[0002] With the improvement of the level of building industrialization, prefabricated buildings are gradually shifting towards a construction model of standardized design, factory production and integrated decoration. PC is the abbreviation of precast concrete parts, which is called PC components in the field of residential industrialization, such as precast reinforced concrete column foundation, precast walls, precast steel structure steel column foundation, street light billboard column reinforced concrete foundation, precast floor slabs, etc. The corresponding traditional cast-in-place concrete requires on-site mold making, on-site pouring and on-site maintenance.

[0003] Precast concrete parts are widely used in the fields of construction, transportation, water conservancy, etc. The PC precast component formwork is the mold table required for the industrial production of precast components, which is convenient for batch production of PC precast components. However, there are still certain defects in the production process of PC precast walls:

[0004] The common production process of PC walls is: first pour the mixed concrete into the precast mold, and then place the precast mold filled with concrete on the mold table for extrusion and mold closing. However, during the extrusion process, the concrete will overflow from the gap between the pressing plate and the precast mold and adhere to the surface of the pressing plate, resulting in the need for manual cleaning before the pressing plate can be used again, which is very cumbersome.
