Specific embodiment
In order to make the objectives, technical solutions, and advantages of the present invention clearer, right with reference to the accompanying drawings and embodiments
The present invention is described in further detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and does not have to
It is of the invention in limiting.
A kind of secondary ejecting mechanism of automobile lamp card wire structure of the invention, as illustrated in figs. 2-7, including dynamic model 1, thimble
Plate 2, bottom plate 3, the first thimble 4, the second thimble 5, limit sleeve 6 and elastic component 7 with card wire structure, dynamic model 1,2 and of ejector retainner plate
Bottom plate 3 is sequentially arranged in parallel, the first through hole 11 and the second through-hole of setting guidance the first thimble 4 and the second thimble 5 in dynamic model 1
12, one end of the first thimble 4 is fixed on ejector retainner plate 2, and the other end is placed in first through hole 11, by 2 vertical shift of ejector retainner plate,
Drive the first thimble 4 along 11 vertical shift of first through hole.The one end of second thimble 5 with card wire structure is arranged in the second through-hole 12
Interior, the gap between 2 upper surface of dynamic model forms card wire structure；Limit sleeve 6, limit is fixedly installed in the other end of second thimble 5
Position set 6 includes the first stepped part 61 and second step ladder 62, and the first stepped part 61 is greater than first through hole 11, i.e. second step ladder 61
It cannot be introduced into first through hole 11, and then limit the upper pan position of the second thimble 5, opened up on ejector retainner plate 2 and allow the first rank
The third through-hole 21 that terraced portion 61 passes through limits pan position in second step ladder 62 by third through-hole 21.Second thimble 5 passes through bullet
Property part 7 is fixedly connected with bottom plate 3；Wherein, elastic component 7 can be spring.
When product is ejected, it is necessary first to be opened dynamic model and cover half, as shown in Fig. 2, after the completion, driving thimble
Plate 2 moves up, and moves up the first thimble 4, product is ejected, while the second thimble 5 is by 7 thrust of elastic component, but
By the blocking of third through-hole 21, the second thimble 5, which is followed by the first thimble 4 and synchronizes, to be moved up, until the second through-hole 12 stops first
Stepped part 61；At this point, product has been ejected dynamic model, first stage ejection terminates, as shown in Figure 6.Then, ejector retainner plate 2 drives
First thimble 4 continues to move up, blocking of first stepped part 61 by the second through-hole 12, and the second thimble 5 of limitation continues to move up；At this time
Product has a upward thrust, and the card wire structure of product occurs elastic deformation, is detached from the second thimble 5, the ejection of second stage
Terminate, as shown in Figure 7.
It in one embodiment, further include support rod 8, support rod 8 is used to support the second thimble 5, when the die is closed, ejector retainner plate 2
It moves down, contacts the second thimble 5 with support rod 8, support rod 8, which limits the second thimble 5, to be continued to move down, by matching with third through-hole 21
It closes, the second thimble 5 is fixed, guarantee that the second thimble 5 is remain stationary in casting.Also the guiding as elastic component 7 simultaneously
Bar, on the contrary elastic component 7 is offset to both sides in compression.
In one embodiment, the first thimble 4 is arranged two, and the two sides of the second thimble 5 are symmetrically arranged in.Such energy
Enough guarantee that product can be ejected steadily.
In one embodiment, limited block 9 is set on ejector retainner plate 2, limited block moves up distance for limiting ejector retainner plate 2, into
And control product ejection distance.By replacing limited block 9, adjusting ejector retainner plate 2 and moving up distance and strike makes product be detached from the second thimble
5, to improve production efficiency.In one embodiment, limited block 9 is fixed by screw, adjusts limited block 9 by screw
Height, and then realize adjusting to 2 moving distance of ejector retainner plate.It avoids repeating to replace limit plate 9, improves adjusting efficiency.
In one embodiment, the fourth hole 22 for allowing second step ladder mobile is opened up on ejector retainner plate 2, when ejector retainner plate 2
When moving up, elastic component 7 stretches, and part of it is in fourth hole 22, is equivalent to fourth hole 22 and is used as its guide groove, guidance
Elastic component 7 stretches vertically.
The foregoing is merely a prefered embodiment of the invention, practical range not for the purpose of limiting the invention；If not departing from this
The spirit and scope of invention, modify or equivalently replace the present invention, and should all cover the protection in the claims in the present invention
In range.
