Abstract
A mold includes a mold insert body made of at least two kinds of materials. The materials have different coefficients of thermal conductivity. The mold insert body includes a union part formed by sintering the materials, and the union part has a configuration set so as to correspond to a cooling way of a molding material flowed in a cavity forming part of the mold.
Claims18
A mold, comprising a mold insert body made of at least two kinds of materials, the materials having different coefficients of thermal conductivity,
- wherein the mold insert body includes a union part formed by sintering the materials, and
- the union part has a configuration set so as to correspond to a cooling way of a molding material flowed in a cavity forming part of the mold.
A mold, comprising a mold insert body,
- the mold insert body including:
- a base layer that is made of a first material;
- and
- an outermost layer that is made of a second material different from the first material of the base layer and that forms a cavity forming part,
- wherein a union part is formed by sintering the base layer and the outermost layer, and
- the union part has a configuration set so as to correspond to a cooling way of a molding material flowed in the cavity forming part of the mold.
A method for manufacturing a mold, comprising the steps of:
- a) providing a powder of a first material;
- b) providing a powder of a second material different from the powder of the first material so as to form a configuration that corresponds to a cooling way of a molding material flowed in a cavity forming part of the mold;
- and
- c) sintering the respective powders by putting the powders of the respective materials between a first electrode and a second electrode, by pressuring with a designated pressure power, and by sending a designated electric current to the powders of the respective materials.
