Abstract
The utility model discloses a kind of hot nozzle cannot heat device, it is characterised in that：Heater body including metal, the heater body is provided with several mounting holes through upper and lower surface, the hot mouth being bonded with inner wall of the hole installing is provided with the mounting hole, the heater body lateral wall is cased with heating mantle, the heating mantle outer surface is provided with heating tank, the heating tank is embedded with heater strip, its key points of the technical solution are that multiple hot nozzle cannot heat devices are integrated in a heater body, demand is molded while to meet multiple cast gates, heater body is heated by heating mantle, reach and purpose heated at the same time to multiple hot mouths, save equipment cost, heating only needs a heater strip, it is neat and artistic.
Description
Technical field
Hot Runner System technical field is the utility model is related to, more specifically, it relates to a kind of hot nozzle cannot heat device.
Background technology
Hot flow path is to ensure that the plastics of runner and cast gate are kept molten by by the method for heating, Hot Runner System one
As be made of several parts such as hot nozzle, flow distribution plate, temperature control box and annex, hot mouth includes mouth core and mouth core retainer plate, in runner
Melt plastic cement is extruded by hot mouth, is injected mold cavity, is shaped to product.
The patent of invention of existing Application No. 201210101337.2 discloses a kind of embedded hot mouth main body of heater, bag
Hot mouth body is included, some grooves are offered on hot mouth body, groove is spiral shape or annular, and heater is embedded at the groove
In, heater is tubular heating element；Heater conducts heat hot mouth body by groove, realizes the heating to colloidal sol.
But but injecting products there are, it is necessary to using multiple hot mouth bodies, needed during multiple cast gates on each hot mouth body
Spiral groove is processed, difficulty of processing is big, of high cost；And it is required for adding using single one on each hot mouth body
Hot device, each heater are required for connection corresponding lead, and conducting wire is more and miscellaneous.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of hot nozzle cannot heat device, using
During multiple hot mouth body injections, it has low cost, without using the advantage of multiple heaters.
To achieve the above object, the utility model provides following technical solution：
A kind of hot nozzle cannot heat device, includes the heater body of metal, and the heater body is provided with through upper and lower surface
Several mounting holes, are provided with the hot mouth being bonded with inner wall of the hole installing in the mounting hole, the heater body lateral wall is cased with
Heating mantle, the heating mantle outer surface are provided with heating tank, and the heating tank is embedded with heater strip.
Preferably, the bottom wall of the heater body, which is located at mounting hole, is provided with hot mouth positioning sleeve.
Preferably, be provided with cooling water channel in the heater, the heater run through have communicated with cold water water route into
Water hole and apopore, the heating mantle run through the relief hole for having and being communicated with inlet opening, apopore.
Preferably, the cooling water channel is in a ring.
Preferably, the cross section of the heater body is in kidney-shaped or circle.
Preferably, the one of the cooling water channel is sloped downwardly, the inlet opening and apopore respectively with cooling water channel
Top is connected with bottom.
Preferably, the heating mantle is made of brass.
Preferably, the heating tank is helicla flute.
Compared with prior art, the utility model has the advantages that：
By the way that multiple hot nozzle cannot heat devices are integrated in a heater body, after being powered to heater strip, heater strip pair
Heating mantle heats made of copper, make heating mantle be rapidly heated, and contact the heat to heater body, and heater body conducts heat
To hot mouth, complete to be carried out at the same time multiple hot mouths the purpose of heating using a heater strip, save equipment cost, building ring
Border is clean and tidy；By setting cooling water channel, after being passed through cold water in cooling water channel, heater can quickly be cooled down, be easy to
Cool down to hot mouth, in order to the glue that breaks；Heater body is in kidney-shaped, cooling water channel in a ring, in order to make heat transfer uniform,
And then lift cooling effect；The height of water inlet is more than water outlet, when cooling is completed, easy to which water is discharged.

Embodiment
The utility model is described in further detail below in conjunction with attached drawing.
The present embodiment is only explanation to the utility model, it is not the limitation to the utility model, this area skill
Art personnel as needed can make the present embodiment the modification of no creative contribution after this specification is read, but as long as
All protected in the right of the utility model be subject to Patent Law.
A kind of hot nozzle cannot heat device, as shown in the figure, it includes heater body 1, heater body 1 is made of metal, has
Preferable heat transmitting；Heater body 1 is provided with several mounting holes 11 through upper and lower surface, is respectively provided with each mounting hole 11
There is the hot mouth 2 that the inner wall with mounting hole 11 is bonded, the bottom wall of heater body 1, which is located at mounting hole 11, is provided with hot mouth positioning sleeve
12, positioned for passing through the sharp-tongued of hot mouth 2, and to hot mouth 2；1 lateral wall of heater body is cased with heating mantle 3, heating
Set 3 is made of brass, and thermal conductivity is good, easy for installation；3 outer surface of heating mantle is provided with heating tank 31, and heating tank 31, which is embedded with, to be added
