Description

Technical Field

[0001] This utility model relates to the field of precast concrete technology, specifically a mold for precast concrete components. Background Technology

[0002] Concrete precast molds are tools or equipment used to manufacture precast concrete components. Precast components refer to concrete components that are prefabricated outside the construction site. These components can be various types such as walls, floor slabs, beams, columns, curbs, and manhole covers. However, concrete precast molds themselves have a certain weight, and the defect rate caused by the demolding process is relatively high, so there is still room for improvement.

[0003] To address the aforementioned issues, Chinese Patent Application Publication No. CN222697493U discloses a "concrete precast component mold" composed of a first mold plate and a second mold plate. These two mold plates have good opening and closing capabilities and offer good application results. Furthermore, by applying force with a hand lever, the first and second mold plates can be aligned or disengaged along a sliding groove. The pulley assembly enhances operational efficiency and reduces labor. However, this device still has certain drawbacks in practical use. For example, during concrete precasting, a release agent needs to be applied inside the mold, but this device requires manual application of the release agent, and manual application cannot ensure even distribution. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a mold for precast concrete components, which ensures the effect by spraying components and brushing to evenly apply release agent, and hydraulic rod a drives the mold to close and separate, and the release agent makes the component come out.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: A precast concrete component mold includes: a base, on the top of which mold a and mold b are disposed, and support seats are installed on both sides of the top of the base. Hydraulic rods a are installed on the top of the support seats, and one end of each hydraulic rod a is connected to mold a and mold b respectively. A spraying assembly is disposed on the top of mold a for spraying a release agent onto the inner walls of mold a and mold b. The spraying assembly includes: a rotating block, brush a, brush b, spray ring, and spray head.

[0006] Optionally, four rotating blocks are arranged between mold a and mold b. Each of the four rotating blocks has a brush a mounted on one side of its outer end, and a brush b mounted at the bottom of each brush a. A ring-shaped spray ring is provided on the top of each rotating block, and multiple nozzles are mounted at the bottom of the spray ring. Support frames are installed on both sides of the top of the base, and a fixing plate is installed on the top of each support frame. A hydraulic rod b is installed on the top of the fixing plate, and a motor is installed at the bottom of the hydraulic rod b. Four reinforcing frames are installed between two support frames, and the bottom of the motor... A rotating rod is connected to the motor shaft for driving. Multiple drive rods are installed between the rotating rod and the four rotating blocks. A drive plate is installed at the bottom of the rotating rod. The bottom of the drive plate is connected to the brush b. A liquid storage tank is installed on one side of the top of the fixed plate. A liquid pump is installed on the top of the liquid storage tank. A delivery pipe is installed on one side of the outer end of the delivery pump. One end of the delivery pipe is connected to the spray ring. The spraying assembly consisting of the rotating blocks, brush a, brush b, spray ring and nozzle is used to spray release agent onto the inner walls of mold a and mold b.

[0007] Optionally, two locking blocks are installed on the inner sides of both mold a and mold b, and rubber blocks are installed on the inner sides of each locking block, wherein the rubber blocks are used to ensure the sealing between mold a and mold b.

[0008] The beneficial effects of this utility model are: The advantage of this utility model is that the release agent is sprayed onto the inner side of mold a and mold b through the spraying component, and then the release agent is evenly applied to the inner wall of mold a and mold b and the top of the base through brush a and brush b, thereby ensuring the release effect of the precast concrete structure. Secondly, two hydraulic rods a can drive mold a and mold b to move laterally respectively, thereby achieving precise alignment and separation of mold a and mold b. Combined with the action of the release agent, the precast concrete components can be smoothly removed. Attached Figure Description

Detailed Implementation

[0015] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0016] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0017] like Figures 1-5 As shown, a precast concrete component mold includes: a base 1, with mold a101 and mold b102 mounted on the top of the base 1, support seats 103 installed on both sides of the top of the base 1, and hydraulic rods a104 mounted on the top of the support seats 103. One end of the two hydraulic rods a104 is connected to mold a101 and mold b102 respectively. A spraying assembly is provided on the top of mold a101 for spraying a release agent onto the inner walls of mold a101 and mold b102. The spraying assembly includes: a rotating block 2, a brush a201, a brush b202, a spray ring 203, and a spray nozzle 204.

[0018] The mold consists of four rotating blocks 2 between mold a101 and mold b102. Each of the four rotating blocks 2 has a brush a201 installed on one side of its outer end. Brush b202 is installed at the bottom of brush a201. The top of the rotating blocks 2 has a ring-shaped spray ring 203. Multiple nozzles 204 are installed at the bottom of the spray ring 203. The ring-shaped spray ring 203, together with the multiple nozzles 204, can spray the release agent onto the inner wall of the mold from multiple angles, achieving initial full coverage. This, together with the rotating application of brush a201 and brush b202, forms a dual effect of spraying and wiping, ensuring that the release agent forms a complete and uniform isolation film on the mold surface, laying the foundation for subsequent smooth demolding.

