[0020] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0022] See also Figures 1-4 This embodiment provides a precision casting device for castings, including a fixed plate 1, on which a fixing device 2 is provided. The fixing device 2 includes a fixing block 21, which is fixedly connected to the front of the fixed plate 1. A slide bar 22 is fixedly connected to the bottom of the fixed block 21. A clamping block 23 is slidably connected to the outer wall of the slide bar 22. A collar 25 is fixedly connected to the front of the clamping block 23. A first rack 26 is fixedly connected to the inner wall of the collar 25. A first rotating rod 27 is rotatably connected to the front of the fixed plate 1 through a bearing. A first circular gear 28 is fixedly connected to the front of the first rotating rod 27. The connection between the fixed plate 21 in the mounting device 2 and the right side of the lower mold 4 is manufactured using a precision machining process to improve stability. The pulley 28 can be made of a highly wear-resistant material to ensure reliability and smooth sliding during long-term use. The clamping block 23 is fixedly connected to the clamping box 24 at the bottom, and the fixed plate 1 is provided with a slide 29. The back of the fixed plate 1 is fixedly connected to the first hydraulic cylinder 210. The bottom of the output end of the first hydraulic cylinder 210 is fixedly connected to a connecting rod 211. The connecting rod 211 is slidably connected to the inner wall of the slide 29. The baffle 210 at the bottom of the slide 24 is designed with a protective edge to prevent the spring 29 from falling off during use. The material of the spring 29 is selected from high-elastic alloy steel to ensure that the elasticity is not reduced during long-term use. The first rack 26 is meshed with the first circular gear 28. The bottom of the fixed plate 1 is fixedly connected to the base 4. The connection between the spring 29 at the bottom of the baffle 210 and the bottom of the fixed plate 21 adopts a reinforced welding process to improve the connection strength and durability. This design ensures that the spring 29 will not shift when subjected to force, thereby maintaining stable casting accuracy.

[0023] When the above-mentioned equipment is in use, the casting mold is placed inside the clamping box 24.
