ABSTRACT:
A part, such as finial or the like, is molded of plastic material so that during the molding process there is formed within the part a bore having internal threads formed therein for a predetermined extent of its length and so as to terminate a predetermined distance in from the entry end into the bore from the base of the part. A circular recess, surrounding the entry end of the bore, and a number of rectangular indentations, are also formed in the base during the molding of the part; which is molded with the parting line of the molded parts in a plane that includes the axis line of the bore and the internal threads.
The molding machine parts are formed to insure uniform and precise threads by locating the cavities, within which the parts are molded, all equally distant from the gate; and by forming cooling water tracks in predetermined positions with respect to the mold parts and cavities. A motor and suitable gearing are provided to rotate the externally threaded mold cores in the proper direction to separate the externally threaded mold cores from the internally threaded molded parts.
