Abstract

The utility model discloses a drawing die with an upper movable material pressing core and a lower movable material pressing core. The drawing die comprises an upper die base (1), an upper female die (2), a lower die base (4), a lower die edge pressing ring (5) and a lower male die (6). The upper movable material pressing core (3) is arranged in the region, corresponding to the position outside an upper movable material pressing core parting line of an automobile covering part, of the upper die base (1). The lower movable material pressing core (7) is arranged in the region, corresponding to the position inside a lower movable material pressing core parting line of the automobile covering part, of the lower die base (4). The drawing die with the upper movable material pressing core and the lower movable material pressing core can improve distribution and flow of local materials and finally improve the quality of plate parts and reduce the die debugging cost.

Description

A kind of drawing die with up and down material pressing core
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of drawing die that belongs to vehicle cladding element punching.
Background technology
Automobile panel is complex-shaped, and moulding difficulty is large.Some covering is if luggage case inner panel is because its interior shape is very complicated, and as Fig. 1,9 represent blank line, 10 represent die parting line, and 11 represent upper movable material pressing core die parting line, and 12 represent lower movable material pressing core die parting line, in forming process, complicated shape place wrinkling is comparatively serious, and moulding is very difficult.Conventional way is change plate material, uses the better material of processability; But the change of part material increases undoubtedly cost and has reduced part strength.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of quality of improving the distribution of local material and flow, finally improve plate, reduces the drawing die with up and down material pressing core of die debugging cost.
In order to solve the problems of the technologies described above, the drawing die with up and down material pressing core that the utility model provides, comprise upper bolster, upper cavity die, die shoe, counterdie blank holder and lower punch, on described upper bolster, be provided with movable material pressing core for the region beyond the upper movable material pressing core die parting line of automobile panel, on described die shoe, be provided with lower movable material pressing core corresponding to the region in the lower movable material pressing core die parting line of automobile panel.
Described upper movable material pressing core and lower movable material pressing core stroke are 45mm, and described counterdie blank holder stroke is 75mm.
Described upper bolster and described die shoe are provided with guiding parts.
Adopt the drawing die with up and down material pressing core of technique scheme, region beyond upper movable material pressing core die parting line need make movable material pressing core, lower movable material pressing core die parting line need be made lower movable material pressing core with interior region, up and down material pressing core is arranged to different strokes and active force, active force derives from lathe pneumatic jack bar, controlled motion order, realizes part moulding in advance.Upper movable material pressing core and lower movable material pressing core stroke are 45mm, and counterdie blank holder stroke is 75mm.Lathe top shoe drives upper bolster to move downward because movable material pressing core in travel relationships and counterdie blank holder contact at first and plate is pushed down to drawing starts, upper bolster continues down to move 75mm, this at present movable material pressing core start to contact with upper cavity die, counterdie blank holder moves to the end, and part is moulding in advance.Upper bolster continues down motion, now goes up movable material pressing core and is subject to counterdie blank holder to limit and remain static on earth, and upper cavity die moves downward, and lower movable material pressing core is subject to upper cavity die driving to start down to move 45mm, and mould is completely closed, and drawing completes.In order to ensure mould and die accuracy, Design of Dies guiding parts guiding.
The utility model has considered to add up and down material pressing core in drawing die.In the time that drawing die die goes downwards to predetermined stroke, up and down material pressing core starts to contact plate, and part is moulding in advance, by locally-shaped difficulty, the moulding in advance of wrinkling serious cracking place, improve the distribution of local material and flow, finally improving the quality of plate, reducing die debugging cost.
Advantage and the good effect of invention:
The utility model advantage is to solve preferably the serious wrinkling problem in forming process, indirectly reduces cracking risk, thereby has reduced die debugging cost.
In sum, the utility model is the drawing die with up and down material pressing core of a kind of quality of improving the distribution of local material and flow, finally improve plate, minimizing die debugging cost.
Brief description of the drawings
Fig. 1 is automobile panel shape figure.
Fig. 2 is upper die structure schematic diagram.
Fig. 3 is lower die structure schematic diagram.
Fig. 4 is that movable material pressing core of the present utility model starts to contact schematic diagram with counterdie blank holder.
Fig. 5 is that upper cavity die of the present utility model starts to contact schematic diagram with lower movable material pressing core.
Fig. 6 is that the utility model is drawn into end view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to Fig. 1, Fig. 2 and Fig. 3, upper bolster 1 is provided with upper cavity die 2, die shoe 4 is provided with counterdie blank holder 5 and lower punch 6, on upper bolster 1, be provided with movable material pressing core 3 for the region beyond the upper movable material pressing core die parting line of automobile panel, on die shoe 4, be provided with lower movable material pressing core 7 corresponding to the region in the lower movable material pressing core die parting line of automobile panel, upper movable material pressing core 3 and lower movable material pressing core 7 strokes are 45mm, counterdie blank holder 5 strokes are 75mm, and upper bolster 1 is provided with guiding parts 8 with described die shoe 4.
Referring to Fig. 1, Fig. 2 and Fig. 3, region beyond upper movable material pressing core die parting line 11 need make movable material pressing core 3, lower movable material pressing core die parting line 12 need be made lower movable material pressing core 7 with interior region, up and down material pressing core is arranged to different strokes and active force, active force derives from lathe pneumatic jack bar, controlled motion order, realizes part moulding in advance.Upper movable material pressing core 3 and lower movable material pressing core 7 strokes are 45mm, and counterdie blank holder 5 strokes are 75mm.Lathe top shoe drives upper bolster 1 to move downward because movable material pressing core 3 in travel relationships and counterdie blank holder 5 contact at first and plate is pushed down to drawing starts (Fig. 4), upper bolster 1 continues down to move 75mm, this at present movable material pressing core 7 start to contact with upper cavity die 2, counterdie blank holder 5 moves to the end, part moulding in advance (Fig. 5).Upper bolster 1 continues down to move, now go up movable material pressing core 3 and be subject to counterdie blank holder 5 to limit and remain static on earth, upper cavity die 2 moves downward, and lower movable material pressing core 7 is subject to upper cavity die 2 drivings to start down to move 45mm, mould is completely closed, and drawing completes (Fig. 6).In order to ensure mould and die accuracy, Design of Dies guiding parts 8 lead.
