[0002] In the production process of concrete precast components, processes such as mold making and on-site casting are required at the construction site. After molding, demolding is needed. To facilitate the separation of the reinforced concrete precast member from the mold, a turnover device is used to drive the mold to rotate, so that the reinforced concrete precast member is separated from the mold. When the turnover demolding device separates the reinforced concrete precast member from the mold, the dropped reinforced concrete precast member collides with the supporting surface, and the collision intensity between the reinforced concrete precast member and the supporting surface is relatively large, which easily causes the reinforced concrete precast member to break. At the same time, the dropped reinforced concrete precast member is located below the mold, and it is inconvenient to transfer the reinforced concrete precast member due to the blockage of the mold. Content of the Utility Model

[0014] The beneficial effects of the present utility model are as follows:

[0015] In the initial state when loading the mold, the placement plate is located below the feeding port and is in a horizontal state. One side of the mold is placed on the placement plate from the feeding port. At this time, the prefabricated part formed in the mold is facing upward and is located below the clamping block. At the same time, the elastic material receiving seat is located behind the placement plate. The clamping mechanism is started to clamp the mold on the placement plate. Then, the rotary drive motor is started to drive the corresponding connected driving gear to rotate clockwise for a set number of turns. With the cooperation of the first driven gear, the driving gear drives the toothed ring to rotate counterclockwise. The toothed ring thus drives the circular frame to rotate counterclockwise, and the mold between the clamping block and the placement plate is flipped so that the prefabricated part in the mold faces downward. During this process, the driving gear connected to the rotary drive motor simultaneously drives the transmission gear to rotate counterclockwise. The transmission gear drives the sprocket drive assembly to drive, and the sprocket drive assembly drives the elastic material receiving seat to move forward. When the prefabricated part in the mold faces downward, the elastic material receiving seat is located directly below the prefabricated part. Then, the rotary drive motor stops working, and the vibration mechanism is started to drive the entire placement plate to vibrate. At this time, the mold clamped on the placement plate vibrates up and down between the clamping mechanism and the placement plate and repeatedly impacts the placement plate, so that the prefabricated part in the mold falls off and lands on the elastic material receiving seat. The elastic material receiving seat reduces the collision intensity between the prefabricated part and the material receiving plate, making the prefabricated part not easily break.

[0016] After demolding is completed, the rotation drive motor is started again to drive the connected driving gear to rotate counterclockwise by a set number of turns for resetting. The driving gear drives the toothed ring to rotate clockwise by a set number of turns, causing the mold to flip and reset again, so that the opening of the mold for dropping the prefabricated part faces upward. At the same time, the driving gear drives the transmission gear to rotate clockwise by a set number of turns for resetting, driving the sprocket transmission assembly to reset, thereby driving the elastic material receiving seat to move backward for resetting, making the placement plate and the elastic material receiving seat be misaligned, so that there is no obstruction above the elastic material receiving seat, facilitating the transfer of the demolded prefabricated part and improving work efficiency.

[0031] As a preferred solution, as Figure 3 shown, the turning driving assembly 12 further includes a support frame 127 and a second driven gear 128, the support frame 127 is vertically and fixedly arranged on the upper surface of the base 121, the top of the support frame 127 extends above the circular frame 125, the second driven gear 128 is rotatably connected to the top of the support frame 127, and the lower end of the second driven gear 128 meshes with the upper end of the toothed ring 124. Through the combined use of the support frame 127 and the second driven gear 128, the lower end of the second driven gear 128 meshes with the upper end of the toothed ring 124, so that when the toothed ring 124 rotates, it drives the circular frame 125 to rotate, thereby making the rotation process of the circular frame 125 more stable.

[0032] As a preferred solution, as Figure 1As shown, the vibration mechanism includes a vibration motor and a vibration assembly. The vibration motor is arranged at the bottom of the placement plate 3. There are two groups of vibration assemblies, which are respectively arranged on the inner side walls of two circular frames 125 and are both located at the bottom of the placement plate 3. The vibration assembly includes a support block 22, a support rod 23, a first spring 24 and a limit block 25. The support block 22 is fixedly arranged on the inner side wall of the circular frame 125. The upper end of the support rod 23 is fixedly connected to the bottom of the placement plate 3. The lower end of the support rod 23 passes through the support block 22 and is connected to the limit block 25. The support rod 23 is slidably sleeved on the support block 22. The first spring 24 is sleeved on the support rod 23. The upper and lower ends of the first spring 24 are respectively connected to the bottom of the placement plate 3 and the top of the support block 22. By driving the placement plate 3 as a whole to vibrate through the vibration motor, the placement plate 3 vibrates up and down on the support block 22 under the action of the first spring 24 and the support rod 23. At this time, the mold 6 clamped on the placement plate 3 vibrates up and down between the clamping mechanism 4 and the placement plate 3 and repeatedly impacts the placement plate 3, so that the prefabricated parts 7 in the mold 6 fall off.

Then the electric push rod 42 is started to drive the clamping block 43 to move downward, and the mold 6 is clamped by the clamping block 43 with an inverted "concave" structure. When the circular frame 125 rotates, it drives the clamping block 43 and the placement plate 3 to rotate in the front and rear directions, which can prevent the mold 6 from falling off.

