REFINING DEVICE AND METHOD

PROBLEM TO BE SOLVED: To provide a refining device capable of more efficiently performing raw material refining. SOLUTION: A die 10 in the refining device comprises four molding holes 11 to 14 crossed at the intervals of 90° and a crossing chamber 19 formed at the crossed parts thereof. Molding pins 22, 24 inserted into the molding holes are moved forwards and backwards, thus raw materials such as magnesium alloy chips are refined. In the refining stage, the raw materials are stored into the molding hole 11, the molding pins are pushed therein to compact the raw materials, thereafter, the molding pins are progressed as being further pressurized, and the molding pin 22 is retreated in a state where back pressure is applied, thus the raw materials are fed from the molding hole 11 to the molding hole 12. A pair of projecting parts 26c are formed at the front edge part of the molding pins, so as to reduce a dead space in the crossing chamber 19. COPYRIGHT: (C)2007,JPO&INPIT
