Specific embodiment
It elaborates below to a kind of embodiment of segment expansion mold of the present invention.It is stated under it is emphasized that
Range and its application bright to be only exemplary, be not intended to be limiting of the invention.
Referring to Fig. 1, a kind of segment expansion mold of the present invention, including calibration sleeve 10, vacuum envelope 20, shell 30, partition 40,
The circumferencial direction of shell communication port 50, cooling liquid inlet 60 and cooling liquid outlet 70, the calibration sleeve 10 is surrounded with several axial directions
The spaced vacuum envelope 20 forms vacuum chamber 80, the calibration sleeve between each vacuum envelope 20 and the calibration sleeve 10
10 offer at least one negative pressure hole 10a by the position that the vacuum envelope 20 covers, and one end of the vacuum envelope 20 offers
Vacuum communicating hole 20a；The calibration sleeve 10 and 20 outer cover of the vacuum envelope have the shell 30,30 inward at both ends of shell
Extend and is tightly connected with the calibration sleeve 10；Partition 40, the partition 40 are equipped between the shell 30 and the calibration sleeve 10
Inner ring and the calibration sleeve 10 are tightly connected, and 40 outer ring of partition and the shell 30 are tightly connected, the partition 40 with set
There is 20 one end of the vacuum envelope of the vacuum communicating hole 20a to abut against, the end face of the partition 40 offers partition intercommunicating pore
