Abstract

PURPOSE:To control the die temp. during charging to optimum temp. and to prevent the production of defectives by stopping water feeding at the temp. determined by adding the difference between the optimum temp. of the dies of this time and the temp. at the charging to the die temp. at the previous stopping of the water feeding. CONSTITUTION:When molten metal is charged into dies 1, the die temp. rises, and cooling water is supplied to the dies 1 at a water feed temp. TON. Thereafter the die temp. rises up to a prescribed temp. TMAX and begins to lower; during this time, dies are opened, and the casting is removed; at the temp. TOFF, the water feeding is stopped. At this time, the die temp. lowers further at the temp. TMIN', again the molten metal is charged into the dies 1, and at the water feed temp. TON', the water is fed. The temp. rises up to the prescribed temp. TMAX' and lowers, and during this time, the casting is removed. At this time, the time for stopping is made faster than the time TOFF for the previous water feeding by as much as the differential temp. TOBJ-TMIN at which the die temp. TMIN during charging went too low with respect to the target temp. TOBJ, and the water feeding is stopped at the time TOFF'. In some cases, the time temps. TMIN, TMIN' during charging are higher than the target temp. TOBJ.
