The present invention provides a die casting machine which can shorten the melting time of metal in a sleeve, shorten the melting efficiency and reliably supply metal into the sleeve thereby increasing the manufacturing efficiency of the die casting product. The die casting machine comprises the following components: a cylindrical sleeve (10) which is provided an ejection opening (11) communicatedwith the casting inlet of a die cavity (7) at one end and is provided an insertion opening (12) being inserted with metal wire (W) with a preset length; a heating part (20) which is provided at the outside of the sleeve and is provided with a high-frequency coil for melting the metal wire that is inserted into the sleeve for a preset length at a derivation position (Y) of the movable die (3) relatively to the fixed die (2); and an ejection part (30) which is provided with a piston (31) which can be inserted from the insertion opening of the sleeve and cause the molten metal in the sleeve to eject from the ejection opening at a forming position (X) of the movable die relatively to the fixed die.
