Description

Diel with liftout attachment
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of diel with liftout attachment.
Background technology
Existing plate particularly thin plate after the punch forming, takes off relatively difficulty of material in diel.Chinese patent CN2637026Y discloses the slitter edge free automatic press mould of a kind of long-tail ticket-holder special use, comprise cope match-plate pattern and lower bolster, described cope match-plate pattern is provided with forming convax mould, limit mouth punching press punch and shears punch, described lower bolster correspondence is provided with molding concave die, limit mouth stamping cavity die and shears die, it is characterized in that described shearing punch independently is arranged on the described cope match-plate pattern, described shearing die correspondence is arranged on the described lower bolster, and the end face of described shearing punch is the edge of a knife.Use this mould, after the sheet-metal press working moulding, plate is not easy to take out from die.
Summary of the invention
The utility model mainly is to solve the technical problem that the existing mold plate is not easy to take out from die etc., and a kind of diel with liftout attachment is provided, increased a liftout attachment simple in structure, has solved the problem that mould takes off the material difficulty effectively.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: it comprises upper die and lower die and is arranged on guide pillar between the upper die and lower die, described patrix comprise upper bolster, upper padding plate, train wheel bridge, baffle plate and on take off plate, described upper bolster, upper padding plate, train wheel bridge, baffle plate and on take off plate and be arranged in order from top to down, described counterdie comprises lower bolster, lower bolster and die shoe, the guide pillar upper end is with guide column sleeve, described counterdie is provided with a die cavity, is provided with the elasticity liftout attachment of an automatic material jacking in the described die cavity.After punching press was finished, when patrix left counterdie, the elasticity liftout attachment ejected the plate of forming automatically, thereby had solved the problem of mould separating difficulty.
As preferably, described elasticity liftout attachment comprises die piece and the ejector spring that is arranged on die piece bottom, is provided with the screw and the swivel nut that connect die piece and ejector spring between described die piece and the ejector spring.The die piece is used for the moulding of plate.When patrix withstands counterdie, the ejector spring compression, after moulding was finished, when patrix left counterdie, ejector spring resetted, and plate is ejected from die cavity.
As preferably, described patrix is provided with the punching pin that a plurality of stamping-outs are used.Punching pin acts directly on the plate, is used for the moulding of plate, as punching or side cut etc.
As preferably, be respectively equipped with a plurality of pins that are used for fixing mould on the described upper die and lower die.
As preferably, described guide pillar is arranged on four jiaos of diel.
As preferably, be with balancing spring on the described guide pillar.
As preferably, described guide pillar is provided with some hoodles, forms the hoodle face that contacts with guide column sleeve in the guide pillar upper end.
The utility model uses hoodle to be connected at guide pillar and guide column sleeve contact-making surface, has adopted multiple spot to contact and has replaced the contact of former face, makes frictional force reduce greatly, thereby has avoided the wearing and tearing of guide pillar.
As preferably, leave partition adjustable between described train wheel bridge and the baffle plate.Certain cushioning effect is played in the setting of partition adjustable, and before stamping press reaches maximum, for the timely adjusting module position of director element provides the regular hour assurance.
The beneficial effect that the utility model brings is that the utility model has increased a liftout attachment simple in structure, has solved mould effectively and has taken off the difficult problem of material.
