Abstract
The utility model discloses a kind of needle valve colour changing diversion spindle, belong to diversion spindle field, it is desirable to provide a kind of needle valve colour changing diversion spindle, it can reduce produces dead angle between cast gate department.Its drip irrigation device is：A kind of needle valve colour changing diversion spindle, including diversion spindle, it is provided with runner in the middle part of diversion spindle, described diversion spindle one end is provided with the seal face coordinated with cast gate department inner chamber closing, the one end of the diversion spindle away from end face is provided with the round platform with cast gate department end conflict fixation.
Description
Technical field
The utility model is related to a kind of diversion spindle, more particularly to a kind of needle valve colour changing diversion spindle.
Background technology
Hot flow path is used in injection mold, and the plastic pellet of thawing is injected into the heating group in the die cavity of mould
Part system.Cast gate department is the runner part for allowing the plastic material of melting to be injected into mould inside from the nozzle of injection machine, is used
In connection mould and the metal fittings of injection machine.
There is dead angle 21 with the cooperation position of cast gate department 2 in existing diversion spindle 3（There is gap can be with material stock）, inside dead angle
Hide material be easy for turning to be yellow over time, black, serious occurs as soon as carbonization.Material stock is brought out, and occurs as soon as product heterochromatic（Such as
There are the bad phenomenons such as stain, Huang Wen, black line in white products）, so when consumer product has colour changing demand, original design can not expire
Sufficient consumer product colour changing demand.
Utility model content
The purpose of this utility model is to provide a kind of needle valve colour changing diversion spindle, and it can reduce produces between cast gate department
Dead angle.
Above-mentioned technical purpose of the present utility model technical scheme is that：
Runner is provided with the middle part of a kind of needle valve colour changing diversion spindle, including diversion spindle, diversion spindle, described diversion spindle one end is set
The seal face coordinated with the closing of cast gate department inner chamber is equipped with, the one end of the diversion spindle away from end face is provided with and cast gate department end
Contradict fixed round platform.
By such scheme, diversion spindle is embedded in the inside of cast gate department, and needle is embedded in the end of cast gate department, from
And the material extruded in needle will not be entered in the gap between cast gate department and diversion spindle.Hot nozzle contradict diversion spindle round platform and
Diversion spindle seal face and cast gate department inwall is allowed to push against closing, so that the material allowed in runner will not enter diversion spindle and cast gate department
In interior gap.
Further, the diversion spindle is narrow footpath end close to one end of seal face.
By such scheme, narrow footpath end can conveniently say that diversion spindle is inserted into cast gate department.
Further, the narrow footpath end is provided with fillet.
By such scheme, the fillet at narrow footpath end can avoid its end can not be with cast gate department caused by being remained because of processing
The problem of being brought into close contact.
Further, the side of seal face is provided with escape positioned at round platform on the diversion spindle.
By such scheme, the end face of adjacent parts is close to when escape ensure that assembling.
Further, the runner is provided with the enlarging for being docked with hot nozzle close to round platform one end.
By such scheme, one end ecto-entad of the runner away from seal face constantly reduces, it is ensured that noted into mould
While entering the pressure of plastic grain, residual of the plastic grain in passage is reduced.
In summary, the utility model has the advantages that：
1st, diversion spindle is embedded in the inside of cast gate department, and needle is embedded in the end of cast gate department, so as to be squeezed in needle
The material gone out will not be entered in the gap between cast gate department and diversion spindle.Hot nozzle contradicts the round platform of diversion spindle and makes diversion spindle close
End-blocking face and cast gate department inwall push against closing, so as to allow the gap that the material in runner will not be entered in diversion spindle and cast gate department
In；
2nd, one end ecto-entad of the runner away from seal face constantly reduces, it is ensured that the injected plastic particle into mould
While pressure, residual of the plastic grain in passage is reduced.

Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Wherein identical parts are presented with like reference characters.It should be noted that the word used below in description
Language "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, word " bottom surface " and " top surface ", " interior " and
" outer " is referred respectively to towards or away from the direction of particular elements geometric center.
A kind of needle valve colour changing diversion spindle, as shown in figure 1, hot flow path 33 is used in injection mold, by thawing
Plastic pellet is injected into the heating component system in the die cavity of mould.Cast gate department 2 be allow melting plastic material from injection machine
Nozzle is injected into the part of runner 33 of mould inside, the metal fittings for connecting mould and injection machine.Melt
Plastic pellet is injected into the inside of mould under the cooperation of diversion spindle 3 and cast gate department 2, and cast gate department 2 contradicts with mould, it is ensured that water conservancy diversion
Plastic pellet in shuttle 3 can fast and accurately enter the inside of mould.Complete a kind of injection of the plastic grain of color
, it is necessary to change the plastic grain of another color after mould, in order to fast and effectively realize the replacing of different colours plastic grain,
And reduce and the situation that mixed difference occurs in plastic grain color occur.The utility model includes diversion spindle 3, and the one end of diversion spindle 3 is narrow
Footpath end 31, the narrow footpath end 31 is provided with fillet 312, and its end is provided with the seal face coordinated with the closing of cast gate department 2 inner chamber
311, the other end is provided with contradicts fixed round platform 32 with cast gate department 2 end, and is located at round platform 32 close to close on diversion spindle 3
The side in end-blocking face 311 is provided with escape 321.The middle part of diversion spindle 3 is provided with runner 33, and runner 33 is close to the one end of round platform 32
It is provided with the enlarging for being docked with hot nozzle 4.
Illustrate：
Diversion spindle 3 is embedded in the inside of cast gate department 2, and needle is embedded in the end of cast gate department 2, so as to be squeezed in needle
The material gone out will not be entered in the gap between cast gate department 2 and diversion spindle 3.Hot nozzle 4 contradicts the round platform 32 of diversion spindle 3 and allows and lead
Flow the seal face 311 of shuttle 3 and the inwall of cast gate department 2 pushes against closing, so that the material allowed in runner 33 will not enter diversion spindle 3 and pour
In gap in mouth department 2.
This specific embodiment is only to explain of the present utility model, and it is not to limitation of the present utility model, ability