[0034] As a preferred solution, as Figure 1As shown in the figure, the sprocket drive assembly 51 includes a first rotating shaft 511, a second rotating shaft 512 and a sprocket assembly.

The driving sprocket 513 is fixedly sleeved on the first rotating shaft 511, the driven sprocket 514 is fixedly sleeved on the second rotating shaft 512, and the chain 515 is sleeved on the driving sprocket 513 and the driven sprocket 514 in a transmission manner. The elastic material receiving seat 53 is fixedly installed on the upper surfaces of the two chains 515. By starting the motor to drive the driving gear 122 to rotate, the transmission gear 52 is driven to rotate. The transmission gear 52 drives the first rotating shaft 511 to rotate. The first rotating shaft 511 drives the driving sprocket 513 to rotate, and then drives the chain 515 and the driven sprocket 514 to rotate. The chain 515 drives the elastic material receiving seat 53 to move along the front-back direction of the base 121, which is convenient for material receiving and discharging.

[0035] As a preferred solution, the elastic material receiving seat 53 includes a material receiving plate 531, an elastic pad 532, a sliding rod 533 and a second spring 534.

When the prefabricated part 7 falls on the elastic pad 532 located below the placing plate 3 during demoulding, the collision intensity between the prefabricated part 7 and the material receiving plate 531 is reduced through the elastic pad 532. Further, through the cooperation of the sliding rod 533 and the spring, when the prefabricated part 7 falls on the elastic pad 532, the prefabricated part 7 can be unloaded on the elastic pad 532, so that the prefabricated part 7 is not easily broken.

[0036] The working mode of the present utility model is as follows:

[0037] During use, initially, when loading the mold 6, the placement plate 3 is located below the feed inlet 126 and is in a horizontal state. One side of the mold 6 is placed on the placement plate 3 from the feed inlet 126. At this time, the prefabricated part 7 formed in the mold 6 is facing upward and is located below the clamping block 43. At the same time, the elastic material receiving seat 53 is located at the rear side of the placement plate 3. Start the electric push rod 42 to drive the clamping block 43 to move downward, and clamp the mold 6 through the clamping block 43 with an inverted "concave" structure. Then start the rotary drive motor 11 to drive the corresponding connected driving gear 122 to rotate clockwise (viewed from the right) for a set number of turns. The driving gear 122, under the cooperation of the first driven gear 123, drives the toothed ring 124 to rotate counterclockwise. The toothed ring 124 thus drives the circular frame 125 to rotate counterclockwise, and flips the mold 6 between the clamping block 43 and the placement plate 3, so that the prefabricated part 7 in the mold 6 faces downward. During this process, the driving gear 122 connected to the rotary drive motor 11 simultaneously drives the transmission gear 52 to rotate counterclockwise. The transmission gear 52 drives the first rotating shaft 511 to rotate counterclockwise for a set number of turns, thereby driving the driving sprocket 513 on the first rotating shaft 511 to rotate counterclockwise for a set number of turns, and driving the elastic material receiving seat 53 on the chain 515 to move forward, so that when the prefabricated part 7 in the mold 6 faces downward, the elastic material receiving seat 53 is located directly below the prefabricated part 7. Then the rotary drive motor 11 stops working, and then start the vibration motor to drive the entire placement plate 3 to vibrate, so that the placement plate 3 vibrates up and down on the support block 22 under the action of the first spring 24 and the support rod 23. At this time, the mold 6 clamped on the placement plate 3 vibrates up and down between the clamping mechanism 4 and the placement plate 3 and repeatedly impacts the placement plate 3, so that the prefabricated part 7 in the mold 6 falls off and lands on the elastic pad 532 of the elastic material receiving seat 53. The elastic pad 532 reduces the collision intensity between the prefabricated part 7 and the material receiving plate 531. Further, through the cooperation of the sliding rod 533 and the spring, when the prefabricated part 7 falls on the elastic pad 532, the prefabricated part 7 can be unloaded on the elastic pad 532, so that the prefabricated part 7 is not easily broken;

[0038] After demolding, start the rotary drive motor 11 again to drive the connected driving gear 122 to rotate counterclockwise for a set number of turns to reset. The driving gear 122 drives the toothed ring 124 to rotate clockwise for a set number of turns to flip the mold 6 back to its original position again, so that the open end of the mold 6 from which the prefabricated part 7 has fallen faces upward. At the same time, the driving gear 122 drives the transmission gear 52 to rotate clockwise for a set number of turns to reset, driving the first rotating shaft 511 and the driving sprocket 513 on the first rotating shaft 511 to rotate clockwise for a set number of turns, so that the chain 515 drives the elastic material receiving seat 53 to move backward to reset, so that the placement plate 3 and the elastic material receiving seat 53 are misaligned, and there is no obstruction above the elastic material receiving seat 53, which is convenient for transferring the demolded prefabricated part 7 and improves work efficiency;

[0039] The above clockwise and counterclockwise directions are determined from the right view.

[0040] The above has introduced the present utility model in detail. The description of the specific embodiments is only used to help understand the method and its core idea of the present utility model. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and modifications can still be made to the present utility model, and these improvements and modifications also fall within the protection scope of the claims of the present utility model.
