<p><P>PROBLEM TO BE SOLVED: To provide a technique for realizing at low cost, the high processing accuracy of molded articles in an electric molding processing machine. <P>SOLUTION: An electric pressing machine 1 comprises: an upper die unit 2 including an upper die 6 and an upper supported part 8; a lower die unit 3 including a lower die 9 facing the upper die 6; and a plurality of pressurizing units 4 which is installed to the lower die unit 3 and moves the upper die unit 2 relatively with respect to the lower die unit 3. Each pressurizing unit 4 is composed by including a screw shaft 17 having the upper and lower pressing parts 18 and 20, and a servomotor 12 as a driving source for moving the upper die unit 2 relatively with respect to the lower die unit 3 by driving the screw shaft 17. The upper and lower pressing parts 18 and 20 are disposed so that the upper supported part 8 of the upper die unit 2 is freely movable between the upper and lower pressing parts 18 and 20 in such a state that the upper die unit 2 is supported by the screw shaft 17. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