[0019] The base 1 has support frames 3 installed on both sides of its top. A fixed plate 301 is installed on the top of the support frame 3. A hydraulic rod b302 is installed on the top of the fixed plate 301. A motor 303 is installed at the bottom of the hydraulic rod b302. Four reinforcing frames 304 are installed between the two support frames 3. The support frames 3 and the fixed plate 301 form a rigid support frame, providing a stable installation foundation for components such as the hydraulic rod b302 and the motor 303, and preventing the components from shaking when moving or working. The hydraulic rod b302 can drive the motor 303 and the rotating block 2, brush a201 and brush b202 connected below to move up and down, so as to achieve precise alignment of the spraying component with the inner walls of the mold a101 and mold b102. The reinforcing frames 304 enhance the connection strength between the two support frames 3, resist the lateral force generated by the downward movement of the components or the operation of the motor 303, prevent the support frame 3 from deforming, and ensure the stability and safety of the entire spraying component adjustment process.

[0020] The motor 303 has a rotating rod 4 connected to its bottom via a motor shaft. Multiple drive rods 401 are installed between the rotating rod 4 and the four rotating blocks 2. A drive disk 402 is installed at the bottom of the rotating rod 4, and the bottom of the drive disk 402 is connected to the brush b202. The rotational power of the motor 303 is transmitted through the rotating rod 4 and then distributed to the four rotating blocks 2 via the drive rods 401, so that the four rotating blocks 2 rotate synchronously. This ensures that the brush a201 applies uniform pressure and coverage to the mold sidewall. The drive disk 402 at the bottom of the rotating rod 4 is directly connected to the brush b202, causing the brush b202 to rotate synchronously, achieving uniform application of the release agent to the top of the base 1. This works in conjunction with the brush a201 on the sidewall to cover all contact surfaces.

[0021] The fixed plate 301 has a liquid storage tank 5 installed on one side of its top. A pump 501 is installed on the top of the liquid storage tank 5. A delivery pipe 502 is installed on one side of the outer end of the pump 501. One end of the delivery pipe 502 is connected to the spray ring 203. The liquid storage tank 5 is used to store the release agent. An injection pipe is installed on one side of the top of the liquid storage tank 5 to inject the release agent into the liquid storage tank 5. The pump 501 pressurizes the release agent in the liquid storage tank and delivers it to the spray ring 203 through the delivery pipe 502, providing a stable liquid pressure to ensure that the nozzle 204 can spray the release agent evenly and continuously. The delivery pipe 502 is made of a flexible hose, so the delivery pipe 502 will not affect the lifting and lowering of the entire spraying assembly.

[0022] Both molds a101 and b102 have two locking blocks 6 installed on their inner sides, and rubber blocks 601 are installed on the inner side of each locking block 6. When molds a101 and b102 are aligned, the two locking blocks 6 interlock with each other, playing a mechanical positioning role. This ensures that the molds are accurately positioned during alignment and avoids dimensional deviations in the precast components due to misalignment. The rubber blocks 601 on the inner side of the locking blocks are elastic and are squeezed and deformed when the molds are aligned, filling the gap between the locking blocks 6 and the molds to achieve a secondary seal. Together with the mating surface of the molds themselves, they form a completely sealed casting cavity, effectively preventing grout leakage during concrete pouring and ensuring the appearance quality and structural integrity of the precast components.

[0023] Working principle: When using this device, first activate the hydraulic rod a104 to drive the molds a101 and b102 to precisely align on the base 1. At this time, the locking blocks 6 inside the molds a101 and b102 interlock with each other, and the rubber blocks 601 inside the locking blocks 6 fit tightly together to form a sealed pouring cavity, preventing grout leakage during subsequent pouring. Next, the hydraulic rod b302 is activated, pushing the motor 303 downward. The motor 303 drives the rotating rod 4, the driving rod 401, the rotating block 2 and other related structures to move downward synchronously until the brush a201 at the outer end of the rotating block 2 and the brush b202 at the bottom are in a suitable position that can fit against the inner wall of the mold a101 and the mold b102. The fixing plate 301 and the support frame 3 provide stable support for the components in this process, while the reinforcing frame 304 enhances the connection strength between the two support frames 3. Next, the release agent in the storage tank 5 is delivered to the spray ring 203 through the delivery pipe 502 by the pump 501. Then, it is evenly sprayed onto the inner walls of mold a101 and mold b102 through multiple nozzles 204 at the bottom of the spray ring 203. At the same time, the motor 303 drives the rotating rod 4 to rotate. The rotating rod 4 drives the four rotating blocks 2 to rotate synchronously through the drive rod 401. The brush a201 at the outer end of the rotating block 2 and the brush b202 at the bottom rotate accordingly, further spreading the release agent sprayed on the inner walls of mold a101 and mold b102 and the top of the base 1 evenly, preparing for subsequent demolding. After the release agent is applied, the well-mixed concrete mixture is poured into the casting cavity formed by the mating of molds a101 and b102 until the preset pour volume is reached, and then the concrete is allowed to solidify. Under suitable curing conditions, the concrete gradually solidifies and hardens within the mold, forming a precast component that conforms to the design shape. Once the concrete strength reaches the demolding requirement, the hydraulic rod a104 is activated again to separate molds a101 and b102. At this point, the precast component is successfully separated from the inner walls of molds a101 and b102 due to the previously applied release agent, thus completing the entire molding process of the precast concrete component.
