Technical Field

[0001] The invention relates to the technical field of corrugated pipe forming machines, and in particular to a horizontal double-wall corrugated pipe forming machine. Background Art

[0002] The double-wall corrugated pipe mold is the core component of the double-wall corrugated pipe forming machine. Each double-wall corrugated pipe forming machine integrates thirty-six to forty-two pairs of precision forming molds. The key link in its efficient operation is to ensure that each pair of molds can be accurately aligned at the moment of mold closing. This is not only the key point to improve production efficiency, but also a key challenge to break through production bottlenecks and accelerate the flow of production lines.

[0003] At present, the mold closing process of all double-wall corrugated pipe forming machines requires manual adjustment to correct the slight misalignment of the mold, and then mechanical positioning is achieved by the built-in positioning pins and positioning sleeves of the mold during production.
