Abstract

This utility model provides a mold fixing device for small recycled concrete components, belonging to the field of precast components. It includes an equipment platform with a clamping mechanism for fixing the mold, a pressing component to prevent the mold from tipping over, and a demolding component to facilitate mold removal. Through the clamping mechanism and pressing component, the two clamping plates move relative to each other via a bidirectional lead screw and guide rod, stably clamping molds of different sizes. This solves the problems of easy stripping and loosening of bolt connections and avoids grout leakage at mold joints. The electric push rod of the pressing component pushes the pressure head to press the mold from above, avoiding the uneven force that can easily cause mold stress imbalance under traditional manual binding. It applies uniform pressure from the vertical direction, preventing the mold from tipping over or deforming under the lateral pressure of the recycled concrete.

Description

Technical Field

[0001] This utility model relates to the field of precast components, and more specifically, to a mold fixing device for small recycled concrete components. Background Technology

[0002] With the sustainable development of the construction industry, recycled concrete has been widely used in the production of small components in municipal engineering, landscaping, and road ancillary facilities due to its advantages such as resource recycling and reduced construction waste. These components include curb stones, manhole covers, and grass pavers. These small components are characterized by diverse specifications, large production batches, and relatively complex shapes. Their molding quality directly affects the safety and durability of engineering structures.

[0003] Currently, the mold fixing devices commonly used in the production of small recycled concrete components mostly employ traditional methods such as bolt connections, clip fastening, or manual binding. Due to the uneven aggregate gradation and differences in fluidity between recycled concrete and ordinary concrete, significant lateral pressure is easily generated during the molding process. Traditional fixing devices often suffer from thread stripping after repeated loading and unloading of bolt connections, and clip structures are prone to deformation and loosening under lateral forces, leading to grout leakage at the mold joints. Therefore, a mold fixing device for small recycled concrete components is proposed. Utility Model Content

[0004] The purpose of this utility model is to address the problems in the current mold fixing devices commonly used in the production of small recycled concrete components, which mostly employ traditional methods such as bolt connections, buckle fastening, or manual binding. Due to the uneven aggregate gradation and different fluidity of recycled concrete compared to ordinary concrete, it is prone to generating large lateral pressure during the molding process. Traditional fixing devices often suffer from problems such as thread stripping after repeated loading and unloading of bolt connections, and deformation and loosening of buckle structures under lateral forces, leading to grout leakage at the mold joints. This utility model provides a mold fixing device for small recycled concrete components to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0024] Therefore, the following detailed description of the embodiments of this utility model is not intended to limit the scope of the claimed utility model, but merely to illustrate some embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0025] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0026] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0027] like Figure 1 As shown, this embodiment proposes a mold fixing device for small recycled concrete components, including an equipment platform 1, a clamping mechanism 2 for fixing the mold is provided on the top of the equipment platform 1, a pressing component 3 for preventing the mold from tipping over is provided on the top of the equipment platform 1, and a demolding component 4 for facilitating the demolding of the mold is provided on the top of the equipment platform 1.

[0028] like Figure 2 and Figure 4 As shown, the clamping mechanism 2 includes a fixed block 201 disposed on the top of the equipment platform 1. Two fixed blocks 201 are disposed opposite to each other. A bidirectional lead screw 202 and a guide rod 203 are disposed between the two fixed blocks 201. The fixed blocks 201 provide support for the bidirectional lead screw 202. The bidirectional lead screw 202 passes through the fixed blocks 201 and is rotatably connected to the fixed blocks 201. A rotary motor 204 is bolted to one end of the bidirectional lead screw 202 that passes through the fixed blocks 201. The rotary motor 204 provides stable clamping speed and force. A clamping plate 205 is disposed outside the bidirectional lead screw 202. Two clamping plates 205 are disposed opposite to each other. The guide rod 203 passes through the clamping plate 205 and the bidirectional lead screw 202 to ensure that the clamping plates 205 move synchronously, avoid mold force deviation, and ensure clamping symmetry. Anti-slip pads 206 are disposed on the side walls of the two clamping plates 205 to avoid mold wear caused by hard contact between the clamping plates 205 and the mold. When in use, the rotating motor 204 starts and drives the bidirectional lead screw 202 to rotate, which in turn drives the two clamping plates 205 to move in opposite directions or away from each other along the axis of the lead screw. The anti-slip pads 206 on the side walls of the clamping plates 205 directly contact the mold, thereby increasing the friction of the contact surface to prevent the mold from sliding in the clamped state.

[0029] like Figure 4 and Figure 5As shown, an L-shaped bracket 301 is installed on the top of the equipment platform 1, and an electric push rod 302 is mounted on the top of the L-shaped bracket 301. The electric push rod 302 can precisely control the downward stroke and force. A pressure head 303 is installed at the end of the electric push rod 302 near the equipment platform 1, and a rubber pad 304 is installed at the end of the pressure head 303 near the equipment platform 1. The elastic cushioning of the rubber pad 304 can prevent the pressure head 303 from rigidly squeezing the top of the mold and protect the edge of the mold. In use, the L-shaped bracket 301 provides fixed support for the electric push rod 302. When the electric push rod 302 extends or retracts, it drives the pressure head 303 to rise and fall vertically. When the mold is clamped, the electric push rod 302 extends, causing the pressure head 303 to press down to the top of the mold. The vertical pressure prevents the mold from tipping over during casting or vibration. The rubber pad 304 is located between the pressure head 303 and the mold, and buffers the pressure through elastic deformation.

