Description
Technical field：
It the utility model is related to technical field of mold, and in particular to one kind is used for the two-sided punching of automobile V-shaped skeleton symmetrical four
The mould in hole.
Background technology：
Be a automobile V-shaped skeleton product as shown in Figure 1, the traditional processing hole mode in the hole of product double-sided symmetrical four be
V-type skeleton is carried out before hole machined to position top and bottom drilling twice, is positioned top and bottom fraising after drilling twice again.It is lacked
Point is：Two-sided formation angle is not parallel among V-type skeleton, and positioning fraising twice again, can cause to position after positioning drilling twice
Error, cause the holes relative position inaccuracy of V-type skeleton, axiality is bad, and hole occurs among the process of assembling in client
Footpath ellipse bigger than normal, and positioning fraising twice causes production efficiency to reduce again after positioning drilling twice, relative increase production cost；
If simple counter-punching die, because the structure of product limits, difficult to punched scrap venting, cavity plate can not obtain in mould
Protection, is easily damaged；And V-type framework deformation can be caused so that the relative position in four holes shifts ellipse, ultimately result in client
Assembling goes wrong.
Utility model content：
For above-mentioned deficiency, the utility model provides a kind of mould for symmetrical four hole of the two-sided punching of automobile V-shaped skeleton,
With accurate positioning, punching precision, axiality are good, it is high in machining efficiency the characteristics of.
The utility model is as follows using technical scheme：
A kind of mould for symmetrical four hole of the two-sided punching of automobile V-shaped skeleton, including upper die and lower die；The upper mould includes
Die shank and die shank fixed plate and the punch retainer being sequentially arranged at below the die shank fixed plate, polyurethane block, binder discharging
Plate；The punch retainer is provided with two punch-pin, and the polyurethane block and binder stripper are run through in the lower end of the punch-pin；Institute
Stating lower mould includes bottom plate and workseat, cavity plate on bottom plate；Mandrel is provided with the workseat；In the workseat
Provided with stationary positioned framve, the stationary positioned framve is provided with loose pin, and the activity orientation axle lower surface is provided with activity and held in the palm
Plate, the activity pallet lower surface are provided with eccentric wheel.
Fixed backing plate and movable pad are provided with by bolt on the bottom plate, the punch-pin is arranged on the fixed backing plate
On.
The lower surface of the stationary positioned framve is connected with the bottom plate, and the activity pallet and the eccentric wheel are arranged on institute
State in stationary positioned framve.
The polyurethane block has 4 pieces.
The upper mould is provided with guide pin bushing, and the lower mould is provided with corresponding guide pillar.
Compared with prior art, the beneficial effects of the utility model are：Concave template of the present utility model passes through bolt lock
Fasten backing plate it is parallel with movable pad after be punched out, avoid because the female die of die damage bore deformation dislocation that causes to liquidate is asked
Topic；The utility model is coordinated by workseat and mandrel simultaneously, stationary positioned framve is coordinated by eccentric wheel and activity orientation axle, really
Workpiece accurate positioning has been protected, has improved precision and axiality to punching；Holes is once rushed, substantially increases production efficiency, together
When it also avoid punching twice caused by position error, improve the qualification rate of product.
Brief description of the drawings：
Fig. 1 is Workpiece structure schematic diagram of the present utility model；
Fig. 2 is mould structure schematic diagram of the present utility model；
Fig. 3 is lower die structure schematic diagram of the present utility model.
