ABSTRACT:
A die casting machine in which a rotary table, mounted with a plurality of die open and close units each holding a die, is sequentially brought into association with a plurality of work stations. The die is clamped in two steps, that is, a regular die clamping and a temporary die clamping. The regular die clamping is carried out by applying the regular clamping force required by a particular injection step. The temporary die clamping is carried out by applying a clamping force which is smaller than the regular clamping force. Consequently, this die casting machine can greatly reduce the time required for the casting cycle for each product, thus providing remarkably improved productivity. Preferably, a metal cooling apparatus suitable for a rotary die casting machine may be further provided.
