Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to a continuous injection molding device for a double-insulated high-speed data transmission cable. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. Its advantages include high production speed and efficiency, automated operation, a wide variety of colors and shapes (from simple to complex), and sizes ranging from large to small. It also produces precise dimensions, facilitates product updates, and can create complex shapes. Injection molding is suitable for mass production and the molding of complex products. In the production of wire and cable products in the intelligent manufacturing equipment industry, after the cable core is manufactured, a protective sleeve needs to be processed. Currently, injection molding is often used to process the cable protective sleeve to improve cable performance and safety. The injection mold head matches the cable size. When the mold head connects to the injection tube, the adhered hot-melt plastic is discharged from the groove in the mold head, wrapping the outer surface of the cable that passes through the mold head. As the cable moves, it enters the cooling tank to complete the injection molding process on the cable surface.

[0003] In existing continuous injection molding processes for data cables, the cable injection is performed by installing a compatible injection mold head. The hot-melt plastic extruded from the mold head continuously adheres to the data cable. Since the data cable is in a state of motion under external traction, the local bonding performance between the hot-melt plastic and the cable is poor. This can lead to stretching of the extruded hot-melt plastic and the moving cable, causing changes in the thickness of the hot-melt plastic covering the data cable and affecting its performance. Therefore, there is an urgent need for a continuous injection molding device for double-insulated high-speed data transmission cables to solve this problem. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the user can start the conveyor motor to make the conveyor worm rotate. The conveyor worm meshes with the conveyor worm wheel. The bottom wheel is mounted on the top plate through a bent rod. At this time, the conveyor worm wheel will drive the extension rod to make the bottom wheel rotate. With the cooperation of the top wheel, the data cable will pass between the top wheel and the bottom wheel, causing the top wheel and the bottom wheel to rotate. At this time, the entire device can realize the function of pulling and conveying the data cable to the left.

[0016] 2. In this invention, when the top wheel rotates, in the initial state of the return spring, the tension of the return spring can pull the sliding plate to make the extrusion rod slide out of the inner cavity of the liquid storage tank. Since the outer side of the extrusion rod is set as an arc surface, when the extrusion rod contacts the side wall of the data cable, the extrusion rod will retract into the inner cavity of the liquid storage tank, causing the sliding plate to move towards the inner side wall of the inner cavity of the liquid storage tank. At this time, the return spring is stretched, and the overall volume of the inner cavity of the liquid storage tank decreases. Under the action of the one-way water valve in the inner cavity of the pressure relief pipe, the plasma treatment liquid in the liquid storage tank can be sprayed onto the side wall of the data cable through the pressure relief pipe, which can activate the surface of the data cable, increase polarity and roughness, so as to enhance the adhesion of the subsequent injection molding layer and improve the quality of injection molding of the data cable.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 This invention provides a technical solution for a continuous injection molding device for a double-insulated high-speed data transmission cable: A continuous injection molding device for a double-insulated high-speed data transmission cable includes a base 1, a limit rod 2 fixedly installed on the rear side of the upper end face of the base 1, a top seat 3 fixedly installed on the upper end face of the limit rod 2, and an injection molding seat 5 fixedly installed on the left end face of the top seat 3 via a connecting rod 4. It also includes: Adjustment component 6 is disposed on the upper end face of top seat 3; Conveying assembly 7 is disposed on the side wall of limiting rod 2; Spray assembly 8 is disposed between base 1 and top seat 3; Injection assembly 9 is disposed on the side wall of injection base 5.

[0021] Furthermore, the adjustment assembly 6 includes a bidirectional screw 61 rotatably mounted on the front side of the upper end face of the base 1, and a support plate 62 fixedly mounted on the front side of the upper end face of the top seat 3. An adjustment worm gear 63 is rotatably mounted in the inner cavity of the support plate 62. An adjustment worm wheel 64 is rotatably mounted on the front side of the upper end face of the top seat 3. The upper end face of the bidirectional screw 61 passes through the top seat 3 and is fixedly connected to the adjustment worm wheel 64. Movable seats 65 are provided on both the upper and lower sides of the side wall of the bidirectional screw 61 and the limit rod 2. An adjustment motor 66 is fixedly mounted on the front side of the upper end face of the top seat 3 through a frame. The upper and lower threads of the bidirectional screw 61 are in opposite directions. The output shaft of the adjusting motor 66 is fixedly connected to the adjusting worm 63. The adjusting worm 63 is meshed with the adjusting worm wheel 64. The movable seat 65 is threadedly connected to the bidirectional screw 61.

