Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically a vertical three-station low-table injection molding machine. Background Technology

[0002] Injection molding machines are key pieces of equipment used to mold thermoplastic or thermosetting plastics into plastic products. Their core functions include: heating the plastic to a molten state; applying high pressure to inject the molten material into the mold cavity; and then demolding the product after cooling and solidification. They can be vertical, horizontal, or fully electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] Existing vertical injection molding machine worktables include standard tabletops, discs, single-slide plates, and double-slide plates. However, a standard tabletop has only one station, and time is required to pick up and put down parts after each mold opening and closing. A single-slide plate can extend the mold to the operator's front, but only one station can be operated at a time. A double-slide plate has two stations on the left and right, but they do not slide out from the same position. A disc usually only has two stations, so its efficiency is low. On the other hand, it is difficult to clean the impurities remaining on the surface of a conventional injection molding machine disc, which can easily cause adhesion and blockage inside the mold cavity. Utility Model Content

This invention makes product handling more efficient, is equipped with a robotic arm suitable for large-scale, high-volume production, and can periodically scrape and clean the three-station disc through a cleaning mechanism, thereby cleaning up residual waste on the disc surface and achieving a self-cleaning function. In conjunction with the central air inflation mechanism, it can specifically push out the residue accumulated in the cavity of the three-station disc surface during cleaning.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vertical three-station low-worktable injection molding machine, comprising an injection molding machine body, the injection molding machine body including a worktable, a three-station disc, ejector pin chambers, and a cleaning mechanism, the three-station disc being mounted on the surface of the worktable, the front end of the worktable having a triangular structure, two ejector pin chambers being provided at the bottom of the worktable, the cleaning mechanism being mounted above the three-station disc, and an inflation mechanism being provided in the middle of the cleaning mechanism, the bottom of the cleaning mechanism being used to press against the surface of the three-station disc.

[0006] Furthermore, the surface of the three-station disc is used to install three sets of molds, and each station is used to realize the insert, injection, and part removal processes. Four start and emergency stop buttons are configured at the edge of the worktable, and the top of the cleaning mechanism is fixed to the frame of the injection molding machine.

[0007] Furthermore, the cleaning mechanism includes an inflation mechanism, a fixed plate, and a lifting plate. A transmission frame is welded in the middle of the lifting plate, a pressure platform is integrally formed at the rear end of the transmission frame, and a scraper is integrally formed at the bottom of the lifting plate.

[0008] Furthermore, an extension plate is integrally formed on one middle side of the fixed plate, a guide post is welded to the bottom of the fixed plate, a lifting sleeve is welded to the top of the lifting plate, and the bottom of the guide post is embedded inside the lifting sleeve.

[0009] Furthermore, the guide columns and lifting sleeves are symmetrically arranged on both sides of the transmission frame, and the bottom of the scraper is used to press against the surface of the three-position disc.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1 to 5 This utility model provides the following technical solution: a vertical three-station low-worktable injection molding machine, including an injection molding machine body, the injection molding machine body including a worktable 1, a three-station disc 2, an ejector pin chamber 3, and a cleaning mechanism 4. The three-station disc 2 is installed on the surface of the worktable 1. The front end of the worktable 1 has a triangular structure. Two ejector pin chambers 3 are provided at the bottom of the worktable 1. The cleaning mechanism 4 is installed above the three-station disc 2, and an inflation mechanism 7 is provided in the middle of the cleaning mechanism 4. The bottom of the cleaning mechanism 4 is used to press against the surface of the three-station disc 2. The surface of the three-station disc 2 is used to install three sets of molds, and each station is used to realize the insertion, injection, and part removal processes. Four start and emergency stop buttons are provided at the edge of the worktable 1. The top of the cleaning mechanism 4 is fixed to the frame of the injection molding machine. This injection molding machine realizes injection molding processing through three stations on the surface of the three-station disc 2.

