[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-3 , the present utility model provides a technical solution: a sand core assembly jig, including a bracket 1. A first guiding slide column 4 is fixedly connected to one side above the bracket 1. A sub-core A placement plate 2 is slidably connected to the surface of the first guiding slide column 4. A sub-core A body 3 is clamped to the upper end of the sub-core A placement plate 2. A sub-core B placement plate 8 is fixedly connected to the other side above the bracket 1. A sub-core B body 9 is clamped inside the sub-core B placement plate 8. A pushing device 17 is fixedly connected to one side of the bracket 1. One end of the pushing device 17 is fixedly connected to a sub-core C body 10.

[0017] In this embodiment, the body 9 of the sub-core B is placed inside the placement plate 8 of the sub-core B for positioning. At this time, the body 10 of the sub-core C is positioned and placed inside the placement plate 18 of the sub-core C. The placement plate 18 of the sub-core C is pushed by the provided pushing device 17 to be clamped on the side of the body 9 of the sub-core B, so as to lock and dock the body 9 of the sub-core B and the body 10 of the sub-core C. Similarly, at the other end of the body 9 of the sub-core B, the placement plate 2 of the sub-core A is slid so that the body 3 of the sub-core A can be docked at one end of the body 9 of the sub-core B, thus completing the composition. This design method uses tooling for assembly, enabling the three cores to quickly complete docking and splicing, with high assembly efficiency and improved production efficiency.

[0018] Specifically, the pushing device 17 includes a second guiding slide post 5, a fixing plate 6, and a telescopic cylinder 7. The telescopic cylinder 7 is fixedly connected to the side of the bracket 1. The second guiding slide post 5 is fixedly connected to the side of the bracket 1. The fixing plate 6 is slidably sleeved on the surface of the second guiding slide post 5. One end of the telescopic cylinder 7 is fixedly connected to the fixing plate 6.

[0019] In this embodiment, the second guiding slide post 5 provided can limit the sliding of the fixing plate 6 to be more stable, and the telescopic cylinder 7 provided can push the fixing plate 6 to move, thereby pushing the body 10 of the sub-core C to be docked and spliced with the body 9 of the sub-core B.

[0020] Specifically, a locking device 11 is fixedly connected to one end of the first guiding slide post 4. The locking device 11 includes a fixed ear 12, a locking rod 13, a locking spring 15, and a limiting post 16.

[0021] In this embodiment, by providing the locking device 11, the placement plate 2 of the sub-core A can be locked, thus completing the docking.

[0022] Specifically, the fixed ear 12 is rotatably connected to the locking rod 13 through a shaft. A locking spring 15 is fixedly connected to the lower part of one end of the locking rod 13. One end of the locking spring 15 is fixedly connected to the upper end of the bracket 1. Limiting posts 16 are arranged at both ends inside the locking spring 15. A locking groove 14 is fixedly opened at one end of the locking rod 13.

[0023] In this embodiment, during the sliding process of the placement plate 2 of the sub-core A, the locking rod 13 is at the lower end of the placement plate 2 of the sub-core A. At this time, the locking spring 15 is compressed by force. When the body 3 of the sub-core A completes docking, one end of the placement plate 2 of the sub-core A can be clamped inside the locking groove 14. At this time, under the elastic action of the locking spring 15, the locking rod 13 can abut against and lock the placement plate 2 of the sub-core A, so that the body 3 of the sub-core A can complete docking with the body 9 of the sub-core B.

[0024] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
