Description

Technical Field

[0001] This utility model belongs to the field of injection mold technology, specifically a stacked mold driving mold opening mechanism. Background Technology

[0002] In the mold manufacturing industry, the stacked mold drive mold opening mechanism can significantly improve production efficiency due to its multi-layer molding characteristics. It is widely used in plastic products, precision castings and other fields. The mechanism realizes the orderly separation of the upper mold plate, middle mold plate and lower mold plate through the drive system to complete the demolding process. Compared with traditional single-layer molds, it has significant advantages in saving costs and increasing production capacity.

[0003] However, existing stacked mold opening mechanisms have obvious defects in the positioning and monitoring links during the mold opening process. Most traditional mechanisms rely on simple mechanical limit structures, which make it difficult to control the movement trajectory of the template in real time and accurately. During the mold opening process, problems such as excessive template opening distance leading to offset and misalignment often occur, resulting in increased mold wear. Therefore, this utility model provides a stacked mold driving opening mechanism. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology and solve the problems raised in the background art.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: The stacked mold driving mold opening mechanism of this utility model includes an upper mold plate, a middle mold plate and a lower mold plate. The lower end of the middle mold plate is fixedly installed with a base, and one end of the base is fixedly installed with an installation column. A pushing mechanism is provided on the surface of the installation column, and an extension mechanism is provided on the top of the middle mold plate.

[0006] Preferably, multiple fixing blocks are evenly fixedly connected to the upper and lower ends of the middle template, a positioning rod is fixedly installed on the outer end of the fixing block, and the other end of the positioning rod passes through the surface of the upper template and is fixedly connected to the limiting block.

[0007] Preferably, the pushing mechanism includes a double-headed hydraulic cylinder, a piston rod, and a fixed frame. The double-headed hydraulic cylinder is fixedly installed on the surface at the center of the mounting column. The piston rod is slidably connected to both ends of the double-headed hydraulic cylinder. The fixed frame is fixedly connected to the inner end of the upper and lower templates corresponding to the position of the piston rod. The other end of the piston rod extends into the interior of the fixed frame.

[0008] Preferably, the piston rod has a threaded groove on its outer end surface, the fixing frame has an installation groove inside, a limiting plate is provided inside the installation groove, and the limiting plate is threadedly connected to the surface of the piston rod.

[0009] Preferably, the extension mechanism includes a mounting plate 1, a rotating shell 1, a connecting rod, and a rotating shell 2. A main shaft 1 is fixedly mounted between the two mounting plates 1. The rotating shell 1 is sleeved on the surface of the main shaft 1. The connecting rod is fixedly mounted on the surface of the rotating shell 1. The other end of the connecting rod is fixedly connected to the rotating shell 2. The rotating shell 2 is sleeved on the surface of the main shaft 2. Both ends of the main shaft 2 are fixedly connected to the mounting plate 2.

[0010] Preferably, an extension frame is fixedly installed at the center of the upper surface of the middle template, a vertical groove is provided at the center of the extension frame, a central column is fixedly installed inside the vertical groove, a slider is sleeved on the surface of the central column, and mounting plates one are fixedly installed at both ends of the slider. Mounting plates two are fixedly installed at the inner end of the upper half of the upper and lower templates, corresponding to the position of the extension frame.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The stacked mold driving mold opening mechanism of this utility model separates the upper and lower mold plates through the cooperation of the pushing mechanism and the extending mechanism. The double-headed hydraulic cylinder drives the upper and lower mold plates to separate horizontally, while the slider slides on the surface of the central column to form a linear motion. When the pushing mechanism opens the upper and lower molds outward, the mold opening status is observed according to the position of the slider, and then the hydraulic cylinder thrust is adjusted to effectively avoid the mold opening distance being too large, and significantly improve the demolding accuracy and mold stability.

[0013] 2. The stacked mold driving mold opening mechanism of this utility model uses the limiting block and the limiting plate to limit the movement of the slider on the surface of the central column. The two work together to prevent deviation during the mold opening process. The limiting block limits the maximum mold opening distance of the template to prevent the mechanism from extending too much. The limiting plate adjusts the piston rod stroke to ensure that the hydraulic drive works within a safe range. At the same time, the linear correspondence between the slider position and the mold opening stroke allows the operator to intuitively judge the mold opening status. Attached Figure Description

The limiting block 12 restricts the movement distance of the upper mold plate 1 and the lower mold plate 3.

