Description
Technical field
The utility model relates to a kind of injection machine nozzle, and more particularly, it relates to a kind of nozzle that filters.
Background technology
Injection machine is to utilize mould for plastics to make the main former of the plastic products of various shapes thermoplastic or thermosetting plastics.Penetrating injection moulding is generally that resin material is melted in barrel, by the promotion of screw rod, melt is passed through to nozzle fast injection in mold cavity, then obtains injecting products through solidifying and setting.Nozzle is the transition portion that connects barrel and mould, but the spray chamber of nozzle or nozzle easily stop up in actual use, and cannot clear up its inside after obstruction, can only change whole nozzle.
Blockage problem mainly causes owing to containing metal impurities in raw material, for the cost that economizes in raw materials as much as possible, conventionally select crushed material or regrown material, but this class raw material contains many metal impurities conventionally, even through the absorption of powerful magnetic frame, still have the copper of 0.5-2 millimeter, aluminium, scolding tin, the metal impurities that stainless steel etc. cannot adsorb are mixed in naked eyes in raw material and cannot see clearly at all, therefore easily produce obstruction at spray chamber or the nozzle place of nozzle, particularly the nozzle of 1-2 mm dia and runner the most easily produce obstruction, although therefore saved cost of material, but but increase the cost of maintenance of equipment and maintenance simultaneously, and consider the factors such as stopping production, actual loss often exceedes the cost of conservation.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of filtration nozzle of avoiding metal impurities to cause obstruction.
For achieving the above object, the utility model provides following technical scheme: a kind of nozzle that filters, comprise nozzle body and connecting rod for being connected barrel and nozzle body, described nozzle body comprises the nozzle and the nozzle bar that removably connect, described nozzle bar is provided with the spray chamber that connects nozzle and barrel, in described spray chamber, be provided with filter cylinder, the openend of described filter cylinder is towards connecting rod, described filter cylinder lateral wall is provided with guiding gutter, described guiding gutter is through to filter cylinder bottom, and described guiding gutter bottom is provided with some perforation to the filter opening in filter cylinder.
Bottom in described filter cylinder is provided with holds slag chamber.
The tapered pore structure setting of described filter opening, its large openend toward the outer side.
Described guiding gutter is incline structure setting around filter cylinder lateral wall.
A kind of nozzle that filters, comprise nozzle body and connecting rod for being connected barrel and nozzle body, described nozzle body comprises the nozzle and the nozzle bar that removably connect, described nozzle bar is provided with the spray chamber that connects nozzle and barrel, in described spray chamber, be provided with filter cylinder, the openend of described filter cylinder is towards connecting rod, and described filter cylinder lateral wall is provided with guiding gutter, described guiding gutter is through to filter cylinder bottom, and described guiding gutter bottom is provided with some perforation to the filter opening in filter cylinder.By adopting technique scheme, along with the promotion of screw rod, when melt is expelled in mold cavity by nozzle, melt is through the filtration of filter cylinder, the metal impurities that cannot remove in melt are stayed in filter cylinder, melt after filtering is expelled to mold cavity from nozzle, therefore can avoids the spray chamber of nozzle or nozzle place to produce obstruction.

Detailed description of the invention
With reference to Fig. 1, Fig. 2, the utility model being filtered to nozzle embodiment is described further.
A kind of nozzle that filters, comprise nozzle body 1 and connecting rod 2 for being connected barrel and nozzle body 1, connecting rod 2 includes the conveyor chamber of conducting nozzle body 1 and barrel, nozzle body 1 comprises the nozzle 11 and the nozzle bar 12 that removably connect, nozzle 11 can be threaded connection with nozzle bar 12, nozzle bar 12 is provided with the spray chamber 121 that connects nozzle 11 and barrel, in spray chamber 121, be provided with filter cylinder 13, filter cylinder 13 is the structure setting of bucket shape, include filter cylinder 13 sidewalls, with the opening and filter cylinder 13 bottoms that lay respectively at filter cylinder 13 two ends, filter cylinder 13 is between nozzle 11 and connecting rod 2, the openend of filter cylinder 13 is towards connecting rod 2, filter cylinder 13 lateral walls are provided with guiding gutter 131, guiding gutter 131 is through to filter cylinder 13 bottoms, but do not extend to the openend of filter cylinder 13, therefore melt can be only that nozzle 11 directions flow to filter cylinder 13 bottoms, and cannot be that connecting rod 2 directions flow to filter cylinder 13 openends, guiding gutter 131 bottoms are provided with some perforation to the filter opening 132 in filter cylinder 13.After nozzle 11 and nozzle bar 12 are fastenedly connected, filter cylinder 13 is inserted in spray chamber 121, subsequently connecting rod 2 is fastenedly connected to the other end with respect to nozzle 11 at nozzle bar 12, and the charging aperture of the discharging opening of connecting rod 2 and filter cylinder 13 fits.When use along with the promotion of screw rod, when melt is expelled in mold cavity by nozzle, melt is through the filtration of filter cylinder 13, melt is flowed out from filter opening 132, and the metal impurities that cannot remove in melt are because volume is larger, therefore cannot flow out by filter opening 132, be trapped in filter cylinder 13 inner bottom parts, therefore can avoid the spray chamber 121 of nozzle or nozzle 11 places to produce obstruction.After using a period of time, nozzle body 1 can be disassembled simultaneously, after filter cylinder 13 is taken out and cleaned out, can reinstall into use, dismounting is simple and convenient, and reusable, is conducive to reduce use cost, is convenient to extensively promote the use of.
Bottom in described filter cylinder 13 is provided with holds slag chamber 133.Be that guiding gutter 131 is not provided with filter opening 132 with respect to holding 133 places, slag chamber, filter opening 132 is only arranged on the side of guiding gutter 131 near filter cylinder 13 openends, therefore on guiding gutter 131, be not provided with filter opening 132 with respect to a side of filter cylinder 13 bottoms, be positioned at the environment that slag chamber 133 is relative closure that holds of filter cylinder 13 bottoms, only there is the opening towards connecting rod 2, therefore be convenient to hold slag chamber 133 and be detained metal impurities, the metal impurities that cannot remove in centralized collection melt, cleaning after convenient concentrating.
The tapered pore structure setting of described filter opening 132, its large openend toward the outer side.The minimum diameter of filter opening 132 can be arranged to 1-2 millimeter, suitable with the nozzle hole internal diameter of nozzle, therefore the metal impurities that easily stop up nozzle can be trapped in filter cylinder 13, avoids it to stop up nozzle and runner.The simultaneously tapered pore structure setting of filter opening 132, changes and has adjusted melt after filter cylinder 13 the filters nowed forming in filter opening 132, utilizes the circulation area diffusion melt expanding, and is convenient to the filtration of a large amount of melts.
Described guiding gutter 131 is incline structure setting (do not identify in figure, the lateral wall that its structure is similar to tubular body is arranged with internal thread) around filter cylinder 13 lateral walls.Melt is after filter cylinder 13 filters, its part melt flows to nozzle 11 along guiding gutter 131, remaining most of melt is filtered in the spray chamber 121 between filter cylinder 13 and nozzle bar 12, therefore the guiding gutter 131 that is incline structure setting can be in harmonious proportion the melt filtering through different guiding gutters 131 again, is conducive to improve the mixing uniformity of melt after filtration.
