Description

Technical Field

[0001] This utility model relates to the field of precision injection molding automated equipment technology, and in particular to an automated production and removal device for liquid molding of optical silicone parts. Background Technology

[0002] Optical silicone components (such as lens seals, light guides, and condensers) have extremely high requirements for dimensional accuracy, surface quality, and consistency. Their manufacturing process involves multiple stages, including injection molding, sprue treatment, component removal, and subsequent placement. Currently, the level of automation in this field still faces many bottlenecks, hindering further improvements in production efficiency and product yield.

[0003] Traditional production methods typically employ a single injection molding machine in conjunction with manual or semi-automatic robotic arms for part removal and sprue treatment. Operators must manually or with mechanical assistance remove parts after mold opening and then transfer them to an independent workstation for sprue trimming. This method is not only inefficient and costly in terms of labor, but manual intervention is also highly susceptible to contamination, scratches, or dimensional deviations, making it difficult to meet the stringent cleanliness and precision requirements of optical components.

[0004] In the sprue treatment process, although some companies have developed dedicated shearing devices, existing technologies, such as the Chinese authorization announcement number CN221756753U, authorized on September 24, 2024, provide a self-retrieving and self-cutting sprue device for injection molded products. This device includes: a processing box with a glass-sealed door at its front end; openings on both sides of the processing box; conveyor belts on both sides of the processing box; and extensions of the two conveyor belts passing through the two openings. The processing box contains a material-retrieving component, a shearing component at the top center, and a support component at the bottom center. By setting up the processing box, shearing is performed inside. A suction pump and a debris collection box are also included to facilitate the handling of debris generated during shearing. The use of conveyor belts and the material-retrieving component improves automation. There is also Chinese authorization announcement number CN222858652U, with an authorization announcement date of May 13, 2025, which discloses a cutting device for automotive lamp inserts, belonging to the field of automation equipment technology. It includes an automatic control box and a vibratory feeder control box, which are fixedly connected. A fixed plate is fixedly connected to both the automatic control box and the vibratory feeder control box. The fixed plate is equipped with a feeding mechanism, a product embedding mechanism, a first cutting mechanism, and a second cutting mechanism. The embedding and cutting of automotive lamp inserts are directly processed on this equipment, realizing automatic forming of the embedding and cutting of automotive lamp inserts, thereby improving work efficiency. Furthermore, the feeding mechanism and the product embedding mechanism embed the automotive lamp inserts, allowing two different automotive lamp products to be embedded and combined. The first and second cutting mechanisms process two different automotive lamp products simultaneously, allowing different automotive lamp products to be processed at the same time, further improving work efficiency. The equipment disclosed in the above-mentioned prior art is mostly used as an independent unit, requiring additional handling machinery and positioning mechanisms. This results in dispersed processes, long cycle times, and increased equipment footprint and coordination difficulties. Some solutions employ ultrasonic cutting technology to achieve burr-free cutting, but its efficient coordination and integrated application with the injection molding cycle still need optimization.

[0005] Regarding part handling and transfer, while there are existing dual-station injection molds (such as automatic insert replacement mechanisms) that achieve alternating production through mold rotation, and dual-station transfer robot patents, such as Chinese Patent Announcement No. CN223001015U, authorized on June 20, 2025, which discloses an automatic sprue-cutting device for a headgear, including a sprue-cutting mechanism comprising a horizontal fixed plate and a vertical fixed plate fixedly connected, a top fixed plate fixedly connected to the top of the vertical fixed plate, scissors at both ends of the vertical fixed plate, and a push cylinder fixedly connected to the bottom side wall, positioning pins inserted at both ends of the horizontal fixed plate, and a rotating suction cup mechanism including a robot jig that moves the sprue to the scissors, with the push cylinder pushing the scissors to cut off the sprue, these technologies mostly focus on internal mold actions or single pick-and-place functions, failing to seamlessly integrate multiple processes such as injection molding, shearing, and part placement into a continuous automated system. Existing robotic arms still face challenges in grasping stability and positioning accuracy when dealing with the characteristics of silicone parts that are easily deformed and stick to the mold.

