Description

Technical Field

[0001] This utility model belongs to the field of cross shaft core technology, and specifically relates to a quick mold change positioning base for cross shaft cores. Background Technology

[0002] The cross shaft core of a coupling refers to the core component of a cross-type universal coupling. Its main function is to connect two rotating shafts and allow them to transmit torque and motion when they are on different axes or have a large angle between them.

[0003] Currently, Chinese utility model patent CN219044092U discloses a positioning structure for quick mold changing. Existing cross shaft cores require mold replacement during processing depending on the model. However, during mold replacement, the upper and lower mold bases need to be accurately positioned together. Since the installation position changes depending on the positions of the upper and lower mold bases, existing positioning bases are inconvenient for adjusting the cross shaft core mold. Furthermore, the installation angle of the cross shaft core mold also changes, making it difficult to accurately position the upper and lower mold bases together, thus hindering mold changing and installation. Utility Model Content

[0004] The purpose of this utility model is to provide a quick mold changing positioning base for cross shaft cores. Its advantage is that it can adjust the position and angle of the cross shaft core mold, thereby accurately positioning the upper and lower mold bases together.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cross-shaped core quick mold changing positioning base, including a base, a rotating platform rotatably connected to the top of the base, a first motor bolted to one side of the base, a first bevel gear rotatably connected to the output end of the first motor, a second bevel gear meshing with the first bevel gear bolted to the bottom of the rotating platform, a sliding platform slidably connected to the top of the rotating platform, and a mold base rotatably connected to the top of the sliding platform.

[0006] By employing the above technical solution, the rotating platform rotates on top of the base, while the sliding platform slides on both sides of the rotating platform's top, allowing the mold inside the mold holder to be freely adjusted to different positions within the rotating range of the platform. This enables precise positioning of the upper and lower mold holders of the cross-shaped core mold, facilitating installation and fixation. Individual rotation and adjustment of the mold holder on top of the sliding platform not only corrects angle changes during the rotating platform's rotation but also allows for free adjustment based on the mold's installation angle, improving practicality.

[0007] The present invention is further configured such that: a second motor is bolted to one end of the rotating table, a threaded rod rotatably connected to the output end of the second motor is bolted to the rotating table, a threaded sleeve bolted to the bottom of the sliding table is threaded onto the surface of the threaded rod, a first spur gear is rotatably connected to one side inside the sliding table, and a second spur gear meshing with the first spur gear is bolted to the bottom of the mold base.

[0008] By adopting the above technical solution, not only can the angle change of the mold seat during the rotation of the rotary table be adjusted back, but it can also be freely adjusted according to the installation angle of the mold.

[0009] The present invention is further configured such that: both sides of the bottom of the rotating platform are rotatably connected to ball bearings that are slidably connected to the base.

[0010] By adopting the above technical solution, the frictional force of the rotating platform rotating on the top of the base is reduced, and the rotational stability is improved.

[0011] The present invention is further configured such that: both sides of the mold base are threadedly connected to threaded shafts, and clamping plates are rotatably connected to the ends of the two threaded shafts that are close to each other.

[0012] By adopting the above technical solution, the rotating threaded shaft engages with the mold seat thread, thereby driving the clamping plates to move closer together to clamp and fix the cross shaft core mold placed on the top of the mold seat, preventing displacement during mold changing.

[0013] The present invention is further configured such that anti-slip pads are adhered to the sides of the two clamping plates that are close to each other.

[0014] By adopting the above technical solution, the friction force when clamping the cross shaft core mold is increased, thereby improving the clamping stability.

[0015] The present invention is further configured such that: heat dissipation mesh is bolted to the base and the rotating platform on the side of the first motor and the second motor respectively.

[0016] By adopting the above technical solution, ventilation and heat dissipation can be provided for the first and second motors, while reducing the amount of dust entering the interior.

[0017] The present invention is further configured such that a limiting bolt that engages with the second circumferential gear is threaded through the side of the sliding table surface away from the first circumferential gear.

[0018] By adopting the above technical solution, the second spherical gear can be locked inside the sliding table by rotating the limiting bolt, thereby limiting and fixing the mold base.

[0019] The present invention is further configured such that the surface of the sliding table is marked with a scale for use with the mold base.

[0020] The above technical solution facilitates observation of the angle scale of the dial indicator, thereby enabling precise control of the adjustment angle of the mold base.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. By rotating the rotating platform on top of the base, while the sliding platform slides on both sides of the rotating platform, the mold inside the mold holder can be freely adjusted to different positions within the rotation range of the rotating platform. This allows for accurate positioning of the upper and lower mold holders of the cross-shaped core mold, facilitating installation and fixation.

