Abstract
The utility model provides a kind of rear mandrel mould for forging, it is characterised in that including cope plate and lower template；The cope plate includes upper cavity and the projection being arranged in the upper cavity；The lower template includes lower mode cavity and the cavity being arranged in the lower mode cavity；The upper cavity and the lower mode cavity cooperatively form the die cavity of accommodating rear mandrel forging；The contact surface formation die joint of described raised and described cavity.So that curve point mould is only in centre position, remaining surface is plane, therefore alleviates the manufacture fit precision requirement of mould die joint, improves production efficiency while improving the precision of forging.
Description
Technical field
The utility model is related to rear mandrel processing technique field, more particularly to a kind of rear mandrel mould for forging.
Background technology
At present, rear mandrel forging is curve point forging part, and the mould die joint fit precision of curve point mould requires higher,
And lateral pressure easily is produced on point modular surface in forging process, make Die lock catch abrasion aggravation, produce forging wrong
Mould.
Utility model content
The shortcoming of prior art in view of the above, the purpose of this utility model is to provide a kind of rear mandrel forging mould
Tool, requires higher, and hold in forging process for solving the mould die joint fit precision of curve point mould in the prior art
Lateral pressure easily is produced on point modular surface, makes Die lock catch abrasion aggravation, makes the problem of forging produces mismatch.
The utility model provides a kind of rear mandrel mould for forging, including cope plate and lower template；The cope plate includes upper
Die cavity and the projection being arranged in the upper cavity；The lower template includes lower mode cavity and is arranged on recessed in the lower mode cavity
Chamber；The upper cavity and the lower mode cavity cooperatively form the die cavity of accommodating rear mandrel forging；Described raised and described cavity connects
Contacting surface formation die joint.
In an embodiment of the present utility model, the raised top is higher than the end face of the cope plate；Described point of mould
The height in face is less than the top surface of the cavity.
In an embodiment of the present utility model, the die joint is curved surface.
In an embodiment of the present utility model, the contact surface of the cope plate and the lower template is in addition to die joint
Plane.
As described above, a kind of rear mandrel mould for forging of the present utility model, has the advantages that：
So that curve point mould is only in centre position, remaining surface is plane, therefore alleviates the manufacture of mould die joint and match somebody with somebody
Required precision is closed, production efficiency is improved while improving the precision of forging.

Embodiment
Illustrate embodiment of the present utility model below by way of specific instantiation, those skilled in the art can be by this theory
Content disclosed by bright book understands other advantages of the present utility model and effect easily.The utility model can also be by addition
Different embodiments are embodied or practiced, and the various details in this specification can also be based on different viewpoints with answering
With, without departing from it is of the present utility model spirit under carry out various modifications or alterations.It should be noted that, in situation about not conflicting
Under, the feature in following examples and embodiment can be mutually combined.
It should be noted that the diagram provided in following examples only illustrates of the present utility model basic in a schematic way
Conception, then in schema only display with relevant component in the utility model rather than according to component count during actual implement, shape
And size is drawn, it is actual when implementing, and kenel, quantity and the ratio of each component can be a kind of random change, and its assembly layout
Kenel may also be increasingly complex.
Referring to Fig. 1 to Fig. 4, it should however be clear that structure, ratio, size depicted in this specification institute accompanying drawings etc., only to
The content disclosed in specification is closed, so that those skilled in the art is understood with reading, being not limited to the utility model can
The qualifications of implementation, therefore do not have technical essential meaning, the tune of the modification of any structure, the change of proportionate relationship or size
It is whole, in the case where not influenceing the utility model effect that can be generated and the purpose that can reach, all should still it fall in the utility model institute
The technology contents of announcement are obtained in the range of covering.Meanwhile, in this specification it is cited as " on ", " under ", "left", "right",
The term of " centre " and " one " etc., is merely convenient to understanding for narration, and is not used to limit the enforceable scope of the utility model,
Its relativeness is altered or modified, under without essence change technology contents, when being also considered as the enforceable category of the utility model.
As shown in Figures 1 to 4, the structural representation of mandrel forging after Fig. 1 is shown as in the utility model.Fig. 2 is shown as
Fig. 1 right view.Fig. 3 is shown as the structural representation of lower mould in rear mandrel mould for forging in the utility model.Fig. 4 is shown as this
The structural representation of mould is gone up after in utility model in mandrel mould for forging.The utility model provides a kind of rear mandrel mould for forging,
Including cope plate 2 and lower template 1；Cope plate 2 includes upper cavity and the projection being arranged in upper cavity；Lower template 1 includes lower mould
Chamber and the cavity being arranged in lower mode cavity；Upper cavity and lower mode cavity cooperatively form the die cavity of accommodating rear mandrel forging；It is raised and recessed
The contact surface formation die joint 3 of chamber.Pass through the setting of this die joint 3, it is possible to reduce the mismatch power of mould, reduce mould point
Die face 3 manufactures the requirement of fit precision.
In an embodiment of the present utility model, raised top is higher than the end face of cope plate 2；The height of die joint 3 is low
In the top surface of cavity.As in Fig. 3, in the lower template 11 of rear mandrel forge piece mold structure, the top middle cavity of lower template 11 is recessed
Enter the surface of lower template 1.As in Fig. 4, in the cope plate 22 of rear mandrel forge piece mold structure, the top centre of cope plate 22 is local
Protrude the surface of cope plate 2.
Further, die joint 3 is curved surface.Preferably, cope plate 2 and the contact surface of lower template 1 are in addition to die joint 3
Plane.By using this design form so that curve point mould is only in middle empty cavity position, and remaining surface is plane, is subtracted
The lateral pressure that will be produced on small point of modular surface, therefore the manufacture fit precision requirement of mould die joint 3 is alleviated, improve
Production efficiency improves the precision of forging simultaneously.
In summary, rear mandrel mould for forging of the present utility model so that curve point mould is only in centre position, remaining surface
It is plane, therefore alleviates the manufacture fit precision requirement of mould die joint, improves production efficiency while improving forging
Precision.So, the utility model effectively overcomes various shortcoming of the prior art and has high industrial utilization.
Above-described embodiment only illustrative principle of the present utility model and its effect are new not for this practicality is limited
Type.Any person skilled in the art can all be carried out without prejudice under spirit and scope of the present utility model to above-described embodiment
Modifications and changes.Therefore, such as those of ordinary skill in the art without departing from the essence disclosed in the utility model
God and all equivalent modifications completed under technological thought or change, should be covered by claim of the present utility model.
