Description
Technical field
Technical field of forging of the present invention, more particularly to vapor-permeable type forging mold.
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）Upper and lower mould close membrane process in, by mechanical external force
Effect, easily produce dislocation phenomenon, influence forging accuracy；（2）In punching press, the air in die cavity can form gas
Capsule, air bag is rebounded by high pressure, causes material to be full of product die cavity.
The content of the invention
The present invention in view of the shortcomings of the prior art, there is provided during a kind of forging accurate positioning, blank full of product die cavity, it is saturating
Gas type forging mold.
The present invention realizes solving above-mentioned technical problem by following technological means：A kind of vapor-permeable type forging mold, including
The upper die and lower die of mutual cooperation；The bottom of the upper mould, the top of lower mould offer die cavity；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 type
Chamber, it has wrapped around the flash gutters；The air-permeable pin-holes of insertion from top to bottom are offered on the resistance bridge of the lower mould；Institute
Stating mould also includes location structure, and the location structure is to the relative position between the spacing upper mould and the lower mould.
Preferably, the location structure includes being arranged on the projection at the top of the lower mould and is arranged on the upper mould bottom
With the groove of the male cooperation；Or, the location structure includes being arranged on the groove at the top of the lower mould and being arranged on
The projection of the upper mould bottom and the groove fit.
Preferably, the projection is distributed in four corners of the upper mould or lower mould；The groove is distributed on described
Four corners of mould or lower mould.
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）By setting location structure of the invention, on the one hand it is easy to check and correction during upper die and lower die conjunction film；On the other hand, prevent
Misplaced in casting process.
（2）In addition, the air-permeable pin-holes of insertion from top to bottom are offered on the lower resistance bridge of lower mould, when closing film, by die cavity
In the air bag that agglomerates into of air discharge in time, prevent air bag from occupying the space of product die cavity, position, cause Flow of Goods and Materials to be received
Resistance, it is impossible to be sufficient filling with product die cavity.
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, further prevent from being sent out in casting process
Raw dislocation.
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.
