ABSTRACT:
A process and an apparatus for manufacturing a cast product in which the cavity 2c is defined by a top die 1, a bottom die 2 and a slidable die insert 11 relative to the top die 1 and a pressure is applied to the die insert 11 by a hydraulic cylinder 13 before casting, injecting a molten metal 6 at a pressure higher than that on the die insert 11 to cause the die insert 11 to move rearward, whereby the molten metal 6 is additionally filled in the cavity 2c by an amount corresponding to the shrinkage due to pressurization, and a pressure on the molten metal 6 within the cavity 2c is maintained through the die insert 11 even after the molten metal 6 in the gate 2b has been solidified and the injection pressure has: not been transmitted anymore.
