The specific embodiment
In conjunction with accompanying drawing and specific embodiment the present invention is explained;
Like Fig. 2, shown in Figure 3, a kind of Aero-Space are with the secondary ejecting mechanism of connector case mould, and described secondary ejecting mechanism includes ejector sleeve 31, gag lever post 33, spring 34, thimble 14 and release link 36; One end of said ejector sleeve 31 is positioned at the dynamic model 29 of housing mould, and the other end is fixed on the ejector retainner plate II 6; Described ejector retainner plate II 6 is fixed on the thimble fixed head II 7; One end of said thimble 14 is positioned at ejector sleeve 31, and the other end is fixed on the ejector retainner plate I 8; Ejector retainner plate I 8 is fixed on the thimble fixed head I 9; Described ejector retainner plate I 8, ejector retainner plate II 6, thimble fixed head I 9 and thimble fixed head II 7 are positioned at the cavity that dynamic model backing plate 4, Bottom clamp plate 11 and square iron 5 are constituted, and between ejector retainner plate II 6 and the dynamic model backing plate 4, all have the gap between ejector retainner plate I 8 and the thimble fixed head II 7; Gag lever post 33 is in order to the ejection stroke of restriction ejector retainner plate I 8, ejector retainner plate II 6; One end of gag lever post 33 is fixed on the thimble fixed head I 9 through screw; Gag lever post 33 with thimble fixed head I 9 to touching direction surely when moving, the termination of gag lever post 33 other ends gets in the groove that dynamic model backing plate 4 bottoms are set; Described gag lever post 33 is provided with the spring 34 that gag lever post is resetted; Described spring 34 is four; Described secondary ejecting mechanism is provided with release link 36, and an end of said release link 36 is fixed on the ejector retainner plate I 8; On said Bottom clamp plate 11, have in order to promote the K.O hole of secondary ejecting mechanism action.
Aero-Space are used the connector shell working process of mould:
The first step: mould is lifted between four guide pillars of injection machine, and centring ring 20 is aimed at the injection machine locating hole on the mould, and injection machine Bottom clamp plate reach compaction mold is fixed on the front and back seat board of injection machine then;
Second step: mode transfer, be about to injection machine folding stroke and adjust in the suitable mould total thickness, it is compressed, guarantee that mould open/close is smooth, the slide block folding is smooth;
The 3rd step: behind the mould matched moulds, injection machine through sprue bush 19, cover half mold insert I 25, cover half mold insert II 26, cover half mold insert III 28, gets into mold cavity through three cast gate cast with the molten condition plastics; Then cooled off 10 seconds, and let the abundant curing molding of plastics, die sinking; Along with moving after the dynamic model integral body; Cover half part is separated with product, and product is stayed in dynamic model 29 die cavities and is moved together with dynamic model, and shovel base 40 separates with slide block 39 gradually simultaneously; Angle Pin 37 begins effect to be pushed slide block 39 aside gradually, makes side channel and screw thread disengaging on slide block 39 and the product; So just accomplished forming process; The forming process of above-mentioned Aero-Space connector shell is an existing process in the prior art;
The 4th step: Aero-Space eject with connector shell: after the mould die sinking; The K.O hole that top rod on the injection machine passes on the Bottom clamp plate 11 promotes thimble fixed head I 9 setting in motions, and thimble fixed head I 9 drives ejector retainner plate I 8, release link 36, thimble 14 and spring 34 and moves to cover half; Under the effect of four springs 34, ejector retainner plate II 6 brings into operation, and drives ejector sleeve 31 and travel forward, thereby has realized that product at first throws off dynamic model mold insert 30, when ejector retainner plate II 6 moves to when fitting with dynamic model backing plate 4 ejector retainner plate II 6 and ejector sleeve 31 stop motions; At this moment, ejector retainner plate I 8 moves forward, in the groove that termination entering dynamic model backing plate 4 bottoms of gag lever post 33 other ends are set; Thimble 14 moves forward with ejector retainner plate I 8, withstands sprue and three cast gates, and drives product through three cast gates; Product is ejected ejector sleeve 31; Realize that product ejects smoothly from mould, carry out matched moulds again, along with the carrying out of mould assembling action; Under the effect of release link 36, secondary ejecting mechanism resets; Matched moulds carries out do action after accomplishing again, thereby realizes normal productive process.
The present invention does not detail part and is the existing technical pattern of prior art, does not do too much explanation at this.
