[detailed description of the invention]
Refer to shown in Fig. 2 and Fig. 3, the secondary ejecting mechanism of the present invention, it is applied in mould, and this mould includes upper mounted plate 100, caster 200, male template 300 and bottom plate 400, and in the present embodiment, this secondary ejecting mechanism includes:
Liftout plate 500, it is located on the bottom plate 400 of mould, and this liftout plate 500 includes upper ejector plate 510 and lower liftout plate 520；
First thimble 610, its one end is located in described upper ejector plate 510, and the other end contacts with product 700；
Base 800, it is located in described liftout plate 500, this liftout plate 500 is provided with corresponding holding tank and is located therein for this base 800, this base 800 includes two sides 810 and is provided with the bottom surface 820 of breach 821, these two sides 810 are located on this bottom surface 820, this base 800 is provided with four screws, and this four screw coordinates screw to fix this base 800 in the liftout plate 500 of mould, and these base 800 two sides 810 are additionally provided with the first hole, location 830；
Pushing block 900, it is rotatably arranged in described base 800, this pushing block 900 is provided with first rotating arm 910 at an angle to each other, second turning arm 920 and the 3rd turning arm 930, the second described turning arm 920 stretches out upper ejector plate 510, the 3rd described turning arm 930 stretches out lower liftout plate 520 by described breach 821, this pushing block 900 is provided with and positions the second hole, location that hole 830 is corresponding with first, this hole, the first location 830 and the second hole, location are combined with pin 940 so that this push pedal 900 rotates around this pin 940, in the present embodiment, it is 4.0mm that the second described turning arm 920 stretches out the vertical distance of upper ejector plate 510；
Second thimble 620, its one end is located on described first rotating arm 910, the other end contacts with product 700, this second thimble 620 is located at this end on first rotating arm 910 and is provided with flexible member 621 between liftout plate 500, this flexible member 621 is enclosed within this second thimble 620, in the present embodiment, this flexible member 621 is spring, and this flexible member 621 second time after mould die sinking is in compressive state when ejecting.
Refer to shown in Fig. 4, after mould die sinking, male template 300 separates with caster 200, under the effect of board push rod 410, liftout plate 500 moves upward, and liftout plate 500 drives the first thimble 610 and the second thimble 620 to move upward while moving upward, first thimble 610 and the second thimble 620 ejecting product 700, until the second turning arm 920 of push pedal 900 encounters male template 300, first time has ejected, and now also leaves the gap of 4.0mm between liftout plate 500 and male template 300.
Refer to shown in Fig. 5, when the second turning arm 920 of push pedal 900 encounters male template 300, push rod 410 continues to press on liftout plate 500 and moves, and now, pushing block 900 rotates around the positive hour hands of pin 940, first rotating arm 910 rotation drives the second thimble 620 to continue up and ejects, now flexible member 621 is compressed, and product 700 is continued to eject by the second thimble 620, until the second turning arm 920 goes in liftout plate 500, liftout plate 500 encounters male template 300, completes second time and ejects.After second time has ejected, the second thimble 620 to the first thimble more than 610 ejects 4.0mm.
During mould matched moulds; male template 300 is close with caster 200; liftout plate 500 drives the first thimble 610 and the second thimble 620 return, and flexible member 621 assists the second thimble 620 return, and the 3rd turning arm 930 of pushing block 900 encounters bottom plate 400 also can ensure the second normal return of thimble 620.
The foregoing is only preferred embodiment of the present invention, the structural feature of the present invention is not limited thereto.Such as, in other embodiments of the present invention, described pushing block 900 is provided with positioning convex column corresponding to the first hole 830, location, and this positioning convex column coordinates to be located in the first hole, location 830 so that push pedal 900 rotates around this positioning convex column.
The secondary ejecting mechanism of the present invention, by arranging rotatable pushing block 900 in liftout plate 500, only use a set of liftout plate 500 can Double-ejection easily, die size is little, takes up room little；Additionally simple in construction, easy to process, less costly；And because liftout plate need not be overlapped with shutter keyed two, thus without there is the defect that shutter is easily subject to crushing.
