For ease of understanding, fig. 1 shows a schematic view of a lip-shaped metal cover on an automobile heat shield in the present embodiment. It can be seen that the centre of the lid bottom is provided with a recess 41 and the side wall 42 is provided with an arcuate cut-out 43. If the conventional progressive die is used for punching, at least five processes of punching a bottom central groove, punching a cover side wall, punching a side wall opening, drawing an arc opening, trimming side wall end burrs and the like are required, the die is complicated, the condition that the plate is broken can be caused by two punching processes and at least one drawing process, and the yield of production is low.

The utility model discloses a set up the structure that a plurality of drifts 20 and upper stripper 30 match on upper die base 10, and set up the first lower bolster 61 and the second lower bolster 62 of matching on lower die base 50, and set up lower bolster 110 at the lower extreme of first lower bolster 61, can successively accomplish the lateral wall 42 die-cut to panel in the punching press in-process of once, draw and the shaping action of bottom recess 41, greatly reduced the manufacturing cost of mould not only, and obviously promoted the production efficiency of mould, and reduce phenomenons such as fracture and dimensional deviation that the sheet material caused because of stress accumulation in many punching press/die-cut in-process, improve the yields of product.

Specifically, the lower end of each punch 20 is located in the same plane, and the height of each punch is greater than the height of the upper stripper plate 30.

Specifically, the upper die base 10 is further provided with two or more second limiting members 90 at the sides of the plurality of punches 20, and the lower die 300 is provided with a plurality of third limiting members 100 adapted to the second limiting members 90 one by one.

In the present embodiment, the second limiting member 90 is disposed on the guide post of the upper mold 200, and the third limiting member 100 is disposed on the lower mold base 50.

Specifically, a lower backing plate 110 is further arranged on the lower die base 50 under the first lower die plate 61 in a matching manner, and the insert 70 is detachably and fixedly arranged on the lower backing plate 110.

Specifically, the lower mold 300 is further provided with a plurality of second elastic members 120, and each second elastic member 120 passes through and extends above the lower bolster plate 110 and the first lower mold plate 61 along the mold closing direction.

In this embodiment, the upper die base 10 is further provided at an upper end thereof with an upper pad plate 130 and an upper support plate 140, and the lower die base 50 is further provided at a lower end thereof with a lower pad 150 and a lower support plate 160.

The utility model discloses a working process as follows:

when the die is closed, the upper die 200 moves towards the lower die 300, the higher punches 20 firstly contact the sheet metal and bend the sheet metal downwards to form the side wall 42 of the metal cover, and the side wall 42 of the metal cover is formed by matching with the lower die plate on the lower die 300, wherein the three punches 20 are matched with the first lower die plate 61 to punch out the annular side wall 42, and the other punch 20 is matched with the second lower die plate 62 to punch out the arc-shaped notch 43 on the side wall 42; because the punch 20 and the upper stripper plate 30 have a height difference, after the side wall of the metal cover is in a shape of a side wall and is drawn for a certain height, the upper stripper plate 30 is in contact with the sheet, the first limiting piece 40 on the upper stripper plate is synchronously compressed, and a groove 41 is formed in the upper part of the sheet. Meanwhile, in the process of guiding the upper die and the lower die by the guide pillar, the second limiting part 90 on the guide pillar is matched with the third limiting part 100, the upper die 200 simultaneously compresses the first elastic part 80 and the second elastic part 120 on the lower die 300, the moving distance of the upper die 200 is limited, the dimensional accuracy of the groove 41, the side wall 42 and the arc-shaped notch 43 is ensured, and the product is prevented from being crushed.

When the mold is opened, the upper mold 200 is far away from the lower mold 300, and the punch 20 and the upper stripper plate 30 move up synchronously under the driving of the upper mold base 10. Since the first limiting member 40 is not stressed, remains still and slides relatively on the upper stripper plate 30, and the bottom end thereof abuts against the product, so as to avoid adhesion to the punch 20 and the upper stripper plate 30 or jump and bruise; meanwhile, the second elastic member 120 on the lower mold 300 is lifted up by the rebound force of the recovery deformation to lift the product body portion from the first lower mold plate 61; simultaneously, the first elastic element 80 bounces to jack the grooving part on the side wall of the product from the second lower template 62, so as to complete the die opening and stripping actions.

The above is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
