The specific embodiment
For the technical scheme of the more detailed above-mentioned utility model of statement, below list specific embodiment and carry out Proof Technology effect; It is emphasized that these embodiment are not limited to limit scope of the present utility model for the utility model is described.
The mold liftout attachment that the utility model provides, as shown in Figure 1 to Figure 3, comprise one-level liftout plate 10, secondary liftout plate 20, die sinking pulling block 30 and latch 40, the upper end of described die sinking pulling block 30 is fixed in one end of described one-level liftout plate 10, drive described die sinking pulling block 30 to be synchronized with the movement, one end of described secondary liftout plate 20 is slidably connected to described latch 40, in other words, secondary liftout plate 20 can slide up and down along described latch 40, and one end that described secondary liftout plate 20 is connected with described latch 40 connects a movable bullet piece 22 by spring 21, particularly, described spring 21 is in compressive state, distance between latch 40 and secondary liftout plate 20 determines the compressed degree of spring 21, that is to say, movable bullet piece 22 is along the apparent motion of latch 40 1 sides.Described latch 40 is inserted in described die sinking pulling block 30, described die sinking pulling block 30 is provided with a draw-in groove 31, described movable bullet piece 22 matches with described draw-in groove 31, described latch 40 is also provided with groove 41 with the below of the side that described secondary liftout plate 20 is fixed, on described one-level liftout plate 10 and secondary liftout plate 20, be fixed with respectively one-level thimble 50 and secondary thimble 60, described one-level thimble 50 and secondary thimble 60 are located at respectively product 70 belows, for product 70 is ejected from die cavity.Preferably, described mold liftout attachment also comprises driving mechanism (not shown), and described driving mechanism is fixedly connected with described one-level liftout plate 10.Particularly, the motion process of mold liftout attachment of the present utility model is as follows:
1. after mold injection completes, driving mechanism drives one-level liftout plate 10 to move upward, drive toll bar pulling block 30 to move upward, due in the groove 41 of described movable bullet piece 22 in latch 40 now, so movable bullet piece 22 protrudes from the side of secondary liftout plate 20 simultaneously, and be stuck in draw-in groove 31, so secondary liftout plate 20 moves upward with one-level liftout plate 10 simultaneously, promote one-level thimble 50 and secondary thimble 60 ejecting products, preferably, please emphasis with reference to figure 3, described secondary thimble 60 is obliquely installed;
2. secondary liftout plate 20 moves upward along latch 40, when secondary liftout plate 20 skids off from groove 41, latch 40 activity compression bullet pieces 22, shrink spring 21, and movable bullet piece 22 is closed to secondary liftout plate 20 inside, namely movable bullet piece 22 is extracted out from draw-in groove 31, secondary liftout plate 20 and die sinking pulling block 30 are disengaged, that is to say, one-level liftout plate 10 departs from secondary liftout plate 20, now driving mechanism continues to drive one-level liftout plate 10 to promote one-level thimble 50, ejecting product 70.
This mode is to realize from machinery Double-ejection, and simple in structure, motion stabilization, without increasing in addition drive unit.
Preferably, please continue to refer to Fig. 1 to Fig. 3, the upper side 42 of described groove 41 is level and smooth inclined-plane.Movable bullet piece 22 can be skidded off smoothly from groove 41.
In sum, the mold liftout attachment that the utility model provides, comprise one-level liftout plate 10, secondary liftout plate 20, die sinking pulling block 30 and latch 40, the upper end of described die sinking pulling block 30 is fixed in one end of described one-level liftout plate 10, one end of described secondary liftout plate 20 is slidably connected to described latch 40, and one end that described secondary liftout plate 20 is connected with described latch 40 connects a movable bullet piece 22 by a spring 21, described latch 40 is inserted in described die sinking pulling block 30, described die sinking pulling block 30 is provided with a draw-in groove 31, described movable bullet piece 22 matches with described draw-in groove 31, described latch 40 is also provided with groove 41 with the below of the side that described secondary liftout plate 20 is fixed, on described one-level liftout plate 10 and secondary liftout plate 20, be fixed with respectively one-level thimble 50 and secondary thimble 60, described one-level thimble 50 and secondary thimble 60 are located at respectively product 70 belows.When one-level liftout plate 10 rises, secondary liftout plate 20 vertically slides, movable bullet piece 22 is due to the elastic force effect of spring 21, stretch out secondary liftout plate 20, due to stepping down of the groove 41 on latch 40, movable bullet piece 22 is stuck in draw-in groove 31, and one-level liftout plate 10 is synchronized with the movement with secondary liftout plate 20; When secondary liftout plate 20 skids off from groove 41, latch 40 Compress Springs 21 close in secondary liftout plate 20 movable bullet piece 22, and then depart from from draw-in groove 31, and one-level liftout plate 10 and secondary liftout plate 20 are departed from.
Obviously, those skilled in the art can carry out various changes and modification and not depart from spirit and scope of the present utility model utility model.Like this, if within of the present utility model these are revised and modification belongs to the scope of the utility model claim and equivalent technologies thereof, the utility model is also intended to comprise these change and modification.
