Description

Technical Field

[0001] The utility model relates to a design for removing injection molding waste, in particular to a residual material removing device for an injection molding system. Background Art

[0002] In recent years, injection molding technology has become extremely mature. It can not only quickly meet molding requirements, but also ensure that the overall appearance and appearance of the molded objects have good stability. However, whether using general injection molding materials or supercritical fluids that are widely used in injection molding and have physical foaming properties, after the injection molding is completed, excess injection molding materials will overflow from the injection hole of the molding mold. When the injection molding materials come into contact with external air, they will condense around the injection hole in the form of residual material. At this time, if the molding mold is demolded, the residual material outside the molding mold is larger than the injection hole, making demolding difficult. If the mold is forcibly removed, the finished product will be damaged. Therefore, some businesses will use manual processing to scrape off the excess material generated on the forming mold. However, when using manual processing, since the excess material varies in size, the scraping force and processing time cannot be effectively controlled. If stubborn or large excess material is encountered, the processing time is not only lengthy and the operation efficiency is low, but the forming mold will be damaged during the scraping process, and the excess material cannot be effectively scraped off completely, resulting in the finished product after demolding still needing to undergo another shaping process, which is not only time-consuming and labor-intensive, but also invisibly increases the processing cost and needs to be improved.

[0036] The foregoing and other technical contents, features and effects of the present invention will be clearly understood in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0037] See Figure 1 and Figure 2A comparative embodiment of the present invention is used on an injection molding system 3, which includes a conveying device 31, an injection molding device 32 arranged on the side of the conveying device 31, and a plurality of molding molds 33 arranged on the conveying device 31; wherein, each molding mold 33 corresponds to the injection molding device 32 under the conveyance of the conveying device 31, and the injection molding device 32 corresponds to the injection hole 331 of the molding mold 33 to inject the injection plastic, so that the injection plastic is injection-molded in the molding mold 33.

[0038] Continuing from the above, in this embodiment, a residual material removal device 4 is additionally provided on one side of the conveying device 31, and the residual material removal device 4 includes a collecting unit 41 and a removal unit 42; wherein, the collecting unit 41 has a main body 411, an actuating member 412 provided on the main body 411, and a collecting member 413 provided on the actuating member 412, and the collecting member 413 is linked with the actuating member 412 to move toward the edge of the forming mold 33 located on the conveying device 31, such as to abut against the edge or move away from the edge. In this embodiment, one side of the collecting member 413 has a guide plate 413a, and the other side is provided with a drop port 413b, and a collecting member 414 can be provided at the drop port 413b to collect the material coming out of the drop port 413b.

[0039] Continuing with the above, the removal unit 42 includes a track 421 extending outward from the main body 411 and located above the conveying device, a movable base 422 arranged on the track 421 for movement, a pusher 423 arranged on the movable base 422 for extending or retracting, and a remover 424 arranged on the pusher 423. The pusher 423 and the remover 424 are driven by the sliding of the movable base 422 on the track 421 to move correspondingly toward the main body 411. The remover 424 will move the molding die 33 located on the conveying device 31 when the pusher 423 extends or retracts, that is, when extending, it moves against the molding die 33 to remove the excess material a produced at the injection hole 331 of the molding die 33, and after removal, it moves away from the molding die 33 during the retraction action of the pusher 423. In particular, In this embodiment, the remover 424 is designed to have a removal member 424a and two pusher members 424b arranged on both sides of the removal member 424a (only one side is shown in the figure), that is, the removal member 424a first removes the residual material a, and the two pusher members 424b cooperate to block the residual material a that is about to fly to the side after removal, and push the residual material a when the movable seat 422 moves toward the main body 411. The aforementioned removal member 424a is in the form of scissors to shear and remove the residual material a on the molding mold 33, or in the form of a cutter (not shown in the figure) to cut and remove the residual material a on the molding mold 33. The setting form of the removal member 424a is illustrated by the example shown in the figure. At the same time, the conveying device 31, the injection molding device 32 and the residual material removal device 4 are connected to a control device (not shown in the figure) and are controlled by the control device.

