Abstract

A method for removing a casted part, for use in a die casting machine comprises the steps of setting a position in which a chuck performs an operation to grasp a casted part attached to a movable mold as a position from which the casted part is to be removed, and setting a relative positional relationship between a handle portion which is a part of the casted part attached to the movable mold to be grasped by the chuck and a movable die plate. The method further comprises the step of advancing the chuck between the movable mold and the fixed mold and positioning the chuck at the position from which the casted part is to be removed, in parallel with the movement of the movable die plate. Additionally, the method comprises the steps of stopping the movable die plate when the handle portion of the casted part attached to the movable mold reaches the position from which the casted part is to be removed, grasping the handle portion of the casted part by using the chuck, and removing the casted part from the movable mold.

Dependent claims

A method for removing a casted part, for use in a die casting machine which includes a fixed die plate, a movable die plate, a mold composed of a fixed mold attached to the fixed die plate and a movable mold attached to the movable die plate, an electric clamping machine configured such that a mold opening/closing mechanism adapted to move the movable die plate is driven by a servomotor, and a casted part removing means including a chuck adapted to grasp a casted part attached to the movable mold after the mold opening operation and a chuck driving mechanism adapted to move the chuck from a waiting position at the exterior of the mold to any desired position between the fixed mold and the movable mold, the method comprising the steps of:

installing the casted part removing means at the fixed die plate;
setting a position in which the chuck performs an operation to grasp the casted part attached to the movable mold as a expected position from which the casted part is to be removed;
setting a relative positional relationship between a handle portion which is a part of the casted part attached to the movable mold to be grasped by the chuck and a movable die plate;
advancing the chuck between the movable mold and the fixed mold, and positioning the chuck at the expected position from which the casted part is to be removed, in parallel with the movement of the movable die plate;
stopping the movable die plate when the handle portion of the casted part attached to the movable mold reaches the expected position from which the casted part is to be removed, in the middle of the driving stroke of the movable die plate;
grasping the handle portion of the casted part by using the chuck, and removing the casted part from the movable mold;
and
moving the movable die plate in the mold opening direction, and having the chuck grasping the casted part wait at the waiting position, in parallel with the step of moving the movable die plate.

A casted part-removing apparatus for use in a die casting machine, which includes a fixed die plate, a movable die plate, a mold composed of a fixed mold attached to the fixed die plate and a movable mold attached to the movable die plate, and an electric clamping machine configured such that a mold opening/closing mechanism adapted to move the movable die plate is driven by a servomotor, the casted part-removing apparatus comprising:

a casted part removing means including a chuck adapted to grasp a casted part attached to the movable mold which has been opened after a casting operation, and a chuck driving mechanism adapted to move the chuck from a waiting position at the exterior of the mold to any desired position between the fixed mold and the movable mold;
a pushing/driving means adapted to drive pushing pins for pushing out a casted part attached to the movable mold;
a means for setting a position in which the chuck performs the operation for grasping the casted part attached to the movable mold as a expected position from which a casted part to be removed as well as for setting a relative positional relationship between a handle portion which is a part of the casted part attached to the movable mold to be grasped by the chuck and a movable die plate;
and
a servo-control means for stopping the movable die plate when the handle portion of the casted part attached to the movable mold reaches the expected position from which the casted part is to be removed, in the middle of the driving stroke of the movable die plate.
