[0001] The utility model relates to the field of casting moulds, in particular to a casting mould quick-changing device. Background Art

[0002] When casting molds are used continuously for a long time, they may suffer from problems such as wear, cracks, corrosion, and thermal deformation. When the casting molds have the above defects, they need to be replaced to ensure the quality of the castings and production efficiency. However, the existing casting method is to arrange the casting molds in a row, and then the workers move them back and forth to cast. This method is not only labor-intensive, but also prone to problems such as slow casting speed due to fatigue, low casting efficiency and quality, which can easily affect the production process and increase the number of defective products. Therefore, how to overcome the above-mentioned technical problems and defects has become a key issue that needs to be solved. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0025] See also Figure 1-Figure 4 The casting mold rapid replacement device of this embodiment can assemble multiple molds at the same time and limit the molds, thereby realizing cyclic casting. At the same time, it can fix the rotating assembly table, stop it from rotating, and stay in a predetermined position, so as to realize the rapid casting and removal of parts, thereby achieving an uninterrupted casting effect and reducing the labor intensity of the staff. In this embodiment, it mainly includes an equipment base 1, and a liftable operating table 2 is provided on the upper part of the equipment base 1. A lifting cylinder 6 is fixedly provided on the top of the equipment base 1, and the lifting cylinder 6 is inserted into the interior of the operating table 2 from the bottom end of the operating table 2 and is slidably arranged therewith. A power chamber 7 is provided inside the lifting cylinder 6.

[0026] Inside the equipment base 1 is a power module 3 that drives the operating platform 2 up and down. This power module 3 includes a screw 31 fixed vertically in the middle of the bottom end of the operating platform 2. The bottom of the screw 31 extends through the top of the lifting cylinder 6 and into the power chamber 7. A transmission sleeve 32, rotatably mounted on the top of the power chamber 7, is threadedly connected to and enclosed by the screw 31. A first gear 33 is fixedly mounted on the bottom end of the transmission sleeve 32. A bidirectional motor 34 is fixedly mounted inside the power chamber 7. A second gear 35 fixed to its output end engages with the first gear 33. Controlling the bidirectional motor 34 drives the first gear 33 through the second gear 35, which in turn rotates the transmission sleeve 32, thereby driving the screw 31 up and down, and thus the operating platform 2. This facilitates pouring operations for workers of different heights and accommodates different liquid pouring heights. A guide block 36 is fixedly mounted on the top of the lifting cylinder 6, and a guide rail 37 is fixedly mounted inside the operating platform 2 to guide the guide block 36. Provide guidance and limit for the lifting of the operating table 2 to ensure its vertical lifting and avoid the position of the mold changing during lifting.

[0027] In order to achieve the installation of the mold. Figure 1-Figure 3In this embodiment, an assembly table 4 for placing molds is rotatably provided at the top of the operating table 2. A drive chamber 8 is provided at the top of the operating table 2. The assembly table 4 is annularly structured and sleeved on the top of the operating table 2, and its inner ring is inserted into the interior of the drive chamber 8. The assembly table 4 rotates on the operating table 2. A plurality of mold mounting tables 9 are fixedly provided on the outer ring of the assembly table 4, and at least two locating pins 10 are vertically fixed on the top of the mold mounting table 9. The lengths of the two locating pins 10 are inconsistent to facilitate the subsequent opening and closing of the mold. Multiple molds can be assembled for cyclic casting, and the locating pins 10 are used for positioning to achieve rapid casting and removal of parts.

[0028] In order to realize the cyclic rotation and fixation of the assembly platform. In this embodiment, see Figure 2 and Figure 4 The operating table 2 is internally provided with a drive module 5 that drives the assembly table 4 to rotate. The drive module 5 includes an annular gear ring 51 fixedly mounted on the inner ring of the operating table 2 within the drive chamber 8. A drive motor 52 is fixedly mounted within the drive chamber 8. The drive motor 52 is fixedly mounted to the operating table 2, and a third gear 53 is fixedly mounted on the output end of the drive motor 52, which meshes with the annular gear ring 51. The drive motor 52 is controlled to rotate, and the third gear 53 drives the annular gear ring 51 to rotate, thereby driving the operating table 2 to rotate, achieving cyclic rotation of the assembly table 4. A plurality of limiting slots 54 are defined on the inner ring of the operating table 2 below the annular gear ring 51, corresponding to the positions of the mold mounting table 9. An electric push rod 55 is fixedly mounted horizontally on the operating table 2 within the drive chamber 8. The telescopic portion of the electric push rod 55 is fixedly mounted with a limiting rod 56 that can be inserted into the limiting slot 54. A spring 57 is fixedly mounted between the tail end of the limiting rod 56 and the operating table 2, and is sleeved on the electric push rod 55. When the corresponding mold needs to be moved, the electric push rod 55 is controlled to retract, moving the limiting rod 56 out of the corresponding limiting groove 54. When the assembly platform 4 rotates, the control of the electric push rod 55 is disconnected, and the limiting rod 56 abuts the assembly platform 4 under the action of the spring 57. When the mold rotates to the casting position, the limiting rod 56 is inserted into the corresponding limiting groove 54 under the action of the spring 57. This fixes the rotating assembly platform 4, causing it to stop rotating and remain in the predetermined position, facilitating subsequent casting operations.

[0029] The method for using the casting mold quick-change device of the present invention is as follows: First, the bidirectional motor 34 is controlled to rotate, driving the first gear 33 via the second gear 35. This rotates the transmission sleeve 32, thereby driving the screw 31 to rise and fall, thereby achieving the lifting and lowering of the operating platform 2. This facilitates the pouring operation for workers of different heights and can adapt to different liquid pouring heights. During this process, the guide block 36 and guide rail 37 provide guidance and limit for the lifting and lowering of the operating platform 2, ensuring its vertical lifting and preventing the position of the molds from changing during lifting. The multiple molds are then secured to the mold mounting platform 9 via locating pins 10. The drive motor 52 is then controlled to rotate, driving the annular gear 51 via the third gear 53, thereby driving the operating platform 2 to rotate, achieving cyclic rotation of the assembly platform 4. During this process, the electric push rod 55 is controlled to retract, moving the limit rod 56 out of the corresponding limit slot 54. When the assembly platform 4 rotates, the control of the electric push rod 55 is disconnected, and the limit rod 56 abuts the assembly platform 4 under the action of the spring 57. When the mold rotates to the casting position, the limiting rod 56 is inserted into the corresponding limiting groove 54 under the action of the spring 57. Thereby the rotating assembly platform 4 is fixed, stopped, and stays in a predetermined position, which is convenient for subsequent casting operations.
