However, existing precast concrete hoisting and demolding devices have obvious defects in actual use. When using the mold body to produce precast concrete, workers often face the problem of difficulty in quickly removing the precast concrete from the mold body.

[0029] Reference Figures 1-7As shown, this utility model provides a technical solution: a concrete precast component hoisting and demolding device, including a mold body 1, a base plate 2 slidably connected to the surface of the mold body 1, a U-shaped frame 3 fixedly connected to the surface of the mold body 1, two sliding rods 4 slidably inserted inside the U-shaped frame 3, an operating block 5 fixedly connected to one end of the two sliding rods 4, a square plate 6 fixedly connected to the end of the two sliding rods 4 away from the operating block 5, a feed inlet on the surface of the square plate 6, the surface of the square plate 6 slidably connected to the mold body 1, four fixing rods 7 fixedly connected to the surface of the mold body 1, an L-shaped plate 8 slidably connected to the arc surface of the fixing rods 7, an insert rod 9 fixedly connected to the surface of the L-shaped plate 8, the arc surface of the insert rod 9 slidably connected to the mold body 1, and a feed inlet on the surface of the base plate 2. Four slots facilitate the demolding of precast concrete components, preventing difficulties in quickly removing them from the mold body 1 and improving demolding efficiency. A blocking block 10 is fixedly connected to one end of the fixing rod 7. Four square blocks 11 are fixedly connected to the surface of the mold body 1, with a limiting rod 12 slidably inserted within each block 11. A limiting block 13 is fixedly connected to one end of each limiting rod 12, and the limiting block 13 slidably connects to the surface of the mold body 1. When the worker needs to use the mold body 1 to produce precast concrete components, concrete is poured into the feed inlet of the square plate 6. Once the concrete has solidified... Then, the precast concrete component can be ejected from the mold body 1. The L-shaped plate 8 is moved, causing the insert rod 9 to move. When the surface of the L-shaped plate 8 contacts the blocking block 10, the insert rod 9 completely disengages from the surface of the slot in the base plate 2. The limiting rod 12 is moved, causing the limiting block 13 to move. When the limiting block 13 moves between the L-shaped plate 8 and the mold body 1, it can fix the L-shaped plate 8. The operating block 5 is moved, causing the sliding rod 4 to move within the U-shaped frame 3. The sliding rod 4 causes the square plate 6 to move, sliding on the surface of the mold body 1. At this time, the distance between the operating block 5 and the U-shaped frame 3 is close. When the mold body 1 completely disengages from the surface of the precast concrete component, the precast concrete component is demolded, and workers can then remove the precast concrete component. The component is removed from the surface of the base plate 2. The limiting block 13 effectively restricts the movement of the insert rod 9, preventing it from sliding and colliding with the base plate 2, thus avoiding damage. A spring 14 is fitted onto the arc surface of the fixing rod 7. Both ends of the spring 14 are fixedly connected to the mold body 1 and the L-shaped plate 8, respectively. When the worker pulls the L-shaped plate 8, the spring 14 is stretched, causing the L-shaped plate 8 to move the insert rod 9. When the surface of the L-shaped plate 8 contacts the blocking block 10, the insert rod 9 completely disengages from the surface of the slot in the base plate 2. At this point, the worker can use the limiting block 13 to fix the L-shaped plate 8, allowing for demolding of the precast concrete component. After demolding, the mold body 1 is moved back to its original position, and the limiting rod 12 is moved to move the limiting block 13.When the limiting block 13 no longer obstructs the movement of the L-shaped plate 8, the rebound force of the spring 14 drives the L-shaped plate 8 to move, and the L-shaped plate 8 drives the insertion rod 9 to move until the insertion rod 9 is inserted into the surface of the slot of the base plate 2. The rebound force of the spring 14 achieves the effect of automatically inserting the insertion rod 9, while limiting the movement of the insertion rod 9, thus improving the stability of the insertion rod 9 when it is fixed to the base plate 2. Two fixing blocks 21 are fixedly connected to the surface of the U-shaped frame 3. An operating rod 22 is slidably inserted into the fixing block 21. The arc surface of the sliding rod 4 has a groove. When the operator needs to push the operating block 5, the operating rod 22 is moved. When the operating rod 22 is completely disengaged from the surface of the groove of the sliding rod 4, the operating rod 22 releases its fixation on the sliding rod 4. The operator can move the operating block 5, which achieves the effect of fixing the sliding rod 4, indirectly restricting the sliding of the square plate 6, thus facilitating the operator's use. Two rotating blocks 15 are fixedly connected to the surface of the square plate 6. A rotating rod 16 is rotatably connected to the side of the two rotating blocks 15 that is close to each other. A protective plate 17 is fixedly connected to the arc surface of the rotating rod 16. When the operator is not using the mold body 1, the protective plate 17 can be used to protect the feed port of the square plate 6. Rotating the protective plate 17 will cause the rotating rod 16 