Abstract
A vulcanizer includes a vulcanizer body for heating a green tire by making use of heat quantity to vulcanize an mold it and repetitiously using the heating medium used for the vulcanizing and molding for heating. A heat quantity supplementing device heats the heating medium to thereby supplement a lost part of the heat quantity of the heating medium. Thereby, vulcanizing and molding can be carried out with less energy loss of the heating medium.
Claims14
A vulcanizer comprising:
- a vulcanizer body including a mold into which said green tire is charged, said mold including a segmental mold,
- a heating medium applied to said mold including said segmental mold to vulcanize the green tire;
- and
- heat quantity supplementing means for heating said heating medium to thereby supplement a lost part of a heat quantity of said heating medium,
- wherein said heat quantity supplementing means comprises a circulating channel for taking out the heating medium used for vulcanizing to outside said vulcanizer body, and a first heater provided in said circulating channel to supplement a lost part of the heat quantity of said heating medium by heating the heating medium flowing in said circulating channel.
