperature，Therefore electric heating tube is set outside runner，Melted plastic cement is allowed to be extruded by hot mouth after keeping certain temperature，The heat radiation of existing hot mouth structure is many，Thermal conduction effect is bad，Hot nozzle point temperature the most all can lower 40 DEG C than temperature controlling point temperature ~ 70 DEG C，During production，Therefore the temperature of electrothermal tube must be improved，It is more difficult that temperature controls，Therefore product can be caused bad、Product yellowing phenomenon，The speed of injection can be slow，Using effect is bad，And hot mouth maintenance inconvenience.
Utility model content
This utility model is for above technical problem, it is provided that a kind of good heat conduction effect, heat radiation less, the structure of hot sprue of hot runner of high insulating effect, using effect is good, and injecting products performance is good, stable, zero defect, and injection is soon.
The technical solution adopted in the utility model is as follows, a kind of hot runner hot mouth, including hot mouth body, Hot nozzle point and Hot nozzle head, described hot mouth is the most internal is provided with sprue, mouth core runner and gum exudation mouth it is provided with in described Hot nozzle point, described sprue and mouth core flow passage, described Hot nozzle head part is socketed in hot mouth, and this is internal, its lower end has sealing, for forming annular sealing surface with mould, so that preventing from cementing leakage, described Hot nozzle head inwall upper part is an inclined-plane, the outer wall of described Hot nozzle point is correspondingly arranged on the inclined-plane matched, fixed by inclined-plane, Hot nozzle point is integrally attached in Hot nozzle head.
Preferably, described Hot nozzle head is connected on hot mouth by arranging external thread sleeve on the outer wall this is the most internal, it is simple to the dismounting of Hot nozzle head and conduction of heat.
Preferably, being provided with annular protrusion below the external screw thread on the outer wall of described Hot nozzle head, described annular protrusion withstands hot mouth body and forms an annular contact surface, in order to consolidates Hot nozzle head and Hot nozzle point and is convenient to conduction of heat.
Preferably, being provided with nut shape protruding below the annular protrusion on the outer wall of described Hot nozzle head, described nut shape projection is used for dismantling Hot nozzle head and Hot nozzle point.
Preferably, it is formed with spatial gaps between inwall and the gum exudation mouth of Hot nozzle point of described Hot nozzle head.
nullHot nozzle head of the present utility model be straight-tube shape and part be socketed in hot mouth this is the most internal，Hot nozzle head inwall upper part is an inclined-plane，And the outer wall of Hot nozzle point is correspondingly arranged on the inclined-plane matched，The wall thickness uniformity of formation is combined between Hot nozzle head and Hot nozzle point，Owing to being plane-plane contact form，Heat preferably passes to Hot nozzle point，Using effect is more preferable，When melted plastic cement flows in mouth core runner from sprue，Heat through electrothermal tube，Heat insulation effect is evenly，The plastic cement melt index concordance flowed out is high，The stability of product is strong，Further，Hot nozzle head is connected on hot mouth by thread bush, and this is internal，Nut shape it is provided with protruding below screw thread，When maintenance or dismounting and change，Convenient，And Hot nozzle of the present utility model point is owing to having annular protrusion，When injection, stability is high、Increase conduction of heat，It is not easy to rock.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is enlarged drawing at the A in Fig. 1.
Detailed description of the invention
Illustrate below in conjunction with the accompanying drawings, this utility model is introduced in detail, it will be appreciated that simply introduce detailed description of the invention of the present utility model below, and do not lie in restriction protection domain of the present utility model.
Common structure of hot sprue of hot runner, generally comprise hot mouth body 1, Hot nozzle point 2 and Hot nozzle 3, hot mouth body 1 is supported on mould 10 by the support ring 4 being enclosed within hot mouth body 1 upper end, hot mouth body 1 outside is wound with multi-turn and adds heat pipe 5, hot runner hot plastic cement in the mouth is heated with this, and it is provided with thermocouple 6, to detect temperature, it is interior with this fixing Hot nozzle point 2 that Hot nozzle 3 is socketed in hot mouth body 1, it is provided with sprue 11 in hot mouth body 1, mouth core runner 21 it is provided with in Hot nozzle point 2, sprue 11 connects with mouth core runner 21, melted plastic cement flows in mouth core runner 21 in sprue 11, then flow out from gum exudation mouth 22.
nullThis utility model，Improve on this basis，As shown in Figure 1-2，Hot nozzle 3 uses the structure of similar straight-tube shape，And allow Hot nozzle 3 part be socketed in hot mouth body 1 by external screw thread 32，It is outside that a part stretches out hot mouth body 1，This structure conduction of heat is good，And it is quick detachable，The lower end of Hot nozzle 3 be provided with sealing 31，Its outer wall props up mould 10 wall，Form annular sealing surface，The preventing from cementing leakage of this structure is effective，Hot nozzle 3 inwall upper part is an inclined-plane，Inclined-plane is outside，At an angle，And it is correspondingly arranged on, at the outer wall of Hot nozzle point 2, the inclined-plane matched，Pass through bevel-faced form，In Hot nozzle point 2 can be fixed on Hot nozzle 3 thus be fixed in hot mouth body 1，Owing to being plane-plane contact fixed form，It is more preferable that heat-transfer effect compares common hot mouth structure.
The improvement of above example, annular protrusion 33 and nut shape projection 34 it is disposed with below external screw thread 32, annular protrusion 33 props up hot mouth body 1, forms an annular contact surface, can consolidate Hot nozzle 3 and Hot nozzle point 2, minimizing is rocked, and conveniently heat transfer, when needing to dismantle Hot nozzle 3 and Hot nozzle point 2, screw nut shape protruding 34, between the inwall and the gum exudation mouth 22 of Hot nozzle point 2 of Hot nozzle 3, it is formed with spatial gaps 23, facilitates plastic emitting.
nullFurther，Hot nozzle head of the present utility model be straight-tube shape and part be socketed in hot mouth this is the most internal，Hot nozzle head inwall upper part is an inclined-plane，And the outer wall of Hot nozzle point is correspondingly arranged on the inclined-plane matched，The wall thickness uniformity of formation is combined between Hot nozzle head and Hot nozzle point，Owing to being plane-plane contact form，Heat preferably passes to Hot nozzle point，Using effect is more preferable，When melted plastic cement flows in mouth core runner from sprue，Heat through electrothermal tube，Heat insulation effect is evenly，The plastic cement melt index concordance flowed out is high，The stability of product is strong，Further，Hot nozzle head is connected on hot mouth by thread bush, and this is internal，Nut shape it is provided with protruding below screw thread，When maintenance or dismounting and change，Convenient，And Hot nozzle of the present utility model point is owing to having annular protrusion，When injection, stability is high、Increase conduction of heat，It is not easy to rock.
Embodiment of the present utility model simply introduces its detailed description of the invention, does not lies in and limits its protection domain.The technical staff of the industry may be made that some is revised under the inspiration of the present embodiment, therefore all equivalence changes done according to this utility model the scope of the claims or modification, belong in this utility model scope of the patent claims.