[0022] It should be noted that the user can start the adjusting motor 66 to make the adjusting worm 63 rotate. Since the adjusting worm 63 is meshed with the adjusting worm wheel 64, the adjusting worm wheel 64 can drive the bidirectional screw 61 to rotate. Since the upper and lower threads of the bidirectional screw 61 are opposite, the upper and lower movable seats 65 can slide in opposite directions on the side wall of the bidirectional screw 61. The crossbar 67 fixedly installed between the movable seats 65 will drive the support 68 to move up and down. At this time, the bottom wheel 72 and the top wheel 78 will move closer or further apart, so that the whole device can be used with data cables of different sizes.

[0023] Furthermore, the conveying assembly 7 includes a bent rod 71 fixedly installed on the front side of the upper end face of the base plate 610, and a bottom wheel 72 rotatably installed on the side wall of the bent rod 71.

A conveying motor 75 is fixedly installed on the upper end face of the base plate 610 through a frame, and a conveying worm gear 76 is fixedly installed on the output shaft end of the conveying motor 75. The conveying worm 76 is meshed with the conveying worm wheel 74. Liquid inlet pipes 77 are fixedly installed on the front and rear sides of the lower end of the top plate 69. A top wheel 78 is rotatably installed between the liquid inlet pipes 77 on the front and rear sides. A data cable is provided between the bottom wheel 72 and the top wheel 78.

[0024] It should be noted that the user can start the conveyor motor 75 to make the conveyor worm 76 rotate. The conveyor worm 76 meshes with the conveyor worm wheel 74. The bottom wheel 72 is rotated and installed above the base plate 610 through the bent rod 71. At this time, the conveyor worm wheel 74 will drive the extension rod 73 to make the bottom wheel 72 rotate. With the cooperation of the top wheel 78, the data cable will pass through the top wheel 78 and the bottom wheel 72, causing the top wheel 78 and the bottom wheel 72 to rotate. At this time, the entire device can realize the function of pulling and conveying the data cable to the left.

[0025] Furthermore, the spray assembly 8 includes a liquid storage tank 81 opened on the side wall of the top wheel 78, and a sliding plate 82 slidably installed on the inner side wall of the liquid storage tank 81. A squeezing rod 83 is fixedly installed on the side wall of the sliding plate 82. The outer side of the squeezing rod 83 is set as an arc surface. A return spring 84 is wound on the side wall of the squeezing rod 83. Liquid storage boxes 85 are fixedly installed on the front and rear sides of the upper end face of the top plate 69. One end of the return spring 84 is fixedly installed on the bottom surface of the inner cavity of the liquid storage tank 81, and the other end of the return spring 84 is fixedly installed on the side wall of the sliding plate 82. The pressure relief pipe 821 is fixedly installed on the squeezing rod 83 and the inner cavity of the sliding plate 82. The inner cavity of the pressure relief pipe 821 is provided with a one-way water valve with an outlet to the outside. The liquid inlet pipe 77 is connected to the liquid storage tank 81 and the liquid storage box 85. The inner cavity of the liquid inlet pipe 77 is provided with a one-way water valve with an outlet to the inner cavity of the liquid storage tank 81.

[0026] It should be noted that when the top wheel 78 rotates, in the initial state of the return spring 84, the tension of the return spring 84 can pull the sliding plate 82 to make the extrusion rod 83 slide out of the inner cavity of the liquid storage tank 81. Since the outer side of the extrusion rod 83 is set as an arc surface, when the extrusion rod 83 contacts the side wall of the data cable, the extrusion rod 83 will retract into the inner cavity of the liquid storage tank 81, causing the sliding plate 82 to move towards the inner side wall of the inner cavity of the liquid storage tank 81. At this time, the return spring 84 is stretched, and the overall volume of the inner cavity of the liquid storage tank 81 decreases. Under the action of the one-way water valve in the inner cavity of the pressure relief pipe 821, the plasma treatment liquid in the liquid storage tank 81 can be sprayed onto the side wall of the data cable through the pressure relief pipe 821, which can activate the surface of the data cable, increase polarity and roughness, so as to enhance the adhesion of the subsequent injection molding layer and improve the quality of injection molding of the data cable.

[0027] Furthermore, the injection molding assembly 9 includes a thermoplastic inlet pipe 91 fixedly installed on the upper part of the outer side wall of the injection molding base 5, a thermoplastic hole 92 is provided on the inner side wall of the injection molding base 5, and an injection sleeve 93 is fixedly installed on the left end face of the injection molding base 5. The injection sleeve 93 is hollow. A heat insulation ring 94 is fixedly installed on the right side of the inner cavity of the injection sleeve 93. A water inlet pipe 95 is fixedly installed on the lower part of the outer wall of the injection sleeve 93, and a water outlet pipe 96 is fixedly installed on the upper part of the outer wall of the injection sleeve 93.