[0030] like Figure 2 As shown, the demolding assembly 4 includes an atomizing nozzle 401 mounted on top of an L-shaped bracket 301. A pipe 402 is connected to the end of the atomizing nozzle 401 furthest from the equipment platform 1, and a release agent storage tank 403 is connected to the end of the pipe 402 furthest from the atomizing nozzle 401. In use, the release agent in the storage tank 403 is delivered to the atomizing nozzle 401 via the pipe 402. The nozzle atomizes the release agent and sprays it evenly onto the inner wall of the mold, forming a separating film between the concrete and the mold, reducing adhesion. This method is more efficient than manual application and reduces release agent waste, facilitating subsequent demolding.

[0031] like Figure 5 As shown, pressure sensors 5 are installed on the side wall of the clamping plate 205 and the bottom of the pressure head 303. The pressure sensors 5 are electrically connected to the rotating motor 204 and the electric push rod 302, respectively. In use, the pressure sensors 5 detect the lateral pressure of the clamping plate 205 on the mold and the vertical pressure of the pressure head 303 on the mold in real time, and convert the pressure signal into an electrical signal and transmit it to the control system of the rotating motor 204 and the electric push rod 302. When the pressure reaches the preset threshold, the system automatically stops the motor and push rod.

[0032] like Figure 1 As shown, the top of the equipment platform 1 is provided with a waste recycling port 6, and the bottom of the two waste recycling ports 6 is provided with a waste collection box 7. During use, the concrete slurry overflowing during the pouring process, the debris falling off during demolding, and other waste materials fall directly into the waste collection box 7 at the bottom through the waste recycling port 6 at the top of the equipment platform 1, so as to achieve centralized collection and avoid the accumulation of waste on the equipment platform 1 and affect subsequent operations.

[0033] like Figure 4As shown, a control panel 9 is installed on the top of the equipment platform 1, and a vibrating motor 8 is bolted to the bottom of the equipment platform 1. The vibrating motor 8 is electrically connected to the control panel 9. In use, the control panel 9 integrates control buttons for each component. The operator sets parameters through the panel. The vibrating motor 8 is connected to the equipment platform 1. After being powered on, it generates vibration and transmits it to the mold, making the concrete inside the mold compact and expelling air bubbles.

[0034] like Figure 1 As shown, the top of the equipment platform 1 is provided with an anti-stick coating, which is made of polytetrafluoroethylene (PTFE) coating. In use, the PTFE coating is applied to the top surface of the equipment platform 1. Utilizing its extremely low surface energy and non-stick properties, it prevents fallen concrete debris and slurry from adhering to the surface of the equipment platform 1.

[0035] Specifically, when using the mold fixing device for this recycled concrete small component: First, the release agent in the release agent storage tank 403 is transported to the atomizing nozzle 401 through the pipe 402. The nozzle atomizes the release agent and sprays it evenly onto the inner wall of the mold, forming a release film between the concrete and the mold, reducing adhesion. This is more efficient than manual application and reduces release agent waste, facilitating subsequent demolding (e.g., Figure 2 (As shown), after the rotating motor 204 starts, it drives the bidirectional lead screw 202 to rotate, which in turn drives the two clamping plates 205 to move in opposite directions or away from each other along the lead screw axis. The anti-slip pads 206 on the side walls of the clamping plates 205 directly contact the mold, increasing the friction of the contact surface to prevent the mold from sliding in the clamped state (e.g., Figure 2 and Figure 4 As shown), the L-shaped bracket 301 provides fixed support for the electric push rod 302. When the electric push rod 302 extends or retracts, it drives the pressure head 303 to rise and fall vertically. When the mold is clamped, the electric push rod 302 extends, causing the pressure head 303 to press down to the top of the mold. The vertical pressure prevents the mold from tipping over during casting or vibration. The rubber pad 304 is located between the pressure head 303 and the mold, and buffers the pressure through elastic deformation (e.g., ...). Figure 4 and Figure 5 As shown), pressure sensor 5 detects in real time the lateral pressure of clamping plate 205 on the mold and the vertical pressure of pressure head 303 on the mold, and converts the pressure signal into an electrical signal, which is transmitted to the control system of rotary motor 204 and electric push rod 302. When the pressure reaches a preset threshold, the system automatically stops the motor and push rod (as shown). Figure 5 As shown), the control panel 9 integrates control buttons for each component. Operators set parameters via the panel. The vibration motor 8 is connected to the equipment platform 1; after being powered on, it generates vibration and transmits it to the mold, compacting the concrete inside and expelling air bubbles (such as...). Figure 4 (As shown).

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
