Description
Technical field
The present invention relates to the technical fields of mold, are especially a kind of liftout attachment for bumper mold.
Background technique
With the development of the automobile industry, bumper is as a kind of important safety device in addition to having the function of protection
In addition, lightweight is also pursued, and in order to reach light-weighted purpose, it is logical that the front/rear collision bumper of automobile has been all made of plastic material
Mold is crossed to be injection moulded.And bumper made of plastics has good intensity, rigidity and dicoration, and can be
It can be until buffer function, protection front and back car body when automobile collides.In the prior art bumper can by headlight or after
Panel holds together at the lampshade position of lamp, to increase aesthetics, but so, increases bumper
Complexity, inner surface have the structures such as cambered surface, back-off, this brings the liftout attachment of injection molding very big complexity.
In the prior art, big straight jacking block and big is typically provided in the two ends of shaped article for the mold of automobile bumper molding
Oblique top block structure, big straight jacking block, which passes through the straight mandril being vertically arranged, to be pushed and moves straight up, and big slanted kicking block is set by oblique
The angle ejector rod set pushes up, also, slanted kicking block has the inclined-plane that can cooperate with type core, integrally moves upwards in slanted kicking block
During, the top of slanted kicking block to the right or is moved to the left simultaneously.
Generally, it can be realized the demoulding requirement of bumper product substantially using existing mould structure, but practical
In production, when the topology requirement that panel is linked together at the especially above-mentioned lampshade position for increasing headlight or back light, use
Traditional mold cannot achieve the disposable complete demoulding of bumper product, this is because the panel at lampshade position has
There is inner concave, small straight roof construction certainly will be set in the mold at lampshade panel, so, at bumper lampshade position
Just there is big straight roof construction, small straight roof construction and ramp-roof structure, therefore, the mould inside at the position is extremely complex, meanwhile, by
In the presence of ramp-roof structure, it carry out the demoulding of big straight roof construction, small straight roof construction and ramp-roof structure step by step, otherwise can produce
Raw interference and destroy product itself, therefore, the liftout attachments of multiple step demouldings is set in mould inside.But in product
It is limited at surface with interior mould volume, if two Zhi Ding and oblique tops are arranged in the mould inside at lampshade panel
If, using traditional moulds, then one pedestal and two pedestals or multiple bottoms perhaps can be set for oblique top bottom on each straight top
Seat can not arrange spatial position in mold, therefore be difficult to realize the pickup of this class formation, so that the pickup of entire product becomes
It is very difficult；And in order to guarantee the smooth demoulding of product, it usually needs entire bumper could be produced by carrying out Double-ejection
Product are removed from the mold, still, if can greatly increase demoulding cost, and reduce the efficiency of demoulding using Double-ejection.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of motion stability is reliable, substep ejection can be accurately realized
Liftout attachment for bumper mold.
In order to solve the above technical problems, it includes being used for vapour provided by the present invention for the liftout attachment of bumper mold
