The specific embodiment

Below in conjunction with accompanying drawing, provide preferred embodiment of the present utility model, and be described in detail.

Comprise cover half 14 and slide block 1 according to composite die of the present utility model mechanism, this cover half 14 is connected by Angle Pin 15 with this slide block 1, as shown in Figure 2.Particularly, an end of this Angle Pin 15 is fixed by screws on cover half 14, and the relevant position of slide block 1 has through hole, and Angle Pin 15 passes slide block in this through hole, thereby limits the relative position relation of these cover half 14 and slide block 1 by Angle Pin 15.

Slide block 1 comprises slide block body 16 and cover plate 13, and this cover plate 13 is fixedly connected with by screw with slide block body 16, limits a cavity 17 between this cover plate 13 and slide block body 16.Be provided with a push pedal 2 in this cavity 17, this push pedal 2 can be in the interior reciprocating motion of this cavity 17.One guide pillar 5 runs through this push pedal 2 and extends, and an one end is fixed on cover plate 13, and another end is fixed on slide block body 16.The relevant position of push pedal 2 has through hole, and guide pillar 5 passes push pedal 2 at this through hole place.Guide pillar 5 is provided with guide pin bushing 11 and check ring 12 in this through hole, and guide pillar 5 passes guide pin bushing 11, thereby guides and guarantee the direction of motion of push pedal 2 in cavity 17, and this check ring 12 can prevent that guide pin bushing 11 from skidding off from through hole.In addition, between push pedal 2 and cover plate 13, be provided with spring 7, an end of this spring 7 is fixed in cover plate 13, and the other end is fixed in push pedal 2.The inside of slide block 1 is provided with the pitched roof mechanism be comprised of tilted footstock 8, angle ejector rod 9 and oblique top 4, and wherein, tilted footstock 8 is fixed in push pedal 2, and oblique top 4 is corresponding to the specific position for the treatment of demoulding product 10.This pitched roof mechanism is mechanism common in this area, and structure and the mechanism of action that it is concrete do not repeat them here.Facing on the surface of slide block body 16 of push pedal 2 is provided with push pedal limited block 6, thereby guarantees the relative distance between push pedal 2 and slide block body 16, avoids push pedal 2 to contact with the large-area of slide block body 16 simultaneously.

There is cover half block 3 on cover half 14, as Fig. 3-as shown in 4.Because this cover half block 3 is fixed on cover half 14, therefore can only move along with the direction of cover half along the folding mould, move on the direction perpendicular to the paper of Fig. 3 and Fig. 4, be all motionless with respect to the X indicated in figure, Y-direction, thereby play a part spacing to push pedal 2.

According to motion principle and the step of composite die of the present utility model mechanism, be summarized as follows:

One, die sinking:

1, as shown in Figure 3, under the state of matched moulds, slide block 1 moves along+Y-direction under the effect of Angle Pin 15, it is motionless that push pedal 2 keeps under the effect of spring 7 and cover half block 3, the oblique top 4 of pitched roof mechanism is stretched out (moving along-Y-direction with respect to slide block 1) from slide block 1, by the different incline direction of Angle Pin 9, can realize oblique top 4+X or-motion of loosing core on directions X.

When 2, the movement travel of slide block 1 reaches S, push pedal limited block 6 contacts with slide block body 16, push pedal 2 drives pitched roof mechanisms and slide block 1 and is synchronized with the movement along+Y-direction, until composite die of the present utility model mechanism throws off product fully, completes all de-barbs move (Fig. 4) at the back-off of+Y-direction.

Two, matched moulds:

1, as shown in Figure 4, under die opening state, slide block 1 starts to reset along-Y-direction under the effect of Angle Pin 15, and push pedal 2 drives whole pitched roof mechanism and is synchronized with the movement with slide block body 1 under spring 7 effects.

2, push pedal 2 runs into the rear stop motion of cover half block 3, and slide block 1 continues to do reseting movement under Angle Pin 15 drives, and drives oblique top 4 simultaneously and resets, until composite die of the present utility model mechanism resets fully, matched moulds completes (as Fig. 3).

Above-described, be only preferred embodiment of the present utility model, not in order to limit scope of the present utility model, above-described embodiment of the present utility model can also make a variety of changes.Be that simple, the equivalence that every claims according to the utility model application and description are done changes and modify, all fall into the claim protection domain of the utility model patent.The utility model not detailed description be the routine techniques content.
