Secondary to be arranged in the lower bolster and lower template, the back-moving spring is arranged in the die shoe and lower bolster successively；
The floating pin includes head and body portion, and the head is mutually supported with corresponding back-moving spring, and the body portion opens up
There is groove, and the bottom in the body portion is provided with one section of boss, and the height of the boss is arranged to 0.2 ~ 0.5mm, described convex
The length of platform is less than the half of the diameter of the floating pin.
Wherein, the height of the boss is arranged to 0.3mm.
Wherein, the upper surface of the boss is parallel with horizontal plane.
Wherein, the die shoe is fixed in one end of the back-moving spring by screw locking, the back-moving spring it is another
One end and the head of the floating pin are mutually supported.
Wherein, the die shoe and lower bolster correspondingly offer spring eye, and the lower bolster and lower template correspondingly offer
Buoyance lift pin-and-hole, the head of the floating pin are arranged in the spring eye, and the body portion of the floating pin is arranged in the buoyance lift pin-and-hole.
Wherein, several described floating pins are arranged side by side.
The beneficial effects of the utility model are：
A kind of floating pin of the present utility model diel not easy to break, including upper bolster and die shoe, upper bolster by
Upper padding plate, train wheel bridge, upper baffle plate and up stripper, die shoe are up to disposed with down is disposed with underlay from the bottom to top
Plate and lower template, in addition to several floating pins and be arranged in down successively with the one-to-one back-moving spring of floating pin, floating pin
Backing plate and lower template, back-moving spring are arranged in die shoe and lower bolster successively；Floating pin includes head and body portion, head with it is corresponding
Back-moving spring mutually support, body portion offers groove, and the bottom in body portion is provided with one section of boss, and the height of boss is arranged to
0.2 ~ 0.5mm, the length of boss are less than the half of the diameter of floating pin.Compared with prior art, floating pin of the present utility model
Using said structure, stress point is concentrated on boss, the bottom stress of floating pin is avoided, so that floating pin is less likely to occur
Fracture, avoids exploding mould, therefore, greatly promotes the safety and stability of mould, is advantageous to improve production efficiency.

Embodiment
The utility model is further described with the following Examples.
A kind of diel not easy to break of floating pin of the present embodiment, it is shown as shown in Figure 1, Figure 3 and Figure 4, including upper bolster 1
With die shoe 6, upper bolster 1 is from top to bottom disposed with upper padding plate 2, train wheel bridge 3, upper baffle plate 4 and up stripper 5, lower mould
Seat 6 is disposed with lower bolster 7 and lower template 8 from the bottom to top, in addition to several floating pins 10 and with a pair of floating pin 10 1
The back-moving spring 9 answered, floating pin 10 are arranged in lower bolster 7 and lower template 8 successively, and back-moving spring 9 is arranged in the He of die shoe 6 successively
Lower bolster 7；Floating pin 10 includes head and body portion, and head is supported with the corresponding phase of back-moving spring 9, and body portion offers groove 102,
And the bottom in body portion is provided with one section of boss 101（See Fig. 4）, the height of boss 101 is arranged to 0.2 ~ 0.5mm, boss 101
Length is less than the half of the diameter of floating pin 10.Floating pin 10 uses said structure, stress point is concentrated on boss 101, avoids
