Abstract
The utility model relates to a die for lower parts of inner plates of an automobile side body. The die is formed by a lower die part and an upper die part, the lower die part comprises a lower die base (7) and a male die core (5). The lower die base (7) is arranged on the bottom part of the die, and the male die core (5) is fixed on the upper surface of the lower die base (7). The upper die part comprises a nitrogen cylinder a (2), a nitrogen cylinder b (4), an upper die holding plate (3), an upper turnup tool block (6) and an upper die base (1). The upper die holding plate (3) is fixed on the upper die base (1) through a side pin, the upper turnup tool block (6) is arranged on and connected to the lower plane of the upper die base (1), the nitrogen cylinder a (2) and the nitrogen cylinder b (4) are arranged in the middle of the upper die holding plate (3) and are fixed on the lower plane of the upper die base (1), and the upper die base (1) is arranged on the top part of the die. Compared with the prior art, the die for the lower parts of the inner plates of the automobile side body has the advantages of being simple in structure, convenient to use and maintain, stable in production and the like.
Description
Technical field
The utility model relates to a kind of mould, especially relates 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 has just proposed 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, wants two jig frequencies during production, and this not only needs a large amount of operating personnel, has improved manufacturing cost high, and the manufacturing cycle is elongated, and production efficiency is not high.
In at present a lot of situations, trimming-punching die can produce vibrations and very large noise in process of production, shakes the life-span that use equipment and mould itself are shortened in conference greatly.Traditional holding pad elastic device is used elastomeric spring, fragile, makes troubles to the maintenance of mould.
Summary of the invention
The purpose of this utility model be exactly in order to overcome the defect that above-mentioned prior art exists, provide a kind of easy to use, simple in structure, produce stable vehicle side-wall inner-plate lower part mould.
The purpose of this utility model can be achieved through the following technical solutions: a kind of vehicle side-wall inner-plate lower part mould, and this mould is comprised 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 below 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 piece and upper bolster; Described patrix holding pad is fixed on upper bolster by side pin, described patrix flange cutter piece 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 is used 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: when press is depressed with specified pressure, by patrix holding pad, tablet is compressed, then by flange cutter piece, do flange and move, a punching press action is covered, and press rises part and takes out.
Compared with prior art, the utlity model has following advantage:
(1) long service life: used nitrogen cylinder to reduce the infringement shaking and strong impulsive force causes mould as buffering.
(2) easy to maintenance: the maintenance of nitrogen cylinder is within 6 months, to be a nitrogen of its punching; What avoided use spring is the frequent job costs of changing.
(3) manufactured parts steady quality: nitrogen cylinder structure stress balance and pressure stability, thereby the steady quality while having guaranteed part production.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of vehicle side-wall inner-plate lower part mould, this mould is comprised 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 below 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 piece 6 and upper bolster 1; Described patrix holding pad 3 is fixed on upper bolster 1 by side pin, described patrix flange cutter piece 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 is used is nitrogen cylinder, and described nitrogen cylinder plays balanced action; The nitrogen cylinder that described mould adopts has 8.
What the patrix holding pad elastic device of this vehicle side-wall inner-plate lower part mould was used is nitrogen cylinder, and this reduces the noise and the vibrations that in mold work process, produce to a great extent, has extended the service life of mould self, has reduced using equipment damage.To maintenance, brought convenience again.
