Description

Technical Field

[0001] The invention belongs to the technical field of injection molding machines, and in particular relates to an injection molding device for improving the surface quality of a power line. Background Art

[0002] Power cords are essential items in modern life. During the production process of power cords, the wires need to be passed through the injection mold and pulled outward. The injection mold leaves a protective layer on the wires through the injection molding machine, thereby producing the power cords.

[0003] When the end of the power cord needs to be processed specifically, the end of the power cord is inserted between the movable platen assembly and the clamping device. The power cord is relatively long and the clamping device has a certain height. When the end of the power cord is inserted between the movable platen assembly and the clamping device, the other end of the power cord sags under its own gravity. The drooping of the other end of the power cord easily causes the end of the power cord to curl upward, so that the end of the power cord cannot be well inserted between the movable platen assembly and the clamping device, thereby affecting the injection molding of the end of the power cord to a certain extent.

[0004] To solve this problem, relevant technicians have proposed a power cord injection molding machine as shown in CN214163764U, which solves the problem by placing a padding block in the direction of the power cord going out, thereby lifting the wire. However, the power cord will inevitably rub against the padding block during the process of being dragged outward, and the surface of the wire that has just come out of the mold has not yet completely solidified, resulting in scratches during the friction process, which affects the quality of the power cord surface.

[0026] Further, in order to make the public have a better understanding of the present invention, some specific details are described in detail in the following detailed description of the present invention. For those skilled in the art, the present invention can be fully understood without the description of these details.

[0027] Please also read Figure 1-Figure 6 , this embodiment provides an injection molding device for improving the surface quality of a power cord, comprising a frame 1, a blower 2, a baffle mechanism 3, a sliding frame 4, a limiting mechanism 5 and a driven component 6; The frame 1 is provided with a plurality of air outlets 13 which are interconnected, and the hair dryer 2 is provided on the frame 1 and can blow air to the air outlet 13; specifically, the frame 1 is provided with an air inlet duct and an air outlet duct, the air inlet duct is connected to the hair dryer 2, a plurality of air outlet ducts are provided and are respectively connected to the air inlet duct, and one end of the air outlet duct away from the air inlet duct is the air outlet 13. In this embodiment, air outlets 13 are provided on both sides of the sliding frame 4, and air can be blown by a single hair dryer 2 or hair dryers 2 on each side. It should also be understood that the frame 1 includes a frame body and related structures such as an injection molding machine.

[0028] The frame 1 is also provided with a plurality of baffle slots 11 corresponding one to the air outlets 13, and a baffle mechanism 3 is slidably connected in the baffle slots 11, and the baffle mechanism 3 can close the corresponding air outlet 13; specifically, the baffle mechanism 3 slides toward the air outlet 13 to close the air outlet 13, and slides away from the air outlet 13 to open the air outlet 13.

[0029] The sliding frame 4 is a hollow frame and is slidably connected to the frame 1. The sliding frame 4 can be opposite to the air outlet 13, and the sliding frame 4 is provided with an air outlet; specifically, the sliding frame 4 can switch back and forth between the air outlets 13, so that the wind from the air outlet 13 is blown out from the air outlet through the sliding frame 4. The sliding frame 4 is preferably a door-shaped or H-shaped frame, and its air outlet is a long strip hole with a long straight edge at the top, and is oriented toward the top, so that the air can be blown upward to blow up the power cord. In this embodiment, the sliding frame 4 is an H-shaped frame, and its two bottom ends correspond to the air outlet 13 on one side respectively. A baffle is provided in the middle of the long strip hole to prevent the wind on both sides from directly colliding, and preferably, the part directly connected to the air outlet 13 has an inclination toward the long strip hole.

[0030] The limiting assembly is rotatably arranged on the sliding frame 4, and the driven assembly 6 is slidably arranged on the frame 1. The frame 1 is provided with fixed screw grooves 12 corresponding to the air outlets 13 one by one. The rotation of the limiting assembly can be screwed with the fixed screw grooves 12, and the baffle mechanism 3 on the same side away from the limiting mechanism 5 is driven by the driven assembly 6 to slide toward the air outlet 13. Specifically, the air outlet 13 is arranged on both sides of the sliding frame 4, and both sides of the sliding frame 4 are provided with limiting mechanisms 5. Through the rotation of the limiting mechanism 5 on the sliding frame 4, the remaining baffle mechanisms 3 on the same side except the baffle mechanism 3 closest to the limiting mechanism 5 among all the baffle mechanisms 3 on the same side slide toward the corresponding air outlets 13 through the transmission of the driven mechanism, thereby closing the remaining air outlets 13 on the same side except the ones connected to the sliding frame 4.

[0031] In the present application, air is blown toward each air outlet 13 by a hair dryer 2, and the sliding frame 4 is moved to a desired position, so that the sliding frame 4 can blow air upward at the desired position, and the power cord coming out of the mold is given an upward force by the upward blowing, thereby achieving support for the power cord in the air. Moreover, since the power cord just coming out of the mold has no contact with other hard objects during this process, compared with the prior art that needs to be supported by hard objects, the damage to the surface quality caused by the friction of the power cord just coming out of the mold with hard objects is reduced, thereby improving the surface quality of the power cord.

