Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1, 2, 3 and 4, the die wedge returning mechanism comprises a lower die assembly base 11, wherein a lower die base 1, a lower die 4 and a wedge die 7 are installed inside the lower die assembly base 11. The general base 11 of lower mould and the horizontal sliding connection of lower bolster 1, the downside of the general base 11 of lower mould is provided with the promotion module, specifically is cylinder 3, and the inside bottom of the general base 11 of lower mould is provided with cylinder mounting groove 12, and cylinder 3 installs in the inside of cylinder mounting groove 12, is connected with connecting plate 14 between the activity axle head of cylinder 3 and lower bolster 1. The lower die 4 is fixed on the upper side of the lower die holder 1, the air cylinder 3 can push the lower die holder 1 to move towards the left side, and meanwhile, the lower die 4 also moves synchronously.

The right-hand member of die holder 1 is provided with the boosting module, and the boosting module includes two inclined pushing surfaces 2, and the right-hand member of die holder 1 is provided with two fixed columns, and two inclined pushing surfaces 2 set up respectively at two fixed capital portions, and wherein, go up the mould and be provided with the inclined plane rather than correspondingly, push die holder 1 to the left side through the extrusion force about between the inclined plane when last mould pushes down, make it be close to slide wedge mould 7.

As shown in fig. 1, a lower die inclined plane 6 is arranged on the left end surface of the lower die 4, a lower die base inclined plane 5 is arranged on the left end surface of the lower die base 1, the lower die inclined plane 6 and the lower die base inclined plane 5 form an included angle, the right end of the wedge die 7 is correspondingly set to be in a shape matched with the included angle, two wedge surfaces are arranged on the upper surface and the lower surface of the right end of the wedge die 7, and the two wedge surfaces are respectively attached to the lower die base inclined plane 5 and the lower die inclined plane 6. The wedge die 7 is matched with the lower die 4, and the wedge die and the lower die are contacted to form a complete lower die.

The inclined wedge die 7 is further provided with an inclined wedge die inclined surface 9, an inclined sliding surface 13 is arranged on one inner side surface of the lower die assembly base 11, and the inclined wedge die inclined surface 9 is in sliding connection with the inclined sliding surface 13, namely the inclined wedge die 7 is in sliding connection with the lower die assembly base 11.

And a spring is arranged between the wedge die 7 and the lower die assembly base 11, and the thrust direction of the spring is consistent with the sliding direction of the inclined plane 9 of the wedge die. When the slide wedge mould 7 did not contact with die holder 1 and lower mould 4 promptly, slide wedge mould 7 was pushed to the right side below under the effect of spring force, the whole height of slide wedge mould 7 was less than the height of lower mould 4 this moment, when die holder 1 and lower mould 4 were pushed to the left side, the slide wedge face contact of lower bolster inclined plane 5 and slide wedge mould 7 right downside, and both sliding connection under thrust, it moves to promote slide wedge mould 7 upper left, the spring shrink, finally slide wedge mould 7 blocks between lower mould inclined plane 6 and die holder inclined plane 5, slide wedge mould 7 and die holder 1 butt this moment.

The bottom of the lower die holder 1 is provided with a guide chute 10, the guide chute 10 penetrates through the lower die assembly base 11 and extends to the outside, and the waste materials fall into the guide chute 10 after being cut in the die pressing process and are conveyed to the outside under the action of gravity.

The working principle is as follows: under the initial state, lower die holder 1 and slide wedge mould 7 contactless, when the upper die pushed down, the inclined plane that corresponds to setting up on the upper die contacted with tapered push surface 2 to extrude it left, push lower die holder 1 to the left side, make it be close to slide wedge mould 7, lower die holder inclined plane 5 and the slide wedge face contact of slide wedge mould 7 right downside, and under thrust effect both sliding connection, promote slide wedge mould 7 and upper left side and remove, the spring shrink, finally slide wedge mould 7 card is gone into between lower mould inclined plane 6 and lower die holder inclined plane 5. After the pressing die is completed, the upper die is lifted, then the air cylinder 3 pushes the connecting plate 14 to move rightwards, the lower die holder 1 and the lower die 4 are pushed to move rightwards, the inclined wedge die 7 is pushed to the right lower side by the spring at the moment, so that the product 8 is separated from the inclined wedge die 7, the main function is that the upper side of the notch 15 on the product 8 is not shielded any more, and the product 8 can be directly taken out upwards conveniently.
