Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 and Fig. 2 show schematically show the secondary ejecting mechanism of the band oblique top according to a kind of embodiment of the present utility model.
As shown in the figure, comprise can the front template 1 of folding and rear pattern plate 10 for this device.
Rear pattern plate 10 is provided with the first push pedal 3, second push pedal 7 and push rod 14.
First push pedal 3 is fixedly connected with one end of push rod 14.
First push pedal 3 both sides are respectively equipped with oblique top guide rod 6.
First push pedal 3 is also fixed with guide pillar 8.First push pedal 3 is moved along guide pillar 8.
Rear pattern plate 10 is also fixed with multiple oblique top mold insert 4.Multiple oblique top mold inserts 4 lay respectively at the outside of oblique top guide rod 6.
Second push pedal 7 is fixed with two crowded bars 22 of cutting somebody's hair.
Push rod 14 is fixed with thimble panel 16 and Ejector Retainer Plate 17 away from one end of the first push pedal 3.
Thimble 11 is provided with between thimble panel 16 and Ejector Retainer Plate 17.
Ejector Retainer Plate 17 is provided with multiple fixing mold insert 20.Fixing mold insert 20 is provided with the fixing accommodating hole 201 matched with crowded bar 22 of cutting somebody's hair.The position of fixing accommodating hole 201 is corresponding with crowded bar 22 of cutting somebody's hair.
Thimble panel 16 is provided with movable insert 21 corresponding to multiple and fixing mold insert 20.Movable insert 21 is positioned at bottom push rod 14.Movable insert 21 is connected with thimble panel 16 by spring 19, and can move around under the effect of oblique top guide rod 6 and spring 19.Movable insert 21 is provided with the movable accommodating hole 211 corresponding with fixing accommodating hole 201.
When movable accommodating hole 211 is overlapping with fixing accommodating hole 201, crowded bar 22 of cutting somebody's hair can enter fixing accommodating hole 201 by movable accommodating hole 211.
