Abstract
For the NV nozzles on high fluidity material ejection formation machine, it includes nozzle body, anesthesia needle, sets anesthesia needle in the space of nozzle body, anesthesia needle front end can valve nozzles main body tapping channel, the oblique connection driving reciprocator in anesthesia needle rear portion;During normal condition, driving reciprocator props up anesthesia needle rear end so that the tapping channel of closing needle valve nozzles body head;During feed state, anesthesia needle rear end is left by driving reciprocator, the material in nozzle body can press sealed pin retreat so that the tapping channel on nozzle body head is left in anesthesia needle front end.Due to driving, reciprocator is arranged on nozzle housing, can quick-replaceable consumable accessory, therefore the downtime of machine can be preferably minimized, and the maintenance of whole machine can also become extremely simple.
Description
Technical field
The part on high fluidity material ejection formation machine is the utility model is related to, more particularly to nozzle and its component is situated between
Continue.
Background technology
In the part that production is made up of silica gel, rubber, wax or similar material, above-mentioned raw materials are to be injected into make by pressure
In pattern tool and solidification wherein is crosslinked.
During filling stage and cure stage, sulfurating stage, realized between machine nozzle and mould by pressure seal
Connection.Anesthesia needle in machine nozzle ensure that moulding mould and injection device separate.And it is close to moulding mould
On nozzle must be cooled by different methods or heat.
Nozzle (referred to hereinafter as NV (the Non- with anesthesia needle are used when processing above-mentioned material on injection machine or press injector
Return Valve) nozzle) it is industry common recognition.For such NV nozzles, the driving for being generally responsible for closed system work is reciprocal
Mechanism is disposed in the inside of NV nozzles.Such result is that processed material penetrates into the form of revealing and wraps up drive
Dynamic reciprocator finally blocks driving reciprocator, and this can cause the failure of closed system.And NV nozzles maintenance and again
Before coming into operation, it is necessary to take out, disassemble from machine and cleaned, so need to shut down and increase cost of labor.
Utility model content
The utility model patent technical problem to be solved is intended to overcome drawbacks described above, there is provided one kind is used for high flowing
Property material ejection formation machine on NV nozzles, pass through on NV nozzle exteriors side arrange be responsible for closing NV nozzles driving
Reciprocator realizes this purpose.
Technical scheme is used by the utility model solves above-mentioned technical problem:
For the NV nozzles on high fluidity material ejection formation machine, it includes nozzle body, anesthesia needle, in nozzle master
Anesthesia needle is set in the space of body, anesthesia needle front end can valve nozzles main body tapping channel, the oblique connection in anesthesia needle rear portion drives
Dynamic reciprocator;During normal condition, driving reciprocator props up anesthesia needle rear end so that closing needle valve nozzles body head
Tapping channel;During feed state, anesthesia needle rear end is left by driving reciprocator, and the material in nozzle body can press sealed pin
Retreat so that the tapping channel on nozzle body head is left in anesthesia needle front end.
Further the characteristics of be:After the driving reciprocator connecting bolt with the oblique connection of anesthesia needle.
Further the characteristics of be:It is connected after driving reciprocator connecting bolt with anesthesia needle with 45 degree of angles.
Further the characteristics of be:Driving reciprocator is arranged on outside nozzle body.
Further the characteristics of be:The fluid passage of temperature adjustment can be carried out to nozzle body by being provided with the nozzle body,
So circulated from the temperature adjustable fluid of outside input in the passage in the range of nozzle whole length, the constant temperature of nozzle can be kept.
Compared with prior art, the utility model has the advantage of:
Due to driving, reciprocator is arranged on outside nozzle body, can quick-replaceable consumable accessory, therefore the failure of machine is stopped
The machine time can be preferably minimized, and the maintenance of whole machine can also become extremely simple.
Brief description of the drawings
Fig. 1 is the profilograph under the utility model operation nozzle closed mode.
Fig. 2 is the profilograph under the utility model operation nozzle open mode.
Fig. 3 is anesthesia needle and driving reciprocator cooperation schematic diagram under the utility model operation nozzle closed mode.
Fig. 4 is anesthesia needle and driving reciprocator cooperation schematic diagram under the utility model operation nozzle open mode.
Embodiment
Herein below is that the utility model is further described with reference to the operation signal of accompanying drawing nozzle.
As shown in figure 1, the utility model NV nozzles are arranged between metered shot unit 9 and mould 7, for processing silicon
The similar materials such as glue, rubber, wax.
To prepare material to be processed in metered shot unit 9, the material passes through NV nozzle injections followed by pressure
Into mould 7.
In material filling and cure stage, NV nozzles face by pressure initiation between metered shot unit 9 and mould 7
Face seals.
NV nozzles include nozzle body 5, anesthesia needle 2, bolt 1 and driving reciprocator 8.Nozzle body 5 it is centrally disposed
Hole 5.1, anesthesia needle 2 move in 5.1.Anesthesia needle 2 is connected in 45 degree of angles with bolt 1, and bolt 1 is by being arranged in nozzle body 5
Outer driving reciprocator 8 moves back and forth, so that bolt 1 can together move with anesthesia needle 2.
NV nozzle of Fig. 1 signals in closure state.By driving reciprocator 8 to promote bolt 1 via inclined-plane 3 along openings
To anesthesia needle 2 is promoted, anesthesia needle 2 seals plastic hole 6, is so finally closed NV nozzles.
NV nozzle of Fig. 2 signals in open mode.Bolt 1 is retracted by stroke unit 8, and anesthesia needle 2 is via internal pressure
And depart from plastic hole 6, so finally open NV nozzles.
The gap of a very little is needed between above-mentioned bolt 1 and main body 5, to drive reciprocator 8 to drive bolt 1
Motion.When bolt movement, raw material can penetrate into the gap, and slowly outwards leak into outside nozzle.
The machine nozzle on injection machine and press injector for processing the similar materials such as silica gel, rubber, wax must be adjusted
Temperature(Cooling or heating).
Fluid temperature adjustment passage is designed with nozzle body 5, it includes feeder connection 5.4, passage 5.2,5.3, channel outlet
5.5.Passage 5.2,5.3 spreads all over nozzle body 5 and connected, and so can input temperature adjustment stream from outside by feeder connection 5.4
Body is simultaneously circulated by passage 5.2,5.3 in the range of the whole length of nozzle, then flows out temperature adjustment stream from channel outlet 5.5
Body, the temperature of whole nozzle is thus kept, so that whole stable production process.
