[0029] The technical solutions of the present invention will be described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments. Specific Implementation Example 1

[0031] Please see Figures 1-5 This utility model is a 3D printed sand mold for casting seat mold core, including a 3D upper sand mold 1 and a 3D lower sand mold 101 disposed above the 3D upper sand mold 1;

[0032] Fixing mechanism 2 is located on both sides of the 3D sand mold 1. Fixing mechanism 2 includes fixing blocks 1 201 fixedly installed on both sides of the 3D sand mold 1. Fixing blocks 202 are positioned above the fixing blocks 1 201, and buckles 204 are positioned below the fixing blocks 202. Fixing plates 203 are fixedly installed on the bottom surfaces of the two fixing blocks 1 201, and two buckles 204 are fixedly installed on the bottom surfaces of the two fixing plates 203. Slots 205 are formed on the top surfaces of the two fixing blocks 202, and the buckles 204 engage with the slots 205. Two movable slots 206 are formed inside the two fixing blocks 202, and movable plates 207 are slidably installed on the inner walls of the movable slots 206. 7. Each side is fixedly installed with abutment blocks 208. One end of each abutment block 208 slides through the inner wall of each moving groove 206 and extends into the two slots 205. One end of each abutment block 208 contacts the side of each buckle 204. Each side of each moving plate 207 is fixedly installed with springs 209. One end of each spring 209 is fixedly connected to the inner wall of each moving groove 206. Each inner wall of each moving groove 206 has an adjustment groove 210. Each side of each moving plate 207 is fixedly installed with an adjustment rod 211. The sides of each adjustment rod 211 slide to the inner wall of each adjustment groove 210. The top surfaces of the two fixed blocks 1 201 are fixedly connected to the two fixed blocks 202 by two bolts 212.

[0033] Specifically: By placing the 3D upper sand mold 1 on top of the 3D lower sand mold 101, the 3D upper sand mold 1 moves the fixing block 201, causing the fixing plate 203 and the buckle 204 to move downwards. The buckle 204 moves into the slot 205 and abuts against the slot 205, thereby limiting and fixing the 3D upper sand mold 1 and the 3D lower sand mold 101. This makes it less likely for the 3D upper sand mold 1 to shift when it is placed on top of the 3D lower sand mold 101, and allows for quick installation, improving the efficiency of subsequent pouring. Pushing the set adjustment rod 211 moves the moving plate 207 and the abutment block 208. The abutment block 208 pushes the buckle 204 to move, and the buckle 204 disengages from the slot 205, thus facilitating the separation of the 3D upper sand mold 1 and the 3D lower sand mold 101. Specific Implementation Example 2

[0035] Please see Figures 1-5Based on the first specific embodiment, a limiting mechanism 3 is located above the 3D lower sand mold 101. The limiting mechanism 3 includes four protrusions 303 integrally installed on the top surface of the 3D lower sand mold 101. The bottom surface of the 3D upper sand mold 1 has four grooves 305. The inner walls of the four grooves 305 are slidably connected to the outer walls of the four protrusions 303. Limiting holes 306 are respectively opened on the inner walls of the four grooves 305. Limiting posts 304 are fixedly installed on the top surface of the four protrusions 303. The outer walls of the four limiting posts 304 are slidably connected to the inner walls of the four grooves 305. Two limiting blocks 301 are fixedly installed on the bottom surface of the 3D upper sand mold 1. Two limiting grooves 302 are opened on the top surface of the 3D lower sand mold 101. The outer walls of the two limiting blocks 301 are slidably connected to the inner walls of the two limiting grooves 302.

[0036] Specifically: The limiting block 301 and the limiting groove 302 are set to limit the 3D upper sand mold 1 and the 3D lower sand mold 101. The protrusion 303, the limiting post 304, the groove 305 and the limiting hole 306 are set to further limit the 3D upper sand mold 1 and the 3D lower sand mold 101, so that the 3D upper sand mold 1 and the 3D lower sand mold 101 are not easily misaligned, thus improving the quality of casting.

[0037] The working principle of this utility model is as follows: A 3D upper sand mold 1 is placed on top of a 3D lower sand mold 101. The upper and lower sand molds 1 and 101 are positioned using a limiting block 301 and a limiting groove 302. The protrusion 303, limiting post 304, groove 305, and limiting hole 306 further limit the positions of the upper and lower sand molds 1 and 101, preventing them from shifting and improving the quality of the casting. Simultaneously, the upper sand mold 1 moves the fixing block 201, which in turn moves the fixing plate 2. 03 and buckle 204 move downwards, buckle 204 moves into the slot 205 and abuts against the slot 205, thereby limiting and fixing the 3D upper sand mold 1 and the 3D lower sand mold 101, so that the 3D upper sand mold 1 covering the 3D lower sand mold 101 is not prone to displacement, and the installation is quick, improving the efficiency of subsequent pouring. Push the set adjustment rod 211, drive the moving plate 207 and the abutment block 208 to move, the abutment block 208 pushes the buckle 204 to move, the buckle 204 disengages from the slot 205, thereby facilitating the separation of the 3D upper sand mold 1 and the 3D lower sand mold 101.
