Abstract
A mold capable of imparting an appropriate amount of heat depending on a part of an object to be heated, the mold for transferring heat to the object to be heated is provided with a hollow portion inside the mold, and a heat amount adjusting agent, which is accommodated in the hollow portion, for changing heat transfer property of the hollow portion, in which the heat amount adjusting agent is made of a powdery or granular material having a material property different from a material property of the mold.
Claims21
A mold for transferring heat to an object to be heated comprising:
- a hollow portion provided inside the mold;
- and
- a heat amount adjusting agent held in the hollow portion for changing a heat transfer property of the hollow portion;
- wherein the heat amount adjusting agent is made of a powdery or granular material having a material property different from that of the mold.
A method for manufacturing a mold for transferring heat to an object to be heated comprising:
- forming a hollow portion inside the mold;
- forming a heat amount adjusting agent supply-discharge passage, the passage communicating between the hollow portion and outside of the mold;
- and
- accommodating a heat amount adjusting agent made of a material different from a material of the mold into the hollow portion through the heat amount adjusting agent supply-discharge passage.
A method for manufacturing a mold corresponding to a shape represented by master data, by melting and fusing together a powdery or granular material of a metal based on a plurality of slice data obtained by slicing the master data of the mold, and stacking a plurality of metallic layers each corresponding to a shape represented by each of the slice data,
- wherein part of the plurality of slice data include a region corresponding to a shape of part of a hollow portion provided inside the mold and wherein the melting and fusing together of the powdery or granular material are stopped within the region, thus leaving the same or different powdery or granular material within the region.
A tire curing mold for curing a tire by transferring heat to the tire, the mold comprising:
- a hollow portion provided inside the tire curing mold;
- and
- a heat amount adjusting agent held in the hollow portion for changing a heat transfer property in the hollow portion;
- wherein the heat amount adjusting agent is made of a powdery or granular material having a material property different from that of the tire curing mold.
