Further scheme is that access includes import, is engaged in this profession including outlet, import is oppositely arranged with outlet.
As can be seen here, cooling water can be increased in access and interior flowing time of engaging in this profession, it is ensured that cooling effect.
Further scheme is that access is set around the outer wall that nozzle covers.
As can be seen here, it is easy to processing and fabricating access.
Further scheme is the outer wall setting covered around nozzle of engaging in this profession.
As can be seen here, it is easy to processing and fabricating to engage in this profession.
To realize above-mentioned second purpose, the injection mold that the utility model is provided includes die and hot nozzle cooling device, heat
Nozzle cooling device fixing assembling is in die, and hot nozzle cooling device includes nozzle set, exchanges mouth, access with engaging in this profession, die include into
Portion is with going out portion, and it is to cover the first thread groove that outer wall spiral is set around nozzle to exchange mouth, access, engages in this profession and is set to cover outer wall spiral around nozzle
The second thread groove, and the first thread groove and the second thread groove alternate setting on the outer wall that nozzle covers；Access and phase of engaging in this profession
Meet at exchange mouth；Enter portion to be connected with each other with access, go out portion and interconnection of engaging in this profession.
From such scheme, cooling fluid flows into access from portion is entered, then flow to out portion from engaging in this profession, so as to complete cooling.
Brief description of the drawings
Fig. 1 is the structure chart of the utility model embodiment.
Fig. 2 is the structure chart at another visual angle of the utility model embodiment.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Embodiment
Referring to Fig. 1 and Fig. 2, hot nozzle cooling device 5 includes nozzle set 1, exchanges mouth 13, access 14 and engage in this profession 15, exchange mouth 13,
Access 14 and engage in this profession 15 be arranged at nozzle set 1 outer wall.Preferably, access 14 is with engaging in this profession 15 in nozzle set 1 outer wall surface processing
Thread groove, access 14 is the first thread groove, and it 15 is the second thread groove to engage in this profession, and the first thread groove and the second thread groove are around nozzle
Set outer wall alternates spiral setting.Access 14 15 intersects at engaging in this profession and exchanges mouth 13, exchanges mouth 13 and is located at nozzle covers 1 second
End, access 14 15 is mutually permanently connected with engaging in this profession by exchanging mouth 13.Import 11 is located at the second end and nozzle set 1 of access 14
First end, outlet 12 is located at the first ends of the second end engaged in this profession and nozzle set 1.Preferably, nozzle covers being shaped as 1 first end
It is circular.Import 11 and outlet 12 between be provided with nozzle set 1, import 11 with outlet 12 nozzle set 1 first end outer wall on along
The radial direction of first end and be oppositely arranged.Nozzle set 1 includes melted material import 16, and the first end of nozzle set 1 is melted material import
One end.
Hot nozzle cooling device 5 is fitted into injection mold（Accompanying drawing is not shown）Afterwards, hot nozzle cooling device 5 is by die（Accompanying drawing
It is not shown）Parcel, die and nozzle set 1 is contacted, so that exchange mouth 13, access 14 15 are wrapped in die with engaging in this profession.Melt material
Expect to enter air stream enter runner 2 from the melted material import 16 that nozzle covers 1, then die cavity 3 is flowed into from runner 2, so as to be cooled down in die cavity 3.
Because melted material temperature is higher, cause service life by bad shadow because long-time is in the condition of high temperature to avoid nozzle from covering 1
Ring, cooling fluid need to be used to cool down nozzle set 1.In the present embodiment, cover 1 outer wall surface in nozzle and be machined with twice screw thread
Groove, respectively access 14 and engage in this profession 15, access 14 15 intersects at engaging in this profession and exchanges mouth 13.It had both been the first of access 14 to exchange mouth 13
End, also for engage in this profession 15 first end.
Preferably, cooling fluid is water.Water enters portion from mould（Accompanying drawing is not shown）Access is flowed into again after flowing to import 11
14, and the outer wall for covering 1 around nozzle along access 14 flow to exchange mouth 13.After water flow to exchange mouth 13, water is again from exchange
Mouthfuls 13 flow to outlet 12, then go out portion from what outlet 12 flow to mould（Accompanying drawing is not shown）, subsequent water can flow to outside.Water from
During import 11 flow to exchange mouth 13 along access 14, the heat of nozzle set 1 is conducted to water, and the water with heat is again from friendship
Change mouth 13 and 15 flow to outlet 12 along engaging in this profession.With the lasting injection of dampening, the heat of the water in nozzle set 1 is constantly conducted to new note
The water entered, outside is flow to the water of heat from outlet 12.Therefore, water is directly contacted to be cooled down to nozzle set 1 with nozzle set 1,
So as to ensure cooling effect.Access 14 and engage in this profession 15 be around nozzle cover 1 outer wall set thread groove, be easy to the same of processing and fabricating
When can be directly realized by the assembling of hot nozzle cooling body 5 by directly assembling nozzle set 1, and be easy to the maintenance in later stage with changing work
Make.
