摘要： A method and apparatus are described. A thermosetting molding material, suitably a synthetic resin composition such as a phenolic molding composition, is initially heated and plasticized. The plasticized mass is passed as a stream through an injection nozzle which is maintained at a temperature sufficiently high to keep the mass in a plasticized condition but sufficiently low to avoid any substantial curing or setting-up of the mass. The plasticized mass is next passed through a temperature-controlled manifold maintained at a temperature sufficiently high to keep the mass in a plasticized condition but sufficiently low to avoid any substantial curing or setting-up of the mass. In the manifold the plasticized stream is divided into two or more smaller streams which are passed through a plurality of outlets into a plurality of partially open, heated molds. The mold cavities are maintained at temperatures sufficiently high to cure the thermosetting molding material. When the partially open molds are full, the feed stream is interrupted, and the molds are then completely closed to press and cure the plasticized material enclosed within them. The cured, finished article is removed from the mold and the process repeated.The apparatus of the present invention includes a stationary assembly and a movable assembly. The stationary assembly is comprised of a support plate which has a heat plate mounted thereon, a temperature-controlled manifold mounted on the heat plate and a plurality of mold faces positioned on the heat plate surrounding the periphery of the manifold. The movable assembly is comprised of a support plate which has a heat plate mounted thereon and a plurality of mold faces, corresponding to, and adapted to be aligned with the mold faces on the stationary assembly. Means are provided to move the movable assembly into close proximity with the stationary assembly to form partially open mold cavities. Means are provided to feed a supply of thermosetting molding material through the manifold into the partially open mold cavities. Means are also provided to completely close the mold cavities and for subsequent retracting the movable assembly to allow access to the mold face areas.

The plasticized mass is passed as a stream through an injection nozzle which is maintained at a temperature sufficiently high to keep the mass in a plasticized condition but sufficiently low to avoid any substantial curing or setting-up of the mass. The plasticized mass is next passed through a temperature-controlled zone maintained at a temperature sufficiently high to keep the mass in a plasticized condition but sufficiently low to avoid any substantial curing or setting-up of the mass. The plasticized stream is passed into a partially open, heated mold. The mold cavity is maintained at temperatures sufficiently high to cure the thermosetting molding material. When the partially open mold is partially full, the feed steam is interrupted, and the mold is then completely closed to press and cure the enclosed plasticized material. The cured, finished article is removed from the mold and the process repeated.An apparatus for conducting the process of the invention includes a stationary assembly and a movable assembly. The stationary assembly is comprised of a stationary platen which has a heat plate, a temperature-controlled sprue bushing and a mold face positioned thereon. The movable assembly is comprised of a movable platen which has a heat place mounted thereon and a mold face, corresponding to, and adapted to be aligned with, the mold face on the stationary assembly to form a partially open mold cavity. Means are provided to feed a supply of thermosetting molding material through the sprue bushing into the partially open mold cavity. Means are provided to completely close the mold cavity and place the apparatus in a compression stage. Means are also provided for the subsequent retraction of the movable assembly to allow removal of a molded article and access to the mold area.

摘要： An improved nozzle feed assembly is described. The assembly includes temperature-controlled member, preferably cylindrical in shape, having a closed end and an open end. The open end is fitted with standard threads to facilitate attachment of the nozzle member to the feed barrel of a conventional screw-type molding machine. The nozzle member has an internal temperature controlling means and a plurality of feed outlets positioned on the periphery of the nozzle member near the closed end. The temperature maintained in the nozzle member is sufficiently high to maintain the thermosetting molding material within the nozzle member in a plasticized state and sufficiently low that no substantial curing of the thermosetting molding material takes place. In an alternate mode, the assembly includes a sleeve member positioned around the periphery of the nozzle member and moveable to cover and uncover the feed outlets in the periphery of the nozzle member. In such alternate mode, means are provided to move the sleeve member from a position wherein the feed outlets are covered when the mold faces are open to a position wherein the feed outlets are uncovered when the mold faces are closed.