[0006] Furthermore, current equipment generally lacks coordinated control over the entire production process. For example, there are no solutions yet to achieve efficient and reliable closed-loop management for issues such as real-time removal of sprue material, precise positioning of components, and timing synchronization of actions at dual workstations. This results in waiting time, accumulated errors, and potential quality risks during production.

[0007] Therefore, there is an urgent need to develop a highly integrated, fully automated device that can solve the above technical problems. Utility Model Content

Detailed Implementation

[0029] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with specific embodiments and accompanying drawings.

[0030] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] Please refer to Figure 1-7As shown, this utility model provides an automated production and removal device for liquid molding of optical silicone parts, including an injection molding machine frame 10, a three-plate mold assembly 11, a first material handling component 15, a second material handling component 16, a sprue handling component 14, a central control system, a servo-driven translation mechanism 29, and a control screen 17. The three-plate mold assembly 11, the first material handling component 15, the second material handling component 16, the sprue handling component 14, the servo-driven translation mechanism 29, and the control screen 17 are all connected to the central control system. The ball screw slides used in this embodiment are all high-precision ball screw slides with a precision of C3 grade or above.

[0032] The three-plate mold assembly 11 is installed in the middle of the injection molding machine frame 10. A truss 12 is installed on the injection molding machine frame 10. The first material handling component 15 and the second material handling component 16 are respectively installed on the truss 12 and located on opposite sides of the three-plate mold assembly 11. The sprue handling component 14 is installed on the truss on the side closer to the first material handling component 15. The control screen 17 is installed on the truss 12 on the side closer to the second material handling component 16. This embodiment can integrate the injection molding, sprue shearing, part handling and part placement processes of optical silicone parts into one, and achieve overlapping production cycles through dual-station alternating operation, thereby greatly improving production efficiency, product consistency and automation level.

[0033] A servo-driven translation mechanism 29, adapted to the first material handling assembly 15 and the second material handling assembly 16, is mounted above the injection molding machine frame 10 along its length. This is a high-precision multi-axis motion module, typically with three axes (XYZ) or at least including the XY axis, and its slide is programmable to achieve precise linear motion. This mechanism is the foundation for the execution of the entire automated material handling system.

[0034] A first blister pack 23 is installed on the side of the injection molding machine frame 10 corresponding to the first material handling component 15; a second blister pack 18 is installed on the side of the injection molding machine frame 10 corresponding to the second material handling component 16.

[0035] A first material handling component control box 22 is provided on the side of the injection molding machine frame 10 corresponding to the first blister box 23; a second material handling component control box 20 is provided on the side of the injection molding machine frame 10 corresponding to the second blister box 18; both the first material handling component control box 22 and the second material handling component control box 20 are connected to the main control system.

[0036] The injection molding machine fixed template 41 is installed on the truss 12 at the position corresponding to the three-plate mold assembly 11. The three-plate mold assembly 11 includes, from top to bottom, a fixed mold fixing plate 26, an intermediate runner plate 25, a first moving template 19, and a second moving template 21. The fixed mold fixing plate 26 is fixedly connected to the injection molding machine fixed template 41 and is the injection end of the molten plastic. It is in contact with the nozzle of the injection molding machine and is rigidly fixedly connected to the upper injection molding machine fixed template 41 by bolts or other means. This plate remains stationary throughout the entire working process.

[0037] The intermediate runner plate 25 is fixedly connected to the moving platen of the injection molding machine; this is the mold's "runner ejector plate" or "stripper plate." It functions similarly to the runner ejector plate in a traditional three-plate mold, but its connection method differs. It is fixedly connected to the moving platen of the injection molding machine. Its mold opening and closing motion is directly driven by the power of the injection molding machine, resulting in high precision and powerful operation.

[0038] The first moving template 19 and the second moving template 21 are respectively mounted on the slide of the servo-driven translation mechanism 29. The first moving template 19 and the second moving template 21 are equipped with the product molding cores, which are not directly driven by the injection molding machine, but are independently mounted on the slide of the servo-driven translation mechanism 29.

