Description

Forging mold based on fillet structure
Technical field
Technical field of forging of the present invention, more particularly to the forging mold based on fillet structure.
Background technology
Auto parts and components such as hub bracket, three arm flanges etc. generally carry out conducting forging processing by the way of high temperature hydraulic pressure.It is logical Cross and the blank after intermediate frequency heating is processed is placed in the product die cavity of lower mould, in the case where mold is driven by hydraulic cylinder Pressure, is forged, then mold is lifted, and product formation manually takes out product in the die cavity of lower mould, completes the forging of product Make.
The forging mold of prior art has the following disadvantages:(1)The edge of traditional its die cavity of mould is linearly, and it is turned Angle is pointed at structure, and material is in forging, it is easy to flow back, and produces lamination;(2)The depth of the traditional moulds die cavity of mould thereon is small In the depth of the die cavity of lower mould, after forging, product formation is not easily taken out in the die cavity of lower mould.
The content of the invention
The present invention is in view of the shortcomings of the prior art, there is provided product stack crack occurs, is easy to forging after one kind prevents forging The forging mold based on fillet structure that product takes out afterwards.
The present invention realizes solving above-mentioned technical problem by following technological means:A kind of forge mould based on fillet structure Tool, including the upper die and lower die for cooperating;The bottom of the upper mould, the top of lower mould offer die cavity;The mould of the upper mould Chamber depth is deeper than the cavity depth of the lower mould;The die cavity of the upper die and lower die include resistance bridge, product die cavity, flash gutters, Jaw;Resistance bridge structure in a ring, its inner side forms described product die cavity, and it has wrapped around the flash gutters;It is described One section or several sections of interruption in resistance bridge rides out laterally, forms fillet structure.
Preferably, jaw is offered in the flash gutters, the jaw is communicated to the edge of correspondence mould.
Preferably, the fillet structure is in gentle slope shape, and its height is gradually reduced from inside to outside.
Preferably, the Blind locating holes being oriented to from top to bottom are offered at the top of the lower mould, is inserted in the Blind locating holes There is ejector beam;The bottom of mould is provided with the locating slot coordinated with the ejector beam on described.
Preferably, the locating slot, ejector beam are respectively positioned on the center of corresponding product die cavity.
The advantage of the invention is that:
(1)Several sections due to a section in resistance bridge of the invention or interruption ride out laterally, form fillet structure, work as forging When, due in the presence of the round-corner transition structure, effectively preventing Flow of Goods and Materials to be obstructed, flowing back produces the phenomenon of stack crack.
(2)The depth of the die cavity of lower mould, after the completion of forging, product formation are deeper than due to the cavity depth of upper mould of the invention In the die cavity of upper mould.After product die cavity is lifted, product is subject to downward Action of Gravity Field, has and is taken off automatically from the die cavity of upper mould From trend, lower mould compared to existing technology departs from, it is easier to take out product.
Further, the fillet structure of gentle slope shape is set, is easy to the clout in product die cavity to flow out, further prevent lamination from splitting The generation of line.Further, since offering jaw in flash gutters, when die cavity of the formed product in upper mould, inserted by prizing part The jaw of supreme mould, you can prize shaped article.
Further, when forging when, be inserted into the locating slot of mould at the top of the ejector beam of lower mould, be further easy on Mould, lower mould close the check and correction and fit and raised mutual cooperation locking effect during film, and generation is wrong in preventing casting process Position.
Further, locating slot, ejector beam are respectively positioned on the center of corresponding product die cavity.When forging such as three arm flange, due to Mould is provided centrally with solid frustum cone structure, can no doubt be inserted into ejector beam and is arranged in frustum cone structure.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the forging mold based on fillet structure of the present invention.
Fig. 2 is the structural representation of lower mould in a kind of forging mold based on fillet structure of the present invention.
Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is A part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art The every other embodiment obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
Embodiment 1
As shown in Figure 1-2, the present embodiment discloses a kind of forging mold based on fillet structure, including cooperate upper mould 1, under Mould 2.The bottom of upper mould 1, the top of lower mould 2 offer die cavity.Upper mould 1 of the invention, lower mould 2 mold cavity shapes it is corresponding.
The die cavity of upper mould 1 includes upper resistance bridge 11, upper product die cavity 12, upper flash gutters 13.Upper resistance bridge 11 is tied in a ring Structure, its inner side forms upper product die cavity 12, and it has wrapped around flash gutters 13.One section in upper resistance bridge 11 or interruption Several sections ride out laterally, fillet structure 111 in formation.
The die cavity of lower mould 2 includes lower resistance bridge 21, lower product die cavity 22, lower flash gutters 23.Lower resistance bridge 21 is tied in a ring Structure, its inner side forms lower product die cavity 22, and it has wrapped around lower flash gutters 23.One section in lower resistance bridge 21 or interruption Several sections ride out laterally, form lower fillet structure 211.
The mould also includes location structure.Location structure includes being arranged on the projection at the top of lower mould and is arranged on mould bottom Portion and the groove of male cooperation.Or, location structure includes being arranged on the groove 5 at the top of lower mould 2 and is arranged on the bottom of mould 1 Raised 3 coordinated with groove 5.The cavity depth of upper mould 1 is deeper than the cavity depth of lower mould 2.
Several sections due to the present invention one section in resistance bridge or interruption ride out laterally, form fillet structure, work as forging When making, due to there is the round-corner transition structure, Flow of Goods and Materials is effectively prevented to be obstructed, backflow produces stack crack.
By setting location structure of the invention, on the one hand it is easy to check and correction during the 2-in-1 film of upper mould 1, lower mould;On the other hand, Groove 5 cooperates with raised 3 and locks, and prevents from being misplaced in casting process.
The depth of the die cavity of lower mould 2, after the completion of forging, product formation are deeper than due to the cavity depth of upper mould 1 of the invention In the die cavity of upper mould 1.After product die cavity is lifted, product is subject to downward Action of Gravity Field, there is automatic from the die cavity of upper mould 1 The trend of disengaging, lower mould 2 compared to existing technology departs from, it is easier to take out product.
In addition, the air-permeable pin-holes 26 of insertion from top to bottom are offered on the lower resistance bridge 21 of lower mould 2, when closing film, by mould The air bag that air in chamber is agglomerated into is discharged in time, prevents air bag from occupying the space of product die cavity, position, causes Flow of Goods and Materials It is obstructed, it is impossible to be sufficient filling with product die cavity.
