The utility model can also improve further below.
The nozzle ontology is in the shape of a rod.
The mounting groove is the helicla flute being arranged along nozzle body length direction, and the heater element in helicla flute can uniformly add
Hot nozzle ontology, so that one can be maintained at during plastic melt flows in the injection channel of nozzle ontology
Stable temperature avoids the injection molding quality for influencing plastic melt.Certain mounting groove is also possible to straight trough or annular groove.It is described
For straight trough along the length direction setting for being nozzle ontology, annular groove is the circumferencial direction setting of nozzle ontology.
The shape of the heater element is adapted with the shape of mounting groove.
Full heat-conducting glue is filled in the mounting groove.The heat-conducting glue fills full entire mounting groove.Heat-conducting glue is filled in fever
The place that element is not bonded with mounting groove inner wall, consequently facilitating the heat of heater element passes to nozzle ontology by heat-conducting glue,
And then the heating efficiency of the utility model is improved, avoid thermal loss.
The lateral wall of the bringing-up section is equipped with insulating layer, and the insulating layer is covered on the outer surface of heat-conducting glue.State heat preservation
Layer is alumina silicate fibre.To which the heat for guaranteeing that heater element generates can be preferably gathered on nozzle ontology, it is not easy to radiate
It goes out, the thermal loss for avoiding heater element from generating is excessive, heating efficiency is low.
The heater element is electrically heated rod or resistive heater or infrared heating silk or heat-generating pipe or PTC heater or pottery
Porcelain heater.
The rear end of nozzle ontology, very worker's installation and inspection is arranged in the power input of the heater element.
The beneficial effects of the utility model are:
(1) for the utility model by being concavely provided with mounting groove in the lateral wall of nozzle ontology, heater element is mounted on installation
In slot, the inner wall of heater element and mounting groove is in close contact, and heat caused by heater element is directly passed to nozzle ontology, is sent out
Thermal element is evenly heated the plastic melt in injection channel, so that plastic melt flowed in the injection channel of nozzle ontology
In the process, a stable temperature can be maintained at.Therefore the heating efficiency of the utility model is high, and fever is uniform, heat loss
It is few, more than half is reduced compared with conventional, electric-resistance fever circle heat loss.The utility model nozzle has functionally merged heater element
Heating function, keep injection nozzle structure compact, be conducive to the molding die for being applicable in special shape.
(2) also, outer-enwraped type heating coil is compared, the heater element of the utility model is embedded in mounting groove, this is practical new
The heat-conducting area ratio of type increases, while reducing thermal resistance using heat-conducting glue filling between heater element and jet nozzle, favorably
In the conduction of heat.
(3) in addition, theoretically heater element and air are contactless since heater element is without exposed surface, heater element with
Air reduces thermal loss without heat exchange.So Novel injection nozzle faces to have significantly than outer-enwraped type heating coil in hot merit efficacious prescriptions
Power savings advantages.
(4) also, the heater element of the utility model has power stability, uniform feature of generating heat.
(5) moreover, because the heater element of the utility model is embedded in mounting groove, the size rule of nozzle not will increase
Lattice and volume, therefore the structure of the utility model is compact, small in size, appearance is neat, and intensity is reliable；It examines and convenient for disassembly and assembly.This
Utility model can satisfy the injection molding machine for having special construction requirement to nozzle, if draw ratio is more than 10 nozzle.
(6) more have plenty of, bonding strength is high in this patent structure, under the conditions of the injection pressure for adapting to different operating conditions
Deformation stretches.
