Description

A kind of continuous production mould of automobile rear floor reinforcing plate part
Technical field
The present invention relates to a kind of continuous production mould, more particularly, to a kind of continuous production of floor reinforcing plate part after vapour Mould.
Background technology
Floor reinforcing plate is as an important component on body of a motor car, the intensity and quality of rear floor reinforcing plate afterwards The quality of automobile rear Strength Safety is directly affects, the production stability of rear floor reinforcing plate is most important.It is many at present In the case of traditional moulds in process of production punching press once can only the operation part of punching one and half, increase cost of stamping.Personnel grasp Potential safety hazard during work be present, and to punching parts because the maloperation of people causes part quality problem.
Chinese patent CN104001799A discloses a kind of double acting mould of vehicle right and left tail-gate reinforcing plate, is related to zero, automobile Part manufacturing technology field;Including lower template and cope plate provided with ejection hole, lower template is provided with cavity plate, and cavity plate inner chamber is provided with and moved back Expect core;Cope plate is provided with punch-pin, and the outside of punch-pin is provided with upper molding flange, and upper molding flange is connected by screw and cope plate Connect, be set with spring on screw, but mould insufficient strength when friction feeding produces.
The content of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind realize steady feeding, Service life is long, the continuous production mould of automobile rear floor reinforcing plate part easy to maintenance.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of continuous production mould of automobile rear floor reinforcing plate part, is made up of part of the lower die and part of the upper die,
Described part of the lower die includes die shoe and the stamping cavity die knife being connected on die shoe, lower mould edge iron, led Post guide pin bushing, described part of the upper die include upper bolster and the holding pad, drift, the upper mould edge iron that are connected on upper bolster,
Also include feeding belt, the end of the feeding belt stamps out a boss, and the boss is radially arranged along feeding belt.
The height of described boss is identical with the thickness of feeding belt.
Described stamping cavity die knife, lower mould edge iron are fixed on the upper surface of die shoe, and described guide pillar guide pin bushing is set In the corner of die shoe.
Described lower mould edge iron is insert structure, and detachable connection is on die shoe.
Described holding pad, drift, upper mould edge iron are fixed on the lower surface of upper bolster, and described holding pad is arranged at The middle and lower part of upper mould edge iron is simultaneously connected with upper mould edge iron, and drift is arranged at the middle part of molding flitch;The corner of upper bolster Provided with the guide pillar to match with die shoe.
Described upper mould edge iron is insert structure, and detachable connection is on upper bolster.
Compared with prior art, the present invention has advantages below:
(1) convex closure is stamped out on feeding belt, convex closure is played a part of being similar to bead either part Moulding, can steady feeding to improve material strip intensity;
(2) service life is grown:All deburrings use insert form.The service life of mould itself is extended, is reduced Infringement and consume to production equipment;
(3) it is easy to maintenance:Using insert structure, do not have to again take whole mold hoisting to maintenance sites big in maintenance The place of amount, only the insert to need repairing need to be pulled down and can repaired.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the structural representation of feeding belt;
Fig. 3 is the partial structural diagram of projection section.
In figure, mould edge iron, 4- upper bolsters, 5- holding pads, 6- drifts, 7- are led under 1- die shoes, 2- stamping cavity dies knife, 3- Post, 8- feeding belts, 9- boss.
Embodiment
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
A kind of continuous production mould of automobile rear floor reinforcing plate part, its structure is as shown in figure 1, mainly by part of the lower die And part of the upper die composition, part of the lower die include die shoe 1 and the stamping cavity die knife 2, the lower mould edge iron that are connected on die shoe 1 3 and guide pillar guide pin bushing, wherein stamping cavity die knife 2, lower mould edge iron 3 be fixed on the upper surface of die shoe 1, guide pillar guide pin bushing is arranged on The corner of die shoe, lower mould edge iron 3 is insert structure, and detachable connection is on die shoe.Part of the upper die includes upper bolster 4 And holding pad 5, drift, upper mould edge iron, guide pillar 7 on upper bolster 4 are connected to, holding pad 5, drift 6, upper mould edge iron are consolidated Due on the lower surface of upper bolster 4, wherein, holding pad 5 is arranged at the middle and lower part of mould edge iron and is connected with upper mould edge iron, Drift 6 is arranged at the middle part of molding flitch;The corner of upper bolster 4 is provided with the guide pillar 7 to match with die shoe, upper mould edge iron For insert structure, detachable connection is on upper bolster 4.
In addition, in addition to feeding belt 8, the end of the feeding belt 8 stamp out a boss 9, and the boss 9 is along feeding belt Be radially arranged, the height of boss 9 is identical with the thickness of feeding belt 8.Because the mould of the present invention produces automatically for full process, send The stabilization of material just seems critically important.Because the part is complicated, process is more so that and material strip is grown, and because the problem of stock utilization, It is small to take material width.Thus can not steady feeding.So considering from technological angle, a boss 9 is stamped out on feeding belt 8, Boss 9 is played a part of being similar to bead either parts modeling, to improve material strip intensity, is steadily sent so as to realize Material.
