The storage hopper is disposed above the discharge platform. A control mechanism for controlling the discharge of material from the storage hopper is disposed between the storage hopper and the discharge platform. The drive arm drives the molding box on the mold feeding machine to the discharge platform or drives the molding box on the discharge platform back to the mold feeding machine.

[0008] In the preferred technical solution of the above-mentioned automated molding device for precast concrete components, the control mechanism includes a limiting plate and a laser emitter set on the limiting plate. An installation box is set on the unloading platform. The limiting plate is connected to the side of the installation box facing the mold feeding machine tool by a spring.

When the spring is in its natural state, the distance between the laser emitter and the mold feeding machine tool is less than the distance between the laser receiver and the mold feeding machine tool.

[0009] In the preferred technical solution of the above-mentioned automated molding device for precast concrete components, a power supply and an electrode plate connected to the power supply are provided in the installation box. The electrode plate is located on the side of the installation box facing the mold feeding machine tool. An electrode rod is connected to the side of the laser emitter facing the installation box. When the electrode rod contacts the electrode plate, the laser emitter emits laser light, and the laser emitter corresponds to the laser receiver.

[0010] In the preferred technical solution of the above-mentioned automated molding device for precast concrete components, the drive arm includes a hydraulic cylinder and a chuck mechanism disposed at the output end of the hydraulic cylinder. The chuck mechanism includes a chuck and a drive assembly for opening and retracting the chuck.

[0021] A specific embodiment of the automated molding device for precast concrete components according to the present invention: like Figure 1 and Figure 2 As shown, an automated molding device for precast concrete components includes a storage hopper 1, a mold feeding machine tool 2, and a discharge platform 3 and a drive arm 4 respectively disposed on the left and right sides of the mold feeding machine tool 2. The storage hopper 1 is disposed above the discharge platform 3. A control mechanism for controlling the discharge of material from the storage hopper 1 is disposed between the storage hopper 1 and the discharge platform 3. The drive arm 4 drives the molding material box 6 on the mold feeding machine tool 2 to the discharge platform 3 or drives the molding material box 6 on the discharge platform 3 back to the mold feeding machine tool 2.

[0022] like Figure 2 and Figure 3 As shown, the control mechanism includes a limit plate 31 and a laser emitter 32 mounted on the limit plate 31. A mounting box 33 is mounted on the unloading platform 3. The limit plate 31 is connected to the mounting box 33 on the side facing the mold feeding machine tool 2 via a spring 34. A laser receiver 11, a timer, and a valve are mounted on the storage hopper 1. The valve is connected to the laser receiver 11 and the timer via signals. When the spring 34 is in its natural state, the distance between the laser emitter 32 and the mold feeding machine tool 2 is less than the distance between the laser receiver 11 and the mold feeding machine tool 2.

[0023] The mounting box 33 contains a power supply and an electrode plate 35 connected to the power supply. The electrode plate 35 is located on the side of the mounting box 33 facing the mold feeding machine tool 2. The laser emitter 32 is connected to an electrode rod 36 on the side facing the mounting box 33. When the electrode rod 36 contacts the electrode plate 35, the laser emitter 32 emits laser light, and the laser emitter 32 corresponds to the laser receiver 11.

[0024] like Figure 1 and Figure 4 As shown, the drive arm 4 includes a hydraulic cylinder 41 and a chuck mechanism disposed at the output end of the hydraulic cylinder 41. The chuck mechanism includes chucks 42 and a drive assembly for opening and retracting the chucks 42. The drive assembly includes a guide sleeve 44 and a drive motor. The chucks 42 are L-shaped and symmetrically disposed on both sides of the guide sleeve 44, with the lateral portion of the chucks 42 passing through the guide sleeve 44. The drive motor is fixedly connected to the guide sleeve 44, and its output end is located between the lateral portions of the two chucks 42. A gear 43 is fixedly connected to the output end of the drive motor. A rack that meshes with the gear 43 is disposed on the chucks 42. The ends of the vertical portions of the two chucks 42 are provided with protruding edges extending toward each other.

[0025] like Figure 2 , Figure 5 and Figure 6 As shown, the storage hopper 1 is an inverted frustum shape with an open top. Three discharge ports 12 are evenly distributed around the bottom of the storage hopper 1 along its central axis. The valve includes a rotating plate 13 and a drive assembly 2 for driving the rotating plate 13 to rotate. The bottom of the rotating plate 13 is in contact with the upper bottom surface of the storage hopper 1, and the circumference of the rotating plate 13 is in contact with the inner side wall of the storage hopper 1. The rotating plate 13 is provided with through holes 14 that are adapted to the discharge ports 12.

[0026] The automated precast concrete component molding device includes a mounting frame 5. The second drive assembly includes a second drive motor 15 and a rotating shaft 16 fixedly connected to the output end of the second drive motor 15. The second drive motor 15 is mounted on the mounting frame 5. A rotating shaft 17 is fixedly connected to the center of a rotating plate 13. Stirring rods 18 are spaced along the rotating shaft 17, and the rotating shaft 17 and rotating shaft 16 are connected via a bevel gear transmission. As the stirring rods 18 rotate with the rotating shaft 17, they stir the concrete in the storage hopper 1. A mounting housing 51 is provided on the mounting frame 5. The second drive motor 15, rotating shaft 16, and bevel gear are housed within the mounting housing 51 to prevent contamination of the components when concrete is poured into the storage hopper 1, thus preventing malfunction of the components. The second drive motor 15 is connected to a laser receiver 11 and a timer signal.

[0027] The specific working process of the automated molding device for precast concrete components of the present invention is as follows: When the mold feeding machine 2 conveys the molding box 6 to the front of the drive arm 4, it stops moving; the hydraulic cylinder 41 is controlled to extend, so that the guide sleeve 44 contacts the molding box 6, and the molding box 6 is continuously pushed, so that the molding box 6 squeezes the limiting plate 31, until the electrode rod 36 on the laser emitter 32 contacts the electrode plate 35 on the power supply. At this time, the laser emitter 32 emits laser light, and after the laser receiver 11 receives the laser light, it transmits the signal to the drive motor 15 and the timer; the timer starts timing, and the drive motor 15 drives the rotating shaft 16 to rotate the rotating shaft 17 until the through hole 14 on the rotating plate 13 is aligned with the discharge port 12 at the bottom of the storage hopper 1. The concrete in the storage hopper 1 passes through the through hole 14 and the discharge port 12. The concrete is poured into the molding hopper 6. When the timer reaches the set time, it sends a signal to the second drive motor 15, which reverses and drives the through hole 14 on the rotating plate 13 to be misaligned with the discharge port 12, stopping the pouring of concrete. At this time, the claws 42 of the drive arm 4 are located on both sides of the molding hopper 6, causing the drive gear 43 of the first drive motor to rotate, driving the two claws 42 to move closer to each other, clamping the molding hopper 6. The hydraulic cylinder 41 is controlled to retract, bringing the molding hopper back to the mold feeding machine tool 2. The first drive motor is controlled to reverse, causing the two claws 42 to release the molding hopper 6. The hydraulic cylinder 41 is controlled to continue retracting, providing clearance for the continued conveying of the molding hopper 6. The mold feeding machine tool 2 is controlled to continue conveying the molding hopper 6. The above steps are repeated to complete the pouring of concrete into the molding hopper 6.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
