Abstract
The utility model relates to a kind of mould, be specially synchronous binder discharging blanking die, comprise upper die and lower die, described patrix comprises upper clamping plate, punch retainer is connected and fixed by convex mould pad below upper clamping plate, be discharging backing plate and stripper below punch retainer, stripper is arranged on patrix by discharging spring, sleeve, also comprise activity discharging briquetting, activity discharging briquetting is in stripper die cavity, connect lower push rod, upper ejector pin successively above activity discharging briquetting, linking springs on upper ejector pin, spring is fixed in upper clamping plate by plug screw; By punch fixed block solid punch in the die cavity of described punch retainer.This synchronous binder discharging blanking die, the thinning region of product first pushed down by activity discharging briquetting, then stripper pushes down other region of product, last punch carries out stamping-out, product expects binder and discharging simultaneously on thick place pressing direction in difference, thus prevent from being out of shape during weakened region stamping-out, ensure that the precision of Product processing.
Description
Technical field
The utility model relates to a kind of mould, is specially synchronous binder discharging blanking die.
Background technology
The process layout of the thinning series products of regional area on stepping punching mould becomes essence cut for first thinning to do again, ensures the dimensional tolerance of weakened region shape with this.This thinning rear product in product local is by generation two kinds of thickness, follow-up essence is cut and one-step punching is crossed over two kinds of thickness, easily produces buckling deformation, affects Product Precision, the one-tenth-value thickness 1/10 thinning due to the local of different product is different, and therefore the unloading insert block press material structure of fixed dimension cannot fix product.
Utility model content
For above-mentioned technical problem, the utility model provides a kind of blanking die, can prevent the deformation of products that in blanking process, local thins.
Concrete technical scheme is:
Synchronous binder discharging blanking die, comprise upper die and lower die, described patrix comprises upper clamping plate, punch retainer is connected and fixed by convex mould pad below upper clamping plate, be discharging backing plate and stripper below punch retainer, stripper is arranged on patrix by discharging spring, sleeve, also comprise activity discharging briquetting, activity discharging briquetting is in stripper die cavity, lower push rod, upper ejector pin is connected successively above activity discharging briquetting, linking springs on upper ejector pin, spring is fixed in upper clamping plate by plug screw; By punch fixed block solid punch in the die cavity of described punch retainer.
The synchronous binder discharging blanking die that the utility model provides, the thinning region of product first pushed down by activity discharging briquetting, and then stripper pushes down other region of product, and after product compresses, punch carries out stamping-out.Because product expects binder and discharging simultaneously on thick place pressing direction in difference, thus material deformation when preventing weakened region stamping-out, ensure that the precision of Product processing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
By reference to the accompanying drawings, specific embodiment of the utility model is described.As shown in Figure 1, synchronous binder discharging blanking die, comprise upper die and lower die, described patrix comprises upper clamping plate 1, punch retainer 3 is connected and fixed by convex mould pad 2 below upper clamping plate 1, be discharging backing plate 4 and stripper 5 below punch retainer 3, stripper 5 is by discharging spring, sleeve is arranged on patrix, also comprise activity discharging briquetting 16, activity discharging briquetting 16 is in stripper 5 die cavity, lower push rod 14 is connected successively above activity discharging briquetting 16, upper ejector pin 13, linking springs 12 on upper ejector pin 13, spring 12 is fixed in upper clamping plate 1 by plug screw 11, by punch fixed block 15 solid punch 17 in the die cavity of described punch retainer 3.
Patrix is activity discharging briquetting 16 region that first contact product 6 is thinning when descending, and the binder strength of activity discharging briquetting 16 is provided by spring 12; Patrix continues other region that descending stripper 5 pushes down product 6, and the pressure of stripper 5 is provided by discharging spring, sleeve, and after product 6 compresses, patrix continues downwards, and punch 17 carries out stamping-out.
Lower push rod 14 utilizes punch retainer 3 spacing, and upper ejector pin 13 utilizes convex mould pad 2 spacing.
