Abstract

This utility model relates to the field of mold technology, and specifically discloses a mold for making building components based on inorganic non-metallic materials. The mold includes an upper mold, a lower mold, and a base. The lower mold is fixedly installed on the base. A mold cavity is formed inside the lower mold, and an annular groove is formed in the inner wall of the mold cavity. A liner plate is placed inside the annular groove. The liner plate is made of hard alloy material with a hardness close to diamond and extremely high wear resistance, capable of withstanding high-frequency, high-intensity aggregate impacts. A sealing ring and a water-absorbing strip are fixedly installed on the side wall of the liner plate, with the water-absorbing strip located below the sealing ring. Both the sealing ring and the water-absorbing strip are internally located within the annular groove.

This device uses a highly wear-resistant liner plate to directly withstand the impact and friction of hard aggregates, replacing traditional easily worn materials such as steel and cast iron that directly contact the material, thus reducing scratches and grooved wear on the inner wall of the mold cavity caused by continuous friction from the source.

Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for making building components based on inorganic non-metallic materials. Background Technology

[0002] In the process of industrialized construction, cement-based materials containing hard aggregates (such as recycled aggregate concrete, steel fiber concrete, and high-strength crushed stone concrete) are widely used in the production of precast composite slabs, assembled beams and columns, and decorative wall panels due to their advantages of high strength, high durability, and resource recycling. These materials typically contain hard aggregates of different particle sizes (such as quartz sand, basalt crushed stone, and steel slag, which have high Mohs hardness). During the pouring, vibration, and molding processes, the continuous contact between the aggregates and the inner surface of the mold can cause severe friction, becoming a key issue restricting production efficiency and component quality.

[0003] Existing molds are mostly made of steel, cast iron, or ordinary stainless steel, whose surface hardness is much lower than that of hard aggregates. Now, before starting the machine every day, it is necessary to squat down and check the condition of the molds. Although the surface of the molds made of steel, cast iron, or ordinary stainless steel may look flat, you can tell something is wrong just by touching it. When vibrating, you can feel the aggregate hitting the mold. After multiple production batches, scratches gradually appear on the inner wall of the mold cavity. Initially, they are fine lines, but as the number of production batches increases, they evolve into grooved wear. The surface roughness of some areas increases significantly. When dismantling the mold, you can see that the surface of the component has formed pitting and scratches. Sometimes, metal fragments generated by mold wear are attached, resulting in the component's appearance quality not meeting the standards. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a mold for manufacturing building components based on inorganic non-metallic materials. It solves the technical problem that existing molds made of steel, cast iron, or ordinary stainless steel have a lower surface hardness than hard aggregates. During vibration, the mold cavity is subjected to continuous impact and sliding friction from the aggregates, resulting in scratches, grooved wear, and increased roughness on the inner wall after multiple batches of production. This leads to pitted surfaces, scratches, and possible metal debris adhering to the component surface, resulting in substandard appearance quality.

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

[0006] A mold for manufacturing building components based on inorganic non-metallic materials includes an upper mold, a lower mold, and a base. The lower mold is fixedly installed on the base. The lower mold has a cavity inside, and an annular groove is formed in the inner wall of the cavity. A liner is placed inside the annular groove. A sealing ring and a water-absorbing strip are fixedly installed on the side wall of the liner. The water-absorbing strip is located below the sealing ring. Both the sealing ring and the water-absorbing strip are internally disposed in the annular groove. A rubber pad is fixedly installed at the lower end of the liner. The lower end of the rubber pad has a strip-shaped groove. The liner replaces traditional easily worn materials such as steel and cast iron in direct contact with the material, thereby reducing scratches and grooved wear on the inner wall of the mold cavity caused by continuous friction from the source.

[0007] Preferably, a screw is fixedly installed at the lower end of the liner, the screw is disposed inside the lower mold, a nut is threaded onto the screw, limit grooves are formed on the opposite ends of the two vertical blocks, a sliding column is slidably installed inside the lower mold, a limit plate is fixedly installed at the lower end of the sliding column, the limit plate is rotatably installed in the two limit grooves, a connecting groove is formed inside the sliding column, a turntable is rotatably installed on the limit plate, a spring is fixedly installed at the upper end of the turntable, and the upper end of the spring is fixedly connected to the lower mold, which greatly reduces the demolding resistance and thus ensures the integrity of demolding.

