The working principle and process for using of the utility model: the stamping die for being used to prevent upper/lower die from shifting is in reality
In use, first by bottom plate 1 by being fixedly connected between the screw hole slot 2 and punching press table top of its two sides edge, and guarantee bottom
Horizontal state is kept between plate 1 and punching press table top, then by the knob 20 of 14 side middle-end of shaping mould base by shaping mould
Seat 14 is inserted into mounting groove 13, when shaping mould base 14 is inserted into mounting groove 13, passes through 14 two sides edge of shaping mould base
The grafting between slot 16 opened up inside inserted block 17 and mounting groove 13, enables shaping mould base 14 to be fast and accurately inserted into peace
In tankage 13, the accuracy of position upon connection is guaranteed between mounting groove 13 and shaping mould base 14 with this, and when inserted block 17 is inserted into
After in slot 16, the limited block 19 on 17 bottom end of inserted block and top will be with the limiting slot 18 of slot 16 bottom end and top at this time
Between agreed with, and then guaranteed by the limit between limited block 19 and limiting slot 18 shaping mould base 14 and mounting groove 13 it
Between the phenomenon that not generating positional shift in subsequent punching course, after shaping mould base 14 is completely inserted into mounting groove 13,
Turn fixing bolt 21 at this time is further carried out the connection between shaping mould base 14 and mounting groove 13 by fixing bolt 21
It is fixed；
After the fixed installation of shaping mould base 14, the molding core cavity 15 that part to be punched is placed in inside shaping mould base 14
It is interior, after part is placed in molding core cavity 15, the guide post 9 of 11 bottom end of backform is inserted into the embeded slot 5 inside guide sleeve 4, and is made
It is in close contact between the bottom end of guide post 9 and the platen 8 inside embeded slot 5, and when guide post 9 is inserted into embeded slot 5, lead to
Guiding sliding between the guide chute 6 that the guide runner 10 and 5 inside edge of embeded slot for crossing 9 outside edge of guide post open up, energy
It enough prevents the position between guide post 9 and embeded slot 5 in punching press from generating displacement, and then guarantees 12 energy of upper die holder of 11 bottom end of backform
Pressing is enough accurately carried out between lower die holder 3 to contact, and guarantees the stamping quality of part with this；
In practical punching press, the compression leg of the press such as hydraulic press is placed in the middle-end of backform 11, is mentioned by hydraulic press
For the pressure of punching press, when backform 11 pushes, by the pressure-bearing spring 7 of 5 inner lower edge of embeded slot can to the pressure of punching press into
Row buffering, and then prevent stamping pressure from crossing and generate damage between ambassador's upper die holder 12 and lower die holder 3, shaping mould base is guaranteed with this
The quality of 14 inner body die casts, and can be incited somebody to action in punching course by the heat dissipation through slot 22 of 3 two sides edge of lower die holder
The heat that generates discharges when shaping mould base 14 and molding 15 inside punching press of core cavity, while by heat-conducting silica gel sheet 24 come into one
Step improves the heat dissipation effect of heat dissipation through slot 22, can be avoided inside molding core cavity 15 with this and the phenomenon that thermal reservoir occurs, avoids
The phenomenon that excessively high edge for making part after forming of molding 15 internal heat of core cavity generates carbonization；
After in entire punching course, it will be separated between the guide post 9 of 11 bottom end of backform and guide sleeve 4, and make upper die holder
It is separated between 12 and lower die holder 3, then loosens fixing bolt 21, draw shaping mould base 14 out of mounting groove 13 by knob 20
Out, the part after die casting can quickly be dismantled convenient for staff with this, and then improves the working efficiency of mold.
Finally, it should be noted that being not limited to this reality the foregoing is merely the preferred embodiment of the utility model
With novel, although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it is still possible to modify the technical solutions described in the foregoing embodiments, or to part of technical characteristic into
Row equivalent replacement.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on, should all
It is included within the scope of protection of this utility model.
