Embodiment
As shown in Figure 1 and Figure 2, a kind of tetrafluoroethene lips compacting tool set, it includes mould 1；The mould 1
Including jacking block 1-4, the 1-1 of pattern one, the 1-2 of pattern two and pattern three 1-3, the 1-1 of pattern one is vertically arranged, the 1-1 of pattern one and
The 1-2 of pattern two profile is cylinder, and the 1-1 of pattern one lateral wall upper end is provided with cylindrical shoulder 1-6, the 1-1 of pattern one
Center at be provided with the cylindrical hole that communicates from the bottom to top and inverted truncated cone-shaped hole, the 1-2 of pattern two are horizontally disposed with, pattern
Two 1-2 upper surface is provided with the round ring boss 1-7 coaxial with the 1-2 of pattern two, and installation is offered in the middle part of the 1-2 of pattern two
Hole, the 1-3 of pattern three are the solid cylinder being vertically arranged, and the 1-3 lower ends of pattern three match the annulus for being sleeved on the 1-2 of pattern two
On the inside of shape boss 1-7, the matching of the 1-1 lower ends of pattern one is sleeved on the outside of the 1-2 of pattern two round ring boss 1-7, the jacking block 1-4
For annulus set, jacking block 1-4 is slidably arranged between the 1-3 outer circumference surfaces of pattern three and the 1-1 of pattern one cylindrical hole, the jacking block
The chamber formed between 1-4, the 1-1 of pattern one, the 1-2 of pattern two and the 1-3 of pattern three is tetrafluoroethene filled chamber 1-5.
