[0008] Preferably, a mold-changing assembly is provided between the first moving mold blank and the second moving mold blank. The mold-changing assembly includes a limiting sleeve, which is disposed between the first moving mold blank and the second fixed mold blank. A connecting sleeve is fixedly connected to the outer wall of the first moving mold blank. The connecting sleeve is fixedly connected to the outer walls of the first and second fixed mold blanks respectively. A first spring is fixedly connected to the left side of the limiting sleeve.

[0012] This invention provides a molding die for forming a transparent sheath for data cables. It has the following beneficial effects: 1. The data cable's icy transparent sheath molding mold uses SR136 steel for both the first and second mold bodies, and the mold cavity is mirror-polished. The injection mold adopts a split design and is equipped with a horn gate for injection molding. This solves the problem of glue marks on the outer mold of the icy lens surface, and also improves the icy lens effect, resulting in a better appearance quality for the final molded part.

[0013] 2. The data cable's transparent sheath molding die, through the rotation of a motor to drive the switching of the positions of two moving modules, can directly inject the transparent sheath outer mold onto the outside of the mirror shell, improving the overall molding efficiency. At the same time, if the mirror shell is not completely cooled, injection molding on its surface can avoid the cooling rate of the material during the injection molding of the transparent sheath outer mold, which can reduce weld lines, improve the surface gloss of the appearance parts, and improve the appearance quality of the molded parts.

[0014] 3. In the molding die for the data cable sheath, the movable heat-conducting block is pushed into the mold rod by air during mold closing. The movable heat-conducting block heats the mold rod, slowing down the drop in material temperature during injection molding. This reduces weld lines on the surface of the data cable sheath after molding, thereby improving the surface gloss of the appearance part and enhancing the appearance quality of the molded part.

[0015] 4. The data cable ice-clear sheath molding mold, after injection molding, moves one end of the movable heat-conducting block to the limiting rod, and draws cold air from the outside into the mold rod, thereby cooling the inner wall of the molded part. This allows the inner wall of the molded part to shrink slightly, reducing the friction between the molded part and the heat sink during demolding, and improving the molding quality of the inner wall of the molded part.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0019] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0020] Example 1: Please refer to Figure 1-8 This invention provides a technical solution: a data cable ice-clear sheath molding mold, including a first moving mold blank 1, a first fixed mold blank 2 disposed on the right side of the first moving mold blank 1, a second moving mold blank 3 disposed on the back of the first moving mold blank 1, a second fixed mold blank 4 disposed on the right side of the second moving mold blank 3, a first mold body disposed between the first moving mold blank 1 and the first fixed mold blank 2, and a second mold body disposed between the second moving mold blank 3 and the second fixed mold blank 4. Both the first mold body and the second mold body adopt a split design, and the split structure of the mold is provided with threaded holes of the same specification, so that the mold can be fixed on the corresponding template by corresponding bolts; The first mold body is used to form the plastic mirror shell of the data cable, and the second mold body is used to form the outer mold of the transparent sheath. The first mold body and the second mold body are made of SR136 steel.

[0021] The cavities of the upper and lower molds of the first mold body and the second mold body are mirror polished. The first mold body is provided with an overflow venting groove 21, which helps to vent during injection molding and solve the problem of air marks on the appearance, resulting in a better mirror effect. Both the first mold body and the second mold body are provided with flow channels for cooling water. The second mold body is provided with a horn-shaped runner 41, and a horn-shaped gate 42 is provided at the connection between the horn-shaped runner 41 and the cavity. Both the first mold body and the second mold body are designed as separate parts, which helps to vent during injection molding.

[0022] A moving module 51 is provided between the upper and lower molds of the first mold body and the second mold body. A mold rod 54 is fixedly connected to the outside of the moving module 51. A stripping template 52 is movably connected to the outer wall of the mold rod 54. An ejector rod 53 is movably connected to the inside of the moving module 51, and the ejector rod 53 passes through the moving module 51 and is fixedly connected to the stripping template 52.

[0023] By pushing the first moving mold blank 1 and the second moving mold blank 3 with the injection molding equipment, the first mold body and the second mold body are closed. Then the injection molding equipment performs injection molding, injecting the material into the cavity through the main runner, and then through the horn runner 41 and the horn gate 42 into the cavity. This can solve the problem of the appearance of the outer mold of the ice lens surface, and the ice lens surface effect is better. After the injection molding is completed, external cooling water enters the runner of the mold to cool the material inside the mold and form it.

