SELECTIVELY HITTING PRESS MOLD DEVICE CAPABLE OF PREVENTING NOISE DUE TO CONTACT OF A GUIDE PLATE AND A LOWER MOLD WHEN AN UPPER MOLD RISES

摘要

PURPOSE: A selectively hitting press mold device is provided to enable a target to be smoothly molded since pressure generated by downward movement of a press slide is supplied to an upper mold through hitting between hitting plates with instantaneous great force.;CONSTITUTION: A selectively hitting press mold device comprises upper and lower molds(200,100), upper and lower hitting plates(500,400), a press slide(300) and a common plate(600). The upper mold is installed on the upper end of the lower mold and moves up and down. The lower hitting plate is mounted on the top of the upper mold and is slid in a horizontal direction. The top of the lower hitting plate is formed in an uneven structure. The press slide periodically pressurizes the upper mold. The common plate makes tight contact with the bottom of the press slide and is formed to be larger than the lower hitting plate.;COPYRIGHT KIPO 2012
