Patent ID: 7775258

Claim:
A casted-part removing apparatus for use in a die casting machine, which includes a fixed die plate, a movable die plate, a mold having a fixed mold attached to the fixed die plate and a movable mold attached to the movable die plate, and an electric clamping machine having a mechanism driven by a servomotor and configured to move the movable die plate, the casted-part removing apparatus comprising: a removing device including a chuck configured to take hold of a casted part attached to the movable mold when the mold is opened after a casting operation, and a chuck driving mechanism configured to move the chuck from a fixed standby position in a space outside the mold to an expected position at which the chuck takes hold of the casted part between the fixed mold and the movable mold, the expected position being the same position for any given mold from a plurality of molds used with the casted-part removing apparatus and each mold from the plurality of molds being configured to produce a casted part different from a casted part produced by another mold from the plurality of molds; a driving device configured to drive pushing pins that push out the casted part from the movable mold; a control device constructed and arranged to set a distance between a portion of the casted part to be taken hold of by the chuck and the movable die plate, and to calculate a target position of the movable die plate based on the set distance so that the position of the portion of the casted part to be taken hold of by the chuck coincides with the expected position; and a servo-control device constructed and arranged to control the servomotor to stop the movable die plate during a mold opening operation at the target position so that the portion of the casted part to be taken hold of by the chuck reaches the expected position from which the casted part is to be removed.
