[0030] In this embodiment, the condensation mechanism includes a water supply pipe 401, and a spiral condenser 402 is welded at the water outlet end of the water supply pipe 401. The condenser 402 is arranged on the outside of the molding cavity 104. A water outlet pipe 403 is welded at the water outlet end of the condenser pipe 402. The water outlet pipe 403 is connected to an external circulation system. The cooled water can return to the water supply pipe 401 for recycling again, saving water resources.

While being supplied, the heating pipe 509 heats the connecting pipe 502, so that the raw materials in the temporary storage box 501 are heated for the second time, which is beneficial to prevent the problem of uneven temperature. At this time, condensed water is supplied to the condensing pipe 402 through the water supply pipe 401 to cool and mold the PVC pipe raw materials in the molding cavity 104. After cooling, the connecting block 302 is driven to move by the multi-stage electric push rod 301, and the connecting block 302 drives the sealing plate 303 to slide out, and the sealing ring 304 is removed from one side of the production box 101 to facilitate the subsequent removal of the corrugated tube.
