20230059383 · 2023-02-23 ·

The present invention relates to an FPC connector housing, more particular to a DDRS connector housing. The invention also relates to a method for producing the connector housing as well as to a cavity mold suitable for the production of the connector housing. The cavity mold comprises a double gating system with centrally positioned injection gates. The connector housing can be used in a connector for mounting on a flexible printed circuit (FPC) assembled in various kinds of electrical and/or electronic devices.

Injection Mold Capable of Planing and Cutting Gates in Inside Thereof and Planing and Cutting Method

An injection mold capable of planing and cutting gates in an inside thereof and a planing and cutting method are provided. The injection mold includes a blade fixed block arranged between a moving mold and a fixed mold. Blades arranged on the blade fixed block and configured for cutting off gate condensed-material. The mold includes ejectors for ejecting out the gate condensed material and the blade fixed block. Runners formed between the blade fixed block and the fixed mold. Cut holes for communicating runners and gates are formed in blades. Ejector holes for penetrating the ejectors are formed in portions of the blade fixed block which correspond to bottoms of runners. The blade fixed block moves relative to the moving mold in a mold opening direction. The moving mold is provided with a limiting mechanism for limiting the blade fixed block after injection molding parts are separated from a cavity.

Contact Lens Packaging

Packages, systems, and methods of the present disclosure are generally directed to the use of side gating in injection molding to form packaging for contact lenses. As compared to gating along a top surface of a contact lens package, the use of a side gate in injection molding to form a package for contact lenses may significantly reduce the time required to cool plastic in the injection mold, thus offering potential to reduce the overall cycle time for the injection molding process and increase fabrication throughput of the package.

Method for producing plastic plug-in connector

A plug-in connector produced by injection molding a plastic material and having an internal channel for a fluid and having three main sections situated axially one behind the other. The plug-in connector has a gate point on its outer circumference solely on one side and a mass distribution of the plastic material that is radially asymmetrical with respect to the circumference and which is present in at least one of the main sections of the shaped part. A method for the production of the plug-in connector is likewise disclosed.

Resin molded product and method for producing resin molded product

A resin molded product (10) includes a resin molded product main body (11), and a protrusion (12) integrally formed with the resin molded product main body (11) and protruding from the resin molded product main body (11). At injection molding of the resin molded product (10), molten resin flows through a portion (C-1) corresponding to the protrusion (12) in a cavity (C) defined by a pair of molds (20, 30). A concave portion (14) is formed on a rear side of the protrusion (12), and a bulging portion (12a) having a hollow bag shape is formed on a front side of the protrusion (12).

Side-gate injection molding apparatus and side-gate nozzle assembly

A side-gate injection molding apparatus and a side-gate nozzle assembly are disclosed. The side-gate nozzle assembly delivers moldable material to a cavity insert that is beside the side-gate nozzle assembly. The side-gate nozzle assembly includes a nozzle body having a nozzle flow channel and a widthwise slot extending across a downstream side of the nozzle body. The nozzle flow channel has an outlet that ends at a wall of the slot. A load component is received in the slot and has a load component flow channel in fluid communication between the nozzle body outlet and an outlet at an end of the load component. A side-gate tip assembly is adjacent to the end of the load component and is in fluid communication between the load component flow channel and the cavity insert. In operation, thermal expansion of the load component presses the side-gate tip assembly towards the cavity insert.
