  • Patent number: 8752612
    Abstract: A lightweight metal mold having a necessary hardness is realized. A plurality of bar-shaped members formed of an evaporative material and a plurality of connecting members formed of an evaporative material are prepared. Each of the connecting members has a spherical shape, and ends of a plurality of the bar-shaped members can be connected to each connecting member. Since a fixing angle of each bar-shaped member with respect to the connecting member can be adjusted freely, a three-dimensional mesh structure having various shapes can be formed. By combining the plurality of bar-shaped members and the plurality of connecting members, an evaporative pattern including the three-dimensional mesh structure can be assembled. By adjusting the shape of the three-dimensional mesh structure, the hardness necessary for the metal mold can be obtained, and the metal mold can be made lighter.
