A device and a method for transferring inserts into a mold which has at least one insert receiving cavity. Included in the device are an insert positioner and an insert actuator. The insert positioner includes a transfer plate, which has a mold face with at least one insert transfer channel aperture which opens into an insert transfer cavity. Included in the insert actuator are an actuator plate, and a plate actuator. The actuator plate has at least one actuator pin extending therefrom. The actuator plate and the transfer plate are connected to so that each of the actuator pins is substantially axially aligned with the central axis of an insert transfer channel. For moving the inserts into the mold the plate actuator is adapted to move the acutator plate toward the transfer plate and thereby convey each actuator pin at least partially through each corresponding insert transfer channel. The device is adapted for operation by hand.

Insert transfer device and method

A pillow block for mounting a bearing having an outer spherical surface, the pillow block including a molded one-piece rigid foam body member with a bearing seat in which the spherical surface of the bearing can be supported. Mold apparatus is disclosed for molding the pillow block in modified forms in each of which the bearing seat has a construction preventing axial displacement of the bearing when mounted in the pillow block.
