Title: Stack-molded die and producing method therefor

IPC: B22F3/105
Filed: 2006-10-20
Abstract: <P>PROBLEM TO BE SOLVED: To produce a molded article having a three-dimensional structure of a large contour with high precision, by reducing the warp of a base plate and preventing the distortion of the contour.  <P>SOLUTION: When layers 2 to be hardened are stacked on the base plate 22 to form a desirable molded article 5, the volume decreases because spaces among powders are lost while the layers 2 to be hardened are sintered, and furthermore, a contraction stress 110 is generated inside the molded article 5 by solidification shrinkage. The molded article 5 is tentatively bonded with the base plate 22 and causes the volume shrinkage, so that a reaction force 111 acts in the base plate 22 due to a tensile force. When the contraction stress 110 is larger than the reaction force 111, the base plate 22 is warped and causes distortion in the three-dimensional shape formed thereon. The production method includes forming a notch 6 on the surface which is located in the lower part of the molded article 5 and contacts with the base plate 22. Then, the notch reduces a contacting area between the base plate 22 and the molded article 5, decreases a bending moment caused by the shrinkage, makes a balance between the contraction stress 110 and the reaction force 111 advantageous to the base plate 22, suppresses the warp of the base plate 22, and accurately forms the molded three-dimensional shape.  <P>COPYRIGHT: (C)2008,JPO&INPIT
