Abstract
In a center mechanism of a tire vulcanizing machine equipped with four kinds of hydraulic cylinders, lower end portions of a plurality of rods are made insertable into holes provided in a beam to transmit a pressing force generated by a pressurized hot medium to stoppers through the respective rods upon vulcanization of a tire. Upon completion of vulcanization of the tire, the stoppers are made to swing to lower the respective rods.

A center mechanism of a tire vulcanizing machine, comprising:
- a lower tire vulcanizing mold having a central portion;
- a lower ring member mounted so as to be moveable into and out of said central portion of said lower mold, said lower ring member having a plurality of vertically extending rods connected thereto;
- and
- hydraulic cylinder means comprising a plurality of hydraulic cylinders for moving said lower ring member into said central portion and raising said rods upon vulcanization of a tire, and moving said lower ring member out of said central portion and lowering said rods upon completion of the vulcanization of the tire, wherein said hydraulic cylinder means further comprises pivotably mounted stoppers below said rods for supporting said rods upon vulcanization of the tire and pivoting upon completion of the vulcanization of the tire to allow said rods to be lowered.