to rotate. When the protective plate 17 rotates to the surface of the feed port of the square plate 6, the protective plate 17 can protect the feed port of the square plate 6, thus achieving the effect of protecting the square plate 6 from the feed. The material inlet is protected to prevent impurities such as leaves and twigs from entering the mold body 1 through the feed inlet of the square plate 6. An L-shaped block 18 is fixedly connected to the surface of the rotating block 15, and a round rod 19 is slidably inserted into the L-shaped block 18. Two round grooves are opened on the surface of the protective plate 17. When the operator needs to use the mold body 1, the protective plate 17 can be opened and rotated. The protective plate 17 drives the rotating rod 16 to rotate. When the protective plate 17 is fully opened, the round rod 19 is pushed. When the round rod 19 is inserted into the surface of the round groove of the protective plate 17, the round rod 19 can fix the protective plate 17. At this time, the operator can use the mold body 1 normally, achieving the effect of fixing the protective plate 17. To prevent the protective plate 17 from rotating, two torsion springs 20 are fitted onto the arc surface of the rotating rod 16. The two ends of the torsion springs 20 are fixedly connected to the rotating block 15 and the protective plate 17, respectively. When the operator needs to use the protective plate 17 to protect the feed inlet of the square plate 6, they move the round rod 19. When the round rod 19 is completely disengaged from the surface of the circular groove of the protective plate 17, the round rod 19 releases its fixation to the protective plate 17. The torque of the torsion springs 20 drives the protective plate 17 to rotate, which in turn drives the rotating rod 16 to rotate until the protective plate 17 rotates to the surface of the feed inlet of the square plate 6. The torque of the torsion springs 20 achieves the effect of automatically rotating the protective plate 17 to the surface of the feed inlet of the square plate 6, reducing the operator's steps.
[0030] Working principle: When the operator needs to use the mold body 1 to produce precast concrete components, concrete is poured into the feed inlet of the square plate 6. After the concrete solidifies, the precast concrete component can be ejected from the mold body 1. The L-shaped plate 8 is moved, the spring 14 is stretched, and the L-shaped plate 8 drives the insert rod 9 to move. When the surface of the L-shaped plate 8 contacts the blocking block 10, the insert rod 9 completely disengages from the surface of the slot in the base plate 2. The limiting rod 12 is moved, and the limiting rod 12 drives the limiting block 13 to move. When the limiting block 13 moves between the L-shaped plate 8 and the mold body 1, the limiting block 13 can fix the L-shaped plate 8. The operating rod 22 is moved, and when the operating rod 22 completely disengages from the recess of the sliding rod 4... When the surface of the groove is reached, the operating lever 22 releases the fixing of the sliding rod 4, and the operator can move the operating block 5. The operating block 5 drives the sliding rod 4 to move within the U-shaped frame 3, and the sliding rod 4 drives the square plate 6 to move. The square plate 6 slides on the surface of the mold body 1. At this time, the distance between the operating block 5 and the U-shaped frame 3 is close. When the mold body 1 is completely detached from the surface of the precast concrete component, the precast concrete component is demolded. After the operator can remove the precast concrete component from the surface of the base plate 2, the mold body 1 is moved back to its original position, and the operating lever 22 is pushed until the operating lever 22 is inserted into the surface of the groove of the sliding rod 4. At this time, the operating lever 22 can fix the sliding rod 4 and limit its movement. Positioning rod 12 drives limiting block 13 to move. When limiting block 13 no longer obstructs the movement of L-shaped plate 8, the rebound force of spring 14 drives L-shaped plate 8 to move, and L-shaped plate 8 drives insertion rod 9 to move until insertion rod 9 is inserted into the surface of slot in bottom plate 2. At this time, insertion rod 9 can fix bottom plate 2. When the operator needs to use mold body 1, protective plate 17 can be opened and rotated. Protective plate 17 drives rotating rod 16 to rotate. When protective plate 17 is fully opened, push round rod 19. When round rod 19 is inserted into the surface of round groove in protective plate 17, round rod 19 can fix protective plate 17. At this time, the operator can use mold body 1 normally. When personnel need to use the protective plate 17 to protect the feed inlet of the square plate 6, they move the round rod 19. When the round rod 19 is completely detached from the surface of the round groove of the protective plate 17, the round rod 19 releases its fixation to the protective plate 17. The torque of the torsion spring 20 drives the protective plate 17 to rotate, and the protective plate 17 drives the rotating rod 16 to rotate until the protective plate 17 rotates to the surface of the feed inlet of the square plate 6. At this time, the effect of making it convenient for workers to demold the precast concrete components is achieved, avoiding the situation where workers have difficulty quickly removing the precast concrete components from the mold body 1 when using the mold body 1 to produce precast concrete components, resulting in low demolding efficiency.
