Description

A kind of mould for car rear cover hinge reinforcing plate part
Technical field
This utility model relates to a kind of auto parts mould, especially relates to a kind of for car rear cover hinge reinforcing plate zero The mould of part.
Background technology
Car rear cover hinge reinforcing plate is as the indispensable part of body of a motor car, and the stability of its quality is for automobile Safety plays particularly important effect.Up till now mould be divided into four operations, want four jig frequencies during production, need substantial amounts of behaviour Making personnel, production efficiency is the highest, and part quality is not sufficiently stable.
Summary of the invention
Defect that the purpose of this utility model is contemplated to overcome above-mentioned prior art to exist and a kind of production cost is provided Low, easy to maintenance, the safe and reliable mould for car rear cover hinge reinforcing plate part.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of mould for car rear cover hinge reinforcing plate part, including lower mold assemblies and upper die component, this mould is Combination die continuously,
Described lower mold assemblies includes die shoe, lower mold holding pad and is successively set on die shoe along material strip feedstock direction Drawing punch, edge-cutting and hole-punching punch, flanging and restriking punch and punching separation punch,
Described upper die component includes upper bolster, upper mold holding pad and is arranged on upper bolster and mates with lower mold assemblies Drawing die, edge-cutting and hole-punching die, flanging and restriking die and punching separation die,
Described upper die component and lower mold assemblies, by a matched moulds, complete to draw car rear cover hinge reinforcing plate part Prolong, edge-cutting and hole-punching, flanging and restriking and punching separate.
The edge of described drawing punch is provided with the blank holder matched with drawing die.
Upper mold eccentric swage and lower mold ejector, described upper mold is further respectively had on described upper die component and lower mold assemblies Eccentric swage and lower mold ejector are push rod structure.
Being additionally provided with upper mold insert on described upper die component, described upper mold insert is at upper die component and lower mold assemblies matched moulds Shi Jinhang positions.
Described lower mold assemblies also includes that blanking cutter block, described blanking cutter block are arranged on die shoe.
Described lower mold assemblies also includes bar in multiple lower mold, and in described lower mold, bar is arranged on the lower surface of die shoe, Being provided with reject chute in lower mold between bar, described reject chute is arranged on the lower section of blanking cutter block.
Drawing, edge-cutting and hole-punching, flanging and restriking, punching are separated four combination of actions together by this mould, have just become continuous Four traditional achievable parts of operation are completed by combination die with a secondary mould, and centre eliminates three jig frequencies, reduces Production cost, improves the stability that part produces.
With the motion principle of mold, material strip is compressed by upper eccentric swage when press is depressed with specified pressure, then Being done drawing, edge-cutting and hole-punching, flanging and restriking, punching separating action respectively by the working portion of four stations, a punching press action is walked Complete.
Owing to the car rear cover hinge reinforcing plate parts modeling degree of depth is big, it is impossible to straight forming, therefore drawing structure is taked to replace Molding structure, is coordinated with die and punch from blank holder, reaches to stretch purpose.
In drawing process, blank holder drives product to move up and down, and for avoiding material strip to rupture, affects feeding smooth and easy, causes Potential safety hazard, therefore lead material strip by described in the linking i.e. of product and material strip, it is shaped to bending, improves and lead material strip length, can be effective Avoid the problems referred to above.
Compared with prior art, this utility model has the advantages that
Production cost is low: omitting three secondary moulds, few three jig frequencies, lathe and personnel save;
Easy to maintenance, safe and reliable: upper eccentric swage uses upper push rod structure, use spring as power source, conveniently keep in repair, Need not give birth to prenatal diagnosis every time or change binder power source.
Accompanying drawing explanation
Fig. 1 is that master of the present utility model regards cross-sectional view;
Fig. 2 is that the master of drawing punch of the present utility model and drawing die regards cross-sectional view.
In figure, 1 is bar in lower mold, and 2 is lower mold holding pad, and 3 is blanking cutter block, and 4 is upper mold eccentric swage, and 5 is drawing punch, 6 is drawing die, and 7 is edge-cutting and hole-punching punch, and 8 is edge-cutting and hole-punching die, and 9 is flanging and restriking punch, and 10 is flanging and restriking die, 11 is punching separation punch, and 12 is punching separation die, and 13 is reject chute, and 14 is blank holder.
Detailed description of the invention
With specific embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Embodiment 1
A kind of mould for car rear cover hinge reinforcing plate part, as shown in Fig. 1~2, including lower mold assemblies and upper mold Assembly, this mould is continuous combination die, and wherein, lower mold assemblies includes die shoe, lower mold holding pad 2 and depends on along material strip feedstock direction Secondary drawing punch 5, edge-cutting and hole-punching punch 7, flanging and restriking punch 9 and the punching separation punch 11 being arranged on die shoe, described Upper die component include upper bolster, upper mold holding pad and be arranged on upper bolster and mate with lower mold assemblies drawing die 6, cut Limit punching concave die 8, flanging and restriking die 10 and punching separation die 12, upper die component and lower mold assemblies pass through a matched moulds, complete The drawing of car rear cover hinge reinforcing plate part in pairs, edge-cutting and hole-punching, flanging and restriking and punching separate.The edge of drawing punch 5 It is provided with the blank holder 14 matched with drawing die 6.Further respectively have on upper die component and lower mold assemblies upper mold eccentric swage 4 and under Mould ejector, upper mold eccentric swage 4 and lower mold ejector are push rod structure.Being additionally provided with upper mold insert on upper die component, upper mold is inlayed Block positions when upper die component is with lower mold assemblies matched moulds.Lower mold assemblies also includes bar 1 in blanking cutter block 3 and multiple lower mold, Blanking cutter block is arranged on die shoe, and in lower mold, bar 1 is arranged on the lower surface of die shoe, is provided with reject chute in lower mold between bar 1 13, reject chute 13 is arranged on the lower section of blanking cutter block 3.
