Description

Technical Field

[0001] The invention relates to the technical field of concrete demoulding equipment, in particular to a demoulding device in a concrete production line. Background Art

[0002] At present, reinforced concrete sleepers are widely used. When producing such sleepers, steel bars are set in steel molds and concrete is injected to form them. Then the finished sleepers are separated from the molds. At present, sleeper molds are generally single-group structures or mold structures of several groups of sleepers connected together. The demoulding method is generally to remove the sleeve bolts by manually holding tools close to the mold. The mold demoulding adopts equipment to lift, flip and knock to demould the prefabricated sleepers.

[0003] However, the above pouring and demoulding method can only open the mold horizontally and lay it flat, and then control the injection port to pour back and forth at the opening. The back and forth movement of the discharge end must necessarily require the installation of an additional drive structure, which greatly increases the maintenance cost. At the same time, when demoulding, the mold needs to be flipped 180 degrees in the air, which also has a great burden on the folding structure, thereby indirectly affecting the service life of the structure.
