Abstract
The invention provides a device for supporting a mold insert in space inside a mold cavity. A pilot and keeper assembly rests on the top of a mold part and extends into a mold cavity and through a small hole in the mold insert. Movement of a handle, which is part of the pilot and keeper assembly of the mold part, is transmitted through a shaft to a retaining means, which engages the opposite extremity of the hole to retain the insert in position during molding operations. After plastic is inserted into the base of the mold cavity and a sufficient curing time has transpired, the handle is rotated back to its initial position, thereby returning the retaining means to a nonretention position, and the pilot and keeper assembly is withdrawn from the mold.