[0023] 2. By individually rotating and adjusting the mold base on top of the sliding table, not only can the angle change of the mold base during the rotation of the rotating table be corrected, but it can also be freely adjusted according to the installation angle of the mold, improving practicality.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] Example 1:

[0030] refer to Figure 1 , Figure 2The cross-shaped core quick-change mold positioning base includes a base 1, a rotating platform 2 rotatably connected to the top of the base 1, a first motor 3 bolted to one side of the base 1, a first bevel gear 4 rotatably connected to the base 1 at the output end of the first motor 3, and a second bevel gear 5 meshing with the first bevel gear 4 bolted to the bottom of the rotating platform 2. A sliding platform 9 is slidably connected to the top of the rotating platform 2, and a mold base 10 is rotatably connected to the top of the sliding platform 9. By rotating the rotating platform 2 on the top of the base 1, while the sliding platform 9 slides on both sides of the top of the rotating platform 2, the mold inside the mold base 10 can be freely adjusted to different positions within the rotation range of the rotating platform 2. This allows for accurate positioning of the upper and lower mold bases of the cross-shaped core mold, facilitating installation and fixation.

[0031] refer to Figure 1 , Figure 2 , Figure 3 A second motor 6 is bolted to one end of the rotating platform 2. A threaded rod 7, rotatably connected to the rotating platform 2, is bolted to the output end of the second motor 6. A threaded sleeve 8, bolted to the bottom of the sliding platform 9, is threaded onto the surface of the threaded rod 7. A first spur gear 11 is rotatably connected to one side inside the sliding platform 9. A second spur gear 12, meshing with the first spur gear 11, is bolted to the bottom of the mold base 10. This configuration not only allows adjustment of the angle of the mold base 10 during the rotation of the rotating platform 2, but also enables free adjustment based on the mold's installation angle.

[0032] refer to Figure 2 Both sides of the bottom of the rotating platform 2 are rotatably connected to ball bearings 13 that are slidably connected to the base 1. This reduces the friction of the rotating platform 2 rotating on the top of the base 1 and improves rotational stability.

[0033] refer to Figure 1 Both sides of the mold base 10 are threadedly connected to threaded shafts 17, and clamping plates 18 are rotatably connected to the ends of the two threaded shafts 17 that are close to each other. By rotating the threaded shafts 17 and engaging them with the mold base 10, the clamping plates 18 can be moved closer to each other to clamp and fix the cross shaft core mold placed on the top of the mold base 10, preventing it from shifting position when changing molds.

[0034] refer to Figure 1 , Figure 2 Anti-slip pads 19 are adhered to the sides of the two clamping plates 18 that are close to each other. This increases the friction when clamping the cross shaft mold and improves clamping stability.

[0035] Brief description of the usage process: The mold of the cross shaft core is fixedly installed inside the mold base 10. Then, the first motor 3 is turned on to drive the first bevel gear 4 to mesh with the second bevel gear 5, thereby causing the rotating table 2 to rotate freely on the top of the base 1. Then, the second motor 6 is turned on to drive the threaded rod 7 to engage with the threaded sleeve 8, causing the threaded sleeve 8 to drive the sliding table 9 to slide on the top of the rotating table 2, thereby allowing the mold inside the mold base 10 to be freely adjusted to different positions within the rotation range of the rotating table 2, so that the upper and lower mold bases can be accurately positioned together.

[0036] Example 2:

[0037] refer to Figure 1 , Figure 2 , Figure 3 The quick-change mold positioning base consists of a cross-shaped core. A second motor 6 is bolted to one end of the rotating table 2. A threaded rod 7, rotatably connected to the rotating table 2, is bolted to the output end of the second motor 6. A threaded sleeve 8, bolted to the bottom of the sliding table 9, is threaded onto the surface of the threaded rod 7. A first spur gear 11 is rotatably connected to one side inside the sliding table 9. A second spur gear 12, meshing with the first spur gear 11, is bolted to the bottom of the mold base 10. By individually rotating and adjusting the mold base 10 on top of the sliding table 9, not only can the angle change of the mold base 10 during the rotation of the rotating table 2 be corrected, but it can also be freely adjusted according to the installation angle of the mold, improving practicality.

[0038] refer to Figure 1 , Figure 2 Both the base 1 and the rotating platform 2 are fitted with heat dissipation meshes 15 on the sides closest to the first motor 3 and the second motor 6, respectively. This allows for ventilation and heat dissipation of the first motor 3 and the second motor 6, while also reducing the amount of dust entering the interior.

[0039] refer to Figure 2 A limiting bolt 14, which engages with the second sprocket 12, is threaded through the side of the sliding table 9 away from the first sprocket 11. By rotating the limiting bolt 14, the second sprocket 12 can be locked inside the sliding table 9, thereby limiting and fixing the mold base 10.

[0040] refer to Figure 1 The surface of the sliding table 9 is marked with a scale 16 that works in conjunction with the mold base 10. This allows for easy observation of the angle scale on the scale 16, enabling precise control of the adjustment angle of the mold base 10.

[0041] Brief description of the usage process: By rotating the limiting bolt 14, it engages with the threaded sliding table 9, thereby disengaging from the second sprocket 12. Then, rotating the first sprocket 11 engages with the second sprocket 12, causing the mold base 10 to rotate freely on the top of the sliding table 9. Since the rotation of the rotating table 2 causes the mold angle inside the mold base 10 to change during rotation, the mold base 10 can be adjusted back by rotating it individually, and then the limiting bolt 14 can be rotated in the opposite direction to lock the limiting position.

[0042] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
