Description

Technical Field

[0001] This utility model relates to the field of processing technology, specifically to a device for correcting the flatness of injection molded parts. Background Technology

[0002] The injection molding part flatness correction equipment is mainly used to correct flatness defects in injection molded or other plastic parts caused by factors such as uneven temperature and pressure during the molding process. By precisely controlling factors such as force and temperature, this equipment can effectively correct the flatness of plastic parts, ensuring they meet usage requirements.

[0003] In the prior art, after injection molding, the injection molded parts may warp due to uneven mold or cooling process, resulting in the surface flatness not meeting the standard requirements. Therefore, we propose an injection molded part flatness correction device. Utility Model Content

[0004] This utility model proposes a device for correcting the flatness of injection molded parts.

[0005] The technical solution of this utility model is as follows: A flatness correction device for injection molded parts includes a worktable, a frame fixedly connected to the top of the worktable, a hydraulic cylinder installed on the top of the frame, and a correction device installed on the side of the frame; the correction device includes a motor, the side of the motor fixedly connected to the telescopic end of the hydraulic cylinder, a reciprocating lead screw fixedly connected to the output shaft of the motor, a threaded sleeve threadedly connected to the circumferential surface of the reciprocating lead screw, a connecting rod fixedly connected to the circumferential surface of the threaded sleeve, a roller frame fixedly connected to the bottom of the connecting rod, a support shaft fixedly connected inside the roller frame, and a roller rotatably connected to the circumferential surface of the support shaft, the purpose of which is to ensure that the flatness meets the design requirements.

[0006] A limiting rod is fixedly connected to the side of the motor, and the side of the threaded sleeve passes through the circumference of the limiting rod. This design helps to prevent the threaded sleeve from rotating during displacement.

[0007] The end of the limiting rod away from the motor output shaft is fixedly connected to a limiting plate, and the circumferential surface of the reciprocating screw penetrates the side of the limiting plate. This design helps to limit the displacement distance of the threaded sleeve.

[0008] The hydraulic cylinder is initially in an unextended state, and the axis of the reciprocating screw is parallel to the top of the worktable. This design helps to ensure that the roller remains horizontal during the rolling process.

[0009] The top of the workbench is equipped with a collecting device, which includes a rotating shaft one. The rotating shaft one is fixedly connected to the end of the reciprocating screw away from the motor output shaft. A push rod is fixedly connected to the circumferential surface of the rotating shaft one. A fixing plate is fixedly connected to the side of the frame. A rotating shaft two is rotatably connected to the side of the fixing plate. A force-bearing plate is fixedly connected to the circumferential surface of the rotating shaft two. A connecting plate is fixedly connected to the circumferential surface of the rotating shaft two. A push plate is fixedly connected to the bottom of the connecting plate. The purpose of this device is to enable automatic material feeding and save manual labor.

[0010] A spring is fixedly connected to the side of the fixed plate, and the end of the spring away from the fixed plate is fixedly connected to the circumferential surface of the second rotating shaft. The purpose of this is to ensure that the second rotating shaft can automatically reset.

[0011] An inclined plate is fixedly connected to the side of the workbench, and a collection bin is provided on the side of the inclined plate to ensure that the injection molded parts can be automatically collected after being unloaded.

[0012] The force plate is located on the displacement trajectory of the push rod, and the spring is initially in a relaxed state. This design is beneficial because the force plate can be pushed during the rotation of the push rod.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] 1. This utility model utilizes the cooperation between components such as the motor, roller, and limiting plate of the straightening device. After the worker places the injection molded part on the worktable, the motor is adjusted to a suitable height by the hydraulic cylinder. The motor is then started, driving the reciprocating screw to rotate. The limiting rod drives the threaded sleeve to move, which in turn drives the roller frame and roller through the connecting rod, so that the roller contacts the top of the injection molded part and applies uniform pressure, thereby accurately straightening the flatness. This design achieves the effect of flatness straightening of the injection molded part, ensuring high precision in the flatness straightening process and improving product quality and production efficiency.

[0015] 2. This utility model utilizes the cooperation between components such as the push rod, push plate, and collection bin of the collection device. After the flatness of the injection molded part is corrected, the hydraulic cylinder moves the motor to its original position. The reciprocating screw drives the first rotating shaft to rotate, which in turn pushes the push rod to rotate, thereby pushing the force plate upward. Through the second rotating shaft, the connecting plate rotates, pushing the push plate and causing the injection molded part to slide into the collection bin. When the push rod leaves, the second rotating shaft returns to its original position via a spring. This design achieves the effect of automatically pushing and discharging the injection molded part, reducing manual intervention, improving work efficiency and automation, and ensuring the smooth transfer of the injection molded part to avoid damage.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example 1

