Abstract

The utility model relates to a mould for a lower reinforcing plate component of a column A of an automobile. The mould comprises an upper mould assembly and a lower mould assembly, wherein the upper mould assembly comprises an upper mould holder as well as an upper mould core, an upper mould insert and an upper mould material presser arranged on the upper mould holder, and the upper mould core is located below the upper mould holder; the lower mould assembly comprises a lower mould holder as well as a lower mould core and a material ejector arranged on the lower mould holder, and the lower mould core is located above the lower mould holder; the upper mould assembly further comprises a plurality of upper ejection rods, the upper ejection rods penetrate through the upper mould holder and are connected against the top of the upper mould core; a trimming-punching concave mould, a flanging-shaping concave mould and a lateral punching concave mould are arranged on the upper mould core; and a trimming-punching convex mould, a flanging-shaping convex mould and a lateral punching convex mould are arranged on the lower mould core. Compared with the prior art, three moulds are integrated in one mould according to the utility model, thus the production procedures are reduced; and moreover, the structure of the upper ejection rod is used, so that the mould is convenient to maintain, and a material-pressing power source does not need to be checked or replaced before production each time.

Description

Automobile A column lower reinforcing plate component die
Technical field
The utility model relates to a kind of mould, especially relates to a kind of automobile A column lower reinforcing plate component die.
Background technology
In the prior art, processing is used for automobile A column lower reinforcing plate part and is divided into 3 operations, use three auxiliary process moulds, needs a large amount of operating personnel, and manufacturing cost is high, and the manufacturing cycle is long, and production efficiency is not high.As power source, spring or nitrogen spring all can have require the maintenance and the renewal cost in the production process of normal damage and periodic replacement to promote significantly to eccentric swage with spring or nitrogen spring.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence a kind of automobile A column lower reinforcing plate component die that can the three process in trimming and piercing die, flanging and restriking and side blow hole be carried out simultaneously to be provided.
The purpose of the utility model can realize through following technical scheme:
A kind of automobile A column lower reinforcing plate component die; Comprise upper die component and following membrane module; Described upper die component comprises upper bolster and is arranged on that upper mold core, patrix on the upper bolster inserted, the patrix eccentric swage; Described upper mold core is positioned at the below of upper bolster, and described membrane module down comprises die shoe and be arranged on lower mold core and the ejector on the die shoe that described lower mold core is positioned at the top of die shoe; Described upper die component also comprises a plurality of upper ejector pins; This upper ejector pin passes the top that upper bolster is connected to upper mold core, and described upper mold core is provided with trimming and piercing die die, flanging and restriking die and side blow hole die, and described lower mold core is provided with trimming and piercing die punch, flanging and restriking punch and the side blow hole punch with trimming and piercing die die, flanging and restriking die and side blow hole die coupling.
Described trimming and piercing die die, flanging and restriking die and side blow hole die are successively set on the upper mold core from left to right; Described trimming and piercing die punch, flanging and restriking punch and side blow hole punch are corresponding with trimming and piercing die die, flanging and restriking die and side blow hole die respectively, are successively set on the lower mold core from left to right.
Described upper ejector pin is provided with 8~12.
Compared with prior art, the utlity model has following advantage:
1, production cost is low, omits two secondary moulds, and reduces two procedures, saves the man power and material.
2, eccentric swage uses the structure of upper ejector pin, and convenient for maintaining does not need to check or change the binder power source before each the production.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of automobile A column lower reinforcing plate component die comprises upper die component and following membrane module.
Upper die component comprise upper bolster 9 and be arranged on that upper mold core, patrix on the upper bolster 9 inserted, patrix eccentric swage and 8 upper ejector pins 6; Upper mold core is positioned at the below of upper bolster 9; Be provided with trimming and piercing die die 3, flanging and restriking die 5 and side blow hole die 8 on the upper mold core from left to right successively, upper ejector pin 6 passes the top that upper bolster 9 is connected to upper mold core.
Following membrane module comprises die shoe 1 and is arranged on lower mold core and the ejector on the die shoe 1; Lower mold core is positioned at the top of die shoe 1, is provided with trimming and piercing die punch 2, flanging and restriking punch 4 and side blow hole punch 7 with three kinds of die couplings on the lower mold core from left to right successively.
This working process of mould is following: when press is depressed with specified pressure; The patrix eccentric swage compresses tablet; Do trimming and piercing die, flanging and restriking, the action of side blow hole respectively by the working portion of three stations then, a punching press action is covered, and press rises; Ejector takes out part with part jack-up.
This mould is incorporated into three width of cloth moulds in one width of cloth mould; Integration through mould; Reduced production process; Practiced thrift the man power and material, and adopt upper ejector pin structural change last eccentric swage use the expensive traditional mode of spring or nitrogen spring, saved the expense of maintenance of spring or nitrogen spring and periodic replacement.
