The present invention proposes a kind of secondary ejecting mechanism.
Under the general injection moulding condition of production, the front and back mould of mould is removed from the molds finished product after opening, it is desirable to have ejecting mechanism by it from the mold ejection demoulding.No matter ejecting mechanism is to adopt single or multiple part composition, and it ejects action is all once complete.But, owing to the shape of finished product is special, the demoulding needs, or the requirement such as volume production, if after ejecting at one section, finished product remains in die cavity, or cannot Automatic-falling time, it is necessary to be further added by one section and eject action.Such eject movements design, be called Double-ejection, or two-stage nitration ejects.Having a kind of secondary ejecting mechanism being Double Tops needle plate and combining in secondary ejection structure, the present invention is used on this Double Tops needle plate structure.In the present invention, as shown in Fig. 1, Fig. 3 and Fig. 5, secondary ejecting mechanism includes the guide 10 being removably connected on the mould foot 200 of mould, the support 21 being removably connected to mould the first ejector retainner plate 400 and the first drag hook 22 being articulated with on support 21, first drag hook 22 is away from one end of support 21 with fastener 25, and the first drag hook 22 coordinates with guide 10；In the process once ejected, first drag hook 22 hook is in the side of the second ejector retainner plate 500 of mould, second ejector retainner plate 500 moves with the first ejector retainner plate 400, when the first drag hook 22 moves to Double-ejection station with the first ejector retainner plate 400 and the second ejector retainner plate 500, guide 10 drives the first drag hook 22 to swing, and the second ejector retainner plate 500 is discharged, the second ejector retainner plate 500 stops mobile, and the first ejector retainner plate 400 continues to run with and completes Double-ejection.
Specifically, the first drag hook 22 and support 21 are all rectangle steel design, and both articulated manner are as hinged by rotating shaft 26.This guide 10 can be cam structure, it is possible to be structure or other guide function structures of gathering sill.The first corresponding drag hook 22 is provided with and is directed to force structure with guide 10 coordinates, such as swing arm etc..The guiding machinery power of guide 10 acts in swing arm, drives the first drag hook 22 flexible rotating, to complete the locking to Double Tops needle plate and unblock.The reset of the first drag hook 22 can force reset by the mechanical force of guide 10, it is possible to adopts elastic component to reset.
Embodiments of the invention 1: guide 10 includes two pieces of limited block (11a that gap is arranged, 11b), gap forms gathering sill 111, and gathering sill 111 has tilting section 112 and straightway 113, and the first drag hook 22 has, away from the position of its hinge side, the swing arm 23a extended with gathering sill 111.It is as follows that typing ejects control work process: in the process once ejected, swing arm 23a linearly section 113 moves, first drag hook 22 hook is on the second ejector retainner plate 500, second ejector retainner plate 500 moves with the first ejector retainner plate 400, when the first drag hook 22 moves to Double-ejection station with the first ejector retainner plate 400 and the second ejector retainner plate 500, tilting section 112 forces the first drag hook 22 to swing, and the second ejector retainner plate 500 is discharged, second ejector retainner plate 500 stops mobile, and the first ejector retainner plate 400 continues to move to and completes Double-ejection.Reseting procedure is as follows: Double Tops needle plate runs along original track, runs to when once ejecting station, and the guiding mechanical force of track forces the first drag hook 22 to reset, and fastener is on the second ejector retainner plate 500.
Embodiments of the invention 2: with reference to Fig. 2, guide 10 is cam structure, the cam surface of cam structure has tilting section (112 ') and straightway (113 '), first drag hook 22 has and extends the swing arm 23b contacted with cam surface, is provided with spring return (sign) in support 21.It is as follows that typing ejects control work process: in the process once ejected, swing arm 23b linearly section (113 ') is mobile, first drag hook 22 fastener is on the second ejector retainner plate 500, second ejector retainner plate 500 moves with the first ejector retainner plate 400, when the first drag hook 22 moves to Double-ejection station with the first ejector retainner plate 400 and the second ejector retainner plate 500, tilting section (112 ') drives swing arm 23a to force the first drag hook 22 to swing, and the second ejector retainner plate 500 is discharged, second ejector retainner plate 500 stops mobile, and the first ejector retainner plate 400 continues to move to and completes Double-ejection.Reseting procedure is as follows: Double Tops needle plate runs along original track, runs to when once ejecting station, and the mechanical force of the spring return (sign) in support 21 forces the first drag hook 22 to reset, and fastener is on the second ejector retainner plate 500.
The present invention is by adopting the structure of integrated steel, and adopt mechanical force to drive the structure that rotation and lever combine, make this typing secondary ejection structure can carry the ability reaching 4 tons of load, meanwhile, the coupling mechanism force of load is big, and overall structure reliability is high, good stability, long service life, structure itself is also easy, and processing is easily.
Further, swing arm 23 is removably connected to the first drag hook 22.
