Claim 0:
1. A die casting machine comprising:
a clamping device configured to perform opening, closing, and clamping of a pair of dies, wherein a mold opening/closing direction of the clamping device is inclined at an angle less than 45° relative to a horizontal direction or is arranged in the horizontal direction;
an injection device configured to make a plunger move forward in a sleeve communicated with a cavity between the pair of dies to thereby inject a molten metal into the cavity, wherein a plunger driving direction of the injection device is inclined at an angle less than 45° relative to the horizontal direction or is arranged in the horizontal direction;
a molten metal feed device configured to feed the molten metal into the sleeve; and
a control device configured to control the clamping device, the injection device, and the molten metal feed device, wherein
the control device comprises:
a gap control part configured to control the clamping device so as to make mating surfaces of the pair of dies face each other across a gap, and thereby the cavity and an external part of the pair of dies are communicated with each other across the gap,
a molten metal feed control part configured to control the molten metal feed device so as to feed the molten metal into the sleeve while the gap is being maintained,
an injection control part configured to control the injection device so as to start a forward movement of the plunger while the gap is maintained and there is the molten metal in the sleeve, and
a clamping control part configured to control the clamping device so as to make the mating surfaces abut against each other to eliminate the gap after start of the forward movement of the plunger and before the molten metal has reached a molten metal surface height at which the molten metal flows into the gap.
