Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0020] Example: An automatic positioning and clamping device for casting molds, such as... Figures 1-4As shown, the mold includes a placement platform 1, connecting blocks 2, rotating plates 3, limiting frames 4, mounting frames 5, sliding rods 6, limiting blocks 7, springs 8, guide rods 9, lead screws 10, positioning blocks 11, connecting rods 12, and synchronizing rods 13. The placement platform 1 has positioning grooves 101. Multiple connecting blocks 2 are evenly spaced on the placement platform 1. A rotating plate 3 is rotatably connected between adjacent connecting blocks 2. A limiting frame 4 is installed between two rotating plates 3. The limiting frame 4 has an inverted L-shape inside to facilitate limiting and fixing the casting mold. Mounting frames 5 are symmetrically installed on the left and right sides of the placement platform 1. Sliding rods 6 are symmetrically slidably connected inside both mounting frames 5. Limiting blocks 7 are connected between the inner sides of the two sliding rods 6 to limit the position of the limiting frame 4. Springs 8 are connected between the four sliding rods 6 and the corresponding mounting frames 5. Guide rods 9 are slidably connected to the limiting frame 4. A screw rod 10 is threadedly connected to the limiting frame 4 to adjust the position of the positioning block 11. The front side of the guide rod 9 is connected to the positioning block 11. The front end of the screw rod 10 is rotatably connected to the positioning block 11. The positioning block 11 is inverted L-shaped to facilitate the limiting of the casting mold. Connecting rods 12 are symmetrically connected to the rear end of the screw rod 10 to facilitate the rotation of the screw rod 10. Synchronizing rods 13 are connected to the outer ends of two adjacent sliding rods 6 to enable the two sliding rods 6 to move simultaneously.

[0021] When placing the casting mold, the operator first rotates the connecting rod 12, which drives the lead screw 10 to rotate, causing the lead screw 10 to move forward along the placement platform 1. Simultaneously, it moves the guide rod 9 and the positioning block 11. Once the positioning block 11 is in the correct position, the operator stops rotating the connecting rod 12. Then, the operator pulls the two synchronizing rods 13 outwards, which causes multiple sliding rods 6 and the limiting block 7 to move outwards, compressing the spring 8. Next, the operator rotates the limiting block 7 and the rotating plate 3 upwards along the connecting block 2, causing the limiting frame 4 and all its components to move accordingly. When the limiting frame 4 reaches the correct position, the operator stops rotating the limiting frame 4 and releases the synchronizing rods 13. At this point, the spring 8 pushes the sliding rods 6 and the positioning block 11. 1. Reset: Then, the worker places the casting mold from behind the positioning groove 101 and pushes it to the front end along the positioning groove 101. After the casting mold is placed, the worker pulls the two synchronous rods 13 outward again, causing the limiting block 7 and sliding rod 6 to move outward and compress the spring 8. Then, the rotating limiting frame 4 and rotating plate 3 return to their original positions. During this process, the limiting frame 4 will fix and limit the casting mold, and the positioning block 11 will also play a role in fixing and limiting. When the limiting frame 4 is completely reset, the two synchronous rods 13 are released, and the spring 8 drives the limiting block 7 and sliding rod 6 to reset. Finally, the two limiting blocks 7 limit the limiting frame 4, thus completing the installation, positioning and fixing process of the casting mold, preparing for subsequent processing.
