Summary:The uniaxial press mold mass-produces precise ceramic balls and easily eliminates air when forming the ceramic balls. The press mold comprises: semi spherical forming parts(22,24) installed at ends of die insertion parts(18,20); an upper punch(22), installed within the die insertion part(18), having an air passing member(38); a lower punch(14) having the die insertion part(20) and the forming part(24); a die(16) having a U shape passageway(26) making the die insertion part(18) of the upper punch(12) inserted into, and a linear passage way(26') making the die insertion part(20) inserted into. The diameter of the die insertion part(18) is the same as that of the ball forming body(40), and the diameter of the other die insertion part(20) is 40-60 % of the ball forming body(40). 내용없음
