The temperature of warm table is adjusted to suitable value by the temperature change of material；
3) sealing strip vulcanization overlap joint
A, passing through mobile sliding block according to the angular dimension of sealing strip joint first drives the joining rod of vulcanizing press two sides to swing,
And then support rod is driven to move up and down, make the angular dimension phase of the corner dimension and sealing strip joint between two feedboards
Match；
B, then sealing strip is successively socketed on the conducting bar of feedboard and is limited, installed to the sealing strip on feedboard
It is inserted into extrusion chamber simultaneously afterwards；
C, then start hydraulic cylinder, by piston rod drive boosting block move down, make stripper plate drive extrusion molding dies into
Enter to set in hopper, continues to move down after extrusion molding dies filling sizing material, sizing material is squeezed on sealing strip joint, it is primary to pressurize
Piston rod is driven boosting block to move up after 15min by molding by hydraulic cylinder, extrusion molding dies under the action of the spring by
Decrescence small pressure, until extrusion molding dies leave vulcanization station；
4) sealing strip discharges
After to be sealed connector extrusion forming, sealing strip unification is wound by external equipment, the sizing material in extrusion chamber is by going out
Expects pipe enters in material storing box.