[0028] It should be noted that as the data cable is continuously conveyed to the left, the user can inject hot melt plastic into the inner cavity of the injection molding seat 5 through the thermoplastic inlet pipe 91. The high-temperature and high-pressure hot melt plastic can adhere to the surface of the data cable through the thermoplastic hole 92 to achieve injection molding of the data cable. At the same time, an external water pump can be started to inject cold water into the inner cavity of the injection sleeve 93 through the water inlet pipe 95. After circulating in the injection sleeve 93, hot water is discharged from the water outlet pipe 96, which can cool down the high-temperature hot melt plastic and accelerate the cooling of the hot melt plastic after it covers the surface of the data cable, effectively improving the efficiency of the entire device in injection molding the data cable.

[0029] Working principle: During operation, the user can start the regulating motor 66 to make the regulating worm 63 rotate. Since the regulating worm 63 is meshed with the regulating worm wheel 64, the regulating worm wheel 64 can drive the bidirectional screw 61 to rotate. Since the upper and lower threads of the bidirectional screw 61 are opposite, the upper and lower movable seats 65 can slide in opposite directions on the side wall of the bidirectional screw 61. The crossbar 67 fixedly installed between the movable seats 65 will drive the support 68 to move up and down. At this time, the bottom wheel 72 and the top wheel 78 will move closer or further apart, so that the whole device can be used for data cables of different sizes. Afterwards, the user can start the conveyor motor 75 to make the conveyor worm 76 rotate. The conveyor worm 76 meshes with the conveyor worm wheel 74. The bottom wheel 72 is rotated and installed above the base plate 610 through the bent rod 71. At this time, the conveyor worm wheel 74 will drive the extension rod 73 to make the bottom wheel 72 rotate. With the cooperation of the top wheel 78, the data cable will pass through the top wheel 78 and the bottom wheel 72, causing the top wheel 78 and the bottom wheel 72 to rotate. At this time, the entire device can realize the function of pulling and conveying the data cable to the left. When the top wheel 78 rotates, in the initial state of the return spring 84, the tension of the return spring 84 can pull the sliding plate 82 to make the squeezing rod 83 slide out of the inner cavity of the liquid storage tank 81. Since the outer side of the squeezing rod 83 is set as an arc surface, when the squeezing rod 83 contacts the side wall of the data cable, the squeezing rod 83 will retract into the inner cavity of the liquid storage tank 81, causing the sliding plate 82 to move towards the inner side wall of the inner cavity of the liquid storage tank 81. At this time, the return spring 84 is stretched, and the overall volume of the inner cavity of the liquid storage tank 81 decreases. Under the action of the one-way water valve in the inner cavity of the pressure relief pipe 821, the volume of the liquid in the liquid storage tank 81 at this time... The plasma treatment liquid can be sprayed onto the side wall of the data cable through the pressure relief pipe 821, which can activate the surface of the data cable, increase polarity and roughness, thereby enhancing the adhesion of the subsequent injection molding layer and improving the quality of injection molding of the data cable. When the extrusion rod 83 disengages from the data cable, the return spring 84 will be reset, and the volume of the inner cavity of the liquid storage tank 81 will increase. At this time, the plasma treatment liquid in the inner cavity of the liquid storage box 85 can enter the liquid storage tank 81 through the liquid inlet pipe 77, thereby replenishing the plasma treatment liquid content in the liquid storage tank 81 and ensuring that the entire spray assembly 8 can be used continuously. As the data cable is continuously fed to the left, the user can inject hot melt plastic into the inner cavity of the injection base 5 through the thermoplastic inlet pipe 91. The high-temperature and high-pressure hot melt plastic can adhere to the surface of the data cable through the thermoplastic hole 92 to achieve the injection molding of the data cable. At the same time, an external water pump can be started to inject cold water into the inner cavity of the injection sleeve 93 through the water inlet pipe 95. After circulating in the injection sleeve 93, hot water is discharged from the water outlet pipe 96, which can cool down the high-temperature hot melt plastic and accelerate the cooling of the hot melt plastic after it covers the surface of the data cable. This effectively improves the efficiency of the entire device in injection molding the data cable. A heat insulation ring 94 is fixedly installed on the right side of the inner cavity of the injection sleeve 93 to avoid violent heat exchange between the injection base 5 and the injection sleeve 93, thus ensuring the quality of the data cable injection molding.

[0030] Finally, it should be noted that the above content is only used to illustrate the technical solution of the present invention, and is not intended to limit the scope of protection of the present invention. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of the present invention do not depart from the essence and scope of the technical solution of the present invention.
