    摘要： A first molding core is positioned within a first portion of a separable mold having a nonlinear chamber. A second molding core having an end matable with the end of the first core is inserted within a second end portion of the chamber of the mold adjacent and in slidable contact with a third molding core. The first molding core is retractable from the mold and the second and third molding cores are pivotally connected to one of the mold sections for removing the molded article and the second and third molding cores from the mold section. The third molding core is slidable along the second molding core for releasing the article from the second and third molding cores.

    摘要： A generally hollow article is produced by coating a collapsible, seamless bladder with integrable particles, integrating the particles into a unitary structure, and thereafter removing the bladder therefrom. The apparatus includes coating means to form a fluidizing mass the particles, means for acting upon the bladder to promote adhesion, and means for integrating the particles on the bladder into a hollow article. The bladder is normally nonadherent to the particles, and is comprised of at least one material that is responsive to the adhesion promoting means.

    摘要： Apparatus for molding plastic articles having an undercut, rib, thread, or the like deformation comprises a core divided longitudinally into sections having molding ends that are radially shiftable to and from an expanded article-molding position and a contracted article-release position. A center pin holds the sections expanded. The core may be shifted axially resulting in the center pin being withdrawn from support of the molding ends of the sections. This causes a cam ring that encircles the sections to urge the sections radially inwardly by the engagement of cam-follower lugs on the sections to collapse positively the sections without interference from the pin.

    摘要： IN A METHOD FOR PRESSURE MOLDING PLASTIC MATERIALS, A STRIP OF DEFORMABLE PLASTIC IS EXTRUDED OVER A MOLD CAVITY. A PREDETERMINED PIECE OF THE EXTRUDATE IS CUT FROM THE STRIP AND FORMED IN THE MOLD UNDER PRESSURE BY MEANS OF A COLLAPSIBLE CORE AND BUSHING ASSEMBLY WHICH FORMS THE PLASTIC AT RELATIVELY LOW PRESSURE IN CONJUNCTION WITH THE FORMING SURFACE OF A MOLD CAVITY.

    THE COLLAPSIBLE CORE ASSEMBLY INCLUDES A SLIDABLY MOVABLE ACTUATOR AND MATING THREAD-FORMING PORTIONS WHICH ENGAGE SUCH ACTUATOR WHEREBY ADJACENT END PORTIONS OF SAID FORMING PORTIONS ARE FORCED APART AT FIRST END PORTIONS, AND APPROACH EACH OTHER AND ARE READILY RELEASED FROM A MOLDED PIECE AT OPPOSED SECOND END PORTIONS.

    摘要： AN APPARATUS FOR FORMING A SOCKET ON THE END OF A PLASTIC PIPE COMPRISING A MOLD FORMED BY A HOLLOW OUTER MEMBER AND A CORE POSITIONED WITHIN AND SPACED FROM THE OUTER MEMBER. THE OUTER MEMBER IS FORMED BY TWO SEPARATE SECTIONS MOVABLE RADIALLY WITH RELATIVE TO ONE ANOTHER. THE CORE IS COMPRISED OF TWO PAIRS OF SEPARATE SEGMENTS. ONE PAIR OF THE SEGMENTS IS RETRACTABLE AXIALLY INTO A HOLLOW TUBULAR MANDREL. SITUATED WITHIN THE MANDREL IS AN AXIALLY MOVABLE NOSE KEY FOR POSITIONING THE SEGMENTS IN THE CORE. A HOLDING MEMBER FEEDS THE PIPE UNDER PRESSURE INTO THE SPACE IN THE MOLD BETWEEN THE CORE AND THE OUTER MEMBER FOR FORMING THE SOCKET AND

    AT THE SAME TIME INCREASING THE PIPE WALL THICKNESS OF SOCKET.
