Claim 12:
13. A control device for a die casting machine, configured to control a machine body in a die casting machine wherein a mold opening/closing direction is inclined at an angle less than 45° relative to a horizontal direction or is arranged in the horizontal direction and a plunger driving direction is inclined at an angle less than 45° relative to the horizontal direction or is arranged in the horizontal direction, comprising:
a gap control part configured to control the machine body so as to make mating surfaces of a pair of dies face each other across a gap, and thereby a cavity in the pair of dies and an external part of the pair of dies are communicated across the gap;
a molten metal feed control part configured to control the machine body so as to feed molten metal into a sleeve communicated with the cavity while the gap is being maintained;
an injection control part configured to control the machine body so as to start a forward movement of a plunger in the sleeve toward the pair of dies while the gap is maintained and there is the molten metal in the sleeve; and
a clamping control part configured to control the machine body so as to make the mating surfaces abut against each other to eliminate the gap after a start of the forward movement of the plunger and before arrival of the molten metal at a molten metal surface height at which the molten metal flows into the gap.
