Preferably, it is formed with spatial gaps between inwall and the gum exudation mouth of Hot nozzle point of described Hot nozzle head.
Preferably, described mouth core runner is consistent with the bore of sprue connectivity part, and the bore of the mouth core runner of lower section is less than the bore of sprue.
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 has a terraced structure，Hot nozzle point periphery is provided with the fall terraced structure corresponding with terraced structure，Step fixed form，It is effective that the mouth core runner of Hot nozzle point connects docking with sprue，Process the simplest，The wall thickness uniformity of formation is combined between Hot nozzle head and Hot nozzle point，When melted plastic cement flows in mouth core runner from sprue，Heat through electrothermal tube，Heat radiation is few，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.
The hot mouth structure of common injection mo(u)lding, 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 full of multi-turn and is added 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 straight-tube shape，And allow Hot nozzle 3 be socketed in hot mouth body 1 by external screw thread 32 part，Be conducive to heat conduction、Dismounting，The lower end of Hot nozzle 3 be provided with sealing 31，Its outer wall props up mould 10 wall，Form annular sealing surface，Can preventing from cementing leakage，Hot nozzle 3 inwall has a terraced structure 35，Hot nozzle point 2 peripheries are provided with the terraced structure 23 corresponding with terraced structure 35，So，In Hot nozzle point 2 just can be fixed on Hot nozzle 3 thus be fixed in hot mouth body 1，The processing of this structure is simple，It is easily deformed to prevent Hot nozzle point 2 tube walls at step thinning，Can be by following design，Mouth core runner 21 is consistent with the bore of sprue 11 connectivity part，The bore of the mouth core runner 21 of lower section is less than the bore of sprue 11.
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 has a terraced structure，Hot nozzle point periphery is provided with the fall terraced structure corresponding with terraced structure，Step fixed form，It is effective that the mouth core runner of Hot nozzle point connects docking with sprue，Process the simplest，The wall thickness uniformity of formation is combined between Hot nozzle head and Hot nozzle point，When melted plastic cement flows in mouth core runner from sprue，Heat through electrothermal tube，Heat radiation is few，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.
