The oval drainage channel mold is formed by laser cutting and welding, making it easy to assemble and store. The mold design software uses CAD drawings. The annual production capacity of the mold is 50,000 units. The mold core is processed using laser technology with a processing cycle of 8. Mold parts are processed using plasma technology, with a service life of no less than 300 cycles. The demolding method for this mold involves disassembling screws, making it suitable for drainage channels.
The oval drainage channel mold appears rectangular in shape externally but is circular internally. Each steel plate has a thickness of over 3 mm and is cut and welded on a laser platform according to customer drawings. It is produced using a prefabrication method, with conventional lengths of 1 meter, 1.5 meters, and 2 meters, making it a large product among concrete channel molds. The inner mold features a cavity and a telescopic structure, including hinge seats, support rods, and locking seats on the inner mold. One end of the support rod is hinged on the hinge seat, while the other end is detachably locked with the locking seat. When the other end of the support rod is locked with the locking seat, the inner mold expands; when the support rod is separated from the locking seat, the inner mold contracts. This is the principle of one-click contraction for the inner mold of the egg-shaped channel mold. Therefore, the oval drainage channel mold is also a type of prefabricated steel mold. Due to the weight of the steel mold, it adopts an assembled structure and is installed and used in segments, which facilitates better demolding, improves construction convenience, and speeds up production.
