Description

Technical Field

[0001] The present application relates to the technical field of cable manufacturing, and in particular to a double-branch mold. Background Art

[0002] Cables are widely used in modern industry. They are mainly used in power transmission, communication, control systems and other fields. The quality and performance of cables directly affect the normal operation of equipment and the stability of the system. In the cable production process, the use of molds is a key link to ensure the dimensional accuracy and molding quality of cables. Especially in the production of double-branch cables, double-branch molds are widely used because they can process multiple cables arranged in parallel.

[0003] In the prior art Figure 1 and Figure 2 The molding channel at the front end of the mold core 2 lacks a part to guide the material. The design of the double-branch mold usually focuses on controlling the flow path of the material to ensure uniform glue discharge. However, since unstable flow areas may be generated on the surface of the mold core, especially near the mold core nozzle, this often leads to uneven material flow rate, thereby affecting the quality of the final product. Some traditional molds do not have special structures designed to optimize the material flow in this part, resulting in defects such as corrugations and unevenness on the product surface, causing the produced double-branch cables to crack easily. When used separately, the cable sheath is easily torn or the residual material on both sides is uneven.

[0004] Therefore, we need a double-branch mold to solve the problem that the surface material of the produced cable is uneven and easy to crack, so that the surface material of the produced cable can be uniform and not easy to crack. Utility Model Content

[0005] The purpose of this application is to solve the problem that the surface material of the produced cable is uneven and easy to crack. In order to solve the above problem, this application provides a double-branch mold, which can make the surface material of the produced cable uniform and not easy to crack.

Each mold cavity is provided with an independent molding channel, and the front end of the mold cavity extends out of the front end of the mold core; a transition groove, the transition groove is opened between the front end of the mold core and the inner surfaces of the two mold cavities, and the shape of the transition groove is a smooth arc-shaped surface. The arc top of the transition groove is flush with the edge of the mold cavity, and the two ends of the transition groove are smoothly connected to the outer side of the mold core respectively, and the center line of the transition groove is arranged parallel to the center line of the mold core.

[0007] In the above technical solution, the embodiment of the present application optimizes the flow path of the material by setting a transition groove with an arc-shaped groove between the side walls of the mold cavity of the mold core, so that the material can flow through the mold core surface more smoothly, reduce turbulence, ensure the uniformity of the flow rate and pressure of the material, thereby improving the quality and consistency of the dual-to-cable, and solving the problem of uneven surface material of the produced cable causing easy cracking, so that the surface material of the produced cable can be uniform and not easy to crack.

[0008] Further, according to an embodiment of the present application, the width of the transition groove is set to 2 to 6 mm.

[0009] Further, according to an embodiment of the present application, the transition groove runs through the entire front end of the mold core along the axial direction of the mold core.

[0033] For the purposes of simplicity and illustration, the principles of the embodiments are described primarily with reference to examples. In the following description, many specific details are provided to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that the embodiments may not be limited to these specific details in practice. In some instances, well-known methods and apparatus are not described in detail to avoid unnecessarily obscuring the embodiments. In addition, all embodiments may be used in combination with each other.

[0034] Example 1: Figure 3-8 As shown, a double-branch mold includes:

[0035] The mold core 2 is used in conjunction with the mold body 1. The mold core 2 is located inside the mold body 1. The mold core 2 is designed as a cone as a whole, gradually narrowing from the tail end to the front end of the mold core 2. The cone setting helps the material flow smoothly during the molding process and reduces retention.

[0036] The front end of the mold core 2 extends out of the mold body 1 to form two parallel mold cavities 21. There are at least two mold cavities 21. Each mold cavity 21 is provided with an independent molding channel. The molding channel is cylindrical. The molding channels of the two mold cavities 21 have the same diameter to ensure that the material can be evenly molded through the mold cavity 21.

[0037] The mold cavity 21 is arranged at the front end of the mold core 2. Each mold cavity 21 exists independently and has a cylindrical molding channel inside. The front end of the mold cavity 21 extends 1 to 2 centimeters from the front end of the mold core 2 to ensure that the material has sufficient flow space when passing through the mold cavity 21, thereby improving the molding quality and stability of the material.

[0038] At the front end of the mold core 2, a transition groove 22 is provided between the inner surface of the mold cavity 21 and the outer side of the mold core 2. The transition groove 22 is in the shape of a smooth arc-shaped surface. The arc-shaped surface improves the smoothness of the material flow, reduces the turbulence generated by the material during the flow process, and avoids flow velocity fluctuations and material deposition problems.

[0039] The arc top of the transition groove 22 is flush with the edge of the mold cavity 21, and the two ends are smoothly connected to the outer side of the mold core 2 to avoid stagnation or sudden changes in the flow of materials.

[0040] The width of the transition groove 22 is set to 2 to 6 mm, and the depth is set to 1 to 3 mm. This size range ensures smooth flow of materials through the transition groove 22 and avoids pressure fluctuations caused by changes in the material flow path. Experiments on a double-branch cable made with this transition groove 22 configuration have specific experimental data as shown in Tables 1 and 2 below:

[0041] Table 1:

[0042]

[0043]

[0044] Table 2:

[0045]

[0046]

[0047] As mentioned above, increasing the depth of the transition groove 22 helps to improve the stability of the material flow. The deeper groove of the transition groove 22 can better guide the material, reduce turbulence, and make the material flow more smoothly in the mold core 2. Increasing the groove width also helps to improve the flow of the material, but its main function is to expand the flow channel and make the material flow rate more uniform. The wide groove can reduce the flow rate fluctuation caused by the narrow channel.

[0048] The transition groove 22 runs through the entire front end of the mold core 2 along the axial direction of the mold core 2, and is recessed inward from the surface of the mold core 2. The setting of the transition groove 22 can effectively guide the material so that its flow rate is uniform during the molding process, ensuring the uniformity of the glue output and reducing product quality defects.

[0049] The tail end of the mold core 2 is provided with a thread for connecting to external equipment. Through the threaded portion, the mold core 2 can be stably mounted on the molding equipment to ensure that the mold maintains correct positioning and a firm connection during operation.

[0050] A flat portion 23 is provided on both sides of the mold core 2, and the transition groove 22 is smoothly connected to the flat portion 23. The design of the flat portion 23 further enhances the structural strength of the mold and provides a more stable channel for material flow. Through the reasonable coordination between the flat portion 23 and the transition groove 22, the smoothness of material flow is ensured and the wear of the mold is reduced.

[0051] Although the above describes the illustrative specific implementation methods of the present application so that those skilled in the art can understand the present application, the present application is not limited to the scope of the specific implementation methods. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present application defined and determined by the attached claims, all application creations based on the concept of the present application are protected.
