Iron, the cavity plate housing are internally provided with cavity plate, and the upper surface setting of the cavity plate is fluted, and the punch-pin is placed on cavity plate
On, the bottom surrounding of the punch-pin is provided with protruding block, and the protruding block is stuck in groove, and the punch-pin is mounted on upper die holder
On, fixed column is provided on the upper die holder, the fixed column is fixed on outside cavity plate across upper die holder and puts on.
Preferably, there are four the fixed columns, and four fixed columns equidistantly distribute on upper die holder.
Preferably, the fixed column is cylindrical structure.
Preferably, there are two the parallels, and two parallels equidistantly distribute outside cavity plate on set.
Preferably, the bottom surface of the protruding block is set as convex structure, and the bottom portion of groove is also convex structure.
Preferably, it is provided with circular hole on the upper die holder.
Compared with prior art, the utility model has the beneficial effects that：After the utility model installs, fixed column can be with
Play the role of a support to punch-pin, prevents the punch-pin caused by punch-pin long-term motion from dislocation occurs and is made caused by tilting
There are the possibility of overlap, protruding block is mutually matched member with groove provided around cavity plate provided around punch-pin, can be prevented
Cavity and core be made caused by shifting part there are overlap can performance, on the other hand, protruding block and groove can also
The correct position for calibrating cavity and core, reduces the probability of overlap, the utility model is scientific and reasonable for structure, safe and convenient to use.
