Description

Technical Field

[0001] This utility model relates to the technical field of tray injection molding devices, specifically a tray injection molding device with automatic calibration function. Background Technology

[0002] In the process of tray injection molding, in order to ensure product quality and avoid flash (overflow) during injection molding, traditional tray injection molding equipment usually designs the mold cavity as a splicing structure. This structure forms a complete mold cavity by splicing multiple modules. After injection molding, the mold cavity needs to be unfolded first, and then the molded tray workpiece is ejected, thereby reducing the generation of flash and ensuring the dimensional accuracy of the tray.

[0003] However, traditional mold cavity splicing modules are each equipped with an independent cylinder drive source. Each cylinder requires individual parameter setting and motion control. In actual production, operators need to use complex programming and debugging to accurately set parameters such as start time, extension stroke, and pressure of each cylinder to ensure the coordination of mold cavity splicing and unfolding actions. Once a cylinder malfunctions or the parameter setting is deviated, it will lead to problems such as incomplete mold cavity splicing and asynchronous unfolding, which will affect the molding quality of the tray and produce defects such as dimensional errors and surface defects. In order to solve the above problems, the inventors have proposed a tray injection molding device with automatic calibration function. Utility Model Content

[0004] In order to solve the problem of stable and consistent mold opening in tray injection molding devices, the purpose of this utility model is to provide a tray injection molding device with automatic calibration function.

[0005] To solve the above technical problems, this utility model adopts the following technical solution: a tray injection molding device with automatic calibration function, including a mold body, three mold cavity assemblies are arranged on one side of the mold body, the three mold cavity assemblies are arranged perpendicularly in pairs, two symmetrically distributed guide rods are fixedly connected to each of the three sides of the mold body, two symmetrically distributed guide plates are fixedly connected to the side of each mold cavity assembly away from the mold body, the guide plates are slidably engaged with the outside of the corresponding guide rods, and a movable plate is fixedly connected to the side of the mold body away from the mold cavity assemblies, the movable plate being connected to the mold body... A driving assembly is provided, comprising a movable frame that is slidably engaged with the outside of the mold body. Connecting rods are rotatably connected to the sides of the movable frame and corresponding positions of the mold cavity assembly. A fixing block is fixedly connected to one side of the mold cavity assembly, located between two guide plates. The end of the connecting rod away from the movable frame is rotatably connected to the fixing block. A limit block is fixedly connected to the end of each guide rod away from the mold cavity assembly. A displacement sensor is installed on the limit block. A hydraulic rod is fixedly installed on the side of the movable plate away from the mold body, and the piston rod of the hydraulic rod is fixedly connected to the movable frame.

[0006] Preferably, two mounting plates are provided on both sides of the mold body, and guide rods are fixedly connected between the four corners of the two mounting plates. The movable plate is slidably engaged between the outer sides of the guide rods.

[0007] Preferably, a threaded rod is rotatably connected between the bottoms of the two mounting plates, the movable plate is threaded to the outside of the threaded rod, a servo motor is fixedly mounted on one side of the mounting plate, and the drive end of the servo motor is fixedly connected to the threaded rod.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. By extending and retracting the hydraulic piston rod, the moving frame is pushed to move laterally and reciprocally along the outer side of the mold body. At the same time, the end of the connecting rod connected to the moving frame moves synchronously. The other end of the connecting rod is guided by the fixed block, which pushes the fixed block to move horizontally and linearly. This opens or closes the three mold cavity components at the same time, thus ensuring the consistency of the displacement of the mold cavity components. This avoids the problem of traditional mold cavity splicing modules each having an independent cylinder drive source. Each cylinder needs to be set with parameters and controlled by itself. If a cylinder fails or the parameter setting is deviated, it will lead to problems such as incomplete mold cavity splicing and asynchronous unfolding.

