ABSTRACT:
An inverted U-shaped frame is provided to straddle the injection molding machine, and a chain conveyor provided with spaced apart groups of L-shaped insert carriers is moved along the frame. An insert chute is provided for working side of the frame for loading cylindrical inserts on the carriers. An insert transfer device is provided on the other side of the frame for transferring the inserts from the chain conveyor to an insert holder which is swung between the insert transfer device and the metal mold. The holder holds the inserts in a pattern corresponding to the pattern of the inserts when they are disposed in the metal mold. The chain conveyor is moved intermittently at a predetermined feed pitch. An insert detector is provided near the chute and when the detector detects that an insert carrier is not loaded with an insert, the direction of movement is reversed to return the empty insert carrier to the chute to load an insert thereon.
