The specific embodiment
In conjunction with accompanying drawing and specific embodiment the present invention is explained:
Shown in Fig. 4-9, a kind of mould of small transformers support, described mould include top clamping plate 1, solid plate 2, moving platen 3, dynamic model backing plate 4, square iron 5 and Bottom clamp plate 6; Described top clamping plate 1 is provided with up and down with Bottom clamp plate 6; Described solid plate 2, moving platen 3, dynamic model backing plate 4 and square iron 5 are between top clamping plate 1 and Bottom clamp plate 6; Described square iron 5 is symmetrically arranged two, constitutes the cavity of a closure between two square iron 5 and dynamic model backing plate 4, the Bottom clamp plate 6; On described solid plate 2, be inlaid with cover half mold insert 12, on described moving platen 3, be inlaid with dynamic model mold insert 13; Form die cavity behind said solid plate 2 and moving platen 3 matched moulds in order to moulding small transformers support; Described mould is provided with ejecting mechanism; Described ejecting mechanism includes ejector retainner plate I 8, thimble fixed head I 7, ejector retainner plate II 25, thimble fixed head II 24, thimble I 14, thimble II 15 and draws material pin 22; Described ejector retainner plate I 8, thimble fixed head I 7 are positioned at square iron 5 and dynamic model backing plate 4, Bottom clamp plate 6 formed cavitys; On described dynamic model mold insert 13, dynamic model backing plate 4, have in order to ejector retainner plate II 25, thimble fixed head II 24 slide sliding tray; The above sliding tray and horizontal direction of dynamic model mold insert 13, dynamic model backing plate 4 is 45 ° of angles; Described ejector retainner plate II 25, thimble fixed head II 24 are positioned at described sliding tray, and the wedge shape jacking block 17 that ejector retainner plate II 25, thimble fixed head II 24 are moved along said sliding tray is set, and described wedge shape jacking block 17 connects firmly with ejector retainner plate I 8; Has the guide runner that is 45 ° of angles with horizontal direction on the described wedge shape jacking block 17; Also can move in the guide runner of the slide block embedding wedge shape jacking block 17 on the thimble fixed head II 24 along said guide runner; Described thimble I 14, thimble II 15 connect firmly with ejector retainner plate II 25 respectively, and the described material pin 22 that draws is fixed on the ejector retainner plate I 8.
On described ejector retainner plate I 8, release link 9 is set,,, makes that release link 9 drives ejector retainner plate I 8, thimble fixed head I 7 resets by the action of mould closes in order to when the mould matched moulds.
On described dynamic model mold insert 13, be fixed with dynamic model pin 27, in order to the column aperture on the moulding small transformers support, described dynamic model pin 27 is from the horizontal by 45.
On described ejector retainner plate I 8, be fixedly connected with limited block 19, in order to when the mould die sinking, the stroke of restriction ejector retainner plate I 8.
On described dynamic model mold insert 13 and dynamic model backing plate 4, be fixed with guide pillar II 32; On thimble fixed head II 24, ejector retainner plate II 25, be installed with guide pin bushing II 33; Described guide pillar II 32, guide pin bushing II 33 cooperate, and thimble fixed head II 24, ejector retainner plate II 25 motion processes are play the guiding role
Fixing guide pillar I 10 on described moving platen 3 in order in the mould open/close mold process, to play the guiding role, is mounted with guide pin bushing I 11 on solid plate.
The course of work of the present invention is:
The first step: mould is lifted between four guide pillars of injection machine, the centring ring on the mould is aimed at the injection machine locating hole, through pressing plate top clamping plate (mould cover half part) is connected on the steady job table top of injection machine then; Through pressing plate Bottom clamp plate (mould dynamic model part) is connected on the mobile working table top of injection machine;
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 3rd step: behind the mould matched moulds, through sprue bush, round arris edge advances cast gate and pours into mold cavity injection machine outside product, then cools off 20 seconds with the molten condition plastics, lets the abundant curing molding of plastics, die sinking.During die sinking, injection machine folding modular system drives dynamic model and partly retreats, and solid plate and moving platen separate; Product moves to the dynamic model direction with the dynamic model part, stops behind the mobile certain distance, and the top rod of injection machine makes 7 actions of thimble fixed plate I; Because thimble fixed plates II 25 cooperates with the guide runner of wedge shape jacking block through slide block; Thimble fixed plates II 24 and ejector retainner plate II25 do to be with horizontal direction the motion of 45 under 17 effects of wedge shape jacking block, thimble I14, thimble II15 eject product from dynamic model mold insert 13, simultaneously; Draw the material pin that stub bar is ejected from dynamic model mold insert 13, so far accomplish the one-shot forming process.During matched moulds, ejecting mechanism leans on release link 9 drives to reset, and prepares to work next time.
