Summary of the invention
For overcoming the defective of prior art, the technical problems to be solved in the utility model provided a kind of cover plate need not to dodge and take out product, plate compacted without impression subside, the enough thick Multilayer inclined wedge formula mould that is used for the punching press shaped negative angle structures of cover sheet thickness.
The technical solution of the utility model is: this Multilayer inclined wedge formula mould for the punching press shaped negative angle structures, it comprises the patrix holding pad, upper bolster, die shoe, the whole punch of side, the whole cutter piece of side, cover plate, the patrix holding pad is pressed on the cover board, the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, this mould also comprises the first patrix drive block, the first coaster, the second coaster, the patrix side guide, the first patrix drive block is connected to cover plate by the first coaster of forward translation, and the patrix side guide drives and be pressed in the whole punch of side top by being installed in the second supratrochlear nitrogen spring.
Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, thereby the top oblique in two limits of the piecemeal line of cover plate and the whole punch of side and negative angle, and cover plate is movable, take out again the whole punch of side so realized taking out first cover plate, so just can make cover plate need not to dodge and take out product; Owing to be provided with the patrix side guide, subside without impression so plate is compacted; Because the piecemeal line of cover plate and the whole punch of side is parallel with the facade of material returned mouth, so cover plate can be done enough thickly.
Description of drawings
