Title:
COMPONENT FOR EVAPORATIVE PATTERN AND EVAPORATIVE PATTERN
Document Type and Number:
WIPO Patent Application WO/2012/101828
Kind Code:
A1
Abstract:
The present invention yields a lightweight mold provided with requisite rigidity. A plurality of rod-shaped members formed from an evaporative material and a plurality of connecting members formed from an evaporative material are prepared. Each of the connecting members is spherical, and end sections of the plurality of rod-shaped members can be secured to a single connecting member. The angle at which the rod-shaped members are secured to the connecting member can be adjusted as needed; therefore, three-dimensional mesh structures having a variety of shapes can be formed. An evaporative pattern provided with a three-dimensional mesh structure can be manufactured by combining the plurality of rod-shaped members and the plurality of connecting members. Performing full mold casting using the evaporative pattern makes it possible to manufacture a mold provided with a three-dimensional mesh structure. Adjusting the shape of the three-dimensional mesh structure makes it possible to obtain the requisite rigidity for the mold and reduce the weight of the mold.
