Problems solved by technology

[0002] Most of the existing plastic corrugated pipes are formed by blow-up molding. In order to maintain the pressure in the unformed pipe, there is an air block in the pipe. Wear iron wire; the method of vacuum forming can make bellows with ribs in the tube and small-scale tubes that can wear iron wire, but the module for vacuum forming is difficult to process, the precision is high, and the equipment is expensive; both of the above have equipment defects. The operation is difficult, and it is difficult for ordinary people to master the operation technology. The stability of the equipment is not good. It needs frequent careful observation and careful adjustment to ensure the quality of the bellows produced. If you do not pay attention to observation, it is easy to produce defective products.

Abstract

The invention discloses a module for extruding and forming a plastic corrugated pipe, which comprises a left half module and a right half module, wherein one ends of the left half module and the right half module are connected together through a connecting mechanism to form a hinge shape; the left half module and the right half module are merged together in a die assembly state, and the other ends of the left half module and the right half module, which are not connected together, are opened for a certain angle in a die sinking state. The module provided by the invention is aligned in the die assembly state and the die sinking state without misplacement; the traditional module is changed by using a die assembly manner of the module, and the cost is lowered; each module is formed through the same die and the same set of punching die, thus the processing speed is high and the precision is high; and gaps required for vacuumizing are remained among the modules during the assembly without excessive processing, thus heat radiation property is good and the modules are conveniently cooled.

Description

technical field [0001] The invention relates to a plastic bellows extrusion molding device, in particular to a module for plastic bellows extrusion molding. Background technique [0002] Most of the existing plastic corrugated pipes are formed by blow-up molding. In order to maintain the pressure in the unformed pipe, there is an air block in the pipe. Wear iron wire; the method of vacuum forming can make bellows with ribs in the tube and small-scale tubes that can wear iron wire, but the module used for vacuum forming is difficult to process, high in precision, and expensive in equipment; both of the above have equipment defects. The operation is difficult, and it is difficult for ordinary people to master the operation technology. The stability of the equipment is not good. It needs frequent careful observation and careful adjustment to ensure the stable quality of the bellows produced. If you do not pay attention to observation, it is easy to produce defective products. ...
