Description

A mould for transition awl macrostoma plastic

Technical Field

The utility model relates to an automobile punching part mould technical field provides a mould for transition awl macrostoma plastic very much.

Background

The transition cone is used for connecting the air inlet of the motor vehicle with the catalyst carrier cylinder and has the function of reducing diameter.

The transition cone belongs to an automobile stamping part with a flanging, and an existing die for processing the stamping part cannot enable the stamping part to achieve negative angle processing in the processing process, so that the problem of flanging of the flanging cannot be solved.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a mould for big mouthful of plastic of transition awl.

The utility model discloses a realize like this, a mould for transition awl macrostoma plastic, including upper die base and die holder, the lower part of upper die base is fixed connection upper padding plate, the outer profiled sheeting of periphery fixed connection annular below the upper padding plate, fixed connection inner profiled sheeting on the upper padding plate of outer profiled sheeting inboard, the outer surface of inner profiled sheeting and outer profiled sheeting internal surface are the state of inclining outward that is parallel, open at the center of upper die base, upper padding plate, inner profiled sheeting, the knockout pin passes the round hole at upper die base, upper padding plate, inner profiled sheeting center and is connected with the kicking plate, the lower part of inner profiled sheeting is the recess;

the upper part of the lower die holder is fixedly connected with a lower positioning plate, the upper surface of the lower positioning plate is provided with a groove, and the ejector plate moves up and down in the space between the inner forming plate and the lower positioning plate under the driving of the knockout rod and is used for discharging after the processing is finished.

Furthermore, the upper die base and the lower die base are connected through a guide post, the guide post comprises a guide post and a guide sleeve sleeved at the upper end of the guide post, the guide sleeve is fixed on the upper die base, and the guide post is fixed on the lower die base.

Further, the outer surface of the inner contoured plate is inclined outwardly at an angle of 8 ° to the inner surface of the outer contoured plate.

Compared with the prior art, the utility model has the advantages of: the problem of easily cause the outline of part to stick up outward in the mould course of working of turn-ups part is solved, with the effectual plastic enstrophe of the part portion that sticks up outward to overall part outline size is maintained.

Drawings

The present invention will be described in further detail with reference to the accompanying drawings and embodiments:

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is a diagram of the positional relationship between the outer surface of the inner contoured plate and the inner surface of the outer contoured plate.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, the utility model provides a mould for big mouthful of plastic of transition awl, including upper die base 1 and die holder 2, the below fixed connection upper padding plate 3 of upper die base 1, outer shaping plate 4 of periphery fixed connection annular below upper padding plate 3, fixed connection inner shaping plate 5 on the upper padding plate 3 of outer shaping plate 4 inboard, the outer surface of inner shaping plate 5 and the outer shaping plate 4 internal surface are parallel state that leans out, open at the center of upper die base 1, upper padding plate 3, inner shaping plate 5 has the round hole, material beating rod 7 passes the round hole at upper die base 1, upper padding plate 3, inner shaping plate 5 center and is connected with ejector plate 6, the lower part of inner shaping plate 5 is the recess;

the upper part of the lower die holder 2 is fixedly connected with a lower positioning plate 8, the upper surface of the lower positioning plate 8 is a groove, and the ejector plate 6 moves up and down in the space between the inner forming plate 5 and the lower positioning plate 8 under the driving of the knockout rod 7 and is used for discharging after the processing is finished.
