Description

Technical Field

[0001] This utility model relates to the field of injection mold manufacturing technology, and in particular to a high-precision positioning and alignment mechanism for injection molds. Background Technology

[0002] Injection molds are tools used for injection molding. They typically consist of a moving mold and a fixed mold. Through the injection molding process, thermoplastic or thermosetting plastics are processed into plastic products with specific shapes and sizes. Injection molds are an indispensable tool in the plastics processing industry, enabling the efficient and high-quality production of plastic products. By designing molds of different shapes and structures, a wide variety of plastic products can be produced, widely used in numerous fields such as automotive, electronics, home appliances, medical, and daily necessities.

[0003] During the manufacturing process of injection molds, the moving mold moves up and down under the drive of the pressing mechanism. However, for products with complex shapes, such as automotive interior parts and aerospace components, misalignment of the mold can easily lead to shape distortion and insufficient shape accuracy. Therefore, it is necessary to propose a high-precision positioning and alignment mechanism for injection molds. Utility Model Content

[0018] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0019] like Figures 1 to 3 As shown, this utility model proposes a high-precision positioning and alignment mechanism for injection molds, including a base 1. Two sets of support plates 2 are provided on the top surface of the base 1. The top surface of the base 1 is fixedly connected to the bottom surface of the support plates 2. A threaded rod 3 is rotatably provided between each set of support plates 2. The support plates 2 can support and fix the threaded rod 3, ensuring stable operation. The front end of each threaded rod 3 extends through to the front side of the support plate 2 and is provided with a gear 4. The front end of the threaded rod 3 is fixedly connected to the inner ring of the gear 4. Next, a movable groove is provided on the top surface of the base 1. A motor 5 is provided on the right side of the base 1. The right side of the base 1 is fixedly connected to the left side of the motor 5. A threaded rod 6 is provided at the output end of the motor 5. The output end of the motor 5 is fixedly connected to the right end of the threaded rod 6. The left end of the threaded rod 6 extends through into the interior of the movable groove and is threadedly connected to a threaded block 7. The outer wall of the threaded block 7 is slidably connected to the inner wall of the movable groove, which facilitates the guidance and limitation of the running trajectory of the threaded block 7, so that the threaded block 7 always maintains a straight running state.

[0020] The output of motor 5 drives the second threaded rod 6 to rotate. The rotation of the second threaded rod 6 causes the threaded block 7 to move left and right along the second threaded rod 6. The top surface of the threaded block 7 is equipped with two racks 8, which are fixedly connected to the bottom surfaces of the racks 8. Each rack 8 meshes with a corresponding gear 4. The movement of the threaded block 7 drives both racks 8 to move simultaneously, which in turn drives both gears 4 to rotate simultaneously. Two threaded rods 3 rotate, and each threaded rod 3 has a threaded inclined block 9 threadedly connected to its outer ring. A trapezoidal block 18 is provided on the bottom surface of the threaded inclined block 9. The bottom surface of the threaded inclined block 9 and the top surface of the trapezoidal block 18 are fixedly connected. A trapezoidal groove is provided on the top surface of the base 1 at the position corresponding to each threaded inclined block 9. The trapezoidal block 18 is slidably connected to the trapezoidal groove. The trapezoidal groove can guide and limit the trapezoidal block 18, thereby guiding and limiting the running trajectory of the threaded inclined block 9, so that the threaded inclined block 9 always maintains a straight running state.

[0021] Each threaded inclined block 9 has a triangular block 10 slidably mounted on its top surface. The top surface of the threaded inclined block 9 is inclined, and the bottom surface of the triangular block 10 is inclined, with the two fitting together. A T-slot is formed on the top surface of the threaded inclined block 9, and a T-shaped strip 19 is provided on the bottom surface of the triangular block 10. The bottom surface of the triangular block 10 and the T-shaped strip 19 are fixedly connected, while the T-shaped strip 19 is slidably connected to the T-slot. The movement of the threaded inclined block 9 can drive the T-slot to move, allowing the T-shaped strip 19 to move inside the T-slot. The sliding mechanism causes the triangular blocks 10 to move up and down. Each triangular block 10 has a top seat 11 on its top surface. The top surface of the triangular block 10 is fixedly connected to the bottom surface of the top seat 11. Four guide posts 15 are provided on the left and right sides of the top surface of the base 1. The top surface of the base 1 is fixedly connected to the bottom of the guide posts 15. Each guide post 15 has a guide groove on its top surface. Each top seat 11 has four guide posts 26 on its bottom surface. The bottom surface of the top seat 11 is fixedly connected to the top of the guide posts 26.

[0022] Each guide post 16 has a guide rod 17 on its bottom surface. The bottom surface of the guide post 16 is fixedly connected to the top of the guide rod 17. Each guide rod 17 is slidably connected to a corresponding guide groove, which facilitates guiding and limiting the running trajectory of the top seat 11, ensuring more accurate positioning. A pressure plate 12 is provided between the two top seats 11. The pressure plate 12 is fixedly installed between the two top seats 11. A moving mold base 13 is provided on the bottom surface of the pressure plate 12. The bottom surface of the pressure plate 12 is fixedly connected to the top surface of the moving mold base 13. The top surface of the base 1 is provided with... A fixed mold base 14 is provided, and the top surface of the base 1 is fixedly connected to the bottom surface of the fixed mold base 14. A moving mold base 13 is provided with a moving module 20 on its bottom surface, and the bottom surface of the moving mold base 13 is fixedly connected to the top surface of the moving module 20. A mold groove 21 is provided on the top surface of the fixed mold base 14, and the moving module 20 is slidably connected to the mold groove 21. Four positioning rods 22 are provided on the bottom surface of the moving mold base 13, and the bottom surface of the moving mold base 13 is fixedly connected to the top of the positioning rods 22. Four positioning slots are provided on the top surface of the fixed mold base 14, and the positioning rods 22 are slidably connected to the positioning slots.

[0023] In this embodiment, when using this device, but when it is necessary to move the moving module 20 downwards, the motor 5 is activated. The output of the motor 5 drives the threaded rod 2 6 to rotate. The rotation of the threaded rod 2 6 causes the threaded block 7 to move left and right along the threaded rod 2 6. The movement of the threaded block 7 causes the two racks 8 to move simultaneously. The movement of the two racks 8 causes the two gears 4 to rotate simultaneously. The rotation of the two gears 4 causes the two threaded rods 1 3 to rotate simultaneously. The rotation of the two threaded rods 1 3 causes the two threaded inclined blocks 9 to move along the threaded rods 2 6. The movement of the two threaded inclined blocks 9 can drive the two triangular blocks 10 to move downwards simultaneously, which in turn drives the two top seats 11 to move downwards simultaneously. The downward movement of the two top seats 11 can drive the pressure plate 12 to move downwards. The downward movement of the pressure plate 12 can drive the moving mold seat 13 to move downwards. The downward movement of the moving mold seat 13 can drive the moving module 20 to move downwards. While the top seat 11 moves downwards, it can be assisted in positioning by sliding the guide rod 17 with the guide groove, and it can also be assisted in positioning by sliding the positioning rod 22 with the positioning groove, so as to ensure the machining accuracy.
