Technical Field

[0001] The invention relates to the technical field of corrugated pipe forming machines, and in particular to a vertical 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. However, this rigid positioning method often causes the sliding seat and the mold to bear unnecessary impact force, which in turn triggers a chain reaction of mold deformation and sliding seat damage, seriously affecting the stability and production efficiency of the equipment.

[0007] Wherein, the position detection device comprises a proximity switch and a detection member matched with the proximity switch, the proximity switch is arranged on the sprocket toggle mechanism, and the detection member is arranged on the mold running platform.

[0010] Wherein, the mold running platform includes two mounting plates spaced apart on the left and right, the sprocket toggle mechanism is arranged between the two mounting plates, and the detection member is arranged on the corresponding mounting plate corresponding to the proximity switch.

[0011] Wherein, rollers are respectively arranged at the left and right ends of the sliding seat, and the running track includes track grooves correspondingly arranged on the inner sides of the two mounting plates, and the rollers are constrained in the corresponding track grooves.
