Description

Technical Field

[0001] The utility model relates to the technical field of hollow slab extrusion molding, in particular to a hollow slab extrusion molding machine for municipal housing construction. Background Art

[0002] Hollow slab, a professional term for construction, is made of concrete. The cross section of the slab is made hollow. Hollow slabs are lighter than solid slabs of the same span, easier to transport and install, and smaller in height than T-beams of the same span, so they are more commonly used in small-span bridges. There are many types of hollowing out, and an extrusion molding machine is required to manufacture and shape hollow slabs.

[0003] After searching the Chinese patent "A hollow slab extrusion molding machine for municipal housing construction", the publication number is "CN219599918U". This patent sprays a high-pressure water column through a high-pressure nozzle to prevent materials from accumulating on the surface of the stirring rod. The materials can be reused after falling off the surface of the stirring rod. The mold is then cleaned through the nozzle to make the material inside the mold fall off, reducing the impact of material accumulation in the mold on mold molding. The amount of material poured into the mold can be controlled by the flow solenoid valve to prevent the quality of the hollow slab from being unqualified due to too little material or material waste due to too much material. The use of a hydraulic press and a pressing plate makes the material more compact, further preventing material waste while improving the quality of the hollow slab. However, the device is not convenient for rapid extrusion molding of the hollow slab during use, which reduces the use effect of the device.

[0004] Therefore, a kind of municipal house construction hollow plate extrusion forming machine is proposed to solve the above problems. Utility Model Content
