Abstract
The invention discloses a nozzle filtering system. The nozzle filtering system comprises a nozzle and a filtering inner core. The nozzle filtering system is characterized in that during assembling, the filtering inner core is placed into the inner side of the nozzle, so that a sealing positioning face of the filtering inner core and an inner positioning face of the nozzle are installed in a matched manner; a rear side supporting block of the filtering inner core is supported on the side wall, the filtering inner core is prevented from being inclined during injection molding; in the normal use process, raw materials flow into the inner side of the filtering inner core through small holes of the filtering inner core from a chip removal area and are injected into a mold from a nozzle opening; large impurities larger than a gap between the chip removal area and the filtering inner core in the raw materials stay on the outer side of the chip removal area while some small impurities such as copper wires and copper chips enter the chip removal area and then stay in the chip removal area; after the impurities are accumulated and the whole chip removal area is filled with the impurities, disassembling is performed for cleaning; and after the nozzle is disassembled, the filtering inner core is ejected, all the impurities inside the chip removal area are scraped away while the filtering inner core is hot, then assembling is performed, and continuous production can be immediately carried out.
Description
Technical field
The present invention relates to a kind of injection machine part improvement project, particularly relate to a kind of nozzle filtration system.
Background technology
At present, nozzle is as the vitals of on injection head in injection machine, usually when injection moulding, due to raw material inevasible containing in a small amount lump or impurity as copper wire copper scale etc., injection machine production industry is in order to reduce costs simultaneously, again utilize feed back, used by certain proportion after feed back and raw material stir as raw material, this is more inevitable brings into impurity in injection machine.Therefore, easily block up and penetrate nozzle, and after stifled penetrating, often remove the cleaning of injection machine nozzle, because of increase labor strength, and reduce production efficiency.Feed back is recycled be can not get because having an economic benefit, and makes a lot of producer discard feed back, until abandon, causes economic loss and environmental pollution.But in injection mold, the raw material containing impurity can cause very large impact to mould when injection moulding, makes burn failure, production efficiency declines, and injection moulding cost is improved further, and therefore this is a urgent problem.
Summary of the invention
The object of this invention is to provide a kind of nozzle filtration system.
In order to achieve the above object, the present invention adopts following technical pattern: nozzle filtration system comprises nozzle and filters inner core two parts composition.Its feature: when assembling, inner core (2) will be filtered and put nozzle (1) inner side into, make the envelope of filtration inner core (2) anticipate plane (2-2) to coordinate with the plane decided at the higher level but not officially announced of nozzle (1) and install, filter the register nozzle mouth (1-2) of inner core (2), the Backside support block (2-1) filtering inner core (2) is supported in sidewall, prevent from filtering inner core (2) during injection moulding to tilt, back-up block (2-1) can pacify use needs placement 2-4 block to be advisable, and too much conference excessively affects Injection Molding; In normal use procedure, raw material from chip removal district (2-3) after filtration the aperture of inner core (2) flow into and filter inner core (2) inner side, then inject mould from nozzle mouth (1-2); The large impurity being greater than the gap between chip removal district (2-3) and filtration inner core (2) in raw material rests on outside, chip removal district (2-3), and after the small-sized impurity such as some copper wire copper scales enter chip removal district (2-3), under the block filtering the upper aperture of inner core (2), rest on chip removal district (2-3), when impurities accumulation is to certain degree, after impurity is full of whole chip removal district (2-3), then remove lower cleaning; After pulling down nozzle, with little iron pin through nozzle mouth (1-2), eject and filter inner core (2), scrape off sticking to the impurity filtering inner core (2) outside while hot, and scrape off the interior all impurity in the chip removal district (2-3) sticking to nozzle (1) inner side, put in back and can continue to produce at once.
The present invention compared to existing technology tool has the following advantages: nozzle filtration system, make injection raw material before injection molding, be introduced into filtration zone to filter, make impurities accumulation can not enter into the discharging opening of nozzle in chip removal district, can in advance anti-clogging cast gate, scratch mould, get rid of impurity in product, reduce product disqualification rate; This nozzle filtration system is disassembled conveniently, ejects filtration inner core after taking nozzle apart, and impurities adhere, outside filtration inner core, is easy to clear up the residue in nozzle.It is reliable and stable that the present invention adopts machinery to coordinate, and makes completing smoothly of product produce stable further.Effectively damage mould phenomenon occur, further increase the stability of whole mould.
