Description
Technical field
The utility model relates to the field of forging, in particular to a kind of cavity plate equipped with stress release mouth slot.
Background technique
For convenience of the material returned of the forging of some special constructions, the cavity plate with combination mold core starts to be frequently used.Such
Outer die cavity is formed in the ontology of the cavity plate of type, combination mold core includes several modules, and it is intracavitary that several modules are placed in external mold,
One end of several modules is encircled into an inside cavity, which is the extrusion molding die cavity of target forging.The prior art
In the cavity plate with combination mold core have the drawback that in forging extrusion process, each comprising modules pair of combination mold core
The end of outer die cavity forms huge extruding force and is easy to cause the edge generation of outer die cavity end to burst apart, to cause cavity plate
Ontology is scrapped.
Utility model content
In order to solve the above technical problems, the utility model proposes a kind of inner hole reversely push up the fixture that rises, technical solution is such as
Under:
A kind of cavity plate equipped with stress release mouth comprising:
Ontology, be formed on the ontology include several conduits star-shaped outer die cavity, the end of each conduit is equal
Equipped with the stress release notch being connected to conduit described in this；
Combination mold core, matched module forms the combination mold core one by one with several conduits by several, each mould
Block correspondence is placed in the corresponding conduit, and one end of each module is encircled into the inside cavity of a closure, each institute
The other end for stating module is then resisted against the end of the conduit.
Further, the conduit is rectangular shape, and two edges of the end of each conduit are equipped with an institute
State stress release notch
Further, be formed with concaveconvex structure on the inner wall of the inside cavity, the shape and size of the concaveconvex structure with
The shape and size of the lateral profile of forging to be formed match.
Further, the stress release mouth includes the circular head that long and narrow body part is formed in body part end,
The diameter on the head is greater than the width of the body part.
The cavity plate equipped with stress release mouth of the utility model can discharge outer die cavity in extrusion process in time
The stress of edge extends the service life of cavity plate so that externally die cavity forms effective protection.
Detailed description of the invention
In order to illustrate more clearly of the technical solution of the utility model embodiment, will be needed below to described in embodiment description
Attached drawing to be used is briefly described, it should be apparent that, the accompanying drawings in the following description is only some implementations of the utility model
Example, for those of ordinary skill in the art, without creative efforts, can also obtain according to these attached drawings
Obtain other attached drawings.Wherein:
Fig. 1 is the structural schematic diagram of the ontology of cavity plate provided by the utility model；
Fig. 2 is the structural schematic diagram of the mold core of cavity plate provided by the utility model；
Fig. 3 is the partial enlarged view of the stress release mouth in Fig. 1.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1 and Figure 2, in a specific embodiment, provided by the utility model recessed equipped with stress release mouth
Mould comprising ontology and combination mold core 20.Wherein:
It is formed on the ontology including there are six the star-shaped outer die cavity 10 of conduit 101, in the present embodiment, described in six
Conduit 101 is rectangular shape, and two edges of the end of each conduit 101 are equipped with a stress release mouth 102.It is right
It answers, by six, matched module 201 forms the combination mold core 20 one by one with six conduits 101, wherein each mould
The correspondence of block 201 is placed in the conduit 101.One end of each module 201 be encircled into one closure substantially at
The inside cavity 30 of hexagon, the inside cavity 30 are the extrusion molding die cavity of forging to be formed.Each module
201 other end is then resisted against the end of the conduit 101.
Further, with continued reference to shown in Fig. 2, in the present embodiment, concave-convex knot is formed on the inner wall of the inside cavity 30
Structure, the shape and size of the concaveconvex structure match with the shape and size of the lateral profile of forging to be formed.Certainly, exist
It, can be according to the specific structure of forging to be formed, to the tool of the outer die cavity, the combination mold core in some other embodiment
Shape and structure are adaptively adjusted.It only needs to guarantee, the end of the conduit of the outer die cavity is provided with stress release notch
?.
The working principle of the cavity plate equipped with stress release mouth in the present embodiment is as follows:
Six modules 201 are placed in correspondingly in six conduits 101, to construct the inside cavity
30, then forging stock is placed in the inside cavity 30.Control punch-pin (not shown) is pressed down against forging stock, in extrusion process, forging
Material in base flows and is gradually filled with the inside cavity 30, to realize the extrusion forming of forging.
In extrusion process, for forging stock material outwardly against each module 201, each module 201 is synchronous outwardly against institute
The outer end for stating each conduit 101 of outer die cavity 10, since the edge of the outer end of each conduit 101 is equipped with stress release mouth
102.102 elasticity of stress release mouth is opened, so that release aggregation in time prevents each to the stress at the outer end of each conduit 101
The outer end of conduit 101, which generates, bursts apart.
Preferably, in order to promote the elasticity of the stress release mouth 102, or perhaps stress release ability.Such as Fig. 3 institute
Show, the stress release mouth 102 includes long and narrow body part 102a and the circular head for being formed in the end body part 102a
The diameter of 102b, the head 102b are greater than the width of the body part 102a.Circular head 102b's can be equal by stress
Even release is not easy to be torn.
As it can be seen that the cavity plate equipped with stress release mouth in the present embodiment can discharge external mold in extrusion process in time
The stress of the edge of chamber extends the service life of cavity plate so that externally die cavity forms effective protection.
The description with certain particularity detailed enough has been carried out to the utility model above.It is common in fields
It is to be understood by the skilled artisans that the description in embodiment is only exemplary, without departing from the utility model true spirit and
All changes are made under the premise of range all should belong to the protection scope of the utility model.The utility model is claimed
Range is to be defined by described claims, rather than limited by the foregoing description in embodiment.