[0024] Example 2: Please refer to Figure 1-9 Based on Embodiment 1, the present invention provides a technical solution: A mold changing assembly 6 is provided between the first moving mold blank 1 and the second moving mold blank 3. The mold changing assembly 6 includes a limiting sleeve 61, which is located between the first moving mold blank 1 and the second fixed mold blank 4. A connecting sleeve 67 is fixedly connected to the outer wall of the first moving mold blank 1. The connecting sleeve 67 is fixedly connected to the outer walls of the first fixed mold blank 2 and the second fixed mold blank 4 respectively. A first spring 66 is fixedly connected to the left side of the limiting sleeve 61. A movable frame 62 is fixedly connected to the left side of the first spring 66. The movable frame 62 is movably connected to the limiting sleeve 61. A rotary motor 63 is fixedly connected to the left side of the movable frame 62. The rotary motor 63 is fixedly connected to the movable frame 62 through an output shaft. A heat sink 64 is fixedly connected to the top of the rotary motor 63. Two connecting rods 65 are fixedly connected to the outer wall of the rotary motor 63. The outer ends of the connecting rods 65 are fixedly connected to the corresponding moving module 51 respectively. The heat sink 64 can dissipate heat from the rotating motor 63 during operation.

[0025] A first spring 66 is provided on the outside of the connecting rod 65. One end of the first spring 66 is fixedly connected to the outer wall of the connecting rod 65, and the telescopic end of the first spring 66 is fixedly connected to the ejector rod 53.

[0026] During mold closing, the first moving mold blank 1 and the second moving mold blank 3 will push the corresponding moving module 51 through the mold to close the mold, causing the mold rod 54 to move to the corresponding mold for injection molding. During this process, the first spring 66 will be compressed by the movable frame 62 at the bottom of the rotating motor 63. After molding, the mold will be separated. The first spring 66 will push the rotating motor 63, and further push the moving module 51 through the connecting rod 65. Then, the first spring 66 between the second moving mold blank 3 and the second fixed mold blank 4 will push the ejector rod 53. The corresponding ejector plate 52 is moved so that the ejector plate 52 demolds the molded part on the outer wall of the mold rod 54. At the same time, the waste material in the mold is removed by the external equipment. Then, the motor 63 drives itself to rotate and change the position of the two moving modules 51. Then the mold can be closed again. It can directly inject the ice-clear sleeve outer mold into the outer side of the mirror shell, which improves the overall molding efficiency. At the same time, the mirror shell is not completely cooled. Injecting on its surface can avoid the cooling rate of the material during the injection of the ice-clear sleeve outer mold, which can reduce weld lines and improve the surface gloss of the appearance part.

[0027] Example 3: Please refer to Figure 1-11 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: An auxiliary component 7 is fixedly connected to the outer wall of the moving module 51. The auxiliary component 7 includes a heat-conducting connecting pipe 72, which is connected to the corresponding mold rod 54. A movable heat-conducting block 73 is movably connected inside the heat-conducting connecting pipe 72. An electric heating sleeve 71 is fixedly connected to the outer wall of the heat-conducting connecting pipe 72. During the injection molding process, the electric heating sleeve 71 can heat the movable heat-conducting block 73 inside the heat-conducting connecting pipe 72.

[0028] A limiting rod 74 is fixedly connected inside the heat-conducting connecting pipe 72 on the side of the movable heat-conducting block 73 near the limiting sleeve 61. A gas control box 76 is fixedly connected to the outer wall of the rotating motor 63. A push plate 78 is movably connected inside the gas control box 76. A second spring 77 is fixedly connected to the left side of the push plate 78. The left side of the second spring 77 is fixedly connected to the inner wall of the gas control box 76. A push frame 79 is fixedly connected to the right side of the push plate 78 on the left side of the connecting sleeve 67. A gas guide pipe 75 is fixedly connected to the side of the heat-conducting connecting pipe 72 near the limiting sleeve 61. The other end of the gas guide pipe 75 is fixedly connected to the top of the gas control box 76.

[0029] During mold closing, the rotating motor 63 is pressed down by the mold via the connecting rod 65. During this process, the rotating motor 63 drives the corresponding air control box 76 to move downwards. Because the bottom of the pusher frame 79 is blocked by the connecting sleeve 67, the pusher plate 78 gradually moves upwards relative to the air control box 76 as it moves downwards. This causes the air level inside the air control box 76 to gradually decrease, allowing the air inside the air control box 76 to be pushed into the heat-conducting connecting pipe 72 through the air guide pipe 75. This air then pushes the movable heat-conducting block 73 into the mold rod 54. As the movable heat-conducting block 73 is heated, it heats the mold rod 54, slowing down the temperature drop of the material during injection molding, reducing weld lines, and improving the surface finish of the parts. After injection molding is completed, the rotating motor 63 moves downward under the push of the first spring 66, and the push plate 78 moves downward relative to the air control box 76 under the push of the second spring 77. This allows the air control box 76 to draw the air inside the movable heat-conducting block 73 back into the air control box 76 through the air guide pipe 75, causing one end of the movable heat-conducting block 73 to move to the limiting rod 74. At the same time, it can draw cold air from the outside into the mold rod 54, cooling the mold rod 54 and thus cooling the inner wall of the molded injection part. This allows the inner wall of the molded part to shrink slightly, reducing the friction between the molded part and the heat sink 64 when the first spring 66 pushes the ejector plate 52 through the ejector rod 53 for demolding, thereby improving the molding quality of the inner wall of the molded part.

[0030] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
