Abstract
Tire mold subject to least energy loss from heat dissipation during a curing process and thus capable of improving a curing efficiency, the tire mold has hollow cavities therein and a heating medium that circulates inside the hollow cavities, thereby heating a tire through the mold.
Claims17
A tire mold for curing a tire by transferring heat to the tire, comprising:
- a hollow cavity formed inside the tire mold;
- and
- a heating medium held inside the hollow cavity and heating the tire via the tire mold.
A method for manufacturing a tire mold by curing a tire by transferring heat to the tire, the method comprising the steps of:
- forming a hollow cavity inside the tire mold;
- and
- forming heating medium supply/discharge channels communicating with the hollow cavity and outside of the tire mold.
A method for manufacturing a tire mold comprising:
- melting and fusing metal powder according to a plurality of slice data, which are master data of a base mold and a pattern mold sliced;
- and
- laminating a plurality of metal layers according to the shape represented by the respective slice data, thus molding the base mold and the pattern mold into the shapes represented by the respective master data,
- wherein part of the plurality of slice data of the master data of the base mold and the pattern mold contain regions corresponding to shapes of part of hollow cavities formed inside the base mold and the pattern mold, and the melting and fusion of the metal powder are stopped within the regions so as to form the hollow cavities communicating with heating medium supply/discharge channels.
