[0002] Precast concrete components are building components made in factories with concrete as the basic material. There are many types of precast concrete components, such as precast flat plates, circular hole plates, lintels, cantilever beams, etc., which are used in the main projects of civil buildings. Compared with cast-in-place concrete, factory-produced precast concrete components have many advantages, such as the quality and process of building components can be better controlled through mechanized production.

[0003] After searching, the utility model patent with announcement number CN218593284U discloses a forming mold for preparing precast concrete parts, including a moving component, a support frame, a mold, a hammering component and a control panel, wherein the moving component is symmetrically arranged at the lower end of the inner wall side of the support frame, the hammering component is evenly distributed throughout the upper wall of the support frame, the mold is rotatably arranged at the upper end of the inner wall side of the support frame and is arranged under the hammering component, and the control panel is arranged on the side of the support frame and connected to the mold; this forming mold for preparing precast concrete parts is simple to operate, compact in structure, and reasonable in design. The rotating disk rotates to drive one end of the connecting rod to move, and then drives the connecting plate to move up and down, and finally controls the telescopic rod and the hammering block to move up and down, and hammering is achieved through the contact between the hammering block and the mold, and the telescopic rod can be freely extended and retracted to avoid damage to the hammering block and the mold.

[0004] However, the above patent has the following shortcomings: it is not easy to ensure that the preform formed in the mold becomes compact, which affects the quality of the preform; and after the mold is hammered by the hammering assembly, the mold is located at a high position, and the convenience of unloading the preform is poor. For this reason, we propose a compact mold for preparing preforms. Utility Model Content
