First elastomeric element is for providing the first elastic stress for making the stripper be moved away from the upper mold.
Preferably, the periphery of the lower die is equipped with multiple positioning pins, central axis circumference point of multiple positioning pins around lower die
Cloth；Multiple positioning pins surround workpiece fixed area jointly.
Preferably, locating piece is additionally provided in the lower die, the locating piece is supported set on the edge of workpiece fixed area.
Preferably, the lower template is equipped with guide post, and the upper mold is equipped with guide sleeve；The guide post is movable to wear
It is connected in the guide sleeve.
Preferably, which further includes the second elastomeric element, and the second elastomeric element is set in outside punch simultaneously
It is held between upper mold and stripper；Second elastomeric element is used to provide the second elasticity for making stripper be moved away from upper mold
Stress.
Preferably, the first elastomeric element is elastic blob of viscose.
Compared with prior art, the beneficial effects of the utility model are：It is moved in upper mold towards close to lower die, that is, is molded
When, the first elastomeric element between stripper and upper mold can be compressed, and punch stretches out in the mould on the lower section and lower die of stripper
Hole coordinates, and completes punching operation；And moved far from lower die in upper mold, that is, when molding, the first elastomeric element can reset drive discharging
Plate is moved far from upper mold, and stripper is made to push up the de- workpiece sticked with punch downwards, realizes smoothly demoulding.

Specific implementation mode
In the following, in conjunction with attached drawing and specific implementation mode, the utility model is described further：
A kind of metal plate punching die as shown in Figure 1, Figure 2 and shown in Fig. 3, including upper mold 10, lower die 20, upper mold 10 can be towards
Close to either far from the movement realization molding of lower die 20 or die sinking.Multiple die holes are equipped in lower die 20, upper mold 10 is equipped with and unloads
Flitch 12 and multiple punches 11.Particularly, stripper 12 is set to the lower end of upper mold 10, and stripper 12 can towards close or
Person moves far from stripper 12.Multiple punches 11 can be corresponded with multiple die holes, make the lower end of punch 11 is movable to be connected to
The lower end of stripper 12, punch 11 can be stretched out by the lower end of stripper 12.In addition, being equipped with first between stripper 12 and upper mold 10
Elastomeric element 13, the first elastomeric element 13 is for providing the first elastic stress for making stripper 12 be moved away from upper mold 10.
On the basis of the said structure, when carrying out the punching operation of workpiece, workpiece can be placed in lower die 20, can be passed through
Die-cylinder or oil cylinder drive upper mold 10 to be moved close to lower die 20, that is, mold, in the process, stripper 12 can be with workpiece
Upper surface abuts, during 10 machinery of upper mold moves downward, the first elastomeric element 13 between stripper 12 and upper mold 10
It can be compressed, punch 11 can gradually stretch out in the cooperation of the die hole on stripper 12, with lower die 20, finally be plugged in die hole, complete
At punching operation.Hereafter, so that upper mold 10 is moved far from lower die 20, that is, mold, the first elastomeric element 13 can reset drive stripper
