Description

Technical Field

[0001] This utility model relates to the field of connector housing molding technology, and in particular to a connector housing molding die structure. Background Technology

[0002] In the manufacturing of connector housings, injection molding is commonly used to improve the protective performance and structural stability of connectors. Specifically, the existing process involves connecting the connector cable and the core of the connector portion to a terminal block. Then, the area to be coated and the stripped end of the cable core are placed together in a mold. Plastic is then injected into the mold using injection molding equipment, forming the protective outer shell. Since the connector cable itself does not require coating, it remains exposed outside the mold.

[0003] However, this process has significant drawbacks in actual injection molding. Because the entire operation relies on manual placement of cables and connectors into the mold, and given the lengthy injection molding process, human error can easily cause strain on the exposed cables outside the mold. Excessive strain on the cables can lead to breakage of the internal cores due to their small diameter and low tensile strength, directly causing the connector to lose its electrical connection and resulting in product failure. This not only reduces production efficiency but also increases production costs. Therefore, there is an urgent need to improve existing connector housing injection molding dies to address the cable damage problem caused by manual operation. Utility Model Content

[0004] The purpose of this utility model is to provide a connector housing molding die structure to address the defects and shortcomings of the existing technology.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The connector housing forming mold structure of this utility model includes a moving mold plate and a fixed mold plate; the moving mold plate is provided with an upper mold; the fixed mold plate is provided with a lower mold; the fixed mold plate is provided with at least one spring clip for clamping and fixing the cable; the moving mold plate is provided with a clamping member for clamping the spring clip; the number of clamping members is equal to the number of spring clips.

[0007] Furthermore, the clip is an elastic U-shaped component; both inner sidewalls of the elastic U-shaped component are provided with concave arc shapes.

[0008] Furthermore, a rubber pad is fixed to the surface of the concave shape;

[0009] Furthermore, both ends of the elastic U-shaped member are provided with rounded corner surfaces; the clamping member is composed of two clamping strips; and a chamfered surface is provided between the bottom surface and the side surface of the clamping strip.

[0010] Furthermore, all the pressure strips are fixed to the connecting rods; the connecting rods are locked to the moving template by bolts.

[0011] Furthermore, both ends of the elastic U-shaped component are provided with extension sections; the extension sections are bent into arc strips; the outer wall of the arc strips is a rounded corner surface; the elastic U-shaped component, the arc strips, and the concave shape are integrally formed.

[0012] With the above structure, the beneficial effects of this utility model are as follows: after the clamping member leaves the spring clip member, the spring clip member opens freely, and the cable can be easily inserted into the inside of the spring clip member; before the upper mold and lower mold are closed, the end that needs to be coated is placed into the cavity of the lower mold, and then the end of the cable is inserted into the spring clip member; after the moving mold plate moves closer to the fixed mold plate and the upper mold and lower mold are closed, the clamping member clamps and fixes the spring clip member, reducing the pulling force on the connecting plate caused by the cable being pulled down externally, ensuring that the risk of the wire core being pulled off the connecting plate is reduced during the injection molding process, reducing the risk of product failure, and improving the yield rate.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 4As shown, the connector housing molding die structure of this utility model includes a moving mold plate 1 and a fixed mold plate 4; the moving mold plate 1 is provided with an upper mold; the fixed mold plate 4 is provided with a lower mold 6; the fixed mold plate 4 is provided with at least one spring clip 5 for clamping and fixing the cable; the moving mold plate 1 is provided with a clamping clamp for clamping the spring clip 5; the number of clamping clamps is equal to the number of spring clips 5.

[0022] After the clamping component leaves the spring clip 5, the spring clip 5 opens freely, and the cable can be easily inserted into the inside of the spring clip 5. Before the upper mold and lower mold 6 are closed, the end that needs to be coated is placed into the cavity of the lower mold 6, and then the end of the cable is inserted into the spring clip 5. After the moving mold plate 1 moves closer to the fixed mold plate 4 and the upper mold and lower mold 6 are closed, the clamping component clamps and fixes the spring clip 5, reducing the pulling force on the connecting plate caused by the cable being pulled down externally. This ensures that during the injection molding process, the risk of the wire core being pulled off the connecting plate is reduced, the risk of product failure is reduced, and the yield rate is improved.

[0023] In a preferred embodiment of this utility model, the spring clip 5 is an elastic U-shaped component; both inner sidewalls of the elastic U-shaped component are provided with arc-shaped concave shapes 502; the circular wire is clamped and fixed by the arc-shaped concave shapes 502 on both sides.

[0024] As a preferred embodiment of this utility model, a rubber pad 504 is fixed on the surface of the concave shape 502; the rubber pad 504 can not only generate greater friction between the cable surface and the concave shape 502 and play an anti-slip role, but also prevent the cable from being rigidly squeezed by the spring clip 5, thus better protecting the cable surface.

[0025] In a preferred embodiment of this utility model, both ends of the elastic U-shaped member are provided with rounded corner surfaces 503; the clamping member is composed of two pressure strips 2; a chamfered surface 201 is provided between the bottom surface and the side surface of the pressure strip 2; when the moving template 1 approaches the fixed template 4, the chamfered surfaces 201 of the two pressure strips 2 press against the rounded corner surfaces 503 on both sides respectively, so that the two arms of the elastic U-shaped member approach each other, and the concave shapes 502 on both sides clamp the cable.

[0026] In a preferred embodiment of this utility model, the pressure strips 2 are all fixed on the connecting rods 3; the connecting rods 3 are locked and fixed on the moving mold plate 1 by bolts; threaded holes are opened on the moving mold plate 1, and through holes are provided on the connecting rods 3. After the bolts pass through the through holes, they are threadedly connected to the threaded holes to fix the connecting rods 3 on the moving mold plate 1.

[0027] In a preferred embodiment of this utility model, both ends of the elastic U-shaped component are provided with extension sections; the extension sections are bent into arc strips; the outer wall of the arc strips is a rounded corner surface 503; the elastic U-shaped component, the arc strips, and the concave shape 502 are integrally formed; the elastic U-shaped component is made of spring steel material, and the entire spring clip 5 structure is formed by bending, which improves the forming efficiency of the spring clip 5; connecting sleeves 501 are provided on both sides of the spring clip 5, and threaded holes are provided on the fixed template 4. After the bolt passes through the connecting sleeve, it is threadedly connected to the threaded hole, thereby fixing the spring clip 5 to the fixed template 4.

[0028] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