[0023] Furthermore, multiple fixing blocks 10 are evenly fixedly connected to the upper and lower ends of the middle template 2. A positioning rod 11 is fixedly installed on the outer end of the fixing block 10. The other end of the positioning rod 11 passes through the surface of the upper template 1 and is fixedly connected to the limiting block 12. The fixing blocks 10 and the positioning rod 11 ensure that the upper and lower templates move accurately along a straight line. The limiting block 12 restricts the movement distance of the upper template 1 and the lower template 3.

[0024] Furthermore, the pushing mechanism includes a double-headed hydraulic cylinder 6, a piston rod 7, and a fixed frame 8. The double-headed hydraulic cylinder 6 is fixedly installed on the surface of the center of the mounting column 5. The piston rod 7 is slidably connected to both ends of the double-headed hydraulic cylinder 6. The fixed frame 8 is fixedly connected to the inner end of the upper template 1 and the lower template 3 corresponding to the position of the piston rod 7. The other end of the piston rod 7 extends into the interior of the fixed frame 8. The double-headed hydraulic cylinder 6 pushes the piston rod 7 to both ends, and the piston rod 7 pushes the upper template 1 and the lower template 3 on both sides to open the mold.

[0025] Furthermore, a threaded groove is provided on the outer end surface of the piston rod 7, and an installation groove is provided inside the fixing frame 8. A limiting plate 9 is provided inside the installation groove. The limiting plate 9 is threadedly connected to the surface of the piston rod 7. The limiting plate 9 is installed inside the fixing frame 8 with the piston rod 7, and the limiting plate 9 connects the piston rod 7 and the fixing frame 8.

[0026] Furthermore, the extension mechanism includes mounting plate 16, rotating shell 17, connecting rod 18, and rotating shell 2 19. Main shaft 1 is fixedly installed between the two mounting plates 16. Rotating shell 17 is sleeved on the surface of main shaft 1. Connecting rod 18 is fixedly installed on the surface of rotating shell 17. The other end of connecting rod 18 is fixedly connected to rotating shell 2 19. Rotating shell 2 19 is sleeved on the surface of main shaft 2. Both ends of main shaft 2 are fixedly connected to mounting plate 2 20. Main shaft 1 drives rotating shell 17 to move downward. One end of connecting rod 18 moves downward, and the other end of connecting rod 18 expands outward synchronously as the upper and lower templates separate.

[0027] Furthermore, an extension frame 13 is fixedly installed at the center of the upper surface of the middle template 2. A vertical groove is provided at the center of the extension frame 13. A central column 14 is fixedly installed inside the vertical groove. A slider 15 is sleeved on the surface of the central column 14. Mounting plates 16 are fixedly installed at both ends of the slider 15. Mounting plates 20 are fixedly installed at the inner end of the upper half of the upper template 1 and the lower template 3, corresponding to the position of the extension frame 13. The extension frame 13 is fixed on the upper surface of the middle template 2. The central column 14 is fixedly installed inside the extension frame 13. The slider 15 is slidably installed on the surface of the central column 14. When the slider 15 moves, it synchronously drives the mounting plates 16 to move.

[0028] Working principle: The stacked mold drive opening mechanism mainly consists of an upper mold plate 1, a middle mold plate 2, and a lower mold plate 3. It is driven by a pushing mechanism. The fixed block 10 and the positioning rod 11 ensure that the upper and lower mold plates move accurately along a straight line. The limiting block 12 limits the movement distance of the upper mold plate 1 and the lower mold plate 3. The double-headed hydraulic cylinder 6 is fixed on the mounting column 5 at the bottom of the middle mold plate 2. The threaded groove at the outer end of the piston rod 7 is threadedly connected to the limiting plate 9 in the fixed frame 8. The limiting plate 9 is fixed to the surface of the piston rod 7 through a threaded connection, thereby connecting the fixed frame 8 and the piston rod 7. When the double-headed hydraulic cylinder 6 is activated, it pushes the piston rod 7 to both ends. The piston rod 7 pushes the upper mold plate 1 and the lower mold plate 3 on both sides to open the mold. When the plates separate, the slider 15 at the top slides downward along the central column 14, while the extension frame 13 is fixed to the middle template 2. The slider 15 drives the main shaft to move through the mounting plate 16. The main shaft drives the rotating shell 17 to move downward. One end of the connecting rod 18 moves downward, and the other end of the connecting rod 18 expands outward synchronously with the separation of the upper and lower templates. The extension length of the upper and lower molds can be determined by observing the position of the slider 15 on the surface of the central column 14, and the thrust of the double-headed hydraulic cylinder 6 can be adjusted accordingly.
