Description
Technical field
The utility model belongs to mold design technical field, more particularly to reverse shift cantilever guiding type molding die.
Background technology
In the prior art, in the mold design of forging molding process, the angle position of cavity is always the difficult point of the process.
The curved surface degree of reverse gear class product is larger, and the method for forging, which would generally be used, extrudes the embryo material heated by mould, promotees
Embryo material deformation is set to be filled in walking to expect in the cavity for belong to plug to realize the shaping of curvature.However, often because falling
The location hole of shelves and the curved surface of pilot hole are larger, force shaping mould to cavity deep trouth that the cavity design of reverse gear is convergence right angle.
Such design can make blank during material is walked, suddenly encounter convergence vertical angle cavity deep trouth and deflecting filling it is too late
When so that shaped article easily produces the mass defect of folding and defect at the position.And with regard to the small-scale defect of only one,
Product post-production qualification rate is likely to play conclusive effect, has very big influence to the quality cost of enterprise.
The method that general forging molding uses is point modular angle degree by changing molding die, to reach the angle angle for reducing the product
Degree, reduces folding and the defects of defect occurs so that coefficient remains high the defects of product.
Utility model content
The technical problem that the utility model solves is that existing reverse gear design can be such that blank is suddenly encountered during material is walked
The cavity deep trouth of convergence vertical angle and deflecting filling are not in time so that shaped article easily produces folding and defect at the position
Mass defect.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution:Reverse shift cantilever guiding type into
Pattern has, including upper die and lower die, and molding groove profile is useful in upper die and lower die, and groove profile includes location hole groove profile, is oriented to
Hole-and-slot and cantilever groove profile, location hole groove profile, guiding hole-and-slot are sequentially connected with cantilever groove profile, and the groove profile inner bottom surface is set
There is a guide channel of " S " type, guide channel along location hole groove profile and is oriented to hole-and-slot and sets successively, and guide channel end is to cantilever groove profile
Through extension.
Using above-mentioned technical proposal, in the utility model, the groove profile inner bottom surface is equipped with the guide channel of " S " type, guide channel
Set successively along location hole groove profile and guiding hole-and-slot, guide channel end is to cantilever groove profile through extension.It can so imitate and subtract
Slow blank is being walked to expect the angle change of process, is relieving the embryo material brought by unexpected wide-angle variations and fill not in time, effectively
Reduce the incidence of fork defect.Guide channel along location hole groove profile and is oriented to hole-and-slot setting successively, so can be more preferable
The material of walking of corner is enriched.The use of this mould, can make the product form after shaping fuller；Tracing pattern guide channel,
It effectively prevent the occurrence probability that special-shaped position lacks material；This die parting line effectively slow down embryo material by the effect of curved surface radian
In forming process to the abrasion of mould.
Further, the guiding slot cross-section is isosceles trapezoidal structure, can so accelerate to walk the speed of material, quickly be filled out
Fill.
Further, the width of the guide channel is 3cm~5cm, for some large-scale reverse gear structures, ensures that it is walked material and fills
Real its walks material rapidly, ensures yield rate.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is structure front view in embodiment in reverse shift cantilever guiding type molding die.
Embodiment
Embodiment 1
As shown in Figure 1：Reverse shift cantilever guiding type molding die, including upper die and lower die, have in upper die and lower die
For molding groove profile 1, groove profile 1 includes location hole groove profile 11, is oriented to hole-and-slot 12 and cantilever groove profile 13, location hole groove profile
11st, it is oriented to hole-and-slot 12 sequentially to connect with cantilever groove profile 13,1 inner bottom surface of groove profile is equipped with the guide channel 2 of " S " type, guiding
Groove 2 is set along location hole groove profile 11 and guiding hole-and-slot 12 successively, and 2 end of guide channel is to cantilever groove profile 13 through extension.Institute
It is isosceles trapezoidal structure to state 2 section of guide channel.The width of the guide channel 2 is 3cm~5cm.
During work, 1 inner bottom surface of groove profile is equipped with the guide channel 2 of " S " type, and guide channel 2 is successively along 11 He of location hole groove profile
It is oriented to hole-and-slot 12 to set, 2 end of guide channel is to cantilever groove profile 13 through extension.It can so imitate and slow down blank and walking to expect
The angle change of journey, relieves the embryo material brought by unexpected wide-angle variations and fills not in time, effectively reduce fork defect
Incidence.Guide channel 2 is set along location hole groove profile 11 and guiding hole-and-slot 12 successively, so can be preferably by corner
Material is walked to enrich.The use of this mould, can make the product form after shaping fuller；The guide channel 2 of tracing pattern, effectively avoids
Special-shaped position lacks the occurrence probability of material；This die parting line effectively slow down embryo material and be molded by the effect of curved surface radian
To the abrasion of mould during journey.2 section of guide channel is isosceles trapezoidal structure, can so accelerate to walk the speed of material, is carried out fast
Speed filling.The width of the guide channel 2 is 3cm~5cm, for some large-scale reverse gear structures, ensures that it is walked substantial its of material and walks
Material is rapid, ensures yield rate.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, on the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these should also be considered as this
The protection domain of utility model, these are all without the effect and practical applicability for influencing the utility model implementation.
