Description

Technical Field

[0001] The utility model relates to the technical field of prefabricated concrete components, in particular to a combined mould for prefabricated concrete components. Background Art

[0002] At present, cast-in-place concrete construction methods are widely used in the field of construction engineering. However, due to the problems of long construction period, high resource consumption and environmental pollution, concrete precast component technology has been increasingly adopted in recent years. The application of this technology not only effectively improves construction efficiency and shortens construction period, but also significantly reduces safety hazards and environmental impacts on construction sites. However, the molds currently used in the market for the production of concrete precast components generally have the problems of high degree of customization and poor versatility, resulting in high mold costs and difficulty in cross-project reuse.

[0003] Traditional mold design solutions mainly include two forms: integral fixed molds and simple disassembly molds. Although the former has higher molding quality, in actual application, due to its non-disassembly characteristics, the mold can only be made for components of specific shapes and sizes. Once the project is completed, it almost loses its value for reuse. The latter achieves a certain degree of flexible assembly and adjustment through modular design, but is limited by the connection complexity and precision requirements between individual modules. Its scope of application is still relatively limited, and wear after long-term use will lead to a decline in mold performance. Although these two types of molds can meet basic production needs, they cannot fundamentally solve the problems of mold reusability and economic benefits.

[0004] After searching, the Chinese patent announcement number: CN211164522U discloses a vertical combination mold for the production of precast concrete components, including a vertical mold body, two vertical modules are arranged in the vertical mold body, L-shaped blocks are fixed on both sides of the two vertical modules, scale bars are fixed on both sides of the upper end of the vertical mold body, one side of the L-shaped block is provided with a notch, the scale bar is located in the notch, one side of the vertical module is provided with a moving device, and four second fixed blocks are fixed on the upper end of the vertical mold body, and two corresponding second fixed blocks form a group. The utility model can accurately adjust the position of the vertical module according to demand, ensures the synchronous movement of the vertical module up and down, facilitates the production of concrete components of different sizes, improves the production accuracy of concrete components, and has a protective function to prevent the mold from being damaged due to severe vibration during the oscillation process. At the same time, it has a heating function, which improves the production efficiency of concrete components. However, the above structure does not take into account the defects of the mold structure being complex, inconvenient to disassemble and assemble, and having different adaptability. In particular, after completing the production of components for a certain engineering project, these special molds are often idle or even scrapped because they cannot match the component specification requirements of the new project, resulting in a huge waste of resources. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a combination mold for concrete precast components, which aims to improve the defects of the existing technology such as complex mold structure, inconvenient disassembly and assembly, and inconsistent adaptability. In particular, after completing the production of components for a certain engineering project, these special molds are often idle or even scrapped because they cannot match the component specifications of the new project, resulting in a huge waste of resources.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a concrete precast component combination mold, including a base plate, two sides of the top surface of the base plate are fixedly connected to a frame, the outer walls of the adjacent sides of the two frames are fixedly connected to an electric push rod, the other end of the electric push rod is fixedly connected to a synchronous belt, the middle part of the outer walls of the adjacent sides of the two frames are fixedly connected to a hydraulic rod, the other end of the hydraulic rod is fixedly connected to a clamping plate, the outer wall of the clamping plate is fixedly connected to the outer wall of the synchronous belt, the top of the left frame is rotatably connected to a top cover by a hinge, the outer wall of the top cover is fixedly connected to an upper locking buckle, the outer wall of the right frame is fixedly connected to a lower buckle, the outer wall of the lower buckle is clamped and connected with the outer wall of the upper locking buckle, and positioning mechanisms are provided at both ends of the frame, and the positioning mechanism is used for docking between multiple molds.

[0007] Through the above technical solution: frames are fixedly connected on both sides of the top surface of the base plate. The frames are made of high-strength steel and have excellent stability and durability. They are firmly mounted on the base plate, providing solid support for the entire mold structure. Electric push rods are an important part of the mold adjustment structure. They can achieve precise adjustment of the mold size through precise control, and can effectively transmit power to promote the movement of the synchronous belt. The synchronous belt has a precise transmission ratio and good synchronization performance, which can ensure that the various parts of the mold maintain synchronous movement during the adjustment process, thereby achieving precise control of the mold size. The hydraulic rod can push the clamping plate to press the various parts of the mold tightly together, firmly locking the finalized mold, and the top cover facilitates the opening and closing of the mold and the pouring of concrete.

As the turbine rotates, the threaded rod fixedly connected in the middle also rotates. The function of the block is to limit the turbine to prevent it from falling off or moving accidentally. When the threaded rod rotates, the nut moves along the thread direction on the outer wall of the threaded rod. The outer wall of the nut is fixedly connected to the side wall of the frame, so that the movement of the nut can drive the frame to move accordingly, thereby realizing the locking and positioning function.

[0022] Through the above technical solution: the fixing seat 1 ensures that the electric push rod will not loosen or move during operation, the fixing seat 2 ensures that the hydraulic rod can function stably during operation, and the fixing method of screws also facilitates replacement.

[0023] As a further description of the above technical solution:
