Document Type and Number:
WIPO Patent Application WO/2019/163188
Kind Code:
A1
Abstract:
In order to provide a bending mold capable of producing a product without buckling, even if the product shape is long or the shape freely bends three dimensionally in space, this bending mold 1 has a smooth shape formed as a result of continuously virtually moving, inside a three-dimensional space, a profile 5 including a substantially circular first closed curve C1 having a recess. The bending mold is characterized by: the opening width b of the recess being shorter than the groove width a of the recess; a tube fitting section 2 being formed by the recess; and said shape being realized and created in real space by using three-dimensional printing.
