Abstract
The invention provides a stamping die for a lower reinforcing plate of an automotive windscreen wiper. The reinforcing plate can be smoothly ejected after being stamped, and meanwhile, influence on the flatness of the reinforcing plate is avoided. The stamping die comprises an upper template and a lower template, which are connected through a guide pillar and a guide sleeve. An upper die structure is arranged below the upper template. A lower die structure is arranged on the lower template. The stamping die is characterized by comprising an ejection structure, wherein the ejection structure comprises an indirect ejection plate, an ejection plate, a stirring screw, a first connecting pin and a second connecting pin, wherein the indirect ejection plate is positioned below the upper template; the first connecting pin is arranged between the indirect ejection plate and the upper template; the ejection plate is arranged below the indirect ejection plate; and the second connecting pin and the stirring screw are arranged on the left and right sides of the indirect ejection plate and the ejection plate respectively.
Description
Technical field
The present invention relates to the punch process field of auto parts and components, relate in particular to wiper lower reinforcing plate processing unit (plant) technical field, be specially the diel of wiper lower reinforcing plate.
Background technology
The windscreen wiper lower reinforcing plate as shown in Figure 1 and Figure 2, it adds man-hour at blanking, for subsequent forming is processed the location consideration of its stiffener in mould, can position to stiffener the stamping-out in hole 30 in blanking processing, after stiffener punching moulding, patrix separates with counterdie, and stiffener easily is stuck on drift; Some stamping dies adopt thimble that it is ejected, but because thimble hardness is high, can stay the marking on the stiffener surface, and after the stiffener stamping-out, its flatness is bad.
Summary of the invention
For the problems referred to above, the invention provides the diel of wiper lower reinforcing plate, can smoothly stiffener be ejected after its punch process, simultaneously, guarantee to ring its flatness unaffected.
its technical scheme is such, the diel of wiper lower reinforcing plate, it comprises cope match-plate pattern and lower bolster, described cope match-plate pattern and described lower bolster pass through guide pillar, guide pin bushing connects, under described cope match-plate pattern, upper die structure is installed, on described lower bolster, lower die structure is installed, it is characterized in that: it comprises ejecting structure, described ejecting structure comprises indirect top board, top board, the material toggling screw, connecting pin one and connecting pin two, described indirect top board is positioned at below described cope match-plate pattern, between itself and described cope match-plate pattern, described connecting pin one is installed, described mounting of roof plate is in described indirect top board below, described indirect top board and the described top board left and right sides are separately installed with described connecting pin two and material toggling screw.
It is further characterized in that:
Described upper die structure comprises drift, die, upper mounted plate, upper padding plate and hollow backing plate, described die is fixed under the fixed plate, the fixed plate is installed under described upper padding plate, described upper padding plate is installed under described hollow backing plate, described indirect mounting of roof plate is in described its groove of hollow backing plate, described mounting of roof plate is in its groove of described die and have pilot hole, and described drift is fixed under the fixed plate and passes through its pilot hole of described top board;
Described lower die structure comprises punch-die, bottom plate, lower bolster and stripper, described punch-die is fixed on described bottom plate, described stripper is installed on described bottom plate, and described bottom plate is installed on described lower bolster, and described lower bolster is installed on described lower bolster;
Between below, described stripper left side and described bottom plate, pin stop is installed, described pin stop is connected by spring with described bottom plate.
After adopting the present invention, its beneficial effect is: after stiffener punching moulding, upper die structure and lower die structure separate, and top board extrudes stiffener under the effect of its deadweight and indirect top board from drift, because top board acts on whole stiffener upper surface, do not affect its surface planarity of stiffener, simultaneously, before top board and stiffener separate, top board is pushed down stiffener all the time, guarantees that further the stiffener surface planarity is good.
