Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable glue injection mold and a process. Background Art

[0002] In the traditional wire and cable glue injection process, bakelite molds are generally used, which have poor versatility and cause great waste of materials. The operation process requires multiple people to complete, which is inconvenient to operate and has extremely low production efficiency, that is, it is so-called time-consuming, labor-intensive and material-consuming. Summary of the Invention

[0003] The present invention aims to provide a cable glue injection mold and process, which have strong versatility, convenient operation, high production efficiency and glue material utilization rate, safe production operation and good glue injection effect.

[0004] Specifically, the present invention is achieved by adopting the following technical solutions:

The cable glue injection mold is provided with a glue injection hole connected to the interior. The interior of the cable glue injection mold includes a cone section, an inner mold section and a fixed section. The cable shaping mold is placed in the inner mold section and is offset from the fixed section.

[0006] Furthermore, the cone section occupies 3 / 4 of the overall length of the cable injection mold.

[0007] Furthermore, the length of the inner mold section is not greater than the length of the cabling shaping mold.

[0008] Furthermore, the inner diameter of the fixing section is smaller than the outer diameter of the cabling shaping mold.

[0009] Furthermore, the length of the fixing section is at least 5 mm.

[0010] Furthermore, the glue injection hole is located in the middle of the cone section.

[0011] Furthermore, the cable glue injection mold includes several separable parts, so that the cable glue injection mold can be opened.

[0012] Furthermore, the plurality of parts include a convex portion along the axis of the cable injection mold and a concave portion matching the convex portion.

[0013] In another aspect, a cable glue injection process is provided, comprising:

[0014] (1) Install the cable glue injection mold in a wire and cable stranding machine or a cable bundling machine;

[0015] (2) Install the multi-strand insulated wire core or tinned copper wire conductor to be produced and processed on the wire pay-off rack;

[0016] (3) Place the cable forming mold into the cable glue injection mold;

[0017] (4) The pitch and production speed are set so that the glue flows slowly and continuously from the injection hole to the dispersed wire cores or conductors, which then rotate and move forward to form a twisted cable.

[0018] The beneficial effects of the present invention are as follows: the cable glue injection mold and process of the present invention have strong versatility, save material and labor costs, increase production efficiency exponentially, and greatly reduce material consumption; the quality reliability of the processed and produced cables is higher, the amount of injected glue meets product requirements, and the product qualification rate is greatly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 1 4 is a cross-sectional view of a mold according to an embodiment of the present invention along the axis.

[0020] Figure 2 It is a right side view of the mold according to the embodiment of the present invention.

[0021] The numbers in the figure are: 1-step, 2-upper half, 3-lower half, 4-cone section, 5-inner mold section, 6-fixed section, 7-glue injection hole, 8-end. DETAILED DESCRIPTION

[0022] The present invention will be described in further detail below with reference to the embodiments and accompanying drawings.

[0023] Example:

[0024] One embodiment of the present invention is a cable glue injection mold. Figure 1 and Figure 2 .

[0025] The cable injection mold is made of metal, especially stainless steel, which has high strength, durable material and easy to clean glue.

[0026] like Figure 1 and Figure 2 As shown, the outer dimensions of the cable injection mold match the mold base of the cable processing equipment. Preferably, a step 1 is provided on the outside of the cable injection mold. The cable injection mold is divided into two parts, upper and lower, to facilitate segmenting the cable or replacing cables of different specifications, making operation more convenient. The cross-section of the upper half 2 is convex, and the cross-section of the lower half 3 is concave. When combined together, this effectively avoids the displacement of the cable injection mold and eliminates the quality risks caused by the displacement of the cable injection mold. It is understood that the cable injection mold can also be configured to include several separable parts, including a convex part along the axis of the cable injection mold and a matching concave part.

[0027] The cable glue injection mold's internal structure consists of three sections: a conical section 4, an inner mold section 5, and a fixed section 6. The conical section 4 occupies approximately three-quarters of the mold's overall length. This provides space for the injected glue to temporarily settle and evenly gather the cable cores to be processed. The injected glue then bonds the gathered, twisted cores together, leaving no gaps between them. A glue injection hole 7 is located in the center of the conical section 4, providing ample space for the glue to fully adhere to the cores. If the hole is too close to the end 8, glue backflow will occur, resulting in waste. If the hole is too close to the inner mold section 5, insufficient space will allow for glue injection, preventing the desired glue injection requirements. Therefore, the placement of the glue injection hole 7 in the center of the conical section 4 addresses the issues of high cost, waste, and low efficiency in twisted cable production. The cross-section of the glue injection hole 7 can be circular, square, or other shapes. The cabling and finalizing mold is placed within the inner mold section 5, offset from the fixed section 6. Cabling shaping molds of different apertures can be selected according to the structural dimensions of the cable product. That is, the cable glue injection mold of the present invention has strong versatility, and there is no need to replace the glue injection mold due to different cable product specifications. The length of the inner mold section 5 is designed according to the length of the cabling shaping mold and is adapted thereto, but the length of the inner mold section 5 is not greater than the length of the cabling shaping mold, for example, about 20 mm. The fixed section 6 is cylindrical and tubular and is used to fix the cabling shaping mold to prevent the cabling shaping mold from slipping out and causing glue leakage. The inner diameter of the fixed section 6 matches the outer diameter of the cabling shaping mold. Preferably, the length of the fixed section 6 is 5 mm to ensure that when it is impacted by the cabling shaping mold, it will not be deformed and cause the cabling shaping mold to slip out.

[0028] The process of implementing the glue injection process using the cable glue injection mold of the present invention is as follows:

[0029] (5) The cable glue injection mold of the present invention is installed in a wire and cable stranding machine or a wire bundling machine.

[0030] (6) Install the multi-strand insulated wire core or tinned copper wire conductor to be produced and processed on the wire pay-off rack.

[0031] (7) Select a suitable cable forming mold and place it into the cable injection mold.

[0032] (8) The corresponding pitch and production speed are set so that the glue flows slowly and continuously from the glue injection hole 7 to the dispersed wire cores or conductors, which are then rotated and pulled forward to be twisted into a twisted cable.

[0033] (9) Use cable water-blocking tape to wrap the outside of the twisted cable to prevent the glue from spilling.

[0034] The cable glue injection mold and process of the present invention have strong versatility, greatly improve the operation convenience and production efficiency, and greatly improve the utilization rate of glue materials; the production operation is safer and has excellent glue injection sealing effect.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, these embodiments are not intended to limit the present invention. Any equivalent changes or modifications made without departing from the spirit and scope of the present invention are also within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the content defined in the claims of this application.
