[0031] The present invention will be further explained below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0032] Please see Figure 1-6A recycled plastic concrete component molding equipment includes a support frame 1, with a quantitative feeding component 2 installed on the top of the support frame 1. A lifting frame 3 is vertically slidably mounted on the support frame 1. A set of flip-hanging brackets 4 are respectively provided at both ends of the lifting frame 3, and the flip plates 402 of the two sets of flip-hanging brackets 4 jointly hold the mold 10. Several sets of support components 5 are provided below each set of flip-hanging brackets 4 to control the rotation of the flip plates 402. The lifting frame 3 is also equipped with several sets of vibration components 6 that move with the lifting frame 3. In the embodiment shown in the attached drawing, a set of vibration components 6 is provided at both ends of the lifting frame 3. Screws 7 are threadedly connected to both ends of the lifting frame 3. One end of each screw 7 is coaxially connected to a second drive motor 8, and the other end of each screw 7 is rotatably connected to a fixed seat 9 fixedly connected to the support frame 1. The second drive motor 8 is fixedly connected to the side wall of the support frame 1, and the screw 7 is rotatably connected to the fixed seat 9 through bearings. When applied in a production line, the bottom of the support frame 1 passes laterally through a conveyor belt with a width smaller than the length of the mold 10. The conveyor belt can also be equipped with a vibration device to assist in removing air bubbles from the concrete slurry.

[0033] The quantitative feeding assembly 2 includes a feeding hopper 201 fixedly installed on the top of the support 1. Several discharge ports extending from the bottom of the feeding hopper 201 correspond to several compartments of the mold 10, and each discharge port is rotatably mounted with an impeller 203. All impellers 203 are rotatably connected to a drive shaft 202, one end of which is coaxially connected to a first drive motor 204 installed on one side of the support 1. A bearing is coaxially fitted at each end of the drive shaft 202, and both bearings are embedded in the vertical plate of the support 1. The first drive motor 204 and the second drive motor 8 are stepper motors or servo motors, capable of precisely controlling the rotation angle.

[0034] The lifting frame 3 includes two side frames 301 that are slidably connected to the vertical plates on both sides of the support 1. A connecting plate 302 is slidably connected to both side frames 301. Fixing bolts 303 are threaded to both ends of the connecting plate 302, and the fixing bolts 303 pass through straight grooves on the side frames 301 that are perpendicular to the connecting plate 302. Loosening the fixing bolts 303 adjusts the relative position between the connecting plate 302 and the two side frames 301, accommodating molds 10 of different widths.

[0035] Each set of flip-up brackets 4 includes a fixed plate 401 fixedly connected to the lifting frame 3, and the fixed plate 401 is horizontally rotatably connected to the flip plate 402. The top of the fixed plate 401 is covered by a cover plate 404 that covers the gap between the fixed plate 401 and the flip plate 402. The cover plate 404 does not affect the flip plate 402 from rotating from horizontal to vertical, and is used to prevent impurities from falling onto the support assembly 5 and affecting the operation of the support assembly 5. A limit block 403 is installed on the top of one end of the flip plate 402 near the lateral opening of the lifting frame 3 to prevent the flip plate 402 from slipping off the mold 10 when it vibrates.

[0036] Each support assembly 5 includes a fixed frame 501 fixedly connected to the lifting frame 3, and a support block 502 adapted to the flip plate 402 is horizontally slidably connected to the fixed frame 501. A spring 503 is installed inside the fixed frame 501, with its two ends respectively abutting against the fixed frame 501 and the support block 502, and the support block 502 abuts against the bottom of the flip plate 402. A pressing rod 504 for pressing the support block 502 away from the flip plate 402 is installed at the bottom of the bracket 1. The top of the pressing rod 504 is provided with an inclined surface for pressing, and the support block 502 is provided with an inclined surface adapted to the pressing of the pressing rod 504.

[0037] Each vibration assembly 6 includes a mounting base 601 fixedly connected to the lifting frame 3, and a mounting shaft 602 is rotatably mounted on the mounting base 601. A bearing is coaxially fixedly sleeved on the mounting shaft 602, and the bearing is embedded in the mounting base 601. A gear 603 is coaxially fixedly connected to the mounting shaft 602, and an eccentric wheel 604 is also fixedly sleeved on the mounting shaft 602. A rack 605 is vertically embedded in the bracket 1 for meshing with the gear. As the lifting frame 3 rises and falls, the gear 603 is driven to rotate by the rack 605. The gear 603 drives the eccentric wheel 604 to rotate via the mounting shaft 602, thereby generating vibration, which causes air bubbles in the uncured concrete slurry within the mold 10 to be dislodged.

[0038] Working principle:

[0039] During operation, mixed concrete slurry is added to the feeding hopper 201. The mold 10 is placed between the two sets of tilting hangers 4, with two flip plates 402 hooking onto both sides of the mold 10. The connecting plate 302 and the limiting block 403 restrict the mold 10's horizontal movement. Then, the second drive motor 8 drives the lifting frame 3 to its highest position via the screw 7. The discharge port of the feeding hopper 201 approaches the cavity of the mold 10. The first drive motor 204 drives the impeller 203 to rotate at a specified angle via the drive shaft 202 for quantitative feeding. The maximum feeding accuracy is the amount of concrete slurry stored between two adjacent blades of the impeller 203. After a fixed amount of concrete slurry is added to the cavity of the mold 10, the second drive motor 8... The lifting frame 3 is driven by screw 7 to descend slowly. During the descent, gear 603 is driven to rotate by rack 605. Gear 603 drives eccentric wheel 604 to rotate through mounting shaft 602, thereby generating vibration. This causes air bubbles in the uncured concrete slurry inside mold 10 to be shaken out. When the lifting frame 3 is lowered to the lowest point, extrusion rod 504 extrudes support block 502 to completely detach from flap 402. Under the gravity of flap 402 and mold 10, flap 402 rotates to vertical. Mold 10 falls a short distance, detaches from lifting frame 3, and lands on conveyor belt. Finally, mold 10 is transported to the designated position. The vibration generated when mold 10 lands on conveyor belt also helps to expel air bubbles in concrete slurry.

[0040] This application applies to the production of lightweight concrete components with the addition of recycled plastics as part of the aggregate, resulting in concrete component blocks with low density.
