Abstract

The utility model discloses a self-guide forming die, comprising a lower die base, a die base plate, a die, a punch fixing plate, an upper die base plate, an upper die base, a punch and a die shank, wherein guide pillars are additionally arranged at the two sides of the punch, the punch body of the punch stretches out of the bottom end of each guide pillar, and the lengths of the two guide pillars are consistent. According to the utility model, the two guide pillars are additionally arranged at the two sides of a common punch, and each guide pillar is longer than the punch body; during operation, the projecting part of each guide pillar of the punch is firstly contacted with the lower die and exerts guiding effect, then the punch body in the middle is contacted with part blank and exerts part moulding effect, and the guide pillars and the punch body are integrated, thus the punch body is reinforced and protected, and service life of the die is prolonged.

Description

A kind of from the correcting shaping mould

Technical field

The utility model relates to a kind of from the correcting shaping mould.

Background technology

It is to process through mould molding that the machinery industry has a lot of stamping parts.Fig. 1 is a kind of U-shaped part 11, and general U-shaped mould is to realize mould correcting up and down through mould bases or inner guiding post, therefore; Need the template of mould bigger; Die cost is higher, and because the material of U-shaped part 11 is thicker, and forming open is less; And the intensity of drift is lower, and mould is fragile and cause the life-span not long.

The utility model content

For solving the problems of the technologies described above, it is a kind of from the correcting shaping mould that the utility model provides, and to improve the mechanical strength of drift, prolongs the service life of mould.

For achieving the above object, the technical scheme of the utility model is following:

A kind of from the correcting shaping mould; Comprise die shoe, die backing plate, die, drift fixed head, upper die plate, upper bolster, drift and die shank; Said drift is installed on the said drift fixed head; Said die is fixed on the said die backing plate through backstay, and is provided with inner shoe in the said die; Said die shoe bottom also is provided with the bullet ejection device, and said bullet ejection device is connected with push rod, and said push rod passes said die shoe and stretches in the cavity of said die; The both sides of said drift add guide pillar, and the drift body of said drift is stretched out in the bottom of said guide pillar, and two said guide pillar length are consistent.

Preferably, said guide pillar is cylindric, and with said drift body integrated molding.

Through technique scheme, the utility model provide from the correcting shaping mould, it installs two guide pillars additional through the both sides at common drift; And guide pillar grows a part than drift body, therefore, under the patrix towards the time; The guide pillar ledge of drift at first contacts the correcting effect of playing with counterdie, middle then drift body contacts the forming parts effect of playing with part blank, and drift body and guide pillar partly are made of one simultaneously; The drift main body to strengthening and protective effect, has been increased die life.

The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.

According to Fig. 2 to 4; The utility model provide from the correcting shaping mould; Comprise die shoe 21, die backing plate 22, die 23, drift fixed head 24, upper die plate 25, upper bolster 26, drift 28 and die shank 27; Drift 28 is installed on the drift fixed head 24, and die 23 is fixed on the die backing plate 22 through backstay 210, and is provided with inner shoe 29 in the die 23; Die shoe 21 bottoms also are provided with and play ejection device 212, play ejection device 212 and are connected with push rod 211, and push rod 211 passes die shoe 21 and stretches in the cavity of die 23; The both sides of drift 28 add guide pillar 42, and the drift body 41 of drift 28 is stretched out in the bottom of guide pillar 42, and two guide pillar 42 length are consistent.Wherein, guide pillar 42 is cylindric, and with drift body 41 integrated moldings.

The utility model provide from the correcting shaping mould, it installs two guide pillars 42 additional through the both sides at common drift, and guide pillar 42 grows a part than drift body 41; Therefore, under the patrix towards the time, guide pillar 42 ledges of drift 28 at first contact the correcting effect of playing with counterdie; Drift body 41 then contacts the forming parts effect of playing with part blank; Drift body 41 is made of one with guide pillar 42 parts simultaneously, drift body 41 is played strengthen and protective effect, has increased die life.

Defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.

Claims

1. one kind from the correcting shaping mould; Comprise die shoe, die backing plate, die, drift fixed head, upper die plate, upper bolster, drift and die shank; Said drift is installed on the said drift fixed head; Said die is fixed on the said die backing plate through backstay, and is provided with inner shoe in the said die; Said die shoe bottom also is provided with the bullet ejection device; Said bullet ejection device is connected with push rod; Said push rod passes said die shoe and stretches in the cavity of said die, it is characterized in that, the both sides of said drift add guide pillar; The drift body of said drift is stretched out in the bottom of said guide pillar, and two said guide pillar length are consistent.
