The mould having many automotive hinge reinforcing plate parts at present is all single overturning process, punching operation and separates work Sequence, had the most both added punching press jig frequency, and had occupied more storage space, caused the waste in space, place, with Time the stability of part quality also can be affected.
Chinese patent CN203725608U discloses the mould of a kind of automotive hinge reinforcing plate part, including upper mold And lower mold, described lower mold is arranged at below upper mold, and described upper mold includes cope match-plate pattern, the upper bolster being sequentially connected with And upper mold core, described lower mold includes lower bolster, die shoe and the lower mold core being sequentially connected with, in described upper mold core It is sequentially installed with flange cutter block, separating knife block and drift, described lower mold core is sequentially installed with flange die, divides From die and stamping cavity die, described flange die is correspondingly arranged with flange cutter block, described separation die with separate Cutter block is correspondingly arranged, and described stamping cavity die is correspondingly arranged with drift, and this utility model has production efficiency height, becomes This advantage such as the lowest, but the mould of this patent cannot avoid turning over the part plucking during right-angle side, flange resilience, with And be difficult to eject and cause the problems such as material strip card pauses.
Summary of the invention
The purpose of the present invention is contemplated to solve the problems referred to above and provide a kind of production cost low, easy to maintenance and peace The mould of full automotive hinge reinforcing plate part reliably.
The purpose of the present invention can be achieved through the following technical solutions:
The mould of a kind of automotive hinge reinforcing plate part, including upper die and lower die, described lower mold is located under upper mold Side, described lower mold includes die shoe and the lower holding pad, molding concave die and the reject chute that are located on die shoe, institute The upper mold stated includes upper bolster and the blanking cutter block being located on upper bolster and forming convax mould, described molding concave die with Forming convax mould is correspondingly arranged,
Described forming convax mould includes that pre-flanging die and flanging die, described molding concave die include rollover edge die It is provided with pre-flange cutter block, flanging die and flange die with flange die, pre-flanging die and rollover edge die both sides Both sides are provided with flange cutter block,
During work, upper bolster presses to die shoe, is compressed by part to be processed, described blanking cutter block and lower binder version Having coordinated trimming operation, described pre-flange cutter block completes rollover under pre-flanging die and rollover edge die coordinate Limit operation, described flange cutter block completes overturning process under flanging die and flange die coordinate.
Described pre-flange cutter block is 70-80 ° with the angle of pre-flanging die.
Described flange cutter block is 90 ° with the angle of flanging die.
This mould connects the press driving upper mold motion.
Described lower mold both sides are provided with the guide pillar for guiding upper mold to move.
Described lower mold is provided with bar in lower mold.
Described upper mold is provided with bar in upper mold.
Described upper mold is provided with upper mold insert.
Described upper mold is provided with eccentric swage, and described upper eccentric swage uses upper push rod structure.
Compared with prior art, the part quality that the present invention produces is high, and the present invention arranges pre-overturning process, flange Operation is divided into two steps, the pre-flange of the first step, first routs up substantially flange moulding, discharges stress, then carries out second step, The part anglec of rotation is put so that overturning process becomes molding procedure, reach to turn over right-angle side effect, be prevented effectively from Turn over the part plucking during right-angle side, flange resilience, and be difficult to eject and cause the problems such as material strip card pauses;This Outward, the present invention is easy to maintenance, and upper eccentric swage uses the convenient maintenance of upper push rod structure, it is not necessary to give birth to prenatal diagnosis every time Or change binder power source.

Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment 1
The mould of a kind of automotive hinge reinforcing plate part, as Figure 1-3, this mould includes its structural representation Mould and lower mold, lower mold is located at the lower section of upper mold, and lower mold includes the die shoe 8 being sequentially connected with, lower holding pad 2, becomes Type die 5 and reject chute 7, upper mold includes the upper bolster 9 being sequentially connected with, upper holding pad, blanking cutter block 3 and becomes Type punch 6, forming convax mould 6 is correspondingly arranged with molding concave die 5.
Forming convax mould includes pre-flanging die 15 and flanging die 12, and molding concave die includes rollover edge die 16 He Flange die 13, pre-flanging die 15 and rollover edge die 16 both sides are provided with pre-flange cutter block 14, flanging die 12 and flange die 13 both sides be provided with flange cutter block 11, pre-flange cutter block 14 with the angle of pre-flanging die 12 is 70 °, flange cutter block 11 is 90 ° with the angle of flanging die 12, and lower mold both sides are additionally provided with for guiding upper mold The guide pillar 10 of motion, lower mold is additionally provided with bar 1 in lower mold, upper mold is additionally provided with bar 4 in upper mold, upper mold also sets Having upper mold insert and upper eccentric swage, upper eccentric swage uses upper push rod structure.
During work, mould connects the press driving upper mold motion, when press is depressed with specified pressure, and upper bolster Pressing to die shoe, compressed by part to be processed, blanking cutter block 3 has coordinated trimming operation with lower binder version 2, in advance Flange cutter block 14 completes pre-overturning process, flange cutter block under pre-flanging die 15 and rollover edge die 16 coordinate 11 complete overturning process under flanging die 12 and flange die 13 coordinate.
Owing to this parts modeling is complicated, flange angle is big, therefore flanging process is divided into two steps, and the first step is pre-flange, Rout up substantially flange moulding, discharge stress, then carry out second step, the part anglec of rotation is put so that flange work Sequence becomes molding procedure, reaches to turn over right-angle side effect, effectively prevent and turns over part plucking during right-angle side, flange Resilience, and be difficult to eject and cause the problems such as material strip card pauses.
