    摘要: Phenolic novolak resins are described which are structurally characterized as having from about 55% to about 90% of the available theoretical paraphenyl linkages in the resin chain bridged to a phenyl group. The resin compositions of this invention provide extended resin stability at relatively low temperatures without significant adverse affect on the cure speed at the molding temperature. The resins are especially suited for use in runnerless injection or cold manifold molding processes, but can also be used in transfer, compression and injection molding processes.

    摘要: A method of making a one piece insert (10) for retaining a plurality of electrical contacts (20) in an electrical connector. The insert (10) includes a plurality of bores or passageways (15) having integral with the insert means for retaining a contact within each of the insert passages. The integral means for retaining a contact (20) includes a plurality of radially deflectable contact retaining fingers (11) adjacent a plurality of ribs (16). Shoulders (17) on the ribs (16) and the free ends (12) of the retention fingers (11) engage forwardly and rearwardly facing shoulders (21, 22) on a contact, thereby captivating a portion (25) of the contact within the insert. The radially deflectable fingers (11) in the insert allow a contact to be inserted and removed from one end of an electrical connector. The method of making the insert includes two mold halves (70, 80) and a core pin (50) mounted to one mold half (70) and a mating core bushing (60) mounted to the other mold half (80) for each passage which is desired. The structure (54, 55) of the core pin (50) which mates with the structure (64, 65) of the core bushing define the shoulders (17), the ribs (16) and the deflectable fingers (11), which are formed in the molding process.

    摘要: A process for producing shaped parts from synthetic and similar workable materials by filling molds under pressure, hardening and removing the articles from the molds. Movable, essentially identical mold carriers are provided with article-related mold inserts preselected for the work cycle and locked in place in the carriers. The forming tool is filled with the synthetic, it is exposed for a given time to certain temperature and pressure conditions, the tool is opened and the inserts are expelled. The form carriers are then outfitted with another set of form inserts while the first set of mold inserts are removed from the molding cycle.

    摘要: A molding apparatus is provided having an interchangeable material feed cylinder selected either for injection molding or transfer molding. The selected material feed cylinder receives the molding material and discharges the same to the cavity mold supporting structure. Displacement means in the form of a dual piston cylinder having a selectively variable stroke is provided for feeding the molding material through the selected material feed cylinder. The apparatus further provides for control means for controlling the length of travel of the displacement means depending upon the material feed cylinder selected for use in the apparatus.

    摘要: A method for molding one piece seamless contoured structures. The mold consists of a hollow, cylindrical mold member whose internal surface area defines the external surface of the piece to be molded, that is adaptive to receive a piston having a reservoir containing a fluid plastic and a mandrel mold member of low melting alloy whose shape defines the internal surface of the molded structure. The piston is forced upward to cause the fluid plastic to flow into the interstices and allowed to cure. Heat is applied to the mold assembly to melt the alloy to allow removal of the contoured structure when the mold assembly is disassembled.
