SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model aims to provide a mould through dividing into two sets of moulds of processing side turn-ups and tip crimp respectively, twice shaping has reduced the resilience volume of raw materials greatly, has improved production quality.

In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a mold, includes first mould and second mould, first mould includes first lower bolster, fixed mounting in first terrace die of first lower bolster upper end, cooperates the first die of punching press out the first die of side turn-ups and is used for installing the first cope match-plate pattern of first die with first terrace die, the second mould includes second lower bolster, fixed mounting in the second terrace die on the second lower bolster, cooperates the second die of punching press out tip turn-ups and is used for the second cope match-plate pattern of fixed second die with the second terrace die.

Through adopting above-mentioned technical scheme, put the raw materials to first terrace die on, first cope match-plate pattern descends and drives first die decline, pushes down raw materials both sides, forms the side turn-ups. And taking out the raw material with the side flanging, placing the raw material on a second male die, descending a second upper die plate to drive a second female die to descend, stressing the side flanging again, and simultaneously finishing the end flanging. The raw materials are molded twice in the processing process, so that the resilience of the side flanging and the end part flanging is reduced, and the quality of the workpiece is improved.

The utility model discloses a further set up to: a plurality of positioning nails are mounted on the upper surface of the first male die, and embedded grooves for the positioning nails to penetrate are formed in the lower surface of the first female die.

By adopting the technical scheme, the shapes of the first male die and the first female die are matched, and when the first male die is embedded in the first female die, a forming cavity for forming raw materials is formed between the first male die and the first female die. The first male die is provided with a positioning nail, and the first female die is provided with an embedding groove for embedding the positioning nail.
