The specific embodiment
With specific embodiment, the present invention is illustrated by reference to the accompanying drawings:
As shown in Fig. 4-9, a kind of mould of small transformers support, described mould includes 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 setting 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, forms a closed cavity between two square iron 5 and dynamic model backing plate 4, 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; After described solid plate 2 and moving platen 3 matched moulds, form the die cavity 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 is positioned at the cavity that square iron 5 and dynamic model backing plate 4, Bottom clamp plate 6 form; On described dynamic model mold insert 13, dynamic model backing plate 4, have slide in order to ejector retainner plate II 25, thimble fixed head II 24 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 is 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 described sliding tray is set, and described wedge shape jacking block 17 connects firmly with ejector retainner plate I 8; On described wedge shape jacking block 17, there is the guide runner that is 45 ° of angles with horizontal direction; In the guide runner of the slide block embedding wedge shape jacking block 17 in thimble fixed head II 24, also can move along described 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 in ejector retainner plate I 8.
In described ejector retainner plate I 8, release link 9 is set, in order to when the mould matched moulds, by the action of mould closure, makes release link 9 drive ejector retainner plate I 8, thimble fixed head I 7 to reset.
On described dynamic model mold insert 13, be fixed with dynamic model pin 27, in order to the column aperture on moulding small transformers support, described dynamic model pin 27 is from the horizontal by 45° angle.
In 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.
