Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, and particularly relates to an automatic device for removing plastic injection points. Background Technique

[0002] With the market demand, the appearance requirements of plastic products are getting higher and higher. The requirements for the injection points of plastic parts are flat, without excessive glue. Excessive glue will generate burrs or protrusions, thus affecting the overall smoothness and shape, resulting in a decline in quality or the appearance of defective products. However, products such as mouse shells produced by injection molding must have injection points, which must be faced and removed. It only depends on how to achieve the removal operation of the injection points to meet both the quality requirements and the production efficiency requirements.

[0003] The traditional method for removing the injection points of plastic parts is to let workers use blades or files to correct the plastic injection points. However, the work efficiency of manually removing the injection points of plastic parts is relatively low, and it is difficult to have high consistency in manual operation, which may result in different qualities. Moreover, on large production lines, products are continuously output, the labor intensity of workers is relatively large, and workers may easily cut their hands when using blades or files, posing a safety hazard.

[0004] Therefore, we design an automatic device for removing plastic injection points here. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic device for removing plastic injection points in view of the deficiencies of the prior art, so as to solve the problems raised in the background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer toFigure 1 - Figure 2 , this embodiment relates to an automatic device for removing plastic injection points, including a base 1, a housing 2 and a profiling fixture 3. Among them, the housing 2 and the profiling fixture 3 are installed on the top of the base 1, and the profiling fixture 3 is located inside the housing 2. The profiling fixture 3 is used to position the plastic part 18. On the profiling fixture 3, two plastic parts 18 can be placed simultaneously at one time. Two backrests 4 are fixedly installed on the front inside of the housing 2. A double-axis cylinder 5 is installed on the upper part of the front of the backrest 4, and a cylinder lowering height magnetic inductor 17 is installed on the double-axis cylinder 5. A guide rail 6 perpendicular to the base 1 is installed on the lower part of the front of the backrest 4. A mounting frame 7 is slidably installed on the guide rail 6. The output rod of the double-axis cylinder 5 is connected to the mounting frame 7. A servo motor 8 and a buffer 9 are installed on the mounting frame 7. The output shaft of the servo motor 8 and the output end of the buffer 9 both face downward and are perpendicular to the base 1. A two-edge flat-bottom milling cutter 10 is installed on the output shaft of the servo motor 8.

[0020] When the plastic part 18 is placed on the profiling fixture 3, the two-edge flat-bottom milling cutter 10 is exactly above the injection point of the plastic part 18, and the servo motor 8 can drive the two-edge flat-bottom milling cutter 10 to rotate at high speed. The double-axis cylinder 5 can control the mounting frame 7 to translate downward along the guide rail 6, so that the mounting frame 7 drives the servo motor 8 and the buffer 9 to translate downward together, thereby controlling the feed of the two-edge flat-bottom milling cutter 10, and enabling the two-edge flat-bottom milling cutter 10 to remove the injection on the plastic part 18. The bottom of the output end of the buffer 9 should be slightly lower than the bottom of the two-edge flat-bottom milling cutter 10. The buffer 9 plays a role in pressing the plastic part 18, and at the same time, the buffer 9 can also prevent the plastic part 18 from being lifted when the milling cutter returns.

[0021] A start switch 11, an NG / OK indicator light 12, an intelligent controller 13 and an emergency switch 14 are also installed on the front of the base 1. There are two start switches 11, which are respectively arranged on the left and right sides of the front of the base 1. The two start switches 11 need to be pressed simultaneously to start the device, so as to prevent the device from being accidentally started.

[0022] Before using the device, set the feed amount of the output rod of the double-axis cylinder 5 on the intelligent controller 13. After the output rod extends to the preset feed amount, it will automatically reset. The intelligent controller 13 can also count the number of good products and defective products of the plastic part 18 to make the number of inlets and the number of operations consistent. The intelligent controller 13 here is a commonly used component in the market, and its basic set functions are applied, which belongs to the conventional application of the prior art.

[0023] On the top of the left and right sides of the base 1, safety light curtains 15 are symmetrically installed through brackets. The safety light curtains 15 are located in front of the housing 2 and are automatically turned on when the device performs the operation of correcting the glue injection point. When the infrared light beam of the light curtain is blocked by an external object, the device automatically stops working. The safety light curtains 15 play a role in protecting workers and reducing the possibility of workers being injured in the working environment.

[0024] An air source filter 16 is installed outside the housing 2. The air outlet of the air source filter 16 is connected to the direction control valve of the double-axis cylinder 5 through a pipeline. The compressor for supplying air to the double-axis cylinder 5 is connected to the air inlet of the air source filter 16. The function of the air source filter 16 is to filter the air entering the cylinder and prevent impurities in the air from affecting the accuracy and service life of the double-axis cylinder 5.

[0025] When the plastic glue injection point automatic removal device of the present utility model is in use, the plastic part 18 with a glue injection point is placed on the profiling fixture 3. Press the start switch 11 with both hands, and the servo motor 8 drives the two-edge flat-bottom milling cutter 10 to rotate. Manually turn on the double-axis cylinder 5, and the double-axis cylinder 5 controls the mounting frame 7 to move downward along the guide rail 6, so that the mounting frame 7 drives the servo motor 8, the buffer 9 and the two-edge flat-bottom milling cutter 10 to descend. The buffer 9 first presses the plastic part 18, and then the two-edge flat-bottom milling cutter 10 corrects the glue injection point on the plastic part 18. When the light of the magnetic inductor 17 for the descending height of the cylinder is on, the correction height reaches the preset position, and the NG / OK indicator light 12 shows a green light, indicating a good product; when the light of the magnetic inductor 17 for the descending height of the cylinder is not on and the NG / OK indicator light 12 shows a red light, this product is not a good product.

[0026] After the output rod of the double-axis cylinder 5 reaches the preset position and resets, it drives the servo motor 8, the buffer 9 and the two-edge flat-bottom milling cutter 10 back to the original position. After the device is fully reset, the corrected plastic part 18 is taken manually.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
