The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
Extremely shown in Figure 5 as Fig. 1, a kind of full-automatic step-feeding precise injection molding mould bases of the present utility model, comprise sprue bush 1, solid plate 2, moving platen 3 and pusher 4, described solid plate 2 comprises solid plate 21 and following solid plate 22, described going up between solid plate 21 and the following solid plate 22 is provided with upper runner mold insert 23 and lower flow channel mold insert 24, form runner 25 between upper runner mold insert 23 and the lower flow channel mold insert 24, following solid plate 22 offers the vertical run 26 that is communicated with for mold cavity 27, and sprue bush 1, runner 25, vertical run 26 and mold cavity 27 are interconnected; Described upper runner mold insert 23 is connected with pull bar 28, and the front end of described pull bar 28 is provided with pull head 29, and described pull head 29 passes lower flow channel mold insert 24 and is arranged at the porch of vertical run 26.After material belt type five metals terminal is located safely in mold cavity 27, matched moulds.The injection machine nozzle is injected into plastic melt in the mould from sprue bush 1, and plastic melt enters runner 25 through sprue bush 1, enters vertical run 26 again, enters in the mold cavity 27 then and five metals terminal cooling forming.Because the injection moulding mould bases adopts two mold insert formula runners 25, can shorten the length of sprue greatly, reduce the time of injection moulding cooling, improve production of articles efficient.
Cooling curing is to enough rigidity in mold cavity 27 when plastic melt, and injection machine pulling mould carries out die sinking.Be provided with between following solid plate 22 and the moving platen 3 be used to the resistance plug 8 that branch mould resistance is provided, because the material with fixed attention of resistance plug 8 and vertical run 26 is to the effect of pull bar 28 package powers, mould is opened from die joint I earlier, this moment is under the effect of pull bar 28, be positioned at some cast gate 6 fracture in the exit of vertical run 26, the side gate 7 that arranges between some cast gate 6 and the mold cavity 27 separates with the material that coagulates of vertical run 26.
Dynamic model continues to retreat, and mould is opened from die joint II again, and lower flow channel mold insert 24 pushed away pull bar 28 by force with the material that coagulates of vertical run 26 when die joint II opened.Last mould is opened from die joint III, and resistance plug 8 is extracted from following solid plate 22, and goods break away from the cover half die cavity.
Further, the discharge end of injection moulding mould bases is provided with and draws material mechanism 5 automatically.Described pusher 4 is double-deck rushing board mechanism, double-deck rushing board mechanism comprises upper strata push pedal 41 and lower floor's push pedal 42, described upper strata push pedal 41 is connected with fore-set 411, and described fore-set 411 passes lower floor's push pedal 42, and butt has spring 412 between described fore-set 411 and the lower floor's push pedal 42; Described lower floor push pedal 42 is connected be used to the goods push rod 421 that ejects goods, and described upper strata push pedal 41 is connected be used to the strip push rod 413 that ejects strip; Be provided with the block 43 for restriction lower floor push pedal 42 strokes between described upper strata push pedal 41 and the lower floor's push pedal 42.After finishing opening stroke, injection machine top rod promotes fore-set 411, and fore-set 411 promotes upper strata push pedal 41, and under the effect of spring 412, lower floor's push pedal 42 is followed upper strata push pedal 41 and moved together.Therefore, goods push rod 421 and strip push rod 413 eject the material belt type five metals terminal after the injection moulding simultaneously together, break away from the dynamic model die cavity.Lower floor's push pedal 42 is advanced behind the segment distance, is blocked by block 43 and halts, and at this moment goods have been finished the demoulding.Injection machine top rod continues to promote upper strata push pedal 41, and the push pedal 41 further strip push rods 413 that drive in upper strata draw the material that draws of material mechanism 5 to sell material hole 9 jackings of drawing of strip automatically, draw material mechanism 5 to begin strip is drawn the material action automatically.The upper surface of upper strata push pedal 41 is provided for limiting the limited post 44 of upper strata push pedal 41 strokes, and after limited post 44 touched moving platen 3, the stroke of upper strata push pedal 41 stopped.
After finishing the full-automatic demoulding, the pulling upper strata push pedal 41 of injection machine top rod and lower floor's push pedal 42 reset, and injection machine is finished mould assembling action, and injection machine is injected next time, continues to repeat the production that following one-period is carried out in above-mentioned action.Above-mentioned production process is accomplished without any letup, and has improved labor productivity and the economic benefit of enterprises of mould greatly.Mold actions is stable, and quality of item and injection cycle can both satisfy requirement of client.
Further, described moving platen 3 is provided with strip pilot pin 31, and in the process of matched moulds, the 9 pairs of strips in material hole that draw that strip pilot pin 31 injects strips position, make strip can accurate in locating in the die cavity of mould, guarantee the injection moulding size of goods.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
