Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a core mold vibration tube making machine pressing mechanism. Background Technology

[0002] The core mold vibration pipe making machine is a special equipment used to produce concrete pipes such as drainage pipes and culverts. Its core feature is that it uses a vibrating core mold to compact the concrete. During production, a pressing mechanism is needed to position and lock the core mold.

[0003] Existing core mold vibration tube making machine pressing mechanisms, such as the Chinese utility model patent CN214491032U entitled "A Core Mold Vibration Tube Making Machine Pressing Mechanism," include a gantry, a pressing cylinder, an upper template, and an upper mold core. The pressing cylinder is installed on one side of the top of the gantry, and guide components are installed through the interior of the gantry on both sides of the pressing cylinder. The upper template is installed at the bottom of the push mold frame, and the upper mold core is fixed at the center of the bottom of the upper template. Pinning components are installed at equal angles on the bottom of the upper template outside the upper mold core. In this patented solution, the gantry is narrow and long, with low strength, making it prone to deformation under stress during pressing, leading to displacement of other structures. Furthermore, the pressing cylinder is located at the center of the push mold frame, resulting in a small and concentrated force application area, making it impossible to stably compress the edge of the upper template through the push mold frame, resulting in poor actual pressing effect. To address these problems, an innovative design based on the existing core mold vibration tube making machine pressing mechanism is urgently needed. Utility Model Content

[0004] The purpose of this utility model is to provide a core mold vibration tube making machine pressing mechanism to solve the problems mentioned in the background art, such as the narrow and long gantry of the existing device, low strength, easy deformation under force during the pressing process, resulting in the displacement of other structures, and the pressing cylinder being set in the center of the push mold frame, with a small and concentrated force application area, which makes it impossible to stably squeeze the edge of the upper template through the push mold frame, resulting in poor actual pressing effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a core mold vibration tube-making machine pressing mechanism, including a lower gantry, a servo motor installed at the bottom of the lower gantry, a central shaft installed at the top of the servo motor, the top of the central shaft being rotatably connected to the bottom surface of the upper gantry, a drive gear fixedly installed at the bottom of the central shaft, the drive gear meshing with a driven gear, the driven gear being fixed to the top of the outer wall of a vertical sleeve, the vertical sleeve being installed through a bearing seat on the lower gantry, a vertical threaded rod being installed through the center of the vertical sleeve, the top of the vertical threaded rod being connected to the inner wall of a stabilizing sleeve, the top of the stabilizing sleeve being fixedly connected to the bottom surface of the upper gantry, a limit block being fixedly fixed at the top of the vertical threaded rod, the limit block being fitted against the inner side of a track groove, the track groove being formed on the inner wall of the stabilizing sleeve, a reinforcing rib plate being fixedly fixed at the bottom of the vertical threaded rod, and both the bottom end of the vertical threaded rod and the bottom end of the reinforcing rib plate being fixedly connected to the top surface of the push mold frame.

[0006] Preferably, the lower gantry and the upper gantry have the same planar dimensions, the lower gantry and the upper gantry are parallel to each other, and the thickness of the upper gantry is not less than half the thickness of the lower gantry.

[0007] Preferably, the driven gears are distributed at equal angles with respect to the center of the driving gear, and the diameter of the driving gear is smaller than the diameter of the driven gear.

[0008] Preferably, the vertical sleeve and the vertical threaded rod are connected by a thread, and the length of the vertical sleeve is greater than 1 / 4 of the overall length of the vertical threaded rod.

[0009] Preferably, the vertical threaded rod and the stabilizing sleeve are slidably connected, the length of the stabilizing sleeve is greater than 1 / 3 of the length of the vertical threaded rod, and limit blocks are symmetrically distributed on both sides of the top of the vertical threaded rod, and the limit blocks are slidably connected to the track groove.

[0010] Preferably, an upper template is installed at the bottom of the push mold frame, an upper mold core is installed at the bottom of the upper template, and a pin fixing component is installed at the bottom edge of the upper template.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the core mold vibration tube making machine pressing mechanism adopts a new structural design, which not only greatly increases the overall strength of the structure and ensures that each component is not easily deformed or displaced during operation, but also disperses the force application position and, together with the guiding and stabilizing mechanism, ensures that the upper template can be fully and evenly extruded.

[0012] 1. The central shaft driven by the servo motor synchronously drives the driven gears that are distributed at equal angles, so that the driven gears stably drive the vertical sleeve to rotate. The distributed vertical thread rods are driven to move steadily vertically along the stable sleeve by the threaded connection relationship. The reinforcing ribs work together to fully and evenly compress the push mold frame and the upper mold plate.