[0025] This invention features three sets of molds mounted on a disc, with three workstations for inserting, injection, and unloading. The front half of the frame is designed as a triangle, providing more operating space and better suited for automated equipment. This makes product handling more efficient, and the inclusion of a robotic arm makes it suitable for large-scale, high-volume production. The workstations are switched by rotating the three-station disc 2, thereby realizing the subsequent inserting, injection, and unloading processes. The top cleaning mechanism 4 is used to scrape and clean the surface of the three-station disc 2 and the interior of the mold cavity within each workstation.

[0026] In this embodiment, the cleaning mechanism 4 includes an inflation mechanism 7, a fixed plate 5, and a lifting plate 6. A transmission frame 15 is welded to the middle of the lifting plate 6, and a pressure platform 17 is integrally formed at the rear end of the transmission frame 15. A scraper 14 is integrally formed at the bottom of the lifting plate 6. An extension plate 18 is integrally formed on one side of the middle of the fixed plate 5, and a guide post 19 is welded to the bottom of the fixed plate 5. A lifting sleeve 16 is welded to the top of the lifting plate 6, and the bottom of the guide post 19 is embedded inside the lifting sleeve 16. The guide post 19 and the lifting sleeve 16 are symmetrically arranged on both sides of the transmission frame 15. The bottom of the scraper 14 is used to press against the surface of the three-position disc 2. The cleaning mechanism 4 is installed on the surface of the three-position disc 2. The cleaning mechanism 4 can periodically scrape and clean the three-position disc 2, thereby cleaning the waste residue on the disc surface and realizing the self-cleaning function.

[0027] Specifically, after activating the inner electric lifting rod 8, the bottom lifting plate 6 and the inflation mechanism 7 will move down with the top fixed plate 5 as support, so that the bottom of the lifting plate 6 is pressed down on the surface of the three-station disc 2 by the scraper 14. At this time, the bottom of the inflation mechanism 7 is not embedded in the mold of the station. Continue to start the rotation of the three-station disc 2, and the scraper 14 can remove the residue adhering to the surface of the three-station disc 2. During this process, the telescopic sleeve moves down inside the guide column 19 until the scraping and cleaning is completed, and the three-station disc 2 rotates to the bottom of the mold cavity on the station, so that the subsequent cleaning process of the inner wall of the mold cavity can be carried out.

[0028] In this embodiment, the inflation mechanism 7 includes an electric lifting rod 8, a connecting rod 10, and a conical airbag 12. The top end of the electric lifting rod 8 is fixed to the bottom of the extension plate 18, and the bottom of the electric lifting rod 8 is screwed with the connecting rod 10. A spring 11 is sleeved on the surface of the connecting rod 10. The conical airbag 12 is attached to the bottom of the connecting rod 10, and a rubber ring 13 is attached to the top edge of the conical airbag 12. A protruding ring 20 is welded to the top of the connecting rod 10. An inflation pipe 9 is connected to the surface of the connecting rod 10. The connecting rod 10 passes downward through the surface of the pressure platform 17, and the two ends of the spring 11 are fixed to the surface of the pressure platform 17 and the bottom of the protruding ring 20, respectively. During the cleaning process, the lifting structure at the top provides downward pressure to the cleaning mechanism 4, thereby increasing the scraping cleaning force. It also works in conjunction with the inflation mechanism 7 in the middle to specifically push out the residue accumulated in the surface cavity of the three-position disc 2 during cleaning.

[0029] Specifically, after the scraping and cleaning is completed, the three-station disc 2 is rotated to the bottom of the mold cavity on the station and the inflation mechanism 7 is moved. At this time, the electric lifting rod 8 is extended while the three-station disc 2 remains fixed. The conical airbag 12 at the bottom of the insertion rod 10 can then be embedded into the mold cavity. With the help of an external air pump, high-pressure airflow can be injected into the insertion rod 10, causing the conical airbag 12 to expand. Finally, the rubber ring 13 at the top is pressed against the inner wall of the cavity. Then, the electric lifting rod 8 is started again, and the rubber ring 13 can be used to pull out the residue adhering to the inner wall, avoiding the situation where a small amount of residue falls into the cavity when the scraper 14 scrapes the surface of the three-station disc 2.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
