Detailed description of the invention
With reference now to accompanying drawing, describing embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.
Referring to Fig. 1 to Fig. 3, die-casting forming die 100 of the present utility model includes rotating ejection mechanism 50 and the cover half 10 cooperated and dynamic model 20.Dynamic model 20 comprises moving clamping plate 21 successively along the die sinking direction (i.e. arrow A direction) of die-casting forming die 100, dynamic model props up bracer 22 and movable model core print seat 23.Moving clamping plate 21, dynamic model prop up bracer 22 and movable model core print seat 23 crosses an activity space 24 jointly, for the space needed for the mobile offer of the ejector retainner plate 51 that the following describes.Cover half 10 jointly crosses one when matched moulds with movable model core print seat 23 and is cast into die cavity 30, for molding die casting 200.Being assembled with a core guide post 25 on moving clamping plate 21, the first end of core guide post 25 is assembled on moving clamping plate 21, and the second end of core guide post 25 is along die sinking direction through movable model core print seat 23 and extends and is cast into die cavity 30.
As shown in Figures 2 and 3, rotating ejection mechanism 50 includes ejector retainner plate 51, pushing tow sleeve pipe 52, outer oblique gear 53 and the internal helical gear 54 coordinated with outer oblique gear 53.Ejector retainner plate 51 is contained in activity space 24, and ejector retainner plate 51 moves along die sinking direction in the die sinking process of die-casting forming die 100, it is provided that pushing tow power.Pushing tow sleeve pipe 52 is placed on core guide post 25 and this core guide post 25 rotational slide relatively, and namely pushing tow sleeve pipe 52 rotates simultaneously relative to core guide post 25, and also relative core guide post 25 slides.Outer oblique gear 53, in being sheathed on pushing tow sleeve pipe 52 regularly, makes outer oblique gear 53 and pushing tow sleeve pipe 52 be fixed together, thus being driven this pushing tow sleeve pipe 52 rotate and slide by outer oblique gear 53.Internal helical gear 54, in being built in movable model core print seat 23 regularly, makes internal helical gear 54 and movable model core print seat 23 be fixed together, so that internal helical gear 54 cannot rotate relative to movable model core print seat 23.Therefore in die-casting forming die 100 die sinking process, ejector retainner plate 51 is mobile in activity space 24 along die sinking direction, outer oblique gear 53 is driven to engage with internal helical gear 54 by the ejector retainner plate 51 of movement, owing to internal helical gear 54 is fixing, therefore the outer oblique gear 53 engaged with internal helical gear 54 just rotates on internal helical gear 54 and slides, pushing tow sleeve pipe 52 is driven to be the die casting 200 that ground in rotary moving pushing tow is cast in die cavity 30 by the outer oblique gear 53 rotated and slide, namely outer oblique gear 53 drives pushing tow sleeve pipe 52 while rotating relative to core guide post 25, also core guide post 25 slides relatively, thus reaching to eject die casting 200 in the way of rotational slide, more specifically, as follows:
Relatively the superior, ejector retainner plate 51 comprises mutually folds the first ejector retainner plate 511 and the second ejector retainner plate 512 set along die sinking direction, jointly cross between first ejector retainner plate 511 and the second ejector retainner plate 512 and needed for ejecting die casting 200, eject space for pushing tow sleeve pipe 52, first end of pushing tow sleeve pipe 52 is stretched to be placed in and is ejected in space 513, and the first end of pushing tow sleeve pipe 52 along this pushing tow sleeve pipe 52 radially outward from ring-like stopper 521, by ring-like stopper 521 with eject space 513 keep out prevent pushing tow sleeve pipe 52 from slipping from ejector retainner plate 51；Second end of pushing tow sleeve pipe 52 sequentially passes through outer oblique gear 53 and internal helical gear 54 and extends and be cast into die cavity 30 place along die sinking direction, it is preferably, core guide post 25, pushing tow sleeve pipe 52, outer oblique gear 53 and the internal helical gear 54 layout in concentric, so that the pushing tow work of pushing tow sleeve pipe 52 is more precisely reliable.Specifically, in the present embodiment, as shown in Figure 3, core guide post 25 is along die sinking direction beyond pushing tow sleeve pipe 52 and through being cast into die cavity 30, now, cover half 10 offers and is cast into the feeding-passage 11 that die cavity 30 connects, and is preferably that feeding-passage 11 is arranged along die sinking direction, and the second end of core guide post 25 is placed in feeding-passage 11 in stretching of cooperation, to guarantee that being cast into die cavity 30 die casting goes out the requirement of profiled member 200.Wherein, for making ejector retainner plate 51 more steadily reliable in the movement of activity space 24, therefore being provided with the lead 26 arranged along die sinking direction between moving clamping plate 21 and movable model core print seat 23, lead 26 is placed through on the first ejector retainner plate 511 and the second ejector retainner plate 512；For making outer oblique gear 53 better engage with internal helical gear 54, as shown in Figure 3, outer oblique gear 53 is partly screw in internal helical gear 54 when die-casting forming die 100 matched moulds, equally, outer oblique gear 53 is conflicted with ejector retainner plate 51 in the die sinking process of die-casting forming die 100, and outer oblique gear 53 departs from after die-casting forming die 100 matched moulds conflicts with ejector retainner plate 51.
Compared with prior art, ejector retainner plate 51, pushing tow sleeve pipe 52, outer oblique gear 53 and the internal helical gear 54 coordinated with outer oblique gear 53 is included due to rotating ejection mechanism 50 of the present utility model, ejector retainner plate 51 is contained in activity space 30, and ejector retainner plate 51 moves along die sinking direction in the die sinking process of die-casting forming die 100；Pushing tow sleeve pipe 52 is placed on core guide post 25 and this core guide post 25 rotational slide relatively, outer oblique gear 53 is in being sheathed on pushing tow sleeve pipe 52 regularly and driving this pushing tow sleeve pipe 52 rotational slide, internal helical gear 54 is in being built in movable model core print seat 23 regularly, therefore in die-casting forming die 100 die sinking process, ejector retainner plate 51 just moves along die sinking direction, the ejector retainner plate 51 of movement drive outer oblique gear 53 to engage with internal helical gear 54；Owing to internal helical gear 54 is fixed on, movable model core print seat 23 can not rotate again, so that outer oblique gear 53 with internal helical gear 54 engagement process on internal helical gear 54 rotate and slide, driven pushing tow sleeve pipe 52 in the die casting 200 that pushing tow is cast in die cavity 30 rotatingly and slidingly by the outer oblique gear 53 of rotational slide again, realize pushing tow sleeve pipe 52 to be ejected by die casting 200 in the way of rotational slide, so that rotating ejection mechanism 50 of the present utility model eject more steadily reliable and precision is higher, accordingly ensure that die casting 200 eject quality.Simultaneously, rotating ejection mechanism of the present utility model 50 by " pushing tow sleeve pipe 52 is sheathed on core guide post 25, outer oblique gear 53 solid on core guide post 25, internal helical gear 54 is fixed on movable model core print seat 23 and internal helical gear 54 and outer oblique gear 53 engage " go to realize pushing tow sleeve pipe 52 and eject die casting 200 in rotational slide mode so that the structure of rotating ejection mechanism of the present utility model 100 is more succinct.
The person of meriting attention, the power that ejector retainner plate 51 moves is provided by the external world, and this is the known of those of ordinary skill in the art, therefore does not repeat them here.
Upper disclosed is only preferred embodiment of the present utility model, certainly can not limit the interest field of this utility model, the equivalent variations therefore made according to this utility model claim with this, still belong to the scope that this utility model is contained.