[0013] 2. The structural design of the lower gantry, upper gantry, vertical threaded rod, and stabilizing sleeve significantly increases the overall structural strength of the device, ensuring that the installation foundation composed of the lower and upper gantry is not easily deformed during the downward extrusion process of the vertical threaded rod, thus enabling each component to work stably.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0020] Please see Figure 1-4This utility model provides a technical solution: a core mold vibration tube making machine pressing mechanism, including a lower gantry 1, a servo motor 2, a central shaft 3, an upper gantry 4, a driving gear 5, a driven gear 6, a vertical sleeve 7, a vertical threaded rod 8, a stabilizing sleeve 9, a limiting block 10, a track groove 11, a reinforcing rib plate 12, a push mold frame 13, an upper template 14, a pin fixing assembly 15, and an upper mold core 16. The servo motor 2 is installed at the bottom of the lower gantry 1, and the central shaft 3 is installed at the top of the servo motor 2. The top of the central shaft 3 is rotatably connected to the bottom surface of the upper gantry 4. The driving gear 5 is fixedly installed at the bottom of the central shaft 3, and the driving gear 5 and the driven gear 6 are connected. The driven gear 6 is fixed to the top of the outer wall of the vertical sleeve 7. The vertical sleeve 7 is installed on the lower gantry 1 through a bearing seat. A vertical threaded rod 8 is installed through the center of the vertical sleeve 7. The top of the vertical threaded rod 8 is connected to the inner wall of the stabilizing sleeve 9. The top of the stabilizing sleeve 9 is connected and fixed to the bottom surface of the upper gantry 4. A limit block 10 is fixed to the top of the vertical threaded rod 8. The limit block 10 fits against the inner side of the track groove 11. The track groove 11 is opened on the inner wall of the stabilizing sleeve 9. A reinforcing rib plate 12 is fixed to the bottom of the vertical threaded rod 8. The bottom end of the vertical threaded rod 8 and the bottom end of the reinforcing rib plate 12 are both connected and fixed to the top surface of the push mold frame 13.

[0021] In this example, the lower gantry 1 and the upper gantry 4 have the same planar dimensions and are distributed in parallel. The thickness of the upper gantry 4 is not less than half the thickness of the lower gantry 1. The above structural design strengthens the overall installation foundation and ensures that the lower gantry 1 and the upper gantry 4 will not deform during the molding process.

[0022] Driven gears 6 are distributed at equal angles to the center of driving gear 5. The diameter of driving gear 5 is smaller than the diameter of driven gears 6. The above structural design enables driving gear 5 to stably and synchronously drive multiple driven gears 6 and vertical sleeve 7 to rotate.

[0023] The vertical sleeve 7 and the vertical threaded rod 8 are connected by threads. The length of the vertical sleeve 7 is greater than 1 / 4 of the overall length of the vertical threaded rod 8. The above structural design ensures that the contact length between the vertical sleeve 7 and the vertical threaded rod 8 is sufficient, which improves the stability of the vertical threaded rod 8 and drives the vertical threaded rod 8 to move vertically in a stable manner by utilizing the threaded connection.

[0024] The vertical threaded rod 8 and the stabilizing sleeve 9 are slidably connected. The length of the stabilizing sleeve 9 is greater than 1 / 3 of the length of the vertical threaded rod 8. Limiting blocks 10 are symmetrically distributed on both sides of the top of the vertical threaded rod 8. The limiting blocks 10 are slidably connected to the track groove 11. The above structural design limits the vertical threaded rod 8 to ensure that the vertical threaded rod 8 can move stably and vertically along the track groove 11 with the limiting blocks 10.

[0025] The upper template 14 is installed at the bottom of the push mold frame 13, the upper mold core 16 is installed at the bottom of the upper template 14, and the pin assembly 15 is installed on the bottom edge of the upper template 14. The above structural design enables the push mold frame 13 to move stably with the upper template 14 and the upper mold core 16 when the vertical threaded rod 8 extrudes and pushes the push mold frame 13.

[0026] Working principle: During installation, the lower gantry 1 and the upper gantry 4 are normally connected to the core mold vibration tube making machine. During use, the servo motor 2 is started and controlled to drive the central shaft 3 to rotate steadily in the positive direction with the active gear 5. The active gear 5 synchronously drives the driven gears 6, which are distributed at equal angles, to rotate slowly and steadily in the same direction with the vertical sleeve 7. The vertical sleeve 7 drives the vertical threaded rod 8 to slide vertically down along the stabilizing sleeve 9 using the threaded connection relationship. The limiting block 10 at the top of the vertical threaded rod 8 slides linearly along the track groove 11.

[0027] The vertical threaded rods 8, which are distributed at equal angles and have large spacing, work together with the reinforcing ribs 12 at the bottom to perform multi-point, large-area vertical compression on the push mold frame 13, pushing the upper template 14 and the upper mold core 16 to move vertically and stably, ensuring the stability of the mold. This is the working principle of the mold pressing mechanism of the core mold vibration tube making machine.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
