Embodiment 1
[0030]Embodiment 1 of the molding die of the SC optical fiber adapter mounting sleeve of the present invention: includes an outer molding die and a blocking protrusion molding assembly. The blocking protrusion forming assembly includes a first core unit 91 and a second core unit 92, the first core unit 91 and the second core unit 92 have the same structure and are pulled back and forth in use for demoulding, A main molding cavity for molding the cylindrical body and the cantilever of the integrated installation sleeve is enclosed between the outer molding die and the first and second core monomers. The end of the first and second core monomers close to each other is the insertion end. Taking the first core monomer as an example, it mainly includes a hollow rod body part and an insertion end arranged at the front end of the hollow rod body part. The insertion end is It is formed by setting circumferentially spaced and axially extending insertion grooves on the hollow rod body, ...

The invention provides a forming mould for an SC optical fiber adapter mounting sleeve and a retaining protrusion forming assembly thereof. The retaining protrusion forming assembly comprises a first single mould core and a second single mould core, wherein the first single mould core and the second single mould core can be pulled oppositely front and back to achieve demoulding. An external forming mould body, the first single mould core and the second single mould core define a main forming cavity used for forming a mounting sleeve body and suspension arms. The ends, close to each other, of the first single mould core and the second single mould core are plug connection ends. The plug connection ends of the first single mould core and the second single mould core are provided with plug connection grooves and plug connection arms in a one-to-one correspondence mode, and the plug connection grooves and the plug connection arms can be oppositely connected in a plugged mode in the axial direction. The plug connection grooves and the plug connection arms define retaining protrusion forming cavities which communicate with the main forming cavity and are used for forming front retaining protrusions and rear retaining protrusions on the mounting sleeve. According to the forming mould provided by the invention, the integral mounting sleeve can be injection-molded integrally, the production efficiency is greatly improved, the manufactured integral mounting sleeve can be used for accurately positioning a ceramic sleeve, and the signal transmission quality of the SC optical fiber adapter is greatly improved.
Description
technical field [0001] The invention relates to an SC optical fiber adapter mounting sleeve molding die and a blocking protrusion molding assembly thereof. Background technique [0002] The fiber optic adapter is the centering connection part of the optical fiber active connector. The optical fiber adapter is a detachable and active connection device between the optical fiber and the optical fiber. It is mainly used to precisely connect the two end faces of the optical fiber to ensure the output of the optical fiber. The optical signal is coupled into the receiving fiber to a maximum extent. Therefore, to a certain extent, whether the performance of the optical fiber adapter is good or not has a great influence on the performance of the optical transmission system. [0003] There are many types of fiber optic adapters, such as SC, FC and so on. Among them, the SC fiber optic adapter is widely used due to its low price, convenient plugging operation, small insertion loss fl...
