A plastic injection mold assembly is disclosed in which an electric servo motor very precisely controls rotational speeds and amounts of torque applied to cores which extend into the mold cavities as the cores are withdrawn from plastic components being molded and simultaneously directs the linear distances which the cores travel during such withdrawal. A method of accomplishing the molding of plastic components in this manner is also disclosed.

Plastic injection mold assembly and method of molding threaded plastic parts

A retainer for holding a plurality of waterfowl decoys has at least three arms pivotally mounted on a pin so as to be moveable between a first position in which the arms are aligned parallel to each other for storage and a open position in which the arms are angularly oriented with respect to one another. The device includes a locking pin for fitting into a first set of holes in the three arms for locking the arms in the first position and fitting into a second set of holes in the arms for locking the arms in the second position. The device further includes a moveable post at the end of each arm for retaining a waterfowl decoy and a ratchet engagement between the post and the arm to permit manual movement of the post with respect to the arm to its desired orientation to retain the post in the desired orientation after it has been positioned without requiring the tightening or untightening of screws and the like.
