DIE CASTING MACHINE Russian patent published in 1994 - IPC

FIELD: foundry. SUBSTANCE: machine has fixed plate 1 movable plate 2, and frame-like plate 3 moving on columns 4 of the machine and connected by tie-rods 5 to movable plate 2. Mold has fixed half-mold 6, movable half-mold 8 and middle rotatable section 7 mounted in frame-like plate 3 on journals. Frame-like plate 3 carries rotation and fixation mechanisms of middle section 7. After opening of mold its middle section 7 turns to an angle of 180 deg and casting with pouring gate comes opposite to respective trimming holes made in movable half-mold 8. With successive closing of mold one side of middle section 7 and fixed half-mold 6 form chamber for casting, and another side and movable half-mold 8 form for cutting casting and pouring gate. Cutting off is carried out with the aid of locking mechanism which enhances operating capabilities of the machine. Middle section 7 can revolve on journals positioned both vertically and horizontally. Through one of the journals cooling fluid is fed. Employment of frame-like plate carrying rotation and fixation mechanisms makes it possible to refuse from installation of these mechanisms on each mold. EFFECT: enhanced operating capabilities, simplified design of molds. 4 cl, 6 dwg
