Abstract
PURPOSE: To form a die cast produce having a superior damping effect by quenching a product taken out of dies at a specified temp. after die clamping, pouring and compressing processes.
CONSTITUTION: A movable die 2 is moved toward a fixed die 1, the opposite faces 1b, 2b are brought into press contact with each other to clamp the dies together, and molten metal is poured into the casting part 3 formed with the casting faces 1a, 2a by means of an injector. When the solidification of the poured molten metal 4 proceeds toward the center of the part 3, and below holes due to sucked air and blow holes due to the residual gas as well as shrinkage cavities begin to occur at the central part, by rotating a cam 5b, the body 2" is moved in the moving direction of the die 2. The face 2a compresses the semisolid product 17 to remove the blow holes 16, etc. and to exhaust the gas from the venting path 15. This state is held until the product 17 is solidified. The solidified product 17 is taken out of the dies at a temp. corresponding to 43W50% of the melting temp. of the poured metal, and it is quenched to ≤17°Cin a moment by putting in water. Thus, the structure is made extremely fine, and the damping effect is enhanced.
