Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
A kind of flange low-angle closed molds offer on the side wall of lower die 2 as shown in Figure 1, including upper mold 1 and lower die 2
Allocating slot 111 is played, when upper mold 1 breaks down or needs manually to be operated, can be provided by playing an allocating slot 111 by one
By means of force, upper mold 1 can be tilted by other auxiliary tools, be allowed to separate with lower die 2.
As shown in Fig. 2, upper mold 1 includes attachment base 11 and is fixedly connected on the pressing mold 12 of 11 lower end of attachment base, on pressing mold 12
It is provided with draft angle 121, draft angle 121 includes the first circular arc 1211, the second circular arc 1212 and the third circular arc being wholely set
1213, the first circular arc 1211, the second circular arc 1212 and third circular arc 1213 are disposed as tending to the skewed of the center of circle downwards, and first
The inclined angle of circular arc 1211 is less than the inclined angle of third circular arc 1213, three circles of integrated design less than the second circular arc 1212
Arc reduces the frictional force with flange, can smoothly be detached from flange when upper mold 1 rises.
As shown in Fig. 2, the top of draft angle 121 is equipped with the protrusion 122 of several arc-shapeds, the annularly distribution of protrusion 122 is convex
The top for playing 122 opens up fluted 1, and the corner angle of one 123 inner sidewall of groove are set as arc-shaped, and the design of arc-shaped can
Reduce the friction with flange, and the pushing shock flange rear defence of upper mold 1 stops flange and edges and corners are clamped, and demoulds flange smoothly,
The bottom side of the wall of groove 1 is set as open arc-shaped, makes flange be easier to loosen, flange can be made quickly to demould.
As shown in Fig. 2, 11 lower end surface of attachment base is opened up, there are two centrosymmetric grooves 24.
As shown in figure 3, the upper surface of lower die 2 is opened up there are two groove 35 corresponding with the matching of groove 24, upper mold 1 is pushed
Groove 24 and groove 35 will form certain gap when coincidence with lower die 2, mold when upper mold 1 being prevented to be overlapped with lower die 2
It is interior to generate pressure difference with ambient atmosphere, cause upper mold 1(as shown in Figure 2) flange is sticky, the normal operation of mold is influenced,
Gap can keep the pressure inside and outside mold consistent, demould flange smoothly.
As shown in figure 4, it is flange shape that upper mold 1, which combines the cavity 3 formed with lower die 2, in upper mold 1 with draft angle 121
It is set as vertical shape with corresponding part, when upper mold 1 pushes forging, huge impact force is generated to flange, flange and lower die 2 are tight
Patch, the setting of the vertical shape of lower die 2 separate flange with upper mold 1, stripping rate so that lower die 2 generates certain pulling force to flange
And significant effect.
Specific work process: raw material to be forged and pressed are placed in lower die 2, and upper mold 1 pushes, and generate immense pressure, flange
It is forged into 3 shape of cavity of pressing mold 12 and the generation of lower die 2, upper mold 1 is promoted, circular arc setting and draft angle on pressing mold 12
121, which can smoothly make flange fall off with upper mold 1, separates, and the flange that staff completes forging takes out, repetitive operation.
The above embodiments are only the explanation to the utility model, are not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
