Embodiment
Below, with reference to accompanying drawing and embodiment, the utility model is described further：
A kind of hot runner hot nozzle nozzle core 1, including inner flow passage 12 and the nozzle outer core 13 for being arranged at the outside of inner flow passage 12,
The inner flow passage 12 is the helical structure of up/down perforation.The inner flow passage 12 is double-spiral structure.In the inner flow passage
Wall is arc.The nozzle outer core 13 is cylindric.Shrink coning the nozzle outer core bottom 14.The nozzle outer core top
Portion is additionally provided with hanging platform 11.
The utility model additionally provides a kind of needle valve hot nozzle, including the internal nozzle body 2 for offering passage, is filled from channel bottom
The nozzle core of nozzle body 2 is fitted on, through the needle 4 of nozzle body 2, and is arranged on the nozzle first 3 of nozzle body bottom, the nozzle core is using as above institute
The hot runner hot nozzle nozzle core 1 stated.
As shown in figure 1, a kind of hot runner hot nozzle nozzle core 1, including inner flow passage 12 and runner periphery 13, described inside stream
Road 12 uses helical structure, and the stream that can increase colloidal sol internally runner 12 with this is grown, while including also can effectively increasing colloidal sol
Shearing in portion's runner 12, flowed beneficial to colloidal sol in the spiral inner flow passage 12, reduce the problem of material is spent.
Preferably, inner flow passage 12 uses double-spiral structure, than single coil configuration, can further increase colloidal sol internally
The stream length of runner 12, the problem of avoiding expecting to spend.
Preferably, the inner side of inner flow passage 12 is arcuate structure, can reduce friction to a certain extent, so as to reduce colloidal sol
The flow resistance of runner 12 internally, on the one hand, facilitate colloidal sol along inner flow passage 12 take advantage of a situation and under, on the other hand, avoid stream
Dynamic dead angle, the deposition of colloidal sol internally runner 12 is effectively reduced, avoid the need for the problem of colour changing that occurs during colour changing is uneven, have
Effect enhances the colour changing performance of the TOP-TIP using the hot runner hot nozzle nozzle core 1.
In use, the hot runner hot nozzle nozzle core 1 need to coordinate installed in hot runner hot nozzle nozzle body position, the hot runner hot is set
The nozzle outer core 13 of nozzle nozzle core 1 is cylindric, and is gradually tapered up in bottom and form coniform, setting hanging platform 11 at the top of nozzle core,
When using the hot runner hot nozzle nozzle core 1, columned nozzle outer core 13 can coordinate with nozzle body well, increase hot runner hot nozzle
The stickiness of nozzle core 1 and TOP-TIP, in addition, by the setting of hanging platform 11, can easily by the hot runner hot nozzle nozzle core 1 with
TOP-TIP is fixed, and strengthens the stability used.
As shown in Fig. 2 using a kind of needle valve hot nozzle of the hot runner hot nozzle nozzle core 1, including the internal nozzle for offering passage
Body 2, the nozzle core of nozzle body 2 is assembled to from channel bottom, through the needle 4 of nozzle body 2, and is arranged on the nozzle first 3 of nozzle body bottom, led to
The hot top hanging platform 11 of nozzle nozzle core 1 of runner is overheated, and the hot runner hot nozzle nozzle core 1 effectively can be fixed on needle valve hot by nozzle first 3
Nozzle.
During using the needle valve hot nozzle, the colloidal sol from runner flows into nozzle core 1 by the passage of nozzle body 2, and needle 4 drives in needle
Under the programme-control of dynamic device (not shown), the mechanical movement in the passage of nozzle body 2 opens and closes cast gate, and control is molten
Glue injects die cavity.There is double-stranded hot runner hot nozzle nozzle core 1 by this, colloidal sol add stream in nozzle core 1 it is long and
Shearing, can be sufficiently mixed, and avoid the occurrence of the problem of material is spent；Meanwhile when cast gate is closed, the hot runner hot nozzle nozzle of the Double-spiral
Core 1 can partly play a part of slag well, after being opened in needle-valve, make the cold sol that temperature reduces with PUR in the nozzle core 1
Inside it is sufficiently mixed, reduces cold burden, effectively lifts the quality of product.
It will be apparent to those skilled in the art that technical scheme that can be as described above and design, make other various
Corresponding change and deformation, and all these changes and deformation should all belong to the protection of the utility model claims
Within the scope of.
