Abstract
The utility model relates to a perfusion head for high-pressure liquid materials. A valve pipe, which can move up and down in a discharge pipe, is arranged in the middle of a mixing chamber; on the two sides of the mixing chamber, a set of high-pressure firing pins which communicates with an inlet pipe is arranged; on the two sides of the valve pipe, a refluence guide channel is arranged. As the high-pressure firing pins are arranged on the two sides of the mixing chamber, liquid materials spurts out in the state of mist by which means the liquid materials are mixed evenly, thus dispensing with the need for a mixing device, so the discharge pipe does not need to be arragned with a mixing device. In addition, the valve pipe which can move up and down along the discharge pipe clings the inner wall of the discharge pipe, when the perfusion is completed and the valve pipe is pushed down again, the residual material in the discharge pipe can be wiped off completely, dispensing with the need of solvents for cleaning. Furthermore, as the refluence guide channels are arranged on the two sides of the valve pipe, the materials can circulate from the refluence guide channel through the refluence pipe, namely, the valve part is a whole structure, so the perfusion and discharge can synchronize completely.
Description
Technical field:
The utility model relates to the injection-moulding device technical field, especially relates to a kind of liquid charging stock pouring head.
Background technology:
Along with industrial expansion and progress, injection-moulding device has been widely used in each industrial circle.In many injection-moulding devices, the liquid charging stock pouring head is a kind of common injection moulding tool.This pouring head has a mixing chamber, be connected with on the mixing chamber and be used to control the valve of telling material and control raw material circulating reflux more than at least two groups, different liquid charging stocks is told material by control valve enters back (telling material) in the mixing chamber via feeding pipe, perhaps flow to discharge nozzle and also mix by agitating device within it, or reclaim via the return duct circulation by the valve of control circulating reflux.Agitating device in the pouring head of this structure, its mixing chamber and discharge nozzle and discharge nozzle needs often to use special solvent that residual raw material is cleaned, and cleaning performance is not good; In addition, tell material and circulating reflux action, make that the accuracy of telling material synchronously is not high, and along with the wearing out of machine, the synchronism error of telling material will strengthen, thereby cause the job insecurity of pouring head because this pouring head uses two groups of above valves to control.
Summary of the invention:
The purpose of this utility model is to provide a kind of highly pressurised liquid raw material pouring head at the deficiencies in the prior art part.This highly pressurised liquid raw material pouring head need not to use solvent to clean, and perfusion is told material and can be reached complete synchronism.
For achieving the above object, the utility model comprises: mixing chamber and the discharge nozzle that is positioned at the mixing chamber lower end, be respectively arranged with feeding pipe and return duct on the mixing chamber, the middle part of mixing chamber is provided with a valved tube that can move up and down in discharge nozzle, the body both sides of valved tube offer the backflow guide groove, and the both sides of mixing chamber also are provided with one group of high pressure striker that links to each other with feeding pipe.
Described mixing chamber top is provided with oil cylinder, and the upper end of valved tube and the piston of oil cylinder are connected.
The position symmetry of described backflow guide groove, when valved tube rises to upper limit position, the bottom of backflow guide groove and the feeding mouth of return duct over against; And when valved tube drops to the lower position, the top of backflow guide groove and the feeding mouth of return duct over against.
The beneficial effects of the utility model are: because the mixing chamber two ends are provided with the high pressure striker, after liquid charging stock is adjusted to high pressure via the high pressure striker,, do not need agitating device to mix with vaporific form ejection, therefore, do not need to be provided with again agitating device in the discharge nozzle; In addition, can be close to the inwall of discharge nozzle along the valved tube that discharge nozzle moves up and down, after the perfusion action was finished, when valved tube was depressed once again, the raw material that can will residue in the discharge nozzle was removed fully, need not to use solvent to clean.In addition, because the body both sides of valved tube offer the backflow guide groove, raw material can circulate via return duct from the backflow guide groove, that is to say that valve portion is divided into same structure, thereby can reach the complete synchronism of pouring into when telling material.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is an outline drawing of the present utility model
Accompanying drawing 2 is one of vertical sectional structure schematic diagram of the present utility model (reflux state)
Accompanying drawing 3 is two (perfusion states) of vertical sectional structure schematic diagram of the present utility model
Accompanying drawing 4 is a transverse sectional view of the present utility model
The specific embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1～4: the discharge nozzle 10 that pouring head of the present utility model includes mixing chamber 100 and is positioned at mixing chamber 100 lower ends is respectively arranged with feeding pipe 20 and 21 and return duct 30 and 31 on the mixing chamber 100; The middle part of mixing chamber 100 is provided with a valved tube 40, and the upper end of valved tube 40 is connected with the piston 61 that is positioned at the oil cylinder 60 of mixing chamber 100 tops, and when oil cylinder 60 actions, valved tube 40 can move up and down in discharge nozzle 10.
The both sides of mixing chamber 100 are provided with one group of high pressure striker 50 and 51 that is connected with 21 with feeding pipe 20, and high pressure striker 50 and 51 effect are to spray after the liquid charging stock that will enter from feeding pipe 20 and 21 is adjusted to high pressure; Return duct 30 and 31 effect then be at pouring head when stopping to pour into, the liquid charging stocks of high pressure striker 50 and 51 ejections are reclaimed.
The body both sides of valved tube 40 offer the backflow guide groove 41 and 42 of position symmetry.When valved tube 40 rises to upper limit position, the feedback outlet of backflow guide groove 41 and 42 bottom and return duct 30 and 31 over against; And when valved tube 40 drops to the lower position, the feedback outlet of backflow guide groove 41 and 42 top and return duct 30 and 31 over against.
Operation principle of the present utility model below underdraws, when when needing to stop to pour under the situation such as mold exchange more, see shown in the accompanying drawing 2: at this moment, the piston 61 of oil cylinder 60 is depressed valved tube 40, it is entered in the discharge nozzle 10, on the one hand, promptly can't flow out from the fog-like liquid raw material of high pressure striker 50 and 51 ejections from discharge nozzle 10, and can only enter valved tube 40 both sides backflow guide groove 41 and 42 in recycling to realize, on the other hand, last time pouring into the raw materials that remain in the discharge nozzle 10 is cleared; When pouring into operation, see shown in the accompanying drawing 3: at this moment, the piston 61 of oil cylinder 60 rises, driving valved tube 40 withdraws from discharge nozzle 10, like this, the raw material that enters from feeding pipe 20 and 21 backs down high pressure striker 50 and 51, enters in the discharge nozzle 10 (telling material) with vaporific form ejection, and mix the back outflow within it, thereby finish the perfusion action.
