Background technology:
The edge cover strip of vehicle glass PVC hard material is a kind of section bar of injection mo(u)lding.Be cut into a section fixed length bar by designing requirement length dimension communications centre during production.And the edge cover strip shape mostly is abnormity, and existing its both sides, cross section of a kind of edge cover strip are the hypotenuse shape, and the centre is cavity, and the bottom is with outer curved raised line.Thereby be fixed on that lower module upper surface on the lower mold holder is arranged to the both sides hypotenuse, there is outer curved raised line chamber the bottom corresponding to the special-shaped cavity of edge cover strip gabarit shape during punching.Be fixed with knife module on the top mold frame, after rectangular edge cover strip is inserted in lower module abnormity cavity, stretch out lower module shear surface measured length after, upper knife module presses down along vertical guide pillar, its shearing blade face cut-out edge cover strip is finished once-through operation.For raising the efficiency, generally symmetry is fixed two lower modules on lower mold holder, fixes knife module on two in symmetry on the top mold frame.
For edge cover strip can completely be inserted in lower module abnormity cavity, and do not make the edge cover strip cover fashionable by the scratch of lower module port, so special-shaped cavity design size is larger than edge cover strip cross section gabarit.But this appropriate design is brought again problem: the gap that namely produces between edge cover strip and the special-shaped cavity easily produces otch burr, sudden and violent limit when punching.
Summary of the invention:
The purpose of this utility model is to overcome defects, and a kind of blanking die of automobile glass encapsulation bar is provided.
Scheme of the present utility model is: comprise top mold frame, lower mold holder, vertical guide pillar, two lower modules, two upper knife modules, it is characterized in that: module heavy vertical plane in place, summit under the right hypotenuse of special-shaped cavity in lower-left minute cuts out left location lower module and movable lower module as the boundary; But movable lower module two-piece unit becomes left sliding die and the base platform of translational slip, and base platform is fixed on the lower mold holder, and the base plane right part is fixed with limited block; Left sliding die upper surface and right flank angle of cut place are provided with tilt fittet, a horizontal circle pin is fixed in left sliding die left surface below, left location lower module right flank is provided with a blind hole corresponding to left sliding die horizontal circle pin orientation, a blind hole inner sleeve unification Compress Spring, left sliding die horizontal circle pin inserts in the lower module blind hole of left location movingly, its end face contacts with the Compress Spring compression type, when left sliding die left surface is fitted left location lower module right flank, special-shaped cavity chamber profile shape size and edge cover strip gabarit shape and measure-alike that the two surrounds; The bottom right module is done the symmetrical structure setting identical with the lower-left module; Top mold frame above middle position between two sliding dies is fixed a rectangle matched moulds jacking block down, matched moulds jacking block lower surface is lower than the lower surface of upper knife module, both sides, matched moulds jacking block lower surface are provided with tilt fittet, when the matched moulds jacking block contacted two sliding die sidewalls simultaneously, the special-shaped cavity of two counterdies was in the matched moulds state.
The utility model has the advantage of: lower module abnormity cavity not during matched moulds the shape chamber large, be convenient to edge cover strip and put into, can scratch.During punching, the matched moulds jacking block makes just punching behind the both sides lower modules elder generation matched moulds, and the complete identical gapless with edge cover strip contour dimension of abnormity cavity shapes during matched moulds, thereby makes punching can not produce burr, sudden and violent limit phenomenon.
Description of drawings:
Accompanying drawing is the utility model structural representation.
The specific embodiment:
The utility model comprises top mold frame 1, lower mold holder 9, vertical guide pillar, two lower modules, two upper knife modules 2, it is characterized in that: module heavy vertical plane in place, summit under the right hypotenuse of special-shaped cavity in lower-left minute cuts out left location lower module 4 and movable lower module as the boundary; But movable lower module two-piece unit becomes the left sliding die 5 and base platform 7 of translational slip, and base platform 7 is fixed on the lower mold holder 9, and the base plane right part is fixed with limited block 8; Left sliding die 5 upper surfaces and right flank angle of cut place are provided with tilt fittet, a horizontal circle pin 6 is fixed in left sliding die 5 left surfaces below, left location lower module 4 right flanks are provided with a blind hole corresponding to left sliding die 5 horizontal circle pins 6 orientation, a blind hole inner sleeve unification Compress Spring, left sliding die 5 horizontal circle pins 6 insert in lower module 4 blind holes of left location movingly, its end face contacts with the Compress Spring compression type, when left sliding die 5 left surfaces are fitted left location lower module 4 right flank, special-shaped cavity chamber profile shape size and edge cover strip gabarit shape and measure-alike that the two surrounds; The bottom right module is done the symmetrical structure setting identical with the lower-left module; Top mold frame 1 above middle position between two sliding dies 5 is fixed a rectangle matched moulds jacking block 3 down, matched moulds jacking block 3 lower surfaces are lower than the lower surface of upper knife module 2, both sides, matched moulds jacking block 3 lower surface are provided with tilt fittet, when matched moulds jacking block 3 contacted two sliding die 5 sidewalls simultaneously, the special-shaped cavity of two counterdies was in the matched moulds state.
