Compared with the prior art, the special die for the coupler yoke has the characteristics of simple structure, reliable action, labor saving, easy realization of automation and the like; the demolding method has the characteristics of low labor intensity, quick demolding, simplicity and effectiveness, and is easy to realize automation, the production efficiency is improved, and the production cost is reduced.
Description
Technical field
The present invention relates to a kind of particular manufacturing craft and release method, especially the particular manufacturing craft of hook tail frame and release method.
Background technology
Existing hook tail frame adopts compression molding more, its die for special purpose has the patrix upper and lower mould and constitutes, when upper die and lower die fasten, form the cavity of hook tail frame between patrix and the counterdie, after compression molding, hook tail frame needs the demoulding, yet, existing particular manufacturing craft is after moulding, and the demoulding can only be manually to get from the one or both ends sled, and there is following problem in this stripping means:
1), sled gets Shi Weidian contact, and on the overlap that when the moulding of hook tail frame, forms of application point because local pressure and overlap intensity are lower, the overlap easy deformation, thus be to be difficult for the location in the shearing of subsequent technique, cause waste product to produce or increase.
2), artificial sled gets that efficient is lower, difficult sled is got, thereby the time of hook tail frame in die cavity is longer, easily causes the modification of mould inner surface, shortens the life-span of mould.
3), big, the inefficiency of labour intensity got of workman sled, can not automation.
Summary of the invention
Technical problem to be solved by this invention is at above-mentioned the deficiencies in the prior art, and a kind of particular manufacturing craft and release method of hook tail frame of fast demoulding automatically are provided.
For solving the problems of the technologies described above, particular manufacturing craft of the present invention adopts following technical scheme: a kind of particular manufacturing craft of hook tail frame, comprise patrix and counterdie, between described patrix and counterdie, form a hollow cavity that is used for the forging and pressing of hook tail frame, also comprise a demolding structure, this demolding structure comprises at least one through hole that is arranged on the counterdie.
In the upper end of described through hole one movable block is set, the last plane of this movable block and cavity bottom surface are on same plane.
Described demolding structure comprises two through holes that are arranged on the counterdie two ends, and the upper end of these two through holes is connected with cavity.
The described demoulding comprises each through hole at least that is arranged on the shell wall of counterdie both sides.
The described through hole that is arranged on the shell wall of counterdie both sides respectively is 2.
The technical scheme that release method of the present invention adopts is: in the through hole of described lower mould push rod is set, thereby is applying the hook tail frame jack-up realization demoulding of an active force that makes progress with moulding simultaneously on push rod.
Also be provided with a movable block in described through hole upper end, the last plane of this movable block and cavity bottom surface are on same plane, and described push rod acts directly on the movable block and by movable block hook tail frame jack-up is realized the demoulding.
Compared with prior art, the particular manufacturing craft of hook tail frame of the present invention has following advantage:
1, the present invention is provided with demolding structure on the particular manufacturing craft of hook tail frame, comprise at least one through hole that is arranged on the counterdie at demolding structure, adopt the mould of this structure, behind hook tail frame forging forming, only need in the counterdie through hole, to be provided with a push rod, act on hook tail frame in the cavity body of mould by promoting push rod, thereby, realize the demoulding hook tail frame jack-up fast.
2, mould of the present invention also can be provided with a movable block in the through hole upper end, when the demoulding, thereby the active force of jack-up hook tail frame is acted on the movable block, it is bigger that the area of movable block can be done, thereby increase the acting surface of power, reduce the deformation effect that local pressure causes hook tail frame when jack-up.
3, the through hole of demolding structure can be arranged on the through hole on the shell wall of counterdie both sides, when the forging forming of hook tail frame, on the shell wall of counterdie both sides, can produce overlap, the position of this through hole is just in time in flash locations, so when realizing jack-up, power just in time acts on the overlap, can not exert an influence to hook tail frame.
4, by the demolding structure of through hole is set at counterdie, simple in structure, reliable effect is saved the labour simultaneously, and easily is automated.
Adopt mould of the present invention to realize that the advantage of the demoulding is:
1, the present invention is by being provided with the demolding structure of a jack-up on lower mould, the active force of this demolding structure acts directly on the interior hook tail frame of cavity, thereby it is hook tail frame is quick, jack-up is realized the demoulding reliably, compared with prior art, have that labour intensity is low, the demoulding is fast and the simple and effective characteristics of method.
2, the demoulding is adopted and in the counterdie through hole push rod is set, and when the demoulding, thereby promotes push rod with the demoulding of hook tail frame jack-up, and release method is simple, easily is automated, and enhances productivity, reduces production costs.

The specific embodiment
Below in conjunction with accompanying drawing, the present invention is elaborated:
Embodiment 1
As shown in Figure 1, particular manufacturing craft of the present invention comprises patrix 1 and counterdie 2, forms the cavity 3 of hook tail frame between patrix 1 and counterdie 2, be provided with at least one through hole 21 in the bottom of counterdie 2, in the present embodiment, this through hole is 1, and the upper end of this through hole 21 is connected with cavity 3.Behind the forging forming of hook tail frame, only need in this through hole 21, a push rod to be set, act on this push rod then and move upward, the hook tail frame jack-up that can will be connected with through hole 21 upper ends is realized fast demoulding.
As shown in Figure 2, counterdie 2 is provided with at least one through hole 21, in this embodiment, through hole is 1, on through hole 21 positions of this counterdie 1, also be provided with groove, in this groove, be provided with a movable block 4, through hole 21 links to each other with movable block 4, the shape of movable block 4 can be circle, rectangle or arbitrary shape, the size of top surface area determines according to the through hole number, when through hole more for a long time, the area of movable block 4 can be less relatively, also can a fixedly connected rod member in the lower end of movable block 4, this rod member passes through hole 21.After this mould forging and pressing hook tail frame moulding, the push rod in the through hole 21 at first acts on the movable block 4, remakes by movable block 4 then to be used on the hook tail frame, and little acting surface is become big acting surface, in the demoulding, reduces the deformation effect to hook tail frame.
As shown in Figure 3, at last at least one through hole that is provided with of counterdie 2 both sides shell walls, the flash locations that the position of this through hole produces when just in time being positioned at hook tail frame forging forming, in the present embodiment, the through hole on each side shell wall respectively is 2 and is respectively hole 41,42.After this mould forging and pressing hook tail frame moulding, the push rod in the hole acts directly on the overlap, in the demoulding, can not produce the distortion of hook tail frame.
Embodiment 4
As shown in Figure 4, a through hole first through hole 31, second through hole 32 are set respectively also at the two ends of counterdie separately, or through hole is set on counterdie two ends and shell wall simultaneously simultaneously, the application point of power is more more to be disperseed, and acts on more reliably, is out of shape little.