[0040] See Figure 1 and Figure 2When the injection molding system 3 is about to perform an injection molding operation, the conveying speed of the conveying device 31 is set to match the injection time / speed of the injection molding device 32, and the driving mode of the excess material removal device 4 is also set synchronously. Therefore, when in use, the plurality of molding molds 33 are conveyed by the conveying device 31 to the injection molding operation position corresponding to the injection molding device 32. At this time, the injection molding device 32 will perform injection molding on each molding mold 33 one by one, so that the injected injection plastic is formed according to the molding mold 3. 3 is formed, and the molding die 33 that has completed the injection molding operation will continue to be transported by the conveyor 31 to the excess material removal operation position to correspond to the removal unit 42. At this time, the collecting member 413 will be linked with the actuating member 412 and move from the main body 411 to the molding die 33 located on the conveyor 31 until the guide plate 413a abuts against the edge of the molding die 33. The actuating member 412 will stop the linkage, and the remover 424 will be on the pusher. Driven by the pusher 423, it extends and moves toward the corresponding molding die 33 until the remover 424 touches the surface of the molding die 33, and the pusher 423 stops moving. At this time, the removal member 424a will remove the excess material a produced at the injection hole 331. When the removal member 424a is removing, the moving seat 422 will move on the track 421, that is, move on the track 421 toward the main body 411, so that the removal member 424a moves along with the moving seat 4 22 moves, and gradually removes the remaining material a on the injection hole 331 one by one. At this time, the remaining material a after being removed will be blocked and pushed by the two pushing members 424b, so that the two pushing members 424b move along with the movement of the moving seat 422 to push the remaining material a after being removed to the guide plate 413a, and when the moving seat 422 gradually approaches the main body 411, the remaining material a is pushed into the collecting member 413 along the movement of the moving seat 422, and enters the collecting member 414 through the blanking port 413b for collection, that is, Figure 3 shown.

[0041] Continuing with the above, when the collecting member 413 completes the collection of the remaining materials, it will move toward the main body 411 under the linkage of the actuating member 412, so that the collecting member 413 no longer presses against the edge of the forming mold 33, and at the same time, the remover 424 is also moved away from the forming mold 33 under the retraction action of the pusher 423, and when the pusher 423 is retracted, the moving seat 422 will also be driven, that is, it moves along the track 421 to the side away from the main body 411 until it drives the pusher 423 and the remover 424 to the initial position and then stops moving, that is, Figure 4 、 Figure 2As shown, the excess material a of the molding die 33 is removed. By repeating this operation, the excess material a generated on each molding die 33 can be effectively removed at one time. Not only is the process neat and uniform, but the effect is also good. In addition, the finished product formed in the molding die 33 can be quickly and effectively demolded during the subsequent demolding operation without the need for another whole-molding process, thereby significantly and effectively improving the production yield of the injection molding process.

[0042] See Figure 5 Another preferred embodiment of the present invention still includes the components described in the previous embodiment, especially in this embodiment, the removal unit 42 is provided with a shield 425 (indicated by an imaginary line in the figure) on the remover 424, and the shield 425 is set in a perspective form to utilize the setting of the shield 425 on the remover 424, so that the residual material a that is about to be sprayed out after being removed by the removal member 424a can be blocked between the shield 425 and the removal member 424a and the pushing member 424b and is pushed into the collecting member 413 during the stacking process of the two pushing members 424b and collected by the collecting member 414, thereby maintaining the cleanliness of the machine and the processing environment to reduce the convenience of subsequent cleaning operations.

[0043] To summarize the above, the present invention is a residual material removal device for an injection molding system. The device is provided with a collecting unit and a removing unit on the side of a conveying device, so that the collecting part of the collecting unit can move toward the molding die located on the conveying device under appropriate actuation. At the same time, the remover of the removing unit can also move toward the surface of the molding die during the extension or retraction action. Through the cooperation between the collecting unit and the removing unit, the residual material generated on the molding die after the injection molding operation is completed can be removed. Of course, a baffle can be provided on the remover to block and concentrate the removed residual material to prevent the residual material after removal from flying, and the removed residual material can be pushed into the collecting part for collection by movement. In this way, the residual material generated on the molding die can be quickly removed at one time, which not only improves the smoothness of subsequent demolding, but also effectively improves the processing production efficiency.

[0044] The above contents are only for describing the preferred embodiments of the present utility model and should not be used to limit the scope of implementation of the present utility model. That is, any simple equivalent changes and modifications made according to the scope of the patent application of the present utility model and the contents of the utility model specification should still fall within the scope of the present utility model patent.
