Description

Technical Field

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

[0002] During the production of injection molded parts, due to various factors such as mold design defects, manufacturing errors, or improper setting of injection molding process parameters, the surface of the injection molded parts may exhibit flatness deviations such as unevenness and wavy texture. These deviations not only reduce the appearance quality of the injection molded parts but may also adversely affect their actual performance. Currently widely used injection molded part flatness correction devices are quite cumbersome in the feeding and unloading process of injection molded parts. After each injection molded part has undergone the correction process and reached the required flatness, the operator must first manually remove it from the correction area before a new injection molded part can be placed in the designated position to start the next round of feeding and correction operations. The material handling operation reduces the overall production efficiency. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 6This utility model provides a technical solution: a flatness correction device for injection molded parts, including an operation box 1. An inner fixed support 2 is fixedly connected inside the operation box 1. Two movable support plates 5 are slidably connected to the top of the inner fixed support 2. A cylinder 7 is installed on the top of the operation box 1. A first linear module 8 is fixedly connected to the output end of the cylinder 7. A second linear module 10 is installed on the movable slide of the first linear module 8. A bottom sliding box 11 is installed on the movable slide of the second linear module 10. Three electrically heated pressure rollers 12 are equidistantly rotatably connected inside the second linear module 10. A blower side is fixedly connected to one side of the bottom sliding box 11. The inner fixed support 2 of box 13 is symmetrically equipped with an adjusting screw 3. The outer side of the adjusting screw 3 is threadedly connected to a movable slider 4. The movable slider 4 is slidably connected to the inner fixed support 2. The top of the movable slider 4 is fixedly connected to the movable support plate 5. The movable slider 4 is equipped with a limit slide rod 6 inside. The limit slide rod 6 is fixedly connected to the inner fixed support 2. The rotation of the adjusting screw 3 drives the outer movable slider 4 to move. The movable slider 4 drives the movable support plate 5 at the top of the inner fixed support 2 to move, thereby completing the movement and adjustment of the position of the injection molded part and performing loading and unloading processing of the injection molded part on the movable support plate 5.

[0020] One side of the inner fixed support 2 is fixedly connected to a connecting box 19. The adjusting screw 3 is rotatably connected to the connecting box 19. The outer sides of the two adjusting screws 3 are fixedly connected to pulleys 20. The two pulleys 20 are connected by belt drive. A motor 21 is installed on one side of the connecting box 19. One adjusting screw 3 is fixedly connected to the output end of the motor 21. By setting the pulleys 20, the output end of the motor 21 drives one adjusting screw 3 to rotate. One adjusting screw 3 drives the outer pulley 20 to rotate. One pulley 20 drives the other pulley 20 to rotate synchronously through the belt, thus completing the rotation of the two adjusting screws 3. The two adjusting screws 3 are symmetrically arranged in opposite directions. One adjusting screw 3 drives the outer sliding block 4 to move in the opposite direction as the other adjusting screw 3 drives the outer sliding block 4 to move in the opposite direction, thus adjusting the two moving support plates 5.

[0021] The bottom sliding box 11 is fixedly connected to a fixed side box 18 on one side. The three electric heating pressure rollers 12 are rotatably connected to the fixed side box 18. One of the electric heating pressure rollers 12 is fixedly connected to a double groove pulley 16 on the outside. The other two electric heating pressure rollers 12 are fixedly connected to driven pulleys 17 on the outside. The two driven pulleys 17 and the double groove pulley 16 are connected by belt drive. When the double groove pulley 16 rotates, it drives the two driven pulleys 17 to rotate synchronously through the belt, thereby adjusting the synchronous rotation of the three electric heating pressure rollers 12.

[0022] Among them, a second motor 22 is installed on one side of the fixed side box 18, and one of the electric heating rollers 12 is fixedly connected to the output end of the second motor 22. The output end of the second motor 22 drives one of the electric heating rollers 12 to rotate.

[0023] Among them, a blower 14 is installed on one side of the control box 1. The input end of the blower 14 is fixedly connected to a filter tube 15. The output end of the blower 14 is connected to the blower side box 13 through a flexible air tube. The air intake is filtered through the filter tube 15 at the input end of the blower 14 to prevent impurities from entering.

[0024] Among them, the top of the first linear module 8 is symmetrically fixedly connected with a limit rod 9, the limit rod 9 is slidably connected to the operation box 1, and the operation box 1 is equipped with multiple ventilation nets 23, which ensure the air outlet of the operation box 1.

[0025] Specifically, in use, the injection molded part to be corrected is placed on one of the movable support plates 5. The output end of the first motor 21 drives one of the adjusting screws 3 and the outer first pulley 20 to rotate. One of the first pulleys 20 drives the other first pulley 20 and the inner adjusting screw 3 to rotate via a belt. This completes the positional movement of the outer movable slider 4 and the top movable support plate 5 driven by the adjusting screw 3, adjusting the positions of the two movable support plates 5 in opposite directions. The movable slide of the second linear module 10 drives the bottom sliding box 11 and the electrically heated pressure roller 12 to adjust their positions. The electrically heated pressure roller 12 reaches below the injection molded part, and the other movable support plate 5 moves to the next position. When the support plate 5 reaches the outside, it completes the loading and unloading of the injection molded parts. The output end of the cylinder 7 drives the first linear module 8, the second linear module 10, and the bottom sliding box 11 to move downward. The moving slide of the first linear module 8 drives the second linear module 10, the bottom sliding box 11, and the electric heating pressure roller 12 to move. The electric heating pressure roller 12 performs flatness correction on the injection molded parts on the moving support plate 5. Air is introduced through the filter screen 15 at the input end of the blower 14 and blown through the blower side box 13 for cooling. Then, the output end of the first motor 21 drives one of the adjusting screws 3 and the first pulley 20 to move in the opposite direction to complete the unloading and feeding of another injection molded part.
