Abstract
A tool for holding threaded inserts in a rotational mold includes a stud which projects within the mold cavity and which has a diameter substantially equal to the minor diameter of the threads of the insert. A spring loaded detent on the stud is received by the internal threads of the insert for holding the insert firmly against the inner wall of the mold yet permitting simple removal of the molded part. A retractor mechanism for using the tool with threaded inserts placed across the axis of removal of the molded part, is also taught.
Claims5
A molding tool for use in a mold having a wall defining an internal molding cavity, the tool being configured to hold an insert having a threaded internal bore within the mold cavity, the improvement comprising:
- a stud extending into the mold cavity from the housing wall;
- a detent transversely and retractably protruding from the stud;
- and
- means biasing the detent in the transverse direction away from a longitudinal axis of the stud whereby the stud, housing wall, detent and means are juxtaposed and configured so that the internal threads of the threaded insert are releasably retained by the detent when the bore of the threaded insert is placed over the stud.
