Detailed description of the invention
With reference now to accompanying drawing, describe embodiments of the invention, element numbers similar in accompanying drawing represents similar element.
Refer to Fig. 1 to Fig. 3, die-casting forming die 100 of the present invention comprises secondary ejecting mechanism 40 and the cover half 10 cooperatively interacted and dynamic model 20.Dynamic model 20 comprises moving clamping plate 21, dynamic model back-up block 22 and movable model core print seat 23 successively along the die sinking direction (i.e. arrow A direction) of die-casting forming die 100, moving clamping plate 21, dynamic model back-up block 22 and movable model core print seat 23 cross an activity space 24 jointly, and the movement for the ejector retainner plate 41 that the following describes and secondary ejector retainner plate 42 provides requisite space.Dynamic model back-up block 22 has the breach 221 be communicated with activity space 24, and this breach 221 makes dynamic model back-up block 22 cross a stop part 222, for keeping out with the first abutting end 44a of the spill spin block 44 that the following describes.As shown in Figure 3, cover half 10 when matched moulds and movable model core print seat 23 jointly cross one and be cast into die cavity 30, go out die casting (not shown) for die cast.
As shown in Figure 2 to Figure 3, secondary ejecting mechanism 40 comprises ejector retainner plate 41, secondary ejector retainner plate 42, propulsion arm 43, spill spin block 44 and an installation shaft 45.An ejector retainner plate 41 and secondary ejector retainner plate 42 are mutually folded to be established, be preferably, ejector retainner plate 41 and secondary ejector retainner plate 42 are sheathed and form layer structure along die sinking direction, and an ejector retainner plate 41 and secondary ejector retainner plate 42 are in turn contained in activity space 24 along die sinking direction, by this activity space 24 for the movement of an ejector retainner plate 41 and secondary ejector retainner plate 42 provides space.Installation shaft 45 is arranged on an ejector retainner plate 41 along perpendicular to die sinking direction, and installation shaft 45 is also placed through on spill spin block 44, spill spin block 44 is rotated around installation shaft 45, and spill spin block 44 is separated out the first abutting end 44a and the second abutting end 44b by this installation shaft 45.First abutting end 44a extends in breach 221, and the first abutting end 44a faces along die sinking direction and stop part 222, can keep out mutually in die sinking process to make the first abutting end 44a with stop part 222.The below of the second abutting end 44b along die sinking direction with secondary ejector retainner plate 42 abuts, to be resetted by the second ejector retainner plate 42 driven rotary block 44 in matched moulds process.Propulsion arm 43 is assembled on secondary ejector retainner plate 42, and propulsion arm 43 extends along die sinking direction and is cast in die cavity 30, preferably, propulsion arm 43 is arranged in the surrounding of secondary ejector retainner plate 42 respectively, to make to put on power on the die casting that is cast in die cavity 30 evenly.Therefore in die-casting forming die 100 die sinking process, the position that ejector retainner plate 41 drives secondary ejector retainner plate 42 to move to the first abutting end 44a and stop part 222 along die sinking direction to keep out by the second abutting end 44b, now realizes once ejecting; Then the second abutting end 44b now continues to rotate along doing along die sinking direction around installation shaft 45 because of the first abutting end 44a and keeping out of stop part 222 in the moving process of die sinking direction at an ejector retainner plate 41, moved relative to an ejector retainner plate 41 by the second abutting end 44b pushing tow secondary ejector retainner plate 42 rotated, thus realize the object of Double-ejection.Particularly, in the present embodiment, spill spin block 44 is two, two spill spin blocks 44 are parallel to each other along the axis (fore-and-aft direction of the installation shaft 45 namely in Fig. 3) of installation shaft 45, and spill spin block 44 is arranged in one end (i.e. the front end of Fig. 3 ejector retainner plate 41) place of an ejector retainner plate 41, another spill spin block 44 is arranged in the other end (i.e. the rear end of Fig. 3 ejector retainner plate 41) place of an ejector retainner plate 41, each spill spin block 44 to having an installation shaft 45 and a stop part 222, to make ejecting of secondary ejecting mechanism 40 of the present invention more steadily reliable; Preferably, two spill spin blocks 44 are staggered along the axis of installation shaft 45, the ejecting force applied by spill spin block 44 pairs of secondary ejector retainner plates 42 to make ejector retainner plate 41 evenly, improve further and eject effect.Certainly, in other embodiments, the quantity of spill spin block 44 can also be one, three, four or five not etc., therefore not to be limited with above-mentioned citing.More specifically, as follows:
Composition graphs 4, first abutting end 44a extends the first protuberance 441 for abutting with stop part 222 along die sinking direction, be preferably, first protuberance 441 comprises a planar portions 4411 in the face of the surface of stop part 222 and is distributed in the cambered surface portion 4412 of both sides of planar portions 4411, more steadily reliably keep out with stop part 222 to make the first protuberance 441, because colliding the impact produced both effectively reducing, therefore ensure that the steady reliability ejected.Equally, second auxiliary section 44b protrudes out the second protuberance 442 abutted with secondary needle plate 42 along die sinking direction, be preferably, second protuberance 442 comprises a planar portions 4421 in the face of the surface of secondary ejector retainner plate 42 and is distributed in the cambered surface portion 4422 of both sides of planar portions 4421, more steadily reliably abut with secondary ejector retainner plate 42 to make the second protuberance 442, because colliding the impact produced both effectively reducing, therefore ensure that the steady reliability ejected.
Compared with prior art, because secondary ejecting mechanism 40 of the present invention comprises an ejector retainner plate 41, secondary ejector retainner plate 42, propulsion arm 43, spill spin block 44 and installation shaft 45, an ejector retainner plate 41 and secondary ejector retainner plate 42 are mutually folded to be established and is in turn contained in activity space 24 along die sinking direction, spill spin block 44 rotates around installation shaft 45 and is separated out the first abutting end 44a and the second abutting end 44b by this installation shaft 45, and the first abutting end 44a to extend in breach 221 and faces along die sinking direction and stop part 222, the below of the second abutting end 44b along die sinking direction with secondary ejector retainner plate 42 abuts, therefore in die-casting forming die 100 die sinking process, ejector retainner plate 41 by the second abutting end 44b drive secondary ejector retainner plate 42 to move to along die sinking direction position that the first abutting end 44a and stop part 222 keep out to realize once ejecting, then the second abutting end 44b now continues to rotate along doing along die sinking direction around installation shaft 45 because of the first abutting end 44a and keeping out of stop part 222 in the moving process of die sinking direction at an ejector retainner plate 41, moved relative to an ejector retainner plate 41 by the second abutting end 44b pushing tow secondary ejector retainner plate 42 rotated, thus realize the object of Double-ejection, thus make the Double-ejection action of secondary ejecting mechanism 40 of the present invention more smooth and easy, process very simple.Meanwhile, namely secondary ejecting mechanism 40 of the present invention only can realize Double-ejection by the cooperation of ejector retainner plate 41, secondary ejector retainner plate 42, propulsion arm 43, spill spin block 44 and an installation shaft 45, therefore simplifies the structure of secondary ejecting mechanism 40 of the present invention.
Upper disclosed is only the preferred embodiments of the present invention, certainly can not limit the interest field of the present invention with this, therefore according to the equivalent variations that the present patent application the scope of the claims is done, still belong to the scope that the present invention is contained.
