Description

Technical Field

[0001] The present application relates to the field of clock spring connectors, and in particular to a clock spring connector and a mold thereof. Background Art

[0002] Clock spring is a component used in automobiles, also commonly called airbag spring or rotary connector. Its main function is to electrically connect the steering wheel and / or airbag wires to the control unit through the adjustable wire inside, so that the wires are not easily torn off when the steering wheel rotates.

[0003] Specifically, the clock spring in the prior art can refer to the patent application document with publication number CN 116454654 A and publication date 2023.07.18. This invention patent discloses a new clock spring, whose wire is installed on the port of the circuit board through a connector with a pin, and the wire is wound around the rotating part so that the wire rotates with the rotating part, so that the wire has a margin for retraction and extension when the steering wheel rotates.

[0004] In the existing related technology, the connector of the clock spring includes an injection molded insert and a conductive plate, and the conductive plate is fixedly embedded in the injection molded insert. Specifically, the injection molded insert includes an injection molded plug end and an injection molded connection end, and the injection molded plug end and the injection molded connection end are integrally injection molded. The conductive plate includes a conductive connection end and a conductive plug end, and the conductive connection end is integrally connected with the conductive plug end, and the conductive connection end is fixedly embedded in the injection molded connection end, and the conductive plug end is fixedly embedded in the injection molded plug end, and the conductive plug end is protrudingly arranged on the injection molded plug end to form a conductive pin.

[0005] Specifically, the connector in the prior art can refer to the patent application document with announcement number CN 212751223 U and announcement date 2021.03.19. The utility model discloses a connection structure for a clock spring, which simplifies the production cost of the clock spring connector by fixing a conductive plate member embedded in an integral injection molded injection insert.

[0006] When producing the connector of the clock spring, the conductive plate needs to be placed in the molding cavity of the mold first, and then liquid plastic is injected into the molding cavity. After the liquid plastic is cooled and formed, the conductive plate can be fixedly embedded in the injection molded insert.

[0007] With regard to the above-mentioned related technologies, liquid plastic will shrink and deform during cooling and molding, and it is not easy for operators to ensure that the conductive plate is accurately placed in the molding cavity. The above factors make it easy for the conductive plate to shift after the liquid plastic is molded, making it difficult for the connector to be aligned with the port on the circuit board during use, and the production accuracy of the connector is poor. Summary of the invention

[0008] In order to ensure the production accuracy of a clock spring connector, the present application provides a mold of a clock spring connector.

[0009] The mold of a clock spring connector provided in this application adopts the following technical solution:

[0012] By adopting the above technical solution, when injection molding the injection molded insert, the conductive pins of the conductive plate are first placed in the pin positioning grooves, so that the conductive plate is not easily offset due to installation errors of the operator or shrinkage deformation of the liquid plastic, thereby ensuring the production accuracy of the clock spring connector.

On the one hand, the conductive pin is not easy to shake in the pin positioning groove, and on the other hand, it is convenient for the operator to place the conductive pin in the pin positioning groove, thereby reducing the situation where the sliding molded part hinders the operator from placing the conductive pin.

[0019] Optionally, the molding cavities are provided with a plurality of molding cavities, and the plurality of molding cavities are connected via a connecting flow channel.

When the conductive pin 102 of the clock spring connector is placed in the pin positioning groove, the inner wall of the pin positioning groove is tightly matched with the conductive pin 102 of the clock spring connector.

The end of the ejector pin 72 away from the ejector plate 71 is located in the molding cavity, so that after the injection molded insert 1 of the clock spring connector is molded, the ejector plate 71 is driven by the injection molding machine to move, so that the ejector pin 72 ejects the injection molded insert 1 in the molding cavity out of the mold.

[0084] Reference Fig.13 and Fig.14 The movable mold core 6 is detachably mounted with a slider strip 61 by bolts, and a rear slider slot is formed between the slider strip 61 and the movable mold core 6. The slider slot is slidably matched with a molding slider 62, and the molding slider 62 is fixedly mounted with a slider molding part 622, and the slider molding part 622 is used to mold the injection molded insert 1 of the clock spring connector in the molding cavity. The molding slider 62 is provided with a molding bevel 621, and the corners of the molding bevel 621 are chamfered. The fixed mold core 4 is installed with a molding bevel block 41, and the molding bevel block 41 is plugged into the molding bevel 621. Combined Fig.21 The movable mold core 6 is provided with a mold core slide hole, which is connected to the fourth cavity 1004 and slides in the mold core slide hole to make full use of the space of the movable mold core 6 and drive the molding slider 62 to move toward the fourth cavity 1004 through the molding bevel block 41, thereby molding the injection molded insert 1 of the clock spring connector.

Then press the driving protrusion 83 again to allow the driving bevel block 31 to be inserted into the driving bevel groove, close the movable mold core 6 with the fixed mold core 4, and both the first row position 8 and the second row position 9 move toward the fixed mold core 4 to form a molding cavity, and finally inject liquid plastic into the molding cavity through the injection port to mold the clock spring connector.
