Description

Technical Field

[0001] The invention relates to the technical field of concrete precast slab manufacturing, and in particular to a concrete precast slab manufacturing and demolding device. Background Art

[0002] In the field of construction, concrete precast panels are widely used in various construction projects due to their high efficiency and economic characteristics. The production process of precast panels involves steps such as mold preparation, concrete pouring, maintenance and demolding, among which demolding is an important link to ensure the quality and production efficiency of precast panels. However, the existing concrete precast panel production and demolding devices, whether manually operated or on the production line, usually use the method of inverted molds to invert the precast panels. This method has many significant disadvantages in practical applications, especially it is easy to cause cracks, breakage or other forms of damage to the precast panels.

[0003] During the demoulding process, the impact force and gravity on the precast panels may cause cracks on their surface or edges. This is because the precast panels need to be quickly separated from the mold during the inversion. This rapid separation process will produce instantaneous stress concentration, especially at the edges and weak parts of the precast panels, which are more likely to crack. This risk is more prominent for precast panels with low strength or insufficient curing time.

[0004] Inverted demoulding may also cause physical damage to prefabricated panels. During the inverted demoulding process, the prefabricated panels may collide with the mold or other hard objects, especially when multiple prefabricated panels are demoulded at the same time. The mutual squeezing and friction between them can easily lead to surface scratches, dents and other problems. These damages not only affect the appearance of the prefabricated panels, but may also weaken their structural strength and reduce their safety in use.

[0005] Since undercut mold removal requires a large space to operate, this limits the layout flexibility of the production line to a certain extent. Especially in a production environment with limited space, it may take extra time and manpower to arrange the mold removal operation, thus affecting the overall production efficiency. In addition, frequent undercut operations may also accelerate the wear of the mold and increase maintenance costs.

[0006] The inverted demoulding method is not suitable for some special shapes or large prefabricated panels. For example, for curved or special-shaped prefabricated panels, inverted demoulding may cause shape deformation and affect the final installation effect. For heavy prefabricated panels, there are more unstable factors in the inverted process and higher safety risks.

[0007] From the perspective of environmental protection, the damaged prefabricated panels produced during the process of removing the molds need to be treated as waste, which not only wastes raw materials but also increases the burden of handling construction waste. With the popularization of the concept of green building, reducing resource waste and environmental pollution in the production process has become an important trend in the development of the industry.

[0008] In summary, the existing concrete precast panel production and demolding device has obvious disadvantages of easily causing cracks, breakage and other damages to the precast panels when the inverted mold is used for demolding. These problems not only affect the product quality of the precast panels, but also increase production costs and reduce production efficiency.

[0009] Therefore, how to provide a concrete precast panel production and demolding device is a problem that technical personnel in this field urgently need to solve. Summary of the invention

These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0038] In the field of construction, concrete precast panels are widely used in various construction projects due to their high efficiency and economy. The production process of precast panels involves steps such as mold preparation, concrete pouring, maintenance and demolding, among which demolding is an important link to ensure the quality and production efficiency of precast panels. However, the existing concrete precast panel production and demolding devices, whether manually operated or on the production line, usually use the inverted mold method to invert the precast panels. This method has many significant disadvantages in practical applications, especially it is easy to cause cracks, breakage or other forms of damage to the precast panels.

[0039] During the process of demoulding, the impact force and gravity applied to the precast panels may cause cracks on their surface or edges. This is because the precast panels need to be quickly separated from the mold during the inversion. This rapid separation process will produce instantaneous stress concentration, especially at the edges and weak parts of the precast panels, which are more prone to cracking. This risk is more prominent for precast panels with lower strength or insufficient curing time.
