Hot runner Technology, since the appearance forties in last century, has been saved time with its material-saving, High-Speed Automatic and raising quality of item
Enjoy people's concern Deng remarkable advantage and favor.Hot-runner nozzle be to mould die cavity inject hot melt material device, for
Hot melt material of different nature needs hot-runner nozzle to have the performance of different requirements, and the requirement to hot nozzle for the TOP-TIP is tight
Lattice, particularly the isothermal of sprue, sub-runner and hot nozzle is had high demands, required precision also very high.But, existing hot-fluid
Road hot nozzle, when plastic cement melt is after the cast gate of sprue bush, often occurs cast gate wire drawing, residual fraction plastic cement melt, or
The phenomenon such as repeatedly to repeatedly clean during molding, lead to the wasting of resources, yields is low, product quality cannot be met customer need.
Utility model content
The purpose of this utility model is, for the deficiencies in the prior art, provides a kind of anti-wire drawing interchangeable adiabatic flow road heat
Nozzle, smart structural design is so that plastic cement melt will not produce cast gate wire drawing phenomenon, the temperature outside nozzle core through the cast gate of sprue bush
Degree isothermal is good, and runner no dead angle, no plastic cement remain, and is easy to quick-replaceable color, good product quality, yields is high.
For achieving the above object, technical scheme provided by the utility model is:
A kind of anti-wire drawing interchangeable adiabatic flow road hot nozzle, including body and nozzle core, the upper outside of described body is provided with
This body bushing, the described top of body and lower inside are all symmetrically inlaid with heater element, and described nozzle core is led to sprue
Road is connected, and inside the heater element of described body lower part, the section of described nozzle core is in u font to described nozzle core, institute
The bottom of the nozzle core stated is provided with a through hole, and the lower, outer perimeter of described nozzle core is arranged with sprue bush, described cast gate be arranged with
The cast gate that described through hole communicates, described cast gate is in the font of falling u, and the gum exudation mouth of described cast gate is cross bore.
Further, described heater element is some heating strips, and the heating strip of body upper part and body lower part is all at least
Right for three.
Further, it is provided with class u shape indwelling area, the width in class u shape indwelling area between described nozzle core bottom and sprue bush
Consistent with the inboard width of sprue bush, class u shape indwelling area height be 0.2-0.5mm.
Further, described nozzle core, the central axis of sprue bush and the central axis of body coincide.
Further, a diameter of 6-8mm of described cross bore.
Compared with prior art, the beneficial effects of the utility model are:
The anti-wire drawing interchangeable adiabatic flow road hot nozzle that this utility model provides, is changed by isostructural to nozzle core and sprue bush
Enter so that plastic cement melt will not produce cast gate wire drawing phenomenon through the cast gate of sprue bush, the temperature isothermal outside nozzle core is good, plastic cement
Melt directly flows through arrival cast gate after nozzle core through hole by sprue, and no dead angle, no plastic cement remain, be easy to quick-replaceable color, subtract
The problem repeating that material is washed in molding repeatedly, good product quality are lacked, yields is high；It is primarily adapted for use in high-end electronic product, medical treatment, change
Cosmetic class, the unformed plastic shaping such as article of everyday use or colour changing molding.
Below in conjunction with the accompanying drawings with embodiment, the utility model is described in further detail.
Brief description
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is Fig. 1 part-structure enlarged diagram；
Fig. 3 is part-structure schematic diagram of the present utility model.
Specific embodiment
The anti-wire drawing interchangeable adiabatic flow road hot nozzle providing in conjunction with Fig. 1-Fig. 3, the present embodiment, including body 1 and nozzle core 2,
The upper outside of body is provided with this body bushing 3, and the top of body and lower inside are all symmetrically inlaid with heater element 4, nozzle core with
Sprue passage is connected, and inside the heater element of body lower part, the section of nozzle core is in u font to nozzle core, the bottom of nozzle core
It is provided with a through hole 5, the lower, outer perimeter of nozzle core is arranged with sprue bush 6, and cast gate is arranged with the cast gate 7 communicating with through hole, cast gate is in u
Font, the gum exudation mouth 8 of cast gate is cross bore, is supported and positioning nozzle core and body by this body bushing, and utilizes sprue bush and this
The connection of body further fix nozzle core, sprue bush also with mould fitted seal, prevent the plastic cement seepage of hot nozzle. wherein, heating
Element is some heating strips 41, and body upper part is right with the heating strip all at least three of body lower part；By heating strip is directly inlayed
Enter to be formed the heating system of heater in hot nozzle, so that the heat of heating strip is absorbed by hot nozzle completely, make the nozzle of hot nozzle
