Description

Technical Field

[0001] The utility model belongs to the technical field of prefabricated component casting equipment, and specifically relates to a concrete prefabricated component casting mold. Background Art

[0002] Precast concrete components refer to building components such as beams, slabs, columns, pipes, and building decoration accessories that are pre-made in factories using concrete as the basic material and combined with steel bars. These components undergo strict production processes and quality control, and are then transported to the construction site for hoisting and installation. This production method effectively reduces wet operations on the construction site, is beneficial to energy conservation and environmental protection, and avoids waste of raw materials. However, when pouring concrete into the casting mold, gaps are likely to remain between the concrete structures and form bubbles, which affects the molding quality of the precast concrete components.

[0003] For example, the Chinese patent for a concrete precast component casting mold with the authorization announcement CN 220052181 U includes a support plate, a mold body, a vibration mechanism and a scraping mechanism. The mold body is arranged on the support plate for casting concrete; the vibration mechanism includes a first power unit and a plurality of buffer components. The output end of the first power unit is connected to the mold body for driving the mold body to vibrate. The plurality of buffer components are arranged at intervals between the mold body and the support plate for buffering the force between the mold body and the support plate; the scraping mechanism is arranged in the mold body for scraping the concrete in the mold body.

[0004] However, in the process of pouring concrete into the mold, the concrete cannot be continuously vibrated. The first power unit is started only after the pouring is completed. This practice often leads to uneven distribution of concrete, which is prone to cold joints and cannot ensure the full density of concrete and the ideal state of no bubbles and no laitance. This unevenness and the presence of bubbles and laitance will undoubtedly seriously reduce the overall quality of precast concrete components, thereby affecting the overall performance and safety of the building. Utility Model Content

[0005] The purpose of this utility model is to provide a casting mold for precast concrete components, which can continuously vibrate the concrete in the mold to ensure that the concrete is fully dense, free of bubbles and laitance, and can also accelerate the diffusion of concrete to the surroundings to avoid concrete accumulation, thereby improving the overall quality of the precast components, and thus also improving the overall performance and safety of the building.

[0006] The technical solutions adopted in this utility are as follows:

[0008] Furthermore, a material distribution support plate is fixed on the inner top wall of the upper mold and located directly below the feed pipe, and a triangular block is fixed on the top of the material distribution support plate.
