Description

Technical Field

[0001] This utility model relates to the field of insert fixture technology, and in particular to an FPC submerged injection molding die. Background Technology

[0002] FPC (Flexible Printed Circuit) is a type of printed circuit board made with a flexible substrate, characterized by high reliability, excellent flexibility, and thinness. In existing technologies, FPCs are connected to injection-molded products through direct assembly. This method leads to connector oxidation and loosening, resulting in poor contact, abnormal noises, and negatively impacting the user experience. Summary of the Invention

[0003] According to an embodiment of the present invention, an FPC submersible injection mold is provided, comprising: a mold assembly, an overmolding plate, an FPC plate, and an insert fixture; The mold assembly includes: an upper mold core and a lower mold core; The upper mold core is covered on the lower mold core, and an injection cavity is provided between the upper mold core and the lower mold core. A fixture groove is opened on the lower mold core, and the insert fixture is located in the fixture groove. An installation groove is opened in the insert fixture. The FPC board is inserted into the installation groove, and one end of the board extending out of the installation groove is connected to the rubber-coated board. The rubber-coated board is located in the injection cavity.

[0004] Furthermore, a sealing cap is connected to one end of the FPC board that extends out of the mounting groove. The sealing cap covers the opening of the mounting groove, and the rubber-coated board is connected to the sealing cap.

[0005] Furthermore, the mold assembly also includes: an upper mold plate and a lower mold plate; The upper mold core is located below the upper mold plate, and the upper mold plate has an injection port that connects to the injection cavity. The lower mold plate is located below the lower mold core.

[0006] According to an embodiment of the present invention, an FPC submersible overmolding injection mold is provided. An insert fixture is installed into the fixture groove, and the overmolding plate is connected to the FPC plate. By inserting the FPC plate into the insert fixture, the overmolding plate is fixed within the injection cavity, thus fixing the overmolding plate to the injection-molded product. This ensures the stability of the connection between the FPC plate and the injection-molded product, prevents the FPC plate from loosening, and improves the user experience.

[0007] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

Detailed Implementation

[0010] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0011] like Figures 1-8 As shown, an FPC submersible overmolding injection mold according to an embodiment of the present invention includes: a mold assembly, an overmolding plate 5, an FPC plate 6, and an insert fixture 7; The mold assembly includes: an upper mold core 1 and a lower mold core 2; The upper mold core 1 is covered on the lower mold core 2, and an injection cavity is provided between the upper mold core 1 and the lower mold core 2. A fixture groove is opened on the lower mold core 2, and the insert fixture 7 is located in the fixture groove. An installation groove is opened in the insert fixture 7. The FPC plate 6 is inserted into the installation groove, and one end of the plate extending out of the installation groove is connected to the rubber-coated plate 5. The rubber-coated plate 5 is located in the injection cavity.

[0012] This application installs the insert fixture 7 into the fixture slot, connects the overmolded sheet 5 and the FPC sheet 6, and fixes the overmolded sheet 5 in the injection cavity by inserting the FPC sheet 6 into the insert fixture 7. This fixes the overmolded sheet 5 in the injection molded product 8, thereby fixing the FPC sheet 6 on the injection molded product 8, ensuring the stability of the connection between the FPC sheet 6 and the injection molded product 8, preventing the FPC sheet 6 from becoming loose, and improving the user experience.

[0013] like Figures 5-6 As shown, one end of the FPC board 6 extending out of the mounting groove is connected to a sealing cap 51, which covers the opening of the mounting groove, and the rubber-coated board 5 is connected to the sealing cap 51.

[0014] In this embodiment, the sealing cap 51 is placed over the opening of the mounting groove to prevent the injection molding material from entering the insert fixture 7 during the injection molding process.

[0015] like Figures 1-6 As shown, the mold assembly further includes: an upper mold plate 3 and a lower mold plate 4; The upper mold core 1 is located below the upper template 3. The upper template 3 has an injection port that connects to the injection cavity. The lower template 4 is located below the lower mold core 2.

[0016] In this embodiment, the injection material is introduced through the injection port and then into the injection cavity to form the injection molded product 8.

[0017] Above, refer to Figures 1-8 This application describes an FPC submersible injection molding mold according to an embodiment of the present invention. An insert fixture 7 is installed into a fixture groove to connect the overmolding plate 5 to the FPC plate 6. By inserting the FPC plate 6 into the insert fixture 7, the overmolding plate 5 is fixed within the injection cavity, thus fixing the overmolding plate 5 into the injection-molded product 8. This ensures the stability of the connection between the FPC plate 6 and the injection-molded product 8, prevents the FPC plate 6 from loosening, and improves the user experience.
