Abstract
The invention discloses a quick cleaning method of a charging barrel and a threaded rod of an injection molding machine, wherein the cleaning method comprises the steps of: receding the threaded rod for a distance by an injection action, manually receding the threaded rod to the maximal receding position of the threaded rod, so that certain amount of air can enter the charging barrel, the air extrudes the plastic material and generates extrusion and friction with the threaded rod and the charging barrel if the plastic material in the charging barrel is ejected at a high speed to well clean the charging barrel and the threaded rod so as to speed up the cleaning speed of the charging barrel and the threaded rod and improve the cleaning quality of the charging barrel and the threaded rod.
Description
Technical field
The present invention relates to the injection molding technology field, particularly a kind of when colour changing to the barrel of injection machine, the method that screw rod cleans.
Background technology
Injection machine is to utilize mould for plastics to process the main former of the plastic products of different shape thermoplastic or thermosetting material, and it can heating of plastic and molten plastic applied high pressure, molten plastic is penetrated and is full of mold cavity.The injecting systems of injection machine mainly partly is made up of barrel, screw rod etc., and the molten plastic in the barrel will inject mold cavity through screw rod and accomplish injection moulding under certain pressure and speed.In the course of work of injection machine, need often to use the plastics of various colors to carry out injection moulding, in order to prevent the situation of colour contamination, generally before the plastics of changing different colours, often need the barrel and the screw rod of injection machine be cleaned.
Conventional method of cleaning screw rod generally has two kinds: physics cleaning method and chemical cleaning method, there is certain defective in these two class methods.The physics cleaning method needs first dismantling screw, barrel to clean again, wastes time and energy, and efficient is lower, generally wants 12 hours, and operating personnel's working strength is very big.And the Chemical cleaning mode need make used additives and the special-purpose material that cleans, and it is longer to clean the time, generally wants 24 hours; Waste material after the cleaning can only be outwelled in vain; Cause a large amount of wastes, and can pollute, very ideal of this cleaning way cleaning performance of employing is arranged again environment.
Summary of the invention
To the deficiency of above-mentioned prior art, it is fast that the technical problem that the present invention will solve provides a kind of cleaning speed, the injecting machine material tube screw rod Rapid Cleaning method that cleaning performance is good.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of injecting machine material tube screw rod Rapid Cleaning method is characterized in that it comprises following method:
1) while hot plastic material residual in the injecting machine material tube is penetrated sky;
2) the bigger plastic material of adding particle gives and moulds action in the feeding device of injection machine;
3) give the screw rod slow astern set a distance of moulding to injection machine, screw rod is retreated the maximum position place that to retreat to screw rod with manual mode then;
4) with high rate of fire the plastic material in the barrel is penetrated;
5) repeating step 2 to 4 repeatedly cleans up until barrel and screw rod.
Preferably, the plastic material that said particle is bigger is ABS or HIPS.
Preferably, in step 1),, can add transparent plastic material earlier and give and mould action, and then transparent plastic material residual in the barrel is penetrated sky if injection machine was not worked when beginning.
Preferably, give in the step 3) and mould action and make the distance that screw rod retreats probably be 100mm.
Preferably, in step 2) in injection machine give the following fusing point that the temperature of moulding action is the bigger plastic material of said particle.
Technique scheme has following beneficial effect: this cleaning method give mould the action make screw rod slow astern set a distance after; Retreat the maximum position place that to retreat to screw rod through manually making screw rod; Just can get into air in certain amount in the barrel like this; When the plastic material in barrel penetrates at a high speed, in the time of the extruding of air and plastic material also can with screw rod and barrel extrusion friction, so just can play good cleaning action to barrel and screw rod; Thereby accelerate the cleaning speed of barrel, screw rod, improve the cleaning quality of barrel, screw rod.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
View when Fig. 1 implements for embodiment of the invention step 1).
Fig. 2 is an embodiment of the invention step 2) view when implementing.
View when Fig. 3 implements for embodiment of the invention step 3).
View when Fig. 4 implements for embodiment of the invention step 4).
The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described in detail.
This injecting machine material tube screw rod Rapid Cleaning method comprises the steps:
When 1) plastic injection-moulded in front completion need be changed the plastics of different colours; While hot plastics residual in the injecting machine material tube are penetrated sky (as shown in Figure 1); If do not work when injection machine begins; Can add transparent plastic material earlier and give and mould action, and then transparent plastic material residual in the barrel is penetrated sky.
2) in penetrating empty injection machine feeding device, adding the bigger plastic material of particle then gives and moulds action (as shown in Figure 2); The plastic material that above-mentioned particle is bigger can be ABS or HIPS; Injection machine gives the following fusing point that the temperature of moulding action should be the bigger plastic material of this particle; In the plastics of fusion, a certain amount of particle can be contained like this, thereby the frictional force between plastic material and screw rod and the barrel can be increased.
3) mould the screw rod slow astern set a distance that action makes injection machine through giving; Backway is decided according to the length of barrel; Be generally 100mm, with manual mode screw rod retreated to the maximum position place (as shown in Figure 3) that screw rod can be retreated then, can get into air in certain amount in the barrel like this.
4) one section higher injection pressure is set, injection speed 99% also is expelled to the end rapidly, promptly with the highest issuing velocity the plastic material in the barrel is penetrated, and can produce explosion (as shown in Figure 4) during ejaculation.Owing to just be mixed with air in certain amount in the barrel, when the plastic material in barrel penetrates at a high speed, when air pushes with plastic material also can with screw rod and barrel extrusion friction, so just can play good cleaning action to barrel and screw rod.Can barrel and screw rod be cleaned up as long as repeat above-mentioned steps 2-4 repeatedly.
Adopt this cleaning method can accelerate the cleaning speed of barrel, screw rod, improve the cleaning quality of barrel, screw rod.The method can play a multiplier effect at cleaning screw rod, barrel, can effectively practice thrift cleaning material and time, and statistics can be saved 2/3 above time and materials in actual the use, reaches the effect of quick colour changing.
More than a kind of injecting machine material tube screw rod Rapid Cleaning method that the embodiment of the invention provided has been carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as limitation of the present invention, and all any changes of making according to design philosophy of the present invention are all within protection scope of the present invention.