[0026] like Figures 1-5As shown, this embodiment proposes a flatness correction device for injection molded parts, including a worktable 1, a frame 2 fixedly connected to the top of the worktable 1, a hydraulic cylinder 3 installed on the top of the frame 2, and a correction device 4 installed on the side of the frame 2; the correction device 4 includes a motor 41, the side of the motor 41 is fixedly connected to the telescopic end of the hydraulic cylinder 3, the output shaft of the motor 41 is fixedly connected to a reciprocating lead screw 42, a threaded sleeve 43 is threadedly connected to the circumferential surface of the reciprocating lead screw 42, a connecting rod 44 is fixedly connected to the circumferential surface of the threaded sleeve 43, a roller frame 45 is fixedly connected to the bottom of the connecting rod 44, a support shaft 46 is fixedly connected inside the roller frame 45, and a roller 47 is rotatably connected to the circumferential surface of the support shaft 46, the purpose of which is to ensure that the flatness meets the design requirements.

[0027] A limit rod 48 is fixedly connected to the side of the motor 41, and the side of the threaded sleeve 43 passes through the circumference of the limit rod 48. This design helps to prevent the threaded sleeve 43 from rotating during displacement.

[0028] The end of the limiting rod 48 away from the output shaft of the motor 41 is fixedly connected to the limiting plate 49, and the circumferential surface of the reciprocating screw 42 penetrates the side of the limiting plate 49. This design helps to limit the displacement distance of the threaded sleeve 43.

[0029] The hydraulic cylinder 3 is initially in an unextended state, and the axis of the reciprocating screw 42 is parallel to the top of the worktable 1. This design helps to ensure that the roller 47 is in a horizontal state during the rolling process.

[0030] In this embodiment, after the injection molding of the part is completed, the operator places the injection molding machine on the workbench 1. At this time, the hydraulic cylinder 3 moves the motor 41 to a suitable height and starts the motor 41. The output shaft of the motor 41 drives the reciprocating screw 42 to rotate. While the reciprocating screw 42 rotates, it drives the threaded sleeve 43 to move through the limit rod 48. While the threaded sleeve 43 moves, it drives the roller frame 45 to move through the connecting rod 44. The movement of the roller frame 45 drives the roller 47 to move through the support shaft 46. While the roller 47 moves, it contacts the top of the injection molded part, causing the roller 47 to rotate. While the roller rotates, it applies uniform pressure to the injection molded part to ensure the accuracy of the flatness correction process.

[0031] Example 2

[0032] like Figures 1-5As shown, based on the same concept as Embodiment 1 above, this embodiment also proposes that a collecting device 5 is provided on the top of the workbench 1. The collecting device 5 includes a first rotating shaft 51, which is fixedly connected to the end of the reciprocating screw 42 away from the output shaft of the motor 41. A push rod 52 is fixedly connected to the circumferential surface of the first rotating shaft 51. A fixing plate 53 is fixedly connected to the side of the frame 2. A second rotating shaft 54 ​​is rotatably connected to the side of the fixing plate 53. A force-bearing plate 55 is fixedly connected to the circumferential surface of the second rotating shaft 54. A connecting plate 56 is fixedly connected to the circumferential surface of the second rotating shaft 54. A push plate 57 is fixedly connected to the bottom of the connecting plate 56. The purpose is to enable automatic material feeding and save manual labor.

[0033] A spring 58 is fixedly connected to the side of the fixed plate 53. The end of the spring 58 away from the fixed plate 53 is fixedly connected to the circumferential surface of the second rotating shaft 54. The purpose is to ensure that the second rotating shaft 54 ​​can automatically reset.

[0034] An inclined plate 59 is fixedly connected to the side of the workbench 1. A collection bin 510 is provided on the side of the inclined plate 59 to ensure that the injection molded parts can be automatically collected after feeding.

[0035] The force plate 55 is located on the displacement trajectory of the push rod 52, and the spring 58 is initially in a relaxed state. This design is beneficial to push the force plate 55 during the rotation of the push rod 52.

[0036] In this embodiment, after the flatness of the injection molded part is corrected, the motor 41 is moved to its original position by the extension and retraction of the hydraulic cylinder 3. At this time, the reciprocating screw 42 rotates, driving the first rotating shaft 51 to rotate. The rotation of the first rotating shaft 51 drives the push rod 52 to rotate. During the rotation of the push rod 52, it pushes the force plate 55 upward. At this time, the force plate 55 is subjected to force and rotates through the second rotating shaft 54. While the second rotating shaft 54 ​​rotates, it drives the push plate 57 to rotate through the connecting plate 56. During the rotation of the push plate 57, it pushes the injection molded part after the flatness correction is completed, so that the injection molded part leaves the working area of ​​the worktable 1 and then slides down the inclined surface of the inclined plate 59 into the inside of the collection chamber 510. When the push rod 52 leaves the bottom of the force plate 55, the second rotating shaft 54 ​​is automatically reset by the elastic force of the spring 58, so that the push plate 57 is reset.

[0037] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