[0032] In addition, the position fixing mechanism shown in the present application can simultaneously close the remaining air outlets 13 while fixing the position, making the operation more convenient.

[0033] In other schemes, the baffle mechanism 3 includes a baffle assembly 31 and a gear ring 32; the baffle assembly 31 is slidably disposed in the baffle slide groove 11 and is elastic; the gear ring 32 is rotatably connected to the frame 1, and the rotation of the gear ring 32 can drive the adjacent baffle assembly 31 to slide, and drive the driven assembly 6 to slide, and the sliding of the driven assembly 6 can drive the remaining gear rings 32 on the same side to rotate; a fixed screw groove 12 is provided in the center of the gear ring 32, and a pushing groove 321 is provided on the top of the gear ring 32. The rotation of the driven assembly 6 can squeeze the baffle assembly 31, so that the baffle assembly 31 is away from the gear ring 32, and then the gear ring 32 is driven to rotate through the pushing groove 321.

[0034] Specifically, when the position of the sliding frame 4 is limited by rotating the limiting mechanism 5, it is necessary to align with the fixed screw groove 12, and then by rotating, the limiting mechanism 5 pushes the baffle assembly 31 closest to it to be compressed, so that it is away from the corresponding gear ring 32, and maintains the compressed state. When the limiting mechanism 5 continues to rotate and inserts the pushing groove 321 to drive the gear ring 32 to rotate, since the compressed baffle assembly 31 is away from the gear ring 32, the baffle assembly 31 cannot slide under the drive of the gear ring 32, and the rotation of the gear ring 32 drives the sliding of the driven assembly 6, and the sliding of the driven assembly 6 drives the remaining gear rings 32 on the same side to rotate, and then drives the remaining baffle assemblies 31 on the same side to slide toward the air outlet 13, thereby closing the air outlet 13. In this way, the fixed sliding frame 4 can close the air outlet 13 that is not needed.

[0035] In other schemes, the baffle assembly 31 includes a sliding plate 311, a connecting spring 312, a first telescopic rod 313, a sliding rack 314 and a baffle body 315; the sliding plate 311 is slidably connected in the baffle slide groove 11, and is connected to the sliding rack 314 through the connecting spring 312, one end of the first telescopic rod 313 is connected to the sliding plate 311, and the other end is connected to the sliding rack 314; the sliding rack 314 can engage with the gear ring 32, and the baffle body 315 is fixedly provided at one end of the sliding rack 314 close to the air outlet 13.

[0036] Specifically, the size of the baffle body 315 is not smaller than the air outlet 13. During the rotation of the limiting mechanism 5, the sliding rack 314 is pressed into the baffle slide groove 11, so that the sliding rack 314 is disengaged from the meshing state with the gear ring 32. When the sliding rack 314 is reset by the connecting spring 312, it can mesh with the gear ring 32 again.

[0037] In other solutions, the driven assembly 6 includes a driven slider 61 and a driven rack 62 ; the driven slider 61 is slidably connected to the frame 1 , and the driven rack 62 is fixed on the driven slider 61 and meshes with the gear ring 32 .

[0038] Specifically, the driven rack 62 is meshed with all the gear rings 32 on the same side at the same time, and the top surface of the driven slider 61 is not lower than the top surface of the sliding rack 314 that is not squeezed by the limiting mechanism 5, that is, the bottom surface of the driven rack 62 is not lower than the top surface of the sliding rack 314 that is not squeezed by the limiting mechanism 5, so that the driven rack 62 does not interfere with the sliding rack 314 when sliding.

[0039] In other schemes, the limiting mechanism 5 includes a connecting plate 51, a rotating rod 52, an extrusion assembly 53 and a pushing assembly 54; the connecting plate 51 is fixedly mounted on the sliding frame 4, the rotating rod 52 is screwed to the connecting plate 51, and can be screwed to the fixed screw groove 12; the extrusion assembly 53 is rotatably connected to the rotating rod 52, and can extrude the baffle assembly 31, specifically, the sliding rack 314 of the extrusion baffle mechanism 3; the pushing assembly 54 is fixedly mounted on the rotating rod 52, the pushing assembly 54 can be inserted into the pushing groove 321, and drive the gear ring 32 to rotate, and the top of the pushing groove 321 has a bell mouth.

[0040] Specifically, threads are provided at the bottom end of the rotating rod 52 and one side close to the connecting plate 51. The extrusion assembly 53 is rotatably connected to the rotating rod 52 and rises and falls with the rotation of the rotating rod 52, specifically straight up and down. The pushing assembly 54 enters the pushing groove 321 through the bell mouth of the pushing groove 321 when descending, and drives the gear ring 32 to rotate. Specifically, the pushing groove 321 includes a bell mouth at the top and a straight groove connected to the bell mouth, and the diameter of the straight groove is equal to or slightly larger than the insertion end of the pushing assembly 54.