[0008] Preferably, the rubber pad is fixedly installed with a first magnetic block at both ends, and a second magnetic block is symmetrically arranged in the inner wall of the mold cavity. The two second magnetic blocks are respectively installed with the two first magnetic blocks. When disassembling, it can be easily separated by overcoming the magnetic force, which facilitates the individual replacement and maintenance of the rubber pad.

[0009] Preferably, a retaining ring is fixedly installed in the inner wall of the mold cavity, and a retaining groove is fixedly installed on the surface of the liner. The retaining groove and the retaining ring are engaged together. During installation, the installation status can be intuitively confirmed by the tactile feeling or sound of the retaining ring being engaged. The operation is simple and the connection is reliable.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] This equipment uses a high-wear-resistant liner to directly withstand the impact and friction of hard aggregates, replacing traditional easily worn materials such as steel and cast iron that directly contact the material. This reduces scratches and grooved wear on the inner wall of the mold cavity caused by continuous friction from the source. At the same time, the liner adopts a detachable design. When wear occurs in a local area, there is no need to disassemble the entire mold or shut down for major repairs. The liner can be quickly replaced individually, which greatly shortens the maintenance time and reduces the total life cycle cost of the mold. Attached Figure Description

[0023] This application provides a mold for manufacturing building components based on inorganic non-metallic materials, which effectively solves the problem that existing molds made of steel, cast iron, or ordinary stainless steel have a lower surface hardness than hard aggregates. During vibration, the mold cavity is subjected to continuous impact and sliding friction from the aggregates, resulting in scratches, grooved wear, and increased roughness on the inner wall after multiple batches of production. This leads to pitting, scratches, and possible metal debris adhering to the surface of the components, resulting in substandard appearance quality.

[0024] Example 1: As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the technical solution in this application effectively solves the technical problem that existing molds made of steel, cast iron, or ordinary stainless steel, due to their lower surface hardness than hard aggregates, suffer from scratches, grooved wear, and increased roughness on the inner wall of the mold cavity after multiple batches of production due to continuous impact and sliding friction from the aggregates during vibration. This results in pitted surfaces, scratches, and possible metal debris adhering to the component surface, leading to substandard appearance quality. The overall concept is as follows: A mold for making building components based on inorganic non-metallic materials includes an upper mold 1, a lower mold 2, and a base 3. The lower mold 2 is fixedly installed on the base 3. A mold cavity 4 is opened inside the lower mold 2. An annular groove 5 is opened in the inner wall of the mold cavity 4. A liner 6 is placed inside the annular groove 5. The liner 6 is made of hard alloy material with a hardness close to diamond and extremely strong wear resistance, capable of withstanding high frequency and high pressure. To withstand strong aggregate impact, a sealing ring 7 and a water-absorbing strip 8 are fixedly installed on the side wall of the liner 6. The water-absorbing strip 8 is located below the sealing ring 7. Both the sealing ring 7 and the water-absorbing strip 8 are internally located in the annular groove 5. When the liner 6 is installed, the sealing ring 7 will seal the connection between it and the lower mold 2, effectively preventing material from penetrating into the connection gap between the two and causing adhesion problems. In addition, the elastic deformation of the sealing ring 7 can compensate for the installation error between the liner 6 and the annular groove 5, ensuring that the surface of the liner 6 is flush with the inner wall of the mold cavity, avoiding defects such as flash and dents on the surface of the component due to the stepped gap. During the curing process, inorganic non-metallic materials will release free water. If it seeps into the gap of the annular groove 5, it will cause the metal mold to rust and the liner 6 to become damp and deformed. The water-absorbing strip 8 can quickly absorb the moisture, keep the annular groove dry, and reduce the corrosion rate of the mold.

[0025] A rubber pad 9 is fixedly installed at the lower end of the liner 6. A strip groove 10 is opened at the lower end of the rubber pad 9. The rubber pad 9 itself has a moderate hardness of Shore 60-70A, which can absorb the impact force when the liner is installed through its own deformation, and avoid the deformation of the liner or mold cavity caused by rigid contact.

[0026] Enhanced air friction of the strip groove 10: When the rubber pad 9 is compressed or vibrates, the air in the strip groove 10 will flow in a directional manner due to the constraint of the groove wall. The friction between the airflow and the groove wall forms a damping force, which further attenuates the vibration energy.

