Apparatus for the manufacture of composite articles using rotating molds |
摘要 |
A molding apparatus for making a plastics pipe fitting or pipe coupling by injection-molding the plastics pipe fitting or coupling body, injection-molding at least one sealing ring separately but substantially simultaneously, and bringing the body and sealing ring together directly after the molding while these components are still in a hot as-molded state, so that a direct thermal bond is formed between them comprises respective injection-molding cavities for the body and sealing ring, and a reversible support for carrying the sealing ring out of its mold and into contact with the molded body. The respective molds are opened and the components are not stripped but are brought together for bonding while still in position on respective mold members, thereby eliminating intermediate handling and ensuring that the molded components remain clean and of accurate shape and dimension as they are brought together.
