Description
Technical field
The present invention relates to technical field of mold, specially a kind of aluminium alloy diel with ejecting function.
Background technology
Punching press is to apply pressure to material using the mold being mounted on forcing press, it is made to generate separation or plastic deformation,
To obtain a kind of pressure processing method of required part.Stamping die is essential parts in punching course.It is existing
Punching press carries out punching press primarily directed to the harder material of the materials such as metal material, but with the increase to aluminum alloy materials demand,
It is essential to need to carry out punching press to aluminium alloy, but aluminium alloy quality is softer, it is easy to it deforms, it is de- in order to be easy
Mould can all be provided with liftout attachment on stamping die, part is ejected by liftout attachment, good in order to eject effect, ejection dress
It sets and multiple thimbles is generally set, ejected part by moving up and down for thimble.Due to aluminium alloy quality is softer, rushing
Part is pressed in lower die due to elevated pressures during pressure, aluminum alloy materials can be even pressed onto sometimes in ejection through-hole, institute
It is right in order to reduce the damage of part, to need to reduce thimble quantity in the stamping die of aluminium alloy, but after reducing thimble quantity
Reduction is had in the jack-up effect of part.
As provided a kind of aluminium alloy diel liftout attachment in China Patent No. CN201720393413.X, pass through
Two horizontally movable plates are set at left and right sides of lower die, are inserted between part and mold core using the plug on plate, from
And part is jacked up in the case where reducing thimble and not injuring part；But the device is still provided with thimble and top in lower die
Go out through-hole, aluminium alloy, which still has to be pressed onto during punching press, to be ejected in through-hole；Still further aspect because thimble end compared with
Carefully, when ejecting part, can because stress and the too small reason of forced area can cause piece surface dent, to influence zero
Part quality, so needing one kind being used for aluminium alloy diel in industry, to solve problems faced in industry.