[0039] In actual operation, the injection molding machine performs a mold closing action, pushing its moving platen to move. The moving platen drives the intermediate runner plate 25, which is fixed to it, to move downwards. At the same time, the servo-driven translation mechanism 29 controls the displacement of the first moving platen 19 or the second moving platen 21, ultimately making them tightly fit with the intermediate runner plate 25 and the fixed mold plate 26, forming a complete mold cavity. Molten plastic is injected through the fixed mold plate 26 and fills the cavity through the point gate on the intermediate runner plate 25. The pressure holding and cooling processes are no different from those of traditional molds. At the end of the injection cycle, the injection molding machine begins to open the mold, driving its moving platen and the intermediate runner plate 25 to retract, separating from the fixed mold plate 26 and the first moving platen 19 or the second moving platen 21. The sprue and main runner sprue are retained in the runner of the intermediate runner plate 25, while the molded product remains on the core of the first moving platen 19 or the second moving platen 21. At this time, the servo-driven translation mechanism 29 and the first moving platen 19 or the second moving platen 21 on it remain stationary. After the sprue pick-up and drop assembly 14 removes the sprue material from the flow channel of the intermediate flow channel plate 25, the servo-driven translation mechanism 29 moves the first moving template 19 or the second moving template 21 to the position of the pick-up assembly on the corresponding side to prepare for the pick-up action.

[0040] The servo-driven translation mechanism 29 includes two servo motors, a linear guide rail B, a first ball screw slide 24, and a second ball screw slide 28. The two servo motors are servo motor A adapted to the first ball screw slide 24 and servo motor B adapted to the second ball screw slide 28. The first ball screw slide 24 is mounted on the linear guide rail B and its position is adapted to the first material handling component 15. The second ball screw slide 28 is mounted on the linear guide rail B and its position is adapted to the second material handling component 16. The linear guide rail B is equipped with servo motors connected to the first ball screw slide 24 and the second ball screw slide 28, respectively. The first moving template 19 is fixedly mounted on the first ball screw slide 24, and the second moving template 21 is fixedly mounted on the second ball screw slide 28. The control system can independently program and control the two servo motors, enabling the first moving template 19 and the second moving template 21 to achieve synchronous, asynchronous, or complex motion trajectories in a specific sequence.

[0041] The sprue handling assembly 14 includes a servo motor, an electric push rod 40, a first servo electric gripper 38, a vision positioning system, and a linear guide rail A27. The linear guide rail A27 is mounted on a truss via a fixed base. The electric push rod 40 is mounted on the linear guide rail A27. The servo motor is connected to the electric push rod 40, and the power output end of the electric push rod 40 is connected to the first servo electric gripper 38. The vision positioning system is correspondingly mounted on the mounting bracket 39 of the first servo electric gripper 38. The first servo electric gripper is equipped with a pressure sensor.

[0042] Both the first material handling assembly 15 and the second material handling assembly 16 include a third ball screw slide 13, a mounting base 45, a first lifting drive motor 30, a motor mounting base 31, a second lifting drive motor 32, a second servo electric gripper 35, and a fourth ball screw slide 42. The fourth ball screw slide 42 is fixedly mounted on the truss, and the third ball screw slide 13 is fixedly mounted on the slide of the fourth ball screw slide 42. The displacement direction of the third ball screw slide 13 and the displacement direction of the fourth ball screw slide 42 are perpendicular to each other. The third ball screw slide 13 is fixedly mounted on the truss, and the mounting base 45 is fixedly connected to the slide of the third ball screw slide 13. The first lifting drive motor 30 is fixedly mounted on the lower part of the mounting base 45, and the power output end of the first lifting drive motor 30 is connected to the motor mounting base 31. The second lifting drive motor 32 is fixedly mounted on the lower surface of the motor mounting base 31, and the power output end of the second lifting drive motor 32 is connected to the second servo electric gripper 35.

