Abstract
The invention discloses an injection nozzle with a filtering device. The injection nozzle has a nozzle header connected with a host barrel, an injection passage provided in the nozzle header, and a filter in the nozzle header. The front outer edge of the filter and the passage in the nozzle header are sealed fit, the outer diameter of the middle part of the filter is smaller than the outer diameter of the front outer edge of the filter; a filtering gap is formed between the nozzle header and the filter, the outer side wall at the middle part of the filter is provided with a plurality of feeding grooves and discharging grooves arranged at intervals, when the material flow passes through the filter, the impurity in the material can be filtered off and the colors of any product from color material can be more even.
Description
Technical field
The present invention relates to the matching used shower nozzle of a kind of injection machine.
Background technology
At present, matching used shower nozzle on the injection machine, shower nozzle one end is connected with barrel on the main frame, the shower nozzle mouth of the other end and mould cooperate, and employed aborning raw material exists some impurity inevitably, and originally nozzle structure does not have filter, feed stream directly is injected into the mould by shower nozzle from barrel, therefore, impurity can not be filtered out, the quality of product can not be controlled well.
Summary of the invention
At the defective of technique scheme, the object of the present invention is to provide a kind of injection made showerhead with filter, can filter out impurities in raw materials, also can be so that the product colour of coloured raw material is more even.
For achieving the above object, be achieved by the following technical solution:
Injection made showerhead with filter, has the shower nozzle base that is connected with the main frame barrel, has injection channel in the shower nozzle base, it is characterized in that: be built-in with filter at the shower nozzle base, described filter rear section and shower nozzle base are threaded fixing, wherein the front outer of filter and shower nozzle base internal channel are sealed and matched, the external diameter of filter mid portion is less than the external diameter of filter front outer, between shower nozzle base and filter, form one and filter the space, the mid portion lateral wall of its filter is provided with a plurality of feed wells and blow tank, feed well and blow tank are provided with at interval, be provided with a plurality of feeding-passages and shower nozzle base internal channel is connected at the fore-end of filter, feeding-passage is communicated with feed well simultaneously, and the tapping channel in blow tank and the filter is connected; Shower nozzle mouth and filter rear section are threaded, and the internal channel of a plurality of tapping channels and shower nozzle mouth is connected.
Be an outstanding cone on its front end end face of described filter, a plurality of feeding-passages are arranged on the periphery of outstanding cone.
Adopt the injection made showerhead of said structure, in the time of injection machine work, after materials flow is come in from the passage of shower nozzle base, feeding-passage by filter enters in the feed well of filter mid portion, the end of feed well can stop up materials flow, after being under pressure, the groove edge owing to can overflow in existence filtration space, materials flow, the materials flow in each road feed well all pours in to adjacent blow tank with same direction, form the materials flow of rotation, lead to shower nozzle mouth internal channel from tapping channel again, finish injection moulding process, at this moment, impurity in the materials flow is owing to the reason of weight and volume has been left in the feed well, played the effect of impurity screening, can after a stage is finished in work, the filter in the shower nozzle have been taken out, get rid of the impurity of leaving over, shower nozzle can recycle.In addition, materials flow becomes a plurality of passages from original one corridor diversion by shower nozzle the time, and in the time of can be from the feed well turn of tidal stream to blow tank, the materials flow that forms rotation can further be mixed the color in the materials flow more even.
Description of drawings
Fig. 1 is a stereochemical structure exploded view of the present invention;
Fig. 2 is a profile of the present invention.
The specific embodiment
As shown in Figure 1 and Figure 2, have the injection made showerhead of filter, have the shower nozzle base 1 that is connected with the main frame barrel, have injection channel 11 in the shower nozzle base, be built-in with filter 2 at shower nozzle base 1.Described filter 2 rear sections 21 and shower nozzle base 1 are threaded fixing, wherein the front outer 22 of filter 2 and shower nozzle base 1 internal channel 11 are sealed and matched, the external diameter of filter 2 mid portions 23 is less than the external diameter of filter 2 front outers 22, thereby between shower nozzle base 1 and filter 2, form a time of filtration 3, mid portion 23 lateral walls of its filter are provided with a plurality of feed wells 24 and blow tank 25, and feed well 24 and blow tank 25 are provided with at interval.The front end end face of filter is provided with a plurality of feeding-passages 26 and shower nozzle base internal channel 11 is connected, and also is communicated with feed well 24 simultaneously, and the tapping channel 27 in blow tank 25 and the filter 2 is connected; Shower nozzle mouth 4 and filter 2 rear sections 21 are threaded, and the internal channel 41 of a plurality of tapping channels 27 and shower nozzle mouth 4 is connected.Have an outstanding cone 28 on described filter 2 its front end end face faces, a plurality of feeding-passages 26 are arranged on the periphery of outstanding cone 28, enter in the feeding-passage 26 after can shunting better the materials flow that injection channel 11 is poured into.
In the time of injection machine work, after materials flow is come in from the internal channel 11 of shower nozzle base 1, feeding-passage 26 by filter 2 enters in the feed well 24 of filter 2 mid portions 23, the end of feed well 24 can stop up materials flow, after being under pressure, filter space 3 owing to exist, the materials flow groove edge of can overflowing, materials flow in each road feed well 24 all pours in to adjacent blow tank 25 with same direction, forms the materials flow of rotation, leads to shower nozzle mouth 4 internal channels 41 from tapping channel 27 again, finish injection moulding process, at this moment, the impurity in the materials flow has played the effect of impurity screening owing to the reason of weight and volume has been left in the feed well 24, can be after a stage be finished in work, filter in the shower nozzle 2 is taken out, get rid of the impurity of leaving over, shower nozzle can recycle.In addition, materials flow becomes a plurality of passages from original one corridor diversion by shower nozzle the time, can be from feed well 24 turns of tidal stream to blow tank 25 the time, and the materials flow that forms rotation can further be mixed the color in the materials flow more even.
