Description
Technical field
The present invention relates to technical field of mold, specifically a kind of notch die of rear-suspending mounting bracket.
Background technology
Automobile die refers to the mould being applied to automotive field, the title that automobile die have " mother of auto industry ", in automobile production, the parts of more than 90% need to rely on die forming, Auto panel dies is big-and-middle-sized cladding member mold particularly, being the important component part of Auto-body manufacturing technology, is also the key link forming automobile ability to develop independently.
The production mould of rear-suspending mounting bracket is one of mould important in automobile die; but part rear-suspending mounting bracket often there will be engine rightmost support breakdown phenomenon, gently then disconnects a crack, heavy then support all disconnects and coming off; cause engine to sink, drive disk assembly damages.
The position of rear-suspending mounting bracket cracking is mostly from the knuckle of support, because sheet-metal press working part is all firmly more crisp, knuckle is under the effect of alternate stress, more easily crack, when automobile normal running, rear suspension bracket is subject to the pulling force effect that engine gravity and engine tilting moment produce, when vehicle starting, engine, by the tractive of payload mass, produces front and back play; When running car is at uneven road surface or washboard pavement, make the upper and lower play of engine equally, support under tension or pressure effect, if support cracks when punching press, stress can be caused to concentrate, and crackle extends gradually, until last breakdown.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of notch die of rear-suspending mounting bracket.
The present invention solves its technical problem and realizes by the following technical solutions:
A kind of notch die of rear-suspending mounting bracket, comprise lower bolster, be provided with lower bolster on front side of described lower bolster upper surface, on rear side of lower bolster upper surface, be bolted lower limit post, be provided with left guide pillar on the left of lower bolster upper surface, on the right side of lower bolster upper surface, be provided with right guide pillar; Described lower bolster upper surface is provided with the sliding plate for being derived by waste material, and lower bolster upper surface is also provided with cushion block and counterdie; Described cushion block inside is cavity, and cushion block is enclosed within outside sliding plate, plays the effect of protection counterdie inwall; Described counterdie inside is also cavity, and lower die-sleeve is outside cushion block, the cavity upper end of counterdie inside is provided with the counterdie mold insert be closed by the cavity of counterdie inside, and simultaneously counterdie mold insert also plays the supporting role to part, thus is convenient to drift and more stably carries out blanking to part; The middle part of described counterdie mold insert is provided with through hole; Be provided with drift in described through hole, and the lower surface of drift is inclined-plane, to utilize the blade of drift to carry out blanking to part top more tartly, reduces the impulsive force that drift produces part, thus reduce the stress concentration phenomenon that part produces; On the upside of described drift, cover has the holding pad for being pressed on by part on counterdie; Described holding pad is placed on counterdie top, and the rear portion of holding pad is provided with the binder recess corresponding to counterdie rear end profile so that holding pad is before and after produce with counterdie because of binder during relative displacement, holding pad can not under be molded as interference; Be provided with upper mounted plate above described holding pad, and upper mounted plate fixed cover is in the upper end of drift; Fixed plate upper end is provided with upper padding plate; Described upper padding plate upper end is provided with cope match-plate pattern; The lower surface, right side of described cope match-plate pattern is provided with right guide pin bushing, be provided with on rear side of lower bolster lower surface with lower limit post with the use of upper limit post.
Described lower limit post and upper limit post are quadrangular shape, to increase the contact area of lower limit post and upper limit post, thus improve the spacing stability of upper limit post and lower limit post.
Described sliding plate is voussoir shape, will be skidded off by sliding plate in time by drift institute junk material, avoids material in cushion block inner accumulated, affects blanking again; The lower rearward side of described cushion block is provided with a recess, and a recess is across above sliding plate; Described counterdie lower rearward side is provided with No. two recesses, and No. two recesses are also across above sliding plate, and No. two recesses are identical with the size of a recess, and No. two recesses and a recess are avoided interfering lubricating substance block to get rid of junk material.
Described counterdie is enclosed within outside cushion block by the mode of mortise-tenon joint; Described counterdie mold insert is also fixed on counterdie upper end by the mode of mortise-tenon joint, and the mode of mortise-tenon joint is conducive to the stability of raising parts connection, fastness and connection precision.
The upper surface of described sliding plate and the angle of horizontal plane are not less than 30 °, and angle is crossed young pathbreaker and caused being rushed the waste from stacking that falls on sliding plate upper surface, can not give play to the effect of sliding plate, affect follow-up matched moulds process.
The invention has the beneficial effects as follows: reasonable in design of the present invention, is connected firmly, supporting & stablizing; The setting of upper limit post, lower limit post and left guide pillar, right guide pillar, improves compression accuracy and the stability of mould from two-dimensional space; Arranging of cushion block provides protection to counterdie, reduces cost of equipment maintenance; The support being set to part of counterdie mold insert provides guarantee, and because counterdie mold insert is expendable part, the counterdie mold insert be separated with counterdie is also beneficial to the replacing of counterdie mold insert, reduces cost of equipment maintenance; The drift that lower surface tilts can slow down the impulsive force of drift to part, is more conducive to the blanking of drift to part, thus is effectively reduced in blanking operation the concentrated effect of stress that part is formed.