[0043] The lower part of the motor mounting base 31 is connected to a suction nozzle mounting plate 37 via a connecting rod. Several rectangularly arranged negative pressure suction nozzles 36 are mounted on the suction nozzle mounting plate 37. When the material handling assembly moves directly above the product and descends, causing the end face of the suction nozzle 36 to contact the product surface, the control system issues a command to start the vacuum generator. The vacuum generator rapidly draws air from the sealed cavity through the suction nozzles 36, lowering the internal pressure below atmospheric pressure. This pressure difference between atmospheric pressure and the internal pressure of the cavity firmly adheres the product to the suction nozzles. Once the product is transported to the target location, the control system commands the vacuum generator to shut off and switches the solenoid valve to blow positive pressure gas into the pipeline, instantly eliminating the negative pressure inside the suction nozzles, restoring pressure balance, and releasing the product.

[0044] Multiple air nozzles 34 are mounted on opposite sides of the motor mounting base 31 via positioning seats 33; a second servo electric gripper 35 passes through the suction nozzle mounting plate 37 and extends below it; a third ball screw slide 13 is connected to the servo motor. The control system commands the solenoid valve on the air blowing circuit to open, and compressed gas is ejected at high speed through the air nozzles 34, forming one or more concentrated airflows. The function of this airflow is to disperse and remove any dust, debris, or sprue material that may remain in the mold cavity, ensuring the cleanliness of the cavity during the next injection molding, thereby guaranteeing the molding quality of subsequent products and avoiding the production of defective products due to contamination.

[0045] Although both the negative pressure suction nozzle 36 and the air blowing nozzle 34 are pneumatic components, they have opposite functions. The air circuit system is independently controlled, and under the program scheduling of the control system, they move sequentially in different process cycles to work together to complete high-standard automated production tasks.

[0046] The first lifting drive motor 30 is connected to the servo motor; the negative pressure suction nozzle is connected to the vacuum generator through a vacuum pipe; the air blowing nozzle is connected to the air compressor through a solenoid valve and an air pipe.

[0047] The operation steps of this embodiment are as follows:

[0048] Preparation phase: The main control system is started via control panel 17, and production parameters are set. The vacuum generator and air compressor are started, providing air supply to the negative pressure suction nozzle 36 and the air blowing nozzle 34. The vision positioning system performs self-calibration.

[0049] Injection Molding and Mold Opening: After the injection molding machine completes the injection molding of the optical silicone part, the mold is opened. The intermediate runner plate 25 moves with the moving platen of the injection molding machine and separates from the fixed mold plate 26. The servo motor of the sprue pick-and-place assembly 14 drives the electric push rod 40, which moves the first servo electric gripper 38 along the linear guide rail A27 to the top of the mold. The vision positioning system identifies the sprue position, guides the gripper to accurately pick up the runner (sprue), and places it in the designated collection point.

[0050] The servo-driven translation mechanism 29 is activated, driving the first moving template 19 to move along the linear guide rail B to the preset picking position corresponding to the first picking component.

[0051] Product removal and placement:

[0052] The first material handling component picks up the material: the third ball screw slide 13 of the first material handling component 15 drives it to move as a whole above the first moving template 19. The second lifting drive motor 32 drives the second servo electric gripper 35 to descend. The second servo electric gripper 35 clamps the residual sprue in the mold cavity of the first moving template 19 and places it in the designated position before resetting above the first moving template 19. Subsequently, the first lifting drive motor 30 drives the suction nozzle mounting plate 37 to descend, the negative pressure suction nozzle 36 picks up the product, and the air blowing nozzle 34 blows air to assist separation. After the material handling is completed, the first material handling component moves above the first blister box 23, the negative pressure is released, and the product is neatly placed into the blister box.

[0053] Cleaning of moving template: Subsequently, the first material handling component 15 moves again above the first moving template 19, and the air nozzle 34 operates again to clean the mold cavity of the first moving template 19.

[0054] After the first moving template 19 moves along the linear guide B to the preset pick-up position corresponding to the first pick-up component, the second moving template 21 moves to the position of the middle runner plate 25 to prepare for the next injection molding action. After the injection molding machine completes the injection molding of the optical silicone part, it opens the mold again. The second pick-up component 16 performs a similar operation at the same time to pick up the product on the second moving template 21.

[0055] Cycle and Monitoring: All components reset, the mold closes, and the next injection cycle begins. The central control system monitors the entire process's operating status, cycle time, and equipment parameters in real time.

[0056] The above-described embodiments are merely one implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
