<p>The present invention relates to a mold device for an enhanced EE core to increase productivity by producing two sheets of an upper and a lower E-shaped cores at once as the allowed horizontality and size between the left and right legs and a center leg of the upper E-shaped core (1, 2, 3) is within 0.02, and obtain uniform quality during mass-production as lo characteristics are the same or higher than its exiting method. Hard punches (33) are installed in an upper holder (30) of a press by ejecting pin pilots (32) and a punch fixating plate (31). The two ejecting pin pilots (32) are installed on the lower and upper E-shaped cores placed on a fixating block (38) at constant intervals. A movable stripper (34) is installed in the ejecting pin pilots (32) of the upper holder (30) and the hard punches (33) of the punch fixating plate (31). A guide plate (35) of a pilot ball spring (36) as a bearing spring bolt is installed in a blanking die, and a strip (37) and the hard fixating block (38) are installed next thereto.</p> |
