Abstract
The invention relates to a mold of components at lower part of an automobile side body inner plate. The mold consists of a lower mold part and an upper mold part, wherein the lower mold part comprises a lower mold base (7) and a convex mold core (5); the lower mold base (7) is arranged at the lowermost part of the mold; the convex mold core (5) is fixed on the upper surface of the lower mold base (7); the upper mold part comprises a nitrogen cylinder a (2), a nitrogen cylinder b (4), an upper mold pressing plate (3), an upper mold turning cutter block (6) and an upper mold base (1); the upper mold pressing plate (3) is fixed on the upper mold base (1) through a side pin; the upper mold turning cutter block (6) is arranged on the lower plane of the upper mold base (1) and is connected with the upper mold base (1); the nitrogen cylinder a (2) and the nitrogen cylinder b (4) are arranged in the middle of the upper mold pressing plate (3) and are fixed on the lower plane of the upper mold base (1); the upper mold base (1) is arranged at the uppermost part of the mold. Compared with the prior art, the mold has the advantages of simple structure, convenience in use, convenience in repairing, stable production and the like.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of vehicle side-wall inner-plate lower part mould.
Background technology
Current automobile market updates frequent, and R&D cycle and the market life of automobile are shorter and shorter, and this just proposes stern challenge to thereupon supporting component die.Vehicle side-wall inner-plate mainly comprises C post, D post, rear side window frame and lightening hole etc., is the important component part of automobile.
The existing mould for vehicle side-wall inner-plate part is divided into 2 operations, and want two jig frequencies during production, this not only needs a large amount of operating personnel, improves manufacturing cost high, and the manufacturing cycle is elongated, and production efficiency is not high.
In a lot of situation, trimming-punching die can produce vibrations and very large noise in process of production at present, shakes the life-span that use equipment and mould itself are shortened in conference greatly.Traditional holding pad elastic device uses elastomeric spring, fragile, makes troubles to the maintenance of mould.
Summary of the invention
Object of the present invention is exactly provide to overcome defect that above-mentioned prior art exists that a kind of easy to use, structure is simple, the vehicle side-wall inner-plate lower part mould of administration measure.
Object of the present invention can be achieved through the following technical solutions: a kind of vehicle side-wall inner-plate lower part mould, and this mould is made up of part of the lower die and part of the upper die;
Described part of the lower die comprises die shoe, punch insert, and described die shoe is arranged on the bottom of mould, and described punch insert is fixed on the upper surface of die shoe;
Described part of the upper die comprises nitrogen cylinder a, nitrogen cylinder b, patrix holding pad, patrix flange cutter block and upper bolster; Described patrix holding pad is fixed on upper bolster by side pin, described patrix flange cutter block is arranged at the lower plane of upper bolster and is attached thereto, described nitrogen cylinder a, nitrogen cylinder b are arranged on the middle part of patrix holding pad and are fixed on the lower plane of upper bolster, and described upper bolster is placed in the top of mould;
The elastic device that described patrix holding pad uses is nitrogen cylinder, and described nitrogen cylinder plays balanced action;
The nitrogen cylinder that described mould adopts has 8.
The motion principle of vehicle side-wall inner-plate lower part mould is: compressed by tablet by patrix holding pad when press is depressed with specified pressure, then does flange action by flange cutter block, and a punching press action is covered, and press rises part and takes out.
Compared with prior art, the present invention has the following advantages:
(1) long service life: employ nitrogen cylinder and reduce vibrations and the infringement that mould is caused of strong impulsive force as buffering.
(2) easy to maintenance: the maintenance of nitrogen cylinder is 6 months is its punching nitrogen; What avoid use spring is the frequent job costs changed.
(3) manufactured parts steady quality: nitrogen cylinder structure stress balance and pressure stability, thus steady quality when ensure that part is produced.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, a kind of vehicle side-wall inner-plate lower part mould, this mould is made up of part of the lower die and part of the upper die; Described part of the lower die comprises die shoe 7, punch insert 5, and described die shoe 7 is arranged on the bottom of mould, and described punch insert 5 is fixed on the upper surface of die shoe 7; Described part of the upper die comprises nitrogen cylinder a2, nitrogen cylinder b4, patrix holding pad 3, patrix flange cutter block 6 and upper bolster 1; Described patrix holding pad 3 is fixed on upper bolster 1 by side pin, described patrix flange cutter block 6 is arranged at the lower plane of upper bolster 1 and is attached thereto, described nitrogen cylinder a2, nitrogen cylinder b4 are arranged on the middle part of patrix holding pad 3 and are fixed on the lower plane of upper bolster 1, and described upper bolster 1 is placed in the top of mould; The elastic device that described patrix holding pad uses is nitrogen cylinder, and described nitrogen cylinder plays balanced action; The nitrogen cylinder that described mould adopts has 8.
The patrix holding pad elastic device of this vehicle side-wall inner-plate lower part mould uses nitrogen cylinder, and this reduces the noise that produces in mold work process and vibrations to a great extent, extends the service life of mould self, reduces use equipment damage.Bring conveniently to maintenance again.
Claims (3)