[0027] like Figure 3 , Figure 5 and Figure 6As shown, a screw 11 is fixedly installed at the lower end of the liner 6. The screw 11 is located inside the lower mold 2. A nut 12 is threaded onto the screw 11. Limiting grooves 15 are opened on the opposite ends of the two vertical blocks 14. A sliding column 16 is slidably installed inside the lower mold 2. A limiting plate 17 is fixedly installed at the lower end of the sliding column 16. The limiting plate 17 is rotatably installed in the two limiting grooves 15. A connecting groove 18 is opened inside the sliding column 16. A turntable 19 is rotatably installed on the limiting plate 17. A spring 20 is fixedly installed at the upper end of the turntable 19. The spring 20 is initially in a stretched state. Fixedly connected to the lower mold 2, when the mold is removed, a vacuum adsorption effect will be formed in the mold cavity of the liner 6. The suction force makes it difficult for the mold to be demolded. The limiting plate 17 can be rotated on the turntable 19. At this time, the limiting plate 17 will slide out from the two limiting grooves 15. When the limiting plate 17 loses the support of the two vertical blocks 14, the spring 20 will return to the contracted state. As the molding mold moves upward during demolding, the sliding column 16 will move upward accordingly. When the connecting groove 18 on the sliding column 16 connects with the mold cavity inside the liner 6, the vacuum adsorption will be broken, which will greatly reduce the demolding resistance and thus ensure the integrity of demolding.

[0028] Example 2: As Figure 7 and Figure 8 As shown, first magnetic blocks 21 are fixedly installed at both ends of the rubber pad 9, and second magnetic blocks 22 are symmetrically arranged in the inner wall of the mold cavity 4. The two second magnetic blocks 22 are respectively installed in correspondence with the two first magnetic blocks 21. Based on embodiment 1, the column groove 13 and the vertical block 14 are replaced with the first magnetic blocks 21 and the second magnetic blocks 22. During installation, the two first magnetic blocks 21 on the liner 6 can be aligned with the two second magnetic blocks 22 inside the mold cavity 4, and the liner 6 and the lower mold 2 can be installed by magnetic attraction.

[0029] Example 3: As Figure 9 As shown, a retaining ring 23 is fixedly installed in the inner wall of the mold cavity 4, and a retaining groove 24 is fixedly installed on the surface of the liner 6. The retaining groove 24 and the retaining ring 23 are engaged together. Based on embodiment 1, the column groove 13 and the vertical block 14 are replaced with the retaining ring 23 and the retaining groove 24. During installation, the liner 6 can be pressed into the mold cavity 4. At this time, the retaining ring 23 will slightly deform and spring into the retaining groove 24 to form a snap-fit, thus completing the installation.

[0030] To address the problems existing in the prior art, this utility model provides a mold for making building components based on inorganic non-metallic materials. The equipment uses a high wear-resistant liner to directly bear the impact and friction of hard aggregates, replacing the direct contact of easily worn materials such as traditional steel and cast iron with materials, thereby reducing scratches and grooved wear on the inner wall of the mold cavity caused by continuous friction from the source.

[0031] Working principle:

[0032] First, when using the liner 6, insert the screw 11 on the liner 6 into the lower mold 2, and then rotate the nut 12 on the screw 11 to complete the installation of the liner 6. At this time, the sealing ring 7 and the water-absorbing strip 8 on the liner 6 will also be attached to the annular groove 5, and the rubber pad 9 will be pressed against the lower end of the mold cavity 4. Inorganic non-metallic material can be injected into the mold cavity of the liner 6. Then, the upper mold 1 and the lower mold 2 are closed by hydraulic components. After cooling, the mold can be removed.

[0033] In the second step, when the mold is removed, a vacuum adsorption effect will be formed in the mold cavity of the liner plate 6. The suction force makes it difficult for the mold to be demolded. The limiting plate 17 can be rotated on the turntable 19. At this time, the limiting plate 17 will slide out from the two limiting grooves 15. When the limiting plate 17 loses the support of the two vertical blocks 14, the spring 20 will return to the contracted state. As the molding mold moves upward during demolding, the sliding column 16 will move upward accordingly. When the connecting groove 18 on the sliding column 16 connects with the mold cavity inside the liner plate 6, the vacuum adsorption will be broken, which will greatly reduce the demolding resistance and thus ensure the integrity of demolding.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