[0010] 2. The servo motor drives the threaded rod to rotate, which in turn drives the moving plate to move laterally along the outside of the threaded rod. The guide rod 2 guides the movement of the moving plate, improving the stability of the mold body during movement and avoiding deviations during mold closing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Example: Figure 1-4 As shown, this utility model provides a tray injection molding device with automatic calibration function, including a mold body 1. Three mold cavity components 2 are arranged on one side of the mold body 1. The three mold cavity components 2 are arranged vertically in pairs. Two symmetrically distributed guide rods 5 are fixedly connected to three sides of the mold body 1. Two symmetrically distributed guide plates 4 are fixedly connected to the side of the mold cavity components 2 away from the mold body 1. The guide plates 4 are slidably engaged with the outside of the corresponding guide rods 5. A moving plate 12 is fixedly connected to the side of the mold body 1 away from the mold cavity components 2. A driving component is arranged between the moving plate 12 and the mold body 1.

[0019] The driving component includes a movable frame 6, which is slidably engaged on the outside of the mold body 1. The side of the movable frame 6 and the corresponding position of the mold cavity assembly 2 are rotatably connected to a connecting rod 7. The mold cavity assembly 2 is fixedly connected to a fixing block 3 on one side and between the two guide plates 4. The end of the connecting rod 7 away from the movable frame 6 is rotatably connected to the fixing block 3.

[0020] By adopting the above technical solution, when the moving frame 6 slides along the outside of the mold body 1, it drives the end of the connecting rod 7 connected to the moving frame 6 to move synchronously. The other end of the connecting rod 7 is guided by the fixing block 3, and the fixing block 3 is pushed to move horizontally in a straight line, thereby opening or closing the three mold cavity components 2 at the same time, thus ensuring the consistency of the displacement of the mold cavity components 2.

[0021] The end of the guide rod 5 away from the mold cavity assembly 2 is fixedly connected to a limit block 9, and a displacement sensor is installed on the limit block 9.

[0022] By adopting the above technical solution, when the mold cavity assembly 2 opens and the guide plate 4 contacts the limiting block 9, the limiting block 9 is used to limit the movement of the mold cavity assembly 2, and the displacement sensor is used to lock the position of the guide plate 4, thereby ensuring that the position of the mold cavity assembly 2 is consistent each time.

[0023] Two mounting plates 10 are provided on both sides of the mold body 1. Guide rods 11 are fixedly connected between the four corners of the two mounting plates 10. The movable plate 12 is slidably engaged between the outer sides of the guide rods 11.

[0024] By adopting the above technical solution and setting the guide rod 11, the movement of the moving plate 12 can be guided, thereby improving the stability of the mold body 1 when it moves and avoiding deviations when the mold is closed.

[0025] A threaded rod 13 is rotatably connected between the bottoms of the two mounting plates 10. A movable plate 12 is threadedly connected to the outside of the threaded rod 13. A servo motor 14 is fixedly mounted on one side of the mounting plate 10, and the drive end of the servo motor 14 is fixedly connected to the threaded rod 13.

[0026] By adopting the above technical solution, the servo motor 14 drives the threaded rod 13 to rotate, and at the same time drives the moving plate 12 to move laterally along the outside of the threaded rod 13, thereby performing mold opening and closing operations.

[0027] A hydraulic rod 8 is fixedly installed on the side of the movable plate 12 away from the mold body 1, and the piston rod of the hydraulic rod 8 is fixedly connected to the movable frame 6.

[0028] By adopting the above technical solution, the extension and retraction of the piston rod of the hydraulic rod 8 pushes the moving frame 6 to move laterally and reciprocally along the outside of the mold body 1, thereby realizing the driving of opening and closing between the mold cavity components 2.

[0029] Working principle: When the tray is injection molded, the servo motor 14 drives the threaded rod 13 to rotate, and at the same time drives the moving plate 12 to move laterally along the outside of the threaded rod 13. The guide rod 11 guides the movement of the moving plate 12, improving the stability of the mold body 1 when it moves and avoiding deviations when the mold is closed.

[0030] When the mold is opened, the extension of the hydraulic rod 8 pushes the moving frame 6 to slide along the outside of the mold body 1, and drives the end of the connecting rod 7 connected to the moving frame 6 to move synchronously. The cooperation between the guide rod 5 and the guide plate 4 guides the movement of the mold cavity assembly 2, and at the same time unfolds the three mold cavity assemblies 2. The displacement of the mold cavity assembly 2 is limited by the limiting block 9, so that the position of the ear mold cavity assembly 2 moves in the same way each time, thereby ensuring the stability of the equipment during operation.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
